Description
Xiaoxi Liu, with six colleagues, reports a 2026 trial of two breathing machine modes for older patients in tilted keyhole surgery. In the Trendelenburg pose, the body tilts head-down, and gas in the belly pushes on the lungs. Lung problems after surgery are common in this group, so the mode of air delivery matters.
Patients were assigned at random to pressure-controlled or volume-controlled modes, both under a lung-safe plan. Lung problems in the first three days struck 13.0 percent of the pressure group against 32.1 percent of the volume group. Airway pressures ran lower with pressure control, and lung stretch, a measure of how freely lungs fill, ran higher. Carbon dioxide in the blood also sat lower. The authors say larger trials must show whether these gains change real recovery.
