Objective. To compare the effects of alfentanil and esmolol on hemodynamic and catecholamine responsee to tracheal intubation.Mahods. Thirty-five adult patients were randomly allocated to one of three groups, Group A (control group), Group B (esmolol groap) and Group C (alfentanil group). The patients received either 2 mg/kg esmolol (in Group B) or 30μg/kg alfentanil (in Group C) before intulmtion. Tracheal intubation was performed with 4 mg/kg thiopental and 0. 1 mg/kg vecuronium and 3% isoflurane. Systolic blood pressure(SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), heart rate (HR), norepinephrine(NE),epinephrine(E) and dopamine (DA) were measured before and after intubtttion.Results.The control group had a baseline SBP of 149±23 mmHg while Groups B,C had a baseline SBP of 148±23,and 150±21mmHg,respectively(P>0.05),Three min after tracheal intubation,the control group SBP increased to 160±30mmHg and Group B remained at the baseline level ,147±5mmHg,and Goup C significantly decreased to 91±22mmHg(P<0.01).Two min after intubation HR in Group B increased significantly but 3 min after intubation HR in Groups B and C were significantly lower than that of control group(P<0.05).NE in Groups A and B increased significatly to 5.75±3.51 and 6.75±3.30nmol/L 3 min after intubation(P<0.01).In Group C,3min after intubation NE was not significantly different from the baseline but E becreased significantly(P<0.01).Conclusion.2mg/kg esmolol can moderate the hemodynamic response to tracheal intubation to a certain extent and 30μg/kg alfentanil can completely attenuate the hemodynamic and catecholamine responses.
