Ketamine to Improve Recovery After Cesarean Delivery - Part 1

Postpartum pain management strategies currently permit opioids for breakthrough pain, but strategies focused on minimizing or eliminating opioids are lacking. In the non-obstetric surgical population, modalities such as intravenous ketamine are well-recognized as effective adjuncts in opioid-reduction strategies for postoperative pain. Although there have been some studies of ketamine exposure in postpartum women without deleterious outcomes noted, these studies in pregnant and lactating women are limited by a lack of information on maternal pharmacokinetics, breastmilk secretion, and clinical effectiveness when used with standard multimodal analgesic approaches. There is also a lack of information on intermediate and long-term outcomes in this setting. This two-part trial will address these knowledge gap by advancing understanding of the safety and efficacy of ketamine and its metabolites in peripartum populations.
