I am a new grad nurse and a few of my patients have gotten simethicone for gas pain, both in my 5 months as a nurse as well as when I was a student. The other day my patient had excruciating gas pain, and had just had a BM an hour before so he wasn't constipated. I asked the doctor what she thought about giving him simethicone. She told me no because research shows that simethicone does not work. I tried to find the research supporting this but couldn't find it. Has anyone else heard this recently? What else could be done to relieve his gas pain? This patient is a chronic care patient and immobile so ambulating is not an option and he eats solely via gtube feeds so I can't encourage a different diet.
