Insights
Black cotton fabric, with or without foam, effectively shields newborns from harmful light during intensive phototherapy for jaundice. This finding is crucial for preventing retinal damage in infants undergoing this common treatment.
Area of Science:
- Neonatal care
- Ophthalmology
- Biomedical engineering
Background:
- Neonatal jaundice is a common condition requiring phototherapy, which converts toxic bilirubin to a harmless form using light.
- Intensive phototherapy, while effective, poses a risk of retinal damage to newborns.
- Current eye protection methods vary, with limited data on their efficacy during intensive phototherapy.
Purpose of the Study:
- To assess the effectiveness of various eye protectors used in neonatal intensive phototherapy.
- To identify the best shielding materials for preventing light-induced eye injury in jaundiced newborns.
Main Methods:
- Five common eye shielding materials were tested.
- Irradiance levels were measured using an Olympic bili meter during intensive phototherapy from a custom LED device.
- Shielding effectiveness was determined by measuring irradiance reduction when materials were placed over the sensor at various distances.
Main Results:
- Black cotton fabric, with or without foam padding, demonstrated complete shielding, recording zero irradiance.
- Other materials like white cotton fabric, foam-padded white cotton, and gauze showed varying degrees of light transmission.
Conclusions:
- Black cotton fabric, with or without foam, is the most effective eye protection material during intensive neonatal phototherapy.
- These findings can guide the selection of optimal eye shields to enhance infant safety during jaundice treatment.
Background:
Phototherapy remains an important component of the management of unconjugated neonatal jaundice, a major cause of newborn morbidity. During phototherapy the toxic unconjugated form of bilirubin is converted to nontoxic form through action of light delivered by phototherapy. An important possible complication of phototherapy is retinal damage and therefore eye protective measures are taken during therapy to prevent this from occurring. Devices currently in use for phototherapy are capable of providing intensive phototherapy with the attendant increased risk of eye injury. The materials used in providing eye protection are varied among care providers. A dearth of information exists on shielding provided by the commonly used eye protectors during phototherapy, more so during intensive phototherapy.
Objective:
To evaluate the shielding provided by the different eye protectors commonly used in our setting under intensive phototherapy.
Materials And Method:
Five materials in use for eye shielding were obtained. Using an institutional built light emitting diode phototherapy device, intensive phototherapy was provided and the irradiance at varying distances of 35 cm, 25 cm, 15 cm and 10 cm was measured using an Olympic bili meterTM Natus. At the distance of each measured irradiance the different eye protective materials were then placed one after the other over the surface of the measuring sensor of the meter and the irradiance measurement was recorded. Two measurements were taken for each material at each distance and the average irradiance measurement was then recorded for each of the materials tested at that distance.
Results:
Five eye shielding materials in use were identified: black cotton fabric, white cotton fabric, black cotton fabric with foam, white cotton fabric with foam and gauze. The black cotton fabric with or without foam at the phototherapy device irradiances of 30, 46.3, 58.7 and 75.4 µw/m2/nm recorded 0 irradiance.
Conclusion:
Black cotton fabric with or without foam pad provided the most shielding under intensive phototherapy.
