[New viewpoints on the mode of action of intravenous regional anesthesia].
The site of action of intravenous regional analgesia is controversial. We developed a new method to investigate if the local anaesthetic primarily blocks the peripheral nerve endings or the main nerve trunks. Intravenous regional analgesia was carried out in six volunteers who received 4 mg/kg prilocaine 1.5%. ⋯ This observation proves that the principal site of action of intravenous regional analgesia is at the peripheral nerve endings. Two further studies, with contrast media and radio isotopes, were carried out to investigate the spread of the injected volume. Both investigations show that the injected volume spreads distally into the fingers.

Case Reports[Horner's syndrome in obstetrics. A rare complication of peridural regional anesthetic procedures].
A case of Horner's syndrome (HS) following lumbar epidural block during labor is described. 10 min after injection of the local anaesthetic the symptoms and signs of HS were recognized. They spontaneously disappeared 60 min later. It is concluded, that HS seems to be a benign complication of epidural anaesthesia which may, however, present the first sign or symptom of an extensive block of serious consequence. Pregnant women in labor receiving epidural block, seem to be predisposed to HS.

Case Reports[Pneumocephalus permangnus. An unusual complication following lumbar anesthesia].
A case is presented of a 53 year old patient who developed pneumocephalus three days after lumbar anaesthesia. Symptoms and neurosurgical treatment are described. Liquor leakage and lowered intracranial pressure as are discussed as possible mechanisms.

Comparative Study[Thoracic peridural anesthesia for intra- and postoperative analgesia in lung resections. A comparison of stress reactions and postoperative lung function].
47 patients who were scheduled for lung resection were assigned to two groups. 23 patients had a neurolept analgesia and postoperatively parenteral analgetics. 24 patients received a combination of thoracic peridural anaesthesia and nitrous oxide-oxygen anaesthesia for surgery. The peridural analgesia was continued for 2-3 days for postoperative pain control. Heart rate and mean arterial pressure were recorded. ⋯ No obstruction was observed. PaO2 and paCO2 showed no clinically relevant differences. During surgery the combination of general and regional anaesthesia results in a lower stress response of the heart and postoperatively it improves lung function which is an important advantage in comparison with systemic analgetics.
