Myocardial ischaemia/reperfusion situations may occur during the perioperative period. The cardioprotective effects of anaesthetics have been known for a long time: volatile anaesthetics reduce the ischaemic cell damage and infarct development. Besides ischaemia, reperfusion itself can also lead to cellular damage, thereby further increasing the ischaemic injury (reperfusion injury). ⋯ The common pathway of the signal transduction cascade of both ischaemic and chemical preconditioning includes the sarcolemnal and/or mitochondrial ATP-sensitive potassium channel. Volatile anaesthetics can imitate the protective effects of a short ischaemia, thereby producing chemical preconditioning. This effect depends, at least in part, on anaesthetic-induced opening of ATP-sensitive potassium channels.

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 A subclavian triple-lumen catheter was retracted until intra-atrial ECG indicated reversal to a normal P-wave.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.

When caring for patients with an incurable progressive disease, the physician experiences a feeling of powerlessness because there is no curative treatment that he can offer. The reaction to this must not be resignation, but active palliative medicine to achieve the best possible quality of life for the remaining time. Palliative medicine is a holistic concept of treatment in an outpatient or inpatient setting, integrating physical, psychological, social and spiritual aspects. ⋯ The decision-makers in our health care system are called upon to support palliative medicine and ensure access to palliative care all over the country. Palliative medicine was started to ease suffering, preserve or restore autonomy and maintain dignity. As an active life aid it is, in our opinion, an alternative to any demand for euthanasia.

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.

[Postoperative epidural analgesia--current status, indications and management].
We are reporting on postoperative pain treatment using epidural analgesia in 1,822 patients, performed between 1995 to 2000, following continuous epidural anaesthesia combined with general anaesthesia for operations in various specialized areas (general or visceral surgery, vascular and thoraxic surgery, gynaecology, urology and orthopaedics). A total of 1,727 of these postoperative epidurals were included in a detailed evaluation. The postoperative epidural analgesia consisted of a continuous application of 0.25% bupivacain or 0.2% ropivacain. ⋯ This reveals the required puncture height. The following side-effects resulting from the epidural analgesia were found: blood pressure loss of more than 20% of the starting value (21%), temporary bladder voiding disorders (8%), temporary sensory disorders of the lower extremities (6.5%), seldom nausea (2.4%) and post-puncture headaches (1.2%). The most important prerequisites for successful postoperative epidural analgesia and thus for increased patient satisfaction are correct selection of the insertion height in relation to the planned operation, constantly available medical pain service, the inclusion of trained care personnel and unequivocal written instructions.
