Abstract:
ObjectiveTo observe whether if intravenous infusion of dexmedetomidine in advance can prevent irritation and cough causing by sufentanil.MethodsNinety patients who performed excision of intracranial tumor were divided into observation group and control group by random digits table with 45 cases each.Patients in observation group were intravenously infused 0.5 μg/kg dexmedetomidine for 10 minutes before induction.Patients in control group were intravenously infused 0.9％ sodium chloride for 10 minutes before induction.All the patients were intravenously infused 0.3 μg/kg sufentanil after taking drugs of load dosage in 3 seconds,and the incidence of irritation and cough in 1 minute was observed.The mean arterial pressure and heart rate were recorded before infusing dexmedetomidine or sodium chloride(T0),at the end of infusing dexmedetomidine or sodium chloride (T1),before intubation (T2),1 minute after intubation (T3).ResultsThe incidence of irritation and cough,moderate-severe irritation and cough in observation group [ 24.4％ ( 11/45 ),11.1％ (5/45) ] were lower than those in control group [ 48.9％ (22/45),22.2％ ( 10/45 ) ]with significant differences(P＜ 0.01 ).The mean arterial pressure in control group at T2 was lower than that in observation group [ (71.2 ± 3.5) mm Hg( 1 mm Hg =0.133 kPa) vs.(84.7 ± 4.1 ) mm Hg] with significant difference (P ＜ 0.05 ).The mean arterial pressure in control group at T3 was higher than that in observation group [(96.7 ± 6.4) mm Hg vs.(83.1 ± 5.2) mm Hg] with significant difference(P＜ 0.05).The heart rate at T1,T2,T3 in observation group was lower than that in control group [ (53.2 ± 4.7 ) beats/min vs.(70.4 ± 6.2 )beats/min,(56.3 ± 3.1 ) beats/min vs. (64.7 ± 3.7) beats/min,(59.1 ± 4.8) beats/min vs. (81.5 ± 6.1 )beats/min],and there were significant differences(P ＜0.05).Conclusions Intravenous infusion of dexmedetomidine (0.5 μg/kg) in advance can effectively prevent irritation and cough causing by sufentanil,and can enhance the stability of circulation during intubation.
