We have studied the effects of enflurane on intracranial pressure (ICP) in 9 neurosurgical patients, whose ICP was continuously monitored for therapeutic or diagnostic purposes. The control ICP was under 15 Torr in 5 cases, under 20 Torr in 3 cases and of 25 Torr in one case. In order to achieve stable ventilatory conditions, the patients were kept under controlled ventilation, breathing a mixture of 60 to 70% nitrous oxide and oxygen. ⋯ The overall changes, however, are not significant. There is a small significant decrease of MAP and CPP under 2% enflurane when compared to control, of probably no clinical importance (under 10% change). Our results do not show that enflurane is entirely without effect on ICP, but we think that 1 to 2% enflurane may be used in neuroanesthesia with a reasonable margin of safety, in association with slight hyperventilation and other means or reducing ICP, in accordance to clinical requirements.

An anterior approach to the block of the sciatic nerve is described. The procedure has been applied in over 780 patients. It is quick, simple, safe and free from any serious complications.

The use of analgesic drugs is only one part of a multidisciplinary approach which offers also other possible palliative procedures for pain therapy. Pain complaints are placed against the background of terminal illness. ⋯ The way of adminstration may have some impact on the efficacy of the analgesic regimen. Side effects and concomitant medication are reviewed.

Controlled administration of oxygen with self inflating resuscitation bags.
Resuscitation bags were originally developed to ventilate patients under emergency conditions. Under circumstances where oxygen is available one should make full use of it. The problem of exact air enrichment for these bags has not been satisfactory solved until now. ⋯ This is obtained via a venturi device connected to the air inlet of the manual resuscitation bag. The FIO2 delivered to the patients from a self inflating bag was tested for values of 24, 30, 40 and 50% oxygen. The new system proved to be capable to delivery exact FIO2 in contrast with previously applied methods of oxygen delivery where this could never be achieved.
