The Effect of Video and Traditional Laryngoscopy on Hemodynamic Response in Hypertensive and Normotensive Patients

During endotracheal intubation, it is known that la laryngoscopy has significant effects, such as tachycardia and blood pressure increase, which may be harmful, especially in those with cardiovascular disease. Different studies comparing laryngeal stimulation and there resulting hemodynamic response made with various intubation devices are available in the literature. The investigators planned to work with the hypothesis that endotracheal intubation with videolaryngoscopy would have less hemodynamic response traditional (Macintosh) laryngoscopy and the use of videolaryngoscopy would result in wider vision with less laryngeal stimulation.

About this study

In this study, in a study on endotracheal intubation under general anesthesia, a routine preparation of endotracheal intubation using video laryngoscopy or Macintosh laryngoscopy in adult hypertensive and normotensive patients between 18-75 years old, form will be written and recorded.

Patient age, weight, height, sex, operation, co-morbid conditions and vital findings, measurements used in airway evaluation, initial trial success, laryngoscope using number of procedures, intubation tube number will be recorded.

Statistical analysis was performed using statistical program to compare the hemodynamic response of hypertensive and normotensive patients using videolaryngoscope or Macintosh laryngoscope
