In previous studies, mild hypothermia (34 degrees C) during uncontrolled hemorrhagic shock (HS) increased survival. Hypothermia also increased mean arterial pressure (MAP), which may have contributed to its beneficial effect. We hypothesized that hypothermia would improve survival in a pressure-controlled HS model and that prolonged hypothermia would further improve survival. ⋯ Brief hypothermia had physiologic benefit and a trend toward improved survival. Prolonged mild hypothermia significantly increased survival after severe HS even with controlled MAP. Extending the duration of hypothermia beyond the acute phases of shock and resuscitation may be needed to ensure improved outcome after prolonged HS.

Published contraindications to nonoperative management (NOM) of blunt splenic injury (BSI) include age > or = 55, Glasgow Coma Scale score < or = 13, admission blood pressure < 100 mm Hg, major (grades 3-5) injuries, and large amounts of hemoperitoneum. Recently reported NOM rates approximate 60%, with failure rates of 10% to 15%. This study evaluated our failures of NOM for BSI relative to these clinical factors. ⋯ Inclusion of all high-risk patients increased the NOM rate while maintaining a low failure rate. Although age > or = 55 and major BSI were independently associated with failure of NOM, approximately 80% of these high-risk patients were successfully managed nonoperatively. There was no increased mortality associated with failure. Although these factors may indeed predict failure, they do not necessarily contraindicate NOM.

A new technique to resurface wounds with composite biocompatible epidermal graft and artificial skin.
The incorporation of cultured epidermal autograft on the neodermis of artificial skin (Integra, Integra LifeSciences, Plainsboro, NJ) has been met with some difficulties. A new engraftment technique to resurface the wounds with Integra and composite biocompatible epidermal graft (CBEG) has been successfully applied on three patients for elective reconstructive procedures. ⋯ This engraftment technique has several advantages. The CBEG is much easier to handle than the conventional cultured epidermal autograft. It eliminates the invasive second procedure for skin harvesting, with resulting pain and scarring. The application of the CBEG can be easily performed at the bedside.

This article presents a retrospective analysis of a case series of diaphyseal forearm fractures in children treated with intramedullary Kirschner wires (K-wires). ⋯ This surgical technique is convenient, effective, and safe for treating displaced diaphyseal forearm fractures in children.
