Introduction
When exposing newborns to blue light therapy, it is important to cover critical areas such as the eyes and genital region to prevent damage to the retinas or mucous membranes of the genital and anal areas. The duration of blue light exposure should also be carefully controlled: too short an exposure may result in inadequate reduction of jaundice, while excessive exposure can lead to erythema or petechiae on the skin surface. Additionally, bilirubin levels should be monitored daily to assess changes in jaundice.
General precautions for blue light therapy in newborns include covering vital areas, controlling the duration of blue light exposure, and monitoring bilirubin levels.
1. Covering vital areas
When newborns have high bilirubin levels due to jaundice that cannot be resolved with medication, blue light therapy can convert bilirubin into water-soluble isomers that are excreted through the intestines, thereby reducing jaundice. During phototherapy, it is important to cover the eyes, genital area, and other sensitive regions to prevent damage to the retina or mucous membranes and skin in areas such as the genitals and anus.
2. Controlling blue light exposure time
The duration of blue light exposure should be carefully managed. If the exposure time is too short, the treatment may not effectively reduce jaundice. Additionally, because a newborn's skin is delicate, prolonged exposure to blue light can irritate the skin, potentially causing rashes, redness, or petechiae (small red or purple spots caused by bleeding under the skin).
3. Monitoring bilirubin levels
Blue light therapy generally leads to a gradual decrease in visible signs of jaundice. During treatment, bilirubin levels should be monitored daily to track changes in jaundice and to promptly identify any abnormal conditions.
