The efficacy of magnesium sulphate in preventing laryngospasm in paediatric patients undergoing general anaesthesia: A systematic review and meta-analysis of randomised control trials

Laryngospasm is sustained closure of the airways and can be a life-threatening condition. Magnesium sulphate is postulated to reduce the incidence of laryngospasm if administered peri-operatively. This systematic review and meta-analysis was performed to assess the efficacy of magnesium sulphate in preventing peri-operative laryngospasm in paediatric patients undergoing non-cardiac surgery.
