Comparative Study
Sixty-five clinical cases of free tissue transfer using long arteriovenous fistulas or vein grafts.
Traumatic limb injuries requiring free tissue transfer for coverage, often lack healthy recipient vessels adjacent to the defect. In these patients, vein grafts are required to bridge the gap of either the artery, vein or both. For the latter situation, a temporary arteriovenous fistula (AVF) can be created and allowed to mature and then divided and used as recipient artery and veins for the free flap. ⋯ Although a longer graft length seemed to be associated with a higher re-exploration rate, there was no statistical significance. One-stage AVFs can be used with good results, however, two-stage AVFs are associated with a high graft occlusion rate, wound failure rate and limb amputation rate. In all cases, a large caliber graft such as the great saphenous vein provided a large (relatively low resistance) conduit for bridging the defect.

The use of quantitative cultures of the bronchoalveolar lavage (BAL) effluent to distinguish between posttraumatic inflammatory response and ventilator-associated pneumonia (VAP) is becoming more common. However, the diagnostic threshold of either 10 or 10 colonies/mL remains debatable. Because mortality from VAP is related to treatment delay, some have chosen a lower diagnostic threshold (>10 colonies/mL). This may result in unnecessary antibiotic use with its sequelae: increased resistant organisms, antibiotic-related complications, and increased costs. The purpose of this study is to determine the optimal diagnostic threshold for VAP diagnosis using quantitative cultures of the BAL effluent. ⋯ The VAP diagnostic threshold for quantitative BAL in trauma patients should be >10 colonies/mL. One may consider a threshold of >10 colonies/mL in severely injured patients with Pseudomonas or Acinetobacter species.

The purpose of this report is to identify the most important research questions pertaining to the acute care of the injured patient using a Web-based Delphi technique to achieve expert opinion consensus. ⋯ This report identifies the areas of trauma care in which research efforts might best be directed. Fully 40% of the key research questions could be considered to fall under the interest and auspices of the CDC-NCIPC. The remaining questions cover a broad range of topics and likely funding sources, emphasizing the need for a coordinated oversight of research funding in trauma care.

Early airway management is advocated for patients with penetrating neck trauma who have any signs of airway compromise. This study examined the clinical course of patients with penetrating neck trauma who received prehospital blind nasotracheal intubation, including successful intubation rates, and outcomes. ⋯ The patients managed with blind nasotracheal intubation did not experience complications related to the choice of airway management. Despite prior warnings in the literature, the results of this study suggest that blind nasotracheal intubation may well be a valuable tool for the management of patients with penetrating neck trauma.

The purpose of this study was to examine whether microwave tissue coagulation (MTC) therapy is capable of stopping bleeding from severe liver injury in pigs. ⋯ MTC therapy was thus found to provide simple, rapid, and definitive hemorrhage control in cases of severe liver injury without the need for reoperation.
