The effect of the type of anesthesia on the quality of postoperative recovery after orthopedic forearm surgery

Abstract

Background

Although the quality of postoperative recovery may be affected by factors, there are few investigations whether the type of anesthesia also affects it. In this single-blinded, prospective, observational study, we compared the quality of postoperative recovery in patients undergoing orthopedic forearm surgery under general or regional anesthesia (brachial plexus block).

Methods

Ninety-seven subjects, aged 18–65 years and American Society of Anesthesiologists physical status I or II, undergoing orthopedic forearm surgery, were allocated to general or regional anesthesia group. The quality of postoperative recovery was assessed using a validated Korean version of Quality of Recovery-40 (QoR-40K) questionnaire. Patients were surveyed three times, the day before surgery (baseline) and 1st and 7th day after the surgery, and the scores of both groups were compared.

Results

We analyzed 47 and 50 patients in general and regional anesthesia, respectively. The global QoR-40K score and those of each of its five dimensions were not significantly different between the two groups at baseline, 1st and 7th day postoperatively. In two-way RM ANOVA, the global QoR-40K score at postoperative 1st day was significantly lower than that of baseline (P < 0.001) and postoperative 7th day (P < 0.001), respectively, in both general and regional anesthesia groups. However, there was no significant difference at each timepoint between the two groups.

Conclusions

The present study suggests that brachial plexus block with intravenous dexmedetomidine infusion does not improve the quality of postoperative recovery compared to sevoflurane inhalation anesthesia with remifentanil infusion in patients undergoing orthopedic forearm surgery.
