Silmitasertib research buy There is increasing evidence that this procedures can be safely and appropriately performed under general anesthesia with IV propofol where appropriate medical staffs are available and without anesthesia specialists in most circumstances. The use of propofol in endoscopy is now widely performed in most of the western countries. However, the data is lacking in the underdeveloped country. For the first time in Nepal, IV propofol is used at Dhulikhel hospital undergoing gastrointestinal procedure for more than a couple of CHIR-99021 years. Methods: Design: Prospective study of 500 consecutive patients who wished to undergo sedation with IV propofol

were studied during gastroscopy Methodology: All patients undergoing gastroscopy from January 2012 to January 2013 at Dhulikhel Hospital (Tertiary Hospital) in Nepal. Sedation with IV propofol was mostly provided by endoscopists and or trained nurses and in few cases by anaesthesia specialists. During the study the patients were observed for incidence of dose requirement, onset of sedation, loading dose requirement, hypotension, hypertension, bradycardia/tachycardia, arrhythmia, hypoxia, apnea, dyspnea, dizziness, headache, injection site pain, allergy, supplemental

oxygen administration, bag mask ventilation, intubation, recovery from sedation, patient satisfaction, hospital 上海皓元 admission after sedation, death were studied for during and after the procedure. Results: 500 procedures were performed during the period of 1 year. Onset of sedation was observed in 40 seconds to 2 minutes, total dose required was 90 mg to 220 mg, and time to full recovery was 12 to 20 minutes. Minor sedation-related adverse events occurred in most cases including 112 (22.4%) for dizziness, 25 (5%) for headache, 150 (30%) for injection site pain. Other major events occurred were 10 (2%) for hypotension, 50 (10%) for bradycardia, 29 (5.8%) for tachycardia, and 10 (2%) for arrhythmia. Respiratory-related adverse events including hypoxia occurred in 90 (18%) patients requiring oxygen supplementation and 3 (0.6%) required bag mask ventilation however no patients required intubation and hospital admission or death. Anesthesisia specialist was consulted in 15 (3%) cases requiring sedation for prolonged duration especially for intervention endoscopy and in patients with multiple co-morbid conditions in anticipation of major adverse events and its effective management. Conclusion: Propofol can be safely and effectively administered by trained endoscopists and nurses.
