Подробное описание

This study aims to compare the effects of conscious sedation and intravenous general anesthesia on cardiovascular events in frail patients undergoing digestive endoscopy diagnosis and treatment.

Both sets of anesthesia plans completed preoperative evaluations, including blood count, coagulation function, liver and kidney function, and cardiopulmonary function. Routine monitoring of electrocardiograms (ECG), non-invasive blood pressure (NIBP), pulse oximetry (SpO2), open veins, and administration of a balance solution of 3-5ml/kg. h. The conscious sedation group (Group A) received sufentanil 0.05-0.1 5 minutes before examination μ G/kg, administration time 30 seconds, 1-2 mg of midazolam administered 2 minutes before examination; Evaluate the patient's MOAA/S score, insert a digestive endoscope at 2-3 minutes, and add 1-2mg of midazolam if the patient is unable to tolerate coughing or movement during the examination. Reevaluate the MOAA/S score, and continue the operation after 2-3 minutes; Intravenous general anesthesia group (Group B): sufentanil 0.05-0.1 μ G/kg, administration time 30 seconds, 1mg/kg of propofol administered 2 minutes before examination. Depending on the patient's sleep status, 10mg of propofol can be administered every 30 seconds; Evaluate the patient's MOAA/S score. At 0-1 points, a digestive endoscope is inserted. If there is coughing or physical activity during the examination that the patient cannot tolerate, propofol 10-20mg can be administered multiple times. Evaluate the MOAA/S score again, and continue the operation after 0-1 points. All anesthetics should be discontinued before the end of the surgery. Since the examination, blood pressure should be measured every 2 minutes, while HR, SpO2, and RR should be recorded to observe if there are any abnormalities in the electrocardiogram. If there are any abnormalities, please explain until the endoscope is removed from the dental pad. Record the satisfaction of gastroenterologists, anesthesiologists, and patients after surgery. Follow up patients by phone within three days after surgery to determine the incidence of adverse events (dizziness, headache, palpitations, wheezing, mobility, nausea and vomiting).
