Abstract:

Introduction: Graduate medical education (GME) lacks a standardized military training program for general surgery residents, and concern exists that they may not be prepared to serve as combat surgeons on training completion. The purpose of this study was to assess military surgery trainee satisfaction with their programs. Our hypothesis was that military residents were not completely confident to care for combat casualties on completion of current GME training.

Methods: We surveyed US Army, Navy, and Air Force general surgery residents and fellows between November 2023 and March 2024 to assess their confidence in managing combat injuries. Queried residents further rate their overall satisfaction with surgical training, perceived level of deployment preparedness and curriculum elements which they thought would be most beneficial to their training.

Results: The survey yielded an overall 43% response rate (132/305) with a response rate of 42% (61/147) from the Army, 56% (44/79) from the Navy, and 34% (27/79) from the Air Force. Most trainees were trained in military medical treatment facility residency programs (n=91, 68.9%) and nearly half of respondents (n=64, 49%) were senior trainees (postgraduate year (PGY)4, PGY5, and fellows). Among all trainees, only two-thirds (n=88, 67%,) thought they were adequately prepared to deploy and operate on military combat casualties by the end of residency but 114 (86%) were satisfied with the training they received during general surgery residency in adult trauma, 103 (78%) in critical care, and 112 (85%) in acute care surgery. However, more than half were unsatisfied with the training they received in obstetric/gynecologic and urologic emergencies (n=72, 55%; and n=67, 51%, respectively).

Conclusion: Although the majority of military surgical residents surveyed are satisfied with their training in adult trauma, critical care, and emergency general surgery, a large number of trainees thought they would not be ready to deploy and manage combat casualties.

Level of evidence: Prognostic and epidemiological, Level IV.

With the increasing age of the population in the USA, fall prevention events to target older patients are imperative. The American Association for the Surgery of Trauma hosted a fall prevention event at the host city of the 2023 Annual Meeting. We review the planning and implementation of this "Stop the Falls" event, in hopes that other institutions may benefit and sustainably effectuate fall prevention events for an increasingly geriatric population.

Background: Prior studies have associated nighttime transfer of patients from the intensive care unit (ICU) with increased morbidity. This study sought to examine this relationship in traumatically injured patients, as this has not been previously performed.

Methods: A retrospective review of traumatically injured patients admitted to a Level I Trauma Center's ICU from January 2021 to September 2022 was performed. "Day shift" (DS) was defined as 07:00 to 19:00 and "night shift" (NS) as 19:01 to 06:59. The time of transfer completion was based on the time of the patient arrival at the destination unit. The univariate analysis compared patients with completed transfers during DS and NS. Multivariate logistic regression was performed to predict readmission to the ICU.

Results: A total of 1,800 patients were included in the analysis, with 608 patients that had completed transfers during NS, and 1,192 during DS. Both groups were similar, with no significant differences in age, sex, Injury Severity Score (ISS), mechanism of injury, or median total comorbidities. The NS group had a longer median time to transfer completion (10.1 (IQR 5.5-13.6) hours vs 5.1 (IQR 2.9-8.4) hours; p<0.001). A significantly higher proportion of the NS group had a readmission to the ICU (60 (10.0%) vs 86 (7.0%); p=0.03) or a major complication (72 (11.9%) vs 107 (9.0%); p=0.048). When controlling for age, comorbidities, ISS, time to bed assignment and to transfer completed, and ICU length of stay, transfer completion during NS was associated with 1.56 times higher odds of having an ICU readmission (OR 1.56 (95% CI 1.05, 2.33); p=0.03).

Conclusions: Trauma patients transferred from the ICU during NS experienced longer delays, readmission to the ICU, and major complications significantly more often. With increasing hospital bed shortages, patient transfers must be analyzed to minimize worsened outcomes, especially in traumatically injured patients.

Level of evidence: Level III, therapeutic/care management.

Background: Retrohepatic inferior vena cava (IVC) injuries remain among the most lethal and serious liver injuries. Gauze packing is currently the first choice for IVC injuries; however, laparotomy itself poses the risk of circulatory collapse. Thus, less invasive treatment strategies are needed.

Methods: In this study, we conducted an animal experiment to replicate and validate successful treatments for an actual case of retrohepatic IVC injury that we had encountered.

Results: A woman in her 80s presented to our hospital due to cardiac arrest caused by a pulmonary artery embolism. Venoarterial extracorporeal membrane oxygenation (ECMO) was introduced, and the patient was resuscitated. After resuscitation, contrast-enhanced CT revealed liver and retrohepatic IVC injuries, possibly caused by chest compressions. Liver injury was treated using transarterial embolization of the left hepatic artery. To treat the retrohepatic IVC injury, ECMO flow was increased to enhance the negative drainage pressure. The extravasation of the contrast medium had resolved in IVC angiography, and we opted for nonoperative management. The patient's hemodynamic status gradually stabilized, and ECMO was withdrawn on day 6. We confirmed these findings in a dog model of retrohepatic IVC injury.

Conclusions: Our findings from the patient and the animal model suggest that the flow diversion effect of ECMO can effectively manage active bleeding from the IVC by inserting a drainage cannula across the injured lesion. We think this procedure represents a novel treatment option for retrohepatic IVC injuries.
