Hypotension during bypass increases stroke risk
March 23, 2017
Hypotension during cardiopulmonary bypass surgery is linked to increased risk of post-surgical cardiovascular accidents, according to researchers in Canada.
The team at University of Ottawa in Ontario conducted a retrospective cohort study of over 7000 patients who required a cardiopulmonary bypass. They found that cardiovascular accidents were more common in patients with a mean arterial pressure less than 75 mmHg during surgery.
Other risk factors for cardiovascular accidents included older age, cooling while on bypass, and combined valve and bypass surgery.
