Neurohumorally induced cardiac dysrhythmias during nitrous oxide-oxygen-thiopental anesthesia
Abstract:
Barbiturate, nitrous oxide, and oxygen are commonly used by the oral and maxillofacial surgeon to anesthetize the ambulatory oral surgery patient. The authors report three cases of ventricular dysrhythmia occurring from surgical stimulation during nitrous oxide-oxygen-thiopental anesthesia. These dysrhythmias were most likely mediated via direct neural stimulation of cardiac sympathetic nerves. Concomitant with adrenergic stimulation, a rise in the arterial plasma norepinephrine level was documented, along with an increase in the rate-pressure product. Immediate recognition and treatment of ventricular dysrhythmia is mandatory to preclude further serious cardiovascular complications or death.
