bloating, constipation, rash, nausea, vomiting
SECONDARY
Data were gathered by a checklist including baseline and post randomization variables. Baseline characteristics were age, sex, gestational age, and baseline blinrubin level. Also, bilirubin level at 12, 24, and 48 hours after admission and side effects including nausea, vomiting, constipation, bloating, and skin rash were assessed as post randomization variables in the two groups. To measure serum bilirubin, arterial blood samples were taken from the neonates and transferred to the single laboratory and was performed by colorimetric assay using 2 and 4-dichloroaniline (DCA) in a 3500BT device. We considered the change of TSB level from baseline as the primary outcome and the difference in length of hospitalization as the secondary outcome.
