Background: Sugammadex is a new reversal agent for nondepolarizing neuromuscular blockade. We conducted the randomized clinical study to compare the recovery between sugammadex alone and combined use of sugammadex and neostigmine.

Methods: Forty adult patients were randomly allocated to Group S (n=20) or Group SN (n=20). General anesthesia was induced and maintained with propofol and remifentanil. The patients were intubated without neuromuscular blockers. After the stabilization of TOF Watch SX® acceleromyography as control, rocuronium 0.6 mg/kg was administered to patients in both groups. The patients in Group S received sugammadex 1.0 mg/kg and those in Group SN received sugammadex 0.5 mg/kg, neostigmine 0.04 mg/kg and atropine 0.02 mg/kg five minutes after rocuronium administration. The cost of reversal and recovery time were measured in both groups.

Results: We analyzed the data of 36 patients (n=18 in each group). The T1/control ratios were significantly higher in Group SN than in group S at 5, 10 and 15minutes after administration of reversal agents. The TOF ratios were significantly higher in Group SN than in group S at 10 and 15minutes after administration of reversal agents. The 90% recovery time of TOF ratio in Group SN was significantly shorter than that in Group S. The cost of reversal was significantly smaller in Group SN than in Group S.

Conclusions: By partially substituting sugammadex with neostigmine, we can attain faster recovery from rocuronium-induced profound neuromuscular blockade.
