Review Meta Analysis
Magnesium sulfate for postoperative complications in children undergoing tonsillectomies: a systematic review and meta-analysis.
Previous systematical reviews showed that systemic magnesium decreased postoperative pain and reduced morphine use without any reported serious adverse effects in adults. However, studies in children yielded different results. So we conducted a systematic review to evaluate the impact of magnesium sulfate on postoperative complications in children undergoing tonsillectomies. ⋯ Unlike the studies in adults, this review shows there is no statistically significant effect of perioperative use of magnesium in the postoperative pain control in children undergoing tonsillectomies. But it seems has benefits in reducing rescue analgesia, emergence agitation incidence, and laryngospasm.
