Neonatal Jaundice: IAP Guidelines

Appears after 24 hours of life, decreases after 5–6 days, and undetectable after 14 days.

Maximum values seldom exceed 15 mg/dL.

The Indian Academy of Pediatrics (IAP) has released Standard Treatment Guidelines 2022 for Neonatal Jaundice. The lead author for these guidelines Neonatal Jaundice is Dr. Naveen Jain along with co-author Dr. Ravi Sachan and Dr. Praveen Vaenkatagiri. The guidelines come Under the Auspices of the IAP Action Plan 2022, and the members of the IAP Standard Treatment Guidelines Committee include Chairperson Remesh Kumar R, IAP Coordinator Vineet Saxena, National Coordinators SS Kamath, Vinod H Ratageri, Member Secretaries Krishna Mohan R, Vishnu Mohan PT and Members Santanu Deb, Surender Singh Bisht, Prashant Kariya, Narmada Ashok, Pawan Kalyan.

Following are the major recommendations of guidelines:

Severe Jaundice— Hyperbilirubinemia:

Any jaundice visible in first 24 hours of life

Yellow staining of palms and soles or deep yellow appearance (measure bilirubin values using transcutaneous bilirubinometer or laboratory testing of serum sample, when in doubt)

Bilirubin values >95 centile for gestation/weight/age in hours, evaluated on standard charts like the American Academy of Pediatrics (AAP) or National Institute for health and Care Excellence (NICE), UK) charts

Warning signs of encephalopathy such as poor feeding and lethargy

Evaluation for Risk of Hyperbilirubinemia:

Before discharge 24-72 hrs from birth All babies must be evaluated clinically for bilirubin levels while in hospital and before discharge; and confirmed objectively when in doubt, by a transcutaneous bilirubinometer or serum bilirubin plotted on hour specific nomograms. Kramer's Criteria is helpful in clinical assessment of the severity of the jaundice. The clinical assessment requires natural light (can be faulty in hospital lighting). It also depends on experience of personnel and subjectivity of assessment)

Use the hour-specific nomogram to evaluate risk before discharge from birth admission. Babies with values in high-risk zone must be re-evaluated within 24 hours

After discharge (until day 5–6 of life) from hospital

• All babies reviewed within 48 hours and babies with higher risk within 24 hours of discharge for yellow staining of palms and soles or deep yellow appearance (measure values using transcutaneous Bilirubinometer or laboratory testing of serum sample, when in doubt, use specific charts such as AAP or NICE charts to evaluate need for treatment).

• Look for lactation problems (excess weight loss and delayed transition of stool to yellow color), infrequent stool, and urine.

• Exclude early signs of encephalopathy (poor feeding and lethargy)

Close follow-up (within 24 hours of discharge) is warranted in risk groups

BOX 1: Risk groups: Need close attention.

Mother Rh-negative or O group þ Gestation of baby <38 completed weeks þ Lactation not established þ Predischarge bilirubin in high-risk zone (transcutaneous bilirubin >13 mg/dL) þ Cephalohematoma Previous baby with jaundice þ Glucose-6-phosphate dehydrogenase (G6PD) deficiency

History:

Gestational age and postnatal age (in hours)

Birth weight and current weight

Mode and adequacy of feeding

Urine color and number of wet nappies

Passage of meconium and color of stool

Activity and behavior during sleep/waking up

Any abnormal cry or body movements

Any bleeding/bruising

Mother's blood group and baby's blood group

Previous baby with severe neonatal jaundice

Feature of acute bilirubin encephalopathy (hypotonia and hypertonia, lethargy, highpitched cry, poor suck, irritability, seizure, and opisthotonos posture)

Total serum bilirubin (TSB)

Mother and baby's blood group (collect cord blood/venous sample immediately after birth, if mother's blood group is Rh-ve)

Suspected hemolysis: Complete blood count, reticulocyte count, peripheral blood smear, and direct Coombs' test

In areas of high prevalence: Screen for glucose-6-phosphate dehydrogenase (G6PD) deficiency

For prolonged jaundice*: Total and direct bilirubin, thyroid function test, urine reducing substances, and culture. Ultrasound abdomen to exclude biliary atresia. *Prolonged jaundice: Visibly detectable jaundice beyond 2 weeks of age in a term and beyond 3 weeks of age in a preterm infant. Ask for pale stool or yellow urine, check for adequacy of weight gain. Do total and direct bilirubin test.

Hyperbilirubinemia is a potentially treatable condition. It may cause long-term neurodevelopmental impairment, if not treated timely and appropriately.

Early initiation and frequent breastfeeding and/or early use of mother's own milk (MOM) in neonatal intensive care unit (NICU).

Reducing the level of serum bilirubin by intensive phototherapy and/or exchange transfusion. Phototherapy is a noninvasive, cost effective, safe, and easy to use method; it is available at all levels of neonatal healthcare. It should be started (after sending TSB) when jaundice appears within 24 hours and/or involving palm and soles; and if TSB is in range of phototherapy as per AAP or NICE charts. Stop phototherapy, if serum bilirubin level is 2–3 mg/dL lower than the phototherapy range .

Use blue light and appropriate intensity of phototherapy (>30 µW/cm2 per nm) • Light-emitting diode (LED) and compact fluorescent lamps (CFL) most often deliver the required intensity for a long duration. A periodic check of the intensity must be done to ensure efficacy (once in 6 months).

Place phototherapy as close to baby as possible without causing hyperthermia

Expose maximum area of body

Ensure optimal breastfeeding and stool output

Hyperbilirubinemia (as per AAP or NICE charts) not responding to intense phototherapy

Any signs of early encephalopathy (poor feeding/lethargy) in babies with hyperbilirubinemia

Babies with hyperbilirubinemia noted within 24 hours of life, preterm babies, and previous child requiring exchange transfusion or sick babies (sepsis) with hyperbilirubinemia are at risk of developing bilirubin associated neurologic damage at values less than that indicated on standard chart. They must be referred early to centers with facilities for exchange transfusion.

Exchange transfusion is a rapid, invasive, and effective method to reduce serum bilirubin. It is a specialized procedure, performed where facilities and skills are available. If facilities are not available, refer the baby along with mother's blood sample (if mother is not accompanying).

Blood being used must be crossmatched with mother's blood.

For Rh-isoimmunization: O-negative packed cells suspended in AB plasma or O-negative whole blood or Rh-negative baby's ABO group after crossmatch.

For ABO isoimmunization: O group (Rh-compatible) packed cell suspended in AB plasma or O group whole blood (Rh-compatible with baby) after crossmatch.

In other situation, baby's blood group should be used.

Babies who had hyperbilirubinemia must be followed up periodically using developmentscreening tools until school age. The assessments should include early language milestones. Babies who had signs of encephalopathy or required exchange transfusion must have a hearing evaluation for sensorineural hearing impairment by brainstemevoked audiometry before 6 months age.
