Objective To evaluate the effect of remifentanil on mean arterial pressure (MAP), heart rate (HR) and QTc interval during tracheal intubation of general anesthesia patients. Methods Seventy-five ASA Ⅰ -Ⅱ grade patients were selected and allocated to receive either saline (group C), remifentanil 0.50 μg/kg (group R1) or remifentanil 0.75 μg/kg(group R2) by random digits table with 25 cases in each, they were administrated as a bolus intravenous, followed by a continuous infusion at 0.10 μg/ (kg·min), 1 min before laryngoscopy. All patients received fentanyl 3 μg/kg,propofol 1.0 - 1.5 mg/kg and vecuronium 0.1 mg/kg. The ECG.MAP and HR were recorded prior to induction of anesthesia (T0), 2 min following the start of drug intravenous of fentanyl and propofol with vecuronium (T1), 1 min following remifentanil or saline (T2), before laryngoscopy(T3), 30 s (T4), 2 min (T5) and 4 min (T6) after intubation. Results The QTc interval was significantly prolonged immediately following intubation in group C and group R1, but it remained stable in group R2, compared with the QTc interval just before laryngoscopy. In group R2, QTc interval was significantly shorter at T4-T6 compared to group C(P< 0.05 or < 0.01). QTc interval significantly increased from baseline at T4 in group R1 and T4-T6 in group C (P< 0.05 or < 0.01). The number of patients with QTc interval > 440 ms were significantly greater immediately following tracheal intubation in group C than that in group R2 [44% (11/25) vs. 12% (3/25)] (P < 0.05). Conclusions QTc interval increases following tracheal intubation during induction of anesthesia using fentanyl and propofol. Intravenous of remifentanil attenuates the QTc interval prolongation associated with tracheal intubation. In addition, remifentanil decreases the hemodynamic responses to tracheal intubation.

The concentrations of borneol in the serum and brain tissue of rats were determined by gas chromatography. Using brain tissue as a relatively independent system, PHARMFIT and PCNONLIN softwares are applied for the kinetic analysis of the infracorporal process of borneol in order to find out and compare the pharmacokinetic characteristics of borneol in the brain and serum. The results showed that borneol was absorbed very rapidly in the gastrointestinal tract and readily permeates the blood-brain barrier into brain tissue. There was a higher specific value of borneol concentration in the brain and serum. Moreover, the half life of distribution phase of borneol in the brain was three times higher than that in the serum. But the constants of elimination rate of borneol in the brain and serum decreased simultaneously and parallelly, hence the accumulation of borneol in brain will not be found.
