Randomized Controlled Trial Comparative StudyP6 acupressure versus sham acupressure for prevention of intraoperative nausea and vomiting during cesarean delivery under neuraxial anesthesia: a randomized controlled trial.
Intraoperative and postoperative nausea and vomiting (IONV and PONV) are common during cesarean delivery (CD) with neuraxial anesthesia. Limited information exists on the antiemetic benefit of combined P6 acupoint stimulation with acupressure (P6 acupressure) and pharmacologic antiemetics on preventing IONV and PONV after CD. This study assessed the antiemetic efficacy of P6 acupressure compared to a non-P6 acupoint stimulation with acupressure (sham acupressure) in preventing IONV during CD. ⋯ P6 acupressure did not reduce the incidence of IONV or PONV when combined with antiemetic therapy per enhanced recovery recommendations. There does not appear to be sufficient evidence to support using P6 acupressure for IONV prevention.

ReviewAnaesthesia considerations for assisted reproductive technology: a focused review.
The global burden of infertility is significant and the evidence suggests it is increasing in prevalence worldwide. Assisted reproductive technologies (ARTs) are fertility related treatments used to achieve pregnancy which involve the manipulation of both oocytes and sperm. The specialty is rapidly growing and anaesthesia may be required for several stages in the ART cycle. ⋯ In this review article we explain the key steps of the ART cycle and the role of anaesthesiologists in this process. We also highlight key patient considerations, the implications of remote site anaesthesia and the safety concerns with provision of sedation by non-anaesthesiologists. Finally we outline a typical anaesthetic technique used in our institution for transvaginal oocyte retrieval.

ReviewObstetric anesthesia considerations in pregnancy-associated myocardial infarction: a focused review.
Pregnancy-associated myocardial infarction (PAMI) is a rare but serious complication that can occur either during pregnancy or postpartum. The etiologies of PAMI are atherosclerosis, spontaneous coronary artery dissection, coronary thrombosis, coronary embolism, and coronary vasospasm. ⋯ Anesthetic management during delivery in patients with PAMI should consist of early and carefully titrated neuraxial analgesia and anesthesia, maintenance of normal sinus rhythm, preservation of afterload, and monitoring for and avoiding myocardial ischemia. To improve the care of women with PAMI, a multidisciplinary team of cardiologists, maternal fetal medicine specialists, obstetric providers, neonatologists, and anesthesiologists must work collectively to manage these complex patients.

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.

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.
