The Clinical Comparative Study on Lumbar-epidural Anesthesi and Epidural Anesthesia in Senile Total Hip Arthroplasty

Objective To investigate lumbar-epidural anesthesia and epidural anesthesia in senile total hip arthroplasty.Methods All 40 cases of hip arthroplasty in elderly patients were divided into the lumbar-epidural anesthesia group(A,n=20)and epidural anesthesia group(B,n=20)from April 2009 to April 2011.Recording the onset time of anesthesia.Monitoring the mean arterial pressure(MAP),heart rate(HR)before and after anesthesia 5min,10min,30min anesthesia.Recording the number cases of sedative and vasoactive drugs.Results The anesthesia onset time of A group was shorter than B group,the difference was statistically significant(P0.05).The MAP of two groups before and after anesthesia 5min,l0min,30min was no statistically significant(P0.05).A group had less sedatives than B group,but more vasopressors more than the number of cases in B group.The VAS score was less in B group and the difference was statistically significant(P0.05).Conclusion Two kinds of anesthesia methods were relatively small on hemodynamic,but the effective time of lumbar-epidural anesthesia was shorter than epidural anesthesia.Meantime,the use of sedatives drugs was less.It is suitable for elderly patients with hip replacement surgery.
