Influence of different catheterization times on patients with time selecting operation

2008 
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).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.
