Objective To explore the Analgesic effect of dezocine combining with different concentrations of sufentanil on patient-controlled intravenous analgesia in patients undergoing cesarean section.Methods 120 patients of cesarean section patients from January 2013 to December 2015 in our hospital were randomly and equally selected in to into group D1,group D2 and group D3,40 cases in each group.Patients in group D1 were given dezocine 0.3mg/kg+sufentanil 1.0μg/kg+tropisetron 10mg,patients in group D2 were given dezocine 0.3mg/kg+sufentanil 1.5μg/kg+tropisetron 10 mg,patients in group D3 were given dezocine 0.3mg/kg+sufentanil 2.0μg/kg+tropisetron 10mg.Visual analogue scale(VAS),ramsay sedation scale(RSS),the number of remedy analgesic medication and side effects were observed and recorded 1,4,8,12,24 and 48 hours after surgery.Results Compared with D2 and D3 group,visual analogue score of D1 group was significantly increased,and the difference were statistically significant(P<0.05).Compared with D1 and D2 group,the incidence of adverse reactions in group D3 was significantly higher than that in group D1 and group D2,and the difference was statistically significant(P<0.05).There was no statistically significant difference in sedation scores among the three groups.Conclusion Compared with other concentrations of sufentanil combined with dezocine,the effect of intravenous patient-controlled analgesia after cesarean section was good with dezocine 0.3mg/kg+sufentanil 1.5μg/kg+tropisetron 10 mg,and the incidence of adverse reactions is low.

Objective To observe the effects of dexmedetomidine combined with propofol on the hemodynamics level in elderly patients undergoing gastroscopy.Methods 68 patients undergoing endoscopy from January 2014 to January 2015 in our hospital were selected and randomly divided into observation group and control group, 34 cases in each group.Propofol anesthesia combined with dexmedetomidine was used in the observation group and propofol anesthesia was used in the control group.The RR ( respiratory rate) and HR ( heart rate) of the two groups were observed before the administration (T0), after the administration (T1), when the gastroscope was inserted (T2), after the examination (T3), 5 min after the examination (T4), MAP (mean arterial pressure) and SpO2(pulse oxygen saturation) were measured.The postoperative consciousness, orientation recovery time and surgical tolerance were compared between the two groups.The anesthetic adverse reactions were recorded during the operation.Results The observation group in T1, T2, T3, T4 time point HR were lower than the control group, and the data remained relatively stable level, the difference was statistically significant (P<0.05).There was no significant difference in consciousness recovery time and recovery time of orientation force between observation group and control group.The tolerance of the observation group was higher than that of the control group, the difference was statistically significant (P<0.05).The total adverse reaction rate of the observation group was 32.35% lower than that of the control group 88.24%, the difference was statistically significant ( P <0.05 ) .Conclusion Dexmedetomidine combined with propofol for the elderly patients with painless gastroscopy , analgesic effect is good, and can better maintain hemodynamic fluctuations, reduce propofol anesthesia adverse reactions, does not Affect the patient's awareness and ability to restore the direction.
