[Anesthetic management of MIDCAB in a patient with Wolff-Parkinson-White syndrome].
We experienced the anesthetic management of a minimally invasive direct coronary artery bypass (MIDCAB) in a patient with Wolff-Parkinson-White (WPW) syndrome. A 55-year-old male had chest pain on effort and was diagnosed as having stenosis of the left coronary artery (#6). He was scheduled to undergo MIDCAB. Anesthesia was induced with midazolam 5 mg, fentanyl 300 micrograms, and vecuronium 10 mg and maintained with air-oxygen, propofol, and fentanyl (27 micrograms.kg-1). Diltiazem was continuously infused at a rate of 0.5-1.5 micrograms.kg-1.min-1 throughout the surgery. The hemodynamic parameters were maintained stable and paroxysmal supraventricular tachycardia was not observed during the procedure. We conclude that the administration of propofol and a medium dose of fentanyl is useful for the anesthetic management of MIDCAB in patients with WPW syndrome and that intraoperative administration of diltiazem might be needed to avoid paroxysmal supraventricular tachycardia.
