1% vs. 2 % Lignocaine for Endobronchial Ultrasound Guided Transbronchial Needle Aspiration

August 21, 2017 updated by: Karan Madan, All India Institute of Medical Sciences, New Delhi

Comparison of 1% Versus 2% Lignocaine for Topical Anaesthesia in Endobronchial Ultrasound Guided Transbronchial Needle Aspiration

Endobronchial Ultrasound Guided Transbronchial Needle Aspiration (EBUS -TBNA) is commonly performed for diagnosis of mediastinal pathologies. The procedure can either be performed under general anaesthesia or under moderate sedation with topical anaesthesia. Most patients tolerate the procedure well although cough is often reported as a distressing symptom. Topical lignocaine is administered during bronchoscopy for local anaesthesia. There is no literature on the efficacy of lower concentrations (1%) versus a higher (2%) during EBUS TBNA. This study would help to determine whether 1% lignocaine is as effective as 2% lignocaine for airway anaesthesia during EBUS-TBNA.

Study Overview

Detailed Description

For all patients meeting the inclusion criteria, the demographic profile including age, sex, weight, smoking history shall be recorded. A written informed consent will be obtained from all participants. The patients who undergo EBUS-TBNA under moderate sedation would be randomised in a one is to one ratio either to 1% lignocaine or 2% lignocaine group. Prior to EBUS-TBNA, Blood pressure, pulse rate, respiratory rate and pulse oximetry saturation will be recorded at the baseline Patients in both the groups shall be prepared in a similar fashion except for the concentration of lignocaine used. Two different concentration of lignocaine solution will be labelled as solution 'A' or solution 'B' containing either of 1% or 2% lignocaine solution .Operator will be provided either solution A or B based on the initial randomisation.

During the procedure, 1.5ml aliquots of the provided lignocaine solution will be delivered through the bronchoscope using spray-as-you go technique. The total number of aliquots used during the procedure will be recorded. The patients would be monitored for any adverse effects throughout the procedure. The bronchoscopist doing the procedure will be provided 2 VAS charts to mark the severity of cough and overall procedure satisfaction.

Post procedure, patients will record the pain experienced while undergoing the procedure on the faces pain rating scale.
