Randomized Controlled TrialImpact of low-dose vasopressin on trauma outcome: prospective randomized study.
We previously found that regardless of the animal injury model used resuscitation strategies that minimize fluid administration requirements lead to better outcomes. We hypothesized that a resuscitation regimen that limited the total volume of fluid administered would reduce morbidity and mortality rates in critically ill trauma patients. ⋯ This is the first trial to investigate the impact of vasopressin administration in trauma patients. Infusion of low-dose vasopressin maintained elevated serum vasopressin levels and decreased fluid requirements after injury.

Randomized Controlled TrialProspective randomized controlled trial to analyze the effects of intermittent pneumatic compression on edema following autologous femoropopliteal bypass surgery.
Patients who undergo autologous femoropopliteal bypass surgery develop postoperative edema in the revascularized leg. The effects of intermittent pneumatic compression (IPC) to treat and to prevent postreconstructive edema were examined in this study. ⋯ Edema following femoropopliteal bypass surgery occurs in all patients. For the prevention and treatment of that edema the use of a class I CS proved superior to treatment with IPC. The use of CS remains the recommended practice following femoropopliteal bypass surgery.

Randomized Controlled Trial Comparative StudyEffects of virtual reality simulator training method and observational learning on surgical performance.
Virtual reality (VR) simulators and Web-based instructional videos are valuable supplemental training resources in surgical programs, but it is unclear how to optimally integrate them into minimally invasive surgical training. ⋯ Proctored VR training is no more effective than independent training with respect to surgical performance. Therefore, time-consuming human expert feedback during VR training may be unnecessary. Instructional videos, while useful, may not be adequate substitutes for actual observation when trainees are learning minimally invasive surgical procedures.
