Core Tip
Core Tip: Alveolar recruitment maneuvers (ARMs) may lead to transient hypotension, but clinical characteristics of this hypotension are poorly understood. In the present study, we investigated characteristics of ARM-related hypotension in 140 patients undergoing laparoscopic colorectal cancer resection. The primary endpoint was an ARM-related hypotension. Risk factors for the hypotension were identified. When ARM was repeated intraoperatively, a quarter of subjects developed ARM-related hypotension, but only 3.61% of all the ARMs induced hypotension. ARM-related hypotension events most occurred at a hemodynamic instability or hypovolemic state, and in elderly subjects. Encouragingly, ARMs under pneumoperitoneum conditions had less impact on blood pressure.
