BACKGROUND: Compared to standard labor epidurals, placement of a dural puncture epidural (DPE) has been shown to improve labor analgesia efficacy, speed onset of analgesia, and decrease failure rates. However, there is a concern of increased post-dural puncture headache (PDPH) risk. A 25-gauge or larger spinal needle is typically needed for a DPE to have improved efficacy over a standard epidural. A prior meta-analysis comparing combined spinal-epidurals (CSEs) with epidurals did not identify a difference in PDPH rates, but many of the included randomized controlled trials (RCTs) used smaller diameter (27–29 gauge) spinal needles. This systematic review and meta-analysis of RCTs evaluates headache frequency following CSE or DPE labor analgesia techniques with 24- or 25-gauge spinal needles. METHODS: Medline, EMBASE, Scopus, Database of Abstracts of Reviews of Effects, Web of Science Core Collection, and Cochrane databases were searched on May 7, 2024, for RCTs comparing either DPE or CSE techniques using 24- or 25-gauge spinal needles with epidural labor analgesia. The primary outcome was headache. The risk-of-bias 2 tool was used to assess bias. The odds ratio (OR) was the chosen effect size using binomial family Bayesian estimation. The reference category for estimation was the conventional epidural technique group. RESULTS: Encompassing 3278 patients, 1765 (53.8%) received labor epidurals, 971 (29.6%) received DPEs, and 542 (16.5%) received CSEs. The rate of headaches in both groups was low, with headache rates of CSE/DPE and epidural groups (0.59% vs 0.34%), respectively. Headache was a secondary outcome in all the RCTs. In 10 of the 16 RCTs (62.5%), no patients of 1428 (0%; 95% credible interval [CI], 0.00–0.25) reported a headache. A total of nine (0.6%) headaches were reported in the DPE/CSE patients (denominator 1513) and six (0.3%) headaches were reported in the traditional epidural patients (denominator 1765). The posterior distribution of the treatment effect ( θ ) showed that the log OR of 0.35 favored the control group as having fewer events, but the number of events was rare, and the 95% CI was wide (−0.49 to 1.22). CONCLUSIONS: Headache was a rare event in both groups. Although these results are reassuring that either technique is clinically safe, they should be interpreted cautiously. A large RCT examining PDPH as the primary outcome with long-term follow-up is needed to more precisely determine if placement of a DPE or CSE with a 24- or 25-gauge spinal needle increases the risk of PDPH.

Purpose of review Medication administration errors represent a significant yet preventable cause of patient harm in the peripartum period. Implementation of best practices contained in this manuscript can significantly reduce medication errors and associated patient harm. Recent findings Cases of medication errors involving unintended intrathecal administration of tranexamic acid highlight the need to improve medication safety in peripartum patients and obstetric anesthesia. Summary In obstetric anesthesia, medication errors can include wrong medication, dose, route, time, patient, or infusion setting. These errors are often underreported, have the potential to be catastrophic, and most can be prevented. Implementation of various types of best practice cost effective mitigation strategies include recommendations to improve drug labeling, optimize storage, determine correct medication prior to administration, use non-Luer epidural and intravenous connection ports, follow patient monitoring guidelines, use smart pumps and protocols for all infusions, disseminate medication safety educational material, and optimize staffing models. Vigilance in patient care and implementation of improved patient safety measures are urgently needed to decrease harm to mothers and newborns worldwide.

We report the case of a term neonate who was somnolent at birth with ventilatory distress and experienced 2 seizures shortly after delivery. Laboratory tests revealed the neonate had a serum sodium of 113 mmol/L. The seizures stopped after treatment with midazolam, and the sodium was corrected slowly with 3% hypertonic saline without further sequelae. The severe neonatal hyponatremia and seizures were attributed to maternal consumption of excessive amounts of coconut water during labor. This case demonstrates the importance of careful consideration of both fluid volume and fluid electrolyte composition during labor to prevent adverse maternal and neonatal outcomes.

AbstractA wide range of fetal interventions are being performed worldwide to save the fetus's life, prevent permanent fetal organ damage, and allow a successful transition to extrauterine life. However, these are invasive procedures and can be associated with serious complications. This article focuses on promoting a culture of safety by highlighting five common error traps while anesthetizing patients for fetal interventions. They include failure to preserve uteroplacental perfusion and gas exchange, failure to achieve adequate uterine relaxation prior to hysterotomy, failure to monitor the fetus and prepare for fetal/neonatal resuscitation, failure to prepare for maternal hemorrhage, and failure to promptly treat uterine atony. Practical tips for avoiding these serious complications will also be discussed.

Maternal–fetal surgery is a rapidly evolving specialty, and significant progress has been made over the last 3 decades. A wide range of maternal–fetal interventions are being performed at different stages of pregnancy across multiple fetal therapy centers worldwide, and the anesthetic technique has evolved over the years. The American Society of Anesthesiologists (ASA) recognizes the important role of the anesthesiologist in the multidisciplinary approach to these maternal–fetal interventions and convened a collaborative workgroup with representatives from the ASA Committees of Obstetric and Pediatric Anesthesia and the Board of Directors of the North American Fetal Therapy Network. This consensus statement describes the comprehensive preoperative evaluation, intraoperative anesthetic management, and postoperative care for the different types of maternal–fetal interventions.
