Systemic effects of carbon dioxide insufflation technique for de-airing in left-sided cardiac surgery.
OBJECTIVE: Systemic effects of carbon dioxide (CO(2)) insufflation during left-sided cardiac surgery were evaluated in a prospective randomized study, with regard to acid-base status, gas exchange, cerebral hemodynamics, and red blood cell morphology. METHODS: Twenty patients undergoing elective left-sided cardiac surgery were randomized to de-airing procedure either by CO(2) insufflation techniqu
