Initial Increase in Cuff Pressure in Anterior Cervical Spinal Surgery

When the retractor blades oped and is positioned to provide the surgical access in the anterior cervical spine surgery, it cause the trachea to deviate laterally and pose pressure on the tissue between the retractor and the trachea. This is convincible as revealed by the increase of cuff pressure of endotracheal tube. The study aims to investigate differences in the increase of cuff pressure after retractor is positioned between nasotracheal and orotracheal intubation.
