摘要
目的 观察皮肤伸展术对猪创周皮肤所形成皮瓣成活的影响。方法 在 4只猪的胸背部制成6cm× 1 0cm矩形创口 ,采用皮肤伸展术于伤后 5～ 6天用 4号丝线缝合关闭创口。分别于缝合后 2周和 3周在距愈合线两侧 4cm和 1 0cm处分别形成 4cm× 1 0cm的矩形皮瓣 ,蒂部在背侧。靠近愈合线者为实验组 ,远者为对照组 ,同时以另 1头猪的正常皮肤处作正常对照。结果 正常组、实验组和对照组三者之间皮瓣成活长度无明显差异。结论 皮肤伸展术虽然能增加局部的血液循环 ,但在伴有皮肤创口的情况下 。
Objective To observe the effect of the skin stretch on the survival of skin flap that was elevated around the wounds. Methods Rectangle wound of 6cm×10cm was created on the back of 4 pigs. The wound was closed with silk sutures after stretched for 5-6 days. Skin flaps of 4cm×10cm were elevated after the wound was closed 2 and 3 weeks. The pedicle of skin flap was at the back side. The distance between the skin flap and the wound suture line were 4cm and 10cm respectively. The same size skin flap was elevated at the non-stretched region of another one pig served as a control. Results There was no significant difference in the survival length of the flap among experimental groups and control group and normal control group. Conclusion Although skin stretch can improve the blood circulation in local area,but the survival time of the flap that located on the stretched area around the wound could not be legnthened.
