Cardiac, Anesthesia and Surgical Outcomes

BackgroundGlucocorticoids are commonly administered before ambulatory surgery, although their effects on quality of recovery are not well characterized. The purpose of this study was to evaluate the dose-dependent effects of dexamethasone on patient recovery using the Quality of Recovery 40 questionnaire (QoR-40) after ambulatory surgery.MethodsThis prospective, double-blind trial studied 106 female subjects undergoing outpatient gynaecological laparoscopy. Subjects were randomized to receive saline, dexamethasone 0.05 mg kg−1 or dexamethasone 0.1 mg kg−1 before induction. The primary outcome was global QoR-40 at 24 h. Postoperative pain, analgesic consumption, side-effects, and discharge time were also evaluated.ResultsGlobal median (IQR) QoR-40 after dexamethasone 0.1 mg kg−1 193 (192–195) was greater than dexamethasone 0.05 mg kg−1 179 (175–185) (P=0.004) or saline, 171 (160–182) (P<0.005). Median (IQR) morphine equivalents administered before discharge were 2.7 (0–6.3) mg after dexamethasone 0.1 mg kg−1 compared with 5.3 (2.4–8.8) mg and 5.3 (2.7–7.8) mg after dexamethasone 0.05 mg kg−1 and saline (P=0.02). Time to meet discharge criteria was 30 min shorter after dexamethasone 0.1 mg kg−1 compared with saline (P=0.005). At 24 h, subjects receiving dexamethasone 0.1 mg kg−1 had consumed less opioid analgesics, reported less sore throat, muscle pain, confusion, difficulty in falling asleep, and nausea compared with dexamethasone 0.05 mg kg−1 and saline.ConclusionsDexamethasone demonstrated dose-dependent effects on quality of recovery. Dexamethasone 0.1 mg kg−1 reduced opioid consumption compared with dexamethasone 0.05 mg kg−1, which may be beneficial for improving recovery after ambulatory gynaecological surgery.
