Abstract

Different models of membrane oxygenators (MO group) and of D-700E bubble oxygenators (BO group) were comparatively studied in 24 patients with extracorporeal circulation valve surgery on the basis of several evolving variables such as: lenght of ischemic heart arrest, conciousness recovery time, intubation time, lenght of stay at surgical ICU, diuresis, postoperative bleeding, arrhythmias and postoperative complications, and surgery economic cest for each group. The study revealed a significant increase (p > 0.05) of lenght of stay at hospital in the BO group (14 ± 7 days) whereas this parameter was lower in MO group (8 ± 3 days). Arrhytmias were observed in 69 % of perfused patients with BO at the starting of reperfusion but this figure dropped to 38 % in patients treated with MO. Unit cost per BO patient was 1 124.48 and bed day cost was 1 145.24 whereas unit cost per MO patient was 642.56 and bed day cost 97.28. These results showed the economic and recovery advantages reported in the use of membrane oxygenators.
