Objective To investigate the effect of different concentrations of sevoflurane inhalation combined with pro?pofol anesthesia on rocuronium pharmacodynamics. Methods Sixty-seven patients, who underwent elective abdominal op?eration in Tianjin Medical University General Hospital from Nov. 2014 to Feb. 2015, were randomly allocated to three groups:propofol combined 0.5 minimum alveolar concentration (MAC) end-tidal concentration of sevoflurane (group Ⅰ, 24 cases), propofol combined 0.75 MAC end-tidal concentration of sevoflurane (group Ⅱ, 20 cases) and propofol combined 1 MAC end-tidal concentration of sevoflurane (groupⅢ, 23 cases). All those patients were given midazolam 0.05 mg/kg, sufen? tanil 0.3μg/kg, etomidate 0.3 mg/kg for anesthesia induction. Rocuronium was given through the T1 mode of Closed-loop muscle relaxant infusion system and infused by 2ED95(0.6 mg/kg). The following variables were recorded:average consump?tion dosage of rocuronium, recovery index, averaged consumption dosage of propofol and remifentanil. Results The aver?aged consumption dosage of rocuronium was decreased in the three groups in turn[(9.71 ± 2.38 vs 7.50 ± 0.98 vs 6.90 ± 1.14)μg·kg-1·min-1,F=18.562,P<0.05]. There was no significant difference in recovery index between the three groups [(8.92± 2.62 vs 8.95 ± 2.58 vs 10.30 ± 3.65)min,F=1.577, P>0.05]. The average consumption dosage of propofol and remifentanil were lower in groupⅢthan those of groupⅠand groupⅡ(P<0.05). Conclusion High concentration of sevoflurane can enhance neuromuscular blockage effect of rocuronium, and decrease the consumption dosage of propofol and remifentanil.
