Brief Summary:
At recent, the number of patients who underwent sedated esophagogastroduodenoscopy has been on the increase. For such patients, whether topical pharyngeal anesthesia is needed remains to be controversial. European Society of Gastrointestinal Endoscopy, European Society of Gastroenterology and Endoscopy Nurses and Associates, and the European Society of Anaesthesiology Guideline for non-anesthesiologist administration of propofol for GI endoscopy have not made any recommendation, because the role of pharyngeal anesthesia during propofol sedation for upper digestive endoscopy has not been assessed. Our study aimed at investigating whether topical lidocaine pharyngeal anesthesia could benefit patients who underwent esophagogastroduodenoscopy under propofol sedation.

Condition or disease Intervention/treatment Phase
Esophagogastroduodenoscopy Procedure: Topical lidocaine pharyngeal anesthesia Not Applicable

Detailed Description:
Propofol sedation has been widely applied in endoscopic examinations. For such patients, whether lidocaine topical pharyngeal anesthesia should be administrated is still in doubt. Considering the fact that lidocaine anesthesia may cause airway narrowing and anaphylaxis, it is important to clarify the role of lidocaine topical pharyngeal anesthesia in esophagogastroduodenoscopy under propofol sedation. Our study could test whether lidocaine topical pharyngeal anesthesia should be performed in sedated esophagogastroduodenoscopy in a randomized controlled trial.

Arm Intervention/treatment
Experimental: Experimental group
Topical lidocaine pharyngeal anesthesia was performed.
Procedure: Topical lidocaine pharyngeal anesthesia
Topical pharyngeal anesthesia by lidocaine was administrated 4-5 min before propofol sedation in patients who underwent esophagogastroduodenoscopy.

No Intervention: Control group
No topical lidocaine pharyngeal anesthesia was performed.

Primary Outcome Measures :
  1. Immediate throat pain score [ Time Frame: 1 day ]
    Immediate throat discomfort will be recorded, and pain score (0 no pain - 10 most painful) will be given by the patients.

Secondary Outcome Measures :
  1. Throat discomfort 1 day after the procedure [ Time Frame: 1 day ]
    All the patients will be followed up by telephone 1 day after the endoscopic examination. Throat Discomfort will be recorded.

  2. Adverse events [ Time Frame: 1 day ]
    All the adverse events during the sedated endoscopic examination will be recorded.

  3. Satisfaction score [ Time Frame: 1 day ]
    Patients will give a satisfaction score of 0 (unsatisfied) -10 (very satisfied) based on their own experience.
