Deliberate Compensated Vasoplegia-A Novel Pharmaceutical Approach for Controlling Blood Pressure During Surgery for Pheochromocytoma.

Background: The most dreaded adverse event of pheochromocytoma surgery is operative severe blood pressure fluctuations. Preoperative protocols with alpha-blockade have achieved controversial results. No study to date evaluated the use of operative protocols in pheochromocytoma patients.

Postcardiopulmonary bypass hypoxemia: a prospective study on incidence, risk factors, and clinical significance.

Objective: To evaluate the clinical significance of low arterial oxygen tension-inspired oxygen concentration (PaO2-FIO2) ratio, as a measure of hypoxemia, in the early period after cardiac surgery with cardiopulmonary bypass (CPB); and to evaluate the preoperative, intraoperative, and postoperative factors contributing to the development of hypoxemia within the first 24 hours after cardiac surgery with CPB.

Design: Prospective observational study.

Setting: University hospital.
