低强度超声波对开放性创口的冲洗效果

背景：虽然医疗技术不断进步，但开放性损伤导致的伤口感染率仍然较高。 目的：对比低强度超声波与传统方法对开放性创伤伤口冲洗的效果。 方法：收集84例开放性创伤患者，观察经低强度超声波冲洗的42例患者(观察组)的伤口细菌清除及愈合情况，并与经常规冲洗的42例患者(对照组)细菌清除及愈合情况。 结果与结论：观察组清创2 h后伤口组织中细菌清除率、伤口甲级愈合率明显高于对照组(P < 0.01，P < 0.05)；观察组5 d伤口愈合面积明显大于对照组，其平均愈合时间较对照组有明显缩短(P < 0.01)。说明使用低强度超声波创伤冲洗机对伤口进行冲洗，具有清除效果确切和操作简便易行，同时能促进伤口愈合。

Effect of low-intensity ultrasound on washing open injury

BACKGROUND: Infection rate of open injury is high. OBJECTIVE: To compare the effects of low-intensity ultrasound and traditional method on washing open wounds. METHODS: Clinical data of 84 patients with open wounds were collected. Bacterial eradication and wound healing of 42 patients irrigated by low-intensity ultrasound were observed and compared with 42 patients (control group) undergoing regular flushing. RESULTS AND CONCLUSION: The wound tissue bacterial clearance rate and A level union rate at 2 hours after debridement were significantly greater in observation group compared with control group (P < 0.01, P < 0.05). The area of wound healing at 5 days was greater in observation group compared with control group, and the average healing time was significantly shortened than the control group (P < 0.01). Results shown that low-intensity ultrasound wound washing machine can effectively wash the wound with simple operation and promote wound healing.
