Endotracheal Tube Cuff Pressure Protocol to Reduce Dysphagia Following Anterior Cervical Spine Surgery: A Prospective Randomized Pilot Study

Detailed Summary

Anterior cervical spine surgery (ACSS) is one of the most common procedures performed by spinal surgeons. It is associated with a 30-50% risk of developing swallowing difficulties (dysphagia). Although these difficulties usually improve within 6 months, for some it remains a significant and persistent problem. We hypothesize that lowering the cuff pressure will lower the risk of injury to soft-tissues in the neck that are important to swallowing function. Our objective in this study is to demonstrate a lower occurrence of swallowing problems after anterior cervical spine surgery in patients with lower endotracheal tube cuff pressure during surgery. Forty patients will be randomly assigned to a treatment group or control group. The treatment group will have the cuff pressure maintained at 15mmHg during the entire duration of the procedure. The control group will have the cuff pressure monitored without manipulation. After surgery soft-tissue swelling will be assessed on the five routine neck x-rays taken. In addition, 3 questionnaires completed before surgery and at each scheduled follow-up appointment will measure and track changes in swallowing over time and assess the impact of swallowing function on the patient's overall health. The results of this study may show that making a minor, inexpensive change during an operation may lower the risk of swallowing difficulties after a relatively common surgery.
