Outcome Measures

Primary Outcomes (2)

  • Hyperbilirubinemia

    Investigators will measure the transcutaneous bilirubin level on the second and seventh day of life and plot the record on the nomograph. The record above the 95th percentile will be taken as considerable hyperbilirubinemia and then the baby will be investigated for total serum bilirubin measurement if needed to declare hyperbilirubinemia. The outcome will be classified as hyperbilirubinemia and non-hyperbilirubinemia.

    1 week since birth

  • Transcutaneous bilirubin level

    Infant's skin bilirubin level on the chest measured using a non-invasive devise called Drager meter. It will be measured in milligram per decilitre or micromole per liter. This outcome will be measured as a continuous outcome.

    1 week of life (after birth)

Secondary Outcomes (7)

  • Preterm birth

    within two days of birth

  • Number of participants with Initiation of labor

    within two days of birth

  • Mode of birth checklist

    within two days of birth

  • Birth weight

    within two days of birth

  • Apgar scores

    within two days of birth

  • +2 more secondary outcomes

Other Outcomes (3)

  • Number of participants with Skin rash

    From initiation of the intervention until 1 week postpartum

  • Number of participants with Diarrhea

    From initiation of the intervention until 1 week postpartum

  • Number of participants with Abdominal bloating

    From initiation of the intervention until 1 week postpartum
