Comparative Study
Below-knee amputations as a result of land-mine injuries: comparison of primary closure versus delayed primary closure.
Antipersonnel land mines are designed to maim by mutilating the lower extremities, and these injuries are at higher risk for infection than injuries from other weapon systems. ⋯ Our results reveal that primary closure may be done in traumatic below-knee amputations caused by land-mine injuries with an acceptable infection rate, if the evacuation time is less than 6 hours, and if there is meticulous debridement.

A reliable means of assessing physician competency in performing ultrasound (US) is critical for training and credentialing. Objective Structured Clinical Examinations (OSCE) have been used successfully to assess clinical competency in other areas of surgical education but have not been applied previously to trauma ultrasound training. The objectives of this study were to assess physician performance in the focused abdominal sonography in trauma (FAST) examination by using a specifically designed OSCE, and to determine whether the OSCE detects differences in two determinants of competency (knowledge acquisition and clinical interpretation skills). ⋯ Knowledge acquisition and US interpretation skills can be assessed reliably with a specifically designed OSCE. Although both skills improved after participation in a FAST course, US interpretation scores were consistently lower than those for factual knowledge. This study supports the use of the objective structured clinical examination in both the design of ultrasound teaching programs and the assessment of physician competency.

Randomized Controlled Trial Clinical Trial
Low-dose vasopressin in the treatment of vasodilatory septic shock.
Despite appropriate therapy, refractory hypotension often occurs in septic shock. A double-blinded placebo controlled clinical trial was performed to assess the role of low-dose vasopressin (VP) as a pressor agent in septic shock. ⋯ A VP infusion improved arterial pressure and permitted the withdrawal of catecholamine vasopressors. VP is a useful agent in the treatment of refractory septic shock.
