ABSTRACT

Objective: To determine which factors are related to oxygen index variability in patients undergoing cardiac surgery with cardiopulmonary bypass. Design: Retrospective, descriptive, observational analysis. Setting: Hospital de Cardiología Centro Médico Nacional Siglo XXI Mexico City. Patients: 127 adult and infant patients scheduled for cardiac surgery with cardiopulmonary bypass. Interventions: None. Results: The major associated factor to gas exchange impairment after cardiopulmonary bypass is respiratory index. There are no significative correlation with aortic cross clamping time and the length of cardiopulmonary bypass. This relation was not found in patients with septal defects. In patients with IR › 2 we observed an improvement in oxygen indexes while patients with IR ‹ 2 showed an important impairment. Conclusions: The major associated factor to gas exchange impairment after cardiopulmonary bypass is the previous lung condition based on respiratory index.
