Effects in Breastfed Infants

A double-blind study randomized 160 women receiving an elective cesarean section under spinal anesthesia to receive either sufentanil for patient-controlled intravenous analgesia (standard care) or standard care plus dexmedetomidine. Dexmedetomidine was given as 5 mcg/kg, followed by a continuous infusion of 0.5 mcg/kg per hour until the end of surgery. Patient in this latter group received dexmedetomidine plus sufentanil for patient-controlled intravenous analgesia postoperatively for 2 days. Both groups had 25 mg of dolasetron added to the patient-controlled intravenous analgesia solution and all mothers breastfed their infants. Both groups had good neonatal behavioral neurological assessments on days 1 and 2 postpartum.[1]

Effects on Lactation and Breastmilk

A double-blind study randomized 160 women receiving an elective cesarean section under spinal anesthesia to receive either sufentanil for patient-controlled intravenous analgesia (standard care) or standard care plus dexmedetomidine. Dexmedetomidine was given as 5 mcg/kg, followed by a continuous infusion of 0.5 mcg/kg per hour until the end of surgery. Patient in this latter group received dexmedetomidine plus sufentanil for patient-controlled intravenous analgesia postoperatively for 2 days. Both groups had 25 mg of dolasetron added to the patient-controlled intravenous analgesia solution. Patients who received dexmedetomidine had a shorter time to the first lactation (28 vs 34 hours), achieved exclusive breastfeeding sooner (8 vs 11 days) and had a greater amount of milk on the second day postpartum.[1]
