Effects of different anesthesia protocols on lactation in the postpartum period.

OBJECTIVE

Many factors can influence the secretion of breast milk. Cesarean section is a risk factor for late onset of breastfeeding.

MATERIAL AND METHODS

In our study, we compared the lactation process by mothers who underwent elective cesarean section under general anesthesia, spinal anesthesia, epidural anesthesia, and normal birth; 84 patients between 18-40 years of age with a risk of ASA I-II were included. Randomly patients were divided into four groups: group G (general anesthesia, n:21), group S (spinal anesthesia, n:21), group E (epidural anesthesia, n:21), and group V (vaginal birth, without anesthesia, n:21). Oxytocin and prolactin values of all patients before and after operation or birth were recorded. In addition the initiation time of lactation after delivery or cesarean section were recorded.

RESULTS

In all groups, there were no significant differences among hormone levels in the prepartum period (p=0.350). Prolactin levels in group G (p=0.011) and oxytocin levels in group V (p=0.012) in the postpartum period were significantly higher than in the other groups. The start of lactation was significantly delayed in group G (p=0.003).

CONCLUSION

We consider that the onset time of lactation is delayed in patients undergoing cesarean section with general anesthesia when compared with patients who undergo cesarean section with spinal and epidural anesthesia and with patients who undergo normal vaginal birth. Because of the delay of awakening and recovery of cognitive functions in general anesthesia, communication between the mother and the newborn is delayed and so is the lactation.
