Background: Topical anesthetics commonly used in fiber-optic bronchoscopy (FOB) procedure. This study compare spray and nebulized topical anesthetic in patients undergoing FOB.
Methods: Quasy experimental study was conducted at Adam Malik Hospital Medan with subject whose undergoing FOB. Randomly, each subject sprayed with 10% lidnocaine 5-7 sprayer (N= 32) or nebulized 5 mL of 2% lidocaine (N= 32). In addition, each subject will receive 2% lignocaine through the bronchoscope under direction the operator. All patients had done standard prebronchoscopy preparation and received diazepam 5 mg intramuscularly for premedication 3 hours before procedure and also sulfas atropin 0.25 mg subcutan 30 minute before procedure. Frequency of cough during procedure are recorded and after procedure patients were asked to indicate the degree of discomfort in Visual Analoque Scale.
Results: Mean of lidocaine dose was 204.38 mg on sprayed group vs 170,94 mg of nebulized group. Cough were found in 37.5% in sprayed group vs 25.0% of nebulized group. Mean VAS score was 1.60 cm vs 1.65 between two groups (nonsignificant). Cough and VAS did not significant different between those two groups, with p value 0.410 and 0.378.
Conclusion: The effect of spray and nebulized topical anesthetic are equally to reduce patient discomfort undergoing FOB. (J Respir Indo. 2015; 35: 72-7)
