Changes in trends during the COVID-19 lockdown: An urban, Level-1 trauma center's experience.

BACKGROUND: A community lockdown has a profound impact on its citizens. Our objective was to identify changes in trauma patient demographics, volume, and pattern of injury following the COVID-19 lockdown. METHODS: A retrospective review was conducted at a Level-1 Trauma Center from 2017 to 2020. RESULTS: A downward trend in volume is seen December-April in 2020 (R2 = 0.9907). February through April showed an upward trend in 2018 and 2019 (R2= 0.80 and R2 = 0.90 respectively), but a downward trend in 2020 (R2 = 0.97). In April 2020, there was 41.6% decrease in total volume, a 47.4% decrease in blunt injury and no decrease in penetrating injury. In contrast to previous months, in April the majority of injuries occurred in home zip codes. CONCLUSIONS: A community lockdown decreased the number of blunt trauma, however despite social distancing, did not decrease penetrating injury. Injuries were more likely to occur in home zip codes.

Does Pain Have a Role When It Comes to Tourniquet Training?

BACKGROUND: One of the greatest conundrums with tourniquet (TQ) education is the use of an appropriate surrogate of hemorrhage in the training setting to determine whether a TQ has been successfully used. At our facility, we currently use loss of audible Doppler signal or loss of palpable pulse to represent adequate occlusion of vasculature and thus successful TQ application. We set out to determine whether pain can be used to indicate successful TQ application in the training setting. METHODS: Three tourniquet systems (a pneumatic tourniquet, Combat Application Tourniquet® [C-A-T], and Stretch Wrap and Tuck Tourniquet™ [SWAT-T]) were used to occlude the arterial vasculature of the left upper arm (LUA), right upper arm (RUA), left forearm (LFA), right forearm (RFA), right thigh (RTH), and right calf (RCA) of 41 volunteers. A 4MHz, handheld Doppler ultrasound was used to confirm loss of Doppler signal (LOS) at the radial or posterior tibial artery to denote successful TQ application. Once successful placement of the TQ was noted, subjects rated their pain from 0 to 10 on the visual analog scale. In addition, the circumference of each limb, the pressure with the pneumatic TQ, number of twists with the C-A-T, and length of TQ used for the SWAT-T to obtain LOS was recorded. RESULTS: All 41 subjects had measurements at all anatomic sites with the pneumatic TQ, except one participant who was unable to complete the LUA. In total, pain was rated as 1 or less by 61% of subjects for LUA, 50% for LFA, 57.5% for RUA, 52.5% RFA, 15% for RTH, and 25% for RCA. Pain was rated 3 or 4 by 45% of subjects for RTH. For the C-A-T, data were collected from 40 participants. In total, pain was rated as 1 or less by 57.5% for the LUA, 70% for the LFA, 62.5% for the RUA, 75% for the RFA, 15% for the RTH, and 40% for the RCA. Pain was rated 3 or 4 by 42.5%. The SWAT-T group consisted of 37 participants for all anatomic locations. In total, pain was rated as 1 or less by 27% for LUA, 40.5% for the LFA, 27.0% for the RUA, 43.2 for the RFA, 18.9% for the RTH, and 16.2% for the RCA. Pain was rated 5 by 21.6% for RTH application, and 3 or 4 by 35%. CONCLUSION: The unexpected low pain values recorded when loss of signal was reached make the use of pain too sensitive as an indicator to confirm adequate occlusion of vasculature and, thus, successful TQ application.

Management of adult pancreatic injuries: A practice management guideline from the Eastern Association for the Surgery of Trauma.

BACKGROUND: Traumatic injury to the pancreas is rare but is associated with significant morbidity and mortality, including fistula, sepsis, and death. There are currently no practice management guidelines for the medical and surgical management of traumatic pancreatic injuries. The overall objective of this article is to provide evidence-based recommendations for the physician who is presented with traumatic injury to the pancreas. METHODS: The MEDLINE database using PubMed was searched to identify English language articles published from January 1965 to December 2014 regarding adult patients with pancreatic injuries. A systematic review of the literature was performed, and the Grading of Recommendations Assessment, Development and Evaluation framework was used to formulate evidence-based recommendations. RESULTS: Three hundred nineteen articles were identified. Of these, 52 articles underwent full text review, and 37 were selected for guideline construction. CONCLUSION: Patients with grade I/II injuries tend to have fewer complications; for these, we conditionally recommend nonoperative or nonresectional management. For grade III/IV injuries identified on computed tomography or at operation, we conditionally recommend pancreatic resection. We conditionally recommend against the routine use of octreotide for postoperative pancreatic fistula prophylaxis. No recommendations could be made regarding the following two topics: optimal surgical management of grade V injuries, and the need for routine splenectomy with distal pancreatectomy. LEVEL OF EVIDENCE: Systematic review, level III.

Outcomes in traumatic brain injury for patients presenting on antiplatelet therapy.

An increasing number of patients are presenting to trauma units with head injuries on antiplatelet therapy (APT). The influence of APT on these patients is poorly defined. This study examines the outcomes of patients on APT presenting to the hospital with blunt head trauma (BHT). Registries of two Level I trauma centers were reviewed for patients older than 40 years of age from January 2008 to December 2011 with BHT. Patients on APT were compared with control subjects. Primary outcome measures were in-hospital mortality, intracranial hemorrhage (ICH), and need for neurosurgical intervention (NI). Hospital length of stay (LOS) was a secondary outcome measure. Multivariate analysis was used and adjusted models included antiplatelet status, age, Injury Severity Score (ISS), and Glasgow coma scale (GCS). Patients meeting inclusion criteria and having complete data (n = 1547) were included in the analysis; 422 (27%) patients were taking APT. Rates of ICH, NI, and in-hospital mortality of patients with BHT in our study were 45.4, 3.1, and 5.8 per cent, respectively. Controlling for age, ISS, and GCS, there was no significant difference in ICH (odds ratio [OR], 0.84; 95% confidence interval [CI], 0.61 to 1.16), NI (OR, 1.26; 95% CI, 0.60 to 2.67), or mortality (OR, 1.79; 95% CI, 0.89 to 3.59) associated with APT. Subgroup analysis revealed that patients with ISS 20 or greater on APT had increased in-hospital mortality (OR, 2.34; 95% CI, 1.03 to 5.31). LOS greater than 14 days was more likely in the APT group than those in the non-APT group (OR, 1.85; 95% CI, 1.09 to 3.12). The effects of antiplatelet therapy in patients with BHT aged 40 years and older showed no difference in ICH, NI, and in-hospital mortality.
