A case of blunt trauma to the neck is presented. While driving an all terrain vehicle (ATV), a 20-yr-old male was struck across the anterior neck by a cord suspended between two poles. ⋯ Intractable cerebral oedema developed, and the patient died five days after the initial insult. Such injuries should alert the clinician to the possibility of major vascular injury, and if suspected, angiography is warranted.

A prospective study was undertaken to determine the cardiovascular response of a continuous alfentanil infusion during abdominal aortic surgery (AAS). Each subject (n = 20) received a beta-blocking drug preoperatively, and was premedicated with oral lorazepam. Anaesthesia was induced with alfentanil 50 micrograms.kg-1 and thiopentone 3 mg.kg-1, and was maintained with a variable rate infusion of alfentanil and 66 per cent nitrous oxide in oxygen. ⋯ However, there was a 33 per cent incidence of myocardial ischaemia on the first postoperative day. There were no myocardial infarcts and no deaths. We conclude that in beta-blocked patients undergoing aortic reconstructive surgery, a variable rate alfentanil infusion administered with 66 per cent nitrous oxide provides anaesthesia characterized by good haemodynamic control without the need for supplemental agents or vasoactive drugs.
