目的：研究低浓度罗哌卡因预防全身麻醉后留置导尿患者在术后苏醒期躁动的临床效果。方法：选择拟行择期手术全身麻醉后留置导尿患者100例，按随机数字表法分为试验组和对照组，各50例。两组患者均在全身麻醉后选择小一号导尿管留置导尿，试验组在手术结束前30分钟经导尿管注入0.2%罗哌卡因20m l夹毕导尿管15分钟后松开导尿管，观察并记录术后苏醒期患者的躁动分级情况。结果：试验组仅出现轻微躁动8例、不躁动42例，对照组出现4级躁动3例、3级躁动14例、轻微躁动18例、不躁动15例，试验组术后苏醒期躁动分级情况显著优于对照组（P<0.05）。结论：低浓度罗哌卡因可以有效预防全身麻醉后留置导尿患者的术后苏醒期躁动。“,”Objective To study the prevention of patients with indwelling catheterization after general anesthesia with low concentration of ropivacaine in postoperative restlessness.Methods Selected the undergoing operation 100 cases of patients with indwelling catheter after general anesthesia. All of them were randomly divided into experimental group and control group (n=50). Two groups of patients with general anesthesia choose the smaller catheter indwelling catheter. The experimental group in operation over 30 minutes before the catheter injection 20 ml of 0.2% ropivacaine folders complete catheter for 15 minutes after the loose enlighten catheter, observe and record after patients in recovery period of restlessness classification.Results In the experimental group, there were only 8 cases of slight restless, 42 cases of not restless, the control group had dysphoria of grade four were 3 cases, grade three were 14 cases, slight restless were 18 cases, and not restlessness were 15 cases, Postoperative restlessness grading in the experiment group was significantly better than the control group (P<0.05).Conclusion Low concentration ropivacaine can restlessness afterindwelling catheterization in patients after general anesthesia with effective prevention.
