ObjectiveTo investigate the effect of artificial colloid on coagulation function in pediatric patients weighing less than 5 kg with congenital heart disease during cardiopulmonary bypass in congenital heart disease surgery by using artificial colloid instead of human serum albumin.MethodsA total of 65 pediatric patients with weight less than 5 kg who underwent congenital heart disease surgery in our hospital from September 2016 to December 2017 were included in the study. They were randomly divided into two groups: an artificial colloid group (the experimental group, n=33) and a human serum albumin combined artificial colloid group (the control group, n=32). Perioperative hemoglobin concentration (Hb), blood products and hemostatic drugs used, postoperative coagulation function index and pleural fluid volume 24 hours after surgery were monitored.ResultsThere was no significant difference in perioperative Hb and chest tube drainage between the two groups. The platelet utilization rate in the experimental group was significantly lower than that in the control group (P<0.05). No significant difference was found in the dosage of other blood products and hemostatic drugs between the two groups during the perioperative period. There was no significant difference in coagulation parameters between the two groups before and after surgery (P>0.05).ConclusionThe use of artificial colloid as colloid priming solution during cardiopulmonary bypass has no adverse effect on coagulation function in pediatric patients weighting less than 5 kg with congenital heart disease.
