摘要
目的探究不同比重浓度的罗哌卡因用于足踝部手术患者的镇静效果对比。方法选择2015年1月～2016年1月间我院在腰丛联合坐骨神经阻滞麻醉下行足踝手术的患者120例作为研究对象，随机分为观察组和对照组，两组各60例，观察组采用0．25％罗哌卡因麻醉，对照组采用0.50％罗哌卡因麻醉，记录手术前、手术中10min、30min以及术毕时的OAMS评分、血流动力学参数，并且观察两组患者的术后不良反应的发生情况。结果在手术开始后10min、30min以及术毕时，观察组的OAMS评分显著低于对照组（P〈0．05）；两组患者术前的MAP、HR比较均无显著差异（P〉0．05）；两组患者在术后30rain的MAP与HR数值比较，差异均有统计学意义（P〈0．05）：并且观察组术毕的HR显著低于对照组（P〈0．05）；观察组术后不良反应发生率为1．67％，对照组术后不良反应发生率为15．00％，两组差异具有统计学意义（P〈0．05）。结论针对于老年行足踝关节手术，选用0．25％罗哌卡因相比较0．50％罗哌卡因安全可靠，同时可以保持良好的麻醉效果并且减少了血流抑制效应，在一定程度上减少了术后不良反应发生率。
Objective To explore and compare the sedative effects of ropi.vacaine with different specific gravity and concentrations on the patients receiving foot and ankle surgery. Methods 120 patients who were received foot and ankle surgery under the anesthesia of lumbar-sciatic nerve block from January 2015 to January 2016 were selected as research subjects. They were randomly assigned to the observation group and the control group, with 60 patients in each group. The observation group was given 0.25% ropivacaine for anesthesia, and the control group was given 0.5% ropivacaine for anesthesia. OAA/S scores, and hemodynamic parameters were recorded before the surgery, 10 min and 30 min during the surgery, and after the surgery, and the postoperative adverse reactions were observed between the two groups. Results 10 min and 30 rain after the beginning of the surgery and after the surgery, OAA/S scores in the observation group were significantly lower than those in the control group （P〈Oo05）; pre-operative MAP and HR were not significantly different at each time point in the two groups of patients （P〉0.05）; there were significant differences of HR and MAP values in the two groups 30 rain after operation （P〈0.05）; HR after the surgery in the observation group was lower than that in the control group （P〈0.05）; the incidence rate of postoperative adverse reactions in the observation group was 1.67%, and the incidence rate of postoperative adverse reactions in the control group was 15.00%. The differences between the two groups were statistically significant（P〈0.05）. Conclusion For foot and ankle surgery for elderly patients, 0.25% ropivacaine is safer and more reliable than 0.5% ropivacaine. It is at the same time able to maintain favorable anesthetic effects and reduce blood flow inhibition effects, which reduces the incidence rate of postoperative adverse reactions to some degree.
