Evaluating Pain Control Strategies in Postpartum Patients on Opioid Use Disorder Medications.

Evaluating Pain Control Strategies in Postpartum Patients on Opioid Use Disorder Medications: Efficacy and Safety Outcomes.

The purpose of this study is to investigate the efficacy of three different modalities of post-operative pain control in parturient with opioid use disorders. The investigators aim to determine whether the different approach utilized show better outcomes with pain management and if there are any association with reduction of symptoms of anxiety, depression, and overall well-being.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Transverse abdominal Plane(TAP) Block with long acting Exparel; A subset of participants (n=15) will be divided into three different arms: A.) Postoperative Epidural infusion for 24-36hrs B.) Hydromorphone Patient Controlled Analgesia (PCA) with Preservative free Morphine via epidural for 36hrs C.) Transverse abdominal Plane(TAP) Block with long acting Exparel.	Drug: Regional Anesthesia; Transverse abdominal Plane(TAP) Block with long acting Exparel placed by a regional anesthesiologist.
Active Comparator: Postoperative Epidural infusion for 24-36hrs; A subset of participants (n=15) will be divided into three different arms: A.) Postoperative Epidural infusion for 24-36hrs B.) Hydromorphone Patient Controlled Analgesia (PCA) with Preservative free Morphine via epidural for 36hrs C.) Transverse abdominal Plane(TAP) Block with long acting Exparel.	Procedure: Epidural local anesthetic infusion; Epidural group will receive pain control via a local anesthetic intermediate bolus infusion
Active Comparator: Hydromorphone Patient Controlled Analgesia (PCA),Preservative free Morphine via epidural for 36hrs; A subset of participants (n=15) will be divided into three different arms: A.) Postoperative Epidural infusion for 24-36hrs B.) Hydromorphone Patient Controlled Analgesia (PCA) with Preservative free Morphine via epidural for 36hrs C.) Transverse abdominal Plane(TAP) Block with long acting Exparel.	Drug: Hydromorphone Patient Controlled Analgelsic; This group will be administered epidural PCA as a modality for pain control post cesarian section
