小剂量不同浓度罗哌卡因在腰硬联合麻醉前列腺电切术中的效果对比

Comparison of Effects of Low Dose Ropivacaine with Different Concentrations Combined Spinal-epidural Anesthesia during Prostatic Electrocision

目的探讨小剂量不同浓度罗哌卡因在腰硬联合麻醉前列腺电切手术中的麻醉效果。方法选择2015年2月~2017年10月90例行前列腺电切手术患者,运用随机数字表法将其分为对照组与实验组,各45例。对照组予以2ml 0.75%的罗哌卡因,实验组予以2ml1%的罗哌卡因,观察两组患者的阻滞持续时间、麻醉前后的心率、血压与麻醉效果情况。结果麻醉前,两组患者的SBP、DBP、心率比较,差异无统计学意义(P>0.05);麻醉后,实验组患者心率为(64.21±5.14)次/min,SBP(119.62±7.31)mmHg,DBP(79.41±9.06)mmHg,各指标均低于对照组的心率(71.53±5.83)次/min,SBP(126.94±8.64)mm Hg,DBP(85.92±7.53)mmHg,组间差异有统计学意义(P<0.05);实验组的阻滞持续时间为(35.46±5.34)min,长于对照组的(26.57±1.09)min,差异有统计学意义(P<0.05)。结论小剂量高浓度的罗哌卡因在腰硬联合麻醉前列腺电切手术中阻滞持续时间长,患者生命体征稳定,阻滞持续时间,具有较高的临床应用价值。

Objective To investigate the anesthetic effect of low dose ropivacaine in combined spinal-epidural anesthesia for prostatic electrocision.Methods From February 2015 to October 2017,90 patients undergoing prostatic electrocision were divided into control group(n=45)and experimental group(n=45).The control group was given 2 ml 0.75%ropivacaine and the experimental group was given 2 ml 1%ropivacaine.The duration of block,heart rate,blood pressure and anesthetic effect before and after anesthesia were observed.Results Before anesthesia,there was no significant difference in SBP,DBP and heart rate between the two groups(P>0.05).After anesthesia,the heart rate of the patients in the experimental group was(64.21±5.14)times/min,SBP(119.62±7.31)mmHg,DBP(79.41±9.06)mmHg,all the indexes were lower than that in the control group(71.53±5.83)times/min,SBP(126.94±8.64)mmHg,DBP(85.92±7.53)mmHg,the difference between groups was statistically significant(P<0.05);The duration of block in the experimental group was(35.46±5.34)minutes,which was longer than that in the control group(26.57±1.09 min),the difference was statistically significant(P<0.05).Conclusion The low dose and high concentration of ropivacaine has a long period of prolonged block in the operation of the combined lumbar epidural anesthesia,and the patient's vital signs are stable and the duration of the block has been blocked.It has a high clinical value.
