Insights
A small percentage of newborns (7.3%) experience significant bilirubin rebound after phototherapy. Key risk factors for this rebound include prematurity and late jaundice onset, guiding post-discharge care.
Area of Science:
- Neonatal Medicine
- Pediatrics
- Clinical Research
Background:
- Hyperbilirubinemia is common in newborns.
- Phototherapy is a standard treatment.
- Post-phototherapy bilirubin rebound requires monitoring.
Purpose of the Study:
- To determine the incidence and magnitude of post-phototherapy bilirubin rebound.
- To identify risk factors for significant bilirubin rebound (SBR).
Main Methods:
- Prospective study of inborn neonates requiring phototherapy.
- Bilirubin levels measured 24+/-6 hours after phototherapy cessation.
- Significant bilirubin rebound (SBR) defined as bilirubin requiring phototherapy re-initiation.
Main Results:
- 17 out of 232 neonates (7.3%) developed SBR.
- Bilirubin increased by 2.3 mg/dL in neonates with SBR.
- Risk factors for SBR included gestational age >35 weeks, birthweight <2000 g, and jaundice onset >60 hours.
Conclusions:
- Significant bilirubin rebound occurs in a notable proportion of neonates.
- Prematurity, low birthweight, and delayed jaundice onset are associated with SBR.
- Discharge and follow-up planning should consider these identified risk factors.
Abstract:
This study was conducted to determine the incidence and magnitude of post-phototherapy bilirubin rebound in neonates. Subjects included inborn neonates needing phototherapy for hyperbilirubinemia. Standard guidelines were used to start and stop phototherapy. Rebound bilirubin was measured 24+/-6 h after stopping phototherapy. Significant bilirubin rebound (SBR) was defined as post-phototherapy bilirubin level needing reinstitution of phototherapy. Among 245 neonates with hyperbilirubinemia, post-phototherapy bilirubin estimation was done in 232 neonates. A total of 17 (7.3%) neonates developed SBR. In neonates with SBR, bilirubin increased by 2.3 mg/dL (95% CI 1.6-3.0) after stopping phototherapy. Risk factors for SBR included birth at >35 weeks of gestation (RR 4.3, 95% CI 1.5-12.0), birthweight <2000 g (RR 3.2, 95% CI 1.0-10.3) and onset of jaundice at >60 h of age (RR 3.3, 95% CI 1.2-9.0). Post-phototherapy discharge and follow-up planning should take into account these risk factors.
