Haemodynamic stability
Topical anaesthetic delivered to the mucosal surface of the larynx may encourage greater haemodynamic stability and reduced airway stimulation in patients
- Reduced heartrate vs pre‐induction values
- Reduced cardiovascular response
- Easier intubation vs saline
- Fewer attempts for successful insertion of a laryngeal mask
Topical administration of anaesthetic to the mucosal surface of the larynx, the trachea and carina, or the bronchus can block the airway‐cardiovascular reflexes evoked by mechanical stimulation of the same part of the respiratory tract.
