Filter by:OBJECTIVE: To study the safety, efficacy and clinical significance of remimazolam in the diagnosis and treatment of elderly obese patients with daytime gastrointestinal endoscopy, calculate the optimal dose, and conduct relevant verification. Provide a safer and more effective anesthesia solution for the growing special population. METHODS：Around 160 patients were selected to receive painless gastroenteroscopy.，they were divided into four groups of D1, D2, R and C. Group D1 and D2(including 60 patients) were used to calculate the ED50 and ED95 of the drug. According to up-and-down method, they were slowly injected 0.3μg/kg of remifentanil in advance, then 0.20mg/kg of remimazolam, and gastroscopy was performed after MOAA/S score ≤３. The next patient would be increased 0.05mg/kg of remimazolam if there is a positive standrd, otherwise it would be decreased 0.05mg/kg. And the study was terminated when seven crossing points occurred. One hundred patients were randomly divided into two groups of R and C.Before administration of remimazolam, remifentanil injection 0.3 μg/kg were given intravenously in two groups, respectively (injection rate was 30 s).Then group R was given the calculated dose of remimazolam, and group C was given propofol 1.5-2mg/kg.The success rate of sedation, changes in vital signs, adverse reactions, and postoperative recovery were recorded in the two groups.
This study aims to test the effectiveness of virtual reality (VR) as a non-pharmaceutical intervention to reduce pain and anxiety in children undergoing painful procedures in Phlebotomy, Radiology, Infusion, Orthopedics, Gastroenterology, and Immunology, amongst others, at CHLA, as measured by self- and proxy-report. Examples of the painful procedures include IV sticks, cast removals, allergy testing, and anorectal manometries.
With this study, we plan to review the performance of colonoscopy in colon cancer screening and surveillance, especially with the recent improvements in endoscopic technology (high definition endoscopes), use of split dose preparation which provides excellent colon preparation for detection of lesions and increasing awareness and detection of flat lesions of the colon. The findings will help us define the role of colonoscopy screening of colon polyps and flat lesions and identity areas for improvement. The data will be used for continuing quality improvement and presenting our outcomes at academic meetings and publishing our results in peer reviewed journals.
