Haemodynamic response to orotracheal intubation: direct laryngoscopy versus fiberoptic bronchoscopy
Keywords:Fiberoptic Bronchoscope, direct laryngoscope,, orotracheal tube, Hemodynamic measurement
Background and Objectives: The cardiovascular response to laryngoscopy and endotracheal intubation causes a reflex increase in sympathetic activity that may result in hypertension and tachycardia the extent of reaction is affected by the technique of laryngoscopy and the use of instruments like direct laryngoscope and fiberoptic bronchoscope. This study aimed to compare the hemodynamic responses to orotracheal intubation via fiberoptic bronchoscopy versus direct laryngoscopy in patients under general anesthesia.
Methods: : Prospectively120 patients American Society of Anesthesiologist Physical status �-� were collected in Sulaimani Teaching Hospital from the first of May to 31st. July 2008 and categorized into two groups equally. Group A 60 cases intubated by direct laryngoscopy and group B 60 cases intubated by Fiberoptic Bronchoscopy Blood Pressures and Heart Rates were recorded before induction (baseline), immediately after induction, at the time of intubation and every 2 minutes of the operation.
Results: After intubation systolic, diastolic blood pressure and heart rate increased significantly (p<0.05) in both groups in compared to post-induction values but there were no significant increase in blood pressure if compared to base line values only significant increase in heart rate.
Conclusions: The fiberoptic bronchoscopy had the same hemodynamic responses to orotracheal intubation compared to the direct laryngoscopy.
