Antibiotics have been used to prevent and treat these infections—however, the misuse of antibiotics is a serious problem for global health. [2] It is recommended that guidelines be followed that outline when it is appropriate to give antibiotics and which antibiotics are most effective. [2]
Ultrasound showing a subchorionic hemorrhage [1] Chorionic hematoma is the pooling of blood ( hematoma ) between the chorion , a membrane surrounding the embryo , and the uterine wall . [ 2 ] It occurs in about 3.1% of all pregnancies , [ 2 ] it is the most common sonographic abnormality and the most common cause of first trimester bleeding .
Retained placental tissue and infection may contribute to uterine atony. Uterine atony is the most common cause of postpartum hemorrhage. [13] Trauma: Injury to the birth canal which includes the uterus, cervix, vagina and the perineum which can happen even if the delivery is monitored properly. The bleeding is substantial as all these organs ...
Risks of retained placenta include hemorrhage and infection. After the placenta is delivered, the uterus should contract down to close off all the blood vessels inside the uterus. If the placenta only partially separates, the uterus cannot contract properly, so the blood vessels inside will continue to bleed. A retained placenta thereby leads ...
Normally the maternal circulation and the fetal circulation are kept from direct contact with each other, with gas and nutrient exchange taking place across a membrane in the placenta made of two layers, the syncytiotrophoblast and the cytotrophoblast. Fetal-maternal haemorrhage occurs when this membrane ceases to function as a barrier and ...
Distal lobes are connected by a placental artery and vein extending from the main placenta, which tends to be centrally located and is the largest in mass. [20] At the time of contraction or delivery the connecting placental arteries and veins may rupture resulting in significant haemorrhaging. Incidences of vasa previa and haemorrhaging in the ...
Risks of retained placenta include hemorrhage and infection. If the placenta fails to deliver in 30 minutes in a hospital environment, manual extraction may be required if heavy ongoing bleeding occurs. Very rarely, a curettage is necessary to ensure that no remnants of the placenta remain (in conditions with very adherent placenta, placenta ...
Adrenal hemorrhage characteristic of the Waterhouse–Friderichsen syndrome has been identified in several autopsies of patients who died of sepsis secondary to capnocytophaga canimorsus infection. [8] Viruses may also be implicated in adrenal problems: Cytomegalovirus can cause adrenal insufficiency, [9] especially in the immunocompromised.
