This study designed to evaluate the correlation between the effect of intraoperative magnesium sulfate infusion and the incidence of emergence agitation after pediatric ophthalmic surgery

Emergence agitation (EA) is a frequent postoperative complication in pediatric patients after general anesthesia. There are several suggested causes of EA and pain has been considered one of them. Magnesium is an N-methyl-D-aspartate (NMDA) receptor antagonist and increasingly used as an analgesic-adjuvant. We evaluate the Pediatric Anesthesia Emergence Delirium (PAED) Scale to investigate whether the intraoperative infusion of magnesium sulfate reduces the incidence of EA in pediatric patients who undergo ophthalmic outpatient surgery.

Inclusion Criteria:

• pediatric patients who are planned to operate ophthalmic surgery under general anesthesia aged 4-7 years

Exclusion Criteria:

• ASA class ≥ III
• imbalance of electrolyte
• myocardial damage or conduction abnormality on ECG
• myasthenia gravis or any other neuromuscular disease
• impaired renal function
• denial to participate in study or not be able to give informed consent
