RESUMO

OBJECTIVES: To identify predictive factors causing mortality in patients with injuries to the portal (PV) and superior mesenteric veins (SMV). DESIGN: Retrospective analysis of prospectively collected data. MATERIALS AND METHODS: Adults admitted with blunt or penetrating PV and SMV injuries at an academic level I trauma center during a 20-year period. RESULTS: Of 26,387 major trauma victims admitted from 1987 through 2006, 26 sustained PV or SMV injuries (PV=15, SMV=11). Mechanism of injury was penetrating in 19 (73%) and 20 were in shock. Active hemorrhage occurred in 21. Most patients had associated injuries (2.9+/-1.8/patient). Mean Injury Severity Score (ISS) was 27.8+/-16.8. All PV injuries underwent suture repair and 27% of SMV injuries were ligated. Overall mortality was 46% (PV=47%, SMV=45%). Stab wounds had a lower mortality (31%) compared to gunshot wounds (67%) and blunt injuries (57%). Nonsurvivors had a higher ISS (35.8 vs. 20.9; p=0.02), more associated injuries (3.7 vs. 2.2; p=0.02), were older, and had active hemorrhage. Active hemorrhage (p=0.04) was independently related to death while shock on admission (odds ratio=6.1, p=0.61) trended toward higher mortality. CONCLUSION: Despite improvements in trauma care, mortality of PV and SMV injuries remains high. Shock, active hemorrhage, and associated injuries were predictive of increased mortality.

RESUMO

BACKGROUND: Safer cars, decreased violence, and nonoperative management have changed the trauma patient's nature. We evaluated changes in a Level I trauma center over 15 years and considered their effect on trauma surgeons. METHODS: From January 1985 through August 1999, 16,799 trauma registry patients were analyzed for mechanism of injury, Injury Severity Score, and procedures. RESULTS: Mean Injury Severity Score decreased from 15.9 to 10.7 and length of stay fell from 8.0 days to 5.9 days. There were significant decreases in penetrating trauma admissions and percentage of patients with Abbreviated Injury Scale score > 3 for head, chest, and abdomen. Frequency of craniotomy, thoracotomy, and laparotomy dropped dramatically. CONCLUSION: Significant decreases in injury severity, penetrating violence, and operations have occurred over 15 years. These changes will have profound effects on the practice of trauma surgeons and on surgical education.

RESUMO

INTRODUCTION: We present our experience in the management of penetrating pancreatic injuries, focusing on factors related to complications and death. METHODS: Retrospective trauma registry-based analysis of 62 consecutive patients with penetrating pancreatic injuries during an 11-year period. Overall injury severity was assessed by the injury severity score (ISS) and the penetrating abdominal trauma index (PATI). Pancreatic injuries were graded according to the American Association for the Surgery of Trauma (AAST) Organ Injury Scaling (OIS). Complications were characterised using standardised definitions. Mortality was recorded as early (within 48 h after admission) and late (after 48 h). RESULTS: Thirty patients suffered gunshot wounds and 24 had grade I pancreatic injuries. Shotgun and gunshot wounds were more destructive than stab wounds (higher PATI, number of intraabdominal injuries and mortality). Seventeen patients died. Most deaths occurred within 1 h after admission due to massive bleeding and severe associated injuries. Only one death was potentially related to the pancreatic injury. Mortality rate also correlated with pancreatic injury grading. Sixty-one patients had associated intraabdominal injuries. Combined pancreaticoduodenal injuries were present in 13 patients, and five died. Simple drainage was the most common procedure performed. Pancreas-related complications were found in 12 out of 47 patients who survived more than 48 h; intraabdominal abscess (n=7) that was associated with colon injuries, and pancreatic fistula (n=5). CONCLUSION: An approach based on injury grade and location is advised. Routine drainage is recommended; distal resection is indicated in the presence of main duct injury, and the management of severe injuries will be tailored according to the overall physiologic status, presence of associated injuries, and duodenal viability. Morbidity and mortality is mainly due to associated injuries.

RESUMO

OBJECTIVE: Pregnancy imposes significant physiologic demands that may confuse and complicate the evaluation, resuscitation, and definitive management of pregnant women who sustain trauma. Accurate prediction of fetal outcome after trauma remains elusive. The objective of this study was to characterize patterns of injury in pregnant women, to determine if pregnancy affects maternal morbidity and mortality after trauma, and to identify predictors of fetal death. METHODS: We performed a retrospective, case-control analysis of all injured pregnant patients admitted to the Trauma Service at the University of California San Diego Medical Center from 1985 to 1995. RESULTS: We identified 114 injured pregnant patients. Motor vehicle crashes accounted for 70% of injuries, and of these, 46% of patients were not using seat belts or helmets. Violence accounted for 12% of injuries. Injured pregnant women with Injury Severity Scores > 8 demonstrated similar mortality, morbidity, and length of stay to matched nonpregnant control patients. Pregnant women were more likely to sustain serious abdominal injury and were less likely to sustain severe head injury. Identified risk factors for fetal loss include maternal death, overall maternal injury severity, the presence of severe abdominal injury, and the presence of hemorrhagic shock. CONCLUSION: There appears to be a group of pregnant women in San Diego at high risk for traumatic injury who should be targeted for preventative strategies including improved seat belt use. Pregnancy does not increase mortality or morbidity after trauma but influences the pattern of injury. Maternal death, high Injury Severity Score, serious abdominal injury, and hemorrhagic shock are risk factors for fetal loss.

RESUMO

BACKGROUND: The purpose of this study was to identify the causes and time to death of all trauma victims who died at a level I trauma center during an 11-year period. STUDY DESIGN: Autopsies were performed on all patients who died secondary to trauma. Retrospective review of these autopsies was carried out and appended to existing trauma registry data. Standard definitions were used to attribute the cause of death in each case. Preventable deaths were determined by a standardized peer review process. RESULTS: Between January 1985 and December 1995, a total of 900 trauma patients died. This represented 7.3% of all major trauma admissions (12,320). Seventy percent of these patients died within the first 24 hours of admission. Thoracic vascular and central nervous system (CNS) injuries were the most common causes of death in the first hour after admission to the hospital. CNS injuries were the most common causes of death within the 72 deaths after admission. Acute inflammatory processes (multiple organ failure, acute respiratory distress syndrome, and pneumonia) and pulmonary emboli were the leading causes of death after the first 72 hours. Overall, 43.6% (393 of 900) of all trauma deaths were caused by CNS injuries, making this the most common cause of death in our study. The preventable death rate was 1%. CONCLUSIONS: The first 24 hours after trauma are the deadliest for these patients. Primary and secondary CNS injuries are the leading causes of death. Prevention, early identification, and treatment of potentially lethal injuries should remain the focus of those who treat trauma patients.

RESUMO

BACKGROUND: Direct admission to the operating room (OR) can shorten the time to incision. A protocol for operating room resuscitation was established with patient triage based on (1) cardiac arrest, (2) hypotension unresponsive to field fluid resuscitation, or (3) uncontrolled external hemorrhage. METHODS: Operating room resuscitation over 11 years was reviewed to determine whether the triage criteria correctly identified patients requiring operation. Survival was analyzed and compared with the probability of survival (Ps) determined at the scene. RESULTS: Operating room resuscitation patients were more likely to require a major operation regardless of mechanism of injury. Of 476 patients with penetrating injury, 170 patients had persistent low blood pressure (<90 mm Hg), and 146 (85.9%) of these required major operative intervention. The mean time to incision in this group was 21.7-67.5 minutes less than for patients not receiving OR resuscitation. Observed survival was significantly greater than that predicted for this group. CONCLUSIONS: Field triage criteria are able to reliably identify patients who require immediate major operative intervention. Direct admission to the OR results in a more timely initiation of operative therapy for patients requiring emergency surgical procedures.

RESUMO

BACKGROUND: Retroperitoneal vascular injury remains one of the most frequent causes of death following abdominal trauma. A risk analysis of the association between potential outcome predictors and mortality following abdominal aorta and inferior vena cava injuries was performed. METHODS: Eighty-nine patients sustaining abdominal aortic or inferior vena cava injury were concurrently evaluated for a 10-year period and retrospectively reviewed. A multiple logistic regression model evaluated the following variables:presence of shock on admission, base deficit (< -10 or > or = -10), classification by the organ injury scale (OIS), blood transfusion, crystalloid infusion, total infusion volume, associated injuries, site of injury, and presence of retroperitoneal tamponade. RESULTS: Overall mortality for all injuries was 57%. Excluding all death on arrival (DOA) patients, the mortality rate decreased to 45.7%. Death following abdominal aortic injuries was significantly associated with free bleeding in the peritoneal cavity, acidosis, and an injury in the suprarenal location (OIS > 4). For inferior vena cava injuries and combined abdominal aortic and inferior vena cava injuries, death was associated with free bleeding, the suprarenal location (OIS = 4), and the presence of shock on admission as well. CONCLUSIONS: Despite advances in transport and resuscitation, mortality of aortic and vena cava injuries remains unchanged. Shock on admission, bleeding without retroperitoneal tamponade, acidosis, and the suprarenal location each play a significant role in mortality. Immediate identification associated with a rapid surgical approach are the only factors that may improve survival of such devastating injuries.

RESUMO

The use of prehospital tube thoracostomy (TT) for the treatment of suspected tension pneumothorax (TPtx) in trauma patients is controversial. A study is presented that reviews a 6-year experience with the use of needle catheter aspiration (NA) and chest tubes performed in the field by air medical personnel. Prehospital flight charts and hospital records from 207 trauma patients who underwent one or both of these procedures in the field were retrospectively reviewed. The clinical indications used to determine treatment are presented for both procedures. Improvement in clinical status of patients observed by flight personnel were similar for both treatment groups (54% for NA, 61% for TT). Thirty-two (38%) of the TT patients had failed NA attempts prior to chest tube placement. Average time on scene (T.O.S.) was significantly greater for the TT group (25.7 min versus 20.3 min for NA group). Fewer patients were pronounced dead on arrival (D.O.A.) with TT treatment compared to NA alone (7% versus 19%, respectively). Injury severity scores, number of hospital complications, length of stay (L.O.S.), and total hospital costs were not different between the two groups. There were no cases of lung damage or empyema formation associated with prehospital TT treatment. Overall mortality was similar for both groups. From these data, we conclude that NA is a relatively rapid intervention in the treatment of suspected TPtx in the prehospital setting; however, TT is an effective adjunct for definitive care without increasing morbidity or mortality. A better understanding of the physiology of intrapleural air masses is needed to determine the most effective decompression requirements prior to aeromedical transport.

RESUMO

Complications in trauma care occur because of provider-related or patient disease-related events. Strictly defined standardized definitions of both types of complications are needed to develop strategies for problem resolution. The frequency and characteristics of 135 disease-related and provider-related complications were examined for a 3-year period in a level I university trauma service in all patients meeting Major Trauma Outcome Study (MTOS) criteria. Provider-related complications were analyzed for recurrent process errors to be targeted for corrective action. Complication events occurred in 2764 of 3327 patients, with provider-related complications in 759. Twenty-three percent (175) of complications were judged unjustified and 16 patterns of recurrent process-of-care errors were identified. Delay in trauma team activation was caused by insensitivity of field triage protocols and inadequate recognition of injury patterns. Delays in diagnosis or surgery were caused by inadequate performance of standard work-up, inadequate recognition of injury severity by providers, diagnostic procedure interpretation errors, and errors in prioritizing the order of diagnostic procedures. Errors in technique were attributed to inexperience, haste, unfamiliarity with devices, lack of developed institutional techniques, and failure of providers to use recognized endpoints. Errors in judgment were attributed to failure to access available patient information, proceeding despite available information, and failure to utilize available care guidelines. Further reduction in provider-related morbidity in an organized trauma system requires this type of analysis, which identifies the need to change the process of care through education or adjustment of protocols for standardization care delivery in addition to the traditional focus on outcomes.

RESUMO

The purpose of this study is an analysis of 630 field intubations of trauma patients by flight personnel of the San Diego Life Flight program. We compared nasotracheal intubation to rapid sequence induction orotracheal intubation and noninduced orotracheal intubation. We measured success of intubation route, complications, and overall patient outcome. Flight records, quality assurance flight procedure data, and hospitalization data from the San Diego Trauma Registry were reviewed over a 4-year period, from 1988 to 1991. The results of our study show that rapid sequence induction orotracheal intubation has a higher success rate, fewer complications, and a better patient outcome compared to noninduced orotracheal intubation and blind nasotracheal intubation. We recommend that rapid sequence induction oral intubation be the standard method for prehospital airway management in trauma patients.

RESUMO

Varying institutional definitions and degrees of surveillance limit awareness of the true incidence of posttraumatic pulmonary complications. Prospective review with standardized definitions of 25 categories of pulmonary complications was applied to a university level I trauma service over 3 years to establish the true incidence. Potential injury-related predictors of individual complications were determined using multiple logistic regression analysis and adjusted odds ratios were calculated, thereby controlling for the effect of other covariants. Significance was attributed to p < 0.05. Of 3289 patients meeting MTOS criteria, pulmonary complications occurred in 368 (11.2%). Pulmonary complications account for one third of all disease complications. Significant associations with pneumonia included age, the presence of shock on admission, significant head injury, and surgery to the head and chest. Significant risk for atelectasis occurred in patients with blunt injury mechanism, ISS > 16, shock on admission, and severe head injury. Risks for development of respiratory failure included age > 55 years, the mechanism of "pedestrian struck", and the presence of significant head injury. Risk factors for ARDS included surgery to the head and a Trauma Score < 13 on arrival. Significant predictors for pulmonary embolism included ISS > 16, shock on admission, and extremity and pelvis injuries. The true incidence of pulmonary complications is established with this kind of analysis and focuses attention on (1) groups at high risk for developing complications, (2) groups for which current therapeutic modalities are still ineffective, and (3) defining the need to refocus on prospective research rather than ineffective processes of care.

RESUMO

The benefit derived from in-house board-certified attending surgeons (IHBCS) staffing trauma centers has recently been questioned. We compared the outcomes and provider-related complications of patients with severe injuries who were treated at two university trauma centers, one with IHBCS, and one with PGY-4 or PGY-5 residents in house (RIH). The RIH center had a significantly longer resuscitation time (160 vs. 58.8 minutes; p < 0.01). Except in cases of vascular injury, the odds ratio of dying at the RIH institution was significantly greater in all groups when the variables of transport time, Revised Trauma Score, and ISS were controlled. Errors in judgment were significantly more likely to have been made at the RIH institution in all groups. It is concluded that the management and ultimate outcome are significantly improved when IHBCS are involved with the resuscitation and early care of specific cohorts of severely injured patients.

RESUMO

As the number of preventable trauma-related deaths plateaus as a result of trauma system development, new directions for quality improvement in trauma care must come from analyzing morbidity with standardized methods to establish thresholds for provider-related and disease-specific complications. To establish such thresholds and determine priorities for improvements in quality all trauma patients who died, who were admitted to the ICU or OR, who were hospitalized for more than 3 days, or who were interfacility transfers to an academic trauma service, were concurrently evaluated for 1 year. All complication events were defined, reviewed, tabulated, and classified using 135 categories of complications. These categories were subdivided into provider-specific and disease-specific complications. Provider-related complications were classified as justified or unjustified to allow identification of events with a potential for improvement. A total of 1108 patients were admitted (mean ISS, 17); there were 97 deaths. Three potentially preventable deaths were identified, 857 complication events were identified, and 285 provider-related complications were responsible for errors with potential for improvement in 59 events (21%). Disease-specific morbidity was primarily related to infection; pneumonia accounted for 36% of all infectious complications and systemic infection for only 8.6% of infectious complications. Organ failure and other major systemic complications occurred in 2%-8% of patients. This type of analysis forms the basis on which to determine thresholds of provider-specific and disease-specific morbidity in a trauma hospital and serves as a guide to direct efforts toward continuous quality improvement.

RESUMO

STUDY OBJECTIVE: To develop a new trauma decision rule. DESIGN: Retrospective clinical review. SETTING: Level I trauma center. TYPE OF PARTICIPANTS: 1,004 injured adults. MEASUREMENTS AND MAIN RESULTS: A new trauma decision rule was derived from 1,004 injured adult patients using a new operational definition of major trauma. The rule, termed the Trauma Triage Rule, defines a major trauma victim as any injured adult patient whose systolic blood pressure is less than 85 mm Hg; whose motor component of the Glasgow Coma Score is less than 5; or who has sustained penetrating trauma of the head, neck, or trunk. Using the operational definition of major trauma, the rule had a sensitivity of 92% and a specificity of 92% when tested on the 1,004-patient cohort. CONCLUSION: The Trauma Triage Rule may significantly reduce overtriage while only minimally increasing undertriage. This approach must be validated prospectively before it can be used in the prehospital setting.

RESUMO

To better define the serum osmolar and compositional changes associated with the infusion of a large volume of hypertonic saline solution (sodium of 250 milliequivalents per liter), we compared resuscitation using a hypertonic crystalloid (HSL) to Ringer's lactate (RL) in 52 patients undergoing aortic reconstruction. There were no differences between the groups in any of the preoperative measurements, the duration of operation, operative blood loss or transfusion requirement. The RL group required 9.5 liters of fluid intraoperatively as compared with 6.3 liters required by the HSL group (p less than 0.01). There was no significant difference between the groups in the amount of sodium infused to achieve resuscitation or in the sodium balance at the end of the study period. Hypernatremia (average maximum serum sodium: 157 milliequivalents per liter) and hyperosmolarity (average maximum serum osmolarity: 320 milliosmoles per liter) resolved in the HSL group within 48 hours. Correction of the hyperosmolar state was thought to be due to the judicious administration of free water and a decrease in renal free water clearance. The HSL group required significantly greater potassium administration during the early postoperative period due to increased kaluresis. HSL is safe and effective for use in the resuscitation of moderate blood volume deficit. Changes in serum sodium values and in osmolarity resolve rapidly. The serum potassium level should be monitored closely and replaced aggressively.
