Case Reports[Accidental hypothermia--a challenge for rescue service and intensive care].
Accidental hypothermia is a rare clinical picture with different causes. Specific features are shown by patients who have accidents in water, due to rapid cooling. The SARRRAH project (Search and Rescue, Resuscitation and Rewarming in Accidental Hypothermia) was launched to secure fast and professional medical care right up to rewarming by extracorporal circulation. ⋯ Five of the non-survivors belonged to the group of eight patients who were rewarmed by extracorporal circulation. With one exception, they also had the lowest core temperatures. Only a homogeneous and up-to-date documentation will allow further conclusions to be made for improving the concept of therapy.

Case Reports[Do position control methods for central venous catheters prevent complications? Hydromediastinum caused by an initially correctly placed tri-lumen subclavian catheter by using intra-atrial ECG recording--a case report].
Central venous catheters (CVCs) can be associated with various complications which arise during insertion, with the catheter in situ or upon its removal. Here we report a case of secondary CVC malposition that occurred despite checks of CVC position by different methods. A subclavian triple-lumen catheter was retracted until intra-atrial ECG indicated reversal to a normal P-wave. ⋯ Moreover, repeated chest radiographs are useful in verifying a correct CVC position and detecting late complications. In summary, CVC complications can occur with delay, are potentially life-threatening and may necessitate repeated checks of catheter position. This case report discusses different approaches to detecting malposition and reviews rare CVC complications.

Case Reports[Critical infusion incident caused by incorrect use of a patient-controlled analgesia pump].
We report on the case of a 17-year-old male patient who received a PCA pump after nephrectomy for postoperative analgesia. The syringe of the PCA pump was filled with 50 mg morphine and positioned about 25 cm above the heart. Since the piston of the syringe was not bolted while the pump was switched off, an unnoticed accidental evacuation of the whole content of the syringe into the intravenous line of the patient occurred because of gravity. ⋯ This critical incident was caused by various factors: incorrect application in combination with insufficient experience or training, stress, inadequate handing-over of the patient and a lack of arrangements and instructions for procedures in routine situations. Suggestions for preventing such dangerous critical incidents are made and discussed. In particular, an algorithm for the correct procedure when inserting or changing the syringe of a syringe pump is presented.

Randomized Controlled Trial Comparative Study Clinical Trial[Comparative studies of patient positioning for lumbar intervertebral disk operation].
For surgery on lumbar disks by the posterior route, patients are placed either on a Wilson frame or in genupectoral position. The aim of the prospective study was to record and describe the haemodynamic changes resulting from the patients' position. After written informed consent had been received, 80 neurosurgical patients undergoing lumbar disk surgery were randomly divided into two groups; group I--Wilson frame, group II--genupectoral position. ⋯ We recommend the Wilson frame for neurosurgical lumbar disk surgery in cases of cardiovascular or cerebrovascular disorders. The adaptive capacities in the genupectoral position as a result of the modifying distribution of blood volume are limited in these patients. Furthermore, the dose-dependent effects of different anaesthetics on haemodynamic parameters in these prone positions should be explored.

Randomized Controlled Trial Comparative Study Clinical Trial[Cis-atracurium--an equivalent substitution for atracurium in pediatric anesthesia?].
Cis-atracurium is a stereoisomer of atracurium, about five times more potent than the racemate. Whereas cis-atracurium is routinely used in adults, its effects on children are still poorly defined. We compared equipotent doses of atracurium and cis-atracurium in children aged between 2 and 12 years regarding the quality of neuromuscular blockade, the intubation conditions and the occurrence of side-effects. ⋯ Flush and tachycardia occurred much less frequently and there were no significant differences in the two groups: two patients in group A and only one in group C. The authors conclude that atracurium and cis-atracurium lead to comparable neuromuscular effects in children aged between 2 and 12 years. Only the intubation conditions were better after atracurium, but atracurium was followed by urticaria more often than cis-atracurium.
