[Optimization of blood gas analysis in intensive care units : Reduction of preanalytical errors and improvement of workflow].
Point of care testing with blood gas analysis (BGA) is an important factor for intensive care medicine. Continuous efforts to optimize workflow, improve safety for the staff and avoid preanalytical mistakes are important and should reflect quality management standards. ⋯ The implementation of a new BGA system with labeled syringes and automated processing of the specimens was possible without any difficulties under daily clinical routine conditions in this 10-bed intensive care unit (ICU). A gain of time could not be measured but a reduction in preanalytical errors using the labeled syringes with automated processing was found. Delayed analysis of blood samples can lead to significant changes in pO2 and pCO2 depending on the type of syringe used.

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.

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.

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.
