Radial artery cannulation.
The status of radial artery cannulation is reviewed. The technique of percutaneous puncture, equipment in use, and known complications are discussed. Recommendations are made for precautionary measures to reduce the complication rate. It is concluded that radial artery cannulation is a safe and useful procedure in certain anaesthetic and intensive care situations.

Anaesthesia and clinical pharmacology: related disciplines.
The disciplines of anaesthesia and clinical pharmacology are related in as much as both have a mutual interest in the safe and conservative use of drugs in man. Anaesthetists have effectively been practising rational therapeutics for many years and they have much to offer academic departments of clinical pharmacology in terms of teaching and research programmes. Similarly, the clinical pharmacologist can usefully contribute to anaesthetic training and research programmes in relation to aspects such as education, precise analytical methods, data-handling and clinical trial techniques. The inter-relationship of the two disciplines can be of mutual advantage and has the potential to provide a stronger basis for sound therapeutic practice.

Systemic absorption of epinephrine after endoscopic submucosal injection in patients with bleeding peptic ulcers.
Epinephrine injection is an effective, simple, and economical method of endoscopic hemostasis for bleeding peptic ulcers. We measured catecholamine levels in 18 patients with actively bleeding ulcers (8 gastric ulcers and 10 duodenal ulcers) treated by endoscopic injection. Injection of epinephrine (1:10,000 IU) was given until bleeding from the ulcers stopped. Catecholamine levels were assayed by high-pressure liquid chromatography. Immediately after the injection the plasma level of epinephrine rose by four to five times above the basal level and returned to the baseline in 20 minutes. Norepinephrine levels were not significantly raised in these patients. No cardiovascular complications were seen. Although adverse cardiac events have not been recorded, it seems prudent to monitor these patients closely during and immediately after epinephrine injection.

Defining adult respiratory distress syndrome.
Adult respiratory distress syndrome is a continuum of severe, evolving, diffuse lung injury, often complicated by multiorgan failure. Its pathophysiology is unclear and its treatment is empirical. It is diagnosed clinically using criteria that have no consensus and do not address underlying mechanisms.
