The level of pain in acute gastroenteritis is generally divided into ten levels clinically: levels one to three are mild, four to six are moderate, and seven to ten are severe. This classification is mainly based on the patient's expression and self-perceived intensity of pain. In cases of acute gastroenteritis, there is often the possibility of experiencing spasms, or pain stimuli might trigger inflammatory infections. Generally, the pain is often above level eight. However, if there is mild pain, or it does not accompany fever, it is usually around level one to three. Therefore, once a patient experiences abdominal pain, an intramuscular injection of scopolamine butylbromide can be used to relieve the pain and help the patient stabilize.
