Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intensified phototherapy with single fluorescent unit (one Bilicompact light) vs Double fluorescent unit (double bilicompact. light) vs phototherapy with Photodiodes (Neoblue).
The neoBLUE unit emits blue LED light in the 450-470 nm with peak at 468 nm spectrum. This range corresponds to the bilirubin peak absorption wavelength of 458 nm.
BiliCompact contains ten 9W,12.7-cm length fluorescent bulbs (BAM/PL9/52, Ralutec 9W/71 G 23). These bulbs have broad Gaussian emission spectra roughly from 400 -525 nm with a peak at 450 nm and intense mercury emission lines at 405, 436, and 546 nm
Arm 1: Single phototherapy provided by one unit neoBLUE `Trademark`
Arm 2: Single phototherapy with single unit BiliCompact.`Trademark`. Arm 3: Double phototherapy was administered by two units BiliCompact`Trademark`.
We will take blood sample to analyse bilirubin photoisomer right befor starting phototherapy, after 30 min.60 min, 120 min Duration of phototherapy depends on the patient's response to phototherapy and how quickly falls serum total bilirbin. For this study, all children receive phototherapy at least 2-4 hours, because we are interested to see how quickly formed fotoisomerer after 15 min, 30min, 60 min, 120 min and 240 min.and 240 min. during phototherapy.

Comparator / control treatment
In our study we compare the effect of these types of phototherapy. We ciompared singel flourescent vs. single LED photodiodes vs double flourescent phototherapy.
By conventional phototherapy means the standard phototherapy which uses usually in the department, here is flourescent phototherapy. We would use intensive phototherapy to babies which needs phototherapy according to national Norwegean guidelines.
Phototherapy will provide by flourescent units
(1 or 2 lamps Bilicompact) and with single photodiodes (neoBLUE) unit at distance of 20 cm.The bed of patient will be covered inside with white linen and by hanging white linen around the unit .

Outcomes
Primary outcome [1] 238022 0
Formation of bilirubin isomers.
Stereoisomers of bilirubin formed during phototherapy.
We will measure these photoisomers by HPLC method. HPLC ( High-performance Liquid Chromaatography) for analyse of photoisomer.W will measure photoisomers who formed at 0 min, 15 min, 30 min., 60 min, 120 min & 240 min.
HPLC method: Bilirubin isomer were analyzed on a Dionex ultimate 3000 system , including a multiple wavelength detector ( Dionex, Sunnyvale, CA). The collumn used for HPLC was Kinetex core-shell 2,6 um C-18 ( 15 x0,46 cm).
Timepoint [1] 238022 0

Measuring the time of phototherapy.
Timepoint [1] 242157 0

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Accepted by the local ethics committee. Informed consent from the parents. Closed envelopes with infomation of which treatment to provide.(random sorted)
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Enrolled infants were randomized by drawing of sealed envelopes, to be treated with:
1) single fluorescent phototherapy (BiliCompact Infant or
2) double fluorescent phototherapy (BiliCompact), or
3) single unit photodiodes

Summary
Brief summary
Bilirubin photoisomers theoretically should be less able to cross the blood-brain barrier.Therfore it is of interest to study early bilirubin izomerization during phototherapy.
