The operating unit is one of the cost-intensive facilities in a surgical clinic with a pacemaking function for most of the internal procedures. The power of performance of the operating unit is based on the cooperation of all disciplines and professions involved. The key to management of the operating unit is not only to coordinate the daily procedures, but also to interact with support personnel. ⋯ Better transparency of operations in the OR contributes to increased efficiency. Implementation of quality management is the foundation for a successfully operating surgical hospital. Not only the productivity of individual members of the staff, but also the precise documentation of the quality of results will become important parameters in a successful surgical hospital, whose nucleus is the OR.

What is the effect of preoperative acute normovolemic hemodilution (ANH) with 6% hydroxyethyl starch (HES) 130/0.4 (Voluven) on blood volume? ⋯ Double label measurements of blood volume demonstrated that the volume effect of 6% HES 130/0.4 (Voluven) is about 100% in the course of ANH. The reason for the disproportionally large decrease in hematocrits could be the mobilization of a fraction of the plasma volume which was retained within the endothelial glycocalyx.

Case Reports
[Chylothorax after central venous catheterization. Considerations to anatomy, differential diagnosis and therapy].
The authors report on a chylothorax, a rare, although classical complication of left internal jugular vein cannulation. The anatomy of major lymphatic vessels including variations is illustrated. The mechanisms of central venous catheter associated chylothorax are discussed. Likewise described are pathophysiology, signs, clinical features, and differential diagnosis with special consideration of the triglyceride content as well as treatment options.

Comparative Study
[Anesthesia for cesarean section of obese women. Results of a four-year observation].
Regional anaesthesia is recommended for caesarean section in obese women. With regard to this aspect anaesthesia practice in the obstetrics department of the University Hospital Kiel was evaluated retrospectively. ⋯ Obesity is a common risk factor in caesarean section anaesthesia. Spinal anaesthesia can be recommended even for obese parturients.

Modern anesthesiology employs the combined administration of several drugs belonging to different pharmacological classes. Additionally, anesthesiologists are facing the challenge of polypharmacy regimens utilized by patients considered for surgical treatment When drugs are combined, the pharmacological effect may considerably differ from the individually expected properties. This may be beneficial or potentially lead to adverse drug reactions harming the patient. ⋯ Depending on the mechanism involved, drug interactions can be classified as pharmaceutical, pharmacodynamic, or pharmacokinetic. Although there are enormous possibilities for adverse drug reactions nd the complexity is hard to identify, prediction of drug interaction is possible. Besides recognizing the general risk factors, fundamental knowledge of basic and clinical pharmacology is important to prevent serious or fatal drug interactions before they occur.
