Traumatic brain injury (TBI) and hemorrhagic shock (HS) are the leading causes of trauma-related deaths. These insults disrupt coagulation and endothelial systems. This study investigated whether previously reported differences in lesion size and brain swelling during normal saline (NS), colloids (Hextend [HEX]), and fresh frozen plasma (FFP) resuscitation are associated with differential effects on coagulation and endothelial systems. ⋯ In this clinically realistic large animal model of TBI + HS, NS resuscitation was associated with an early activation of coagulation, natural anticoagulation, and endothelial systems, compared with HEX and FFP.

Both intra- and perioperative care are essential for patients' safety. Training for intraoperative technical skills on simulators and for perioperative care in virtual patients have independently demonstrated educational value, but no training combining these 2 approaches has been designed yet. The aim of this study was to design a pathway approach for training in general surgery. A common disease requiring essential skills was chosen, namely, acute appendicitis. ⋯ A virtual care pathway approach has been designed for acute appendicitis, enabling trainees to follow simulated patients from admission to discharge.

Randomized Controlled Trial
Introduction of a comprehensive training curriculum in laparoscopic surgery for medical students: a randomized trial.
First- and second-year medical students have limited exposure to basic surgical skills. An introductory, comprehensive, simulation-based curriculum in basic laparoscopic skills may improve medical students' knowledge and technical and nontechnical skills and may raise their interest in a career in surgery. The purpose of this study was to (1) design a comprehensive, simulation-based training curriculum (STC) aimed to introduce junior medical students to basic laparoscopic skills and (2) compare structured and supervised learning and practice to a self-directed approach. ⋯ Participation in the STC resulted in significant gains in knowledge, technical skill, and attitudes toward nontechnical skills. Exposure of junior medical students to this curriculum before their clinical rotations is expected to enhance learning, maintain motivation, and increase interest in surgery as a future career.

Rapid thrombelastography (rTEG) has been advocated as a point-of-care test to manage trauma-induced coagulopathy. rTEG activated clotting time (T-ACT) results become available much sooner than other rTEG values, thus offering an attractive tool to guide blood component transfusion in a hemorrhagic shock. We hypothesize that patients with a prolonged T-ACT require replacement of platelets (Plts) and cryoprecipitate (Cryo) in addition to plasma to correct trauma-induced coagulopathy. ⋯ Injured patients requiring resuscitation with blood transfusion that have a T-ACT >140 seconds are polycoagulopathic and may benefit from early Cryo and Plts.

With the increasing aging population, the number of very elderly patients (age ≥80 years) undergoing emergency operations is increasing. Evaluating patient-specific risk factors for postoperative morbidity and mortality in the acute care surgery setting is crucial to improving outcomes. We hypothesize that sarcopenia, a severe depletion of skeletal muscles, is a predictor of morbidity and mortality in very elderly patients undergoing emergency surgery. ⋯ Sarcopenia was independently predictive of greater complication rates, discharge disposition, and in-hospital mortality in the very elderly emergency surgery population. Using sarcopenia as an objective tool to identify high-risk patients would be beneficial in developing tailored preventative strategies and potentially resource allocation in the future.
