Possible mitigation of rocuronium-induced anaphylaxis after administration of sugammadex

Sir, We describe a case of rocuronium-induced anaphylaxis, which was possibly mitigated after administration of sugammadex. A 61-year-old woman (45 kg, 155 cm) was scheduled to have bone cementoplasty for pain reduction in relation to bone metastasis of a thyroid cancer. She previously had multiple thyroid surgeries without any allergy report and a history of hypertension. Her medication included propranolol, L-thyroxine, and opioids for chronic pain.
