Randomized Controlled Trial Comparative Study Clinical Trial
Pulsatile and nonpulsatile extracorporeal circulation using Capiox E terumo oxygenator: a comparison study with Ultrox and Maxima membrane oxygenators.
An open randomised, prospective study was undertaken on 90 patients who underwent routine myocardial revascularization. The aim of the study was to demonstrate that the Capiox E polypropylene fiber membrane oxygenator with a conventional single pulsatile/nonpulsatile blood pump for cardiopulmonary bypass (CPB) was comparable in performance to that of the Maxima and the Ultrox membrane oxygenators using a double pump system. The patients were divided into six groups according to perfusion mode and oxygenator type. ⋯ The FiO2 was higher in the Capiox E groups 0.77 (PP) and 0.88 (NP) compared to Maxima/PP (0.66), /NP (0.65) and Ultrox/PP (0.64), /NP (0.63). Reciprocally, the venous saturation was higher in the Ultrox and Maxima groups compared to Capiox E at end of CPB. The study demonstrated that the CapioxE oxygenator with a single blood pump system can compare to the Maxima and Ultrox oxygenators with a double blood pump for CPB with regard to blood handling, oxygenation and fluid balance in routine cardiac surgery.
