Clinical application of pulsatile perfusion during cardiopulmonary bypass in pediatric heart surgery.
The benefits of pulsatile over nonpulsatile perfusion has been widely debated in pediatric cardiac operations with cardiopulmonary bypass (CPB). To evaluate the role of pulsatile perfusion in pediatric complicated patients with congenital heart disease undergoing open heart surgery, we performed pulsatile CPB and compared several effects with nonpulsatile perfusion. Pediatric patients (n = 24) diagnosed as typical tetralogy of Fallot (TOF) were randomly divided into two groups: pulsatile perfusion (PP) group and nonpulsatile perfusion (NP) group. ⋯ Free plasma hemoglobin concentration in PP group at preclamp off and CPB weaned off were higher than that of NP group (p < 0.05). Pulsatile perfusion can be successfully applied in pediatric perfusion. Pulsatile perfusion had the role of reducing concentration of inflammatory media in pediatric patients.
