High thoracic/low cervical, long‐term intrathecal (IT) infusion of bupivacaine alleviates “refractory” pain in patients with unstable angina pectoris: Report of 2 cases

Abstract

I.t.-bupivacaine infusion may alleviate "refractory" pain in patients with unstable angina pectoris when epidural bupivacaine failed to do so. Its use is apparently limited by the IT-bupivacaine critical dosage (in these patients = 1.0-1.5 mg/h).
