The implementation of diagnosis-related groups (DRGs) sharply increased economic pressure on hospitals. Hence, process optimization was focussed on cost-intensive areas, namely the operation room (OR) departments. Work-flow in the OR is characterized by a mandatory interlocking of the job functions of many different occupational groups and the availability of a variety of different materials. ⋯ Hence, in a German university hospital the Department of Hospital Sterile Supplies was integrated into the OR management of the Department of Anesthesiology. This led to a close coordination of work-flow processes, and concomitantly a significant reduction of production costs of sterile supplies could be achieved by direct interaction with the OR. Thus, hospital sterile supplies can reasonably be integrated into an OR management representing a new interesting business area for OR organization.

Dysregulation of the intracellular calcium concentration is thought to play a key role in the so-called ischemic cascade, as well as for the development of cerebral vasospasm after subarachnoid haemorrhaging (SAH). Therefore, the prophylactic/therapeutic administration of cerebral calcium channel blockers for neurosurgical patients appears to be a compelling idea to prevent ischemic complications. There are abundant data on the efficacy of cerebral calcium antagonists in various animal models of central nervous system pathologies, however, very little clinical evidence exists to justify their use in humans in respective situations. ⋯ Experimental results suggest that blockers of other calcium channel subtypes may be promising for future clinical roles in primary or secondary ischemic brain injury. However, it is also possible that calcium-independent mechanisms play a more important role during the development of the ischemic damage than previously assumed. Currently, there is no clinical evidence to support the prophylactic use of calcium antagonists to prevent ischemic complications in neurosurgical patients without SAH.

Review Meta Analysis
[Perioperative pharmacological myocardial protection. Systematic literature-based process optimization].
Patients with major cardiac risk factors have been suggested to benefit from perioperative beta-blockade. However, the scientific literature on perioperative beta-blockade needs to be interpreted carefully. So far treatment recommendations for millions of patients are based on heterogeneous data from randomized trials with divergent study results. ⋯ Thus, dose adjustments, safety aspects, and monitoring of beta-blocker therapy seem to be mandatory. So far evidence from relevant trials about how to best implement perioperative beta-blockade is lacking. This article offers a simple clinical concept for this purpose.

The perivascular axillary plexus block is an easily applicable procedure with a low risk of complications but with a high failure rate. To improve this, the standard procedure was combined with transpectoral sonography to benefit from the advantages of ultrasound, while using a nearly unchanged puncture technique. ⋯ The rate of complete blocks without the use of transpectoral sonography in our clinic and in the literature was approximately 72%, whereas using transpectoral ultrasound it was 96.5%. None of the 86 patients with transpectoral sonography required general anaesthesia. The onset time using transpectoral sonography was approximately 6 min. The perivascular axillary plexus block, combined with transpectoral sonography, is an effective and efficient procedure.

Based on the 2005 International Consensus Conference on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science with Treatment Recommendations of the International Liaison Committee on Resuscitation (ILCOR), guidelines were published for managing basic and advanced life-saving procedures in the event of cardiac arrest. The fact that special circumstances for cardiac arrest must be considered resulted in a separate chapter. This two-part article reviews essential information as well as necessary modifications of the standard advanced life support algorithm in cases of electrolyte disorders, hyperthermia and hypothermia, cardiac arrest in pregnancy, trauma, electrical emergencies and cardiac surgery. Part 1 has already dealt with life-threatening drowning, asthma, anaphylaxis and poisoning.
