Brief summary

Topical Pharyngeal anesthesia (TPA) is widely used during upper endoscopy. Articaine is local anaesthetic that have not been previously evaluated in pharyngeal anesthesia for upper endoscopy. The aim of this study was to compare pharyngeal anesthesia with 4% articaine to placebo (Na0,9%) during gastroscopy in terms of benefit on patients' and endoscopists' satisfaction.

Detailed description

Topical Pharyngeal anesthesia (TPA) is widely used as an adjunct to sedation during upper endoscopy. TPA improves patient tolerance and the ease of endoscopy.1 Methemoglobinemia and anaphylactic reactions are serious complications of such topical anaesthetic agents, as lidocaine, tetracaine, and benzocaine. Articaine is as a unique amide local anaesthetic that possesses both an amide and an ester linkage and this is of clinical significance in minimizing the risk of overdose (toxic reaction). In routine dental procedures, articaine is a superior anaesthetic to lidocaine. Also, in comparison to lidocaine articaine acts faster and its duration of action is shorter what may be an advantage in such relatively fast procedures as gastroscopy. Articaine have not been previously evaluated in pharyngeal anesthesia for upper endoscopy. The aim of this randomised double-blind placebo controlled study was to compare pharyngeal anesthesia with 4% articaine to placebo (Na0,9%) during gastroscopy in terms of benefit on patients' and endoscopists'satisfaction.

Interventions

Articaine is intermediate-acting local anesthetic (amide type). Like other local anesthetic drugs, articaine causes a transient and completely reversible state of anesthesia (loss of sensation) during (dental) procedures. In dentistry, articaine is used both for infiltration and block injections.

OTHER9% Sodium Chloride solution for injection

9% Sodium Chloride Injection, USP is a sterile, nonpyrogenic, isotonic solution of sodium chloride and water for injection. Each mL contains sodium chloride 9 mg. It contains no bacteriostat, antimicrobial agent or added buffer.

MeasureTime frameDescription
satisfaction with gastroscopyone dayVolunteers were asked to evaluate unpleasantness of gastroscopy (0- most unpleasant, 10-most pleasant), overall satisfaction with gastroscopy (0-extremely dissatisfied 7-extremely satisfied)

Secondary

MeasureTime frameDescription
vital signsone dayVital signs (heart rate, electrocardiogram, non-invasive blood pressure, peripheral oxygen saturation, end-expiratory carbon dioxide) will be monitored during the gastroscopy and until the discharge.
easiness of gastroscopy performanceone dayThe easiness of gastroscopy performance will be evaluated by endoscopists' with structured questionnaire.
