Quantifying the Volume of Fluid Resuscitation Required to Normalize Lactate in Septic Patients
Characterizing the delays in adequate thromboprophylaxis after TBI
Background We sought to compare enoxaparin dosing for venous thromboembolism (VTE) prophylaxis in trauma patients with and without traumatic brain injury (TBI) to better understand the time and dose required to reach target anti-Xa levels. Our hypothesis was that patients with TBI have significant delays in the initiation of adequate pharmacological prophylaxis and require a higher enoxaparin dose than currently recommended.Methods The medical records of trauma patients who received enoxaparin dosing based on anti-Xa trough levels between August 2014 and October 2016 were reviewed. Patients were included if their anti-Xa trough level reached the target range (0.1 IU/mL to 0.2 IU/mL).Results A total of 163 patients had anti-Xa levels within the target range of which 41 (25.2%) had TBI. Patients with TBI had longer delays before initiating enoxaparin (7.5 days vs. 1.5 days after admission, p<0.01) and were more likely to receive unfractionated heparin prior to enoxaparin (46.3% vs. 11.5%, p<0.01). Anti-Xa levels reached the target range later in patients with TBI (11 days vs. 5 days after admission, p<0.01). Enoxaparin 40 mg two times per day was the median dose required to reach the target anti-Xa levels for both cohorts. VTE rates were higher among patients with TBI (22.0% vs. 9.0%, p=0.03). Four patients (9.8%) had progression of their intracranial hemorrhage prior to receiving enoxaparin, although none progressed during enoxaparin administration.Conclusion Among patients with TBI who reached target anti-Xa levels, 11 days after admission were required to reach a median enoxaparin dose of 40 mg two times per day. Unfractionated heparin was used as pharmacological prophylaxis in about half of these patients. The delay in reaching the target anti-Xa levels and the use of unfractionated heparin likely contribute to the higher VTE rate in patients with TBI.Level of evidence Level III, therapeutic
Penetrating Pharyngoesophageal Injury: Practice Patterns in the Era of Nonoperative Management – A National Trauma Data Bank Review from 2007 to 2011
Introduction: Selective nonoperative management of neck injuries from penetrating mechanism has become an acceptable management strategy. We herein characterize current management strategies of cervical pharyngoesophageal injuries implemented by trauma surgeons in the United States. Methods: The National Trauma Data Bank datasets 2007–2011 were queried for penetrating pharyngeal and/or cervical esophageal injuries. Subjects surviving 24 hours or more were analyzed based on whether a surgical exploration was pursued and by gunshot versus stabbing mechanism. Results: In all, 1,256 patients were identified, representing 6% of all penetrating neck injuries during the study period. The majority (84%) were male, with a median age of 27 years. Injury severity was high (median score of 14). Compared to stabbing victims, gunshot patients were more likely to have associated cervical spine (24% vs. 1%, p < .01) and carotid artery injury (14% vs. 9%, p < .01). Neck exploration was performed in 49% of patients who survived at least 24 hours, with 90% occurring within the first day of admission. Of patients who underwent a delayed neck exploration, 35% required a tracheostomy and 41% required a feeding tube placement. The overall mortality was 4%. Nonoperative management was not associated with increased odds for death (adjusted odds ratio (AOR) 0.55, p = .17). Conclusions: Nonoperative management of penetrating pharyngoesophageal injuries is commonly utilized with no effect on mortality
Is MRI Becoming the New CT for Cervical Spine Clearance? Trends in MRI Use at a Level I Trauma Center
Poor Corticospinal Motor Neuron Health Is Associated with Increased Symptom Severity in the Acute Phase Following Repetitive Mild TBI and Predicts Early ALS Onset in Genetically Predisposed Rodents
Traumatic brain injury (TBI) is a well-established risk factor for several neurodegenerative disorders including Alzheimer’s disease and Parkinson’s disease, however, a link between TBI and amyotrophic lateral sclerosis (ALS) has not been clearly elucidated. Using the SOD1G93A rat model known to recapitulate the human ALS condition, we found that exposure to mild, repetitive TBI lead ALS rats to experience earlier disease onset and shortened survival relative to their sham counterparts. Importantly, increased severity of early injury symptoms prior to the onset of ALS disease symptoms was linked to poor health of corticospinal motor neurons and predicted worsened outcome later in life. Whereas ALS rats with only mild behavioral injury deficits exhibited no observable changes in corticospinal motor neuron health and did not present with early onset or shortened survival, those with more severe injury-related deficits exhibited alterations in corticospinal motor neuron health and presented with significantly earlier onset and shortened lifespan. While these studies do not imply that TBI causes ALS, we provide experimental evidence that head injury is a risk factor for earlier disease onset in a genetically predisposed ALS population and is associated with poor health of corticospinal motor neurons
Electric Scooter Injury in Southern California Trauma Centers.
BACKGROUND: Electric scooters are popular in Southern California due to their ease of use, affordability, and availability. The objective of this study was to characterize how hospital admissions and outcomes varied due to electric scooter injury among Southern California trauma centers.
STUDY DESIGN: Trauma registry data from 9 urban trauma centers were queried for patients sustaining injury while operating an electric scooter from January to December 2018. Data collection included patient demographics, diagnoses, interventions, and outcomes.
RESULTS: During the 1-year study period, 87 patients required trauma surgeon care due to scooter-related injury, with a mean age of 35.1 years; 71.3% were male with 20.7% and 17.2% of patients requiring ICU admission and a surgical intervention, respectively. One (1.1%) patient died. The head and face were most commonly injured, followed by the extremities. Helmet use was uncommon (71.3%). High variability in patient volume was noted, with 2 centers considered high-incidence and the remaining low-incidence.
CONCLUSIONS: Injuries from electric scooter crashes are primarily to the head, face, and extremities, with approximately 1 in 5 patients requiring ICU admission and/or a surgical intervention. There is significant variation in patient volume among Southern California trauma centers that could affect the delivery of care with the abrupt introduction of this technology. Targeted public health interventions and policies might better address community use of the electric scooter

Developing and leading a sustainable organization for early career acute care surgeons: Lessons from the inaugural American Association for the Surgery of Trauma Associate Member Council
The associate membership of the American Association for the Surgery of Trauma (AAST) was established in 2019 to create a defined but incorporated entity within the larger AAST for the next generation of acute care surgeons. The Associate Member Council (AMC) was subsequently established in 2020 to provide the new AM with an elected group of leaders who would represent them within the AAST. In its inaugural year, this cohort of junior faculty and surgical trainees had developed for the AM a set of bylaws, a mission statement, a strategic vision, and a succession plan. The experience of the AAST AMC is exemplary of what can be accomplished with collaboration, mentorship, innovation, and tenacity. It has the potential to serve as a template for the creation and vitalization of future professional groups. In this piece, the AMC proposes a blueprint for the successful conception of a new organization
