Abstract

Background and aim: The immunosuppressive action of dexamethasone may help reduce the risk of postoperative complications such as infection, adhesion formation, and delayed wound healing. Dexamethasone may mitigate tissue damage and hasten recovery by attenuating the inflammatory response, modulating immune cell activity, and reducing the release of pro-inflammatory cytokines. In this first randomized trial of dexamethasone in robotic hysterectomy, we aimed to evaluate its effect on reducing C-reactive protein (CRP) as a proxy marker of surgical stress.

Methods: Women scheduled for robotic-assisted hysterectomy were recruited into a randomized trial comparing a preoperative dose of 24 mg dexamethasone with placebo. Blood tests were obtained, and visual analogue scale scores for pain, postoperative nausea and vomiting, and medication use during admission were recorded at 0, 4, 8, 12, and 24 h postoperatively.

Results: Among the 112 included women, postoperative CRP levels were lower in the dexamethasone group at 12 and 24 h. Postoperative nausea and vomiting over time were also reduced in the dexamethasone group (p = 0.039 without adjustment; p = 0.02 with adjustment). Changes in CRP were analyzed using repeated-measures analysis, showing highly significant differences both without and with adjustment for BMI, age, and baseline CRP (both p < 0.001). Overall, the dexamethasone group demonstrated substantially lower CRP levels during the postoperative period.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 112 participants or records.
