Low-dose Bupivacaine–Fentanyl Spinal Anesthesia for Lower Extremity Surgery in a Nonparturient with Eisenmenger's Syndrome

Perioperative mortality in patients with Eisenmenger's syndrome is very high, particularly following cesarean section. This case report describes the successful use of low-dose bupivacaine-fentanyl spinal anesthesia for lower extremity surgery in a nonparturient with Eisenmenger's syndrome. A 21-year-old woman with Eisenmenger's syndrome was scheduled to have a fibular head tumor excision. After placement of routine monitor and an arterial line, we inserted an epidural catheter at the L3-L4 interspace to cover a potential inadequate block and then we administered 6 mg of hyperbaric bupivacaine 0.5% with 20 mg of fentanyl intrathecally via a 27-gauge needle at the L4-L5 interspace. There were no hypotension, respiratory depression, hypoxemia, and other severe hemodynamic alterations. No drug was administered via the epidural catheter in the 2-hour operative period and the postoperative course was uneventful. Therefore, we propose that intrathecal opioids combined with local anesthetics may be an alternative anesthetic method in patients with Eisenmenger's syndrome.
