Effect of esmolol on the heart rate, arterial pressure and electrocardiographic changes during laryngomicroscopy.


BACKGROUND Laryngomicroscopy causes considerable haemodynamic and ECG changes and therefore requires high doses of anaesthetic agents, which prolong recovery. In this double-blind randomized work, we studied the effect of esmolol, a short-acting beta-adrenergic receptor-blocking agent, on haemodynamic and ECG changes during laryngomicroscopy under… (More)
