OBJECTIVES: To test whether targeted therapeutic mild hypercapnia (TTMH) would attenuate cerebral oxygen desaturation detected using near-infrared spectroscopy during cardiac surgery requiring cardiopulmonary bypass (CPB). DESIGN: Randomized controlled trials. SETTING: Operating rooms and intensive care unit of tertiary hospital. PARTICIPANTS: The study comprised 30 patients undergoing cardiac surgery with CPB. INTERVENTIONS: Patients were randomly assigned to receive either standard carbon dioxide management (normocapnia) or TTMH (target arterial carbon dioxide partial pressure between 50 and 55 mmHg) throughout the intraoperative period and postoperatively until the onset of spontaneous ve..View full abstract
