Case ReportsPeripartum management of a parturient with type 1C (clearance) von Willebrand disease.
Peripartum replacement of factor VIII and von Willebrand factor is not usually required in type 1 von Willebrand disease, as the levels of endogenous factors tend to increase to within the normal range as a physiological change of pregnancy. However, there is wide heterogeneity of genotypes and phenotypes associated with type 1 von Willebrand disease. Here, we describe the anesthetic management of a parturient with type 1C von Willebrand disease, a subtype characterized by decreased plasma von Willebrand factor survival.

Randomized Controlled Trial Multicenter StudyA risk score for postoperative nausea and/or vomiting in women undergoing cesarean delivery with intrathecal morphine.
Postoperative nausea and/or vomiting affects up to 80% of parturients undergoing cesarean delivery, but there is a lack of obstetric-specific risk-prediction models. We performed this study to identify postoperative nausea/vomiting risk factors in parturients undergoing cesarean delivery, formulate an obstetric-specific prediction model (Duke score), and compare its performance against the Apfel score. ⋯ Both Duke and Apfel scores exhibited similar but poor predictive performance. Until better tools are developed, routine prophylactic anti-emetics appears to be a reasonable approach in this patient population.

Observational StudyThe crossed-leg position increases the dimensions within the acoustic target window for neuraxial needle placement in term pregnancy: a prospective observational study.
Neuraxial anesthesia in obstetric patients may be difficult to achieve due to anatomical changes in pregnancy. The crossed-leg position may help in optimizing patient position. We prospectively evaluated the utility of the crossed-leg position compared with a standard position using ultrasound measurements. ⋯ We demonstrated a significant increase in the sonographically measured lengths of the posterior longitudinal ligament, ligamentum flavum and interlaminar distance in the crossed-leg position when compared with the standard position. Both positions were comfortable. Further studies should explore whether these findings translate clinically into easier needle placement in the crossed-leg position.

Case ReportsCongenital complete heart block in the setting of severe pre-eclampsia requiring urgent Cesarean section.
Congenital complete heart block is a rare phenomenon that may be discovered during pregnancy in patients who were previously asymptomatic. Peripartum management of these patients mandates a multidisciplinary approach with careful planning regarding indications for pacing, appropriate anesthetic technique, and contingency planning. Approaches to anesthetic management for congenital complete heart block have been described, but management in association with severe pre-eclampsia has not been reported. We describe the anesthetic management of a parturient with complete heart block who presented with severe pre-eclampsia requiring urgent cesarean section.
