AIM The administration of trans esophageal echocardiography (TEE) may cause nausea, shortness of breath, agitation, emotional distress and pain in patients due to pharyngo-esophageal intubation, which may be partially relieved by sedoanalgesia. The aim of this study was to compare clinical effects of midazolam, midazolam-alfentanil combination and propofol sedation given for sedation and sedoan...

We report the development and use of a synthetic, discrete event, discrete space model that functions as an epithelio-mimetic device (EMD). It is intended to facilitate the study of intestinal transport of drug-like compounds. We represent passive paracellular and transcellular transport, carrier-mediated transport and active efflux using stand-alone components. Systematic verification of the E...

BACKGROUND Estimation of analgesia in anaesthetized children is often imprecise, and consequently, anaesthesiologists commonly evaluate children's response to surgical stimulation by movement or haemodynamic changes. In adults reflex pupillary dilatation has been demonstrated to be a very sensitive measure of noxious stimulation, correlated with opioid concentrations. The autonomic nervous cont...

BACKGROUND AND OBJECTIVES The use of topical anesthesia in cataract surgeries has been increasing, especially after the development of phacoemulsification. The objective of this study was to evaluate the efficacy of topical anesthesia associated with sedation for cataract extraction by phacoemulsification. METHODS A prospective study was conducted with 312 patients, ASA I and II, ages 41 to 8...

Classical midazolam-opioid combination for gastrointestinal endoscopy sedation has been adopted for decades. Dosing regimens have been studied but most require fixed dosing intervals. We intend to use a sophisticated pharmacodynamic tool, response surface model (RSM), to simulate sedation using different regimens. RSM can predict patient's response during different phases of the examination and...

The interactive electronic information storage and transmission system PRESTEL was assessed as a method of recording and collecting patient record forms from a multicentre trial in anaesthesia. PRESTEL terminals were provided in anaesthetic centres around Britain and all data handled by this public viewdata service, which connects users by telephone to a central computer. The trial was of a new...
