ReviewWhat's new in obstetric anesthesia: the 2011 Gerard W. Ostheimer lecture.
The Gerard W. Ostheimer lecture is delivered at the Society for Obstetric Anesthesia and Perinatology Annual Meeting. The lecture provides a comprehensive review of the previous year's literature in obstetric anesthesia, obstetrics, perinatology, and health services research relevant for obstetric anesthesiologists. This article covers several of the major themes that emerged from the 2010 literature.

Case ReportsAnesthetic management of vaginal delivery in a parturient with hemochromatosis induced end-organ failure.
The vast majority of females affected by hemochromatosis are asymptomatic during childbearing years. We were able to provide effective obstetric anesthesia care to a 35-year-old woman with severe hemochromatosis. She had systolic heart failure with a left ventricular ejection fraction of 15%, severe pulmonary hypertension, mitral insufficiency, a history of ventricular tachycardia, cirrhosis, obstructive sleep apnea, gestational diabetes, and severe scoliosis. ⋯ An arterial line and epidural analgesic were placed before induction of labor. Vaginal delivery was accomplished with passive decent of the fetus and forceps assistance. We discuss hemochromatosis and its implications for the parturient.

Case ReportsPerioperative management of a parturient with hyponatraemia due to carbamazepine therapy.
We describe the perioperative management of an epileptic parturient who developed hyponatraemia due to carbamazepine therapy. Caesarean delivery was performed under combined spinal-epidural anaesthesia with a good outcome for both mother and neonate. The diagnostic and therapeutic approach, anaesthetic implications and maternal and neonatal risks for a patient with hyponatraemia complicating carbamazepine therapy are discussed.

Case ReportsPeripartum management of two parturients with ornithine transcarbamylase deficiency.
Ornithine transcarbamylase deficiency is a rare X-linked disorder in which female carriers are usually heterozygous for the ornithine transcarbamylase deficiency gene. In pregnancy it has been associated with altered mental status, seizures, coma and death, especially in the postpartum period. ⋯ Neuraxial techniques were used for pain relief in labor and anesthesia for operative delivery. A dextrose infusion provided caloric intake during labor and perioperatively.

Effect of μ-opioid receptor A118G polymorphism on the ED50 of epidural sufentanil for labor analgesia.
A common polymorphism of the μ-opioid receptor gene (OPRM1, p.118A/G), which has been shown to effect the response to neuraxial opioids, occurs in 30% of Caucasian women. This double-blind up-down sequential allocation study was designed to examine the effect of p.118A/G on the ED50 of epidural sufentanil for labor analgesia. ⋯ Women carrying the variant allele of p.118A/G of OPRM1 (G118) had a lower ED50 for epidural sufentanil given for early labor analgesia than women homozygous for the wild-type allele.
