Anaesthesia for stent graft repair of thoracic aneurysm and coarctation of the aorta.

We present the anaesthetic management of a patient for stenting of a thoracic aortic aneurysm at the site of an aortic coarctation. The specific challenges to the anaesthetist for this case are outlined. These include the specific problems of placing the graft, the obvious risk of aortic rupture and the unfamiliar environment of the separate radiological theatre. The advantages and disadvantages to the anaesthetist of the treatment of thoracic aortic aneurysms with stents are briefly discussed.

Phaeochromocytoma diagnosed during labour.

The diagnosis of phaeochromocytoma during pregnancy is rare. We present the management of vaginal delivery in a woman diagnosed with the condition during labour. A Medline search and follow-up of references failed to find any similar report in the last 30 years.

Randomized placebo-controlled trial to assess the effect of remifentanil and propofol on bispectral index and sedation.

The effect of the combination of opiates and hypnotics on bispectral index (BIS) is unclear. This double-blind placebo-controlled trial investigated the effect on BIS and sedation of different infusion doses of remifentanil combined with a steady infusion of propofol. Forty patients initially received a target-controlled infusion of propofol 2 micrograms ml-1 for 15 min. They were then randomized to receive either placebo, 0.01, 0.05 or 0.1 microgram kg-1 min-1 remifentanil for a further 15 min. We found a significant correlation between the dose of remifentanil and the change of BIS after 15 min of infusion. The correlation between all the sedation scores and their corresponding BIS was also significant. We concluded that remifentanil, in combination with propofol, reduces BIS when used for sedation.

Ether in an isoflurane vaporizer and the use of vapour analysers in safe anaesthesia.

A Penlon Sigma isoflurane vaporizer was found to contain some diethyl ether. This had escaped from a ruptured temperature compensation device within the vaporizer. The Datex AS/3 vapour analyser detected the foreign agent and displayed a warning. Different types of vaporizer compensation devices are highlighted and the use of vapour analysers is discussed. We conclude that these analysers are invaluable for indicating that the patient is receiving the correct concentration of an inhalation agent but are of little use in the detection of all but a few possible contaminants.
