Patient positioning is important to a successful examination. The patient should lie on his or her left side, which facilitates insertion of the endoscope and may reduce aspiration by allowing gastric contents to pool in the fundus. A small pillow may be used to support the patient's head. One exception to the left lateral position is during placement of a PEG tube where the patient would be placed in the supine position. Vital signs should be obtained prior to initiation of moderate sedation, and nasal oxygen administered. A bite block, either with or without a neck strap, should be placed prior to the administration of moderate sedation. The patient should be instructed not to talk to the physician or staff after administration of sedation to allow the intended effects of sedation to occur and so that appropriate response to sedation can be monitored.
