Background: Use of GlideScope® laryngoscopes and lightwands for tracheal intubation does not require much force. Theoretically, less stimulation can reduce hemodynamic changes during intubation. We investigated the hemodynamic response to tracheal intubation using different laryngoscope types during remifentanil infusion.
Methods: Sixty American Society of Anesthesiologists class I-II patients were compared in terms of tracheal intubation time, hemodynamic changes, and postoperative pharyngeal complications when using a GlideScope®, lightwand, or Macintosh laryngoscope. Propofol and rocuronium were injected and remifentanil was infused for three minutes. Blood pressure and heart rate were measured before and 1, 3, and 5 minutes after tracheal intubation. Patients were assessed for postoperative oral and tracheal bleeding as well as hoarseness, dysphagia, and sore throat.
Results: Intubation time was prolonged in the GlideScope® group. All three groups showed a significant decrease in systolic and diastolic blood pressure 1, 3, and 5 minutes after tracheal intubation. Heart rates increased significantly in all three groups immediately after intubation as well as 1 minute later in the GlideScope® group. However, there were no differences in blood pressure, heart rate, or the occurrence of hoarseness, dysphagia, and sore throat among the three groups.
Conclusions: No differences in hemodynamic change were found among the three different techniques.
