Longitudinal Growth and Post-discharge Mortality and Morbidity Among Extremely Low Birth Weight Neonates.

Objectives: To study post-discharge growth, mortality and morbidity of extremely low birth weight neonates at corrected age of 2 years. Methods: Weight, length and head circumference were compared on WHO growth charts at corrected ages 3 (n=54), 6, 9, 12 (n=51) and 24 months (n=37); rates of underweight, stunting, microcephaly and wasting were calculated. Results: The mean Z-score for weight, length, head circumference and weightfor- length significantly improved from 3 to 24 months (P<0.001); a significant proportion remained malnourished at 2 years. Nine infants (11%) died and 35 (44%) required readmission during first year of age. Conclusion: Extremely low birth weight neonates remain significantly growth retarded at corrected age of 2 years.

Predictors of Mortality in Neonates with Meconium Aspiration Syndrome.

Objective: To identify risk factors for mortality in neonates with meconium aspiration syndrome. Methods: All neonates (2004-2010) with meconium aspiration syndrome, irrespective of gestation were included. Risk factors were compared between those who died and survived. Results: Out of 172 included neonates, 44 (26%) died. Mean (SD) gestation and birth weight were 37.9 (2.3) weeks and 2545 (646g), respectively. Myocardial dysfunction [aOR 28.4; 95% CI (8.0-101); P<0.001] and higher initial oxygen requirement [aOR 1.04; 95% CI (1.02-1.07); P<0.001] increased odds of dying while a higher birth weight [aOR 0.998; 95% CI (0.997-1.00); P=0.005] reduced the odds of dying. Conclusions: Meconium aspiration syndrome is associated with significant mortality. Myocardial dysfunction, birth weight, and initial oxygen requirement are independent predictors of mortality.

Predictors of Mortality and Major Morbidities in Extremely Low Birth Weight Neonates.

Objectives: To determine predictors of mortality and morbidity in extremely low birth weight neonates (ELBW) from a developing country Study design: Prospective observational study. Setting: Level III neonatal unit in Northern India. Subjects: Neonates <1000g born and admitted to intensive care during study period were enrolled. They were analyzed based on survival and development of major morbidity. Multivariable logistic regression model was used to determine independent risk factors. Outcome: Mortality and major morbidity (one or more of the following: Bronchopulmonary dysplasia (BPD), Retinopathy of Prematurity (ROP) requiring laser, grade III or IV intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL) and necrotizing enterocolitis (NEC) stage III) during hospital stay. Results: Of 255 ELBW neonates born, 149 received optimal care, of which 78 (52%) survived and 57 (39%) developed morbidities. Mean birth weight and gestational age were 29.1±2.6 weeks and 843±108g. Major causes of mortality were sepsis (46%), birth asphyxia (20%) and pulmonary hemorrhage (19%). Birth weight ≤800g [OR (95% CI)-3.51 (1.39-8.89), P=0.008], mechanical ventilation [4.10 (1.64-10.28), P=0.003] and hypotensive shock [10.75 (4.00-28.89), P<0.001] predicted mortality while birth weight ≤800g [3.75 (1.47-9.50), P=0.006], lack of antenatal steroids [2.62 (1.00-6.69), P=0.048), asphyxia [4.11 (1.45-11.69), P=0.008], ventilation [4.38 (1.29-14.79), P=0.017] and duration of oxygen therapy [0.004 (1.001-1.006), P=0.002] were the predictors of major morbidities. Conclusions: Low birth weight, mechanical ventilation and hypotensive shock predicted mortality in ELBW neonates while low birth weight, lack of antenatal steroids, birth asphyxia, ventilation and duration of oxygen therapy were predictors for major morbidity.

Survival and Morbidity Among Two Cohorts of Extremely Low Birth Weight Neonates from a Tertiary Hospital in Northern India.

This study was conducted to compare the survival and morbidity of extremely low birth weight neonates born during two different time periods (2009-10 and 2001-02) at a Level III referral neonatal unit in Northern India. All consecutive intramural extremely low birth weight neonates (<1000g), irrespective of gestation, and admitted to Intensive Care were enrolled. 149 and 123 neonates were enrolled during 2009-10 and 2001-02, respectively. The baseline characteristics were comparable except for mean birth weight, which was lower during 2009-10 (843±108g vs 885±126g, P=0.003). Surfactant therapy (54% vs 18%, P<0.001), non-invasive ventilation (28% vs 6%, P<0.001), high frequency ventilation (24% vs 4%, P=0.001), IVH (52% vs 25%, P<0.001) and PDA (34% vs 18%, P=0.004) were significantly more during 2009-10. Culture positive sepsis (33% vs 51%, P=0.003) and ROP rates (7% vs 23%, P=0.042) were significantly higher during 2001-02. Overall survival was similar; however, neonates between 28-30 weeks gestation had better survival (63%) during 2009-10 compared to 2001-02 (38%), P=0.009. Survival in neonates 28-30 weeks improved during this period while overall survival remained the same.
