Abstract
Objective To explore psychological care on changes in auditory evoked potential (AEP) and hemodynamics during anesthetic induction with remifentanil. Methods 30 ASA Ⅰ-Ⅱ patients were divided into study group and conrol group. The study group received psychological care one day before surgery, a intravenous injection of remifentanil of 1μg/kg 4 min before anaesthestic induction, and then a continuous infusion of remifentanil 0.1 μg/kg/min, which was decreased to 0.05μg/kg/min during anesthetic induction; while the control group received esmolol of 300μg/kg/min, which was reduced to 200 μg/kg/min during induction. The medications were terminated 10 min after intubation. AEP, ECC, HR, SBP, and RPP were compared between the two groups and then analyzed statistically. Results AEP did not differ significantly between the two groups at different time points (P>0.05). SBP, HR, and RPP changed slightly in the study group after intubation. Conclusions Psychological care is helpful in making remifentanil more effectively suppress the adverse cardiovascular reactions during intubation.
