Does ‘Micro Ventilation’ during Cardio Pulmonary Bypass Help in Improving Oxygenation in the Immediate Postoperative Period after Cardiac Surgery?
Journal Title: Journal of Cardiovascular Medicine and Surgery - Year 2018, Vol 4, Issue 1
Abstract
Aims: Lung complications after cardiopulmonary bypass are well described. Various methods have been adopted by surgeons for lung protection. Lung preservation during cardiopulmonary bypass is controversial. In this study we investigated whether ventilation during cardiopulmonary bypass with low tidal volumes helps in improving oxygenation post operatively. Methods and Material: Two groups of patients were studied here, one group was not ventilated during cardiopulmonary bypass (group A) and the other group was ventilated (group B). A total of 50 patients were studied, out of which 25 were not ventilated (Group A) and 25 were ventilated during cardiopulmonary bypass (Group B). The partial pressure of oxygen in arterial blood, arterial oxygen saturation and hours of ventilation were compared in the two groups at various intervals. Statistical Analysis Used: The Statistical software SPSS 15.0 was used for the analysis of the data and Microsoft Word TM and Excel TM have been used to generate graphs and tables. Results: There was no increase in pO2 or saturations in the ventilated group either at time of extubation [P=0.985] or 24 hours after surgery [P=0.944]. There was no significant difference in the total hours of ventilation between the two groups [P=0.678]. Conclusions: There was no significant difference in the measured parameters between the two groups. There is no improvement in lung function by ventilating with low volume tidal ventilation during cardiopulmonary bypass.
