Comparative study between magnesium sulphate and L-hyoscyamine on duodenal motility during ERCP under general anaesthesia: A prospective randomized study

Magnesium sulphate is a safe spasmolytic agent during general anaesthesia that improves the success rate of ERCP and it allows easy completion of the procedure by decreasing the duodenal motility. It decreases the duration of the procedure, subsequently shortens the period of anaesthesia and improves post procedure recovery. It reduces post ERCP pancreatitis, nausea and vomiting.
