Review
[Autonomy and welfare in intensive care medicine : Practical approach in difficult situations].
In intensive care units far-reaching decisions are often made at short notice that require the consent of the informed patient. If this is not possible due to the patient's condition, physicians and legal representatives must ascertain the previously expressed or presumed will of the patient and act accordingly. The legal principles are specified in the Patient Advance Directives Act and the Patient Rights Act. ⋯ To avoid conflicts between patient autonomy and medical treatment, the aims of therapy must be regularly discussed with the patient, representatives or relatives and documented in a written form. Checklists can be useful for structured consultations, to promote transparency and to avoid misunderstandings. Ethics consultations can help to deescalate critical situations.

Unilateral spinal anesthesia is a cost-effective and rapidly performed anesthetic technique. An exclusively unilateral block only affects the sensory, motor and sympathetic functions on one side of the body and offers the advantages of a spinal block without the typical adverse side effects seen with a bilateral block. The lack of hypotension, in particular, makes unilateral spinal anesthesia suitable for patients with cardiovascular risk factors e. g. aortic valve stenosis or coronary artery disease. ⋯ An injection of 5 mg (1 ml) hyperbaric bupivacaine 0.5 % provides an hour-long block to T 12, and a dose of 7.5 to 10 mg (1.5-2.0 ml) extends the block to T 6. Adding clonidine (0.5 to 1.0 µg/kg BW) to the injection prolongs the duration of the block to approximately two to three hours. During the 20-minute fixation period, the cephalad spread of the block can be influenced to a certain extent by raising or lowering the head of the table.

Randomized Controlled Trial
[Simulation-based training and OR apprenticeship for medical students : A prospective, randomized, single-blind study of clinical skills].
Simulation-based training (SBT) has developed into an established method of medical training. Studies focusing on the education of medical students have used simulation as an evaluation tool for defined skills. A small number of studies provide evidence that SBT improves medical students' skills in the clinical setting. Moreover, they were strictly limited to a few areas, such as the diagnosis of heart murmurs or the correct application of cricoid pressure. Other studies could not prove adequate transferability from the skills gained in SBT to the patient site. Whether SBT has an effect on medical students' skills in anesthesiology in the clinical setting is controversial. To explore this issue, we designed a prospective, randomized, single-blind trial that was integrated into the undergraduate anesthesiology curriculum of our department during the second year of the clinical phase of medical school. ⋯ With the methods applied, this study could not prove that 225 min of SBT before the operating room apprenticeship increased the medical students' clinical skills as evaluated in the operating room. Secondary endpoints indicate that medical students have better clinical skills at the end of the entire curriculum when they have been trained through SBT before the operating room apprenticeship. However, the authors believe that simulator training has a positive impact on students' acquisition of procedural and patient safety skills, even if the methods applied in this study may not mirror this aspect sufficiently.

In addition to assessing stress-coping strategies in patients, equal attention should be paid to health-care professionals. The literature on the stress-coping strategies of emergency physicians - health-care professionals who are frequently subject to stress in a fast-paced clinical setting - is scant. Therefore, we aimed to investigate the stress-coping strategies of emergency-care physicians (ECPs) in Germany. ⋯ ECPs experience stress in the same manner as patients and other professionals, and they must address and cope with stress appropriately. For future research, studies with a longitudinal approach to monitor the underlying mechanisms are suggested. For clinical practice and policy-making, structural changes in work patterns and psychological support should be considered, which may be of particular benefit for female ECPs.
