COMPARISON OF AIRWAY NERVE BLOCK VERSUS NEBULIZED LIDOCAINE ON HEMODYNAMIC RESPONSES DURING AWAKE FIBEROPTIC INTUBATION

30. mai 2026 oppdatert av: Aniqa Intizar, Mayo Hospital Lahore

COMPARISON OF AIRWAY NERVE BLOCK VERSUS NEBULIZED LIDOCAINE ON HEMODYNAMIC RESPONSES DURING AWAKE FIBEROPTIC INTUBATION, A RANDOMIZED CONTROLLED TRIAL

This prospective randomized controlled trial aims to compare the effectiveness of airway nerve blocks versus nebulized lidocaine in attenuating hemodynamic responses during awake fiberoptic intubation in adult patients with anticipated difficult airways. Eighty patients undergoing elective surgery requiring awake fiberoptic intubation will be randomly assigned to receive either airway nerve blocks (glossopharyngeal and transtracheal blocks with lidocaine) or nebulized lidocaine. The primary outcome will be changes in heart rate and mean arterial pressure during and after intubation. Secondary outcomes include intubation conditions, patient comfort, cough severity, intubation time, and procedure-related complications. The study aims to identify the most effective airway anesthesia technique for maintaining hemodynamic stability and improving patient tolerance during awake fiberoptic intubation.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: Nebulized Lidocaine
Participants allocated to this arm will receive airway topical anesthesia using 4% lidocaine administered via nebulization for 15 minutes before awake fiberoptic intubation. All participants will receive standardized intravenous sedation with midazolam and nalbuphine. Awake fiberoptic intubation will then be performed by an experienced anesthesiologist. Hemodynamic parameters, including heart rate and mean arterial pressure, will be recorded at baseline, during intubation, and at 1, 3, and 5 minutes after intubation. Additional outcomes including intubation time, patient comfort, cough severity, and procedure-related complications will be assessed.
Legemiddel: Nebulized Lidocaine
Participants will receive 4% lidocaine administered via nebulization for 15 minutes before awake fiberoptic intubation to provide topical airway anesthesia and suppress airway reflexes during the procedure.
Eksperimentell: Nerve Block
Participants allocated to this arm will receive airway anesthesia using bilateral glossopharyngeal nerve block and transtracheal block with 2% lidocaine prior to awake fiberoptic intubation. All participants will receive standardized intravenous sedation with midazolam and nalbuphine. Awake fiberoptic intubation will then be performed by an experienced anesthesiologist. Hemodynamic parameters, including heart rate and mean arterial pressure, will be recorded at baseline, during intubation, and at 1, 3, and 5 minutes after intubation. Secondary outcomes including intubation time, patient comfort score, cough severity, and procedure-related complications will also be assessed.
Fremgangsmåte: Nerve Block
Participants will receive airway anesthesia using bilateral glossopharyngeal nerve block and transtracheal block with 2% lidocaine before awake fiberoptic intubation to provide airway anesthesia and suppress airway reflexes during the procedure.
