Introduction:Caesarean section is accompanied with higher risks for mother and baby in comparison with vaginal delivery. The incidence rate of jaundice and cesarean section in recent decades has increased significantly. The aim of this study was to evaluate the relationship between the type of delivery and the jaundice severity in newborns.
Methods: This descriptive-analytical study was performed on infants with asymptomatic jaundice as the chief complaint who referred to Ghaem hospital in Mashhad, between 2002 and 2009. Complete physical examination and laboratory tests were performed for infants. History of pregnancy and delivery pattern, time of jaundice onset, age at discharge, chief complaint on admission, associated symptoms, duration of hospitalization and treatment were recorded. Eligible infants with idiopathic jaundice were divided into two groups based on the delivery type (normal vaginal delivery and cesarean section). Data were analyzed by Chi-square test, Mann-Whitney test and Kruskal-Wallis test using SPSS 11.5 software.
Results: 41.9 percent of newborns with jaundice were born by cesarean section and 58.7 percent were boys. Age and weight at admission, age of jaundice onset and neonatal weight within days 3 to10 was not significantly different between the two groups (p>0.05), while maternal age, birth weight and pregnancy complications showed significant differences (p<0.05). Mean serum bilirubin was 21.3± 4.2 in normal vaginal delivery group and 20.7 ± 4.4 mg/dl in cesarean section group.
Conclusion: There is no relationship between the type of delivery and the severity of jaundice in newborns, based on the findings of this study.
