Clinical Trial Controlled Clinical TrialThe efficacy of hyoscine hydrobromide in reducing side-effects induced during immersion in virtual reality.
Regan and Price (1994) investigated the frequency of occurrence and severity of side-effects of using an immersion virtual reality system in 150 subjects: 61% of the subjects reported symptoms of malaise at some point during a 20-min immersion and 10-min post-immersion period. This paper describes a double-blind placebo-controlled study that investigated whether 300 microgram of hyoscine/scopolamine hydrobromide administered to subjects prior to immersion in virtual reality was effective in reducing side-effects experienced during immersion. ⋯ The results of the study showed that the hyoscine was effective in reducing symptoms that are commonly observed during immersion in virtual reality.

Case ReportsSevere carbon monoxide poisoning in the pediatric patient: a case report.
A 10-yr-old female presented at Deaconess Medical Center, Spokane WA, comatose after being rescued from a house fire. Her carboxyhemoglobin was 48%. An 11-yr-old playmate presented with a carboxyhemoglobin level of 51% and later expired. ⋯ Carbon monoxide also exerts a negative influence on the electron transport chain, may lead to delayed neurologic sequelae because of free radical formation, and produces profound changes in the myocardium. Once seen as a capricious treatment for many symptoms, hyperbaric oxygen therapy is now an accepted treatment for carbon monoxide poisoning. The outcome suggests that in a patient whose prognosis is grave, a good outcome may be achieved with aggressive HBO therapy.
