Measurement tool helps reduce over-inflation of safety device on breathing tubes used during GA, decreases sore throats and complications
A measurement tool should be used to reduce overinflation of a device, located on breathing tubes, that protects the patient's airway during general anesthesia to help prevent complications such as sore throat, according to results of a quality improvement initiative presented at the virtual American Society of Anesthesiologists’ Anesthesia Quality and Patient Safety Meeting.
To prepare a patient for general anesthesia, the anesthesiologist places a breathing tube in the trachea (windpipe). Most breathing tubes have a tracheal cuff, which is a balloon that surrounds part of the tube and is inflated to seal and protect the airway during the procedure and to maintain the airflow for ventilation. Quantitative measurement of cuff pressures is not standard at most institutions in the United States. Instead, anesthesiologists often press the cuff between their fingers to check the inflation. This leads to overinflation of the cuff more than half of the time, which increases the risk of a sore throat, cough or injury to the patient’s airway. To help reduce overinflation and prevent complications, the researchers implemented a quality initiative using a quantitative pressure-measuring device called a manometer.
“Similar to checking the pressure of a car’s tires before a road trip, tracheal cuff pressures should be accurately checked using a manometer for each patient having a surgical procedure under general anesthesia,” said Mark Zimmer, B.S., a medical student at UT Southwestern Medical Center, Dallas. “Educating anesthesiologists on how to use the manometer will help to improve technique and the practice of breathing tube placement and tracheal cuff inflation, which has the potential to positively impact outcomes and reduce complications for patients.”
