RESUMEN
Background and objective: Abdominal surgery stands as one of the most frequently conducted procedures across surgical specialties, accounting for up to half of surgery-related expenses. Hemodynamic instability emerges as a significant concern during anaesthesia and surgery, provoked by the stress of intubation, surgical incision, and anaesthetic agents. Following abdominal surgery, pain is an inevitable consequence, typically managed with opioid-based analgesia. However, the adverse effects associated with opioids often overshadow their analgesic benefits, particularly in the context of abdominal surgery. Consequently, there exists a necessity to explore and assess alternative non-opioid pain management options post-abdominal surgery as part of a broader strategy to reduce opioid usage. The primary aim of this investigation is to assess the effectiveness of varying doses of dexmedetomidine in regulating intraoperative hemodynamics and alleviating postoperative pain in patients undergoing abdominal surgery. Methods: Ethical clearance and institutional review board were obtained from the ethical clearance committee of Dilla University College of Medicine and Health Sciences with protocol unique number of duirb/008/22-01. Our trial has been prospectively registered on the Pan African Clinical Trial Registry with a unique identification number for the registry PACTR202208813896934. Statistical package and analysis were performed by using SPSS version 25. The distribution of data was checked by using Shapiro-Wilk test and the homogeneity of variance was checked by Levene's test. Analysis of variance (ANOVA) and Kruskal-Wallis H test were used for normally distributed continuous data and non-normally distributed or non-parametric data, respectively. P value less than 0.05 with a power of 90% was considered statistically significant. Result: There was a statistically significant increase in mean SBP in the control group at the different critical time points (P<0.05), as compared to the baseline value, while there was no significant difference in mean systolic blood pressure (SBP) between the baseline and all other levels for group 2 and group 3. A statistically significant increase in mean arterial pressure (MAP) was detected in the control group at immediately after intubation (P=0.009) as compared to the baseline value, while a statistically significant reduction in mean heart rate (HR) was observed in group 3 at 15th min after infusion and at 30th 30 min after induction compared to baseline with a P value of 0.002 and 0.008, respectively.Conclusion:Perioperative low-dose infusion of dexmedetomidine at the rate of 0.4 mcg/kg/h is a useful anaesthesia adjuvant to control hemodynamic stress response to critical periods. It is wise to use this infusion dose as part of general anaesthesia to achieve better hemodynamic stability.
RESUMEN
BACKGROUND: Previous Ethiopian literature on surgical capacity and challenges has focused on quantitative investigations, lacking contextual understanding. This explanatory sequential mixed-methods research (MMR) aimed to assess perioperative capacity and contextual challenges at three teaching hospitals in southern Ethiopia. METHODS: A quantitative survey assessed workforce, infrastructure, service delivery, financing, and information systems. The survey findings were explained by qualitative semi-structured interviews of twenty perioperative providers. Descriptive statistics were integrated with qualitative thematic analysis findings using the narrative waving approach. Key findings from both datasets were linked using a joint display table. RESULTS: The survey revealed shortages in the specialist workforce (with a ratio of 0.58 per 100,000 population), surgical volume (at 115 surgeries per 100,000 population), equipment, supplies, financing, and perioperative data tracking. Hospitals' radiology services and blood products were only available 25-50% of the time, while anesthetic agents and essential laboratory services were often available 51-75% of the time. Perioperative management protocols were used rarely (1-25% of the time). Over 90% of patients lack health insurance coverage. Qualitative data also revealed scarcity of perioperative resources and equipment; unaffordable perioperative costs, lack of health insurance coverage, and unforeseen expenses; poor patient safety culture and communication barriers across the perioperative continuum of care; workforce shortages, job dissatisfaction, and concerns of competence; and weak national governance, and sociopolitical turmoil, and global market volatility exacerbating local challenges. These challenges are linked to risks in quality of care and patient safety, according to clinicians. CONCLUSION: The study identifies deficiencies in the health system and sociopolitical landscape affecting safe surgery conduct. It highlights the need for comprehensive health system strengthening to expand workforce, upgrade facilities, improve safety culture, resilience, and leadership to ensure timely access to essential surgery. Exploring external factors, such as the impact of national governance and sociopolitical stability on reform efforts is also essential.
RESUMEN
Background: The analgesic effectiveness of a single perioperative dose of dexamethasone is not clearly defined. The administration of systemic medication like dexamethasone, opioids, and non-steroidal anti-inflammatory drugs has a positive effect on the prolongation of postoperative analgesia after cesarean section under spinal anesthesia. A single-dose administration of dexamethasone with moderate to high dose reduces postoperative pain, reduces opioid consumption, and prolongs spinal anesthesia after cesarean delivery. Objective: The aim of this systematic review was to investigate the effectiveness of single intravenous dexamethasone in prolongation of spinal anesthesia for postoperative analgesia in elective cesarean section. Methods: We conducted a search on PubMed, Google Scholar, the Cochrane Library, Hinari, and review articles on the effectiveness of intravenous dexamethasone for extending spinal anesthesia during elective cesarean sections, until June 2023. The searches were conducted by using keyword (IV dexamethasone OR/AND analgesia OR postoperative pain AND cesarean section OR child birth AND prolongation of spinal anesthesia). The articles included describe the analgesic efficacy of dexamethasone for prolongation of spinal anesthesia during cesarean section. Results: A total of 25,384 papers were found using different searching methodologies from different electronic databases. The EndNote reference manager was used to remove duplicates, and 438 articles were selected for screening. Of those, 57 were included for critical evaluation, and 49 were removed with justification. The effectiveness of IV dexamethasone on the prolongation of spinal anesthesia and postoperative analgesia in women undergoing cesarean delivery is the subject of eight RCT studies on 628 parturients that are presented in the chosen journal articles from various countries. Conclusion: Intravenous dexamethasone administration immediately after clamping of the umbilical cord prolongs the duration of spinal block in patients undergoing cesarean sections and has a significant impact on reduction of postoperative pain severity, opioid consumption, and other pain requirements. When high-dose dexamethasone is administered intravenously, it can overcome complications that may arise after severe pain and increase patient satisfaction by extending the duration of postoperative analgesia and sensory block.
RESUMEN
Background: Cesarean section (CS) is a surgical procedure where the baby is delivered through incisions made in the abdomen and uterus. Bupivacaine is a widely recognized local anesthetic available in different baricity and it is frequently used for spinal anesthesia. The baricity of bupivacaine impacts hemodynamic profiles and block characteristics. Objective: To compare the effects of hyperbaric and isobaric bupivacaine on hemodynamic profiles and block characteristics among parturients undergoing elective cesarean section under spinal anesthesia at Dilla University Referral Hospital. Methods: 64 pregnant mothers scheduled for elective cesarean section under spinal anesthesia were randomly assigned to two groups: Group A received a dose of 12.5 mg of isobaric bupivacaine (n = 32), Group B received a dose of 12.5 mg of hyperbaric bupivacaine (n = 32). Prior to conducting the study, the necessary ethical approvals were obtained. For comparing numerical variables between the two groups, the independent Sample t-test or Mann-Whitney U-test was employed as needed. Repeated measurements were analyzed using mixed ANOVA. Categorical variables were assessed using either the chi-square test or Fisher's exact test. Statistical significance was set at P < 0.05, with a power of 90%. Results: The mean Systolic Blood Pressure (SBP), Diastolic Blood pressure (DBP), and Mean Arterial Blood Pressure (MAP) showed significant decrement in the group receiving isobaric spinal anesthesia compared to those receiving hyperbaric bupivacaine. The decrement was observed from the 6th to 30th minute (p<0.05). Furthermore, the hyperbaric group had a faster onset time for achieving the maximum sensory block, with a median time of 3 (1) min compared to 4 (2) mins in the isobaric group (p<0.001). Conclusion and Recommendation: We conclude that hyperbaric bupivacaine provides stable intraoperative hemodynamic parameters and an earlier onset of block than isobaric bupivacaine. Therefore, we recommend clinicians to use hyperbaric bupivacaine for cesarean delivery.
RESUMEN
Status epilepticus (SE) is a life-threatening condition associated with at least 5 min of continuous seizures or repeated seizures without regaining consciousness between episodes. It is a medical emergency with significant morbidity and mortality. The most common causes of SE are previous seizures, stroke, trauma, metabolic disorders, and central nervous system tumor. The aim of this review was to systematically review articles and ultimately develop evidence-based guidelines for the management of SE in resource-limited settings. Methods: This review was presented under the Protocol for Systematic Reviews and Meta-Analyses (PRISMA). A literature search was performed in PubMed, Google Scholar, Cochrane, and Medline databases from 2007 to 2021. The keywords for the literature search were (SE or controlled clinical trial) AND (SE or randomized controlled trial), (SE or multicenter trial) AND (SE or meta-analysis) AND (SE or crossover study). Conclusion: SE is an urgent medical emergency that requires early recognition and aggressive treatment. Medical treatment is initiated when seizures continue for more than 5 min after all stabilization measures have been taken. Based on the available evidence, diazepam can be used as a substitute for lorazepam in the treatment of SE. Ketamine is effective when given before other anesthetics as a third-line treatment in refractory and very refractory epilepsy. Propofol reduced the number of days of mechanical ventilation in the treatment of SE and has better seizure control than thiopental. Music has been recommended as an adjunctive therapy for epilepsy medication.
RESUMEN
Background: Postoperative sore throat is one of the common postoperative complications following general anesthesia. Postoperative sore throat causes decreased patient satisfaction, and it affects patients' well-being after surgery, thus identifying its incidence and predictors helps to distinguish the preventable causes of postoperative sore throat. This study aimed to assess the incidence and associated factors of postoperative sore throat among pediatric patients undergoing surgery under general anesthesia at Hawassa university comprehensive specialized hospital. Methods: A prospective cohort study was conducted among children in the age range 6-16 years old who underwent emergency and elective surgical procedures under general anesthesia. Data were entered and analyzed using SPSS version 26 software packages. Univariate and multivariate analyses were performed to investigate the independent predictors. The presence and severity of postoperative sore throat were assessed by using a four-point categorical pain scale at the 2nd, 6th, 12th, and 24th-hour postoperative time. Results: A total of 102 children were recruited in this study, from which 27 children (26.5%) complained of sore throat postoperatively. This study found that endotracheal intubation (P value: 0.030; AOR: 3.155; 95% CI [1.114-8.933]) and several attempts greater than one (P value: 0.027 and AOR: 4.890; 95% CI: [1.203-19.883]) had statistically significant association with a postoperative sore throat. Conclusion: The overall incidence of postoperative sore throat was 26.5%. Endotracheal intubation and the number of attempts greater than one were independent factors that were significantly associated with the occurrence of postoperative sore throat in this study.
