RESUMEN
INTRODUCTION: In highly developed countries, as many as 16 percent of children are physically abused each year. Traumatic brain injury (TBI) is the most common injury in non-accidental trauma (NAT) and is responsible for 80 percent of fatal NAT cases, with most deaths occurring in children younger than three years old. Cases of abusers who refuse withdrawal of life-sustaining medical treatment (LSMT) to avoid criminal charges have previously been reported. Therefore, we hypothesized that NAT is associated with a lower risk for withdrawal LSMT in pediatric TBI. METHODS: The pediatric Trauma Quality Improvement Program database was analyzed (2014 to 2016) for patients aged 16 and younger with TBI and Glasgow Coma Scale (GCS) of 8 and lower on admission. Patients with a head Abbreviated Injury Scale (AIS) of 2 or less or who died within 48 hours were excluded. A multivariable logistic regression model was used for analysis. RESULTS: Of 2,209 TBI patients, 92 (4.2 percent) had withdrawal of LSMT. Compared to those without withdrawal of LMST, those with LMST had statistically similar median age (three years of age versus seven years) and a higher rate of NAT (33.7 percent versus 13.5 percent). The most common specified perpetrator was a father/stepfather/male partner (70 percent). After adjusting for covariates, factors associated with higher risk for withdrawal of LSMT included age of less than three years (OR 2.38, CI 1.34-4.23) and NAT (OR 1.86, CI 1.02-3.41). CONCLUSION: NAT is associated with increased risk for withdrawal of LSMT in pediatric TBI. Age of less than three years is similarly associated with a higher risk for withdrawal of LSMT. Future research in this population is needed to determine what other factors predict withdrawal of LSMT and what resources, such as social workers and/or ethics consults, are utilized.

BACKGROUND: Despite the high incidence of blunt trauma in older adults, there is a lack of evidence-based guidance for computed tomography (CT) imaging in this population. We aimed to identify an algorithm to guide use of a Pan-Scan (Head/C-spine/Torso) or a Selective Scan (Head/C-spine ± Torso). We hypothesized that a patient's initial history and exam could be used to guide imaging. METHODS: We prospectively studied blunt trauma patients aged 65+ at 18 Level I/II trauma centers. Patients presenting >24 h after injury or who died upon arrival were excluded. We collected history and physical elements and final injury diagnoses. Injury diagnoses were categorized into CT body regions of Head/C-spine or Torso (chest, abdomen/pelvis, and T/L spine). Using machine learning and regression modeling as well as a priori clinical algorithms based, we tested various decision rules against our dataset. Our priority was to identify a simple rule which could be applied at the bedside, maximizing sensitivity (Sens) and negative predictive value (NPV) to minimize missed injuries. RESULTS: We enrolled 5,498 patients with 3,082 injuries. Nearly half (47.1%, n = 2,587) had an injury within the defined CT body regions. No rule to guide a Pan-Scan could be identified with suitable Sens/NPV for clinical use. A clinical algorithm to identify patients for Pan-Scan, using a combination of physical exam findings and specific high-risk criteria, was identified and had a Sens of 0.94 and NPV of 0.86 This rule would have identified injuries in all but 90 patients (1.6%) and would theoretically spare 11.9% (655) of blunt trauma patients a torso CT. CONCLUSIONS: Our findings advocate for Head/Cspine CT in all geriatric patients with the addition of torso CT in the setting of positive clinical findings and high-risk criteria. Prospective validation of this rule could lead to streamlined diagnostic care of this growing trauma population. LEVEL OF EVIDENCE: Level 2, Diagnostic Tests or Criteria.
RESUMEN
BACKGROUND: Standardization of trauma centers improves quality of care, yet that comes with financial challenges. The decision to designate a trauma center typically focuses on access, quality of care, and the needs of the local community, but less often considers the financial viability of the trauma center. A level-1 trauma center was relocated in 2017 and this presented an opportunity to compare financial data at two separate locations in the same city. METHODS: A retrospective review was performed on the local trauma registry and billing database in all patients aged ≥19 years on the trauma service before and after the move. RESULTS: 3041 patients were included (pre-move: 1151; post-move: 1890). After the move, patients were older (9.5 years), and more were females (14.9%) and white (16.5%). Increases in blunt injuries (7.6%), falls (14.8%), and motor vehicle accidents (1.7%) were observed after the move. After the move, patients were less likely to be discharged home (6.5%) and more likely to go to a skilled nursing facility (3%) or inpatient rehabilitation (5.5%). Post-move more patients had Medicare (12.6%) or commercial (8.5%) insurance and charges per patient decreased by $2,833, while charges collected per patient increased by $2425. Patients were seen from a broader distribution of zip codes post-move. DISCUSSION: Relocating a trauma center did improve financial viability for this institution. Future studies should consider the impact on the surrounding community and other trauma centers. LEVEL OF EVIDENCE: Level IV.

BACKGROUND: Birthdays provide an opportunity to celebrate; however, they can also be associated with various adverse medical events. This is the first study to examine the association between birthdays and in-hospital trauma team evaluation. METHODS: This retrospective study analyzed trauma registry patients 19-89 years of age, who were evaluated by in-hospital trauma services from 1/1/2011 to 12/31/2021. RESULTS: 14,796 patients were analyzed and an association between trauma evaluation and birthdays was found. The strongest incidence rate ratios (IRRs) were on the day of birth (IRR: 1.78; P < .001) followed by ±3 days of the birthday (IRR: 1.21; P = .003). When incidence was analyzed by age groups, 19-36 years of age had the strongest IRR (2.30; P < .001) on their birthday, followed by the >65 groups (IRR: 1.34; P = .008) within ±3 days. Non-significant associations were seen in the 37-55 (IRR: 1.41; P = .209) and 56-65 groups (IRR: 1.60; P = .172) on their birthday. Patient-level characteristics were only significant for the presence of ethanol at trauma evaluation (risk ratio: 1.83; P = .017). DISCUSSION: Birthdays and trauma evaluations were found to have a group-dependent association, with the greatest incidence for the youngest age group being on their birthday, and the oldest age group within ±3 days. The presence of alcohol was found to be the best patient-level predictor of trauma evaluation.

BACKGROUND: Severe pain and pulmonary complications commonly follow rib fractures, both of which may be improved by surgical stabilization of rib fractures (SSRFs). However, significant postoperative pain still persists which may negatively impact in-hospital outcomes. Combining intercostal nerve cryoablation (INCA) with SSRF may improve those outcomes by further decreasing postoperative pain, opioid consumption, and pulmonary complications. The hypothesis is that INCA plus SSRF reduces opioids consumption compared with SSRF alone. METHODS: The retrospective analysis included trauma patients 18 years or older who underwent SSRF, with or without INCA, in a Level I trauma center between 2015 and 2021. Patients received INCA at the surgeons' discretion based on familiarity with the procedure and absence of contraindications. Patients without INCA were the historical control group. Reported data include demographics, mechanism and severity of injury, number of ribs stabilized, cryoablated nerves, intubation rates and duration of mechanical ventilation. The primary outcome was total morphine milligrams equivalent consumption. Secondary outcomes were intensive care unit length of stay, hospital length of stay, incidence of pneumonia, and tracheostomy rates, and discharge disposition. Long-term outcomes were examined up to 6 months for adverse events. RESULTS: Sixty-eight patients were included, with 44 receiving INCA. There were no differences in rates of pneumonia ( p = 0.106) or duration of mechanical ventilation ( p = 0.687), and hospital length of stay was similar between groups ( p = 0.059). However, the INCA group demonstrated lower total morphine milligrams equivalent ( p = 0.002), shorter intensive care unit length of stay ( p = 0.021), higher likelihood of home discharge ( p = 0.044), and lower rate of intubation ( p = 0.002) and tracheostomy ( p = 0.032). CONCLUSION: Combining INCA with SSRF may further improve in-hospital outcomes for patients with traumatic rib fractures. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

A 19-year-old G1 at 37 weeks presented with acute non-ruptured appendicitis. Her advanced gestational age and surgical anatomy presented a complex surgical scenario. She was treated with intravenous antibiotics and induction of labour, which resulted in resolution of the appendicitis and an uncomplicated vaginal delivery at early term. This case is an example that appendicitis occurring in early-term pregnancy can be successfully managed with intravenous antibiotics, but this is a complex clinical scenario with a limited evidence base to make management decisions. Future studies of medical management of appendicitis in pregnancy, specifically in later gestation, are needed to provide additional information to guide clinicians.

BACKGROUND: Pseudoaneurysms (PAs) caused by traumatic injury to the arterial vasculature have a high risk of rupture, leading to life-threatening hemorrhage and mortality, requiring urgent treatment. The purpose of this study was to determine the technical and clinical outcomes of endovascular treatment of visceral and extremity traumatic pseudoaneurysms. METHODS: Clinical data were retrospectively collected from all patients presenting for endovascular treatment of PAs between September 2012 and September 2018 at a single academic level one trauma center. Technical success was defined as successful treatment of the PA with no residual filling on post-embolization angiogram. Clinical success was defined as technical successful treatment with no rebleeding throughout the follow-up period and no reintervention for the PA. RESULTS: Thirty-five patients (10F/25M), average age (± stdev) 41.7 ± 20.1 years, presented with PAs secondary to blunt (n = 31) or penetrating (n = 4) trauma. Time from trauma to intervention ranged from 2 h - 75 days (median: 4.4 h, IQR: 3.5-17.1 h) with 27 (77%) of PAs identified and treated within 24 h of trauma. Average hospitalization was 13.78 ± 13.4 days. Ten patients underwent surgery prior to intervention. PA number per patient ranged from 1 to 5 (multiple diffuse). PAs were located on the splenic (n = 12, 34.3%), pelvic (n = 11, 31.4%), hepatic (n = 9, 25.7%), upper extremity/axilla (n = 2, 5.7%), and renal arteries (n = 1, 2.9%). Technical success was 85.7%. Clinical success was 71.4%, for technical failure (n = 5), repeat embolization (n = 1) or post-IR surgical intervention (n = 4). There was no PA rebleeding or reintervention for any patient after discharge over the reported follow-up periods. Three patients died during the trauma hospitalization for reasons unrelated to the PAs. CONCLUSIONS: Endovascular treatment of traumatic visceral and extremity PAs is efficacious with minimal complication rates and low reintervention requirements.
RESUMEN
Previous studies have had conflicting results when comparing risk of mortality in patients with gunshot wounds (GSWs) treated at Level-I and II trauma centers. However, the populations studied were restricted geographically. We hypothesized that patients presenting after a GSW to the torso at Level-I centers would have a shorter time to surgical intervention (exploratory laparotomy or thoracotomy) and a lower risk of mortality, compared to Level-IIs in a national database. The Trauma Quality Improvement Program (2010-2016) was queried for patients presenting to Level-I or II trauma center after a GSW to the torso. A multivariable logistic regression analysis was performed. From 17,965 patients with GSWs, 13,812 (76.8%) were treated at Level-Is and 4153 (23.2%) at Level-IIs. There was no difference in the injury severity score (ISS) (p = 0.55). The Level-I cohort had a higher rate of laparotomy (38.9% vs. 36.5%, p < 0.001) with a shorter median time to laparotomy (49 vs. 55 min, p < 0.001) but no difference in rate (p = 0.14) and time to thoracotomy (p = 0.62). After adjusting for covariates, only patients undergoing thoracotomy (OR = 0.66, CI = 0.47-0.95, p = 0.02) or those undergoing non-operative management (NOM) (OR = 0.85, CI = 0.74-0.98, p = 0.03) at a Level-I center had lower risk for death, compared to Level-II. Patients with torso GSWs managed with thoracotomy or NOM at a Level-I center have a lower risk of mortality, compared to a Level-II. Future prospective studies examining variations in practice, resources available and surgeon experience to account for these differences are warranted.

The focused assessment with sonography for trauma (FAST) examination has become the standard of care for rapid evaluation of trauma patients. Extended FAST (eFAST) is the use of ultrasonography for the detection of pneumothorax (PTX). The exact sensitivity and specificity of eFAST detecting traumatic PTX during practical "real-life" application is yet to be investigated. This is a retrospective review of all trauma patients with a diagnosis of PTX, who were treated at a large level 1 urban trauma center from March 2013 through July 2014. Charts were reviewed for results of imaging, which included eFAST, chest X-ray, and CT scan. The requirement of tube thoracostomy and mechanism of injury were also analyzed. A total of 369 patients with a diagnosis of PTX were identified. A total of 69 patients were excluded, as eFAST was either not performed or not documented, leaving 300 patients identified with PTX. A total of 113 patients had clinically significant PTX (37.6%), requiring immediate tube thoracostomy placement. eFAST yielded a positive diagnosis of PTX in 19 patients (16.8%), and all were clinically significant, requiring tube thoracostomy. Chest X-ray detected clinically significant PTX in 105 patients (92.9%). The literature on the utility of eFAST for PTX in trauma is variable. Our data show that although specific for clinically significant traumatic PTX, it has poor sensitivity when performed by clinicians with variable levels of ultrasound training. We conclude that CT is still the gold standard in detecting PTX, and clinicians performing eFAST should have adequate training.

BACKGROUND: Interfacility transfer of undertriaged patients to higher-level trauma centers has been found to result in a delay of appropriate care and an increase in mortality. To address this, for the last 10 years our region has used 911 emergency medical services (EMS) paramedics for rapid re-triage of undertriaged patients to our institution's Level I trauma center. We sought to determine whether using 911 EMS for re-triage to our institution was associated with worse outcomes-with mortality as the primary end point-compared with direct EMS transport from point of injury. STUDY DESIGN: We retrospectively reviewed all trauma activations to our institution during a 16-month period; 3,394 active traumas were analyzed. RESULTS: Two hundred and seventy patients (8%) arrived via 911 EMS re-triage and 3,124 (92%) arrived via direct EMS transport. Total EMS transport time was significantly longer (122.5 minutes vs 33.7 minutes; p < 0.001) between the 2 groups, but there was no significant difference in mortality rates (4.1% vs 3.6%; p = 0.67). CONCLUSIONS: These data show that although using 911 EMS for re-triage is associated with an increase in total transport time, it does not result in an increase in mortality compared with direct EMS transport. We conclude that the use of 911 EMS can be considered a safe method to re-triage patients to higher-level trauma centers.

BACKGROUND: To provide a descriptive analysis of scrotal and testicular trauma in the USA. Additionally, we hypothesized that motorcycle collision would have a higher association with scrotal or testicular trauma and subsequent scrotal or testicular operation, compared to a bicycle collision. METHODS: The National Trauma Data Bank (2007-2015) was queried to identify adult male patients with scrotal or testicular trauma. A multivariable logistic regression analysis was performed. RESULTS: A total of 8,030 patients (0.23%) had scrotal/testicular injury, with 44.6% involved in blunt trauma. A penetrating mechanism occurred in 50.5% of cases, with assault by firearm (75.8%) being the most common. The median age of the patients was 31 years and the median injury severity score was 8. Most had isolated scrotal or testicular trauma (74.5%), with 48.3% requiring scrotal or testicular operation, most commonly repair of laceration (37.3%). Patients involved in a motorcycle collision had higher risk for scrotal/testicular trauma (OR=5.40, CI=4.40-6.61, p=0.0004) and subsequent scrotal/testicular surgery (OR=4.93, CI=3.82-6.36, p=0.0005), compared to bicycle collision. CONCLUSION: Scrotal or testicular trauma is rare but occurs most commonly after assault by firearm. Most patients only have isolated scrotal or testicular trauma, but nearly half require subsequent scrotal or testicular operation. Trauma patients presenting after a motorcycle collision have a higher association of scrotal or testicular trauma and subsequent surgery when compared to those involved in a bicycle collision.
RESUMEN
BACKGROUND: In a systematic review, the level of spinal cord injury (SCI) was not associated with risk for pressure ulcer (PU). We hypothesized that in the acute trauma population, upper-SCI (cervical/thoracic) has greater risk for PU when compared to lower-SCI (lumbar/sacral). We additionally sought to identify risk factors for development of PUs in trauma. METHODS: A retrospective analysis of the NTDB (2007-2015) was performed. Covariates were included in a multivariable logistic regression analysis to determine risk for PU. RESULTS: Of 62,929 patients (0.9%) with SCI, most had an upper-SCI (83%). The overall rate of PUs in patients with SCI was 5.1%. More patients with upper-SCI developed PUs compared to lower-SCI (5.8% vs. 2.2%, p < 0.001). SCI was the strongest predictor for PU (OR = 13.77, CI = 13.25-14.31, p < 0.001). Upper-SCI demonstrated greater risk compared to lower-SCI (OR = 2.81, CI = 2.45-3.22, p < 0.001). CONCLUSIONS: Contrary to previous reports, a higher SCI level is associated with a three-fold greater risk for PU compared to lower SCI.
RESUMEN
BACKGROUND: Femoral vessel injuries are the most common vascular injuries treated in a Level I trauma center. No studies have identified risk factors for survival and complications. STUDY DESIGN: We performed a retrospective, 132-month study that included univariate and multivariate analyses. RESULTS: We studied 204 patients with 298 vessel injuries: 204 were arterial, 94 were venous. Mean age (+/- SD) was 29+/-13 years and mean Injury Severity Score (+/- SD) was 17+/-8. There were 176 (86%) penetrating injuries and 28 (14%) blunt injuries. Arterial repairs included: reverse saphenous vein graft bypass, 108 (53%); primary repair, 53 (26%); PTFE, 21 (10.2%); ligation, 13 (6.4%); and vein patch, 9 (4.4%). Venous repairs included: ligation, 49 (52%); primary repair, 41 (44%); and bypass, 4 (4%). Fasciotomies included: calf, 56 (27%); thigh, 25 (12%); traumatic amputations, 6 (3%); and delayed amputations, 0. Overall survival rate was 91% (186 of 204), and adjusted survival was 95% (excluding emergency department thoracotomy deaths). There were 1 or more complications in 47 (23%), including wound infection, 31 (15%); venous thrombosis, 6 (3%); bleeding, 5 (2.5%); ARDS, 4 (2%); and arterial thrombosis, 1 (0.5%). Predictors of mortality were age>45 years, Injury Severity Score>25, common femoral artery injury, associated venous and abdominal injury, hypotension, hypothermia, and acidosis; coagulopathy in the operating room and the need for PTFE repair also predicted outcomes. Predictors of postoperative complications were intraoperative hypotension, arterial intimal injury, bony fracture, and thoracic injury. CONCLUSIONS: Although survival and limb salvage rates are high for femoral vessel injuries, these injuries incur high complication rates. Independent predictors for mortality are: Injury Severity Score > 25, Glasgow Coma Scale 28, presence of coagulopathy in the operating room, presence of two or more vascular signs, and age > 45 years.

INTRODUCTION: It has been well documented that the use of alcohol correlates with injury risk, especially in DUI (driving under the influence) and DWI (driving while intoxicated). Consumption of alcohol in patients presenting with bicycle-related injuries is associated with greater injury severity, longer hospitalization, and higher health care costs. We hypothesized that intoxicated patients operating a bicycle with traumatic injuries have previous DUI or DWI convictions and had lost their privilege to drive a motor vehicle, resorted to bicycling, and had continued alcohol consumption despite negative previous consequences. METHODS: We retrospectively collected data on injured bicyclists older than 18 years with positive blood alcohol content levels treated from the period January 2009 to June 2014 at a large Level 1 urban trauma center. We then matched each patient by name and date of birth and were able to obtain public criminal records through the Superior Court of California for the local of county. RESULTS: A total of 149 injured bicyclists with positive blood alcohol levels were identified. Their average blood alcohol content was 236.0 mg/dL, and their average age was 41 years. Sixty-six (44.2%) of these patients had prior DUI/DWI convictions with suspension of driving privileges. Ninety-five patients in this group (63.8%) had no health insurance, and 51 patients (34.2%) tested positive for other drugs. Intoxicated bicyclists trended toward longer hospital length compared with nonintoxicated bicyclists (4.60 vs. 3.44 days; p = 0.07). Three (0.02%) of 149 patients were charged with bicycling while intoxicated. CONCLUSION: Intoxicated bicyclists involved in trauma are more likely to have a previous DUI/DWI, have other drug use, tend to have longer hospital stays, and are less likely to have insurance. Bicycle safety education and behavior modification targeting DUI/DWI offenders are warranted. In order to promote injury prevention, resources to increase awareness of this underestimated public health issue should be promoted. LEVEL OF EVIDENCE: Epidemiologic study, level III.

OBJECTIVE: These data describe the critical care procedures performed on, and the resuscitation markers of, critically wounded personnel in Afghanistan following point of injury (POI) transports and intratheater transports. Providing this information may help inform discussion on the design of critical care transportation platforms for future conflicts. METHODS: The Department of Defense Trauma Registry (DoDTR) was queried for descriptive data on combat casualties with Injury Severity Score (ISS) greater than 15 who were transported in Operation Enduring Freedom (OEF) from 1 January 2010 to 31 December 2010. Both POI transportation events and interfacility transportation events were reviewed. Base deficit (BD) was evaluated as a maker of resuscitation, and international normalized ratio (INR) was evaluated as a measure of coagulopathy. RESULTS: There were 1198 transportation events that occurred during the study period--634 (53%) transports from the POI and 564 (47%) intratheater transports. Critical care interventions were performed during 147 (12.3%) transportation events, including intubation, cricothyrotomy, double-lumen endotracheal tube placement, needle or tube thoracostomy, central venous access placement, and cardiopulmonary resuscitation. The mean BD on arrival in the emergency department was -5.4 mEq/L for POI transports and 0.68 mEq/L intratheater transports (ρ<.001). The mean INR on arrival in the emergency department was 1.48 for POI transports and 1.21 for intratheater transports (ρ<.001). CONCLUSIONS: Critical care interventions were needed frequently during evacuation of severely injured personnel. Furthermore, many troops arrived acidotic and coagulopathic following initial transport from POI. Together, these data suggest that a platform capable of damage control resuscitation and critical care interventions may be warranted on longer transports of more critically injured patients.

BACKGROUND: Historically, the incidence of genital and urinary tract (GU) injuries in major conflicts has been approximately 5%. To mitigate the risk of blast injury to the external genitalia, the United States and United Kingdom issued protective overgarments and undergarments to troops deployed in support of Operation Enduring Freedom. These two systems combined constitute the pelvic protection system (PPS). Our hypothesis was that PPS use is associated with a reduction of GU injuries in subjects exposed to dismounted improvised explosive device blast injuries. METHODS: We identified two groups for comparison: those who were confirmed to have worn the PPS at time of injury (n = 58) and a historical control group who were confirmed as not wearing the PPS (non-PPS) (n = 61). Patients with any level of lower extremity amputation from dismounted improvised explosive device blast mechanism were included. The primary outcome measure was presence of a GU injury on admission. A univariate analysis assessing the strength of association with odds ratios and 95% confidence intervals was performed between the PPS and non-PPS groups. RESULTS: Mean Injury Severity Score (ISS) was higher in the PPS versus the non-PPS group (26.1 vs. 19.3, p = 0.0012). Overall, 31% of the patients in the PPS group sustained at least one GU injury versus 62.3% in the non-PPS group. The odds ratio of sustaining a GU injury in the PPS group as compared with the PPS group is 0.28 (31% vs. 62.3%; 95 % confidence interval, 0.62-0.12; p < 0.001). The most frequent injures were open scrotal/testes wounds, followed by open penis, and open bladder/urethra injuries. CONCLUSION: The use of the PPS is associated with a decreased odds ratio of GU injury. Despite a 31% absolute reduction, future work should focus on improved efficiency.

HYPOTHESIS: Awareness of guidelines for damage control can improve patient outcomes after postraumatic open abdomen. DESIGN: Retrospective (November 1992 to December 1998), prospective (January 1999 to July 2001), 104-month study. SETTING: Los Angeles County and University of Southern California Medical Center, Los Angeles. PATIENTS: All patients undergoing damage control resulting in posttraumatic open abdomen. MAIN OUTCOME MEASURES: The main outcome measure was survival. Data were also collected on surgical findings and indications for damage control, including organs injured, intraoperative estimated blood loss, and intraoperative fluids, blood, and blood products administered. Postoperative complications, length of time patients had an open abdomen, and surgical intensive care unit and hospital length of stay were also recorded. RESULTS: No difference in mortality existed between patients admitted before awareness of guidelines (group 1; 21 [24%] of 86 patients died) and patients who underwent damage control following these suggested guidelines (group 2; 13 [24%] of 53 patients died) (P =.85). Of the 139 patients, 100 had penetrating injuries and 39 had blunt injuries. Estimated blood loss was 4764 +/- 5349 mL. Mean intraoperative fluid replacement was 22 034 mL. One hundred one patients (73%) experienced 228 complications, for a mean of 2.26 complications per patient. Group 1 patients spent a longer time in the operating room (mean, 4.09 +/- 1.99 hours; range, 0.4-9.5 hours) vs group 2 patients (mean, 2.34 +/- 1.50 hours; range, 0.3-6.2 hours; P<.001). The surgical intensive care unit length of stay was 23.5 +/- 18.3 days vs 8.7 +/- 14.9 days (P<.001), and the hospital length of stay was 37.4 +/- 27.5 days vs 12.4 +/- 21.0 days (P<.001) in survivors and nonsurvivors, respectively. CONCLUSIONS: We recommend close monitoring of intraoperative outcome predictors as validated within our guidelines and recommend following our model for early institution of damage control.

HYPOTHESIS: To identify significant risk factors associated with mortality in patients with a Glasgow Coma Scale score of 3. DESIGN: Trauma registry study. SETTING: Level I urban trauma center. PATIENTS: A total of 760 patients with head injury with an admission Glasgow Coma Scale score of 3. Analysis was performed in all patients and in only patients who reached the hospital alive and had no major extracranial injuries (exclusion of patients with a chest or abdominal Abbreviated Injury Score [AIS] >3). MAIN OUTCOME MEASURES: Stepwise logistic regression analysis was used to identify independent risk factors associated with mortality. RESULTS: Blunt trauma accounted for 477 (63%) and penetrating trauma for 283 (37%) of the 760 head injuries. Penetrating trauma was significantly more likely to be associated with a lack of vital signs on admission (15% vs 9%; P = .03). Overall mortality was 76% (94% for penetrating injuries and 65% for blunt injuries; P<.001). Overall, 79% of patients had a head AIS of 4 or greater. Mortality in the subgroup was 64% (320/497) and was significantly higher in penetrating vs blunt trauma (89% vs 52%; P<.001). Penetrating trauma, high head AIS, hypotension on admission, and age older than 55 years were independent significant risk factors associated with mortality. Only 10% of the 177 survivors had good functional outcome at hospital discharge. Eighty-six patients (17% of those with vital signs on admission) became organ donors. CONCLUSIONS: Patients with head injury with an admission Glasgow Coma Scale score of 3 have a poor prognosis. Mechanism of injury, head AIS, hypotension on admission, and age play a critical role in outcome. These patients are an important source of organ donation and should be evaluated and resuscitated aggressively.

HYPOTHESIS: Iliac vascular injuries incur high mortality. DESIGN: Retrospective 100-month study (January 1, 1992, through April 30, 2000). PATIENTS: One hundred forty-eight patients with 185 iliac vessel injuries. OUTCOME MEASURES: Survival and mortality, analyzed by univariate and logistic regression. RESULTS: Admission mean +/- SD systolic blood pressure was 81 +/- 42 mm Hg, mean Revised Trauma Score was 6.0 +/- 2.8, and mean Injury Severity Score was 20.0 +/- 9.5. The mechanism of injury was penetrating in 140 patients (95%) and blunt in 8 (5%). The mean estimated blood loss was 6246 +/- 6174 mL. Of the 185 injured vessels, 71 (99%) of 72 iliac arteries were repaired, 101 (89%) of 113 iliac veins were ligated, and 12 (11%) of 113 iliac veins were repaired. Overall survival was 51% (76/148). Mortality was 82% (49/72) in patients with exsanguination. Survival by vessel: iliac artery, 57% (20/35); iliac vein, 55% (42/76); and iliac artery and vein, 38% (14/37). Significant predictors of outcome were thoracotomy in the emergency department, associated aortic injury, inferior vena cava injuries, iliac artery and vein injury, intraoperative arrhythmia, and intraoperative coagulopathy. On logistic regression, independent risk factors for survival were absence of thoracotomy in the emergency department, surgical management, and arrhythmia. Mortality by grade on the Organ Injury Scale of the American Association for the Surgery of Trauma (AAST-OIS) was as follows: grade III, 35% (33/95); grade IV, 71% (24/34); and grade V, 79% (15/19). CONCLUSIONS: Mortality remains high. Associated vessel injuries and intraoperative complications predict mortality. AAST-OIS grade for abdominal vascular injuries correlates well with mortality.
