Evaluation of Light Specific Gravity Ropivacaine Combined with Sufentanil in Hip Arthroplasty at An Advanced Age

Abstract

Objective: To observe the effect of light specific gravity ropivacaine combined with sufentanil in elderly patients undergoing hip replacement. Methods :89 elderly patients with hip arthroplasty from July 2019 to September 2020 were randomly divided into experimental group and control group. The experimental group was anesthetized with light specific gravity ropivacaine combined with sufentanil. The control group was anesthetized with equal specific gravity ropivacaine to compare the effect of anesthesia and the incidence of adverse reactions. Results: there was no significant difference in sensory recovery time and motor recovery time between the experimental group and the control group (P>0.05), and the incidence of adverse reactions between the two groups was low. The sensory block time in the experimental group was shorter than that in the control group (PP>0.05). Conclusion: ropivacaine combined with sufentanil subarachnoid anesthesia is more effective in elderly patients undergoing hip arthroplasty, and the safety of the anesthesia scheme is higher, which will not lead to serious adverse reactions during operation. Moreover, the application of the anesthesia scheme can effectively improve the analgesic effect during and after operation, and the clinical application value is high.
