Figure 2.

Changes in the HR of the patients receiving Dex or Rem during intubation. Hemodynamic parameters were analyzed at the baseline (preanesthetic preparation), at infusion (immediately prior to fiberoptic intubation), at intubation and at 1 and 5 min after tracheal intubation. No statistically significant differences were observed in the HR at the five points between the two groups. Data are expressed as the mean ± standard error of the mean. HR, heart rate; Dex, dexmedetomidine; Rem, remifentanil.
