Why the study?
Does the Trendelenburg position affect lower oesophageal sphincter tone in healthy female patients during balanced anaesthesia?
Does the Trendelenburg position affect lower oesophageal sphincter tone in healthy female patients during balanced anaesthesia?
The steep Trendelenburg position does not significantly alter lower oesophageal sphincter tone and should not predispose to regurgitation in healthy patients.
May support Trendelenburg use without regurgitation concern in healthy anaesthetized patients; leaves open effects in other populations or settings.
Measurements were made of gastric, lower oesophageal and barrier pressures in the supine, moderate and steep Trendelenburg positions in 10 healthy female patients during balanced anaesthesia. Adoption of the Trendelenburg position resulted in no significant changes in any measurement, with the exception of a small increase (0.1 kPa) in intragastric pressure in the steep head-down position. We conclude that the steep Trendelenburg position should not predispose to regurgitation in healthy patients.
