During the perioperative and postoperative care of pregnant women it is prudent to pay close attention to the changed physiology of these patients. The main principles of care are the preservation of maternal and fetal homeostasis as well as avoidance of any substances with toxic effects on the fetus. In order to provide pregnant patients with good quality care, all relevant disciplines should be involved as early as possible. ⋯ If possible anticonvulsives should not be used as an adjunct in pain management during pregnancy. The use of thoroughly investigated antidepressants seems to be a better alternative. Apart from drug therapy it is important to use all available conservative pain treatment options.

Due to a huge increase in the implantation of ventricular assist devices (VAD) over the last few years and the enormous technical advances in functional safety, a growing number of patients with VAD are discharged from hospital, who are still considered to be severely ill. This results in an increased probability of these patients interacting with emergency services where personnel are unaware of the presence of a VAD, creating anxiety and uncertainty regarding how to treat these patients. This article presents an overview of the most common problems and pitfalls regarding VADs. It also presents an algorithm for dealing with emergencies involving these patients including the diagnostics, treatment and primary transport.

An acute obstruction of blood flow in central vessels of the systemic or pulmonary circulation causes the clinical symptoms of shock accompanied by disturbances of consciousness, centralization, oliguria, hypotension and tachycardia. In the case of an acute pulmonary embolism an intravascular occlusion results in an acute increase of the right ventricular afterload. ⋯ The high dynamics of this potentially life-threatening condition is a hallmark of all types of obstructive shock. This requires an expeditious and purposeful diagnosis and a rapid and well-aimed therapy.

Comparative Study
[Ketamine as anesthetic agent in electroconvulsion therapy].
Electroconvulsive therapy (ECT) is a well-established, safe and effective treatment for severe psychiatric disorders. Ketamine is known as a core medication in anesthesiology and has recently gained interest in ECT practice as there are three potential advantages: (1) ketamine has no anticonvulsive actions, (2) according to recent studies ketamine could possess a unique intrinsic antidepressive potential and (3) ketamine may exhibit neuroprotective properties, which again might reduce the risk of cognitive side effects associated with ECT. ⋯ A repeated measurement multiple logistic regression analysis revealed significant advantages in the ketamine group for seizure concordance and postictal suppression (both are surrogates for central inhibition). S-ketamin also necessitated the use of a higher dose of urapidil and a higher maximum postictal heart frequency. Clinically relevant psychiatric side effects were rare in both groups. No psychiatric side effects occurred in the subgroup of patients with schizophrenia (ketamine: n = 30). The mean dose of S-ketamine used increased in the first years but stabilized at 63 mg per patient in 2014. From these experiences it can be concluded that S-ketamine can be recommended at least as a safe alternative to barbiturates.

The current report highlights the use of venoarterial extracorporeal membrane oxygenation (va-ECMO) in a case of pulmonary embolism complicated by right ventricular failure. A 38-year-old woman was admitted to a secondary care hospital with dyspnea and systemic hypotension. Diagnostic testing revealed a massive pulmonary embolism. ⋯ To allow the necessary transport of the highly unstable patient to a tertiary care center a mobile ECMO team was called in. The team immediately initiated awake va-ECMO as a bridge to therapy. Extracorporeal support subsequently allowed a safe transportation and successful completion of the surgical procedure with complete recovery.
