Esophageal pH monitoring risks 24h
Normally esophageal pH monitoring is generally well tolerated. The introduction and passage of the tube through the nose and throat as much produce some discomfort, although the patient is quickly accustomed to this feeling.
The most common risks associated with pH monitoring are minor. During catheterisation nausea, nasal or throat discomfort, irritating cough and sometimes small nosebleeds that usually subside spontaneously may occur.
Moreover, rarely it happens that you can not enter the tube through the nose or the patient is intolerant to it, so the premature termination of the test occurs.
