Study of cardiopulmonary bypass in 115 pediatric patients

Objective：Research of cardiopulmonary bypass of pediatric patients with congenital heart disease. Methods：115cases were divided to two groups.group A（n=61） were performed CPB with uncertain tubing system and group B（n=54） with certain tubing system.Group A and B were both primed with Ring's and colloid.Results：There were no difference in age，body weight between group A and B.The crystalloid prime volume in group B was less than it in group A（P＜0.01）.Also in group B，the total volume and the blood prime volume were much less than those in group A （P＜0.01）.Beside these，The intubation time and ICU days for patients in group B were shorter than in group A （P＜0.01）．Conclusion：It plays an very important roll in CPB technique that the certain tubing system，low prime volume and good membrane oxygenator in pediatric patients.
