Input (English): Question: Does topical pharyngeal anesthesia improve upper gastrointestinal endoscopy in conscious sedated patients?
Answer: In patients undergoing diagnostic upper endoscopy using intravenous midazolam and meperidine, the use of topical pharyngeal anesthesia does not improve patient tolerance or procedure performance. Elimination of this agent in the performance of diagnostic upper endoscopy will save time and money without adversely affecting patient care or outcomes.
