Symptoms of anemia in premature infants?

summary

The average hemoglobin of umbilical cord blood of premature infants was 175g / L ± 16g/L(17.5g/dl ± 6 g / dl), similar to that of term infants. The hemoglobin of premature infants with birth weight of 1.2-2.5 kg was 80-100 g / L (8.0-10.0 g / dl) at 5-10 weeks after birth, and that of premature infants with birth weight of less than 1.2 kg was 65-90 g / L (6.5-9.0 g / dl) at 4-8 weeks after birth. Anemia premature infants without symptoms, good eating, weight gain, some people call it premature physiological anemia, do not need treatment. However, the mechanism of physiological anemia in preterm infants is not the same as that in full-term infants, and the symptoms often appear, so some people think it should be non physiological and need intervention. Let's share my experience with you.

Symptoms of anemia in premature infants?

Anemia symptoms are pale, feeding difficulties, weight loss, shortness of breath, tachycardia, decreased activity, apnea, etc. Edema a few cases have lower limbs, feet, scrotum, facial mild edema.

Indications for blood transfusion in preterm infants: blood transfusion should be based not only on hemoglobin value, but also on gestational age, postnatal age, clinical manifestations, hemoglobin value at birth, blood sample volume and other factors

Although the hematocrit of very small premature infants (< 30 weeks of gestational age) did not increase after blood exchange in the first few days after birth (regular blood collection for laboratory examination, plus a small amount of multiple blood transfusion), HBA replaced HbF and improved oxygen transport.

matters needing attention

Nutrition and feeding of premature infants: at present, people from all walks of life pay more attention to early feeding, which can shorten the time of physiological weight loss, or reduce the degree of weight loss, reduce the incidence of hypoglycemia, and reduce the blood bilirubin concentration. Generally, sugar water will be fed 6-12 hours after birth, and milk will be fed 24 hours after birth. For those with low weight or poor general condition, if cyanosis, dyspnea or operation have occurred, feeding can be postponed and intravenous fluid infusion can be given.
