SF 6 is used as a contrast agent for ultrasound imaging. Sulfur hexafluoride microbubbles are administered in solution through injection into a peripheral vein. These microbubbles enhance the visibility of blood vessels to ultrasound.F 6 is used as a contrast agent for ultrasound imaging.

Once constipation (no bowel movement) has gone on for some time, the result can be what is known as an impacted bowel (sometimes called fecal impaction). Essentially, this means that a large lump of dry, hard stool is stuck inside your rectum.
If it is a major abdominal surgery, of course you will not hear any bowel sounds immediately post op. And you do not need to call the doctor. They don't expect to hear any at first. If it is some other surgery, it depends, but probably will hear bowel sounds. Please chart what you hear (or don't hear). If you auscultate and do not hear bowel sounds, then chart that they are absent, not hypoactive. leslie :-D and RN1982 like this.
