Context

Phototherapy (PT) is the standard treatment for neonatal hyperbilirubinaemia. It prevents the need for exchange transfusion (ET) by lowering total serum bilirubin (TSB). In many resource constrained regions of the world, PT devices are unavailable, or unusable due to irregular power supply or ineffective because of inadequate quantity and quality of PT lamps. This contributes to an avoidable burden of 150 000 deaths and disabilities.1

Sunlight provides high irradiance and bleaches the jaundiced serum in vitro. However, sunlight is not recommended because of risks of UV and infrared wavelengths and temperature instability. The investigators developed canopies from low cost light-filtering films to block almost all UV-A, UV-B and UV-C light and some …
