Perioperative Management of Antisynthetase Syndrome: A Case Report.

Antisynthetase syndrome is a rare idiopathic inflammatory multisystem disorder, which can lead to serious postoperative complications. Due to its low incidence, there is little literature on its anesthetic management. However, patients with this disease can suffer from serious complications secondary to muscle weakness and respiratory complications. Although the intraoperative and the immediate postoperative periods may be uneventful, complications may appear later. The characteristics of the disease can lead to a misdiagnosis in the case of respiratory acute failure. The objective of this clinical report is to discuss the perioperative management of patients suffering from antisynthetase syndrome, assess the usefulness of postoperative monitoring, and evaluate alternatives that could have been carried out to prevent the fatal outcome reported in this narrative.
