皮肤软组织扩张术中局部给药新途径的临床应用

为了皮肤扩张术顺利进行，缩短扩张时间、减少并发症，设计了同时放置埋入式药物注入器，以便随时在扩张过程中向局部注入强地松龙、普鲁卡因等药物的新方法，通过临床应用组与对照组比较，结果证明效果确切，方法简便实用，值得推广。

Local administration of drug during tissue expansion

In order to shorten the expansion time and reduce complications in tissue expansion,we developed a new method using local delivery of drug during tissue expansion.The procedure commenced with placing an implant syringe between the skin and the expander.While the skin was expanded,the drugs such as prednisolone and procaine were injected under the skin from the implant syringe.We have used the method in 23 cases and compared the results with the control group of 11 cases.It was found that the new method shortened the expansion time and reduced complications.The method had definite effect and the manipulation was simple and convenient.We conclude that the method is of value to assist tissue expansion and is worth employing routinely.
