摘　　要：BACKGROUND Rocuronium,a nondepolarizing muscle relaxant,is usually administered during general anesthesia to facilitate endotracheal intubation and keep patients immobile during the surgery.Sugammadex,the selective reversal agent of rocuronium,fully reverses the neuromuscular blockade(NMB)at the end of surgery.Most reports show that sugammadex rapidly achieves a ratio of train-offour(TOF),a quantitative method of neuromuscular monitoring,of 0.9 which ensures adequate recovery for safe extubation.However,very rare patients with neuromuscular diseases may respond poorly to sugammadex.CASE SUMMARY A 69-year-old female presented with abdominal fullness and nausea,and was diagnosed with gastroparesis.She underwent gastric peroral endoscopic myotomy under general anesthesia with rocuronium(0.7 mg/kg).At the end of surgery,sugammadex 3.6 mg/kg was administered when TOF showed 2 counts.Afterward,the TOF ratio recovered to 0.65 in 30 min.She was awake but could not fully open her eyelids.The tidal volume during spontaneous breathing was low.After additional doses of sugammadex(up to 7.3 mg/kg)in the following 3 h,the TOF ratio was 0.9,and the endotracheal tube was smoothly removed.After excluding possible mechanisms underlying the prolonged recovery course,we speculated our patient may have had an undiagnosed neuromuscular disease,hinted by her involuntary movement of the tongue and mouth.Furthermore,her poor renal function and history of delayed recovery from general anesthesia may be related to the long duration of rocuronium.CONCLUSION In our case,both prolonged rocuronium-induced NMB and poor response to sugammadex were noted.To optimize the dose of rocuronium,perioperative TOF combined with other neuromuscular monitoring is suggested.
