Review
[General principles of sonography, part 2 : System technology, basic techniques and artifacts].
Since the introduction of portable ultrasound systems, sonography has become well established as an integral part of the anesthesiological and critical care equipment and of monitoring. The selection of various ultrasound transducers, sonographic techniques and imaging modes enables a broad variety of clinical applications. In depth background knowledge of the technical aspects is crucial for obtaining what a highly sophisticated ultrasound system has to offer, i.e., sonographic transparency of the complete body and valid information on the structure and dynamics of organs and the circulation.

[Completely subcutaneous implantable cardioverter defibrillator : Care of S-ICD® wearers during childbirth].
Inappropriate shock delivery is a problem that has been described for subcutaneous implantable cardioverter defibrillators (S-ICDs). Situations which predispose inappropriate shock delivery, such as childbirth, must be identified and the best treatment strategies selected. Inactivation of the S-ICD is the safest approach to avoiding inappropriate shock delivery. Inactivation of the S-ICD requires adequate patient monitoring and facilities for manual shock delivery.

The quality assurance of care and patient safety, with increasing cost pressure and performance levels is of major importance in the high-risk and high cost area of the operating room (OR). Standard operating procedures (SOP) are an established tool for structuring and standardization of the clinical treatment pathways and show multiple benefits for quality assurance and process optimization. ⋯ The SOP management system SOPHIA combines the benefits of the forerunner version Aesculapp with improved options for intradepartmental maintenance and administration of the SOPs and the possibility of an export and editing function for interinstitutional exchange of SOPs.

Noble gases are chemically inert elements, some of which exert biological activity. Experimental neuroprotection in particular has been widely shown for xenon, argon and helium. ⋯ Besides an interference with neuronal ion-gated channels and cellular signaling pathways as well as anti-apoptotic effects, the modulation of neuroinflammation seems to play a crucial role. This review presents the current knowledge on neuroprotection by noble gases with a focus on interactions with the neuronal-glial network and neuroinflammation and the perspectives on clinical applications.
