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.

Conditions

• Intracranial Pressure Increase
• Supraglottic Airway Device
• Optic Nerve Sheath Diameter

Interventions

Type	Name	Description
OTHER	pLMA: PROSEAL LARYNGEAL MASK, sLMA : SUPREMA LARYNGEAL MASK, I-jel =I-GEL	a SAD was inserted by all anaesthetists participating in the study had at least 3 years experience of airway management and were experienced with both the pLMA, sLMA and I-jel. Inadequate ventilation after two attempts was considered a failed placement, and these patients were excluded, while the practitioner was freed to use an alternative airway device.
