Summary
This randomized, double-blind, controlled trial investigates the effect of intraoperative magnesium sulfate infusion on the incidence of postoperative emergence agitation in adult patients undergoing elective lumbar microdiscectomy under general anesthesia. Eligible participants (ASA physical status I-II, aged 18-70 years) will be randomly assigned to receive either magnesium sulfate or 0.9% saline during surgery. The primary outcome is the incidence of emergence agitation in the post-anesthesia care unit (PACU), assessed at admission and at 5, 10, 15, and 30 minutes using the Ramsay Sedation Scale. Secondary outcomes include postoperative pain scores (Numeric Rating Scale), intraoperative remifentanil consumption, recovery and extubation times, tramadol use in the PACU, and any adverse events related to magnesium infusion.
