Effects of glycopyrrolate and cimetidine on gastric volume and acidity in patients awaiting surgery

British Journal of Anaesthesia
P J KeatingD W Watson


Glycopyrrolate or cimetidine was administered before operation to patients undergoing elective surgery. After the induction of anaesthesia, the stomach contents were retrieved and the volume and pH measured. Neither drug diminished the volume of gastric contents compared with control. Glycopyrrolate produced little diminution in hydrogen ion concentration. Cimetidine caused a marked increase in pH with a mean [h+] 3.2 x 10(-3) g litre-1 compared with 1.4 x 10(-2) g litre-1 in the controls and 1.1 x 10(-2) g litre-1 in the glycopyrrolate group. Seventy-seven per cent of the patients receiving cimetidine had a pH greater than 2.5.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
