Review Case ReportsAntidepressant treatment with MAO-inhibitors during general and regional anesthesia: a review and case report of spinal anesthesia for lower extremity surgery without discontinuation of tranylcypromine.
Monoamine oxidase-(MAO)-inhibitors are a treatment of last resort in treatment resistant depression, which is regarded as a condition of increased psychiatric risk. General and regional anesthesia for elective surgery during use of long-term MAO-inhibitors remains a matter of debate because of an increased risk of drug interactions and decreased sympathetic stability. A series of case reports and new comparative studies reveal the safety of anesthesia/analgesia in non-cardiac surgery without discontinuation of the MAO-inhibitor if best effort is made for maintenance of sympathetic homeostasis and if known drug interactions are avoided. ⋯ No peri- or postoperative complications were encountered. It is concluded that general or regional anesthesia for noncardiac surgery without discontinuation of MAO-inhibitor treatment may be a safe intervention after careful evaluation of an individual's perioperative and psychiatric risk. The increased psychiatric risk in patients treated with MAO-inhibitors outweighs the increased, however manageable, perioperative risk from continuing treatment during surgery.
