Gerard W. Ostheimer Lecture: What's New in Obstetric Anesthesia 2018

This article summarizes the Gerard W. Ostheimer Lecture given at the 2019 Society for Obstetric Anesthesia and Perinatology annual meeting. The article summarizes key articles published in 2018 that were presented in the 2019 Ostheimer Lecture, with a focus on maternal mortality, maternal complications, analgesic and anesthetic management of vaginal and cesarean deliveries, postpartum care, and the impact of anesthesia on maternal outcomes. The reviewed literature highlights many opportunities for anesthesiologists to impact maternal care and outcomes. The major themes presented in this manuscript are maternal mortality including amniotic fluid and cardiac arrest; postpartum hemorrhage; venous thromboembolism; management of spinal-induced hypotension; postpartum care including opioid use, postcesarean analgesia, and postpartum depression. A proposed list of action items and research topics based on the literature from 2018 is also presented. Specifically, anesthesiologists should use prophylactic vasopressor infusions during elective cesarean delivery; use a structured algorithm to diagnose pulmonary embolus, and reevaluate the use of D-dimer measurements; target postpartum opioid analgesia and prescribing; use multimodal postcesarean delivery analgesia, preferably with neuraxial hydrophilic opioids; and study any association between labor analgesia on postpartum depression.
