We have devised a simple method to continuously measure the endotracheal tube cuff pressure
(CP) using an invasive pressure monitoring setup (IPMS), which is used routinely in the
operating room to monitor arterial or central venous pressures. We have previously confirmed
both in vitro and in vivo (previous IRB approved protocol), a clinically applicable
agreement of the IPMS readings with the values obtained from a standard manometer (gold
standard). In the current study, we will prospectively evaluate the relationship between the
patient's head position and CP in patients undergoing otolaryngological surgery and also
measure the oxygen and nitrous oxide saturation in the oropharynx.
- Less than 18 years of age, undergoing otolaryngological surgery with endotracheal
- Patient who is intubated with an uncuffed endotracheal tube.
- Patients who have a limitation for movement of the neck or concerns of the stability
of the cervical spine.
