About this study

The maintenance of airway opened is one of the main responsibility of the anesthetist. Intubation procedure during anesthesia application benefits such as airway opening, airway and breathing control, aspiration hazard, respiratory effort and dead space reduction, surgical comfort and airway control during resuscitation. Laryngoscopy and tracheal intubation increases in heart rate, blood pressure and the intraocular pressure. The sympathetic-adrenal activity caused by the stimulation of the laryngeal and tracheal tissues is responsible for these negative effects. Endotracheal intubation with videolaryngoscopy is an alternative method used in airway management. Laryngoscopy and tracheal intubation under general anesthesia and laryngeal mask and airway control techniques cause different hemodynamic and catecholamine levels.

Treatment and study plan

Direct Laryngoscope

Device

Endotracheal intubation was applied by anesthesiologist wtih direct laryngoscope. SAP (systolic arterial pressure), DAP (diastolic arterial artery pressure), MAP (mean arterial pressure) were measured before and 5 minutes after intubation, , Heart rate (HR), SPO2 (oxygen saturation by pulse oximetry), PI (perfusion index), and intraocular pressure values measured by the eye clinician using the device.

C-MAC videolaryngoscope

Device

Endotracheal intubation was applied by anesthesiologist wtih direct laryngoscope. SAP (systolic arterial pressure), DAP (diastolic arterial artery pressure), MAP (mean arterial pressure) were measured before and 5 minutes after intubation, , Heart rate (HR), SPO2 (oxygen saturation by pulse oximetry), PI (perfusion index), and intraocular pressure values measured by the eye clinician using the device.

McGrath videolaryngoscope

Device

Endotracheal intubation was applied by anesthesiologist wtih direct laryngoscope. SAP (systolic arterial pressure), DAP (diastolic arterial artery pressure), MAP (mean arterial pressure) were measured before and 5 minutes after intubation, , Heart rate (HR), SPO2 (oxygen saturation by pulse oximetry), PI (perfusion index), and intraocular pressure values measured by the eye clinician using the device.

    The relevant values will be measured in the determined time.

  4. heart rate

    Time frame: From beginning of Anesthesia to 10th minute of surgery

    The relevant values will be measured in the determined time.

  5. peripheral oxygen saturation

    Time frame: From beginning of Anesthesia to 10th minute of surgery

    The relevant values will be measured in the determined time.
