Efficacy of intravenous magnesium sulfate infusion on postoperative pain and quality of recovery for septorhinoplasty: a randomized controlled study

Abstract

Background The pain that occurs after septorhinoplasty is an important factor affecting the comfort of the patient. Objectives To investigate the effect of perioperative intravenous magnesium sulfate infusion on postoperative pain and quality of recovery in patients underwent septorhinoplasty surgery. Material and methods One hundred twenty patients who underwent septorhinoplasty were randomly divided into two groups. Magnesium group received intravenous magnesium after induction of anesthesia (30 mg/kg), then infused until the end of the surgical procedure (9 mg/kg). The placebo group received the same volume of saline infusion. The VAS score was used for postoperative pain assessment, and the Quality of Recovery-40 (QoR-40) score was used for the assessment of recovery status. Results The postoperative 30 min, 1st, 2nd, 4th (p < .001) and 24th hour (p < .05) VAS scores of the patients in the magnesium infusion group were significantly lower compared to the placebo group. Also; in terms of physical comfort (p < .001), emotional state (p < .05), psychological support, pain and total score values (p < .001), patients in magnesium group had significantly higher QoR-40 scores than those in placebo group. Conclusion Intraoperative magnesium infusion, which is widely used in many surgeries to provide controlled hypotension, also contributes significantly to patient comfort with its positive effect on postoperative pain and recovery scores.
