ABSTRACT

Introduction The relationship between cigarette smoking and arterial carboxyhemoglobin (CoHb) in trauma activation patients has not been investigated. The aim was to determine if cigarette smoking is associated with drug abuse history and arterial CoHb levels. Methodology This is a retrospective review of level I trauma center activations aged 18-60 during 2018-2020. A medical record audit was performed to assess each patient's cigarette smoking and drug abuse history and admission arterial CoHb level. The CoHb levels and smoking history for each patient were used to construct a receiver operating characteristic curve. Results Of the 742 trauma activations aged 18-60, 737 (99.3%) had a documented cigarette smoking history. Smoking history was positive in 49.7% (366) and negative in 50.3% (371). The positive smoking proportion was greater in patients with a drug abuse history (63.9% (234/366)) than those with a negative history (31.0% (115/371); p<0.0001; odds ratio=4.0). In 717 patients with a CoHb value, the CoHb was higher in smokers (3.9±2.2%) than in non-smokers (0.5±0.4%; p<0.0001; Cohen d=2.2). A CoHb >1.5% was higher in smokers (93.3% (333/357)) than non-smokers (1.7% (6/360); p<0.0001; odds ratio=818.6). The receiver operating characteristic curve for the relationship between CoHb and cigarette smoking history showed an area under the curve of 0.980 (p<0.0001). Using an arterial CoHb level >1.5% to predict a positive smoking history and a CoHb level ≤1.5% to predict a non-smoking history, sensitivity was 93.3% (333/357), specificity was 98.3% (354/360), and accuracy was 95.8% (687/717). Conclusion Cigarette smoking in trauma activations aged 18-60 is associated with drug abuse history and increased arterial CoHb levels on trauma center arrival.

ABSTRACT

Background Numerous investigators have shown that early postinjury Glasgow Coma Scale (GCS) values are associated with later clinical outcomes in patients with traumatic brain injury (TBI), in-hospital mortality, and post-hospital discharge Glasgow Outcome Scale (GOS) results. Following TBI, early GCS, and brain computed tomography (CT) scores have been associated with clinical outcomes. However, only one previous study combined GCS scores with CT scan results and demonstrated an interaction with in-hospital mortality and GOS results. We aimed to determine if interactive GCS and CT findings would be associated with outcomes better than GCS and CT findings alone. Methodology Our study included TBI patients who had GCS scores of 3-12 and required mechanical ventilation for ≥five days. The GCS deficit was determined as 15 minus the GCS score. The mass effect CT score was calculated as lateral ventricular compression plus basal cistern compression plus midline shift. Each value was 1 for present. A prognostic CT score was the mass effect score plus subarachnoid hemorrhage (2 if present).The CT-GCS deficit score was the sum of the GCS deficit and the prognostic CT score. Results One hundred and twelve consecutive TBI patients met the inclusion criteria. Patients with surgical decompression had a lower GCS score (6.0±3.0) than those without (7.7±3.3; Cohen d=0.54). Patients with surgical decompression had a higher mass effect CT score (2.8±0.5) than those without (1.7±1.0; Cohen d=1.4). The GCS deficit was greater in patients not following commands at hospital discharge (9.6±2.6) than in those following commands (6.8±3.2; Cohen d=0.96). The prognostic CT score was greater in patients not following commands at hospital discharge (3.7±1.2) than in those following commands (3.1±1.1; Cohen d=0.52). The CT-GCS deficit score was greater in patients not following commands at hospital discharge (13.3±3.2) than in those following commands (9.9±3.2; Cohen d=1.06). Logistic regression stepwise analysis showed that the failure to follow commands at hospital discharge was associated with the CT-GCS deficit score but not with the GCS deficit. The GCS deficit was greater in patients not following commands at three months (9.7±2.8) than in those following commands (7.4±3.2; Cohen d=0.78). The CT-GCS deficit score was greater in patients not following commands at three months (13.6±3.1) than in those following commands (10.5±3.4; Cohen d=0.94). Logistic regression stepwise analysis showed that failure to follow commands at three months was associated with the CT-GCS deficit score but not with the GCS deficit. The proportion not following commands at three months was greater with a GCS deficit of 9-12 (50.9%) than with a GCS deficit of 3-8 (21.1%; odds ratio=3.9; risk ratio=2.1). The proportion of not following commands at three months was greater with a CT-GCS deficit score of 13-17 (56.0%) than with a CT-GCS deficit score of 4-12 (18.3%; OR=5.7; RR=3.1). Conclusion The mass effect CT score had a substantially better association with the need for surgical decompression than did the GCS score. The degree of association for not following commands at hospital discharge and three months was greater with the CT-GCS deficit score than with the GCS deficit. These observations support the notion that a mass effect and subarachnoid hemorrhage composite CT score can interact with the GCS score to better prognosticate TBI outcomes than the GCS score alone.

ABSTRACT

There has been little effort to identify an overall occurrence of numerous cerebral white matter hyperintensities (NCWMH) on relevant brain magnetic resonance imaging (MRI) sequences in postinjury cerebral fat embolism syndrome (CFES) patients. Also, quantification of pre-CFES cognitive status, degree of neurologic deterioration, and presence of a skeletal fracture with CFES is nominal. The authors performed a PubMed search and identified 24 relevant manuscripts. Two case reports from the authors' institution were also used. The presence of NCWMH was assessed by reviewing T2-weighted image (T2WI), diffusion-weighted image (DWI), fluid-attenuated inversion recovery (FLAIR) figures and captions, and by evaluating manuscript descriptions. When pre-CFES cognitive status was described, it was categorized as Glasgow Coma Scale (GCS) score = 14-15 (yes or no). When the degree of neurologic deterioration was noted with CFES, it was classified as coma or GCS ≤ 8 (yes or no). When skeletal fractures were itemized, they were categorized as yes or no. The total number of CFES patients was 133 (literature search was 131 and two author-described case reports). Of the 131 patients with manuscript MRI figures or descriptive statements, 120 (91. 6%) had NCWMH. Of 63 patients with a delineation of the MRI sequence, NCWMH appeared on DWI in 24, on T2WI in 57, and on FLAIR in 10 patients. Pre-CFES cognitive status was GCS 14-15 in 93.5% (58/62) of the patients. The CFES neurologic deterioration was coma or GCS ≤ 8 in 52.5% (62/118) of the patients. A skeletal fracture was present in 99.0% (101/102) of the CFES patients. The presence of NCWMH in trauma patients with hospital-acquired neurologic deterioration and the presence of a skeletal fracture is consistent with CFES.

ABSTRACT

BACKGROUND: Unlike prior guidelines for a positive toxicology screen, the 2022 national trauma data bank dictionary requires the exclusion of postinjury drugs. We aimed to (1) investigate the proportion of drugs in the toxicology screen that were given postinjury; (2) determine preinjury toxicology-positive associations with smoking, psychiatric, and drug abuse histories in an activation patient (ACT-Pt) cohort; and (3) explore whether ACT-Pt varied toxicology testing rates would produce similar preinjury toxicology-positive results. METHODS: In this retrospective study, the historic parent database included consecutive trauma center admissions where toxicology testing was discretionary. A supplementary electronic medical record audit of ACT-Pts age 18-60 years assessed smoking, psychiatric, and drug abuse histories. Subsequently, ACT-Pt age 18-100 years testing was encouraged by attending surgeons and, later routine testing was implemented. RESULTS: Of 2,076 patients in the historic parent database, discretionary toxicology testing occurred in 23.9% (n = 496) and the positive proportion was 58.9% (n = 292). However, 23.6% (n = 69) of the positive screens had the drug given postinjury. The preinjury positive-toxicology proportion was 45.0% (223/496). Preinjury toxicology positivity was greater in ACT-Pts age 18-60 years (52.3%) than in other patients (activations >60 years of age or consultations) (33.7%; p < 0.0001; odds ratio [OR] = 2.2). Smoking, psychiatric, and drug abuse histories were more common in ACT-Pts age 18-60 years preinjury toxicology-positive patients (74.4%, 51.3%, and 98.7%) than in negative patients (36.6%, 25.2%, and 25.2%; p < 0.0001). In ACT-Pts age 18-100 years, when compared to historic discretionary testing (32.7%), testing was increased with encouraged testing (62.1%; p < 0.0001; OR = 3.4) and routine testing (73.1%; p < 0.0001; OR = 5.6). ACT-Pt preinjury toxicology positivity was similar for historic discretionary (47.9%), encouraged (57.6%), and routine (51.3%) (p = 0.3670) testing. The meta-analytic toxicology-positive proportion for the three testing strategies was 49.8%. CONCLUSIONS: Substantial toxicology-positive findings are due to postinjury drug administration. Toxicology positivity is associated with ACT-Pts age 18-60 years and smoking, psychiatric, and drug abuse histories. ACT-Pt age 18-100 years preinjury toxicology positivity is 50% and does not vary with different testing proportions and strategies.

ABSTRACT

BACKGROUND: Changes in injury patterns during the COVID pandemic have been reported in other states. The objective was to explore changes to trauma service volume and admission characteristics at a trauma center in northeast Ohio during a stay-at-home order (SAHO) and compare the 2020 data to historic trauma census data. METHODS: Retrospective chart review of adult trauma patients admitted to a level I trauma center in northeast Ohio. Trauma admissions from January 21 to July 21, 2020 (COVID period) were compared to date-matched cohorts of trauma admissions from 2018 to 2019 (historic period). The COVID period was further categorized as pre-SAHO, active-SAHO, and post-SAHO. RESULTS: The SAHO was associated with a reduction in trauma center admissions that increased after the SAHO (P = .0033). Only outdoor recreational vehicle (ORV) injuries (P = .0221) and self-inflicted hanging (P = .0028) mechanisms were increased during the COVID period and had substantial effect sizes. Glasgow Coma Scores were lower during the COVID period (P = .0286) with a negligible effect size. Violence-related injuries, injury severity, mortality, and admission characteristics including alcohol and drug testing and positivity were similar in the COVID and historic periods. DISCUSSION: The SAHO resulted in a temporary decrease in trauma center admissions. Although ORV and hanging mechanisms were increased, other mechanisms such as alcohol and toxicology proportions, injury severity, length of stay, and mortality were unchanged.

ABSTRACT

Because few studies have assessed blood alcohol concentration (BAC)-positive risk conditions in trauma activation patients, this retrospective investigation pursued such an analysis. The parent database included consecutive trauma center admissions from January 21 to July 21 for 2018-2020. The supplementary electronic medical record audit of trauma activation patients aged 18-60 years (TA18-60) assessed alcohol misuse, smoking history, and serum bicarbonate levels. An alcohol misuse risk score was created by assigning a value of 0 (no) or 1 (yes) for each risk condition: 1) smoking history, 2) BAC-positive status, 3) BAC ≥ 100 mg/dL with Glasgow Coma Scale score (GCS) ≥ 13, 4) age ≥ 40 years, and 5) bicarbonate level ≥ 20 mmol/L in BAC-positive patients and summing the total score (range, 0-5). Of 2,076 patients, BAC testing occurred in 60.9% (n = 1,265). BAC positivity was greater in TA18-60 (36.9%) than in other patients (20.8%; P < 0.0001; odds ratio [OR] = 2.2). In the TA18-60 audit (n = 742), categorizations were available for BAC status, 98.5%; smoking history, 99.3%; alcohol misuse history, 99.5%; and bicarbonate level, 99.5%. BAC positivity was greater in smokers (41.3%) than in non-smokers (31.5%; P = 0.0061; OR = 1.5). BAC positivity was greater with alcohol misuse (87.0%) than without (17.7%; P < 0.0001; OR = 31.2). BAC-positive was associated with a greater proportion of bicarbonate levels < 20 mmol/L (52.0%) than BAC-negative (31.8%; P < 0.0001; OR = 2.3). The alcohol misuse proportion was greater with an alcohol misuse risk score of 3-5 (74.4% [142/191]) than with a risk score of 0-2 (10.4% [57/546]; P < 0.0001; OR = 24.9; area under the receiver operating characteristic curve = 0.89). This retrospective study demonstrates that BAC positivity is associated with TA18-60, smoking and alcohol misuse histories, and metabolic acidosis. An alcohol misuse history is associated with multiple risk conditions. Trauma center leadership should provide procedures to identify patients who are BAC-positive or have a positive smoking or alcohol misuse history. Then, such patients should be referred to care providers who can offer assistance and guidance for enhancing overall patient wellbeing.

ABSTRACT

PURPOSE: Necrotizing fasciitis (NF) is a life-threatening infection that involves spreading necrosis of the subcutaneous tissue and fascia that affects the extremities, abdominal wall, and perineum. Primary infection of the breast is a rare occurrence. Shah et al described the first case of primary breast NF and recommended radical "pseudotumor" excision and delayed skin closure months after resolution. Numerous other cases reported were successfully managed with different strategies. We aimed to summarize management options for primary breast NF through a systematic review of the literature. METHODS: A systematic review of English literature was performed using PubMed. A total of 58 abstracts were reviewed. Data were abstracted from 25 cases that met inclusion criteria. RESULTS: A total of 25 cases of primary NF of the breast without an inciting event were found within the literature. Common initial operations included total mastectomy (36.0%), excisional debridement (32.0%), and partial mastectomy (12.0%). A total or radical mastectomy was completed for definitive source control in 13 (52.0%) cases. A total of 18 cases underwent reconstruction. Split-thickness skin grafts (44.4%) and delayed primary closures (33.3%) were the most common methods of reconstruction. CONCLUSION: Majority of cases with primary breast NF are managed with a total mastectomy to gain source control. Reconstruction using split-thickness skin grafts was most common. Other options included delayed primary closure, full thickness skin grafts, local tissue rearrangement, and pedicle flap reconstruction. Reconstruction should be patient dependent, but the whole arsenal of the reconstructive ladder may be used.


OBJECTIF: La fasciite nécrosante (FN) est une infection au potentiel fatal responsable d'une nécrose croissante des tissus sous-cutanés et du fascia et qui touche les membres, la paroi abdominale et le périnée. L'infection primaire du sein est rare. Shah et coll. ont décrit le premier cas de FN primaire du sein, ont recommandé une excision radicale de la « pseudotumeur ¼ et ont reporté la fermeture cutanée pendant des mois après la résolution. La prise en charge de nombreux autres cas déclarés a été positive grâce à diverses stratégies. Les chercheurs souhaitaient résumer les possibilités de prise en charge de la FN primaire du sein à l'aide d'une analyse systématique des publications scientifiques. MÉTHODOLOGIE: Les chercheurs ont procédé à une analyse systématique des publications anglophones dans PubMed. Ils ont examiné un total de 58 résumés et colligé les données de 25 cas qui respectaient les critères d'inclusion. RÉSULTATS: Au total, les chercheurs ont extrait 25 cas de FN primaire du sein non précédés d'un événement incitatif. Les opérations initiales courantes incluaient une mastectomie totale (36,0 %), un débridement excisionnel (32,0 %) et une mastectomie partielle (12,0 %). Dans 13 cas (52,0 %), les chercheurs ont constaté une mastectomie totale ou radicale pour assurer le contrôle définitif de la source. Au total, 18 cas ont subi une reconstruction. Les greffes dermo-épidermiques (44,4 %) et le report des fermetures primaires (33,3 %) constituaient les principales méthodes de reconstruction. CONCLUSION: La majorité des cas de FN primaire du sein étaient pris en charge par une mastectomie totale pour parvenir à contrôler la source. La reconstruction par greffe dermo-épidermique était la plus courante. Parmi les autres options, soulignons le report de la fermeture primaire, la greffe dermo-épidermique pleine épaisseur, la réorganisation tissulaire locale et la reconstruction du lambeau pédiculaire. La reconstruction doit être adaptée à chaque patiente, mais peut faire appel à tout l'arsenal de l'échelle de reconstruction.

ABSTRACT

BACKGROUND: Given the frequency, severity, and attention of traumatic brain injury in children, benchmarking disparities and injury characteristics for adolescent patients is pivotal in understanding and enhancing both clinical care and outcomes. OBJECTIVES: The purpose of this study was to investigate racial disparities on mechanism of injury, clinical outcomes, and social-health factors among adolescents treated in the emergency department (ED) for a head, neck, or brain injury. METHODS: This study is the result of a retrospective chart review of head-, neck-, and brain-injured adolescent patients (n = 2857) treated at three community hospital EDs and one stand-alone ED. Outcome measures included patient demographics (gender, race/ethnicity, age), Glasgow Coma Scale score, hospital length of stay, intensive care unit length of stay, mechanism of injury, primary diagnosis, secondary diagnosis of a concussion, ventilation days, discharge disposition, and primary insurance. RESULTS: There were racial differences in primary diagnosis, mechanism of injury, and insurance status. Results indicated that a higher proportion of white patients were diagnosed with a concussion compared with black patients (p < 0.001). Moreover, a higher proportion of white patients were seen in the ED for head, neck, or brain injury as a result of a sports or motor vehicle incident, whereas a leading mechanism among black patients was assault (p = 0.01). More white patients had private insurance, whereas more black patients had Medicaid (p < 0.001). CONCLUSION: The disparities in mechanisms for which black and white adolescent patients are seeking care at the ED for head, neck, or brain injury help to identify social-health risks of sustaining a head, neck, or brain injury. These racial disparities between black and white adolescents seen at the ED for head, neck, or brain injury suggest the need for further research to better understand the national representation of these disparities.

ABSTRACT

INTRODUCTION: There is controversy regarding obesity or body mass index (BMI) effects on postinjury mortality and mechanical ventilation. The aim was to assess outcome associations with BMI and postinjury blood glucose and cholesterol. METHOD: Adult blunt traumatic brain injury patients admitted to a level I trauma center and requiring ≥ 3 days of intensive care were investigated. Admission blood glucose and day-4 total cholesterol were captured from the medical records. Cholesterol ratio was calculated by dividing day-4 values by published national normative levels according to sex, age, and injury date. RESULTS: The parent cohort included 588 patients. The ventilator days ≥ 10 or died group, when compared to the ventilator days < 10 and lived group, had higher Injury Severity Score (ISS) (29.2±9.9 versus [vs.] 23.7±9.7, P < 0.0001), BMI (27.9±6.8 vs. 26.0±5.5, P = 0.0002), and admission glucose (182.6±79 vs. 155.4±59 mg/dl, P < 0.0001, n = 476) and lower emergency department Glasgow Coma Scale score (ED GCS) (6.9±4.7 vs. 10.3±5.0, P < 0.0001) and cholesterol ratio (0.64±0.2 vs. 0.70±0.2, P = 0.0018, n = 364). The ventilator days ≥ 10 or died group had independent associations with increased ISS (P = 0.0709), decreased ED GCS (P = 0.0078), and increased BMI÷cholesterol ratio (P = 0.0003). The ventilator days ≥ 10 or died group had independent associations with increased ISS (P = 0.0013), decreased ED GCS (P < 0.0001), and increased BMI × glucose (P < 0.0001). Ventilator days were increased with higher ISS (P < 0.0001), BMI (P = 0.0014) and glucose (P = 0.0031) and with lower ED GCS (P < 0.0001) and cholesterol ratio (P = 0.0004). Ventilator days had independent associations with increased ISS (P < 0.0001), decreased ED GCS (P = 0.0041), and increased BMI÷cholesterol ratio (P = 0.0010). Ventilator days had independent associations with increased ISS (P < 0.0001), decreased ED GCS (P < 0.0001), and increased BMI × glucose (P = 0.0041). CONCLUSION: For TBI patients, valid risk assessment measurements include ISS (anatomic injury burden), ED GCS (brain function), BMI (preinjury weight status), admission glucose (postinjury metabolism), and day-4 cholesterol ratio (postinjury inflammation).

ABSTRACT

BACKGROUND: There is debate regarding routine repeat head computed tomography (CT) in blunt trauma patients on a pre-injury antithrombotic when the initial CT is negative for intracranial hemorrhage (ICH). DATA SOURCES: Retrospective chart review and systematic literature review with meta-analysis. CONCLUSIONS: In the chart review, 32.1% did not have a repeat head CT and 67.9% did. The delayed ICH incidence between those with and without a repeat head CT was similar (1.7% vs 0, p = .3101). The current study was combined with the identified 24 studies. Delayed ICH with or without routine repeat CT was similar between antiplatelet and anticoagulant categories (1.4% vs. 1.3%, p = .5322). Delayed ICH was lower for patients without routine repeat CT compared to those with routine repeat CT (0.8% vs 1.7%, p = .0008). For this patient population, repeat scans should be discretionary. Routine repeat CT may identify a larger proportion of minor delayed ICH.

ABSTRACT

Although hypertonic saline (HTS) decreases intracranial pressure (ICP) with traumatic brain injury (TBI), its effects on survival and post-discharge neurologic function are less certain. We assessed the impact of HTS administration on TBI outcomes and hypothesized that favorable outcomes would be associated with larger amounts of 3% saline. This is a retrospective study of consecutive-patients with the following criteria: blunt trauma, age 18-70 years, intracranial hemorrhage, Glasgow Coma Scale score (GCS) 3-12, and mechanical ventilation ≥ 5 days. The need for craniotomy or craniectomy denoted surgical decompression patients. Amounts of HTS were during the first-5 trauma center days. Traits for the 112 patients during 2012-2016 were as follows: GCS, 6.8 ± 3.2; subdural hematoma, 71.4%; cerebral contusion, 31.3%, ICP device, 47.3%; surgical decompression, 51.8%; ventilator days, 14.8 ± 6.7; trauma center mortality, 13.4%; and no commands at 3 months 35.5%. In surgically decompressed patients, trauma center mortality was greater with ≤ 8.0 mEq/kg sodium (38.9%) than with > 8.0 mEq/kg (7.5%; P = 0.0037). In surgically decompressed patients, following commands at 3 months was greater with ≥ 1400 mEq sodium (76.9%) than with < 1400 mEq (50.0%; P = 0.0489). For trauma center surviving non-decompression patients with no ICP device, those following commands at 3 months received more sodium (513 ± 784 mEq) than individuals not following commands (82 ± 144 mEq; P = 0.0142). For patients with a GCS 5-8, following commands at 3 months was greater with ≥ 1350 mEq sodium (92.3%) than with < 1350 mEq (60.0%; P = 0.0214). In patients with subdural hematoma or cerebral contusion, following commands at 3 months was greater with ≥ 1400 mEq sodium (84.2%) than with < 1400 mEq (61.8%; P = 0.0333). Patients with ICP > 20 mmHg for ≤ 10 hours (mean hours 2.0) received more sodium (16.5 ± 11.5 mEq/kg) when compared to ICP elevation for ≥ 11 hours (mean hours 34) (9.4 ± 6.3 mEq/kg; P = 0.0139). These observations demonstrate that hypertonic saline administration in patients with complex traumatic brain injury is associated with 1) mitigation of intracranial hypertension, 2) trauma center survival, and 3) following commands at 3 months post-injury.

ABSTRACT

Necrotizing fasciitis (NF) of the breast is a rare occurrence that is routinely misdiagnosed as an abscess or cellulitis, resulting in treatment delays. A total mastectomy is required when delays occur. We present a 53-year-old female with breast NF managed with a partial mastectomy and local tissue rearrangement.

ABSTRACT

BACKGROUND: In 2014, this group published an investigation of surgical patients from 2012 who had substantial rates of postoperative hypoxemia (POH) and perioperative pulmonary aspiration (POPA). Therefore, we investigated whether intraoperative reverse Trendelenburg positioning (RTP) decreases POH and POPA rates. METHODS: Consecutive ASA I-IV surgical patients who had preoperative pulmonary stability requiring general anesthesia with endotracheal intubation were evaluated. Using pulse oximetry, hypoxemia was documented intraoperatively and during the 48 h following PACU discharge. POPA was the presence of a pulmonary infiltrate with hypoxemia. In early 2015, a multifaceted effort was undertaken to enhance anesthesiologist and operating nurse awareness of RTP to potentially decrease POH and POPA rates. Analyses included (1) combining 2012 and 2015 cohorts to assess risk conditions, (2) comparing post-campaign 2015 (increased RTP) and 2012 cohorts, and (3) comparing 2015 patients with audit-documented RTP during surgery to the other 2015 patients. RESULTS: Combining the 500 patients in 2012 with the 1000 in 2015 showed that POH had increased mortality (2.3%), compared to no POH (0.2%; p = 0.0004). POH had increased postoperative length of stay (LOS) (4.6 days), compared to no POH (2.0 days; p < 0.0001). POPA had increased mortality (7.7%) and LOS (8.8 days), compared to no POPA (0.4%; p = 0.0004; 2.3 days; p < 0.0001). Open aortic, cranial, laparotomy, and neck procedures had greater POH (41.3%) and LOS (4.0 days), compared to other procedures (16.3%; p < 0.0001; 2.2 days; p < 0.0001). Glycopyrrolate on induction had lower POH (17.4%) and LOS (1.9 days), compared to no glycopyrrolate (21.6%; p = 0.0849; 2.7 days; p < 0.0001). POH was lower (18.1%) in 2015, than in 2012 (25.6%; p = 0.0007). POPA was lower with RTP in 2015 (0.6%), than in 2012 (4.8%; p = 0.0088). For the 2015 patients, LOS was lower with audit-documented RTP (2.2 days), compared to other patients (2.7 days; p = 0.0246). CONCLUSIONS: These findings are only hypothesis-generating. A randomized clinical trial is needed to confirm whether RTP has an inverse association with POH and POPA, and if RTP and glycopyrrolate are associated with improved outcomes.

ABSTRACT

BACKGROUND AND OBJECTIVES: No criteria define indications for laparoscopic splenectomy in trauma. This investigation compared characteristics of trauma patients and outcomes between laparoscopic and open splenectomies. METHODS: Patients were identified retrospectively by using ICD-9 codes. Included patients were 18 or older, with a blunt splenic injury from January 1, 2011, through December 31, 2014, and required splenectomy. Excluded patients had penetrating trauma, successful nonoperative management, or successful embolization. Variables included demographics, presenting characteristics, injury severity scores, abdominal abbreviated injury scores, splenic injury grade, surgical indication and approach (open or laparoscopic), surgery length, intra-operative blood loss, transfusions, length of stay, complications, mortality, and discharge disposition. RESULTS: Forty-one patients underwent open splenectomy, and 11 underwent laparoscopic splenectomy. The mean age was 48.7 years, and men comprised the sample majority (36/52). The groups were well matched for age, abdominal injury scores, and admission vital signs. The open group had a significantly lower level of consciousness and more acidosis compared with the laparoscopic group. Most laparoscopic splenectomies were performed after failed nonoperative management or embolization. The indications for open splenectomy were a positive focused assessment with sonography for trauma and computed tomography results. Laparoscopic patients had significantly longer times between presentation and surgery and longer operations, but had significantly less blood loss and fewer transfusions compared with the open group. There were no differences in mortality, length of stay, complications, or discharge dispositions. CONCLUSION: Laparoscopic splenectomy is useful in patients with blunt trauma in whom conservative management produced no improvement and who do not have other injuries to preclude laparoscopy.

ABSTRACT

The value of prehospital red blood cell (RBC) transfusion for trauma patients is controversial. The purposes of this literature review were to determine the mortality rate of trauma patients with hemodynamic instability and the benefit of prehospital RBC transfusion. A 30-year systematic literature review was performed in 2016. Eligible studies were combined for meta-analysis when tests for heterogeneity were insignificant. The synthesized mortality was 35.6% for systolic blood pressure ≤ 90 mmHg; 51.1% for ≤ 80 mmHg; and 63.9% for ≤ 70 mmHg. For patients with either hypotension or emergency trauma center transfused RBCs, the synthesized Injury Severity Score (ISS) was 27.0 and mortality was 36.2%; the ISS and mortality correlation was r = 0.766 (P = 0.0096). For civilian patients receiving prehospital RBC transfusions, the synthesized ISS was 27.5 and mortality was 39.5%. One civilian study suggested a decrement in mortality with prehospital RBC transfusion; however, patient recruitment was only one per center per year and mortality was < 10% despite an ISS of 37. The same study created a matched control subset and indicated that mortality decreased using multivariate analysis; however, neither the assessed factors nor raw mortality was presented. Civilian studies with patients undergoing prehospital RBC transfusion and a matched control subset showed that the synthesized mortality was similar for those transfused (37.5%) and not transfused (38.7%; P = 0.8933). A study of civilian helicopter patients demonstrated a similar 30-day mortality for those with and without prehospital blood product availability (22% versus 21%; P = 0.626). Mortality in a study of matched military patients was better for those receiving prehospital blood or plasma (8%) than the controls (20%; P = 0.013). However, transfused patients had a shorter prehospital time, more advanced airway procedures, and higher hospital RBC transfusion (P < 0.05). A subset with an ISS > 16 showed similar mortality with and without prehospital RBC availability (27.6% versus 32.0%; P = 0.343). Trauma patient mortality increases with the magnitude of hemodynamic instability and anatomic injury. Some literature evidence indicates no survival advantage with prehospital RBC availability. However, other data suggesting a potential benefit is confounded or likely to be biased.

ABSTRACT

We delineated the incidence of trauma patient pulmonary embolism (PE) and risk conditions by performing a systematic literature review of those at risk for deep vein thrombosis (DVT). The PE proportion was 1.4 per cent (95% confidence interval = 1.2-1.6) in at-risk patients. Of 10 conditions, PE was only associated with increased age (P < 0.01) or leg injury (P < 0.01; risk ratio = 1.6). As lower extremity DVT (LEDVT) proportions increased, mortality proportions (P = 0.02) and hospital stay (P = 0.0002) increased, but PE proportions did not (P = 0.13). LEDVT was lower with chemoprophylaxis (CP) (4.9%) than without CP (19.1%; P < 0.01). PE was lower with CP (1.0%) than without CP (2.2%; P = 0.0004). Mortality was lower with CP (6.6%) than without CP (11.6%; P = 0.002). PE was similar with (1.2%) and without (1.9%; P = 0.19) mechanical prophylaxis (MP). LEDVT was lower with MP (8.5%) than without MP (12.2%; P = 0.0005). PE proportions were similar with (1.3%) and without (1.5%; P = 0.24) LEDVT surveillance. Mortality was higher with LEDVT surveillance (7.9%) than without (4.8%; P < 0.01). A PE mortality of 19.7 per cent (95% confidence interval = 18-22) × a 1.4 per cent PE proportion yielded a 0.28 per cent lethal PE proportion. As PE proportions increased, mortality (P = 0.52) and hospital stay (P = 0.13) did not. Of 176 patients with PE, 76 per cent had no LEDVT. In trauma patients at risk for DVT, PE is infrequent, has a minimal impact on outcomes, and death is a black swan event. LEDVT surveillance did not improve outcomes. Because PE was not associated with LEDVT and most patients with PE had no LEDVT, preventing, diagnosing, and treating LEDVT may be ineffective PE prophylaxis.

ABSTRACT

BACKGROUND: Age-related brain atrophy has been represented by simple 1-dimensional (1-D) measurements on computed tomography (CT) for several decades and, more recently, with 3-dimensional (3-D) analysis, using brain volume (BV) and cerebrospinal fluid volume (CSFV). We aimed to show that simple 1-D measurements would be associated with 3-D values of age-related atrophy and that they would be related to post-traumatic intracranial hemorrhage (ICH). METHODS: Patients ≥60 years with head trauma were classified with central atrophy (lateral ventricular body width >30 mm) and/or cortical atrophy (sulcus width ≥2.5 mm). Composite atrophy was the presence of central or cortical atrophy. BV and CSFV were computed using a Siemens Syngo workstation (VE60A). RESULTS: Of 177 patients, traits were age 78.3 ± 10, ICH 32.2%, central atrophy 39.5%, cortical atrophy 31.1%, composite atrophy 49.2%, BV 1,156 ± 198 mL, and CSFV 102.5 ± 63 mL. CSFV was greater with central atrophy (134.4 mL), than without (81.7 mL, p < 0.001). BV was lower with cortical atrophy (1,034 mL), than without (1,211 mL; p < 0.001). BV was lower with composite atrophy (1,103 mL), than without (1,208 mL; p < 0.001). CSFV was greater with composite atrophy (129.1 mL), than without (76.8 mL, p < 0.001). CSFV÷BV was greater with composite atrophy (12.3%), than without (6.7%, p < 0.001). Age was greater with composite atrophy (80.4 years), than without (76.3, p = 0.006). Age had an inverse correlation with BV (p < 0.001) and a direct correlation with CSFV (p = 0.0002) and CSFV÷BV (p < 0.001). ICH was greater with composite atrophy (49.4%), than without (15.6%; p < 0.001; odds ratio = 5.3). BV was lower with ICH (1,089 mL), than without (1,188 mL; p = 0.002). CSFV÷BV was greater with ICH (11.1 %), than without (8.7%, p = 0.02). ICH was independently associated with central atrophy (p = 0.001) and cortical atrophy (p = 0.003). CONCLUSIONS: Simple 1-D measurements of age-related brain atrophy are associated with 3-D values. Clinical validity of these methods is also supported by their association with post-injury ICH. Intracranial 3-D software is not available on many CT scanners and can be cumbersome, when available. Simple 1-D measurements, using the study methodology, are a practical method to objectify the presence of age-related brain atrophy.

ABSTRACT

BACKGROUND: The impact of antithrombotic agents (warfarin, clopidogrel, ASA) on traumatic brain injury outcomes is highly controversial. Although cerebral atrophy is speculated as a risk for acute intracranial hemorrhage, there is no objective literature evidence. MATERIALS AND METHODS: This is a retrospective, consecutive investigation of patients with signs of external head trauma and age ≥60 years. Outcomes were correlated with antithrombotic-agent status, coagulation test results, admission neurologic function, and CT-based cerebral atrophy dimensions. RESULTS: Of 198 consecutive patients, 36% were antithrombotic-negative and 64% antithrombotic-positive. ASA patients had higher arachidonic acid inhibition (p = 0.04) and warfarin patients had higher INR (p<0.001), compared to antithrombotic-negative patients. Antithrombotic-positive intracranial hemorrhage rate (38.9%) was similar to the antithrombotic-negative rate (31.9%; p = 0.3285). Coagulopathy was not present on the ten standard coagulation, thromboelastography, and platelet mapping tests with intracranial hemorrhage and results were similar to those without hemorrhage (p≥0.1354). Hemorrhagic-neurologic complication (intracranial hemorrhage progression, need for craniotomy, neurologic deterioration, or death) rates were similar for antithrombotic-negative (6.9%) and antithrombotic-positive (8.7%; p = 0.6574) patients. The hemorrhagic-neurologic complication rate was increased when admission major neurologic dysfunction was present (63.2% versus 2.2%; RR = 28.3; p<0.001). Age correlated inversely with brain parenchymal width (p<0.001) and positively with lateral ventricular width (p = 0.047) and cortical atrophy (p<0.001). Intracranial hemorrhage correlated with cortical atrophy (p<0.001) and ventricular width (p<0.001). CONCLUSIONS: Intracranial hemorrhage is not associated with antithrombotic agent use. Intracranial hemorrhage patients have no demonstrable coagulopathy. The association of preinjury brain atrophy with acute intracranial hemorrhage is a novel finding. Contrary to antithrombotic agent status, admission neurologic abnormality is a predictor of adverse post-admission outcomes. Study findings indicate that effective hemostasis is maintained with antithrombotic therapy.
