Ambulatory surgical care is intended to save healthcare expenditure from the economical viewpoint. From the patients point of view significant advantages as well as specific disadvantages of ambulatory surgery are known. ⋯ Reducing the surgical trauma by minimally invasive surgical techniques and very good controllability by modern anesthesia concepts is making the management of the postoperative period crucial for successful ambulatory surgery. Most of the complications and common problems during the postoperative period, such as pain, nausea and vomiting, are not specific for ambulatory surgery, but management places an increasing burden of responsibility not only on general and specialised physicians, but also on other health professionals, patients, and family members.

Case Reports
[Secondary cranial extension after spinal anesthesia with isobaric 0.5% bupivacaine following postural change].
Inadvertent cranial extension of sympathetic and sensory block following posture change during spinal anaesthesia has been reported for isobaric as well as for hyperbaric local anaesthetics. We present the case of a patient who underwent surgical repair of a refracture of the tibia under spinal anaesthesia with 17.5 mg of isobaric 0.5% bupivacaine. The maximum level of sensory block (MLSB) reached T8 after 15 min. ⋯ This case shows that after assumed fixation of the local anaesthetic an inadvertent extension of the MLSB following posture change is possible. Close surveillance is recommended for patients with central neuraxial blocks until the block is in complete remission. The mechanisms for inadvertent high extension of the MLSB following posture change are discussed.

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.

Randomized Controlled Trial Clinical Trial
[Haemodynamic effects following preoperative hypervolemic haemodilution with hypertonic hyperoncotic colloid solutions in coronary artery bypass graft surgery].
Using hyperoncotic colloids as volume replacement to provide haemodynamic stability appears to be a suitable approach to diminish fluid overload and subsequent interstitial edema during cardiac surgery. The aim of the present study was to investigate for the first time the haemodynamic effects following preoperative haemodilution with different hypertonic hyperoncotic colloid solutions in patients undergoing coronary artery bypass grafting. ⋯ Compared to isotonic saline solution, preoperative volume replacement with hyperoncotic colloids improves haemodynamic conditions during the pre-bypass period in patients with normal left ventricular function undergoing coronary artery bypass grafting. Additionally intraoperative crystalloid solution requirements are reduced. The volume saving effects are increased with administration of hyperoncotic colloids in a preparation with hypertonic saline solution, whereas the choice of the colloid, either hydroxyethyl starch or dextran seems to be of minor importance.

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.
