RESUMEN

BACKGROUND: Attracting and retaining highly qualified applicants to careers in surgery is a goal of residency training programs. Few studies of attrition in residency exist. This study examines the hypothesis that reasons for attrition during general surgery training are different for male and female trainees. MATERIALS AND METHODS: NRMP matching information was used to evaluate attrition rates in a categorical general surgery (CGS) residency program from 1984 through 1996. The records of all matched residents were examined to determine the association between gender and attrition outcomes. Outcome variables included: voluntary vs involuntary withdrawal and the reasons for withdrawal. RESULTS: During the study period 132 candidates matched (103 men and 29 women) into CGS positions. Of that group, 18 residents, 11 (10.7%) from the male and 7 (24.1%) from the female cohorts withdrew. Only three involuntary withdrawals occurred. Women were 2.26 times more likely to withdraw than men, a finding that is not statistically significant (P = 0. 073). Women rarely left for preference of other specialty (relative risk 0.25), whereas men were 4 times more likely to leave for this reason. CONCLUSION: These numbers suggest that women are at higher risk of leaving general surgery training than men. When women do leave, it is more likely for family reasons such as lifestyle considerations or to join a spouse in another geographic location. Such findings support the conclusion that fundamental differences exist in decisions regarding attrition between genders. National studies of attrition and the reasons for leaving are needed to develop specific strategies promoting retention for both genders.

RESUMEN

BACKGROUND: Pancreatic injury is often associated with multiple complications related to uncontrolled pancreatic exocrine secretion, including pancreatic fistula, pseudocyst, and intra-abdominal abscesses. Somatostatin analogues such as octreotide have been shown to decrease pancreas-related morbidity following major pancreatic resection in patients with pancreatic neoplasms and acute severe pancreatitis. This study was conducted to determine whether or not the administration of octreotide influences the incidence and severity of abdominal complications following pancreatic injury. PATIENTS AND METHODS: Patients with intraoperative diagnosis of pancreatic injury over a 6-year period were studied retrospectively. Specific complications assessed include abdominal abscesses, pseudocyst, pancreatitis, and pancreatic fistula. Statistical analysis of qualitative variables was by chi-square analysis, and analysis of quantitative variables by Student's t-test (P < 0.05). RESULTS: Injury to the pancreas was identified in 96 patients. Sixteen early deaths (< 48 hours) and one late death occurred, for a mortality of 18%, leaving 80 patients as the study population; 21 patients received octreotide and 55 patients did not. Pancreatic fistula occurred in 32 patients (40%). When stratified by pancreatic injury severity, there was no significant difference in complication rates, although patients treated with octreotide had a higher rate of fistula formation (48% versus 40%), longer duration of fistula drainage, and longer hospital stay compared with untreated patients. CONCLUSION: Although adverse patient selection may be a factor in this retrospective survey, the magnitude of observed differences raises concerns regarding the empiric administration of octreotide to such patients pending prospective study.

RESUMEN

This article reviews the current status of trauma care education and its relationship to critical care education. The critical linkage of both of these endeavors with urban hospitals oriented to indigent care is stressed. Within the specialty of surgery, the recent progress toward resolution of conflicts that have threatened trauma and critical care education programs is reviewed. The partnership between the trauma programs of urban hospitals will be strengthened by this resolution.

RESUMEN

Injury severity measures are becoming increasingly important for quality assurance and injury research. TRISS analysis, which uses the Revised Trauma Score (RTS) and Injury Severity Score (ISS) to predict survival, is an effective tool for comparing outcomes between trauma centers. It has been argued that blunt trauma outcome differs between children and adults, yet the Major Trauma Outcome Study (MTOS) adult data base (ages 15-54 years) regression weights have been used by others to calculate TRISS scores for injured children. This study appears to be the first to perform TRISS analysis on groups of children and adults treated by the same surgeons using the same treatment protocols to assess the validity of applying "adult" TRISS analysis to children. The charts of 346 consecutive children (ages 0-14) and 346 random adults (ages 15-54) admitted to a regional trauma center for isolated blunt trauma over a 30-month period were reviewed for demographics, mechanism of injury, RTS, ISS, and survival. Statistical evaluation included TRISS survival analysis and calculation of the Z statistic. The median ISS was 10 for both children and adults. The Z statistics for children and adults were similar (1.85 and 1.81). Analysis demonstrated the groups to be statistically identical with a nonsignificant trend toward improved survival compared with the MTOS baseline group. These data support the use of existing TRISS analysis for evaluation of pediatric trauma care.

RESUMEN

A survey of the Washington State Chapter of the American College of Surgeons was undertaken to document the opinions of surgeons on trauma care issues. Thirty-nine percent of the total sample of surgeons who responded would prefer not to treat any trauma patients. These surgeons were more likely to be older, to practice in an urban setting, to feel that trauma call has a negative impact on elective practice, and to believe more strongly that reimbursement from trauma patients is not equal to that of nontrauma patients. They also agreed more strongly with the statements that these patients require a greater time commitment and pose an increased medicolegal risk. The most significant influence on preference not to treat trauma patients was exerted by the perception of a negative impact on practice, older age, and perception of increased medicolegal risk. Reimbursement issues and location of practice were less influential factors. This information can be used to target concerns and barriers to active, willing participation in a trauma care system and to tailor strategies to deal with them effectively.

RESUMEN

This study profiles the practices, experience, and viewpoints of general surgeons treating trauma patients throughout a state. A mail survey of the American College of Surgeons State Chapter membership was conducted. Response rate of general surgeons was 65%. Typically, the trauma surgeon is between 30 and 50 years old, having received formal trauma experience through residency training only. Thirty-nine per cent report current ATLS certification. Practices are most commonly based at a community hospital in an urban setting. Half of surgeons treating trauma operate at more than one hospital and nearly a third take call at more than one hospital simultaneously. Eighty-seven per cent of respondents reported trauma patients comprise less than one quarter of their practice. Most (68%) admitted fewer than 25 trauma patients to their service in the year before the survey and 78% reported performing less than ten trauma laparotomies in the prior year. Fifty-eight per cent disagree that every general surgeon should routinely manage major trauma and 83% feel that traumatology entails a specific body of knowledge and expertise. Of the various components of trauma care, the role of the surgeon in trauma prevention and administrative duties was ranked at least important. The areas of surgeon availability, uniformity of basic experience and adequate maintenance of skills need further analysis.

RESUMEN

Pancreatic injuries are relatively uncommon and usually accompany injuries to major vessels or other gastrointestinal organs. Because it is these associated injuries that are responsible for the early morbidity and mortality, control of hemorrhage and bacterial contamination takes initial priority over the pancreatic injury. The management of specific pancreatic injury depends on the status of the main pancreatic duct, the degree of parenchymal damage, and the anatomic location of the injury. Complete visualization of the gland and accurate determination of the duct status are key intraoperative maneuvers. Failure to recognize significant pancreatic duct and parenchymal injury is the major cause of postoperative morbidity. The vast majority of pancreatic injuries can be managed by simple drainage with or without debridement or suture. However, the occasional major transection or pancreatic duct injury warrants rigorous efforts at determining the status of the major ducts.

RESUMEN

Rupture of the thoracic aorta associated with blunt trauma remains a frequently lethal injury. Although increasing numbers of patients with ruptured aortas are surviving to reach the hospital, the in-hospital mortality attending this injury remains high. Death due to transected aorta has been related to a delay in diagnosis. In an attempt to decrease the time necessary for diagnosis of this injury, we studied 50 patients using intravenous digital subtraction angiography (IVDSA) and conventional biplane angiography. We found that IVDSA was significantly faster than conventional biplane angiography, and that when IVDSA films are of diagnostic quality, they are sufficient to reliably demonstrate the presence of traumatic aortic transection. Our study was too small to establish whether IVDSA is a sufficiently sensitive test to exclude aortic injury. Further studies in this area need to be performed.

RESUMEN

A Pediatric Trauma Score (PTS) was recently developed and is rapidly gaining acceptance as a triage tool. This study examines the utility of the PTS as compared with the Revised Trauma Score, which is applicable to all ages. The charts of 376 children 0 to 14 years of age who were admitted to the trauma service of a level 1 trauma center were reviewed. Significant correlations were found for both the PTS and the Revised Trauma Score with survival, the Injury Severity Score, APACHE II score, vital signs, the Glasgow Coma Scale score, hematocrit, need for an operation, and number of days in an intensive care unit. The PTS was of no statistical advantage as compared with the Revised Trauma Score. Triage accuracy was 68.3% for the PTS and 78.8% for the Revised Trauma Score. The Revised Trauma Score is easy to use and universal in its applicability. The PTS involves learning a separate scoring system and is of no advantage.

RESUMEN

The prehospital, emergency department, and in-hospital care of 84 patients who died following a pedestrian- or bicycle-motor vehicle collision in a four-county area was retrospectively reviewed using a systematic, detailed scoring system. The purpose of the study was to examine the effectiveness of an advanced paramedic-regionalized trauma care system and to examine the usefulness of a systematic evaluation tool in identifying preventable and possibly preventable deaths. Among the 84 deaths, one was judged to be preventable and 18 possibly preventable. The one preventable death occurred in the emergency department, while the possibly preventable deaths more commonly occurred after 48 hours and were due to central nervous system injury, sepsis, and multiple organ failure. Prolonged prehospital and emergency department time and failure to establish an airway were the most common problems identified as contributing to fatal outcome. The use of explicit criteria was demonstrated to be an effective addition to the analysis of trauma care systems.

RESUMEN

Clotting factor activities and coagulation screening tests in 36 massively transfused patients were measured after every 12 units of blood and whenever diffuse microvascular bleeding (MVB) developed. Moderate deficiencies in clotting factors were common, but they were not associated with MVB. MVB was associated with severe abnormalities of coagulation, i.e. a fibrinogen level less than 0.5 g/l or clotting factor levels less than 20%. The quantitative relationship between the prothrombin (PT) and partial thromboplastin (PTT) times and underlying clotting factor levels was explored by multiple linear regression. Clotting factor levels accounted for only 65-85% of the variability in these tests. However, clotting factor activities less than 20% were reliably reflected by marked prolongations of the PT and PTT (values greater than 1.8 times control). Our data suggest that commonly used replacement formulas are not likely to prevent MVB, since consumption of platelets and/or clotting factors, rather than simple dilution, is a major cause of the deficiencies leading to MVB. Modified whole blood alone was sufficient replacement therapy for most patients. Guidelines for transfusion of supplemental components during massive transfusion are given.

RESUMEN

The effects of selectively inhibiting synthesis of thromboxane A2 (TXA2) with dazoxiben and of all cyclooxygenase products with indomethacin were studied in goats after infusion of 5 X 10(8) live Escherichia coli bacteria/kg. Pulmonary and systemic pressures, cardiac output, and double indicator dilution extravascular lung water (EVLW) were measured at 15-min intervals. EVLW was determined gravimetrically at 6 hr to confirm the final double indicator dilution values. Plasma levels of TXA2 and prostacyclin (PGI2) were measured as their stable metabolites, TXB2 and 6-keto-PGF1 alpha, respectively. Dazoxiben blocked the increase in plasma TXB2, prevented pulmonary hypertension, and attenuated the increase in EVLW after E. coli. Mean gravimetric EVLW was 8.7 ml/kg in the dazoxiben-treated group compared to 11.3 ml/kg in the untreated control group. Indomethacin blocked the increased plasma TXB2 and 6-keto-PGF1 alpha, attenuated pulmonary hypertension, and prevented almost all increases in EVLW. Mean gravimetric EVLW was 8.2 ml/kg after indomethacin. We conclude that in acute bacteremia, the early pulmonary hypertension is mediated largely by TXA2 (however, a second phase of hypertension results from non-cyclooxygenase products), either production of cyclooxygenase products (perhaps PGI2) inhibits part of the action of pulmonary vasoconstrictors, or indomethacin stimulates the production of other vasoconstrictors (such as lipoxygenase products), and indomethacin prevents the accumulation of EVLW by blocking formation of cyclooxygenase products or by other nonspecific actions.

RESUMEN

In an 18-month period candidal splenic abscesses were diagnosed and treated in eight patients. Predisposing factors consisted of recent exposure to cytotoxic chemotherapy, long-term use of prednisone, neutropenia, antibiotic therapy for greater than three weeks, and gastrointestinal tract colonization with Candida. The patients had a clinical profile of nontoxic appearance with a temperature of more than 38.5 degrees C that was unresponsive to antibiotics, pain and tenderness over the upper abdominal quadrants, focal defects visualized on ultrasound and/or computed tomographic scans, and an elevated alkaline phosphatase level. Candida infection was confirmed by histologic examination of the liver and/or spleen in all patients. Diagnosis was made by percutaneous biopsy in one patient and exploratory laparotomy in seven. Five patients had splenectomy and antifungal drugs. In three patients the fungal abscesses resolved with amphotericin B therapy alone. Seven of eight patients were cured of their splenic abscesses, and five of eight were long-term survivors.

RESUMEN

Despite the fact that many new exciting prospects are on the horizon, volume support remains the cornerstone of resuscitation of the critically ill surgical patient. Their limitations not withstanding, balanced electrolyte solutions, properly used, are the most efficacious choice in the majority of patients. The patient's eventual survival depends not only on skillful resuscitation but on the ability to identify and correct the underlying cause.

RESUMEN

Prior studies at Harborview Medical Center have suggested that dilutional thrombocytopenia is a major etiology of microvascular, nonmechanical bleeding (MVB). We undertook a prospective randomized double-blind clinical study to compare the prophylactic effects of 6 units of platelet concentrates (PLT) versus 2 units of fresh frozen plasma (FFP) administered with every 12 units of modified whole blood in patients undergoing massive transfusion (12 or more units in 12 hours). After exclusions, three of 17 patients who received PLT and three of 16 patients who received FFP developed MVB, an incidence no different from our previous findings. Regression lines of platelet counts during transfusion were no different between groups, and both groups had higher platelet counts than predicted from a standard washout equation. Only one patient had evidence of dilutional thrombocytopenia as a cause for MVB. Prophylactic platelet administration is not warranted as a routine measure to prevent MVB.
