Title: Effect of sufentanil combined with small dose ropivacaine in spinal anesthesia for elderly patients
Abstract: Objective To analyze the effect of sufentanil combined with small doses ropivacaine in spinal anesthesia of elderly patients.Methods Seventy-five patients who were endured with benign prostatic hyperplasia were randomly divided into A,B,C group.Group A was treated with 0.75%ropivacaine 7.5 mg,group B with 0.75% ropivacaine 7.5 mg+sufentanil 5 μg,group C with 0.75% ropivacaine 5.0 mg + sufentanil 5 μg.Anesthesia,circulation,the extent of movements and complications were evaluated during the spinal anesthesia of different groups.Results All the patients obtained successful spinal anesthesia,and there were no patients withdrawn from the study.Group C obtained the most stable MAP value(P 0.05).Group C obtained the most stable HR value(P 0.05).SpO_2 value among the time points showed significant difference(P0.05),but inter-group,the time point interaction were not statistically significant(P 0.05).VAS among three groups of patients showed statistic significance(P0.05),inter-group and inter-group interaction · point showed no significant difference(P0.05).Group C was superior to group A and B,group B was better than group A in the average time to reach the plane,pain retreating T_(12) time than the duration of sensory block(PC0.01).Conclusion Sufentanil combined with small dose ropivacaine for spinal anesthesia in elderly patients produced effect in short time,the dose is small,the analgesic effect is obvious,and there are no significant side effects.
