TITLE :Profile and outcome of very low birth weight (VLBW) infants at a public health tertiary care NICU in North India Yogesha K N , Sushma Nangia, Debasish Nanda, Department of Neonatology, Lady Hardinge Medical College, New Delhi Background
Background
- In recent WHO report, approximately 2.9
million neonates die annually in the world.
- Complications of prematurity is one the
leading cause for neonatal death
- About 15million premature births in the world
and a million of children die each year due to complications of preterm birth
WHO report 2014 Born Too Soon The Global Action Report on Preterm Birth 2012
Background
- WHO defines Very low birth weight babies (VLBW) as
birth weight < 1500 grams at birth irrespective of gestational age.
- The incidence of VLBW babies is less than 2% of the
births globally.
- In India, VLBW babies constitute 4% to 7% of the live
births and approximately 30% of neonatal death

Advances in neonatal care like, 1. Antenatal corticosteroids(ANS) 2. CPAP 3. Other modes of non invasive ventilation 4. Surfactant therapy 5. Gentle mechanical ventilation 6. Better understanding of disease process 7. Early enteral nutrition has resulted in improved survival of VLBW infants. Data related to survival and morbidity profile of VLBW infants is largely from high income countries. Similar data from LMICs is limited

Background
Objective
To evaluate the clinical profile of VLBW infants from a tertiary care NICU of a public health Institution from North India
Study design
Type of study : Prospective observational study Place of study : Nursery of Smt Sucheta Kriplani Hospital
and Neonatal ward of Kalawati Saran Children’s Hospital & Lady Hardinge Medical College–a tertiary care centre with facility for ventilation and care of sick neonates.
Duration of study : 24 months (Jan 2016 to Dec 2018) Study Subjects : All neonates with birth weight less than
1500gm.
Inclusion criteria
All neonates of gestational age(GA) less than 1500gms will be enrolled
Exclusion criteria
- Major congenital malformation
- Gestation less than 25 weeks
- Refusal for consent
End point of the study
The subject will be followed up to
- Discharge from the hospital
- Death
Results
- Out of 25782 live births during the study period,
944 (3.7%) infants were VLBW and were admitted to the NICU.
- Mean gestation age was 30+3 (24-39) weeks with
90% below 34 weeks and mean birth weight was 1157+327 (500-1498) gm.
- Overall(VLBW) survival was 84.2%, its in consistent with developed
country study by Eric C. Eichenwald et al (survival is 84%)
- Study from India showed, the neonatal mortality rate till discharge
was 15.7% in VLBW group and 33.3% in ELBW group.
- In S Murki et al study VLBW survival is 88%.
- About 70.5% survival in south african study

Results
- Partial/complete course of antenatal
corticosteroids was received by 68% mothers.
- About a third of the infants had one or more
antenatal risk factors for early onset sepsis.
- Around 23% (213) required surfactant
therapy with 76% receiving it by INSURE technique.

Survival(%)
Causes for mortality
Sepsis IVH (grade ≥ 3) NEC Extreme prematurity
Outcomes
Most common morbidity was sepsis (46.6%) followed by RDS (42%), it is consisted with many studies conducted in LMIC but RDS is most common morbidity in developed countries .

- Klebsiella spp. being the commonest isolate
(35%) followed by Staphylococcus aureus (20%), it is consisted with Indian data
- Meningitis was diagnosed in 6% cases.

Outcomes
- Ten percent developed any grade of IVH with
2% having severe IVH (IVH grade ≥ 3),
- More than 2% (2.2%) developed NEC stage 2
- r higher
- Any stage ROP was identified in nearly 5.2%
and 2.6% required treatment
Outcomes
- Additionally, 5.2% had HsPDA requiring
pharmacologic closure, 1.3% developed airleak
- Three percent of the cases required
- xygen(O2) therapy beyond 28 days of life and
- nly 1/4th of these continued to require O2
