Effect of Different Supralottic Airway Devicess on Optic Nerve Sheath Diameter

Completed

• Conditions: Supraglottic Airway Device; Optic Nerve Sheath Diameter; Intracranial Pressure Increase

• Registration Number: NCT05499754
• Lead Sponsor: Zonguldak Bulent Ecevit University

Brief Summary

Direct laryngoscopy and tracheal intubation are associated with increases in intraocular pressure (IOP), intracranial pressure (ICP), heart rate (HR), and blood pressure. The use of supraglottic airway devices (SADs) are known to be beneficial in overcoming the disadvantages of laryngoscopy and tracheal intubation, especially ocular and pressure stress responses. In recent years, it has been reported that ultrasonographic measurement of optic nerve sheath diameter (ONSD) can be used in the diagnosis of increased ICP. The aim of our study is to compare the effects of Proseal laryngeal mask airway (pLMA), Suprem laryngeal mask airway (sLMA) and I-gel on hemodynamic response and ONSD during insertion in adult patients.
