The investigators tested whether a new method which additional lidocaine spray on the tip of endoscope can increase the tolerance of examinee during endoscopy than conventional pharyngeal anesthesia alone.
All the patients underwent upper gastrointestinal endoscopy were consecutively enrolled and assigned to case group treated with additional 2 puffs of the 10% lidocaine spray on the tip of endoscope before intubation or control group with conventional pharyngeal anesthesia without further treatment. And the investigators compared their baseline characteristics, past history, sedation or not, and frequency of retching and belching were measured during the endoscopy.
