Although pediatric radiologists do practice age-adjusted helical CT, variable scanning techniques are used, potentially delivering high doses of radiation. Information on current practices in helical CT of the body in children can serve as a foundation for future recommendations and investigations into helical CT in pediatric patients.
Physicians often have limited experience of carbon mon oxide poisoning, and regional and national poison units are regularly contacted for advice. To improve the situa tion a 24-hour/365 days a year advice line was created to advise both hospital accident and emergency depart ments and poison units. This service started in January 1996. All calls to the service are initially dealt with by a first responder whose aim is to identify 'critical answers' and act accordingly. If the patient's poisoning is suffi ciently severe, then onward referral to a hyperbaric unit may be appropriate. In addition to patient care, the CO advisory service provides training and lectures for all hospitals that request this support. To date the total referrals can be broken down as accidental poisoning (51%), smoke inhalation (27%), non-accidental poison ing (21 %) and cause unknown (1 %). This is in contrast to the general perception that non-accidental poisonings make up the vast majority of cases. The service under takes to follow the progress of the patient until all issues are resolved and to remain available to provide advice and support until it is no longer required. In the future the service hopes to provide data for research and eventual ly to provide leadership in organising and running treat ment trials including the efficacy and value of hyperbaric oxygen therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
