Insights
Early Kangaroo care (KC), involving skin-to-skin contact, significantly reduces mortality risk in very preterm and very low birth weight infants. While infection risk was not significantly reduced, KC shows promise for improving neonatal outcomes.
Area of Science:
- Neonatal Medicine
- Pediatrics
- Evidence-Based Healthcare
Background:
- Kangaroo care (KC) is recognized for its benefits in preterm and low birth weight infants.
- Early initiation of KC, including skin-to-skin contact and early breastfeeding, is crucial.
Purpose of the Study:
- To evaluate the effectiveness of early Kangaroo care (KC) initiated within 24 hours.
- To compare early KC versus conventional neonatal care for very preterm (≤32 weeks) and/or very low birth weight (<1,500g) infants.
Main Methods:
- Systematic review and meta-analysis of four randomized controlled trials (RCTs).
- Included 1,679 newborns comparing early KC to conventional care.
- Risk of bias assessed using the Cochrane Risk of Bias tool; meta-analysis performed using R.
Main Results:
- Early KC significantly reduced mortality risk (RR=0.81, 95% CI: 0.67-0.98).
- Pooled risk ratio for infection was 0.89 (95% CI: 0.77-1.02), not statistically significant.
- Observed mixed effects on hypothermia with moderate heterogeneity.
Conclusions:
- Early KC demonstrates potential to decrease mortality and morbidity in very preterm and VLBW infants.
- Further research is needed for infants <1,000g or born before 28 weeks gestation.
- Effects on hypothermia warrant further investigation.
Objectives:
Kangaroo care (KC), involving skin-to-skin contact, early breastfeeding and early discharge, demonstrated benefits in improving outcomes for preterm and low birth weight infants. This systematic review and meta-analysis aimed to evaluate the effectiveness of early KC (initiated within the first 24 h) vs. conventional neonatal care in very preterm infants (≤32 weeks) and/or very low birth weight (VLBW) infants (<1,500 g).
Methods:
A comprehensive search of MEDLINE, SCOPUS, Web of Science, and CENTRAL databases was conducted. Randomized controlled trials (RCTs) comparing early KC to conventional care in very preterm and/or VLBW infants were included. Risk of bias was assessed using the Cochrane Risk of Bias tool. Meta-analysis was conducted using R, with relative risks (RR) and 95 % confidence intervals (CI) calculated.
Results:
Four RCTs, encompassing 1,679 newborns, were included. Meta-analysis revealed a significant reduction in mortality risk (RR=0.81, 95 % CI: 0.67-0.98) with early KC. The pooled RR for infection risk was 0.89 (95 % CI: 0.77-1.02). The impact on hypothermia was mixed, with moderate heterogeneity observed.
Conclusions:
Early KC may reduce mortality and morbidity in very preterm and VLBW infants although its effects on hypothermia vary by severity. Further studies are required to assess its effects on infants weighing <1,000 g or born before 28 weeks of gestation.
