Summary

This study designed for compare efficacy of following two anesthetic method for transnasal endoscopy * "Catheter-free method" * "Catheter-insertion method"

Detailed description

1. Check of the medical history (both method) 1. underlying systemic disease 2. drug allergy 3. anticoagulant or antiplatelet use 2. Premedication (both method) 1. taking premedication contain dimethylpolysiloxane, pronase, sodium bicarbonate for improved endoscopic visualization 2. spraying naphazolin acetate into nasal cavity for decrease secretion 3. Different anesthetic method for transnasal endoscopy 1. "Catheter-free method" : spraying epinephrine into nasal cavity 2. "Catheter-insertion method" : spraying both epinephrine and lidocaine into nasal cavity

Conditions

• Pretreatment Method of Transnasal Endoscopy

Interventions

Type	Name	Description
PROCEDURE	pretreatment method for transnasal endoscopy	Catheter-free method : The patient then takes simethicone (10cc). After that, the nasal cavity is sprayed with epinephrine (1cc) and lidocaine HCL (4%, 4cc). Catheter inesertion method: After preparation steps the same as in the 'catheter-free' method, a 14 Fr. flexible catheter is coated with 2% lidocaine HCL gel and 8% lidocaine HCL spray. After that, the catheter is inserted into the patient's nasal cavity, and maintained about 1 minute for anesthesia. A 16 Fr. catheter is prepared by the same method with as the 14Fr. catheter. After the 14 Fr. cathter has been removed from the patient's nasal cavity, the 16 Fr. catheter is inserted into the patient's nasal cavity.
