Zhang, Xuena published the artcileBradyarrhythmia and hypotension during anesthetic induction-reconsideration of nifedipine: a case report., Quality Control of 21829-25-4, the main research area is Bradyarrhythmia; advanced age; anesthesia; case report; hypotension; nifedipine.
Cardiac events sometimes occur during anesthesia and surgery and may be severe or even life-threatening. This report describes a case of severe bradyarrhythmia during anesthetic induction with propofol, midazolam, sufentanil, and vecuronium. The patient took nifedipine sustained-release tablets on the morning of surgery as routine treatment for hypertension, and this medication may have contributed to the bradyarrhythmia. Nifedipine is a calcium channel blocker that can dilate blood vessels, depress the activity of the sinoatrial node, and delay the conduction of the atrioventricular node. Although these effects are not usually significant, they may be enhanced by anesthetics or other concomitant drugs. For patients of advanced age, especially those with autonomic disturbance or cardiac abnormalities, these effects can be remarkable, and discontinuation of nifedipine should be considered.
