monomyth

About 20 years ago, an American research team began experimenting with a Canadian invention, a bedside self-medication machine programmed to deliver about 1 mg of morphine intravenously to patients who pressed a hand button. The machine limited infusions to one every six minutes. In one early study, fifty patients were kept on the regimen between one and six days. The self-administered doses were considerably less than the maximum the machine would allow. Rather than increasing as patients continued the regimen, the doses progressively declined (Bennett, et al., 1982).
