Abstract:
Objective To investigate the sedation values of dexmedetomidine combined with midazolam in appendectomy.Methods 90 patients with acute appendicitis were studied prospectively.According to the principle of completely random digital table,all patients were randomly signed into the dexmedetomidine combined with midazolam group,single midazolam group or single dexmedetomidine group.The hemodynamic changes in the three groups were compared.Results There were no significant differences in the three groups in heart rate and mean arterial pressure at t0 (P >0.05).When compared with the single midazolam group or dexmedetomidine group,patients in dexmedeto-midine group got a significant reduction in heart rate at t1 [(79.73 ±10.36)beat/min vs.(93.30 ±19.32)beat/min and (90.85 ±18.23 )beat/min,F =5.796,P =0.004];at t3 [(79.51 ±11.21 )beat/min vs.(87.53 ± 18.35)beat/min and (95.03 ±14.64)beat/min,F =8.006,P =0.001];and at t5 [(79.73 ±12.24)beat/min vs. (91.80 ±17.71)beat/min and (89.62 ±14.26)beat/min,F =5.584,P =0.005];a reduction in heart rate at t2 and t4,though there was no statistical difference (P >0.05);a significant reduction in mean arterial pressure at t1, t2,t3,t4 and t5 (F =8.444,6.591,8.165,17.121 and 6.977,P =0.000,0.002,0.001,0.000 and 6.977);a sig-nificant reduction in visual analogue scales [(3.40 ±1.28 )points vs.(4.50 ±1.81 )points and (4.37 ± 1.71)points,F =4.131,P <0.05 ];a significant reduction in operation duration [(111.17 ±15.77 )min vs. (129.33 ±13.98)min and (132.50 ±14.67)min,F =0.000,P <0.05];and a significant reduction in bleeding vol-ume [(202.47 ±61.07 )mL vs.(246.87 ±52.06 )mL and (241.93 ±58.71 )mL,F =0.006,P <0.05 ]. Conclusion Dexmedetomidine combined with midazolam contributed to maintaining the hemodynamic stable and reducing the operation duration,intra -operation bleeding volume and visual analogue scales.
