Effect of Endotracheal Intubation in Lateral Decubitus Position on Intracranial Pressure in Patients Undergoing Spine Surgery- A Case Report

This case report explores the effect of endotracheal intubation in the lateral decubitus position on intracranial pressure (ICP) using non-invasive optic nerve sheath diameter (ONSD) assessment in patients undergoing spine surgery. While ICP monitoring traditionally requires invasive techniques, ONSD measurement via ultrasound has gained popularity as a reliable non-invasive tool for assessing changes in ICP.Endotracheal intubation in lateral decubitus position has been rarely described during spine surgery. This can alter venous return and intracranial dynamics, potentially affecting ICP. The present cases investigate how the combination of the lateral decubitus position and endotracheal intubation influences ONSD and subsequently ICP. Intracranial pressure is a critical factor influencing patient outcomes in neurosurgical procedures, especially in the setting of spinal surgeries that often involves peculiar positioning and airway management. Limited data exists regarding effect of endotracheal intubation in lateral decubitus position on ICP. The present case report aims to explore potential changes in ICP during this procedure and highlight the clinical implications.
