What Happens After a Stop the Bleed Class? The Contrast Between Theory and Practice.

OBJECTIVE: The Department of Homeland Security launched the Stop the Bleed initiative, a campaign intended to teach bystanders hemorrhage control strategies. Despite the program's popularity, little is known about actions taken by participants afterwards. We sought to determine how often participants acquired the equipment that is necessary in applying the skills taught. DESIGN: A standardized survey instrument was distributed to all American College of Surgeons Bleeding Control Basic (B-Con) class participants from 05/2017 to 01/2018. The instrument queried about the likelihood of applying skills and obtaining materials. A web-based survey was administered one month later inquiring whether materials were obtained and barriers that would prohibit acquisition. SETTING: Academic, urban, Level I trauma center. PARTICIPANTS: Healthcare and nonhealthcare personnel. RESULTS: There were 336 and 183 participants who completed the initial and subsequent web-based survey, respectively. Participants indicated a high likelihood of applying a tourniquet (95.5%), applying pressure (97.9%), and packing a wound (96.4%), if required. Additionally, 74.7% and 76.2% reported a high likelihood of obtaining a tourniquet and packing material, respectively. However, only 21.3% and 50.8% obtained a tourniquet and packing material, respectively, 1 month later. Cost, time, and accessibility of items during a time of need were cited to be common reasons for not obtaining these materials. CONCLUSIONS: Despite reporting a high likelihood of utilizing hemorrhage control skills upon completion of the B-Con class, few went on to acquire the materials needed to apply these skills among those who responded. These results may be impacted by loss of follow up and response bias. Developing strategies that allow for easy access to materials is imperative and may lead to both better implementation of the purposes of the program and improved dissemination of its principles within the community.

CT Chest with IV Contrast Compared with CT Angiography after Blunt Trauma.

Blunt aortic injury (BAI) after chest trauma is a potentially lethal condition. Rapid diagnosis is important to appropriately treat patients. The purpose of this study was to compare CT with intravenous contrast (CTI) to CT with angiography (CTA) in the initial evaluation of blunt chest trauma patients. This was a retrospective review of all blunt trauma patients who received a CTI or CTA during the initial evaluation at an urban Level I trauma center from January 1, 2010 to December 31, 2013. Two-hundred and eighty-one trauma patients met inclusion criteria. Most, 167/281 (59%) received CTI and 114/281 (41%) received CTA. There were no differences between cohorts in age, gender, initial heart rate, systolic blood pressure, and Glasgow Coma Scale in emergency department. Mortality rates were similar for CTI and CTA (4% vs 8%, P = 0.20). CTI identified an injury in 54 per cent compared with 46 per cent in CTA (P = 0.05). Overall, 2 per cent of patients had BAI with similar rates in CTI and CTA (2% vs 2%, P = 0.80). BAI was not missed using either CTI or CTA. Trauma patients studied with CTI had similar diagnostic findings as CTA. CTI may be preferable to CTA during the initial assessment for possible BAI because of a single contrast injection for whole body CT.

Bicycle trauma and alcohol intoxication.

INTRODUCTION: As bicycling has become more popular, admissions after bicycle trauma are on the rise. The impact of alcohol use on bicycle trauma has not been well studied. The aim of this study was to examine the effect of alcohol intoxication on injury burden following bicycle-related crashes. METHODS: A retrospective review of trauma patients presenting to a Level I trauma center after bicycle-related crashes from January 2002 to December 2011 was conducted. Demographics, injury data, alcohol intoxication, helmet use, and clinical outcomes were reviewed. Blood alcohol level (BAL) was considered positive if >0.01 g/dL. Variables were compared between patients based on BAL: negative, 0.01-0.16 g/dL, and >0.16 g/dL. RESULTS: During the 10 year study period, 563 patients met study criteria; mean age was 33.5 ± 16.5 years, 87% were male, and mortality was 1%. On average, bicycle crashes increased over the study period by 4.4 collisions per year. BAL was tested in 211 (38%) patients. Mean BAL was 0.24 g/dL, with 37% of these patients being intoxicated (BAL ≥ 0.010 g/dL). Intoxicated patients were significantly less likely to wear a helmet (4.7% vs. 22.2%, p = 0.002) and to be involved in motor vehicle crash (59.0% vs. 81.2%, p < 0.001). There was no difference noted in the injury burden including ISS ≥ 16 (14.3% vs. 19.5%, p = 0.335) and AIS Head ≥ 3 (17.9% vs. 21.8%, p = 0.502). When comparing patients according to their BAL, there was a decreasing risk of motor vehicle collision with increasing BAL (81.2% for undetected, 76.5% for BAL ≤ 0.16 g/dL and 54.1% for BAL >0.16 g/dL, p < 0.001). The risk for a severe head injury (AIS Head ≥ 3) was significantly lower in helmeted patients (8.4% vs. 15.8%, p = 0.035). CONCLUSIONS: The incidence of bicycle-related crashes is increasing and more than a third of patients tested for alcohol after bicycle-related crashes are found to be intoxicated. The injury burden in intoxicated patients, including head trauma, was not different compared to non-intoxicated patients. In addition, the risk for a collision with a motor vehicle was significantly lower. Nonetheless, these patients rarely utilize a helmet. The findings from this study can be used for the development and implementation of preventive strategies to minimize the injury burden associated with bicycle crashes and intoxicated cyclists.

CT Chest with IV Contrast Compared with CT Angiography after Blunt Trauma.

Blunt aortic injury (BAI) after chest trauma is a potentially lethal condition that requires rapid diagnosis for appropriate treatment. We compared CT with IV contrast (CTI) with CT with angiography (CTA) during the initial phase of care at an urban Level I trauma center from January 1, 2010 to December 31, 2013. Overall, 281 patients met inclusion criteria with 167 (59%) CTI and 114 (41%) CTA. There were no differences between cohorts in age, gender, initial heart rate, systolic blood pressure, and Glasgow Coma Scale. Mortality rates were similar for CTI and CTA (4% vs 8%, P = 0.20). CTI identified any chest injury in 54 per cent of patients compared with 46 per cent with CTA (P = 0.05). The rate of BAI was similar with CTI and CTA (2% vs 2%, P = 0.80), and neither modality was falsely negative. We conclude that CTI and CTA are similar at evaluating trauma patients for BAI, although CTI may be preferable during the initial assessment phase because the contrast injection may be combined with abdominal scanning and image time is reduced when whole-body CT is required.

A promising new alternative for the rapid reversal of warfarin coagulopathy in traumatic intracranial hemorrhage.

BACKGROUND: Internationally, Factor IX complex (FIX complex) has been used to correct warfarin-induced coagulopathy. We present our experience with 28 patients using FIX complex. METHODS: A retrospective chart review was conducted between November 2002 and July 2006 on patients with warfarin-induced coagulopathy. We recorded the dose and timing of FIX complex, serial international normalized ratios (INRs), early adverse events, and patient outcome. RESULTS: Twenty-eight patients met criteria. The mean INR on admission was 5.1, and after FIX complex infusion was reduced significantly to 1.9 (P = .008). Eleven patients had a repeat INR drawn within 30 minutes after FIX complex infusion. The mean time to correction was 13.5 minutes. There were no early thrombotic events or allergic reactions. CONCLUSIONS: FIX complex results in an immediate reversal of coagulopathy within 15 minutes after administration. Its use should be considered as an alternative treatment to fresh-frozen plasma and recombinant Factor VIIa. Prospective randomized trials are needed to confirm these findings.
