| 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。

| Abstract: | 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. |
