Study of the newborn feeding behaviors and fentanyl concentration in colostrum after an analgesic dose of epidural and intravenous fentanyl in cesarean section.
OBJECTIVE
To compare the effects of epidural and intravenous fentanyl on breast feeding behaviors and fentanyl concentration in the colostrum after an analgesic dose.


METHODS
This study was conducted at the Obstetrics Department of Kasr El-Aini Hospital-Cairo University, Cairo, Egypt. The studied mothers were 100 multipara, who have been subjected to cesarean section, and have a previous history of successful breast feeding. The study was conducted from May 2005 to May 2007. They were divided into 2 groups: group I included 50 patients who received epidural anesthesia with fentanyl, and group II included 50 patients who received spinal anesthesia with intravenous fentanyl, and both groups were observed for initial breast feeding behaviors of newborns, and fentanyl concentration in the colostrum at 45 minutes, and 24 hours after birth.


RESULTS
The study included 100 multipara, 2 samples of colostrum were taken from each patients at 45 minutes, and at 24 hours. The levels of fentanyl concentration were greatest at 45 minutes of the initial sampling time, reaching 0.40+/-0.059 ng/ml in the epidural group, and 0.19+/-0.019 ng/ml in intravenous fentanyl group. There was no statistical difference in breast feeding behaviors at birth, or at 24 hours of age in both groups.


CONCLUSIONS
Although the levels of fentanyl concentration were greatest at 45 minutes of the initial sampling time, it can be used safely as intravenous or epidural without affecting the initial breast feeding behaviors of the newborn.
