Reanalysis of prehospital intravenous fluid administration in patients with penetrating truncal injury and field hypotension

In 1994, Bickell et al. published a prospective study recommending restricting prehospital intravenous fluids (IVF) to less than 100 cc in patients with penetrating truncal injuries and field hypotension, reporting a 30 per cent mortality with IVF restriction and a 38 per cent mortality with liberal IVF use. However, since this study, few papers have investigated whether emergency medical systems (EMS) adhere to these IVF guidelines. The purpose of this study was to determine whether a policy of IVF restriction is being followed and whether the volume of prehospital and emergency department (ED) IVF affects outcome in patients with penetrating truncal injury and field hypotension at a Level I trauma center in Los Angeles County. A retrospective analysis of a trauma database from 1998 to 2005 of all patients with penetrating truncal injury and field hypotension (systolic blood pressure less than 90 mm Hg) was performed. Multiple variables, including originating EMS agency, mechanism of injury, transport time, Injury Severity Score, field and ED vital signs, and IVF volume infused, complications, and mortality were compared. One hundred ninety-four patients with a median age of 26 years with penetrating truncal injury and field hypotension were analyzed. The most common mechanisms of injury were gunshot (73%) and stab (22%) wounds. The median field systolic blood pressure was 80 mm Hg. The median transport time was 11 minutes. The median prehospital IVF was 500 cc with only 25 per cent receiving less than 100 cc of IVF. There were no differences in the amount of IVF administered by the degree of field hypotension or by originating EMS agency. Median ED IVF was 1000 cc. The overall mortality rate was 25 per cent. When a comparison was made of those receiving less than 100 cc prehospital IVF in comparison to those receiving greater than 100 cc, there were no differences detected with respect to median age, systolic blood pressure, Injury Severity Score, transport time, or morbidity rate. The mortality rate was 21 per cent in the group that received greater than 100 cc of IVF in comparison to a 37 per cent mortality rate in the group that received less than 100 cc IVF (P = 0.04). On multivariate analysis, after adjusting for Trauma Injury Severity Score, there were no differences in survival by the amount of prehospital or ED IVF administered. It appears that the recommendations of IVF restriction for patients with penetrating truncal injuries and field hypotension are not being followed by Los Angeles County EMS. There were no differences in survival with respect to the amount of prehospital or ED IVF. Given the retrospective nature of this study, further investigation is needed to define the role of prehospital IVF resuscitation in these patients.     

Management of adult splenic injury: a 20-year perspective

The objective of this study was to identify changes in the management of blunt splenic injury in adults. Hospital discharge abstract data from Maine were used to identify patients > or = 16 years old discharged between January 1, 1981 and December 31, 2000 with International Classification of Diseases (9th revision) codes indicating splenic injury. Incidence of operative intervention and outcomes for trauma hospitals and other hospitals were determined. The number of splenic injuries was about 75 per year for the first 15 years increasing to 96 per year in the last 5-year period. The rate of operative intervention declined from 71 to 41 per cent and was lower at the trauma hospitals during the last two 5-year periods (41% vs 53%). The rate of operative intervention > 24 hours after admission was 2.2 per cent during the last 10 years of study. The rate of splenorrhaphy remained stable at about 12 per cent throughout the study period. Mortality rates were higher at the trauma hospitals as were the numbers of patients with very severe injuries (Injury Severity Score > 25). There has been a marked decrease in rate of operative intervention for splenic injury in adults especially in the last 10 years. Rates of operative intervention were lower at the trauma hospitals despite higher injury severity. Frequency of delayed intervention was low and did not increase with lower operative rate.     

Splenic Trauma in Scotland: Demographics and Outcomes

Background Splenic trauma is a common organ injury following blunt abdominal trauma. In order to establish the contemporary epidemiology of blunt splenic trauma in Scotland and to detect risk factors associated with patient outcomes, analysis of a multi-center database of trauma patients was performed. Methods The study used data from a prospectively collated multicenter trauma database containing the details of 52,215 trauma patients admitted to participating Scottish hospitals over an 11-year period. Results 672 (1.3%) patients (530 males, 142 females) with splenic trauma were identified; of them, 579 (86.2%) had blunt trauma and 93 (13.8%) had penetrating trauma. The mean age of patients with blunt splenic trauma was 35.7 years (33.8 years for males, 42.0 years for females). Increasing age and female sex was significantly associated with mortality. The most common mechanism for injury was road traffic accidents (71%). In the series, 93.8% of patients had concomitant injuries including head injuries (46.5%), thoracic injuries (37.7%) and liver injuries (30%). A total of 299 (51.6%) patients proceeded to laparotomy, and 256 (44.2%) patients required ICU support. The overall mortality was 33.5%, and the median Injury Severity Score was 48 in patients who died, compared to 22 in those who survived. Increased mortality was associated with concomitant aortic, cardiac, or abdominal injuries. A number of independent risk factors were associated with increased risk of mortality, including concomitant injuries, increased age, and increased Injury Severity Score. Conclusions The incidence of splenic trauma is low, but it accounts for significant mortality. Outcome in the present study was worse in those with advanced age and associated injuries.     

Aortic Trauma in Scotland – A Population Based Study

OBJECTIVES: This population-based study aims to determine the incidence, mechanisms and outcomes of aortic trauma in patients from Scotland between 1992-2002. METHODS: Patients with aortic trauma were identified from the Scottish Trauma Audit Group database. Demographics, mechanism of injury, initial management and outcome were analysed. RESULTS: 165 (0.3%) patients suffered trauma to the thoracic or abdominal aorta. Of these, 130 (79%) patients had an injury of the thoracic aorta, 33 (20%) an injury of the abdominal aorta and two (1%) had injuries of both. There were 123 (75%) men and 42 (25%) women with a median (range) age of 36 (14-90) years. Blunt trauma was responsible for 121 (73%) injuries, of which road traffic accidents were the most common mechanism. A further 44 (27%) aortic injuries were due to penetrating trauma, of which assault was the most common cause. The median (range) Injury Severity Score was 43 (16-75). Ninety (55%) patients died in the emergency department while 59 (32%) underwent attempted operative repair. The operative mortality was 35 (59%) of 59 patients and overall mortality 141 (86%) of 165 patients. CONCLUSIONS: The incidence of aortic trauma presenting to Scottish hospitals is low. The majority of patients do not survive to surgical repair and operative and overall mortality remain prohibitive.     

Blunt thoracic aortic injury

Blunt thoracic aortic injury (BAI) is a rare but often fatal injury that occurs with severe polytrauma. Immediate diagnosis and treatment of BAI are essential for a successful outcome. We reviewed our experience with 20 patients with BAI treated at a Level I trauma center between 1995 and 2006. The mean Injury Severity Score was 38 +/- 14 and 14 patients had an abnormal Glasgow Coma Score; associated injuries included abdomen in 13 patients, extremity in 12, and head in six. Chest x-ray (CXR) findings were suggestive of aortic injury in 15 patients, equivocal in three, and showed no evidence of aortic injury in two. Diagnosis was made by CT angiography (CTA) in 17 patients, transesophageal echocardiography (TEE) in two, and formal angiography in one. Sixteen patients underwent operative repair of BAI. Of these, eight also underwent laparotomy, six had operative repair of extremity fractures, and three had pelvic embolization. Five patients died, three of whom were treated nonoperatively, and length of hospitalization in survivors was 32 +/- 20 days. BAI is rare and often associated with multiple life-threatening injuries complicating diagnosis and treatment. Our data support the aggressive use of CTA even when classic CXR findings are not present. When CT must be delayed for abdominal exploration, intraoperative TEE is useful.     

Recent trends in the management of combined pancreatoduodenal injuries

In an effort to better characterize the natural history of pancreatoduodenal injuries, we present a review of clinical experiences in the treatment of combined traumatic pancreatoduodenal injuries, focusing on patients in extremis. Records of patients with abdominal trauma admitted to a level 1 trauma center from 1997 to 2001 were reviewed. Of 240 patients who sustained a pancreatic or duodenal injury, 33 had combined pancreatoduodenal injuries. Eighty-two per cent of the patients (27/33) in this series had penetrating injuries, 72 per cent (24) sustained gunshot wounds (GSW). Thirty-one patients were male, and the mean age was 33 years (range, 7-74). These patients presented with an average Injury Severity Score (ISS) of 22 +/- 12 and an average Glasgow Coma Score of 14 +/- 2. Overall length of stay was 39 +/- 59 days (range, 0-351 days). These 33 patients underwent a total of 57 laparotomies with an average of 1.7 operations per patient (range, 1 to 5 operations). Eighty-four per cent of the patients had an associated gastrointestinal injury and 45 per cent had a major vascular injury. Thirteen of the 33 (39%) patients presented in extremis, all 13 underwent an abbreviated laparotomy. The complication rate was 36 per cent, including fistula, abscess, pancreatitis, and organ dysfunction. There were 6 hospital deaths for a mortality rate of 18 per cent. Pancreatoduodenal injuries are associated with a variety of other serious injuries, which add to the overall complexity of these patients. Abbreviated laparotomy may be helpful when managing combined pancreatoduodenal injuries in patients who are in extremis.     

Changing patterns of severe craniomaxillofacial trauma in Auckland over eight years

BACKGROUND: This study was performed to review the changing pattern of incidence of severe craniomaxillofacial (CMF) trauma in Auckland over 8 years (1989-1997) and to audit the involvement of the regional plastic surgery service. METHODS: A review of prospectively collected admission data of patients admitted to the Auckland Hospital Department of Critical Care Medicine (DCCM) with severe CMF trauma during 1997. A comparison is made with similar data from 1989. Injury severity was defined using the Injury Severity Score (ISS). RESULTS: Twenty-six patients with severe CMF trauma were admitted to Auckland Hospital DCCM in 1997. Their average ISS was 35. Eighty per cent had a significant head injury. Sixty-two per cent had injuries due to road traffic accidents (RTA) and 42% had positive blood alcohol levels, including 37% of the RTA victims. Twenty-three per cent had their surgical care provided by the regional plastic surgery service. In 1989, 55 patients were admitted to DCCM with severe CMF trauma. The average ISS was 36. Ninety-five per cent had a significant head injury. Seventy-three per cent had injuries due to RTA and 55% had positive blood alcohol, including 60% of the RTA group. CONCLUSIONS: Patients with severe CMF trauma make up a significant proportion of trauma admissions to DCCM and have a high incidence of life-threatening injuries. A multidisciplinary approach is essential. The nature and severity of these injuries has not changed over the last decade. There has been a clear decrease in the incidence of these injuries. This seems to be due to a profound decrease in the rate of RTA associated with alcohol intoxication.     

Emergency laparotomy for abdominal trauma

We have retrospectively reviewed our experience of 153 consecutive patients who underwent emergency laparotomy for suspected intraabdominal injury over a 10-year period.

The commonest cause of injury was road traffic accidents (61 per cent), and the commonest indication for operation was signs of peritoneal irritation (35 per cent). Peritoneal lavage was performed in 62 patients (41 per cent). The liver was the organ most frequently injured (52 patients, 34 per cent) and 52 per cent of these patients died. Splenic injuries occurred in 46 patients (30 per cent). The negative laparotomy rate was 16 per cent. Forty-five patients died (29 per cent) and five of these had negative laparotomies. The Injury Severity Score (ISS) of all patients who died was > 16.     

Patterns of injury and outcomes associated with motocross accidents

Motocross has become a popular recreation activity in Southern California, particularly in the Inland Empire area. In order to evaluate the patterns of injury and outcomes associated with motocross accidents, the Trauma Registry data and charts of all patients with motocross-related injuries from January 2000 to December 2001 were reviewed. Of the 270 patients studied, 265 were males and 5 were females, with a mean age of 26 years (range, 5-61). The mean Injury Severity Score was 6.8 (range, 1-38). Injuries involved extremity trauma in 52 per cent of patients closed head injuries in 33 per cent, blunt chest trauma in 23 per cent, abdominal trauma in 15 per cent, spinal trauma in 14 per cent, and pelvic trauma in 8 per cent. Surgery was required in 96 patients (36%), most commonly for treatment of orthopedic injuries. After initial evaluation, 179 patients were admitted (66%), 60 were discharged home (22%), 29 were transferred for higher level of care (11%), and two expired (1%). The mean hospital length of stay was 2.3 days (range, 1-9). Motocross accidents are most commonly associated with extremity injuries and closed head trauma. Although the overall mortality is low, the morbidity is high, with a large proportion of patients requiring surgery.     

Blunt gastric injuries

Gastric rupture after blunt abdominal trauma is a rare injury with few reports in the literature. The purpose of this study was to review our experience with blunt gastric injuries and compare outcomes with small bowel or colon injuries. All patients with hollow viscus perforations after blunt abdominal trauma from 1992 to 2005 at our level I trauma center were reviewed. Of 35,033 blunt trauma admissions, there were 268 (0.7%) patients with a total of 319 perforating hollow viscus injuries, 25 (0.07%) of which were blunt gastric injuries. When compared with the small bowel or colon injuries, the blunt gastric injury group had a higher Injury Severity Score (22 versus 17, P = 0.04), more patients with a chest Abbreviated Injury Score greater than 2 (36% versus 12%, P < 0.01), and a shorter interval from injury to laparotomy (221 versus 366 minutes, P = 0.017). Multivariate analysis identified five independent risk factors for mortality: age older than 55 years, head Abbreviated Injury Score greater than 2, chest Abbreviated Injury Score greater than 2, the presence of hypotension on admission, and Glasgow Coma Scale 8 or less. The results of this study suggest that mortality in patients with blunt hollow viscus injuries can be attributed to concurrent head and chest injuries, but not the specific hollow viscus organ that is injured.     

Trauma in nonagenarians and centenarians: review of 137 consecutive patients

The purpose of this study was to examine the hospital course and outcomes of elderly trauma patients. We accomplished a retrospective review of all consecutive trauma patients admitted to a level II trauma center from January 2000 to April 2002. Gender, Injury Severity Score (ISS), length of stay (LOS), operative procedure, morbidity, and mortality of patients > or = 90 years of age were compared with younger patients. Of 2645 trauma admissions, 137 patients (5%) were > or = 90 years (range, 90 to 108 years; mean, 93.1 years); 5 patients were > or = 100 years. One hundred eleven (81%) patients were female; 26 (19%) male. Average ISS for patients > or = 90 was 8.75 and was 7.78 for younger patients. One hundred sixteen elderly patients (85%) had ISS < 15. Falls were the most common mechanism of injury (93%), usually ground-level falls (64%). Two hundred ninety-two injuries included 133 fractures and 102 soft tissue injuries. Thirty-four elderly patients (25%) and 733 younger patients (29%) required surgery. Complications developed in 8 per cent of older and 6 per cent of younger patients. Hospital LOS averaged 4.36 days for older and 3.51 days for younger patients. Six older (4.4%) and 63 younger (2.5%) patients died. ISS scores and LOS were slightly higher in elderly patients, but morbidity and mortality were comparable in both groups.     

An appraisal of trauma in the elderly

To review the trends of trauma in the elderly experienced at our trauma center compared with other Level I trauma centers. This was a retrospective trauma registry analysis (1996-2003) of 2783 blunt trauma in elderly (BTE) and 4568 adult (BTA) patients in a Level 1 trauma center. Falls and motor vehicular crashes were the most common mechanisms noted in 47 per cent and 31 per cent (84% and 13% in BTE, 25% and 42% in BTA). BTE were sicker, with higher Injury Severity Scores (ISS), lengths of stay, and mortality (5% vs 2%, P value < 0.05). ISS was 5.2-fold higher in nonsurvivors to survivors in BTA and 2.4-fold in BTE. Elevation in ISS resulted in higher linear increase in mortality in BTE (vs BTA) at any ISS level. Mortality in patients with ISS > or = 25 was 43.5 per cent vs 23.8 per cent. ISS > or = 50 had 31 per cent adult survivors but no elderly survivors. Among isolated injuries, head trauma in the elderly carried the highest mortality, at 12 per cent (19% in patients with an Abbreviated Injury Score > or = 3). Abdominal injuries were the most lethal (18.3% and 41.2% in patients with an Abbreviated Injury Score > or = 3) in multiple trauma victims (41% vs 18% in isolated trauma). There was 4.4-fold increased mortality in the presence of thoracic trauma. Combined head, chest, and abdominal trauma carried the worst prognosis. Thirty-four per cent of BTE and 88 per cent of BTA patients were discharged home. Elderly patients need more aggressive therapy, as they are sicker with higher mortality.     

Intraabdominal injury is common in blunt trauma patients who sustain spinal cord injury

The evaluation of the abdomen in patients with spinal cord injury (SCI) is challenging for obvious reasons. There are very little data on the incidence and complications of patients who sustain SCI with concomitant intraabdominal injury (IAI). To determine the incidence and outcomes of IAI in blunt trauma patients with SCI, a trauma registry and record review was performed between January 1998 and December 2005. Baseline demographic data, Injury Severity Score, and associated IAI were collected. Two groups were established and outcomes were analyzed based on the presence or absence of IAI. Intraabdominal and hollow viscus injures were found in 15 per cent and 6 per cent, respectively, of 292 patients with blunt SCI. The presence of intraabdominal injury varied according to the level of the SCI: 10 per cent of cervical, 23 per cent of thoracic, and 18 per cent of lumbar SCI. The overall mortality was 16 per cent. The presence of intraabdominal injury was associated with longer intensive care unit length of stay (13 versus 6 days, P < 0.01), hospital length of stay (23 versus 18 days, P < 0.05), higher complication rate (46% versus 33%, P = 0.09), and higher mortality (44% versus 11%, P < 0.01) when compared with patients with SCI without IAI. Intraabdominal injuries are common in blunt SCI. Liberal evaluation with computed tomography is necessary to identify injuries early.     

The impact of pre-existing end-stage renal disease on survival in acutely injured trauma patients.

End-stage renal disease and associated dialysis procedures alter homeostatic mechanisms and adversely affect the respiratory, cardiac, and central nervous systems. Currently outcomes research in acutely injured trauma patients utilizes Trauma and Injury Severity Score methodology with the Injury Severity Score and Revised Trauma Score, which do not account for comorbidities. Literature has yet to emerge that analyzes the effects of end-stage renal disease on acutely injured trauma patients. A retrospective review at an urban Level I trauma center was performed of all end-stage renal disease patients' medical records who were admitted for acute traumatic injury from 1994 through 1997. The charts were abstracted for age, sex, race, method of dialysis, specific injury, need for operation, etiology of trauma, length of stay, disposition from hospital, morbidity, and mortality. The Injury Severity Score; probability of survival; and W, M, and Z statistics were then calculated. The data collected were then compared with the overall data for the trauma center including patients with and those without end-stage renal disease during this time period. Mortality for patients with end-stage renal disease after suffering an acute traumatic injury is 2.45 that of the general population. Increased mortality was most prevalent in operative patients and those with Injury Severity Score >15. The average length of stay in the hospital was 55.3 per cent longer for patients with end-stage renal disease. Pre-existing end-stage renal disease negatively impacts survival after traumatic injury. A prospective multicentered study comparing renal patients with nonrenal patients is warranted. This would confirm the need for databases to account for the increased morbidity and mortality associated with end-stage renal disease when calculating probability of survival values for acutely injured trauma patients. Similarly future studies analyzing the affects of other comorbidities such as diabetes, chronic obstructive pulmonary disease, and hypertension on acutely injured trauma patients would help develop a more accurate method of predicting outcomes.     

Prehospital endotracheal intubation for trauma does not improve survival over bag-valve-mask ventilation

BACKGROUND: Few data exist supporting a survival benefit to prehospital endotracheal intubation (ETI) over bag-valve-mask ventilation (BVM) in trauma patients. METHODS: Data were reviewed from all trauma patients transported to our Level I trauma center receiving prehospital ETI or BVM. Mortality was adjusted by age, Revised Trauma Score, Injury Severity Score, and mechanism of injury (penetrating vs. blunt). RESULTS: Of 5,773 patients, 316 (5.5%) had ETI and 217 (3.8%) had BVM. Patients receiving ETI were significantly more like to die (88.9% vs. 30.9%, p < 0.0001). When corrected for Injury Severity Score, Revised Trauma Score, and mechanism of injury, ETI was associated with similar or greater mortality than BVM. ETI patients had longer prehospital times (22.0 vs. 20.1 minutes, p = 0.0241). CONCLUSION: In our trauma system, when corrected for mechanism and severity of anatomic and physiologic injury, ETI confers no survival advantage over BVM and slightly increases prehospital time.     

Popliteal artery trauma in a rural level I trauma center

Popliteal vascular trauma has historically been an urban phenomenon. We hypothesized that rural popliteal artery injury would result more often from blunt mechanisms of injury (MOI), have a longer time to operation, and result in a higher amputation rate. We retrospectively reviewed all cases of popliteal artery injury from December 1994 to May 2001 at our rural trauma center. Age, gender, Injury Severity Score (ISS), MOI, scene transport versus transfer from a referring hospital, time to operation, and operative times were studied. Significance was determined by Student's t test with a P value < or = 0.05. Thirty-two popliteal artery injuries were found. Blunt trauma accounted for 50 per cent of the injuries. Eighty-eight per cent of the patients were transferred from a referring hospital. Patients transported directly from the scene had a higher ISS. Longer operative times translated into an increased need for fasciotomy. The amputation rate was 19 per cent. This is the first attempt to delineate the specific nature of rural popliteal artery trauma. The amputation rate was not different between the two different MOI and was independent of the time to operation. Of those patients receiving an amputation 83 per cent were transferred from another hospital and despite a statistically lower ISS still required an amputation.     

Major trauma with multiple injuries in German children: a retrospective review

BACKGROUND: The aim of this study was to evaluate the demographics, mechanisms, pattern, injury severity, and the outcome (ie, length of intensive care unit [ICU] stay, length of mechanical ventilation, total length of stay, mortality) in multiple-injured children based on a review from the German trauma registry study ("Traumaregister") of the German Society of Trauma Surgery (Deutsche Gesellschaft für Unfallchirurgie e.V.). METHODS: One hundred three German trauma centers took part in the German trauma registry study from January 1997 to December 2003. Five hundred seventeen children (aged 0-15 years) with multiple injuries and an Injury Severity Score of more than 15 in comparison to 11,025 adults were included. Sex, age, and mechanisms and pattern of injury were assessed. The mechanisms of trauma and the anatomical distribution of severe injury (Abbreviated Injury Scale of 3 or more) were analyzed. The Injury Severity Score, the Revised Trauma Score, and the Trauma Score Injury Severity Score were calculated to estimate the severity of injury and mortality. RESULTS: The predominant sex was male. Most cases were caused by traffic-related accidents. Head injuries were most common in children, and severe thoracic injuries increased with age. Mean length of ICU treatment, mechanical ventilation, and total length of stay were shorter in children than in adults. A total of 22.6% of the children aged 0 to 5 years died in the hospital in comparison with in-hospital mortality rate of 13.7% in the 6- to 10-, 20.3% in the 11- to 15-, and 17.0% in the 16- to 55-year-old patients. CONCLUSIONS: There were differences between multiple-injured children and adults concerning injury mechanisms and pattern of injuries. Adults needed a longer mechanical ventilation and a longer ICU therapy. Most deaths could be seen in the youngest patients aged 0 to 5 years.     

How we die: the impact of nonneurologic organ dysfunction after severe traumatic brain injury

Although nonneurologic organ dysfunction (NNOD) has been shown to significantly affect mortality in subarachnoid hemorrhage, the contribution of NNOD to mortality after severe traumatic brain injury (TBI) has yet to be defined. We hypothesized that NNOD has a significant impact on mortality after severe TBI. The trauma registry was queried for all patients admitted between January 2004 and December 2004 who died during their initial hospitalization after severe TBI (head Abbreviated Injury Score 3 or greater). Cause of death and contributing factors to mortality were determined by an attending trauma surgeon from the medical record. The data were analyzed using both Fisher's exact and Wilcoxon rank sum. One hundred thirty-five patients met inclusion criteria. Sixty-seven per cent were males, 83 per cent were white, and the mean age was 38.5 years. Mean length of stay was 2.9 days. Fifty-four patients (40%) had isolated TBI (chest Abbreviated Injury Score = 0, abdominal Abbreviated Injury Score = 0). Of the 81 deaths attributed to a single cause, 48 (60%) patients died from nonsurvivable TBI or brain death, whereas 33 (40%) died of a nonneurologic cause. Cardiovascular and respiratory dysfunction (excluding pneumonia) contributed to mortality in 51.1 per cent and 34.1 per cent of patients, respectively. NNOD contributes to approximately two-thirds of all deaths after severe TBI. These complications occur early and are seen even among those with isolated head injuries. These findings demonstrate the impact of the extracranial manifestations of severe TBI on overall mortality and highlight potential areas for future intervention and research.     

Trauma management in the end-stage renal disease patient

More than 230,000 patients in the United States are being treated for end-stage renal disease (ESRD). This group of patients has not been evaluated for trauma resource use. When these patients are involved in trauma the need for dialysis and awareness of chronic disease processes must be considered in addition to their injuries. There were 4,894 patients admitted to a Level II trauma center over a 4-year period. Fifty-nine of these patients were considered to have ESRD before admission. The charts of these patients were reviewed and compared with those in the general trauma population. The average age of the ESRD patients was 58 years with an average Injury Severity Score of 8 as compared with 31 years of age and Injury Severity Score of 10.9 for the general trauma population. Thirty-four patients required hemodialysis within 48 hours of admission. Ten patients required mechanical ventilation. Eight patients in this study died. The complication and mortality rates among the ESRD patients were 50.8 per cent and 13.5 per cent respectively as compared with 16.3 and 4.7 per cent among the general trauma population. The trauma complication and mortality rates among ESRD patients are approximately three times greater than those in the general trauma population. Because of their coexisting medical problems and the need for dialysis trauma patients with ESRD should be cared for in trauma centers with dialysis capability and access to multidisciplinary services.
