BackgroundThe aim of this study was to evaluate the effects of remifentanil in comparison with those of fentanyl on the hemodynamic response to orotracheal intubation.MethodsExperimental Designprospective comparative and randomized study.Settingoperating room in a neurosurgery department at University.Patients50 patients, ASA I or II with age ranging from 32 to 64 years were divided in two groups randomly.Interventions25 patients received fentanyl as single bolus dose of 2.0 micrograms/kg and atropine 0.01 mg/kg i.v. as premedication while the remainders received atropine 0.01 mg/kg i.v. and remifentanil 0.2 microgram/kg/min as infusion. All patients were induced with propofol 2.0 mg/kg and cisatracurium 0.15 mg/kg for muscle relaxation and were intubated 4 min after induction of anesthesia.MeasurementsHeart rate, SAP, DAP, MAP and RPP were recorded at different times: baseline, induction, intubation, 1, 2, 3 and 4 min after intubation; ECG and pulsoximetry were monitored continuously. Statistical analysis was carried out using ANOVA for repeated measures and Bonferroni t-test a value of p < 0.05 was considered to be significant.ResultsSignificant increases in PAS were recorded, at intubation and at 1 min after in patients treated with fentanyl; in the remifentanil group significant decreases in SAP at induction and at 4 min after intubation were recorded. HR increased significantly at intubation and at 1, 2 and 3 min after in the fentanyl group. RPP showed a significant decrease at induction in the remifentanil group and significant increases at intubation and at 1, 2 and 3 min after in patients treated with fentanyl.ConclusionIn conclusion remifentanil was found to properly control the hemodynamic response to intubation in comparison with fentanyl.
