Introduction: Flexible bronchoscopy is one of the most widely performed procedures for diagnosis of various bronchopulmonary diseases. Most patients tolerate the procedure well although cough is often reported as a distressing symptom.

Objectives: The main objective of the study is to find the comparison of 1% versus 2% lignocaine for airway anaesthesia in flexible bronchoscopy.

Material and methods: This randomized control trial was conducted in pulmonology department of DHQ Hospital Faisalabad and the duration of this study was from July 2018 to December 2018. The data was collected with the permission of ethical committee of hospital. Data was collected with the permission of ethical committee of hospital. The data was collected through random sampling technique. Demographic and baseline values of all the selected patients were collected. Before the start of the bronchoscopy procedure, blood pressure, heart rate, respiratory rate, and pulse oximetric saturation were recorded and monitoring continued during the procedure.

Results: The data was collected from 100 patients with mean age 44.56±2.45 years in group I and 46.78±2.34 years in group II. The demographic and baseline values were similar in both groups. Table 01 explains all the basic parameters of both groups. Fifty subjects each were randomized to 1% and 2% groups, and all randomized subjects completed the study protocol. The cumulative dose of lignocaine administered in 2% lignocaine group was significantly greater than in 1%. The doses of midazolam in 1% and 2% lignocaine groups administered were similar

Practical implications: After this trial we may apply this procedure for airway anaesthesia in flexible bronchoscopy

Conclusion: It is concluded that there was no significant difference in operator-rated overall procedure satisfaction or cough in between the two groups.
