What does the examination item of hemolytic disease of newborn have?

summary

Hemolytic disease of the newborn refers to the blood group antibody produced in the mother's body that does not match the fetal blood group antigen due to the blood group incompatibility between the mother and the child. This kind of antibody enters into the fetal body through the placenta, causing homologous immune hemolysis. The blood group incompatibility between Rh blood group system and ABO blood group system is common. What does the examination item of hemolytic disease of newborn have? Next, I'd like to share my views with you.

What does the examination item of hemolytic disease of newborn have?

Blood biochemical examination: red blood cells decreased, hemoglobin decreased, reticulocytes increased significantly, and nucleated red blood cells were seen in the smear. When the white blood cell count was calculated together with nucleated red blood cells, it could be greatly increased. These hemogram changes also varied with the degree of hemolysis.

Blood group test: when the Rh blood group of mother and infant is incompatible, it is possible to use horse serum to identify ABO blood group. Because horse is stimulated by human red blood cell surface antigen, when it produces anti-A (b) antibody, it also produces anti IgG antibody. Therefore, when it is found that there is unexplained doubt, it should think of the possibility of this disease and use human serum to identify ABO blood group.

Specific antibody test: there are immune antibodies, blood jaundice index increases, bilirubin increases, due to different operation methods, the results can be more than three times different, urine, feces, urine and bilinogen excretion increases, when the bile duct is blocked by bile embolus, stool can be gray, Urine Bilirubin, ABO hemolytic disease, erythrocyte acetylcholinesterase activity decreased significantly, Plasma albumin, prothrombin and fibrinogen may be decreased, which can contribute to bleeding symptoms. Severe patients can use thrombocytopenia, prolonged bleeding time, poor blood clot contraction, and a few patients have DIC.

matters needing attention

The earlier breast-feeding after birth, the better, generally about half an hour after birth. If the mother did not secrete milk, but also try to let the newborn sucking nipple, in order to promote milk secretion. Yogurt is rich in bifidobacteria, which can promote gastrointestinal peristalsis and promote the emptying of intestinal metabolic waste.
