Abstract
目的 探讨冲洗液温度变化对经尿道膀胱肿瘤气化电切术后膀胱痉挛的影响,以选择最佳的冲洗液温度.方法 177例患者分为5组,5组冲洗液温度分别为15,20,25,30和35 ℃.各组的其他治疗相同.每个患者从术后第1天起每天留3次尿标本(8∶00,16∶00,24∶00),行尿红细胞计数检查,取其平均数作为当天的红细胞数.对各组内膀胱痉挛发生的次数、第1次冲洗前后心率血压的变化值以及术后每天冲洗液的红细胞数进行临床观察.结果 随着冲洗液温度的升高,膀胱痉挛的次数呈下降趋势;随着冲洗液温度的升高,冲洗前后血压和心率的变化值逐渐减小;25 ℃和30 ℃ 2组冲洗液中红细胞数明显低于其他3组(P＜0.05).结论 术后患者出现心率、血压升高提示膀胱痉挛的发生或将要发生;30 ℃膀胱冲洗液应为经尿道膀胱肿瘤气化电切术的最佳选择。
