Summary
Brief summary (as posted)
Endotracheal intubation and laryngeal mask are generally applied to secure the airway during general anesthesia. There is a widespread opinion among anesthesiologists that endotracheal intubation increases intracranial pressure. Since there were no non-invasive methods measuring intracranial pressure in the past, adequate studies on this subject could not be done. With this measurement, we aimed to show whether ETT or LMA applications have effects on intracranial pressure.

- description
- 30 patients who will be intubated with a video laryngoscope and who meet the inclusion criteria are randomly selected by lottery method. After obtaining the consent of the patient's family, the patient is taken to the operating room and monitored. 5 minutes after sedation with 1 mg midazolam, the optic nerve sheath diameter of both eyes is measured with a linear ultrasound probe and recorded (T0). 5 minutes after the patient is intubated with a video laryngoscope, the optic nerve sheath diameter of both eyes is measured and recorded (T1). After the patient's extubation at the end of the case, the optic nerve sheath diameter of both eyes is measured and recorded (T2). Vitals (pulse, blood pressure, saturation) involved in T0, T1 and T2 processes are recorded.

- description
- 30 patients who will be intubated with a normal laryngoscope and who meet the inclusion criteria are randomly selected by lottery method. After obtaining the consent of the patient's family, the patient is taken to the operating room and monitored. 5 minutes after sedation with 1 mg midazolam, the optic nerve sheath diameter of both eyes is measured with a linear ultrasound probe and recorded (T0). 5 minutes after the patient is intubated with a normal laryngoscope, the optic nerve sheath diameter of both eyes is measured and recorded (T1). After the patient's extubation at the end of the case, the optic nerve sheath diameter of both eyes is measured and recorded (T2). Vitals (pulse, blood pressure, saturation) involved in T0, T1 and T2 processes are recorded.
