Effects and safety of patient-controlled intravenous analgesia in children after congenital ventricular septal defect repairing surgery

Abstract

Objective To assess the effects and safety of patient controlled intravenous analgesia (PCIA) in children after congenital ventricular septal defect (CVSD) repairing surgery. Methods One hundred and eight children with ventricular septal defect were randomly divided into analgesia group (n=54) and routine group (n=54). Children in routine group received routine postoperative management, analgesia group received patient-controlled intravenous analgesia. The VAS was compared between the two groups in different time points. The occurrence of adverse event and adverse reaction was compared in the same time. Results All children finished with the research. Children in analgesia group showed lower VAS at 12, 24, 36 and 48 h after the surgery (P<0.05). The occurrence rate of the adverse event in analgesia group was significantly lower than that in routine group (P<0.05). There was no adverse reactions in analgesia group. Conclusions PCIA is a safe and effective method in children after ventricular septal defect repairing surgery, without adverse event and adverse reactions.
