AbstractEndoscopic submucosal dissection is associated with a longer treatment time and a higher risk of patient discomfort than conventional procedures. Adequate, safe sedation is therefore essential. Sedation can cause adverse effects such as hypoxemia and hypotension, requiring continuous intraoperative and postoperative monitoring of blood pressure, use of the electrocardiogram, and arterial blood oxygen saturation by pulse oximetry. A physician and a nurse solely responsible for sedating and monitoring the patient should be present during treatment.A combination of benzodiazepines and analgesics are generally used for sedation, but new sedatives such as propofol and dexmedetomidine hydrochloride are expected to be useful agents. Endoscopists should become more familiar with sedatives, analgesics, and emergency procedures in the future.© 2013 The Authors.
