White Cover & Massage Effects on Bilirubin and Phototherapy in ABO-Incompatible Newborns

The Effect of White Cover and Massage Application on Bilirubin Levels and Duration of Phototherapy in Newborns With ABO Incompatibility Receiving Phototherapy

This study aims to examine the effect of white cover and massage application on bilirubin levels and phototherapy duration in newborns with ABO incompatibility receiving phototherapy.

Hyperbilirubinemia is a common problem seen in the neonatal period characterized by yellow staining of the skin and sclera, causing an increase in total serum bilirubin >5 mg/dl. Neonatal jaundice is observed in 60% of term newborns and 80% of preterm newborns. Hyperbilirubinemia is usually physiologic and disappears within a few days. If jaundice becomes severe and pathologic hyperbilirubinemia occurs, it can lead to kernicterus (bilirubin accumulation in parts of the brain) or death.Therefore, any infant with hyperbilirubinemia with elevated serum bilirubin levels requires serious attention and treatment.

ABO incompatibility is a cause of indirect hyperbilirubinemia leading to pathologic jaundice. Newborns with ABO incompatibility tend to have higher bilirubin levels due to impaired bilirubin excretion during the neonatal period. ABO incompatibility is observed in approximately 25% of mother-infant pairs. ABO incompatibility may develop when the mother's blood type is O and the baby's blood type is A or B. In ABO incompatibility, maternal anti-A or anti-B antibodies cross the placenta and bind to A/B antigens on the surface of fetal erythrocytes. Antibody-coated erythrocytes are destroyed in the reticuloendothelial system. Bilirubin increases as a result of heme catabolism that is released with the destruction of erythrocytes, and this is reflected in the clinic as neonatal jaundice. In the presence of ABO incompatibility, early screening and close follow-up of newborns in terms of development of hyperbilirubinemia is very important. Traditional treatment modalities for jaundice due to ABO incompatibility are phototherapy and exchange transfusion.

The primary treatment of neonatal jaundice is phototherapy. The efficacy of phototherapy depends on the phototherapy light source, light intensity, the distance between the phototherapy light and the newborn, and the body surface area exposed to light. Phototherapy has potential side effects such as hyperthermia, dehydration, diarrhea, bronze baby syndrome and skin burns in newborns. Therefore, the use of phototherapy should be minimized and solutions should be found to shorten the duration of phototherapy. To increase the effectiveness of phototherapy treatment, a reflective material can be added to the phototherapy. White fabric that can be used as a reflector can reflect the scattered phototherapy light. When fabrics made of reflective materials are hung on the phototherapy device, they can capture light that may be scattered from the baby to the environment and reflect the light back to the baby. The white fabric can increase the irradiance and thus increase bilirubin conversion. Bilirubin is excreted from the body through feces. Removal of bilirubin from the body reduces jaundice. Massage decreases bilirubin levels by increasing the frequency of bowel movements in newborn babies.
