Study summary

compare the efficacy and safety of nebulized lidocaine, oropharyngeal lidocaine spray, or their combination for better outcome of topical anesthesia in subjects undergoing diagnostic FB; severity of cough , pain during procedure , cumulative dose of anesthesia needed and its adverse reaction , overall satisfaction .

Read the detailed description

Flexible bronchoscopy (FB) is a commonly performed procedure in the diagnosis and treatment of several respiratory disease. Although FB is generally a short procedure, it is uncomfortable for the patient. At least the use of topical anesthesia during FB is essential, especially when performed without sedation. Effective topical anesthesia blunts airway reflexes such as gag, cough, and laryngospasm.

The reduction in cough not only improves patient comfort but also makes the procedure easier for the operator.

Among agents used for topical anesthesia, lidocaine is the most widely used drug because of its safety and favorable pharmacokinetic profile.

Lidocaine is available in various formulations (gel or solution) and can be delivered to the respiratory passages by using different modes (spray, nebulization, transtracheal injection, bronchoscope instillation, and others).

In this study, will compare the efficacy and safety of nebulized lidocaine, oropharyngeal lidocaine spray, or their combination for topical anesthesia in subjects undergoing diagnostic FB, for better outcome.

Study arms

  • Experimental
    Nebulized lidocaine

    Subjects in group A underwent nebulization with 5 mL of 2% lidocaine for 15 minutes by using a jet nebulizer.

    Procedure: Nebulized lidocaine

  • Experimental
    Lidocaine spray

    In group B will underwent 10% lidocaine spray solution will be sprayed 10 times at the oropharynx at 5 s interval.

    Procedure: Lidocaine spray

  • Experimental
    Combination( Nebulized lidocaine and lidocaine spray)

    Group C: both nebulization and spray will be performed in the same manner except the number of spray will be 2 instead 10.

    Procedure: Combination of nebulized lidocaine and lidocaine spray

What researchers measure

Primary outcomes

  1. The severity of cough using cough severity index

    Assess the severity of cough during and within 4 hours after the procedure as (0 : absent cough is better ) , ( 5 : disturbing cough is the worst )

    Time frame: During and within 3 hours after procedure

  2. pain during the procedure rated by the subjects on the Faces Pain Rating Scale.

    As (0 : no pain , the best) , ( 10 : worst pain )

    Time frame: During and within 3 hours after procedure

  3. time taken to cross the vocal cords.

    the median time in seconds will be calculated during the procedure from the introduction the tip of bronchoscope from the nostril to second at which the tip of bronchoscopy cross the the vocal cords.

    Time frame: at the beginning of the procedure(time zero) till seconds after crossing the vocal cords

  4. changes in heart rate

    changes in the heart rate from the baseline before procedure

    Time frame: During and within 3 hours after procedure

  5. Changes in oxygen saturation

    changes in the oxygen saturation from the baseline before procedure

    Time frame: During and within 3 hours after procedure

Secondary outcomes

  1. cumulative dose of lidocaine administered during the procedure.

    Less cumulative dose of lidocaine needed during the procedure is better

    Time frame: During the procedure

  2. adverse reactions to lidocaine

    assess for any adverse effects related to lidocaine use especially arrhythmia or other adverse effects as convulsions, involuntary movements, bronchospasm, and anaphylaxis.

    Time frame: During and within 3 hours after procedure

  3. overall satisfaction with the procedure using likert scale .

    As (1 : strongly disagree , is the worst) and (5 : strongly agree , is better)

    Time frame: During and within 3 hours after procedure
