Case Reports[Caudal anaesthesia in children and the danger of seizures. A case report (author's transl)].
It is necessary for the modern anaesthetist to be familiar with regional anesthetic techniques for children. When it is not possible to intubate a child, the anaesthetist can use this technique (if the extension of operation allows). ⋯ We are also made aware of the importance of the speed of injection in caudal block. A slow injection prevents development of tachycardia, hypertension, muscle cramps and even unconsciousness.

[Morphological changes after permanent nerve block by freezing and ethanol injection of the sciatic nerve of the rabbit (author's transl)].
Permanent nerve blocks by intraneurally injected alcohol are often complicated by alcohol-neuritis. Encouraging clinical experiences with permanent blocks by freezing raises the question whether morphological differences between the nerve lesions could explain the difference in their side effects. On 30 rabbits both sciatic nerves were blocked after surgical preparation. ⋯ The nerve lesions of both types of blockade were complete. That produced by the cryoprobe was limited to the small area of local freezing, whereas the alcohol-block produced the same type of nerve degeneration but with a wide-spread extension reaching the sacral plexus. We discuss whether this slight morphological difference might be sufficient to explain the higher complication rate of alcohol blocks.

[Sex difference related complication rates after spinal anaesthesia (author's transl)].
A retrospective study by questionnaire was carried out on 3056 patients (1457 female and 1599 male patients) to ascertain morbidity after spinal anaesthesia with 0,5% isobaric bupivacaine, with special regard taken to the incidence of post spinal headache. It was found that in female patients below the age of 50 the incidence of complaints was higher than in male patients, especially in the 30-50 year range. In male patients the incidence was higher in the 40-60 year group, with the highest incidence in the 50-60 year olds. ⋯ In patients over 60, the incidence dropped and there was no sex difference. There was a higher incidence of headache with larger needles used for spinal anaesthesia. 84% the headaches cleared up within 2 weeks. Only in 9% did the headache persist longer than 4 weeks.
