Golden Hour Management in Obstetric Emergencies

Maternal Stabilization and Cardiac Arrest Management

The American College of Obstetricians and Gynecologists recommends initiating standard ACLS protocols immediately upon cardiac arrest, with continuous left uterine displacement to relieve aortocaval compression, and beginning hysterotomy if maternal circulation is not restored within 4 minutes of arrest, to improve maternal and fetal outcomes 1
The American Heart Association suggests that circulation must be restored within 4 minutes before proceeding to perimortem cesarean delivery, with a focus on the "4-minute rule" to minimize delays in treatment 1

The World Health Organization recommends administering 5-10 IU of oxytocin via slow IV or intramuscular injection at the time of shoulder release or immediately postpartum to reduce hemorrhage incidence, with a focus on prevention in all deliveries, including those occurring outside specialized maternity facilities 2
The American College of Obstetricians and Gynecologists suggests administering 1 gram of tranexamic acid intravenously within 1-3 hours of bleeding onset to reduce maternal mortality, with a number needed to treat of 276, as demonstrated by the WOMAN trial 2

The Society for Obstetric Anesthesia and Perinatology recommends using a cognitive aid checklist for AFE management, focusing on the "ABC" principle: airway, breathing, and circulation support, with a concise and immediately accessible checklist in the labor and delivery unit 3

The American College of Obstetricians and Gynecologists suggests systematically assessing multiparity, history of previous rapid or non-hospital delivery, regular painful uterine contractions, and urge to push when evaluating for imminent delivery, with a focus on predictive clinical signs 4
The American Academy of Pediatrics recommends performing cervical examination before contacting the receiving obstetric team to optimize patient triage, with a focus on pre-hospital management and rapid positioning for the McRoberts maneuver 4

The American College of Obstetricians and Gynecologists recommends coordinating immediately with emergency services to discuss antihypertensive treatment and magnesium sulfate administration, with a focus on strict fluid balance and clear documentation 5

The American Society of Anesthesiologists suggests inserting a neuraxial catheter early for anticipated difficult deliveries or obstructed labor, with a focus on avoiding general anesthesia during a crisis, and using dilute concentrations of local anesthetics with opioids to produce minimal motor block 1, 6
The American Society of Anesthesiologists recommends administering non-particulate antacids, H₂ receptor antagonists, and/or metoclopramide before all surgical procedures, with a focus on aspiration prophylaxis and clear liquids up to 2 hours before anesthesia induction 1

The American College of Obstetricians and Gynecologists suggests assessing for cephalopelvic disproportion before proceeding with augmentation, which occurs in 25-30% of active phase arrest cases, with a focus on initial assessment and oxytocin augmentation as first-line treatment 6
The American College of Obstetricians and Gynecologists recommends considering reverse breech extraction for impacted fetal head during cesarean delivery, which may be associated with improved Apgar scores and reduced NICU admissions 6

The American College of Obstetricians and Gynecologists recommends establishing direct contact between the on-call obstetrician and emergency medical services team for all potential obstetric emergencies, with a focus on clear communication and documentation, and immediate evaluation and systematic obstetrical examination for patients reporting imminent delivery or severe pre-eclampsia symptoms 5
