Comments:

There was a blood incompatibility in 11 of the 16 babies. For 3 cases, the bilirubin level exceeded the critical threshold (of 340 µMOL) requiring a blood transfusion exchange. 
Results of the tests are very clear. A rapid decline of the bilirubin level was observed in 13 cases. The remaining 3 cases concerned dark-skinned babies in which the decline logically progresses slower due to the pigmentation of their skin


Advantages of the BiliCrystal System in comparison with the standard phototherapy


Conventional phototherapy devices develop an energetic illumination between 0.5 and 3,0  mW/cm². An efficient treatment needs to achieve at least 1,6 mW/cm². The energetic illumination of intensive phototherapy needs to be superior to 3,0 mW/cm².

It is imperative for conventional phototherapy lights to treat the baby on a longer period(36 to 48 hours consecutive) than intensive phototherapy. This long exposure time can entail irreversible damages such as severe neurological problems because of the emitted ultraviolet and infrared. Even more, because of heat, the baby has to be placed far enough from the source of light. He has to be placed on its back and front to flood the whole body with light. The newer machines permit a total exposure under the light source because the baby is placed on a transparent hammock with a reflector on top so the whole body of  the baby is irradiated.

Intensive phototherapy allows a much higher energetic level of irradiation than the conventional phototherapy

The part of the light spectrum used by the BC system has demonstrated a higher efficiency than the standard photo therapy



 The Bilicrystal phototherapyThe standard phototherapy
The light spectrum Larger light spectrum : the blue and the green's parts, which dissociate the whole bilirubin Blue light, which dissociate a part of the bilirubin
Phototherapy Treatment period 4 to 6 hours 36 to 48 hours (light therapy with UV which increases the risk of nevi)
Duration of baby's stay in hospital Shortened Prolonged by the treatment
Mother-baby's proximity Only 4 hour during treatment Whole treatment period
Incubator The system can be use even in a closed incubator Not in incubator
Security Baby and System temperature are monitored No monitoring
Blood transfusion Can be avoided in 90% of the cases Needed
Luminous intensity 2.000 hours/lamp 800-1.000 hours/lamp
