RESUMEN

Introduction: Phenytoin is one of the commonly used anti.seizure medications in nontraumatic seizures. However, its utility and safety in young patients with traumatic brain injury (TBI) for the prevention of early-onset seizures (EOS) are debatable. We sought to explore the use of phenytoin as a seizure prophylaxis following TBI. We hypothesized that administering phenytoin is not effective in preventing EOS after TBI. Methods: This was a retrospective observational study conducted on adult TBI patients. EOS was defined as a witnessed seizure within a week postinjury. Data were compared as phenytoin versus no-phenytoin use, EOS versus no-EOS, and among TBI severity groups. Results: During 1 year, 639 TBI patients were included with a mean age of 32 years; of them, 183 received phenytoin as seizure prophylaxis, and 453 received no prophylaxis medication. EOS was documented in 13 (2.0%) patients who received phenytoin, and none had EOS among the nonphenytoin group. The phenytoin group was more likely to have a higher Marshall Score (P = 0.001), lower Glasgow Coma Scale (GCS) (P = 0.001), EOS (P = 0.001), and higher mortality (P = 0.001). Phenytoin was administrated for 15.2%, 43.2%, and 64.5% of mild, moderate, and severe TBI patients, respectively. EOS and no-EOS groups were comparable for age, gender, mechanism of injury, GCS, Marshall Score, serum phenytoin levels, liver function levels, hospital stay, and mortality. Multivariable logistic regression analysis showed that low serum albumin (odds ratio [OR] 0.81; 95% confidence interval [CI] 0.676.0.962) and toxic phenytoin level (OR 43; 95% CI 2.420.780.7) were independent predictors of EOS. Conclusions: In this study, the prophylactic use of phenytoin in TBI was ineffective in preventing EOS. Large-scale matched studies and well-defined hospital protocols are needed for the proper utility of phenytoin post-TBI.

RESUMEN

Background. The use of oral or nasal route for enteral feeding is a standard practice in intensive care patients with a safe profile in general. However, complications associated with the insertion of a nasogastric (NGT) or orogastric tube (OGT) are common in the medical literature compared to the removal of such tubes. Case presentation. We presented a 38-year-old male who was involved in a motor-vehicle collision and found with low Glasgow Coma Scale outside his vehicle. He had polytrauma and was intubated-and commenced on enteral feeding via an OGT. Esophageal bezoar developed within a few days around the feeding tube, resulting in significant force being required to remove it, which was complicated by esophageal perforation. The esophageal injury was treated conservatively with uneventful recovery. Discussion and conclusions. Although limited case reports of esophageal enteral feeding bezoar formation do exist in the literature, we believe that this is the first case report of esophageal perforation due to the forceful removal of a wedged OGT secondary to esophageal bezoar formation. Morbidity associated with OGT/NGT is not common and may require a high index of suspicion to be identified. This is especially true if resistance is appreciated while removing the NGT/OGT. Gastroenterology consultation is recommended as early as possible to detect and manage any complications, however, their role was very limited in such stable case. In addition, early computed tomography (CT) can be considered for timely recognition of esophageal perforation. Non-operative management may be considered in stable patients, especially if the leak is in the cervical portion of the esophagus. Finally, prevention is better than cure, so being diligent in confirming NGT/OGT position, both radiologically and by measuring the tube length at the nostril/mouth, is the key to avoid misplacement and complication. This case raises the awareness of physician for such preventable iatrogenic event.

RESUMEN

Background: We sought to evaluate the predictor role of the initial serum level of calcium and magnesium in hospitalized traumatic brain injury (TBI) patients. Materials and methods: A retrospective analysis of all TBI patients admitted to the Hamad Trauma Center (HTC), between June 2016 and May 2021 was conducted. Initial serum electrolyte levels of TBI patients were obtained. A comparative analysis of clinical variables between patients with abnormal and normal serum electrolyte level was performed. Logistic regression analysis with the variables that showed a significant difference (p < 0.05) in the bivariate analysis was performed to calculate the odds ratios (OR) for mortality. Results: There was a total of 922 patients with clinical records of serum electrolyte levels at admission. Of these, 757 (82.1%) had hypocalcemia, 158 (17.1%) had normal calcium level, and 7 (0.8%) had hypercalcemia. On the other hand, 616 (66.8%) patients had normal magnesium level, 285 (30.9%) had hypomagnesemia, and 12 (1.3%) had hypermagnesemia. The mortality rate in hypocalcemia group was 24% while in patients with normal calcium level it was 12%, p = 0.001. Proportionate mortality rates in hypomagnesemia and normal magnesium groups were 15% and 23% (p = 0.006), respectively. On the other hand, 7 out of 12 (58%) hypermagnesemia patients died during the index hospitalization. The regression model including GCS, ISS, PT, aPTT, INR, Hemoglobin, Bicarbonate, Lactate, Sodium, Potassium, Calcium, Magnesium, and Phosphate showed that hypocalcemia was not a significant predictor [OR 0.59 (CI 95%: 0.20-1.35)] of mortality after TBI. However, hypermagnesemia was a significant predictor [OR 16 (CI 95%: 2.1-111)] in addition to the GCS, ISS, aPTT, Bicarbonate, and Lactate values on admission. Conclusion: Although hypocalcemia and hypomagnesemia are common in hospitalized TBI patients, hypocalcemia was not a significant predictor of mortality, while hypermagnesemia was an independent predictor. Further studies with larger sample size and with prospective design are required to support these findings and their importance.

RESUMEN

Background: We aimed to assess the prognostic value of Rotterdam and Marshall scoring systems to predict in-hospital mortality in patients with traumatic brain injury (TBI).Methods: A retrospective analysis was conducted for patients with TBI who underwent head computerized tomography (CT) scan at a Level I trauma center between 2011 and 2018. Receiver operating characteristic (ROC) curves were used to determine the cutoff values for predicting in-hospital mortality.Results: A total of 1035 patients with TBI were included with a mean age of 30 years. The mean Rotterdam and Marshall scores were higher among non-survivors (p = .001). Patients with higher Rotterdam (>3) or Marshall (>2) CT scores were older, had higher injury severity scores and in-hospital mortality and had lower GCS and blood ethanol levels than those with lower scores. The cutoff point of Rotterdam score was 3.5 (sensitivity, 61.2%; specificity, 85.6%) and Marshall score was 2.5 (74.3% sensitivity and 76.3% specificity). Multivariable logistic regression analyses showed that Marshall and Rotterdam scoring systems were independent predictors of mortality (odds ratio 8.4; 95% confidence interval 4.95-14.17 and odds ratio 4.4; 95% confidence interval 2.36-9.39, respectively).Conclusion: Rotterdam and Marshall CT scores have independent prognostic values in patients with TBI even in alcoholic patients.

RESUMEN

BACKGROUND: As trauma systems mature, they are expected to improve patient care, reduce in-hospital complications and optimize outcomes. Qatar has a single trauma center, at the Hamad General Hospital, which serves as the hub for the trauma system that was verified as a level 1 trauma system by the Accreditation Canada International Distinction program in 2014. We hypothesized that this international accreditation was a major step, in the maturation process of the Qatar trauma system, that has positively impacted patient care, reduced complications and improved outcomes of trauma patients in such a rapidly developing country. METHODS: A retrospective analysis of data was conducted for all trauma patients who were admitted between 2010 and 2018. Data were obtained from the level 1 trauma center registry at Hamad Medical Corporation. Patients were divided into Group 1- pre-accreditation (admitted from January 2010 to October 2014) and Group 2- post-accreditation (admitted from November 2014 to December 2018). Patients' characteristics and in-hospital outcomes were analyzed and compared. Data included patients' demographics; injury types, mechanism and injury severity scores, interventions, hospital stay, complications and mortality (pre-hospital and in-hospital). Time series analysis for mortality was performed using expert modeler. RESULTS: Data from a total of 15,864 patients was collected and analyzed. Group 2 patients had more severe injuries in comparison to Group 1 (p<0.05). However, Group 2, had a lower complication rate (ventilator associated pneumonia (VAP)) and a shorter mean hospital length of stay (p<0.05). The overall mortality was 8%. In Group 2; the pre-hospital mortality was higher (52% vs. 41%, p = 0.001), while in-hospital mortality was lower (48% vs. 59%) compared to Group 1 (p = 0.001). CONCLUSIONS: The international recognition and accreditation of the trauma center in 2014 was the key factor in the maturation of the trauma system that improved the in-hospital outcomes. Accreditation also brought other benefits including a reduction in VAP and hospital length of stay. However, further studies are required to explore the maturation process of all individual components of the trauma system including the prehospital setting.

RESUMEN

BACKGROUND: Suicide is a complex phenomenon involving several risk factors. We aimed to describe the frequency, pattern, and outcomes of patients with traumatic injuries following suicide attempts admitted to a level 1 trauma center. METHODS: We conducted a retrospective analysis of data obtained from Qatar National Trauma Registry and mortuary database. The study included all patients with traumatic injuries following suicide attempts, admitted to the Hamad Trauma Center (HTC) from April 2008 to March 2018. RESULTS: During this 10-year period, 206 patients were admitted to the HTC for injuries associated with suicide attempts. The majority were males (76%), young age (mean age 31 years), and expatriates specifically from South Asia (55%). The most common injury was due to self-inflicted cutting and piercing (51%) followed by jumping from height (30%). Females chose jumping from high place more often as a method of suicide attempt (59% vs. 20%), while males chose self-stabbing or cutting their throat (59% vs. 25%) (P = 0.001). Most of the patients had head injuries (30%) that was severe in terms of abbreviated injury scale score (3.6 ± 0.9). More than half (54%) of the patients required psychiatric consultations. The in-hospital mortality was 8% which was comparable in both genders. CONCLUSIONS: The present study revealed that 1.8% of trauma admissions at HTC were related to suicidal attempts. Better understanding of risk factors is important in devising preventive strategies.

RESUMEN

Background: We aimed to assess the management and outcome of occult pneumothorax and to determine the factors associated with failure of observational management in patients with blunt chest trauma (BCT). Methods: Patients with BCT were retrospectively identified from the trauma database over 4 years. Data were analyzed and compared on the basis of initial management (conservative vs. tube thoracostomy). Results: Across the study period, 1928 patients were admitted with BCT, of which 150 (7.8%) patients were found to have occult pneumothorax. The mean patient age was 32.8 ± 13.7 years, and the majority were male (86.7%). Positive-pressure ventilation (PPV) was required in 32 patients, and bilateral occult pneumothorax was seen in 25 patients. In 85.3% (n = 128) of cases, occult pneumothorax was managed conservatively, whereas 14.7% (n = 22) underwent tube thoracostomy. Five patients had failed observational treatment requiring delayed tube thoracostomy. Pneumonia was reported in 12.8% of cases. Compared with those who were treated conservatively, patients who underwent tube thoracostomy had thicker pneumothoraxes and a higher rate of lung contusion, rib fracture, pneumonia, prolonged ventilatory days, and prolonged hospital length of stay. Overall mortality was 4.0%. The deceased had more polytrauma and were treated conservatively without a chest tube. Patients who failed conservative management had a higher frequency of lung contusion, greater pneumothorax thickness, higher Injury Severity Scores (ISS), and required more PPV. Conclusions: Occult pneumothorax is not uncommon in BCT and can be successfully managed conservatively with a close clinical follow-up. Intervention should be limited to patients who have an increase in size of the pneumothorax on follow-up or become symptomatic under observation. Patients who fail conservative management may have a greater pneumothorax thickness and higher ISS. However, large prospective studies are warranted to support these findings and to establish the institutional guidelines for the management of occult pneumothorax.

RESUMEN

Traumatic injuries accounted for substantial burden of morbidity and mortality (M and M) worldwide. Despite better socioeconomic conditions and living standards, the incidence of trauma is rising in the Eastern Mediterranean Region (EMR). Road traffic injuries are the leading cause of the high fatality rate in young economically productive adults in our region. The provision of trauma care at high-volume, accredited trauma center by a team of dedicated full-time professional health-care providers has been shown to improve the quality of care and the outcomes for trauma victims. With persistent hard work and effective leadership, in Qatar, the Trauma Section has evolved into a well-reputed and internationally recognized Center of Excellence in Trauma Care, Hamad Level 1 Trauma Center. In 2014, Qatar Trauma System was accredited with Trauma Distinction Award by the Accreditation Canada International, for high-quality trauma care of severely injured patients; first in the Middle East. The Hamad Trauma Center is committed to the advancement of trauma care in different aspects right from the immediate prehospital care to the subsequent hospital-based care, involving diagnosis, treatment, support, rehabilitation, and community reintegration of the patients and injury prevention. Our trauma system has gradually embedded with a structured and matured research unit with dedicated clinicians and academic researchers. The trauma team embodies the 21st-century paradigm of translational research and injury prevention by going well beyond the bedside, out into the populations that need it most. The trauma system's future vision relies on the evidence-based health-care service and better outcomes; state-of-the-art infrastructure and multidimensional collaborations with health care and governmental services to minimize the burden of M and M caused by traumatic injury in the State of Qatar and to fulfill the population health enhancement strategy.

RESUMEN

PURPOSE: We aimed to assess the pattern and impact of sternal injury with rib fracture in a Level 1 trauma center. PATIENTS AND METHODS: We conducted a retrospective review of trauma registry data to identify patients who presented with sternal fracture between 2010 and 2017. Data were analyzed and compared in patients with and without rib fracture. RESULTS: We identified 212 patients with traumatic sternal injury, of them 119 (56%) had associated rib fractures. In comparison to those who had no rib fracture, patients with rib fractures were older (40.1 ± 13.6 vs. 37.8 ± 14.5), were frequently involved in traffic accidents (75% vs. 71%), had higher chest abbreviated injury scale (AIS 2.8 ± 0.6 vs. 2.2 ± 0.5) and Injury Severity Score ( ISS 17.5 ± 8.6 vs. 13.3 ± 9.6), were more likely to be intubated (33% vs. 19%), required chest tube insertion (13.4% vs. 4.3%), and received blood transfusion (29% vs. 17%). Rates of spine fracture, head injury, and solid organ injury were comparable in the two groups. Manubrium, clavicular and scapular fractures, lung contusion, hemothorax, and pneumothorax were significantly more evident in those who had rib fractures. Hospital length of stay was prolonged in patients with rib fractures (P = 0.008). The overall mortality was higher but not statistically significant in patients with rib fractures (5.0% vs. 3.2%). CONCLUSIONS: Sternal fractures are rare, and detection of associated injuries requires a high index of suspicion. Combined sternal and rib fractures are more evident in relatively older patients after chest trauma. This combination has certain clinical implications that necessitate further prospective studies.

RESUMEN

INTRODUCTION: We aimed to investigate in-hospital outcomes of traumatic brain injury (TBI) based on blood alcohol concentration (BAC) and mechanism of injury (MOI). METHODS: We conducted a retrospective study for patients admitted with TBI between 2010 and 2014. Based on BAC, patients were classified into [negative (-BAC) and positive (+BAC) group]. Data were analyzed and compared according to the MOI. RESULTS: Out of 8141 trauma patients, 946 (11.6%) were diagnosed with TBI and 681 (72%) were subjected to BAC screening. One out of seven TBI was related to alcohol consumption with a mean age of 32 years. Gender, age, and Injury Severity Scores (ISS) were comparable in the two groups. However, the proportion of patients with polytrauma was significantly higher in -BAC than +BAC group regardless of the MOI except for the fall-related TBI. The median BAC was higher in fall-related followed by pedestrians and MVC victims [55 mmol/L (10-101), 49(9-71), and 31(1-69), respectively], p = 0.001. Overall hospital mortality was comparable between the two groups except for the pedestrian-related TBIs in which (+BAC) had significantly fewer mortality. CONCLUSIONS: Screening for BAC among patients with TBI increases substantially regardless of the MOI. The high BAC value in Fall-related TBI needs more attention to set appropriate preventive measures.

RESUMEN

Trauma is a leading cause of mortality and morbidity worldwide, and thus represents a great global health challenge. The World Health Organization (WHO) estimated that 9% of deaths in the world are the result of trauma.1 In addition, approximately 100 million people are temporarily or permanently disabled every year.2 The situation is no different in Qatar, and injury related morbidity and mortality is increasing in the entire region, with road traffic collisions (RTCs) being the most common mechanism.1 It is well recognized now that trauma care provided in high-volume, dedicated, level-one trauma centers, improves outcome. Studies have also looked at what are the components of a trauma system that contribute to their effectiveness2. However, in general, it usually implies a high-volume of cases, dedicated full-time trauma qualified professionals, a solid pre-hospital system, a multidisciplinary team, and excellent rehabilitation services. Similarly, critically injured trauma patients managed in a dedicated trauma intensive care unit (TICU), has been shown to improve outcomes, especially for polytrauma patients with traumatic brain injury (TBI).3 In fact, the American College of Surgeons (ACS) Committee on Trauma requires verified trauma centers to have a designated ICU, and that a trauma surgeon be its director.4 Furthermore, studies have shown that for TBI, it is not necessary for this ICU to be a neurocritical care unit, but rather it should be a unit that is dedicated to trauma, that has standardized protocols for TBI management.5,6 In fact, the outcomes are better in the latter, with lower mortality in multiple-injured patients with TBI, when admitted to a TICU (versus a medical-surgical ICU or neurocritical care unit).3 These benefits were shown to increase, with increased injury severity. The proposed reason for this is thought to be due to the associated injuries being managed better.7 The aim of this editorial is to describe the TICU at Hamad General Hospital (HGH), at Hamad Medical Corporation (HMC), including a comparison of its data and outcomes with other similar trauma centers in the world. The Qatar Trauma Registry, as well as previous publications from our Trauma Center,1,8 were used to obtain HGH TICU and worldwide Level-1 Trauma Center standards, respectively. With respect to HGH, the TICU is part of an integrated trauma program, the only level-1 trauma centre in Qatar. It provides the highest standard of care for critically-ill trauma patients admitted at HGH, striving to achieve the best outcomes, excellence in evidence-based patient care, up to date technology, and a high level of academics in research and teaching. This integrated program includes an excellent pre-hospital unit, emergency and trauma resuscitation unit, TICU, trauma step-down unit (TSDU), inpatient ward, and rehabilitation unit. The new TICU is a closed 19-bed unit, that was inaugurated in 2016, is managed 24/7 by highly qualified and experienced intensivists (9 senior consultants and consultants), along with 24 well-trained and experienced associate consultants or specialists, and fellows and residents in training, as well as expert nursing staff (1:1 nurse to patient ratio) and allied health professionals (respiratory therapists, pharmacists, dieticians, physiotherapists, occupational therapists, social workers, case managers, and psychologists). It is supported by all medical and surgical subspecialty services. It is equipped with the latest state-of-the-art technology and equipment, including 'intelligent ventilators", neuro-monitoring devices, ultrasound, point-of-care testing such as arterial blood gas and rotational thromboelastrometry (ROTEM), and video airway devices. The TICU is a teaching unit, linked to the HMC Medical Education department, with presence of fellows, and residents (see below for details). Medical students (Clerkship level) from Weill-Cornell Medicine Qatar also complete a one-week rotation in the TICU, as part of their exposure to critical care. The first batch of clerks from Qatar University College of Medicine are expected to start rotating in the TICU soon. The Trauma Critical Care Fellowship Program (TCCFP) is an ACGME (Accreditation Council for Graduate Medical Education) fellowship that was established over seven years ago. To date, over 40 physicians from both within, and out of, the trauma department have completed the program. Up to seven fellows, including international candidates, are trained each year. A number of physicians have succeeded in gaining the European Diploma of Intensive Care Medicine (EDIC). The program continues to attract many applicants from various specialties including surgery, anesthesia, and emergency medicine. An increasing number of international physicians from Europe and South America have expressed interest in applying for our fellowship. The first international fellows are likely to join us from early 2020. Residents (from general surgery, ER, ENT, plastics, orthopedics, and neurosurgery) rotate (one to three months' rotations) in the TICU, and are actively part of the clinical team. There were 568 admissions to the TICU in 2018. The patients admitted were either mainly polytrauma patients with varying degrees and combinations of head, chest, abdominal, pelvic, spine, and orthopedic injuries, or isolated-TBI. Of these patients, 378 were severely injured with an injury severity score (ISS)9 greater than 16. According to previously published data from our Trauma Centre,1,8 our mortality rates (overall approximately 6-7%, as well as when looked at in terms of early and late deaths) compare favorably with other trauma centers around the world, when looking at similarly sized retrospective studies. The TICU continues to be an active member of the Critical Care Network of HMC.10 This network involves all of the ICU's in all the HMC facilities. The main processes that the TICU is presently involved in as part of this network are: patient flow, clinical practice guidelines, evaluation and procurement of technologies, HMC sepsis program, and in general, taking part in any process that pertains to critical care at HMC. A number of quality improvement projects are being undertaken in the TICU. Examples of such projects include: - Decreasing rates of infection in TICU- Score-guided sedation orders to decrease sedation use, ventilator days and length of stay- Reducing blood taking and associated costs- Sepsis alert response and bundle compliance- Medical and surgical management of rib fracturesA multidisciplinary team of physicians, nurses, and allied health professionals participate in these projects, and meet once a month to review all projects. Similarly, many research projects are taking place in the TICU, in coordination with the Trauma Research program, and often in collaboration with other departments (local and international). Examples of some of the research projects include: - The "POLAR" study (RCT on Hypothermia in TBI)11- B-blockers in TBI (RCT-ongoing)- Tranexamic acid (TXA) for bleeding in trauma (RCT-ongoing) The team is also involved in conducting systematic reviews in relation to the role of transcranial doppler in TBI,12 sepsis in TBI patients (ongoing), self-extubation in TBI patients,13 safety and efficacy of phenytoin in TBI (ongoing), and optic nerve diameter for predicting outcome in TBI (submitted). The TICU at HGH is a high-volume, high acuity unit that manages all the severely injured trauma patients in Qatar. It is well staffed with highly trained and qualified personnel, and utilizes the latest in technology and state-of-the-art equipment. It performs very well, when compared to other similar units in the world, and achieves a comparable, or even lower mortality rate. With continued great support from the hospital, corporation administration, and Ministry of Public Health, the future goals of the TICU will be to maintain and improve upon the high standards of clinical care it provides, as well as perform a high quality and quantity of research, quality improvement initiatives, and educational work, in order for it to be amongst the best trauma critical care units in the world.

RESUMEN

INTRODUCTION: Traumatic brain injury is a major cause of morbidity and mortality worldwide, and has been reported to be one of the risk factors for epileptic seizures. Abnormal blood lactate (LAC) and base deficit (BD) reflects hypoperfusion and could be used as metabolic markers to predict the outcome. The aim of this study is to assess the prognostic value of BD and LAC levels for post traumatic convulsion (PTC) in head injury patients. MATERIALS AND METHODS: All head injury patients with PTC were studied for the demographics profile, mechanism of injury, initial vital signs, and injury severity score (ISS), respiratory rates, CT scan findings, and other laboratory investigations. The data were obtained from the trauma registry and medical records. Statistical analysis was done using SPSS software. RESULTS: Amongst 3082 trauma patients, 1584 were admitted to the hospital. Of them, 401 patients had head injury. PTC was observed in 5.4% (22/401) patients. Out of the 22 head injury patients, 10 were presented with the head injury alone, whereas 12 patients had other associated injuries. The average age of the patients was 25 years, comprising predominantly of male patients (77%). Neither glasgow coma scale nor ISS had correlation with BD or LAC in the study groups. The mean level of BD and LAC was not statistically different in PTC group compared to controls. However, BD was significantly higher in patients with associated injuries than the isolated head injury group. Furthermore, there was no significant correlation amongst the two groups as far as LAC levels are concerned. CONCLUSION: Base deficit but not lactic acid concentration was significantly higher in head injury patients with associated injuries. Early resuscitation by pre-hospital personnel and in the trauma room might have impact in minimizing the effect of post traumatic convulsion on BD and LAC.

RESUMEN

INTRODUCTION: Restraint systems (seat belts and airbags) are important tools that improve vehicle occupant safety during motor vehicle crashes (MVCs). We aimed to identify the pattern and impact of the utilization of passenger restraint systems on the outcomes of MVC victims in Qatar. METHODS: A retrospective study was conducted for all admitted patients who sustained MVC-related injuries between March 2011 and March 2014 inclusive. RESULTS: Out of 2,730 road traffic injury cases, 1,830 (67%) sustained MVC-related injuries, of whom 88% were young males, 70% were expatriates, and 53% were drivers. The use of seat belts and airbags was documented in 26 and 2.5% of cases, respectively. Unrestrained passengers had greater injury severity scores, longer hospital stays, and higher rates of pneumonia and mortality compared to restrained passengers (P = .001 for all). There were 311 (17%) ejected cases. Seat belt use was significantly lower and the mortality rate was 3-fold higher in the ejected group compared to the nonejected group (P = .001). The overall mortality was 8.3%. On multivariate regression analysis, predictors of not using a seat belt were being a front seat passenger, driver, or Qatari national and young age. Unrestrained males had a 3-fold increase in mortality in comparison to unrestrained females. The risk of severe injury (relative risk [RR] = 1.82, 95% confidence interval [CI], 1.49-2.26, P = .001) and death (RR = 4.13, 95% CI, 2.31-7.38, P = .001) was significantly greater among unrestrained passengers. CONCLUSION: The nonuse of seat belts is associated with worse outcomes during MVCs in Qatar. Our study highlights the lower rate of seat belt compliance in young car occupants that results in more severe injuries, longer hospital stays, and higher mortality rates. Therefore, we recommend more effective seat belt awareness and education campaigns, the enforcement of current seat belt laws, their extension to all vehicle occupants, and the adoption of proven interventions that will assure sustained behavioral changes toward improvements in seat belt use in Qatar.

RESUMEN

BACKGROUND: The incidence of abdominal trauma is still underreported from the Arab Middle-East. We aimed to evaluate the incidence, causes, clinical presentation, and outcome of the abdominal trauma patients in a newly established trauma center. MATERIALS AND METHODS: A retrospective analysis was conducted at the only level I trauma center in Qatar for the patients admitted with abdominal trauma (2008-2011). Patients demographics, mechanism of injury, pattern of organ injuries, associated extra-abdominal injuries, Injury Severity Score (ISS), Abbreviated Injury Scale, complications, length of Intensive Care Unit, and hospital stay, and mortality were reviewed. RESULTS: A total of 6888 trauma patients were admitted to the hospital, of which 1036 (15%) had abdominal trauma. The mean age was 30.6 ± 13 years and the majority was males (93%). Road traffic accidents (61%) were the most frequent mechanism of injury followed by fall from height (25%) and fall of heavy object (7%). The mean ISS was 17.9 ± 10. Liver (36%), spleen (32%) and kidney (18%) were most common injured organs. The common associated extra-abdominal injuries included chest (35%), musculoskeletal (32%), and head injury (24%). Wound infection (3.8%), pneumonia (3%), and urinary tract infection (1.4%) were the frequently observed complications. The overall mortality was 8.3% and late mortality was observed in 2.3% cases mainly due to severe head injury and sepsis. The predictors of mortality were head injury, ISS, need for blood transfusion, and serum lactate. CONCLUSION: Abdominal trauma is a frequent diagnosis in multiple trauma and the presence of extra-abdominal injuries and sepsis has a significant impact on the outcome.

RESUMEN

OBJECTIVE: We aimed to evaluate whether early administration of high plasma to red blood cells ratios influences outcomes in injured patients who received massive transfusion protocol (MTP). METHODS: A retrospective analysis was conducted at the only level 1 national trauma center in Qatar for all adult patients(≥18 years old) who received MTP (≥10 units) of packed red blood cell (PRBC) during the initial 24 h post traumatic injury. Data were analyzed with respect to FFB:PRBC ratio [(high ≥ 1:1.5) (HMTP) vs. (low < 1:1.5) (LMTP)] given at the first 4 h post-injury and also between (>4 and 24 h). Mortality, multiorgan failure (MOF) and infectious complications were studied as well. RESULTS: During the study period, a total of 4864 trauma patients were admitted to the hospital, 1.6 % (n = 77) of them met the inclusion criteria. Both groups were comparable with respect to initial pH, international normalized ratio, injury severity score, revised trauma score and development of infectious complications. However, HMTP was associated with lower crude mortality (41.9 vs. 78.3 %, p = 0.001) and lower rate of MOF (48.4 vs. 87.0 %, p = 0.001). The number of deaths was 3 times higher in LMTP in comparison to HMTP within the first 30 days (36 vs. 13 cases). The majority of deaths occurred within the first 24 h (80.5 % in LMTP and 69 % in HMTP) and particularly within the first 6 h (55 vs. 46 %). CONCLUSIONS: Aggressive attainment of high FFP/PRBC ratios as early as 4 h post-injury can substantially improve outcomes in trauma patients.

RESUMEN

OBJECTIVES: We aimed to analyze the pattern and outcome of traumatic neck injury (TNI) in a small population. MATERIALS AND METHODS: It is a retrospective analysis of all TNI patients who were admitted to the trauma center between 2008 and 2012. Patients' demographics, details of TNI, associated injuries, hospital course, and mortality were analyzed. RESULTS: A total of 51 TNI cases were included revealing an overall incidence of 0.61/100,000 population. The mean age was 31 ± 9 years. The most frequent mechanism of injury was motor vehicle crash (29.4%) followed by stab (17.6%), machinery injury (17.6%), fall (9.8%), and assault (7.8%). Larynx, thyroid gland, trachea, jugular veins, and carotid were the commonly injured structures. The majority of cases had Zone II TNI whereas isolated injury was observed in 11 cases. TNI were mainly presented with active bleeding (38%), hypovolemic shock (16%) and respiratory distress (16%). Surgical interventions mainly included simple repair and closure (53%), vein ligation (12%), repair of major arteries (4%), tracheal repair (6%), larynx and hypopharynx repair (4%), and repair of parotid gland (2%). Neck exploration was performed in 88%, and emergency tracheostomy was required in 18% of cases. Overall mortality rate was 11.8%, of which five patients had associated injuries, and one had isolated TNI. CONCLUSION: TNI are not frequent but represent an alarming serious entity in Qatar. Patients with persistent signs of major injuries should undergo early operative interventions. Moreover, the effective injury prevention program should be developed to minimize these preventable injuries in the majority of cases.

RESUMEN

Qatar is a rapidly developing country in which expatriate workers constitute the majority of population. Also, Qatar is an example of right-sided road driving convention (RDC) country. The aim of our study is to analyse the traffic-related pedestrian injuries (TRPI) amongst expatriates in relation to RDC. A retrospective analysis of prospectively collected data of TRPI patients who were admitted to the only Level I trauma centre in Qatar between 2009 and 2011 was performed. Demographics, country of origin, time of injury, injury severity score (ISS), RDC, morbidity and mortality were analysed. Of the 4997 injured patients, 601 (12%) were pedestrians. Of these, 92% were expatriates. The mean age was 31.8 ± 17 and 64% of them were 18-45 years old. Mean ISS was higher in those who were injured on weekends (15.4 ± 10) in comparison to working days (13.5 ± 10) (p = 0.04). The overall mortality was 15%. Sixty-seven percent of those who died were from left RDC countries. Expatriate workers, originally from left RDC countries are disproportionately affected by TRPI. This group of injured patients requires focused injury prevention programmes that are culture and language appropriate.

RESUMEN

BACKGROUND: The mechanism and outcome of traumatic abdominal injury (TAI) varies worldwide. Moreover, data comparing TAIs in each abdominal compartment are lacking. We aimed to assess from the academic point of view, TAI based on its anatomical compartments. PATIENTS & METHODS: We conducted a retrospective study for TAI patients between 2008 and 2011 in Qatar. Patients were categorized according to the involved anatomical compartment (C): intrathoracic (ITC), retroperitoneal (RPC), true abdomen (TAC), and pelvic abdomen (PAC) group. Chi Square test, One-Way ANOVA and multivariate regression analysis were appropriately performed. RESULTS: Of 6,888 patients admitted to the trauma unit, 1,036 (15%) had TAI that were grouped as ITC (65%), RPC (15%), TAC (13%), and PAC (7%). The mean age was lowest in ITC (29 ± 13) and highest in TAC (34 ± 11) group, (P = 0.001). Motor vehicle crash was the main mechanism of injury in all groups except for PAC, in which fall dominated. Vast majority of expatriates had PAC and TAC injuries. The main abdominal injuries included liver (35%; ITC), spleen (32%; ITC) and kidneys (18%; RPC). Extra-abdominal injuries involved the head in RPC and ITC, lung in ITC and RPC and extremities in PAC. Mean ISS was higher in RPC and ITC. Abdominal AIS was higher in TAC injuries. Overall hospital mortality was 10%: RPC (15%), TAC (11%), ITC (9.4%) and PAC (1.5%). Concurrent traumatic brain injury (OR 5.3; P = 0.001) and need for blood transfusion (OR 3.03; P = 0.003) were the main independent predictors of mortality. CONCLUSION: In addition to its academic value, the anatomical approach of TAI would be a complementary tool for better understanding and prediction of the pattern and outcome of TAI. This would be possible if further research find accurate, early diagnostic tool for this anatomical classification.

RESUMEN

BACKGROUND: Bispectral index (BIS) monitoring in multiple trauma patients has become a common practice in monitoring the sedation levels. We aimed to assess the utility of BIS in the trauma intensive care unit (ICU). METHODS: A prospective observational study was conducted in the trauma ICU at Hamad General Hospital in Qatar between 2011 and 2012. Patients were divided in two groups: Group I (without BIS monitoring) and Group II (with BIS monitoring). The depth of sedation was clinically evaluated with Ramsey Sedation Scale, changes in vital signs and Glasgow Coma Scale (GCS) level. Use of sedatives, analgesics, and muscle relaxants were also recorded. Data were compared using Chi-square and Student t-tests. RESULTS: A total of 110 mechanically ventilated trauma patients were enrolled with a mean age of 36 ± 14 years. The rate of head injury was greater in Group I when compared with Group II (94% vs. 81%, P = 0.04). In comparison to Group I, patients in Group II had lower GCS and higher mean Injury Severity Score (ISS) (6.3 ± 2.5 vs. 7.4 ± 2.7 and 25.5 ± 8.5 vs. 21.2 ± 4.7, respectively, P = 0.03). The used midazolam dose was less in Group II in comparison to Group I (5.2 ± 2.3 vs. 6.1 ± 2.1, P = 0.03). Also, fentanyl dose was less in Group II (152 ± 58 vs. 187 ± 59, P = 0.004). The rate of agitation, failure of extubation and tracheostomy in Group II were lower than those in Group I, P = 0.001. The length of stay for patients Group I was longer (14.6 ± 7.1 vs. 10.2 ± 5.9 days) in comparison to group II, P = 0.001. CONCLUSION: Management of multiple trauma patients in the trauma ICU with BIS monitoring was found to be associated with better outcomes. BIS monitoring is a guide for adjusting the dosage of sedative agents. It can also minimize agitation, failure of extubation, and length of stay in ICU.

RESUMEN

BACKGROUND: Data on time-based trauma mortality (TTM) patterns in developing countries are lacking. OBJECTIVE: Our objective was to analyze the TTM in a newly established trauma center. METHODS: A retrospective analysis of all trauma-related mortality between 2010 and 2012 was conducted in Qatar. Based on the time of injury, deceased cases were categorized into immediate (pre-hospital), early (first 24 h), and late (>24 h) groups. TTM was analyzed and compared. RESULTS: A total of 4,966 trauma patients were admitted to the trauma center over 3 years; of them, 333 trauma-related deaths (6.8 %) were documented and reviewed. The death pattern peaked immediately post-trauma (n = 142), followed by 96 deaths within the first 24 h, 19 deaths within the time period >24 to 48 h, 50 deaths within the 3rd and 7th day (second peak), and 26 deaths after the 1st week. The majority of the deceased were males, with a mean age of 36 ± 17 years. Motor vehicle crashes (43.5 %) were the commonest mechanism of injury. At presentation, median injury severity score (ISS) was 32 (range 9-75). Bleeding, abdominal, and pelvic injuries were higher in the early group, whereas head injuries were observed more in the late mortality group. Co-morbidities and in-hospital complications were predominantly encountered in the late group. Head injury (odds ratio [OR] 3.760; 95 % confidence interval [CI] 1.311-10.797) was an independent predictor for late death, whereas the need for blood transfusion was a predictor for early death (OR 3.233; 95 % CI 1.125-9.345). CONCLUSION: The distribution of mortality shows a bimodal pattern. The high rate of death at the scene highlights the importance of pre-hospital care and the need for injury prevention programs.
