Associations between postpartum pain type, pain intensity and opioid use in patients with and without opioid use disorder: a cross-sectional study

Consensus statement on pain management for pregnant patients with opioid use disorder from the Society for Obstetric Anesthesia and Perinatology, Society for Maternal-Fetal Medicine, and American Society of Regional Anesthesia and Pain Medicine

Pain management in pregnant and postpartum people with an opioid use disorder requires a balance among the risks associated with opioid tolerance, including withdrawal or return to opioid use, considerations around the social needs of the maternal-infant dyad, and the provision of adequate pain relief for the birth episode that is often characterized as the worst pain a person will experience in their lifetime. This multidisciplinary consensus statement from the Society for Obstetric Anesthesia and Perinatology, the Society for Maternal-Fetal Medicine, and the American Society of Regional Anesthesia and Pain Medicine provides a framework for pain management in obstetrical patients with opioid use disorder. The purpose of this consensus statement is to provide practical and evidence-based recommendations and is targeted to healthcare providers in obstetrics and anesthesiology. The statement is focused on prenatal optimization of pain management, labor analgesia and postvaginal delivery pain management, and postcesarean delivery pain management. Topics include a discussion of nonpharmacologic and pharmacologic options for pain management, medication management for opioid use disorder (eg, buprenorphine, methadone), considerations regarding urine drug testing and other social aspects of care for maternal-infant dyads, and a review of current practices. The authors provide evidence-based recommendations to optimize pain management while reducing risks and the complications associated with opioid use disorder in the peripartum period. Ultimately, this multidisciplinary consensus statement provides practical and concise clinical guidance to optimize pain management for people with opioid use disorder in the context of pregnancy to improve maternal and perinatal outcomes.

Antepartum multidisciplinary approach improves postpartum pain scores in patients with opioid use disorder

OBJECTIVES

Pregnancies affected by opioid use disorder (OUD) face difficulties with postpartum pain control. This study aims to determine if prenatal anesthesia consultation for patients on medication for opioid use disorder (MOUD) affects maternal postpartum pain control.

METHODS

This is a retrospective cohort study of pregnant patients diagnosed on MOUD who received prenatal care and delivered at a single academic institution between January 2017 and July 2023. Subjects were divided into those who received prenatal anesthesia consultation and those who did not. Severe pain (numerical rating scale 0-10) was defined as score≥7. Statistical analysis was performed using Chi-square, Mann-Whitney U, and multivariable logistical regression tests with significance defined as p<0.05.

RESULTS

The cohort included 359 women on MOUD. Of these, 17.8 % (n=64) received anesthesia consultation and 82.2 % (n=295) did not. Factors found associated with receiving anesthesia consultation were prenatal care with an obstetric provider trained in maternal OUD (p<0.01), psychiatric diagnosis (p<0.01) and higher number of prenatal care visits (10.12 vs. 8.99, p=0.007). When comparing pain scores in the first 24 h postpartum, patients with prenatal anesthesia consultation had statistically significant lower rates of severe pain compared to those who did not (25 vs. 44.7 %, p=0.004). Anesthesia consultation (OR 0.34) and cesarean section (OR 2.81) were independent predictors of severe postpartum pain in the first 24 h after delivery.

CONCLUSIONS

Patients on MOUD who received antenatal anesthesia consultation report lower postpartum pain scores than those without consultation, which supports that multidisciplinary care for pregnant patients with OUD may help the postpartum experience.

Consensus Statement on Pain Management for Pregnant Patients with Opioid-Use Disorder from the Society for Obstetric Anesthesia and Perinatology, Society for Maternal-Fetal Medicine, and American Society of Regional Anesthesia and Pain Medicine

Pain management in pregnant and postpartum people with an opioid-use disorder (OUD) requires a balance between risks associated with opioid tolerance, including withdrawal or return to opioid use, considerations around social needs of the maternal-infant dyad, and the provision of adequate pain relief for the birth episode that is often characterized as the worst pain a person will experience in their lifetime. This multidisciplinary consensus statement between the Society for Obstetric Anesthesia and Perinatology (SOAP), Society for Maternal-Fetal Medicine (SMFM), and American Society of Regional Anesthesia and Pain Medicine (ASRA) provides a framework for pain management in obstetric patients with OUD. The purpose of this consensus statement is to provide practical and evidence-based recommendations and is targeted to health care providers in obstetrics and anesthesiology. The statement is focused on prenatal optimization of pain management, labor analgesia, and postvaginal delivery pain management, and postcesarean delivery pain management. Topics include a discussion of nonpharmacologic and pharmacologic options for pain management, medication management for OUD (eg, buprenorphine, methadone), considerations regarding urine drug testing, and other social aspects of care for maternal-infant dyads, as well as a review of current practices. The authors provide evidence-based recommendations to optimize pain management while reducing risks and complications associated with OUD in the peripartum period. Ultimately, this multidisciplinary consensus statement provides practical and concise clinical guidance to optimize pain management for people with OUD in the context of pregnancy to improve maternal and perinatal outcomes.

Endogenous opiates and behavior: 2023

This paper is the forty-sixth consecutive installment of the annual anthological review of research concerning the endogenous opioid system, summarizing articles published during 2023 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides and receptors as well as effects of opioid/opiate agonists and antagonists. The review is subdivided into the following specific topics: molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors (1), the roles of these opioid peptides and receptors in pain and analgesia in animals (2) and humans (3), opioid-sensitive and opioid-insensitive effects of nonopioid analgesics (4), opioid peptide and receptor involvement in tolerance and dependence (5), stress and social status (6), learning and memory (7), eating and drinking (8), drug and alcohol abuse (9), sexual activity and hormones, pregnancy, development and endocrinology (10), mental illness and mood (11), seizures and neurologic disorders (12), electrical-related activity and neurophysiology (13), general activity and locomotion (14), gastrointestinal, renal and hepatic functions (15), cardiovascular responses (16), respiration and thermoregulation (17), and immunological responses (18).

Persistent Postpartum Pain - A Somatic and Psychologic Perfect Storm

Persistent postpartum pain is common and has a complex etiology. It has both somatic and psychosocial provoking factors and has both functional and psychological ramifications following childbirth. Pain that limits the functional capacity of a person who has the daunting task to take care of all the demands of managing a growing newborn and infant can have debilitating consequences for several people simultaneously. We will review the incidence of persistent postpartum pain, analyze the risk factors, and discuss obstetric, anesthetic, and psychological tools for prevention and management. Based on the current knowledge, early antenatal screening and management is described as the most likely measure to identify patients at risk for persistent postpartum pain. Such antenatal management should be based on the close collaboration between obstetricians, anesthesiologists, and psychologists to tailor peripartum pain management and psychological support-based individual needs.
