Insights
Continuous transcutaneous oxygen monitoring (tcPO2) may reduce retinopathy of prematurity (ROP) in preterm infants over 1000 grams. However, it did not significantly impact ROP incidence in smaller infants.
Area of Science:
- Neonatalogy
- Pediatric Ophthalmology
- Critical Care Medicine
Background:
- Retinopathy of prematurity (ROP) is a significant cause of visual impairment in preterm infants.
- Oxygen therapy is crucial for preterm infants but carries risks for ROP development.
- Current monitoring practices for oxygenation vary, impacting ROP outcomes.
Purpose of the Study:
- To investigate if continuous transcutaneous oxygen monitoring (tcPO2) reduces ROP incidence in preterm infants receiving oxygen therapy.
- To compare ROP rates between continuous monitoring and standard care groups.
Main Methods:
- A randomized controlled trial involving 296 preterm infants (birth weight ≤ 1300 grams).
- Infants were assigned to either continuous tcPO2 monitoring (CM) or standard care (SC) groups.
- tcPO2 was monitored continuously in the CM group and intermittently in the SC group during acute illness.
Main Results:
- Overall ROP incidence was 51% in the CM group and 59% in the SC group.
- Continuous tcPO2 monitoring showed a potential reduction in ROP for infants >1000g birth weight.
- No significant difference in ROP incidence was observed for infants <1000g birth weight.
Conclusions:
- Continuous tcPO2 monitoring may be beneficial in reducing ROP in larger preterm infants (>1000g).
- Smaller preterm infants (<1000g) with higher ROP risk and severity may not benefit from this monitoring strategy.
- Further research is needed to optimize oxygen management for high-risk preterm infants.
Abstract:
This study was performed to determine whether the use of continuous tcPO2 monitoring could reduce the incidence of ROP in preterm infants receiving oxygen therapy. Two hundred and ninety-six infants with birth weights less than or equal to 1300 grams were randomly assigned to a continuous monitoring (CM) or a standard care (SC) group. CM infants had tcPO2 monitored continuously as long as they required supplemental oxygen while SC infants had tcPO2 monitored only during the more acute state of their illness. Management of both groups was otherwise identical. One hundred and one of 148 infants in the CM and 113 of 148 patients in the SC groups survived. Mean birth weights and gestational age were similar in both groups. Duration of mechanical ventilation and oxygen therapy was also similar. The overall incidence of ROP was 51% in the CM and 59% in the SC group. As birth weight for infants greater than or equal to 1000 grams increased a higher risk for developing ROP was noted in the SC group. Four infants in the CM and 5 in the SC group developed cicatricial ROP. These results suggest that continuous tcPO2 monitoring may reduce the incidence of ROP in infants with birth weights greater than 1000 grams, but not in the smaller infants in whom this complication occurs more frequently and is more severe.
