Comparison of the anesthesia effects of nerve stimulator localization and blind exploration method in nerve block / 中国基层医药

ABSTRACT

Objective To compare the clinical effects of neurostimulator positioning nerve block and blind exploration in anesthesia.Methods One hundred and thirty -two patients undergoing upper extremity surgery in the People's Hospital of Xishuangbanna Dai Nationality Autonomous Prefecture were enrolled in this study .According to the digital table,the patients were randomly divided into two groupsblind probing nerve block group ( B group,n＝66) and neurological stimulator locating nerve block group (N group,n＝66).The good rate of anesthesia and compli-cations of the two groups and so on were observed.Results The dosage of anesthetic in B group was (17.6 ± 4.1)mL for anesthesia with 1% lidocaine and 0.375% ropivacaine,which in N group was (18.1 ±4.8)mL,there was no statistically significant difference between the two groups (t＝-0.66,P＞0.05).The good rate of anesthesia in N group was 79.0%,which was higher than that in B group (53.0%),the difference between the two groups was statistically significant(χ2＝9.74,P＜0.05).There were 5 cases(7.6%) turned to general anesthesia because of severe pain in B group,there was no change of anesthesia in N group ,the difference was statistically significant (χ2＝5.20,P＜0.05).The incidence rate of complications in N group was 1.5%,which was lower than 6.1%in B group, the difference was statistically significant (χ2＝4.16,P＜0.05).Conclusion Nerve stimulator has good application value in nerve block anesthesia as a good and cheap tool.
