简易膀胱容量压力测定技术的正交试验研究及在神经源膀胱管理中的效果观察

目的 观察简易膀胱容量压力测定技术在神经源性膀胱管理中的应用效果.方法 将40例神经源性膀胱患者随机分为对照组和试验组各20例,对照组常规依据患者膀胱残余尿量定间歇导尿时间和频次,试验组通过优化的简易膀胱测容量压力测定确定患者膀胱安全容量,依据膀胱安全容量及残余尿量确定间歇导尿时间和频次.观察两组患者的初次排尿时间、结束间歇导尿时间、膀胱容量、残余尿量及泌尿系感染情况.结果 试验组患者初次排尿时间和结束间歇导尿时间都早于对照组(P<0.01);膀胱容量更接近正常成人,残余尿量小于对照组(P<0.01);试验组患者尿路感染率明显低于对照组,有统计学意义(P<0.05).结论 神经源性膀胱患者依据优化的膀胱容量压力测定技术确定膀胱安全容量结合残余尿量进行间歇导尿更安全、有效.

A study on the orthogonal test of simple bladder capacity pressure measurement technique and the effect observation of neurogenic bladder management

Objective To observe the effect of modified simple bladder capacity pressure measurement technique in neurogenic bladder management. Methods Forty neurogenic bladder patients were randomly assigned into control group and experiment group,and each group had 20 cases. In control group intermittent catheterization time and frequency were determined by residual urine volume in a pa-tient′s bladder,while in experiment group the safe capacity of a patient′s bladder was measured by improved simple bladder capacity pressure measurement,and then intermittent catheterization time and frequency were determined by the safe bladder capacity and resid-ual urine volume. First micturition time,the end of the time of intermittent catheterization,bladder capacity,residual urine volume and urinary infection of two groups were observed. Results First micturition time and the end of intermittent catheterization time of patients in the experiment group were earlier than the time of the control group (P<0. 01). Bladder capacity of patients in the experiment group was closer to that of normal adults,and residual urine volume was less than control group (P<0. 01). The rate of urinary tract infection was significantly lower in experiment group than in control group,which was statistically significant (P<0. 05). Conclusions Im-proved bladder capacity pressure measurement technique can be used to determine safe bladder capacity,and together with residual u-rine volume,is used for determining intermittent catheterization for neurogenic bladder patients,which is safer and more effective.
