Dexamethasone administration to improve patient recovery in ambulatory vaginal reconstructive surgery: a randomized prospective trial.

Introduction And Hypothesis: Dexamethasone is a potent glucocorticoid that may improve quality of recovery (QoR). We hypothesized that standard administration of dexamethasone at induction may improve QoR compared to placebo in subjects undergoing ambulatory vaginal reconstructive surgeries.

Methods: This was a randomized prospective clinical trial on subjects scheduled for ambulatory vaginal reconstructive surgery for prolapse and/or urinary incontinence. Intervention arm subjects were administered dexamethasone and the control group, a placebo (normal saline). Timing of administration, anesthesia medications, postoperative pain medications, and antiemetics were standardized. Primary outcome was difference in QoR (QoR-40) scores 24-48 h after surgery. Power analysis estimated that 27 subjects were required in each group to detect a difference in QoR-40 scores with 80% power and an alpha of 0.05.

Results: Fifty-one subjects were enrolled and randomized. 4 withdrew, 1 was excluded, and 46 were analyzed. For the primary outcome, there was no difference in the QoR-40 between the dexamethasone and placebo group (--13.5 vs -19.6, p=0.24). Postoperative nausea vomiting intensity scores were not different (8.33 vs 9.09, p=1). Pain scores were similar in the two groups (6.0 vs 4.7, p=0.12). Although not statistically significant, surgical satisfaction at 6 weeks was better with dexamethasone (23.5 vs 26.9, p=0.09).

Conclusion: Based on this study, a single dose of dexamethasone at the time of induction prior to ambulatory vaginal reconstructive surgery was not associated with improved QoR. Standardized anesthesia protocols may play a role in postoperative nausea, pain control, and thereby QoR in patients undergoing ambulatory vaginal reconstructive surgeries.
