ADVERSE EVENTS, RESPIRATORY DEPRESSION
A single bolus of 40 mg/kg of intravenous magnesium can significantly reduce propofol requirements and decrease the incidence of respiratory depression and involuntary body movement. Furthermore, it alleviates the postprocedure pain and allows high patient satisfaction and lower adverse events. Therefore, magnesium could be used as an effective and safe adjuvant agent for ERCP sedation in elderly patients. More research is needed to evaluate and modify the ERCP sedation strategy for elderly patients by using intravenous magnesium.
