Also known as Inertia Uteri
Uterine atony is a loss of tone in the uterine musculature. Normally, contraction of the uterine muscle compresses the vessels and reduces flow. This increases the likelihood of coagulation and prevents bleeds. Thus, lack of uterine muscle contraction can cause an acute hemorrhage. Clinically, 75-80% of postpartum hemorrhages are due to uterine atony.Source: Wikipedia
Within all the people who go to their doctor with uterine atony, 88% report having spotting or bleeding during pregnancy, 59% report having sharp abdominal pain, and 53% report having pain during pregnancy. The symptoms that are highly suggestive of uterine atony are spotting or bleeding during pregnancy, pain during pregnancy, intermenstrual bleeding, and back cramps or spasms, although you may still have uterine atony without those symptoms.
Patients with uterine atony often receive hematologic tests, urinalysis, complete blood count, radiographic imaging procedure, standard pregnancy test, pelvis exam, ultrasonography and glucose measurement .
The most commonly prescribed drugs for patients with uterine atony include rho(d) immune globulin (rhogam), miconazole topical product, progesterone, carmustine, ferrous fumarate / folic acid / polysaccharide iron complex, valdecoxib (bextra), 5-hydroxytryptophan, docusate / sennosides, usp, calcium polycarbophil (fibercon) and ampicillin .
