SPINAL ANESTHESIA WITH ROPIVACAINE FOR LOWER LIMB SURGERY

Abstract

Objectives: To evaluate the anesthetic effect and impacts on respiration, circulation, and some undesirable consequences of spinal anesthesia with ropivacaine in patients who are scheduled for lower limb surgery. Methods: A clinical interventional study, a randomized group with comparative analysis on 70 patients who were indicated for lower limb surgery at the Department of Surgery - Anesthesia and Resuscitation, Military Hospital 121, Military Region 9 (Can Tho province) from November 2022 to June 2023, randomly divided into 2 groups: Group R (35 patients treated with ropivacaine) and group B (35 patients treated with bupivacaine). Evaluate and compare the criteria of anesthetic effects, intraoperative movement inhibition, and postoperative pain relief. Record the effects of some criteria on circulation, respiration, and unwanted effects related to the anesthetic method. Results: All patients in both groups achieved a good level of anesthesia. In lower limb surgery, the effective pain relief time following spinal anesthesia with ropivacaine was 145.09 ± 7.03 minutes, and the movement inhibition duration was 97.60 ± 7.10 minutes. The effects of ropivacaine on circulation and respiration were minimal, and its side effects, such as bradycardia (5.71%), hypotension (2.86%), and shivering (2.86%), were mild, temporary, and readily managed. Conclusion: Ropivacaine provided effective and safe spinal anesthesia for lower limb surgery, and short-term mobility, and provided pain relief postoperatively. It caused some modest, temporary side effects that were easily managed, but it had little influence on breathing and circulation.
