Abstract
目的 研究动物皮管快速扩张的效果,为临床应用提供依据.方法 取健康家兔12只,雌雄不限,体重1.5~2.0 kg.在背部脊柱两侧各设计两对皮管,快速扩张组每天扩张囊注水1次,注水量为扩张囊容量的10%~15%,常规扩张组每周扩张囊注水2次,注水量为扩张囊容量的10%~15%.临床应用:6例患者中,2例为膝关节瘢痕挛缩,4例为会阴瘢痕挛缩;每天扩张囊注水1次,注水量为扩张囊容量的10%~15%.结果 动物实验:快速扩张组24个皮管,16个皮管完成扩张,扩张时间7 d,8个皮管因感染、扩张器漏水等原因失败;常规扩张组24个扩张器18个完成全部扩张,4个皮管因感染、1个皮管因扩张器注水困难、1个皮管因扩张器外露未完成扩张.临床应用:6例患者6个皮管完成扩张,注水时间7 d,皮瓣转位修复创面,全部成活.结论 皮管快速扩张是安全可行的。
