Technical

The use of penthrane in anesthesia was first reported by JF Artusio in 1960. He and his colleagues described its administration to 100 patients by closed, semi-closed, and open techniques. It is therefore not surprising that Penthrane was soon used in self-administration systems, and its analgesic properties led to its use to relieve the pain of labour. The development of the Analgizer followed logically from the use of Trilene inhalers, but it was notable as the first disposable analgesic inhaler. The inhaler comprised a plastic cylindrical tube fitted with a mouthpiece and containing a wick; it had no valves, but an orifice allowed the patient to dilute the Penthrane with air. It provided a Penthrane concentration of 0.75 to 0.85%. Its advantages included its small size, its light weight, its use without a face mask, and its disposability. (ref.1)
