Evaluation of Intracranial Pressure Change by Measuring Optic Nerve Sheath Diameter During Lung Recruitment Maneuver in Patients With Acute Respiratory Distress Syndrome: A Prospective Experimental Study
In Brief
A clinical study evaluating The recruitment maneuver for Effect of Recruitment Maneuver on Intracranial Pressure. Completed, enrolled 81 participants across 1 site.
Detailed Summary
Recruitment maneuver is used to reopen atelectasis alveoli. Positive airway pressure applied during the recruitment maneuver may increase intrathoracic pressure, resulting in hemodynamic instability, venous return disorders, and increased intracranial pressure. Our study will examine the effect of recruitment maneuver on intracranial pressure by evaluating Optic Nerve Sheath Diameter change.
Study Details
Timeline
Interventions
In patients with ARDS, 30 cm H2O positive pressure support and 30 seconds recruitment maneuver will be applied. The effect of the recruitment maneuver on intracranial pressure will be investigated by measuring the optic nerve sheath diameter with the help of ultrasonography before and after the recruitment maneuver. Optic nerve diameter will be evaluated with a linear probe on the eyeball before and after the collection maneuver, taking a value of 3 mm from the eyeball.
