sher分级( internationa) Grade I: Slignt vaginal bleeding and some uterine irritability are usually present. Maternal blood pressure is unaffected, and the maternal fibrinogenlevel is normal. The fetal heart rate patternis normal Grade Il: Externaluterine bleeding is mild to moderate. The uterus is irritable, and tetanic or very frequent contractions may be present. Maternal blood pressure is maintained, but the pulse rate rate may be elevated and postural blood decreased The fetal heartrate often shows signs of fetal e volume deficits may be present. The fibrinogen level may be compromise. Grade Il: bleeding is moderate to severe but may be concealed. The uterus is tetanic and painful. Maternal hypotension is frequently present and fetal death has occurred. Fibrinogen levels are often reduced to less than 150 mg/dl; other coagulation abnormalities (thrombocytopenia, factor depletion) are present.Sher分级 (international) ➢ Grade I: Slignt vaginal bleeding and some uterine irritability are usually present.
