摘要
目的 监测胸肩峰皮瓣微循环血流动态变化及其规律 ,为选择最佳断蒂时间提供可靠客观量化指标。 方法 应用激光多普勒血流计 (LDF)对 12例胸肩峰皮瓣转移面中点于术后 2～ 7天逐日进行微循环监测 ,皮瓣移植后第 4天起记录皮瓣蒂部阻断前、后LDF的PU(灌注单位 )值变化情况。 结果 胸肩峰皮瓣微循环血流变化可分为 2期 ,即术后前 4天的骤升期PU值分别为 3 5±1 3、4 5± 1 7、6 7± 2 9;术后 4～ 7天的平台期PU值分别为 7 4± 2 0、7 6± 2 3、7 3± 1 6。本组断蒂时间为术后 6～ 8天。 结论 胸肩峰皮瓣在转移修复面部缺损时 ,其微循环血流变化在平台期后期时 ,当阻断皮瓣蒂部后其PU值恢复到或超过阻断前水平的 5 0 %时进行断蒂 ,皮瓣全部成活。
Objective To monitor the microcirculation of thoraco acromial flaps. Methods The microcirculation in 12 thoraco acromial flaps was monitored continuously by laser Doppler flowmetry (LDF). Results The microcirculatory changes in thoraco acromial flaps were divided into two phases: rapid rising (2～4 days after operation) and plateaurising (4～7 days after operation). PU values were 7 4±2 0, 7 6±2 3 and 7 3±1 6 Conclusions In division of the thoraco acromial flaps within the plateau, the value (PU) returned to or exceeded 50% of that before application of the tourniquet. All flaps survived. The time of division was decreased to 6～8 after operation days.
