The Wolff-Parkinson-White syndrome (WPW syndrome) and its variants are called the preexcitation syndrome. Anesthetic management of the patient with WPW syndrome requires the minimizing or avoidance of tachyarrythmias. Various anesthetic plans are employed for this purpose. For example, N2O, oxygen and narcotic technique, neuroleptanalgesia, deep inhalation anesthesia are included in this category. We have recently anesthetized a patient with preexcitation syndrome, performing continuous epidural anesthesia with 2% lidocaine and single bolus injection of Innovar followed by general endotracheal inhalation anesthesia with enflurane, and our experience suggested that this anesthetic method might be useful for the patients with WPW syndrome and below-lower abdomen operation.
