Fetal-maternal haemorrhage is the loss of fetal blood cells into the maternal circulation. It takes place in normal pregnancies as well as when there are obstetric or trauma related complications to pregnancy.
Early clamping of the umbilical cord does not decrease risks and may cause anemia in the baby, and thus is usually not recommended. [2] Active management of the third stage is a method of shortening the stage between when the baby is born and when the placenta is delivered. [15] This stage is when the mother is at risk of having a PPH.
Besides placenta previa and placental abruption, uterine rupture can occur, which is a very serious condition leading to internal or external bleeding. Bleeding from the fetus is rare, but may occur with two conditions called vasa previa and velamentous umbilical cord insertion where the fetal blood vessels lie near the placental insertion site unprotected by Wharton's jelly of the cord.

Chorionic hematoma is the pooling of blood 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 .
Caput succedaneum is a benign neonatal condition involving a serosanguinous (containing blood and serum), subcutaneous, extra-periosteal fluid collection with poorly defined margins caused by the pressure on the presenting part of the fetal scalp by the vaginal walls and uterus as the infant passes through a narrowed cervix during delivery.
Subconjunctival bleeding occurs in about 2% of newborns following a vaginal delivery. The blood accumulates between the conjunctiva and the episclera. Diagnosis is generally based on the appearance of the conjunctiva. [2] The condition is relatively common, [4] and both sexes are affected equally. Spontaneous bleeding occurs more commonly over ...
Some other common factors that can cause cephalohematoma are when using forceps or vacuum-assisted delivery methods, vaginal delivery of large infants, primigravida (the first pregnancy conceived by a pregnant person), when the infant is in a non-ideal position during delivery, and having a prolonged second stage of labor.
Early recognition of this injury is crucial for survival. Infants who have experienced a difficult operative delivery or are suspected to have a SGH require ongoing monitoring including frequent vital signs (minimally every hour), and serial measurements of hematocrits and their occipital frontal circumference, which increases 1 cm with each 40 mL of blood deposited into the subgaleal space.
