[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.
