RESUMO
INTRODUCTION: Trauma centre capacity and surge volume may affect decisions on where to transport a critically injured patient and whether to bypass the closest facility. Our hypothesis was that overcrowding and high patient acuity would contribute to increase the mortality risk for incoming admissions. METHODS: For a 6-year period, we merged and cross-correlated our institutional trauma registry with a database on Trauma Resuscitation Unit (TRU) patient admissions, movement and discharges, with average capacity of 12 trauma bays. The outcomes of overall hospital and 24 hours mortality for new trauma admissions (NEW) were assessed by multivariate logistic regression. RESULTS: There were 42 003 (mean=7000/year) admissions having complete data sets, with 36 354 (87%) patients who were primary trauma admissions, age ≥18 and survival ≥15 min. In the logistic regression model for the entire cohort, NEW admission hospital mortality was only associated with NEW admission age and prehospital Glasgow Coma Scale (GCS) and Shock Index (SI) (all p<0.05). When TRU occupancy reached ≥16 patients, the factors associated with increased NEW admission hospital mortality were existing patients (TRU >1 hour) with SI ≥0.9, recent admissions (TRU ≤1 hour) with age ≥65, NEW admission age and prehospital GCS and SI (all p<0.05). CONCLUSION: The mortality of incoming patients is not impacted by routine trauma centre overcapacity. In conditions of severe overcrowding, the number of admitted patients with shock physiology and a recent surge of elderly/debilitated patients may influence the mortality risk of a new trauma admission.

RESUMO
Acute calculus cholecystitis is a very common disease with several area of uncertainty. The World Society of Emergency Surgery developed extensive guidelines in order to cover grey areas. The diagnostic criteria, the antimicrobial therapy, the evaluation of associated common bile duct stones, the identification of "high risk" patients, the surgical timing, the type of surgery, and the alternatives to surgery are discussed. Moreover the algorithm is proposed: as soon as diagnosis is made and after the evaluation of choledocholitiasis risk, laparoscopic cholecystectomy should be offered to all patients exception of those with high risk of morbidity or mortality. These Guidelines must be considered as an adjunctive tool for decision but they are not substitute of the clinical judgement for the individual patient.
RESUMO
PURPOSE: Though primary repair of colon injuries is preferred, certain injury patterns require colostomy creation. Colostomy reversal is associated with significant morbidity and healthcare cost. Complication rates may be influenced by technique of diversion (loop vs. end colostomy), though this remains ill-defined. We hypothesized that reversal of loop colostomies is associated with fewer complications than end colostomies. METHODS: This is a retrospective, multi-institutional study (four, level-1 trauma centers) of patients undergoing colostomy takedown for trauma during the time period 1/2006-12/2012. Data were collected from index trauma admission and subsequent admission for reversal and included demographics and complications of reversal. Student's t test was used to compare continuous variables against loop versus end colostomy. Discrete variables were compared against both groups using Chi-squared tests. RESULTS: Over the 6-year study period, 218 patients underwent colostomy takedown after trauma with a mean age of 30; 190 (87%) were male, 162 (74%) had penetrating injury as their indication for colostomy, and 98 (45%) experienced at least one complication. Patients in the end colostomy group (n = 160) were more likely to require midline laparotomy (145 vs. 18, p < 0.001), had greater intra-operative blood loss (260.7 vs. 99.4 mL, p < 0.001), had greater hospital length of stay (8.4 vs. 5.5 days, p < 0.001), and had more overall complications (81 vs. 17, p = 0.005) than patients managed with loop colostomy (n = 58). CONCLUSIONS: Local takedown of a loop colostomy is safe and leads to shorter hospital stays, less intra-operative blood loss, and fewer complications when compared to end colostomy.

The hemodynamically unstable patient with a pelvic fracture presents a diagnostic and therapeutic challenge. The care of these patients requires a unique multidisciplinary approach with input and expertise from many different specialists. An understanding of pelvic anatomy and fracture patterns can help guide the diagnostic evaluation and treatment plan. The initial management of these patients must focus on rapid airway and hemorrhage control while preparing for ongoing blood loss. Rapid temporary fracture stabilization with simple bedside modalities is crucial in limiting additional blood loss. An exhaustive search must also be performed to evaluate for concomitant injuries that commonly accompany major pelvic fractures and the treatment of these other injuries must be appropriately prioritized. For patients who are unresponsive to standard resuscitation and bedside attempts at limiting hemorrhage, angiographic embolization is often utilized as the next step to attain hemodynamic stability. The key to successful management of these patients lies in the careful coordination of different specialists and the expertise that each brings to the clinical care of the patient.

BACKGROUND: To analyze the use of admission angiography as a nonoperative adjunct for management of blunt splenic injury. METHODS: Retrospective chart review of all blunt splenic injuries to a Level I trauma center from March 1997 through July 1999. RESULTS: One hundred twenty-six patients underwent angiography for splenic injury. Eighty-six patients (68%) had a negative angiogram and were treated expectantly. Of these, seven patients (8%) required laparotomy, with a splenic salvage rate of 92%. Embolization was performed on 40 patients (32%) for evidence of vascular injury. Of these, three patients (8%) required laparotomy, for a total salvage of 92%. Repeat angiography was performed for suspicion of bleeding in 12 patients (10%), with 50% requiring embolization. Outcome based on CT grade demonstrated an average grade of 2.9, with a salvage rate of greater than 70% for grade IV and V injuries. CONCLUSION: Vascular injury increases with splenic injury grade. Embolization improves nonoperative salvage rates to 92%, even with high-grade injuries. Ten percent of patients require additional therapy including "second-look" angiography. A significant portion of patients with negative screening angiograms (10%) required either embolization or laparotomy to control delayed hemorrhage.

Several reports over the past decade have suggested that there has been an increase in the number of invasive streptococcal infections with young children and the elderly being at the highest risk. We evaluated the incidence of group A Streptococcus (GAS) and compared it with historic data collected at our institution. Prospective data were collected on patients diagnosed with GAS (with and without shock) admitted to a tertiary-care center from July 1995 to July 2000. Each patient was followed by an infectious disease specialist throughout the hospital stay. Definitions of streptococcal toxic shock syndrome (STSS) developed by the Centers for Disease Control and Prevention were used. Thirty-eight patients (mean age of 39+/-12) presenting with GAS soft-tissue infections were admitted to our institution over a 5-year period (7.6 patients per year). Fourteen (37%) were diagnosed with STSS. This represents a greater than fourfold increase in the average number of cases per year of patients diagnosed with GAS and a nearly 4.5 times greater increase in the annual number of patients diagnosed with STSS. The overall mortality of patients diagnosed with GAS was 13 per cent, which increased to 36 per cent in patients diagnosed with STSS. We conclude that there has been a significant increase in the incidence of GAS soft-tissue infections over the past 5 years at our institution. This may represent a new virulent strain, as the majority of these infections did not occur in typical high-risk patients at the extremes of their lives. Further epidemiologic population-based studies are needed to further delineate the severe nature of this problem.

BACKGROUND: Spiral computed tomographic (CT) scan is an excellent screen for aortic trauma. Traditionally, aortography is performed when injury is suspected to confirm the diagnosis. We hypothesized that it is safe and expeditious to forgo aortography when the spiral CT demonstrates aortic injury. METHODS: Retrospective review of 54 patients undergoing aortic repair from July 1994 to December 1999. Spiral CT was the initial diagnostic study in 52 patients. Pseudoaneurysm or aortic wall defect in the presence of mediastinal hematoma was considered diagnostic. Angiography, initially routine, was later performed only when requested by the surgeon, and for all "nonnegative" studies (periaortic hematoma without detectable aortic injury). RESULTS: Twenty-six patients underwent angiography before operation (group 1). Nineteen group 1 spiral CTs were unequivocally diagnostic; 7 were nonnegative and angiography was required. Twenty-eight other patients underwent repair based on spiral CT alone (group 2). There was one false-positive result in both groups. There were no unexpected operative findings. Mean time from admission to diagnosis was 5.7+/-3.4 hours for group 1 and 1.7+/-1.7 hours for group 2 (p < 0.01). CONCLUSIONS: Operating on the basis of a diagnostic spiral CT is safe and expeditious. Aortography may be reserved for those with equivocal studies.

BACKGROUND: The rate of incidental pregnancy in trauma patients and the incidence of associated fetal mortality, to our knowledge, have not been previously reported. The early diagnosis of pregnancy in trauma patients has become even more difficult because rapid pregnancy screens have been eliminated because of quality control issues. We determined the rate of incidental pregnancy and the sequelae of delayed diagnosis, including fetal radiation exposure and mortality. STUDY DESIGN: Data were analyzed retrospectively on all patients in whom pregnancy was diagnosed during a trauma admission during a 4-year period (1995 to 1999). Pregnancy was confirmed by beta-HCG testing and gestational age estimated by an obstetrician by ultrasonography. Pregnancy outcomes were determined by a prospective telephone survey. RESULTS: One hundred fourteen (2.9%) of the 3,976 women (age 15 to 40 years) admitted to the trauma center were found to be pregnant. Thirteen (11.0%) were incidental pregnancies, of which 9 (8.0%) were newly diagnosed. Mean gestational age was significantly lower in the newly diagnosed pregnancies (6.9 versus 20.5 weeks, p < 0.0005). Fetal mortality in this group was significantly higher (100% versus 25%, p < 0.0005). The mean initial radiation exposure of all patients was 4.5 rads. Cumulative radiation exposure exceeded 5 rads in 85% of patients. CONCLUSIONS: Trauma patients diagnosed with incidental pregnancy are routinely exposed to doses of radiation exceeding the recommendations of the American College of Obstetrics and Gynecologists. Reinstitution of the rapid pregnancy test should be considered in all female trauma victims of childbearing age. This may promote a reduction in fetal radiation exposure and perhaps influence a portion of the fetal mortality in those patients with newly diagnosed incidental pregnancy.

BACKGROUND: Cytokines signal the normal processes of inflammation and repair in all organs, yet the aberrant expression of these peptide mediators is associated with significant organ dysfunction. The accurate measurement of cytokines is therefore critical. In this study, we sought to investigate the alterations in cytokine expression early after trauma in humans using a new competitive binding immunoassay that measures both free and bound cytokine and compare this with standard enzyme-linked immunosorbent assay (ELISA), which measures only free cytokine. METHODS: Peripheral blood was obtained from trauma patients at admission. Exclusion criteria were transfers, death within 24 hours, pregnancy, known acquired immunodeficiency syndrome, chemotherapy, transplant, or other chronic immune disorder. "Total" cytokine immunoassay was compared with ELISA for cytokines (interleukin [IL]-1, IL-6, and IL-10) measured in serum. RESULTS: Cytokine concentrations measured by total immunoassay were significantly higher (10- to 500-fold increase) than those measured by ELISA, and correlation between the two methods was poor (r2 = 0.193 for IL-10). No significant differences in mean serum cytokine concentrations were noted between trauma patients and normal controls for IL-1 (56 vs. 37 pg/mL), IL-6 (16 vs. 25 pg/mL), and IL-10 (4 vs. 26 pg/mL) using the ELISA method. In contrast, trauma patients had significantly higher serum concentrations of IL-1 (3,320 vs. 1,470 pg/mL, p < 0.05), IL-6 (2,415 vs. 1,048 pg/mL, p < 0.05), and IL-10 (2,307 vs. 1,480 pg/mL, p < 0.05) at admission compared with normal controls using total cytokine immunoassays. CONCLUSION: Cytokine measurements in peripheral blood in trauma patients and normal controls are significantly (10- to 500-fold) higher when using a total cytokine assay that measures both free and bound cytokine. Competitive immunoassays may be the method of choice when measuring endogenous cytokine levels in biologic fluids, and new normal ranges for cytokines must be established for future accurate research in critical care and trauma.

BACKGROUND: The potential for ligamentous injury of the cervical spine (C-spine) may mandate prolonged neck immobilization via a hard cervical collar in the blunt trauma victim (BTV) with altered sensorium. We investigated the incidence of ligamentous C-spine injuries, and whether applying (post hoc) the practice management guidelines from the Eastern Association for the Surgery of Trauma (three radiograph views plus computed tomographic scan of C1-C2) would have detected the injuries. METHODS: The study was a 3-year retrospective review of BTVs admitted to the state's Primary Adult Resource Center for trauma from 1996 to 1998. Unreliable patients were defined as those with admission Glasgow Coma Scale score < 15. A rigorous algorithm to clear the C-spine was used. Pure ligamentous C-spine injury was defined as a C-spine having abnormal anatomic alignment, dislocation, subluxation, or listhesis, but without fracture. Demographics, diagnostic studies, presence of neurologic deficit, therapy, survival, and disposition were analyzed. RESULTS: There were 14,577 BTVs with 614 (4.2%) patients having C-spine injury. There were 2,605 (18%) unreliable patients, with 143 (5.5%) of these having C-spine injury, 129 (90%) having fracture and 14 (10% of BTVs; 0.5% of unreliable patients) having no fracture. Of the 14 unreliable patients with pure ligamentous C-spine injury, 13 had initial diagnosis by supine cross-table lateral radiograph. The one exception had a normal three-view radiographic series, but atlanto-occipital dislocation was diagnosed by computed tomographic scan. Eight patients had upper level injury (C0-C4) and six were lower (C4-C7). Four patients died within 30 minutes after admission, 4 underwent cervical fusion, and 6 were treated with collar only. Five (50%) of the survivors had no apparent neurologic deficit attributed to the C-spine at admission. Nine patients remained institutionalized after discharge and one was discharged home. CONCLUSION: Ligamentous injuries without fracture of the C-spine are rare. Application of the practice management guidelines developed by the Eastern Association for the Surgery of Trauma for identifying C-spine instability is effective and should facilitate early removal of the cervical collar in unreliable patients.

BACKGROUND: Previous studies have suggested that patients transported by emergency medical services (EMS) following major trauma had a longer injury-to-treatment interval and a higher mortality rate than their non-EMS-transported counterparts. HYPOTHESIS: There is little actual benefit of thoracolumbar immobilization for patients with torso gunshot wounds (GSW). DESIGN: Retrospective analysis of prospectively gathered data from the Maryland Institute for Emergency Medical Service Systems State Trauma Registry from July 1, 1995, through June 30, 1998. SETTINGS: All designated trauma centers in Maryland. PATIENTS: All patients with torso GSW. MAIN OUTCOME MEASURES: (1) A patient was considered to have benefited from immobilization if he or she had less than complete neurologic deficits in the presence of an unstable vertebral column, as shown by the need for operative stabilization of the vertebral column; (2) mortality. RESULTS: There were 1000 patients with torso GSW. Among them, 141 patients (14.1%) had vertebral column and/or spinal cord injuries. Two patients (0.2%) (95% confidence interval, -0.077% to 0.48%) required operative vertebral column stabilization, while 6 others required other spinal operations for decompression and/or foreign body removal. The presence of vertebral column injury was actually associated with lower mortality (7.1% vs 14.8%, P<.02). CONCLUSIONS: This study suggests that thoracolumbar immobilization is almost never beneficial in patients with torso GSW, and that a higher mortality rate existed among those GSW patients without vertebral column injury vs those with such injuries. The role of formal thoracolumbar immobilization for patients with torso GSW should be reexamined.

PURPOSE: To determine if contrast material-enhanced spiral computed tomography (CT) can be used to select patients with blunt splenic injuries to undergo arteriographic embolization. MATERIALS AND METHODS: During a 15-month period, 78 patients who were hemodynamically stable and required no immediate surgery underwent contrast-enhanced spiral CT followed by splenic arteriography. CT scans were assessed for splenic vascular contrast material extravasation or posttraumatic splenic vascular lesions. Medical records were reviewed for splenic arteriographic results and clinical outcome. RESULTS: There were 25 grade I, 12 grade II, 27 grade III, 12 grade IV, and two grade V splenic injuries. CT showed active contrast material extravasation in seven patients and splenic vascular lesions in 19 patients. At CT, splenic vascular contrast material extravasation was 100% (seven of seven patients) and a posttraumatic splenic vascular lesion was 83% (10 of 12 patients) sensitive on the basis of arteriographic or surgical outcome in predicting the need for transcatheter embolization or splenic surgery. Overall, CT had a sensitivity of 81% (17 of 21 patients), a specificity of 84% (48 of 57 patients), negative and positive predictive values of 92% (48 of 52 patients) and 65% (17 of 26 patients), respectively, and an accuracy of 83% (65 of 78 patients) in predicting the need for splenic injury treatment. CONCLUSION: Contrast-enhanced spiral CT plays a valuable role in selecting hemodynamically stable patients with splenic vascular injury who may be treated with transcatheter therapy and potentially improves the success rate of nonsurgical management.

The objective of this study was to discuss the case of a patient with severe smoke inhalation-related respiratory failure treated with extracorporeal support. The study was set in a 12-bed multi-trauma intensive care unit at a level one trauma center and hyperbaric medicine center. The patient under investigation had carbon monoxide poisoning, and developed acute respiratory distress syndrome and cardiovascular collapse following smoke inhalation. Rapid initiation of extracorporeal support, extreme inverse-ratio ventilation and intermittent prone positioning therapy were carried out. Admission and serial carboxyhemoglobin levels, blood gases, and computerized tomography of the chest were obtained. The patient developed severe hypoxia and progressed to cardiovascular collapse resistant to resuscitation and vasoactive infusions. Veno-venous extracorporeal support was initiated. Cardiovascular parameters of blood pressure, cardiac output, and oxygen delivery were maximized; oxygenation and ventilation were supported via the extracorporeal circuit. Airway pressure release ventilation and intermittent prone positioning therapy were instituted. Following 7 days of extracorporeal support, the patient was decannulated and subsequently discharged to a transitional care facility,neurologically intact. Smoke inhalation and carbon monoxide poisoning may lead to life-threatening hypoxemia associated with resultant cardiovascular instability. When oxygenation and ventilation cannot be achieved via maximal ventilatory management, extracorporeal support may prevent death if initiated rapidly.

BACKGROUND: The advantages of early fracture fixation in patients with multiple injuries have been challenged recently, particularly in patients with head injury. External fixation (EF) has been used to stabilize pelvic fractures after multiple injury. It potentially offers similar benefits to intramedullary nail (IMN) in long-bone fractures and may obviate some of the risks. We report on the use of EF as a temporary fracture fixation in a group of patients with multiple injuries and with femoral shaft fractures. METHODS: Retrospective review of charts and registry data of patients admitted to our Level 1 trauma center July of 1995 to June of 1998. Forty-three patients initially treated with EF of the femur were compared to 284 patients treated with primary IMN of the femur. RESULTS: Patients treated with EF had more severe injuries with significantly higher Injury Severity Scores (26.8 vs. 16.8) and required significantly more fluid (11.9 vs. 6.2 liters) and blood (1.5 vs. 1.0 liters) in the initial 24 hours. Glasgow Coma Scale score was lower (p < 0.01) in those treated with EF (11 vs. 14.2). Twelve patients (28%) had head injuries severe enough to require intracranial pressure monitoring. All 12 required therapy for intracranial pressure control with mannitol (100%), barbiturates (75%), and/or hyperventilation (75%). Most patients had more than one contraindication to IMN, including head injury in 46% of cases, hemodynamic instability in 65%, thoracoabdominal injuries in 51%, and/or other serious injuries in 46%, most often multiple orthopedic injuries. Median operating room time for EF was 35 minutes with estimated blood loss of 90 mL. IMN was performed in 35 of 43 patients at a mean of 4.8 days after EF. Median operating room time for IMN was 135 minutes with an estimated blood loss of 400 mL. One patient died before IMN. One other patient with a mangled extremity was treated with amputation after EF. There was one complication of EF, i.e., bleeding around a pin site, which was self-limited. Four patients in the EF group died, three from head injuries and one from acute organ failure. No death was secondary to the fracture treatment selected. One patient who had EF followed by IMN had bone infection and another had acute hardware failure. CONCLUSION: EF is a viable alternative to attain temporary rigid stabilization in patients with multiple injuries. It is rapid, causes negligible blood loss, and can be followed by IMN when the patient is stabilized. There were minimal orthopedic complications.

HYPOTHESIS: Factors associated with fetal death in injured pregnant patients are related to increasing injury severity and abnormal maternal physiologic profile. DESIGN: A multi-institutional retrospective study of 13 level I and level II trauma centers from 1992 to 1996. MAIN OUTCOME MEASURE: Fetal survival. RESULTS: Of 27,715 female admissions, there were 372 injured pregnant patients (1.3%); 84% had blunt injuries and 16% had penetrating injuries. There were 14 maternal deaths (3.8%) and 35 fetal deaths (9.4%). The population suffering fetal death had higher injury severity scores (P<.001), lower Glascow Coma Scale scores (P<.001), and lower admitting maternal pH (P = .002). Most women who lost their fetus arrived in shock (P = .005) or had a fetal heart rate of less than 110 beats/min at some time during their hospitalization (P<.001). An Injury Severity Score greater than 25 was associated with a 50% incidence of fetal death. Placental abruption was the most frequent complication, occurring in 3.5% of patients and associated with 54% mortality. Cardiotrophic monitoring to detect potentially threatening fetal heart rates was performed on only 61% of pregnant women in their third trimester. Of these patients, 7 had abnormalities on cardiotrophic monitoring and underwent successful cesarean delivery. CONCLUSIONS: Fetal death was more likely with greater severity of injury. Cardiotrophic monitoring is underused in injured pregnant patients in their third trimester even after admission to major trauma centers. Increased use of cardiotrophic monitoring may decrease the mortality caused by placental abruption.

BACKGROUND: Techniques for placement of inferior vena cava (IVC) filters have undergone continued evolution from open surgical exposure of the venous insertion site to percutaneous insertion in most cases today. However, the required transport either to an operating room or interventional suite can be complex and potentially hazardous for the multiply injured trauma patient who may require ventilator support, controlled intravenous infusions, or skeletal immobilization. Increased experience with color-flow duplex scanning for routine IVC imaging and portability of ultrasound equipment have suggested the usefulness of duplex-guided IVC filter insertion (DGFI) in critically ill trauma and intensive care unit (ICU) patients. METHODS: A total of 25 multitrauma/ICU patients were considered for DGIF. Screening color-flow duplex scans were performed on all patients, and obesity or bowel gas prevented ultrasound imaging in 2 cases, leaving 23 patients suitable for DGFI. In each case, the IVC was imaged in the transverse and longitudinal planes. The right renal artery was identified as it passed posterior to the IVC and was used as a landmark of the infrarenal segment of the IVC. All procedures were performed at the bedside in a monitored ICU setting using percutaneous placement of titanium Greenfield filters. Duplex scanning after insertion was used to document proper placement, and circumferential engagement of the filter struts in the IVC wall. An abdominal radiograph was also obtained in each case to confirm proper filter location. Duplex ultrasound imaging was repeated within 1 week of insertion to assess IVC and insertion site patency. RESULTS: DGFI was successful in all cases. The filter was deployed at a suprarenal level in one case, as was recognized at the time of postprocedural scanning. Three patients died as a result of their injuries but there were no pulmonary embolism deaths. Repeat duplex scanning was obtained in 17 patients, and revealed no case of IVC or insertion site thrombosis. CONCLUSIONS: Vena caval interruption can be safely performed under ultrasound guidance in a monitored, ICU environment. In selected multiply injured trauma patients, this will reduce the risk, complexity and cost of transport for these critically ill patients. DGFI also reduces procedural costs compared with an operating room or interventional suite, and eliminates intravenous contrast exposure. Preprocedural scanning is essential to identify patients suitable for DGFI, and careful attention must be paid to the known ultrasonographic anatomical landmarks.

OBJECTIVE: To assemble an international panel of experts to develop consensus recommendations on selected important issues on the use of ultrasonography (US) in trauma care. SETTING: R Adams Cowley Shock Trauma Center, University of Maryland Medical System, Baltimore, Md. The conference was held on December 4, 1997. PARTICIPANTS: A committee of two co-directors and eight faculty members, in the disciplines of surgery and emergency medicine, representing four nations. Each faculty member had made significant contributions to the current understanding of US in trauma. RESULTS: Six broad topics felt to be controversial or to have wide variation in practice were discussed using the ad hoc process: (1) US nomenclature and technique; (2) US for organ-specific injury; (3) US scoring systems; (4) the meaning of positive and negative US studies; (5) US credentialing issues; and (6) future applications of US. Consensus recommendations were made when unanimous agreement was reached. Majority viewpoints and minority opinions are presented for unresolved issues. CONCLUSION: The consensus conference process fostered an international sharing of ideas. Continued communication is needed to advance the science and technology of US in trauma care.

PURPOSE: Primary bladder repair with a suprapubic tube is considered to be effective for managing intraperitoneal bladder injury. We compared the outcomes of suprapubic tube placement and no suprapubic tube for this injury. MATERIALS AND METHODS: We reviewed the charts of 31 men and 3 women with a mean age of 28.5 years who required emergency operative repair without a cystogram of traumatic bladder injury from 1992 to 1997. Patient characteristics, mechanism of injury, associated injuries, and short and long-term complications were reviewed. RESULTS: Penetrating and blunt trauma occurred in 28 (82%) and 5 (15%) patients, respectively, while 1 had spontaneous bladder rupture. After primary bladder repair the bladder was drained with a suprapubic tube in 18 cases (53%) and a urethral catheter only in 16 (47%). There were no significant differences between the 2 groups with respect to mechanism of injury, patient age, location of injury in the bladder, coexisting medical illnesses, stability in the field or emergency room, or the bladder repair technique. The 18 patients treated with a suprapubic tube had an associated injury that resulted in 2 deaths, while 13 of the 16 treated with urethral catheter drainage only had an associated injury and 1 died. Urological and nonurological complications in the suprapubic tube versus urethral catheter only group developed in 28 and 33 versus 19 and 19% of the cases, respectively (p <0.05). Followup ranged from 1 month to 4 years. No significant long-term morbidity was noted in either group. CONCLUSIONS: These data indicate that intraperitoneal bladder injuries may be equally well managed by primary bladder repair and urethral catheter drainage only versus suprapubic tube drainage.
