HELLP syndrome (hemolysis, elevated liver enzymes and low platelets) complicates 0.5-0.9% of pregnancies and is frequently associated with multiorgan dysfunction. Treatment relies on prompt diagnosis, delivery and supportive care. The clinical presentation may make the concurrent diagnosis and management of other disease entities challenging. This case report describes a patient with postpartum HELLP syndrome complicated by severe multiorgan dysfunction and pulmonary embolism.

Emergent transesophageal echocardiography in hemodynamically unstable obstetric patients.
The obstetric population has an increasing incidence of comorbid conditions. These, coupled with the possibility of acute embolic events involving air, amniotic fluid, and thrombus, increase the likelihood of hemodynamic instability. Although the utility of transesophageal echocardiography to guide management in cardiac and high-risk, non-cardiac surgical populations has been well established, the emergent use in critically-ill parturients has not been comprehensively evaluated. ⋯ Severe hemodynamic instability and cardiac arrest can occur in previously healthy parturients in pregnancy. Our data suggest that emergent transesophageal echocardiography is a valuable tool in determining the etiology and directing therapy of refractory hypotension or cardiac arrest in obstetric patients.

Differences between anticipated and perceived difficulty and insertion duration of labor epidural techniques among anesthesiologists, nurses and patients.
Difficulty with the labor epidural technique has been described using a variety of criteria, but remains inadequately defined. We sought to determine the reasons cited for difficulty with the insertion of labor epidural techniques among anesthesiologists, nurses, and patients. We hypothesized that the perception of procedural difficulty would correlate among participants and with the elapsed duration of the insertion attempt. ⋯ Difficulty with the epidural technique is associated with anticipated difficulty and procedural duration. The reasons for perceived difficulty differ among anesthesiologists, nurses and obstetric patients, with patients most commonly citing pain experienced.

Haemorrhage is one of the commonest causes of maternal critical care admission. Cell salvage used during caesarean section can contribute to a reduction in allogeneic blood consumption. This study sought to provide a practical method to salvage blood lost after vaginal delivery and a description of the constituents before and after washing. ⋯ Vaginal blood can be collected efficiently with little disruption to patient management. The amounts of haemolysis and washout of non-red cell blood components are consistent with results in our cell salvage quality assurance programme for caesarean section and non-obstetric surgery. Although bacteria are detectable in all the post-wash and post-filter samples, the median residual contamination is similar to that found with cell salvage in caesarean section, and if re-infused would result in a circulating bacteraemia of <1 cfu/mL; this is similar to that seen with dental procedures (0.3-4.0 cfu/mL) and is thought to be clinically insignificant.
