不同导尿时机对择期手术患者的影响

目的 探讨不同术前导尿时机对择期手术患者血压、心率及术后苏醒期尿管相关膀胱刺激征发生率的影响.方法 将90例择期手术患者随机分为三组,每组30例.A组为常规导尿组,B组为麻醉前用药15 min后导尿组,C组为麻醉后导尿组.比较三组导尿前、导尿中、导尿后血压、心率的变化,以及术后尿管相关膀胱刺激征的发牛情况.结果 A组的血压、心率在导尿前、中、后3个时段的比较差异有统计学意义(P＜0.05),B,C两组则无统计学意义(P＞0.05);C组尿管相关膀胱刺激征的发生率高于A,B两组,差异有统计学意义(P＜0.05).结论 麻醉前用药15 min后为患者施行导尿,患者的血压、心率较平稳,术后尿管相关膀胱刺激征的发生率较低,是对手术患者影响较小的导尿时机.

Influence of different catheterization times on patients with time selecting operation

Objective To explore the effects of difierent preoperative catheterization times to blood pressure,heart rate and occurrence rate of catheter-related bladder discomfort during postoperative emergence peiled among patients with time selecting operation.Methods 90 patients were randomly divided into three groups,30 patients in each group:the routine catheterization group(group A),the catheterization after premeditation for 15 minutes before anesthesia(group B),and the catheterization after anesthesia(group C).Physiological parameters of subjects(including systolic pressure,SBP;diastolic pressure,DBP;heart rate,HR)Were monitored pre-operatively,intra-operatively and post-operatively;catheter-related bladder discomfort was evaluated at Oh.1h,2h and 6h after operation.Results Blood pressure and heart rate at three measurement times(pre-operatively,intra-operatively and post-operatively)in group A had statistically significant meanings,respectively(P<0.05).There was no difference in group B and group C(P>0.05).The incidence of catheter-related bladder discomfort was higher in group C than that in group A and B(P<0.05).and the difference had obviously statistical meaning(P<0.05).Conclusions Group B (catheterization after premeditation for 15 minutes before anesthesia)has the least effects of blood pressure,heart rate and catheter-related bladder discomfort on patients with time selecting surgery.So catheterization after premedication for 15 minutes before anesthesia is the choice with less influence to the patients.
