【 摘 要 】

Sugammadex is a relatively new drug used to reverse the effects of rocuronium, a nondepolarizingmuscle relaxing agent to hasten emergence from general anesthesia. Unlike neostigmineand atropine, its use is not associated with re-curarization or cardiac arrhythmias. Sugammadex carries asmall risk of allergic reactions including anaphylactic shock.We present a case report of a 67 years old woman who underwent an urgent operation for small bowelobstruction. Due to atrial fibrillation (AF) the anesthesiologist administered Sugammadex just beforeskin closure. Soon after the injection, peak inspiratory pressures (PIP) increased precipitously followedby hypotension and increasing tachycardia. For anticipated cardioversion, the chest was exposed andit revealed urticarial. There was severe bronchospasm on auscultation. Treatment of anaphylactic shockwas initiated, the patient improved dramatically and fully recovered.This case is presented to alert practitioners to the importance of a sudden rise in PIP after Sugammadexadministration in the early diagnosis of an anaphylactic reaction, and to suggest that due to the risk ofanaphylaxis, it may be advisable to initiate sugammadex only when the patient can be fully exposedwithout compromising the sterility of the operating field.
