Kangaroo Mother Care (KMC) - Viva Notes

1. Definition

• Continuous skin-to-skin contact between mother and baby
• Exclusive breastfeeding
• Early discharge from hospital with follow-up support
• Family support in caregiving

2. History / Origin

• Introduced in Bogota, Colombia in 1979 by Drs. Hector Martinez and Edgar (Edzar) Rey
• Developed as a response to high infection and mortality rates due to overcrowding in hospitals and shortage of incubators
• Since adopted globally, especially in the developing world

3. Four Essential Components (BSAS)

4. Eligibility / Indications

• Stable newborns weighing < 2000 g (LBW and preterm)
• Baby must be clinically stable (no active infection, no respiratory distress requiring oxygen, no IV lines that cannot be managed in KMC position)
• Can be practiced at facility AND at home

5. KMC Position (How to Position)

1. Baby dressed in nappy, cap, and socks only (chest bare)
2. Placed vertically/upright, prone on mother's chest, between the breasts
3. Head turned to one side (to keep airway clear), slightly extended
4. Frog-like position - legs and arms flexed
5. Baby's abdomen at level of mother's epigastrium
6. Baby secured with a cloth/binder/shawl - firm enough to not slip, loose enough to breathe
7. Mother wears a front-opening garment over the baby

6. Temperature Maintenance

• Room temperature maintained at 25-28°C
• KMC provides thermoregulation through heat transfer from mother's skin
• Prevents hypothermia without an incubator
• Baby's temperature should be maintained at 36.5-37.5°C

7. Duration

• KMC should be provided continuously 24 hours a day (day and night)
• Minimum recommended: 6-8 hours per day if continuous KMC is not possible
• Continue until baby no longer tolerates KMC (baby becomes restless, tries to get out of position)
• Generally continued until baby reaches ~2500 g or 40 weeks corrected gestational age

8. Benefits of KMC

For the Baby:

• Thermoregulation - prevents hypothermia
• Reduces mortality in LBW/preterm infants
• Reduces infection rates (especially nosocomial infections)
• Promotes breastfeeding and weight gain
• Stabilizes heart rate, respiratory rate, and oxygen saturation
• Reduces apneic episodes
• Analgesic effect - reduces procedural pain
• Improved neurodevelopmental outcomes
• Reduces risk of hypoglycemia
• Promotes bonding between mother and baby

For the Mother:

• Promotes lactation and breast milk production
• Improves maternal confidence and bonding
• Reduces maternal anxiety and depression
• Facilitates early hospital discharge

For the Health System:

• Cost-effective - reduces need for expensive incubator care
• Reduces hospital stay
• Reduces hospital-acquired infection burden

9. Contraindications

• Clinically unstable baby (severe respiratory distress, active sepsis, surgical conditions)
• Baby requiring continuous invasive monitoring that prevents KMC position
• Mother unable to provide KMC (critically ill, post-operative, etc.)
• Note: A father or other family member can substitute if mother is unavailable

10. Feeding in KMC

• Exclusive breastfeeding is the goal
• Breastfeed on demand, at least every 2-3 hours
• If baby cannot suck: expressed breast milk via cup, spoon, or paladai
• If mother's milk is unavailable: donor human milk, then formula as last resort
• Do NOT discharge if baby is not feeding well

11. Discharge Criteria from KMC

• Baby is feeding well (breastfeeding established)
• Adequate weight gain (at least 15-20 g/kg/day)
• Maintains body temperature in KMC position
• Mother is confident and able to provide KMC at home
• No acute illness

12. KMC in the Indian Context (NHM / RMNCHA+N)

• Kangaroo Mother Care is a nationally recommended intervention under India's Newborn Action Plan (INAP)
• Part of Facility Based Newborn Care at district level SNCUs (Special Newborn Care Units)
• Listed as an Essential [E] intervention at the Health Facility level (alongside NBSU at block level, SNCU at district level)
• Included in Essential Newborn Care (ENC) package
• Part of management of neonatal hypothermia along with infection prevention, cord care, and breastfeeding promotion
• Mentioned alongside antenatal corticosteroids, Vitamin K injection, and gentamicin as newer interventions to reduce newborn mortality

Care of Low Birth Weight (LBW) Baby - Viva Notes

1. Definition

• LBW: Birth weight < 2500 g (up to and including 2499 g)
• Measured preferably within the first hour of life, before postnatal weight loss occurs (WHO/International agreement)
• Birth weight is the single most important determinant of a baby's chances of survival, healthy growth and development

2. Classification by Birth Weight

3. Classification by Gestational Age

4. Two Main Groups of LBW Babies

5. Epidemiology (Key Numbers for Viva)

• India: ~18.6% of babies born are LBW (RSOC 2014) vs. ~4% in developed countries
• Prematurity is the #2 cause of death in children under 5, and #1 cause of death in the first month of life
• >90% of extremely preterm babies (< 28 weeks) in low-income countries die within the first few days; <10% die in high-income countries
• Infant mortality rate is ~20 times greater for LBW babies than normal-weight babies
• India has the highest absolute number of preterm births globally (3.5 million/year)

6. Causes of LBW (Risk Factors)

Maternal Factors:

• Malnutrition and anaemia (most significant in India)
• Heavy physical labour during pregnancy
• Infections (malaria, UTI, CMV, toxoplasmosis, rubella, syphilis)
• Hypertension / pre-eclampsia / eclampsia
• Diabetes
• Very young maternal age, high parity
• Short inter-pregnancy intervals
• Short maternal stature
• Smoking

Others:

• Multiple pregnancy
• Congenital abnormalities
• Placental insufficiency

7. Problems of LBW / Preterm Babies (System-wise)

A. Temperature

• Temperature instability - inability to stay warm due to low body fat and large surface area to body weight ratio

B. Respiratory

• Hyaline membrane disease (HMD) / RDS - lack of surfactant → air sacs cannot stay open
• Bronchopulmonary dysplasia (BPD) - chronic lung disease
• Apnoea - occurs in ~50% of babies born ≤ 30 weeks
• Air leak syndromes
• Incomplete lung development

C. Cardiovascular

• Patent ductus arteriosus (PDA) - blood diverts away from lungs
• Hypotension or hypertension
• Bradycardia (often with apnoea)

D. Blood and Metabolic

• Anaemia - may need transfusion
• Jaundice - liver immaturity
• Hypoglycaemia - low glycogen stores
• Hypocalcaemia
• Electrolyte imbalances

E. Gastrointestinal

• Feeding difficulty - unable to coordinate suck-swallow before 35 weeks
• Poor digestion
• Necrotizing enterocolitis (NEC)

F. Neurological

• Intraventricular haemorrhage (IVH) - bleeding into the brain
• Periventricular leukomalacia (PVL) - softening around ventricles
• Poor muscle tone
• Seizures
• Cerebral palsy - especially due to hypoxia/IVH

G. Infections

• Immature immune system → sepsis, meningitis, pneumonia

H. Ophthalmological

• Retinopathy of prematurity (ROP) / Retrolental fibroplasia - excess oxygen use

8. Leading Causes of Death in LBW Babies

1. Atelectasis
2. Malformations
3. Pulmonary haemorrhage
4. Intracranial bleeding (secondary to anoxia or birth trauma)
5. Pneumonia and other infections

9. Treatment / Care of LBW Baby

Based on Birth Weight Groups:

A. Thermal Care (Preventing Hypothermia)

• Incubator care: adjustment of temperature, humidity, oxygen supply
• KMC (Kangaroo Mother Care): for stable babies < 2000 g
• Maintain baby temperature: 36.5-37.5°C
• Room temperature: 25-28°C
• Wrap, cap, warm surfaces

B. Incubatory Care (3 Elements)

1. Temperature + humidity + oxygen adjustment
2. Continuous SpO2 monitoring: hypoxia → cerebral palsy; excess O2 → retrolental fibroplasia (ROP)
3. Infection prevention

C. Feeding

• Breastfeeding preferred and should be used if available
• Baby usually cannot suck in very preterm → feeding by nasal catheter / orogastric tube / cup
• Progress: parenteral nutrition → tube feeds (expressed breast milk) → cup/spoon feeds → direct breastfeeding
• Sucking coordinated only after 35 weeks gestation

D. Prevention of Infection

• Infection is the greatest hazard - death can occur within hours of respiratory infection
• Strict handwashing before handling baby
• Aseptic technique for all procedures
• Avoid unnecessary instrumentation
• Limit visitor exposure

E. Respiratory Support

• Supplemental oxygen (carefully monitored)
• CPAP for RDS
• Mechanical ventilation if needed
• Surfactant therapy for HMD/RDS

F. Monitoring

• Temperature, HR, SpO2, RR, BP continuously
• Blood glucose (hypoglycaemia common)
• Serum bilirubin (jaundice)
• Weight gain (target: 15-20 g/kg/day)

G. Kangaroo Mother Care (KMC)

• For stable babies < 2000 g
• Skin-to-skin contact + breastfeeding + early discharge + family support
• Reduces mortality, infection, hypothermia (covered in KMC notes)

10. Facility-Based Newborn Care (Indian Context)

11. Prevention of LBW

Direct Interventions (Antenatal):

1. Increased food intake - supplementary feeding, iron-folic acid supplementation, food fortification
2. Control infections - treat malaria, UTI, CMV, toxoplasmosis, rubella, syphilis
3. Early detection/treatment of hypertension, pre-eclampsia, diabetes

Indirect Interventions:

• Family planning
• Avoiding smoking
• Improved sanitation
• Improving health/nutrition of young girls
• Maternity leave with full wages
• Folic acid fortification
• Education and empowerment of women
• Improved socioeconomic conditions
