Association of postoperative nausea/vomiting and pain with breastfeeding success.

BACKGROUND

Successful breastfeeding is a goal set forth by the World Health Organization to improve neonatal care. Increasingly, patients express the desire to breastfeed, and clinicians should facilitate successful breastfeeding. The primary aim of this study is to determine if postoperative nausea and vomiting (PONV) or postoperative pain are associated with decreased breastfeeding success after cesarean delivery.

METHODS

This is a historical cohort study using the Stony Brook Elective Cesarean Delivery Database. Self-reported breastfeeding success at 4 weeks postoperative was analyzed for associations with postoperative antiemetic use and postoperative pain scores. Breastfeeding success was also analyzed for associations with patient factors and anesthetic medications.

RESULTS

Overall, 86% of patients ( = 81) who intended on breastfeeding reported breastfeeding success. Breastfeeding success was not associated with postoperative nausea or vomiting as measured by post anesthesia care unit antiemetic use (15% use in successful vs. 18% use in unsuccessful,  = 0.67) or 48-h antiemetic use (28% use in successful group vs 36% use in unsuccessful group,  = 0.732). Pain visual analog scale scores at 6, 12 and 24 h postoperatively were not significantly different between patients with or without breastfeeding success. Breastfeeding success was associated with having had at least 1 previous child (86% vs 36%,  < 0.001). Patients with asthma were less likely to have breastfeeding success (45% vs 4%,  = 0.002).

CONCLUSIONS

Efforts to improve PONV and pain after cesarean delivery may not be effective in improving breastfeeding success. To possibly improve breastfeeding rates, resources should be directed toward patients with no previous children and patients with asthma.
