Subarachnoid spinal analgesia. A comparative survey of current practice in Scotland and Sweden.

A postal inquiry into the current use of subarachnoid spinal analgesia obtained replies from approximately 70% of consultants in both Scotland and Sweden. Although medico-legal anxiety was still an important feature of Scottish practice, the publication of large series with a low incidence of complications had also exerted some influence, and 40% of consultants employed the technique. In contrast, 70% of Swedish replies indicated current use of spinal analgesia and the individual frequency of administration was considerably higher. The present popularity of epidural analgesia has contributed to some decline in the use of subarachnoid spinal analgesia in Sweden, particularly in the case of longer surgical procedures. Anaesthetists in both countries expressed dissatisfaction with the limited choice of available spinal agents and considered their duration of action to be inadequate. In Scotland, conditional indications, such as diabetes mellitus and respiratory disease, were of major importance, whereas Swedish users more often specified surgical procedures for which subarachnoid spinal analgesia was considered to be the anaesthetic of choice. Few anaesthetists had experience of complications and no major neurological sequelae were reported. More than 80% of replies indicated that subarachnoid spinal anaesthesia had a useful place in anaesthetic practice.
