Hemodynamic Response to Tracheal Intubation Using New Airway Intubating Devices

Background: Cardiovascular responses (stress response) to endotracheal intubation have been well documented for direct laryngoscopy and are caused by the noxious stimuli to the oropharyngeal structures, the larynx and trachea. The improved glottic view provided by indirect video laryngoscopy reduces the need for excessive manipulation during intubation.Patients and Methods: 120 adult patients divided into 2 groups each is 60 patients in each group using Storz C-MAC videolaryngoscope in Group 1 and fiberoptic bronchoscopy in Group 2. Intubation time success rate and number of attempts were recorded.Results: There were no significant differences between both groups in demographic data, there was no significant difference in hemodynamic changes (systolic and diastolic blood pressure and heart rate) comparing to baseline value and the other group at the same time and intervals. And the incidence of complications (sore throat mucopharyngeal injury and esophageal intubation).Conclusion: Using C-MAC video laryngoscope and fiberoptic laryngoscopy in patients with anticipated difficult airway are comparable as regards hemodynamic response and incidence of complication during endotracheal intubation.
