威伐光治疗腹部手术伤口 手术后伤口局部照射,可提高局部组织的氧分压,组织灌注,为组织局部提供充足的能量和氧气; 增强局部组织温度,而皮肤表面温度没有变化; 有效的减少伤口渗出,减少伤口炎症反应,降低伤口感染风险; 激活免疫机制; 有效减轻伤口疼痛,减少止痛药的使用; 缩短伤口愈合时间。 Postoperative local water-filtered infrared A (wIRA) irradiation improves tissue oxygen partial pressure, tissue perfusion and tissue temperature, which are important in wound healing. Some 111 gastrointestinal surgery patients undergoing moderate to major abdominal surgery were randomized into one of two groups: wIRA and visible light irradiation (wIRA group) or visible light irradiation alone (control group). Uncovered wounds were irradiated twice a day for 20 min from days 2-10 after operation. wound healing assessed on a visual analogue scale (VAS) by the surgeon (median 88.6 versus 78.5 respectively; P 0.001) or patient (median 85.8 versus 81.0; P = 0.040), postoperative pain (median decrease in VAS score during irradiation 13.4 versus 0; P 0.001), subcutaneous oxygen tension after irradiation (median 41.6 versus 30.2 mmHg; P 0.001) and subcutaneous temperature after irradiation (median 38.9 versus 36.4 degrees C; P 0.001). The overall result, in terms of wound healing, pain and cosmesis, measured on a VAS by the surgeon (median 79.0 versus 46.8; P 0.001) or patient (79.0 versus 50.2; P 0.001) was better after wIRA irradiation. Postoperative irradiation with wIRA can improve normal postoperative wound healing and may reduce costs in gastrointestinal surgery. ●A 64 year old female patient had relapsing wound seromas and wound hematomas (without infection) after a hip operation replacement of the acetabulum part of a 15 years old endoprosthesis) even after an additional operation with the only intention to stop the wound seromas and after approximately 8 aspirations of seroma fluid (up to approximately 90 mL within one aspiration) within 2 months, and a third operation was seriously considered: 威伐光伤口积液疗效 威伐光起初 30分钟/次,2次/天,积液开始不再增加,约治疗一周时 积液开始出现明显减少。 威伐光治疗18天后,积液完全消除 威伐光伤口积液疗效 深部穿
