Sleep disorders in physicians who perform shift work can result in increased risks of health problems that negatively impact performance and patient safety. Even those who cope well with shift work are likely to suffer from sleep disorders. The aim of this manuscript is to discuss possible causes, contributing factors and consequences of sleep disorders in physicians and to identify measures that can improve adaptation to shift work and treatment strategies for shift work-associated sleep disorders. ⋯ The home environment for daytime sleeping after a night shift should be very dark to allow endogenous melatonin secretion, which is a night signal and supports continuous sleep. Sleep disorders can be treated with timed light exposure, as well as behavioral and environmental strategies to compensate for sleep deprivation. Fatigue due to sleep deprivation can only be systematically treated with sleep.

Visualization and verification are key factors since the implementation of ultrasound-guided regional anesthesia. This article reviews and discusses newer technical innovations in regional anesthesia with regard to optimization of needle guidance, improvements in needle visibility, technical improvements in ultrasound techniques and innovative technologies in regional anesthesia. Clinically available applications are presented as well as experimental tools and techniques with a potential for clinical implementation in the future. ⋯ Compound imaging technology improves needle visibility in steep needle insertion angles and is already implemented in daily clinical practice. Sonoelastography improves tissue discrimination and detection of small amounts of fluids. Benefits of 3D and 4D ultrasound in regional anesthesia are discussed as well as experimental tools for tissue discrimination, such as optical reflection spectrophotometry.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by joint and systemic manifestations. As the prevalence in the adult population is approximately 1 %, anesthesia management in patients with RA has to be performed on a regular basis. ⋯ Furthermore, possible complications should be considered in patients with chronic medication, particularly in patients treated with immunomodulating drugs. Therefore, a careful preoperative evaluation, preparation for possible difficult airway management and a selective anesthesia management in patients with RA can prevent possible complications.

Peripheral nerve catheters (PNC) play an important role in postoperative pain treatment following major extremity surgery. There are several trials reported in the literature which investigated the efficacy and safety of ultrasound (US) and nerve stimulator (NS) guided PNC placement; however, most of these trials were only small and focused mainly on anesthesiologist-related indicators of block success (e.g. block onset time and procedure time) but not primarily on patient-related outcome data including postoperative pain during movement. ⋯ This database analysis demonstrated that patients treated with US-guided PNC reported significantly lower postoperative pain scores and the number of patients requiring additional opioids was significantly lower on the day of surgery. The numbers of multiple punctures and failed catheter placements were reduced in the US group, which might be seen as an advantage of US-guided regional anaesthesia.

The anesthesia premedication consultation is an obligatory procedure prior to any upcoming surgery. It is the anesthesiologist's responsibility to collect all necessary information regarding the patient's medical condition to decide on the appropriate narcosis and to ensure that the patient comprehends the anesthesia procedure and its effects. ⋯ The QPL-A is a useful tool for meeting the subjective information needs of patients which could improve the patient orientation of the anesthesia premedication consultation.
