Harlequin Syndrome Following Regional Liposomal Bupivacaine Use in a Partial Sternectomy.

Harlequin syndrome is a condition in which disruption of the autonomic nervous system results in ipsilateral anhidrosis and pallor of the face. We report the first documented case of Harlequin syndrome following the use of liposomal bupivacaine, in which a patient developed symptoms five hours after a bilateral erector spinae plane (ESP) block with liposomal bupivacaine before partial sternectomy. It is additionally unique as the first report of delayed onset of symptoms.
