The Effect of Neuraxial Analgesia on Maternal Breastfeeding
In Brief
A clinical study evaluating Group 1, Group 2, and 1 other intervention for Pain and Breastfeeding. Completed, enrolled 345 participants across 1 site.
Detailed Summary
A previous randomized trial showed a possible negative association with labor neuraxial analgesia with high compared to low doses of fentanyl, and breastfeeding at 6 weeks postpartum. The significance of this study would be to validate or refute these findings. In addition, we hope to better evaluate the impact of cumulative dose of fentanyl on breastfeeding success in the initial postpartum period as well as at 6 weeks and 6 months post delivery. In order to better assess the quality of breastfeeding, we will utilize a validated breastfeeding assessment tool, LATCH (Latch, Audible swallowing, Type of Nipple, Comfort, and Help). This validated tool can assess maternal and infant variables, define areas of needed intervention, and determine priorities in providing patient teaching. The LATCH assessment has been shown to be a predictor of breastfeeding duration. We also plan to vary the dosage of fentanyl analgesia to determine the relationship between doses below 150 micrograms and changes in breastfeeding assessments. If a clear association between decreased breastfeeding and total fentanyl is identified, then regimens to reduce cumulative doses of fentanyl can be developed to improve the likelihood of breastfeeding success in mothers that desire to breastfeed. Prior observational studies have inferred epidurals negatively affect breastfeeding by decreasing maternal plasma oxytocin release which may adversely affect infant neurobehavioral development. In a study by Beilin et al., it was reported that mothers receiving a high cumulative dose (\> 150 microgram) epidural fentanyl were more likely to have stopped nursing 6 weeks postpartum compared with groups receiving no fentanyl or those receiving \< 150 microgram. The study however, was underpowered to detect differences in breastfeeding prior to hospital discharge. In addition, the breastfeeding assessment tool utilized resulted in binary assessments, and therefore, a global rating of the quality of breastfeeding was not available.

Timeline
Interventions
A basal infusion rate for the PCEA will be set at 8 mL/h with patient administered boluses of 8 mL every 10 minutes and a one hour limit of 32 mL. Breakthrough pain in all groups will be managed using anesthesiologist administered boluses of bupivacaine 1.25 mg/mL without fentanyl.
