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.

0bjective To explore the nursing needs of the elders in penury countries and the influencing factors in order to provide suggestions for the improvement of QOL of the elder,and to reach health aging.Methods A total of 623 elders were selected from 8 villages of two penury countries,and the two was by random sampling from five penury counties of Lvliang City.Their nursing needs and influencing factors were assessed by interview and questionnaires.Results The score of nursing needs in penury countries was at a high level,sickness prevention was(3.40 4±0.56),health promotion was(3.30±0.70),nursing of disease was (3.56 4±0.52).r111e main influencing factors were illness,educational background,marital status.sex and average income per month.Conclusions We should aim directly at their features and take effective measures from society-family.individual level to satisfy their nursing needs.
