About
It is unclear whether a topical pharyngeal anesthesia adds any benefit to the upper gastrointestinal endoscopy under a propofol sedation. We hypothesize that a topical pharyngeal anesthesia does not ease the upper gastrointestinal endoscopy under propofol sedation. The aim of this study is therefore to quantify the impact of a topical pharyngeal anesthesia to the upper gastrointestinal endoscopy in patients sedated with propofol.
Patients will be randomized to receive a topical pharyngeal spray containing either an anesthetic drug (lidocaine 10%) or a placebo. Thereafter the upper endoscopy will be conducted in its standard manner.
