ReviewPeripartum management of cardiac arrhythmias: a narrative review.
Cardiac arrhythmias are responsible for a significant portion of cardiovascular disease among pregnant people. As the incidence of arrhythmias in pregnancy continues to increase, anesthesiologists who care for obstetric patients should be experts managing arrhythmias in pregnancy. ⋯ Peripartum monitoring and labor analgesia recommendations are discussed. Additionally, management of cardioversion, management of pacemakers and implantable cardioverter-defibrillators, and advanced cardiac life support in the setting of pregnancy is reviewed.

ReviewExtracorporeal membrane oxygenation (ECMO) in pregnancy and peripartum: a focused review.
As the medical complexity of pregnant patients increases, the rate of maternal morbidity has risen. Maternal cardiovascular disease is a leading cause of maternal morbidity and mortality followed closely by sepsis and infection, both of which may be associated with respiratory failure. ⋯ Obstetricians and anesthesiologists who care for women on the labor floor must strive to recognize at-risk and deteriorating patients, facilitate escalation of care when appropriate, and engage consultant teams to consider the need for extracorporeal support in high-risk circumstances. This article reviews the epidemiology, indications, specific considerations, potential complications, and outcomes of extracorporeal life support in pregnant and peripartum patients.

ReviewAnaesthetic management of obstetric patients with Chiari type I malformation: a retrospective case series and literature review.
The peripartum management of obstetric patients with Chiari type I malformation remains a challenge due to the degree of cerebellar tonsillar herniation and a paucity of published evidence. There is concern about neuraxial anaesthetic blocks and uncertainty regarding the optimum mode of delivery. We systematically searched the literature for the obstetric management of patients with Chiari type I malformation, independent of publication date and language. ⋯ Our review reveals the use of a variety of modes of delivery and anaesthetic techniques and that most patients suffered no neurological complication. We conclude there is no of evidence to avoid any one approach to labour analgesia, delivery and anaesthesia. We propose a holistic, individualised and patient-centred approach with an appraisal of the risks and benefits to support shared-decision making.

Randomized Controlled TrialPre-oxygenation using high flow humidified nasal oxygen or face mask oxygen in pregnant people - a prospective randomised controlled crossover non-inferiority study (The HINOP2 study).
Airway guidelines recommend pre-oxygenation of obstetric patients to an end tidal oxygen concentration (etO2) ≥90%. High flow nasal oxygen (HFNO) achieves this in 60% of pregnant people. However face mask (FM) pre-oxygenation also may not achieve this target in all patients. In this study we determined whether HFNO pre-oxygenation is non-inferior to FM pre-oxygenation. ⋯ In this cohort of pregnant people at term in a simulated environment, pre-oxygenation with HFNO was not inferior to FM pre-oxygenation. FM pre-oxygenation did not achieve pre-oxygenation targets in over 50% of participants.

Randomized Controlled Trial Comparative StudyComparison of erector spinae plane and transversus abdominis plane block for postoperative analgesia after caesarean delivery under spinal anaesthesia: A randomised controlled trial.
Truncal blocks contribute to multimodal analgesia that enhances early recovery after caesarean delivery. The transversus abdominis plane (TAP) block is an established technique that offers somatic abdominal wall analgesia. The erector spinae plane (ESP) block is a fascial plane technique that may offer additional visceral analgesic effects. This study hypothesized that ESP block would offer superior analgesic efficacy to TAP block in women undergoing caesarean delivery under spinal anaesthesia. ⋯ This study found similar postoperative opioid use and analgesic efficacy between ESP and TAP block after caesarean delivery performed under spinal anaesthesia.
