Application value of ultrasound guided lumbar plexus sciatic nerve block anesthesia in elderly patients with hip replacement / 中国基层医药

ABSTRACT

Objective To investigate the effect of ultrasound guided lumbar plexus sciatic nerve block anesthesia in elderly patients undergoing hip replacement.Methods From June 2015 to June 2016,84 elderly patients in Taizhou Bone Injury Hospital received hip replacement were randomly divided into 2 groups according to the digital table,with 42 patients in each group.The control group received epidural anesthesia ,the observation group received ultrasound guided lumbar plexus sciatic nerve block anesthesia .The occurrence of adverse reaction ,hemody-namic changes and the effect of anesthesia were observed in the two groups .Results In the control group,the SBP, DBP levels at T2,T3,T4,T5 were lower than those at T0 (t＝3.998,4.042,3.768,3.974,4.505,4.276,4.022, 4.076,all P＜0.05).In the observation group,the SBP,DBP levels at different time had no statistically significant changes(all P＞0.05).The SBP,DBP levels at T2,T3,T4,T5 in the observation group were higher than those in the control group (t＝3.667,3.839,3.997,3.654,3.330,3.675,3.759,3.885,all P＜0.05).The excellent and good rate of anesthesia effect in the observation group was 95.24%,which was significantly higher than 78.57% in the control group,and the difference was statistically significant (χ2＝12.209,P ＜0.05).Conclusion Ultrasound guided lumbar plexus sciatic nerve block anesthesia for elderly patients underwent hip replacement has good effect , and has no obvious influence on hemodynamics ,and with less adverse reactions.
