- Abstract
Importance: The role of acute care surgeons is evolving; however, no guidelines exist for the selective treatment of patients with traumatic brain injury (TBI) exclusively by acute care surgeons. We implemented the Brain Injury Guidelines (BIG) for managing TBI at our institution on March 1, 2012., Objective: To compare the outcomes in patients with TBI before and after implementation of the BIG protocol., Design, Setting, and Participants: We conducted a 2-year analysis of our prospectively maintained database of all patients with TBI (findings of skull fracture and/or intracranial hemorrhage on an initial computed tomographic scan of the head) who presented to our level I trauma center. The pre-BIG group included patients with TBI from March 1, 2011, through February 29, 2012, and the post-BIG group included patients from July 1, 2012, through June 30, 2013., Main Outcomes and Measures: The primary outcome measures were patients with repeated computed tomography of the head and neurosurgical consultations. Secondary outcome measures were findings of progression of intracranial hemorrhage on repeated computed tomographic scans, neurosurgical intervention, hospital admission, intensive care unit admission, hospital and intensive care unit length of stay, 30-day readmission rate, and hospital costs per patient., Results: A total of 796 patients (415 in the pre-BIG group and 381 in the post-BIG group) were included. There was a significant reduction (19.0%) in the rate of neurosurgical consultation (post-BIG group, 273 patients [71.7%]; pre-BIG group, 376 [90.6%]; P < .001), repeated computed tomography of the head (post-BIG group, 255 patients [66.9%]; pre-BIG group, 381 patients [91.8%]; P < .001), hospital (post-BIG group, 330 [86.6%]; pre-BIG group, 398 [95.9%]; P < .001) and intensive care unit admission (post-BIG group, 202 [53.0%]; pre-BIG group, 257 [61.9%]; P = .01), hospital length of stay (post-BIG group, 5.4 [4.5] days; pre-BIG group, 6.1 [4.8] days; P = .03), and hospital costs per patient ($4772 per patient; P = .03) with implementation of BIG. There was no difference in the in-hospital mortality rate (post-BIG group, 62 patients [16.3%]; pre-BIG group, 69 patients [16.6%]; P = .89), progression of intracranial hemorrhage on repeated scans (post-BIG group, 41 patients [10.8%]; pre-BIG group, 59 patients [14.2%]; P = .14), neurosurgical intervention (post-BIG group, 61 patients [16.0%]; pre-BIG group, 59 patients [14.2%]; P = .48), and 30-day readmission rate (post-BIG group, 31 patients [8.1%]; pre-BIG group, 37 patients [8.9%]; P = .69) after implementation of BIG., Conclusions and Relevance: Implementation of BIG is safe and cost-effective. BIG defines the management of TBI without the need for neurosurgical consultation and unnecessary imaging. Establishing a national, multi-institutional study implementing the BIG protocol is warranted.

- Abstract
Background: The use of prothrombin complex concentrate (PCC) to reverse acquired (coagulopathy of trauma) and induced coagulopathy (preinjury warfarin use) is well defined., Objective: To compare outcomes in patients with traumatic brain injury without warfarin therapy receiving PCC as an adjunct to fresh frozen plasma (FFP) therapy compared with patients receiving FFP therapy alone., Methods: All patients with traumatic brain injury coagulopathy without warfarin therapy who received PCC (25 IU/kg) in conjunction with FFP or FFP alone at our Level I trauma center were reviewed. Coagulopathy was defined as an international normalized ratio >1.5. The groups (PCC + FFP vs FFP alone) were matched using propensity score matching on a 1:2 ratio for age, sex, Glasgow Coma Scale score, Injury Severity Score, head Abbreviated Injury Scale score, and international normalized ratio (INR) on presentation. The primary outcome measure was time to craniotomy. Secondary outcome measures were blood product requirements, cost of therapy, and mortality., Results: A total of 1641 patients were reviewed, 222 of whom were included (PCC + FFP, 74; FFP, 148). The mean ± standard deviation age was 46.4 ± 21.7 years, the median (range) Glasgow Coma Scale score was 8 (3-12), and the mean ± standard deviation INR on presentation was 1.92 ± 0.6. PCC + FFP therapy was associated with an accelerated correction of INR (P = .001) and decrease in overall pack red blood cell (P = .035) and FFP (P = .041) administration requirement. Craniotomy was performed in 26.1% of patients (n = 58). Patients who received PCC + FFP therapy had faster time to craniotomy (P = .028) compared with patients who received FFP therapy alone., Conclusion: PCC as an adjunct to FFP decreases the time to craniotomy with faster correction of INR and concomitant decrease in the need for blood product requirement in patients with traumatic brain injury exclusive of prehospital warfarin therapy.

- Abstract
Introduction: Conventionally, a Glasgow Coma Scale (GCS) score of 13-15 defines mild traumatic brain injury (mTBI). The aim of this study was to identify the factors that predict progression on repeat head computed tomography (RHCT) and neurosurgical intervention (NSI) in patients categorized as mild TBI with intracranial injury (intracranial haemorrhage and/or skull fracture)., Methods: This study performed a retrospective chart review of all patients with traumatic brain injury who presented to a level 1 trauma centre. Patients with blunt TBI, an intracranial injury and admission GCS of 13-15 without anti-platelet and anti-coagulation therapy were included. The outcome measures were: progression on RHCT and need for neurosurgical intervention (craniotomy and/or craniectomy)., Results: A total of 1800 patients were reviewed, of which 876 patients were included. One hundred and fifteen (13.1%) patients had progression on RHCT scan. Progression on RHCT was 8-times more likely in patients with subdural haemorrhage ≥10 mm, 5-times more likely with epidural haemorrhage ≥10 mm and 3-times more likely with base deficit ≥4. Forty-seven patients underwent a neurosurgical intervention. Patients with displaced skull fracture were 10-times more likely and patients with base deficit >4 were 21-times more likely to have a neurosurgical intervention., Conclusion: In patients with intracranial injury, a mild GCS score (GCS 13-15) in patients with an intracranial injury does not preclude progression on repeat head CT and the need for a neurosurgical intervention. Base deficit greater than four and displaced skull fracture are the greatest predictors for neurosurgical intervention in patients with mild TBI and an intracranial injury.

- Abstract
Background: To optimize neurosurgical resources, guidelines were developed at our institution, allowing the acute care surgeons to independently manage traumatic intracranial hemorrhage less than or equal to 4 mm. The aim of our study was to evaluate our established Brain Injury Guidelines (BIG 1 category) for managing patients with traumatic brain injury (TBI) without neurosurgical consultation., Methods: We formulated the BIG based on a 4-year retrospective chart review of all TBI patients presenting at our Level 1 trauma center. We then prospectively implemented our BIG 1 category to identify TBI patients that were to be managed without neurosurgical consultation (No-NC). Propensity scoring matched patients with No-NC to a similar cohort of patients managed with NC before the implementation of our BIG in a 1:1 ratio for demographics, severity of injury, and type and size of intracranial hemorrhage. Primary outcome measure was need for neurosurgical intervention and 30-day readmission rates., Results: A total of 254 TBI patients (127 of NC and 127 of No-NC patients) were included in the analysis. The mean (SD) age was 40.8 (22.7) years, 63.4% (n = 161) were male, median Glasgow Coma Scale (GCS) score was 15 (range, 13-15), and median head Abbreviated Injury Scale (AIS) score was 2 (range, 2-3). There was no neurosurgical intervention or 30-day readmission in both the groups. In the No-NC group, 3.9% of the patients had postdischarge emergency department visits compared with 4.7% of the NC group (p = 0.5). All patients were discharged home from the emergency department., Conclusion: We validated our BIG and demonstrated that acute care surgeons can effectively care for minimally injured TBI patients with good outcomes. A national multi-institutional prospective evaluation is warranted., Level of Evidence: Therapeutic/care management, level IV.

- Abstract
Background: Studies have proposed a neuroprotective role for alcohol (ETOH) in traumatic brain injury (TBI). We hypothesized that ETOH intoxication is associated with mortality in patients with severe TBI., Methods: Version 7.2 of the National Trauma Data Bank (2007-2010) was queried for all patients with isolated blunt severe TBI (Head Abbreviated Injury Score ≥4) and blood ETOH levels recorded on admission. Primary outcome measure was mortality. Multivariate logistic regression analysis was performed to assess factors predicting mortality and in-hospital complications., Results: A total of 23,983 patients with severe TBI were evaluated of which 22.8% (n = 5461) patients tested positive for ETOH intoxication. ETOH-positive patients were more likely to have in-hospital complications (P = 0.001) and have a higher mortality rate (P = 0.01). ETOH intoxication was an independent predictor for mortality (odds ratio: 1.2, 95% confidence interval: 1.1-2.1, P = 0.01) and development of in-hospital complications (odds ratio: 1.3, 95% confidence interval: 1.1-2.8, P = 0.009) in patients with isolated severe TBI., Conclusions: ETOH intoxication is an independent predictor for mortality in patients with severe TBI patients and is associated with higher complication rates. Our results from the National Trauma Data Standards differ from those previously reported. The proposed neuroprotective role of ETOH needs further clarification., (Copyright © 2014 Elsevier Inc.

- Abstract
Background: A definitive consensus on the standardization of practice of a routine repeat head CT (RHCT) scan in patients with traumatic intracranial hemorrhage is lacking. We hypothesized that in examinable patients without neurologic deterioration, RHCT scan does not lead to neurosurgical intervention (craniotomy/craniectomy)., Study Design: This was a 3-year prospective cohort analysis of patients aged 18 years and older, without antiplatelet or anticoagulation therapy, presenting to our level 1 trauma center with intracranial hemorrhage on initial head CT and a follow-up RHCT. Neurosurgical intervention was defined by craniotomy/craniectomy. Neurologic deterioration was defined as altered mental status, focal neurologic deficits, and/or pupillary changes., Results: A total of 1,129 patients were included. Routine RHCT was performed in 1,099 patients. The progression rate was 19.7% (216 of 1,099), with subsequent neurosurgical intervention in 4 patients. Four patients had an abnormal neurologic examination, with a Glasgow Coma Scale (GCS) of ≤8 requiring intubation. Thirty patients had an RHCT secondary to neurologic deterioration; 53% (16 of 30) had progression on RHCT, of which 75% (12 of 16) required neurosurgical intervention. There was an association between deterioration in neurologic examination and need for neurosurgical intervention (odds ratio 3.98; 95% CI 1.7 to 9.1). The negative predictive value of a deteriorating neurologic examination in predicting the need for neurosurgical intervention was 100% in patients with GCS > 8., Conclusions: Routine repeat head CT scan is not warranted in patients with normal neurologic examination. Routine repeat head CT scan does not supplement the need for neurologic examination for determining management in patients with traumatic brain injury., (Copyright © 2014 American College of Surgeons.

- Abstract
Background: It is becoming a standard practice that any "positive" identification of a radiographic intracranial injury requires transfer of the patient to a trauma center for observation and repeat head computed tomography (RHCT). The purpose of this study was to define guidelines-based on each patient's history, physical examination, and initial head CT findings-regarding which patients require a period of observation, RHCT, or neurosurgical consultation., Methods: In our retrospective cohort analysis, we reviewed the records of 3,803 blunt traumatic brain injury patients during a 4-year period. We classified patients according to neurologic examination results, use of intoxicants, anticoagulation status, and initial head CT findings. We then developed brain injury guidelines (BIG) based on the individual patient's need for observation or hospitalization, RHCT, or neurosurgical consultation., Results: A total of 1,232 patients had an abnormal head CT finding. In the BIG 1 category, no patients worsened clinically or radiographically or required any intervention. BIG 2 category had radiographic worsening in 2.6% of the patients. All patients who required neurosurgical intervention (13%) were in BIG 3. There was excellent agreement between assigned BIG and verified BIG. κ statistic is equal to 0.98., Conclusion: We have proposed BIG based on patient's history, neurologic examination, and findings of initial head CT scan. These guidelines must be used as supplement to good clinical examination while managing patients with traumatic brain injury. Prospective validation of the BIG is warranted before its widespread implementation., Level of Evidence: Epidemiologic study, level III.

- Abstract
Coagulopathy is a defined barrier for organ donation in patients with lethal traumatic brain injuries. The purpose of this study was to document our experience with the use of prothrombin complex concentrate (PCC) to facilitate organ donation in patients with lethal traumatic brain injuries. We performed a 4-year retrospective analysis of all patients with devastating gunshot wounds to the brain. The data were analyzed for demographics, change in international normalized ratio (INR), and subsequent organ donation. The primary end point was organ donation. Eighty-eight patients with lethal traumatic brain injury were identified from the trauma registry of whom 13 were coagulopathic at the time of admission (mean INR 2.2 ± 0.8). Of these 13 patients, 10 patients received PCC in an effort to reverse their coagulopathy. Mean INR before PCC administration was 2.01 ± 0.7 and 1.1 ± 0.7 after administration (P < 0.006). Correction of coagulopathy was attained in 70 per cent (seven of 10) patients. Of these seven patients, consent for donation was obtained in six patients and resulted in 19 solid organs being procured. The cost of PCC per patient was $1022 ± 544. PCC effectively reveres coagulopathy associated with lethal traumatic brain injury and enabled patients to proceed to organ donation. Although various methodologies exist for the treatment of coagulopathy to facilitate organ donation, PCC provides a rapid and cost-effective therapy for reversal of coagulopathy in patients with lethal traumatic brain injuries.

- Abstract
Background: Patients receiving antiplatelet medications are considered to be at an increased risk for traumatic intracranial hemorrhage after blunt head trauma. However, most studies have categorized all antiplatelet drugs into one category. The aim of our study was to evaluate clinical outcomes and the requirement of a repeat head computed tomography (RHCT) in patients on preinjury clopidogrel therapy., Methods: Patients with traumatic brain injury with intracranial hemorrhage on initial head CT were prospectively enrolled. Patients on preinjury clopidogrel were matched with patients exclusive of antiplatelet and anticoagulation therapy using a propensity score in a 1:1 ratio for age, Glasgow Coma Scale (GCS), head Abbreviated Injury Scale (h-AIS), Injury Severity Score (ISS), neurologic examination, and platelet transfusion. Outcome measures were progression on RHCT scan and need for neurosurgical intervention., Results: A total of 142 patients with intracranial hemorrhage on initial head CT scan (clopidogrel, 71; no clopidogrel, 71) were enrolled. The mean (SD) age was 70.5 (15.1) years, 66% were male, median GCS score was 14 (range, 3-15), and median h-AIS (ISS) was 3 (range, 2-5). The mean (SD) platelet count was 210 (101), and 61% (n = 86) of the patients received platelet transfusion. Patients on preinjury clopidogrel were more likely to have progression on RHCT (odds ratio [OR], 5.1; 95% confidence interval [CI], 3.1-7.1) and RHCT as a result of clinical deterioration (OR, 2.1; 95% CI, 1.8-3.5). The overall rate of neurosurgical intervention was 4.2% (n = 6). Patients on clopidogrel therapy were more likely to require a neurosurgical intervention (OR, 1.8; 95% CI, 1.4-3.1)., Conclusion: Preinjury clopidogrel therapy is associated with progression of initial insult on RHCT scan and need for neurosurgical intervention. Preinjury clopidogrel therapy as an independent variable should warrant the need for a routine RHCT scan in patients with traumatic brain injury., Level of Evidence: Prognostic study, level I; therapeutic study, level II.

- Abstract
Anticoagulation agents are proven risk factors for intracranial hemorrhage (ICH) in traumatic brain injury (TBI). The aim of our study is to describe the epidemiology of prehospital coumadin, aspirin, and Plavix (CAP) patients with ICH and evaluate the use of repeat head computed tomography (CT) in this group. We performed a retrospective study from our trauma registry. All patients with intracranial hemorrhage on initial CT with prehospital CAP therapy were included. Demographics, CT scan findings, number of repeat CT scans, progressive findings, and neurosurgical intervention were abstracted. A comparison between prehospital CAP and no-CAP patients was done using χ(2) and Mann-Whitney U test. A total of 1606 patients with blunt TBI charts were reviewed of whom 508 patients had intracranial bleeding on initial CT scan and 72 were on prehospital CAP therapy. CAP patients were older (P < 0.001), had higher Injury Severity Score and head Abbreviated Injury Scores on admission (P < 0.001), were more likely to present with an abnormal neurologic examination (P = 0.004), and had higher hospital and intensive care unit lengths of stay (P < 0.005). Eighty-four per cent of patients were on antiplatelet therapy and 27 per cent were on warfarin. The CAP patients have a threefold increase in the rate of worsening repeat head CT (26 vs 9%, P < 0.05). Prehospital CAP therapy is high risk for progression of bleeding on repeat head CT. Routine repeat head CT remains an important component in this patient population and can provide useful information.

- Abstract
Background: Most studies have categorized all antiplatelet drugs into one category. The aim of our study was to evaluate the utility of repeat head computed tomography (RHCT) and outcomes in patients on low-dose aspirin (acetylsalicylic acid; ASA) therapy., Methods: Patients with traumatic brain injury with intracranial hemorrhage on initial head computed tomography (CT) were prospectively enrolled. Patients on prehospital low-dose (81 mg) aspirin therapy were matched with patients exclusive of antiplatelet and anticoagulation therapy using propensity score matching in a 1:1 ratio for age, Glasgow Coma Scale, head Abbreviated Injury Scale score, Injury Severity Score, and neurological examination. Outcome measures were progression on RHCT and subsequent neurosurgical intervention., Results: A total of 144 patients who had intracranial hemorrhage on initial CT scan (ASA group: 72; No-ASA group: 72) were enrolled. The mean age was 72.8 ± 11.7 years, 59.7% were male, and median head Abbreviated Injury Scale was 3 (2-3). There was no difference in progression on RHCT (25% in ASA versus 16.6% in no-ASA), change in management as a result of RHCT (1.4% versus 1.4%), RHCT as a result of neurological decline (0 versus 1.4%), discharge Glasgow Coma Scale (15 [14-15] versus 15 [14-15]), and mortality (0 versus 1.4%) between the two groups., Conclusions: Low-dose aspirin therapy is not associated with progression of initial insult on RHCT or clinical deterioration. Prehospital low-dose aspirin therapy as a sole criterion should not warrant a routine repeat head CT in traumatic brain injury., (Published by Elsevier Inc.)

- Abstract
Background: Coagulopathy is a major determinant of disability and death in patients with traumatic intracranial hemorrhage. However, the correlation between coagulopathy defined by routine coagulation tests and clinical outcomes in traumatic brain injury (TBI) is not well defined. The aim of our study was to determine the effect of coagulopathy diagnosed by routine laboratory tests on outcomes in TBI patients., Methods: We performed a retrospective cohort analysis of all isolated TBI patients exclusive of prehospital antiplatelet and anticoagulants with coagulation tests, namely, international normalized ratio (INR), platelet count, and partial thromboplastin time at admission. We defined coagulopathy by an INR of 1.5 or greater, partial thromboplastin time of 35 or greater, or platelet count of 100 × 10(3)/µL or less. Outcome measures were progression on repeat head computed tomography (RHCT), need for neurosurgical intervention, and mortality., Results: A total of 591 patients were enrolled, with a mean (SD) age of 47.4 (26.5) years and 67% being male. Of the patients, 13.3% were coagulopathic at admission. Platelet count of 100 × 10(3)/µL or less was an independent predictor of progression on RHCT (odd ratio [OR], 4; 95% confidence interval [CI], 1.7-10), need for neurosurgical intervention (OR, 3.6; 95% CI, 1.2-6.1), and mortality (OR, 2.6; 95% CI, 1.1-4.8). INR was an independent predictor of progression on RHCT (OR, 2; 95% CI, 1.1-4.3)., Conclusion: Routine bedside coagulation parameters at admission play an important role in predicting outcomes in blunt TBI. Platelet count is the strongest predictor for progression of initial insult on RHCT, need for neurosurgical intervention, and mortality., Level of Evidence: Prognostic study, level III.

- Abstract
Background: Opinion is divided on the role of routine repeat head computed tomography (RHCT) for guiding clinical management in pediatric patients with blunt head trauma. We hypothesize that routine RHCT does not lead to change in management in mild and moderate traumatic brain injury (TBI)., Methods: This is a 3-year retrospective study of all patients of age 2 years to 18 years with blunt TBI admitted to our Level 1 trauma center with an abnormal head CT. Indications for RHCT (routine vs. neurologic deterioration) and their findings (progression or improvement) were recorded. Neurosurgical intervention was defined as extraventricular drain placement, craniectomy, or craniotomy. Primary outcome was a change in management after RHCT., Results: A total of 291 pediatric patients were identified; of which 191 patients received an RHCT. Routine RHCT did not lead to neurosurgical intervention in the mild and moderate TBI group. In patients who received RHCT due to neurologic decline (n = 7), radiographic progression was seen on 85% of the patients (n = 6), with subsequent neurosurgical interventions in three patients. Two of these patients had a Glasgow Coma Scale (GCS) score of less than 8 at admission., Conclusion: Our study showed that the neurologic examination can be trusted and is reliable in pediatric blunt TBI patients in determining when an RHCT scan is necessary. We recommend that RHCT is required routinely in patients with intracranial hemorrhage with GCS score of 8 or less and in patients with GCS greater than 8 and that RHCT be performed only when there are clinical indications., Level of Evidence: Diagnostic/therapeutic study, level IV.

- Abstract
Background: Neurosurgical services are a limited resource and effective use of them would improve the health care system. Acute care surgeons (ACS) are accustomed to treating mild traumatic brain injury (TBI) including those with minor radiographic intracranial injuries. We hypothesized that ACS safely manage mild TBI with intracranial hemorrhage (ICH) on head computed tomographic (CT) scan without neurosurgical consultation (NC)., Methods: We performed a retrospective analysis on all TBI patients with positive findings on head CT scan managed without NC during a 2-year period. Propensity scoring matched NC to no-NC patients on a 1:2 ratio for Glasgow Coma Scale (GCS) score, head Abbreviated Injury Scale (h-AIS) score, neurological examination, age, Injury Severity Score (ISS), findings of initial head CT scan including type and size of ICH., Results: A total of 270 patients with mild TBI and positive CT scan findings were included (90 with NC and 180 without NC). Sixty-three percent were male, and mean (SD) age was 39 (25) years. The median GCS was 15 (13-15), and the h-AIS score was 2 (1-3). In both groups, there was no neurosurgical intervention, in-hospital mortality, or 30-day readmission. In the no-NC group, 8% of the patients had postdischarge emergency department (ED) visits compared with 4% of the NC group (p = 0.5). All patients with postdischarge ED visits in both groups were discharged home from the ED., Conclusion: ACS can manage mild TBI with ICH without obtaining an inpatient NC. Further guidelines should be established to help identify which patients meet criteria to be safely managed without NC., Level of Evidence: Care management/therapeutic study, level IV.

- Abstract
Background: Coagulopathy in patients with traumatic brain injury (TBI) is a well-studied concept. Prothrombin complex concentrate (PCC) has been shown to be an effective treatment modality for correction of TBI coagulopathy. However, its use and effectiveness compared with recombinant factor VII (rFVIIa) in TBI has not been established. The purpose of this study was to compare PCC and rFVIIa for the correction of TBI coagulopathy., Methods: All patients with a TBI and an induced or acquired coagulopathy whom received rFVIIa or PCC at our Level I trauma center during a 4-year period were reviewed. Data collected included demographics, changes in international normalized ratio and blood products transfusion, craniotomy rates, and time to neurosurgical intervention, thromboembolic complications, and mortality differences., Results: The study was composed of 85 TBI patients, of whom 64 patients received PCC while 21 patients received rFVIIa. PCC group were more likely to be on coumadin (44% vs. 14%, p = 0.01). There was a significant decline in packed red blood cell transfusion and fresh frozen plasma after PCC administration (p < 0.01). There was no statistically significant difference in the craniotomy rate (28% vs. 10 %, p = 0.1) or the mean time to intervention between the two groups (201 [33] vs. 230 [10], p = 0.9). Mortality rates were lower in the PCC group compared with rFVIIa (67% vs. 47%, p = 0.02). Subsequent thromboembolic event was seen in one patient on rFVIIa. Mean cost of treatment per patient on PCC was $1,007 compared with $5,757 for rFVIIa (p < 0.01)., Conclusion: PCC is safe and effective for treating coagulopathy in TBI patients, while reducing costs and resource use. PCC should be considered as an effective therapy to treat both acquired and induced coagulopathy in TBI with or without prehospital coumadin use., Level of Evidence: Therapeutic study, level IV.

Background: Gunshot wounds to the brain are the most lethal of all firearm injuries, with reported survival rates of 10% to 15%. The aim of this study was to determine outcomes in patients with gunshot wounds to the brain, presenting to our institution over time. We hypothesized that aggressive management can increase survival and the rate of organ donation in patients with gunshot wounds to the brain. Study Design: We analyzed all patients with gunshot wounds to the brain presenting to our level 1 trauma center over a 5-year period. Aggressive management was defined as resuscitation with blood products, hyperosmolar therapy, and/or prothrombin complex concentrate (PCC). The primary outcome was survival and the secondary outcome was organ donation. Results: There were 132 patients with gunshot wounds to the brain, and the survival rates increased incrementally every year, from 10% in 2008 to 46% in 2011, with the adoption of aggressive management. Among survivors, 40% (16 of 40) of the patients had bi-hemispheric injuries. Aggressive management with blood products (p = 0.02) and hyperosmolar therapy (p = 0.01) was independently associated with survival. Of the survivors, 20% had a Glasgow Coma Scale score ≥ 13 at hospital discharge. In patients who died (n = 92), 56% patients were eligible for organ donation, and they donated 60 organs. Conclusions: Aggressive management is associated with significant improvement in survival and organ procurement in patients with gunshot wounds to the brain. The bias of resource use can no longer be used to preclude trauma surgeons from abandoning aggressive attempts to save patients with gunshot wound to the brain. [ABSTRACT FROM AUTHOR]
