Review"This is how we do it" Maternal and fetal anesthetic management for fetoscopic myelomeningocele repairs: the Texas Children's Fetal Center protocol.
Prenatal repair of myelomeningocele (MMC) is associated with lower rates of hydrocephalus requiring ventriculoperitoneal shunt and improved motor function when compared with postnatal repair. Efforts aiming to develop less invasive surgical techniques to decrease the risk for the pregnant patient while achieving similar benefits for the fetus have led to the implementation of fetoscopic surgical techniques. While no ideal anesthetic technique for fetoscopic MMC repair has been demonstrated, we present our anesthetic approach for these repairs, including considerations for both the pregnant patient and the fetus. ⋯ Additional considerations for the fetus include monitoring, fetal resuscitation strategies, and the theoretical risk of anesthetic neurotoxicity. Postoperatively, we use a multi-modal, opioid sparing regimen for analgesia. As advances in fetal surgery aiming to minimize risk to the pregnant patient alter the surgical approach, maternal-fetal anesthesiologists must adapt and incorporate the unique considerations of fetoscopy into their anesthetic management.

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.

ReviewObstetric anesthesia management of dilated cardiomyopathies and heart failure: a narrative review.
Pregnancy in patients with dilated cardiomyopathy carries a significantly increased risk of maternal mortality or severe morbidity, and pregnancy is typically considered contraindicated for patients with severely reduced ventricular function. Nonetheless, anesthesiologists will still encounter patients with cardiomyopathy requiring delivery or termination care. ⋯ Vaginal delivery, with effective neuraxial anesthesia is the preferred mode of delivery in most patients with cardiomyopathy, with cesarean delivery reserved for maternal or fetal indications. The Pregnancy Heart Team is vital in coordinating the multidisciplinary care necessary to safely support these patients through pregnancy.

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.
