Introduction: Breast surgery may be associated with significant postoperative pain and if not adequately treated, may lead to the development of chronic post-surgical pain. This necessitates the use of effective management, involving the use a multimodal analgesia regimen for the management of post breast surgery pain. The analgesic effect of perioperative use of dexamethasone has been explored but findings have been inconsistent. Aim: The aim of this study was to determine the postoperative analgesic enhancing effect of a single preoperative dose of dexamethasone on patients undergoing breast surgery at a tertiary hospital in Ghana. Materials and Methods: This was a prospective, double-blind, placebo-controlled study involving 94 consecutively recruited patients. Patients were randomized into two groups: dexamethasone (n = 47) and placebo (n = 47). Patients in the dexamethasone group had 8mg (2 mL of 4 mg/mL) dexamethasone and those in the placebo group had 2 mL of saline administered intravenously just before induction of anaesthesia. All patients received a standard general anaesthesia with endotracheal intubation.The numerical rating score (NRS), time to first analgesic request and the total opioid consumed in the first 24 h were recorded. Results: Patients receiving dexamethasone had lower NRS scores at all measured time points but this was significant only at 8 h post-surgery (P = 0.037). The time to first rescue analgesia was significantly prolonged in the dexamethasone group (339.26 ± 312.90 min vs. 182.10 ± 166.72 min; P = 0.020).However, the mean total opioid (pethidine) consumed in the first 24 h postoperatively was not significantly different between the dexamethasone and control groups (113.75 ± 51.35 mg vs. 100.00 ± 60.93 mg; P = 0.358). Conclusion: A single preoperative dose of 8mg dexamethasone given intravenously, reduces postoperative pain compared to placebo, significantly reduces the time to first analgesia but not the total opioid consumed in the first 24 h post breast surgery. |
