BACKGROUND: Clinical trials have shown rofecoxib, a selective inhibitor of cyclo-oxygenase-2, to be associated with fewer gastrointestinal complications than non-selective nonsteroidal anti-inflammatory drugs (NSAIDs).OBJECTIVE: To evaluate the potential clinical and economic consequences of rofecoxib prescription in Ontario, Canada, for patients with osteoarthritis (OA) aged >65 years who did not respond to paracetamol (acetaminophen) therapy.DESIGN: Decision analytic modelling study.METHODS: A model was constructed to compare rofecoxib and nonselective NSAIDs with respect to their gastrointestinal complications in patients air jordan uk with OA. The model had a 1-year horizon and considered direct medical costs from the perspective of the Ontario Ministry of Health. Event rates were estimated from a pooled analysis of 8 phase IIb/Ill clinical trials. All subjects went to a hot bathroom with a high concentration of radon, and nasal inhalation of vapor from a hot spring was performed for 40 min once a day under conditions of high humidity. The room temperature was 48 degrees C; the room radon concentration was 2,080 Bq/m3. Blood samples were collected at 2 h, 14, and 28 days after the first therapy. PURPOSE: To review established techniques and to provide an update on new methods for clinical monitoring of neuromuscular function relevant to anesthesia.SOURCE: A PubMed search of relevant article for the period 1985-2005 was undertaken, and bibliographies were scanned for additional sources.PRINCIPAL FINDINGS: There is no substitute for objective neuromuscular monitoring; for research purposes, mechanomyography (MMG) is the gold standard; however, the most versatile method in the clinical setting is acceleromyography since it can be applied at jordan shoes uk various muscles and has a long track record of clinical utility. Kinemyography is valid to monitor recovery of neuromuscular transmission at the adductor pollicis muscle (AP), whereas phonomyography is easy to apply to various muscles and shows promising agreement with MMG. Monitoring of the corrugator supercilii muscle (CS) may be used to determine the earliest time for tracheal intubation as it reflects laryngeal relaxation better than monitoring at the AP.
