inflammation of the muscular and mucosal layers of the uterus.
Metritis is caused by the introduction of infection (usually streptococcal or staphylococcal) into the uterine cavity after abortion or complications in labor. Less often, metritis is a complication of acute diseases, such as tuberculosis or tonsillitis. In the majority of cases it begins with inflammation of the mucosa, called endometritis, but in acute endometritis the inflammatory process almost always extends to the muscular layer, so that metritis proper develops and the entire process acquires the character of metroendometritis. Acute metritis is manifested by elevation of body temperature, general weakness, and headache. The uterus is enlarged and tender. Palpation produces vaginal discharges of pus or of blood and pus.
Acute metritis is treated with rest, cold applied to the lower abdomen, antibiotics, and sulfanilamide preparations. Chronic metritis is treated with physical therapy and health resort therapy.
