Supportive Care for Common Conditions in Small Vulnerable Newborns and Term Infants: The Evidence.

Introduction: Small vulnerable newborns (SVNs) are at an increased risk of early death and other morbidities. Essential interventions provided to SVN, and other high-risk newborns have been proven critical in improving their outcomes. We aimed to provide an update on the effectiveness and safety of these interventions in low- and middle-income countries (LMICs).

Method: Following a comprehensive literature scope, we updated or reanalyzed LMIC-specific evidence for essential SVN care interventions.

Results: A total of 113 individual LMIC studies were identified. Most of them were of high risk of bias. Kangaroo mother care significantly reduced SVN's mortality by discharge. Early erythropoiesis stimulating agent lowered SVN's risk of receiving blood transfusion. Prophylactic oral or intravenous ibuprofen resulted in a decreased risk of patent ductus arteriosus in SVN. But it did not have a significant effect on mortality and led to a higher risk of gastrointestinal bleeding. No pooled LMIC data were available for universal screening of hyperbilirubinemia in high-risk newborns. Sunlight therapy had no effect in treating hyperbilirubinemia but increased the risk of hyperthermia. Reflective curtains with phototherapy resulted in a greater and faster decline in bilirubin than standard phototherapy in treating hyperbilirubinemia. Early child development interventions were shown to have a favorable effect on cognitive and motor scores in SVN. The evidence for family involvement and family support was limited and uncertain.

Conclusion: We present the most updated LMIC evidence for interventions targeting SVN. Despite their effectiveness and safety in improving certain neonatal outcomes, further high-quality trials are required.
