Summary

The purpose of this research is to study serious clinical problems from both surgical pain and oxycodone and opioid use in women having a Cesarean Delivery to improve the safety and efficacy of surgical pain relief. This research will ultimately improve the safety and efficacy of surgical pain relief with opioids by preoperative risk predictions and personalized care with the right dose of the right analgesic for each patient.

Description

The overall objective is to determine the impact of risk factors on oxycodone and other opioid's adverse postoperative outcomes and to personalize dosing in women having a Cesarean Delivery. For the purpose of this study, immediate adverse postoperative outcomes are characterized as Respiratory Depression (RD), Postoperative Nausea and Vomiting (PONV), and inadequate surgical pain relief. Long-term adverse postoperative outcomes are characterized as Chronic Persistent Surgical Pain (CPSP) and Opioid Dependence (OD).

The central hypothesis is that specific genetic factors in pain-opioid pathways significantly impact oxycodone and opioid dosing, analgesia, immediate adverse effects (RD and PONV), and long-term adverse outcomes (CPSP and OD) along with known non-genetic risk factors.

The aims of this project are to validate genetic variants and to develop a test for preoperative risk prediction in lactating mothers and breastfed babies following cesarean delivery (CD). There is an urgent and unmet critical need for reliable technology to improve safety and effectiveness of opioid use in special populations.

Aim 1. Validate and identify genetic risk factors associated with postoperative opioid adverse effects, PONV and RD in adult nursing mothers following CD.

Investigators hypothesize that with standardized and genotype-blinded perioperative care, specific variants will identify nursing mothers at risk for opioid-induced RD and PONV (primary outcome), OD and severe pain following CD. In addition, genetic variants will identify risk for opioid-induced sedation and adverse effects in breastfed infants. In addition to clinical outcomes, the investigators will collect post-CD cost of care including length of stay.

Aim 2. Develop a laboratory-developed test (LDT) at University of Pittsburgh Genome Center (UGC) for preoperative genetic risk prediction and decision support for surgical patients to prevent adverse opioid outcomes. Investigators will develop a minimum viable product (MVP) (CPT code: 81227), a refined multi-gene panel in UGC's CLIA certified laboratory with a robust combinatorial pharmacogenetic decision support to personalize surgical analgesia with precise opioid use in children and adults, and to prevent RD, PONV, CPSP and OD.
