at maximal power. Irradiance was an

average of 19.01 microW/cm /nm when
measured at the centre and at the four
corners.

The standard fiberoptic phototherapy
consisted of a pad, 11 X 24 cm
(illuminated part was 11 X 16cm) which
was used without its sheath and at
maximal power. The irradiance was
calculated to be 23% more than that of
the standard fiberoptic pad.

The double fiberoptic phototherapy
consisted of two standard pads one on
the back and one the front of the baby.

Phototherapy was terminated when TSB
< 188 micromol/litre on at least two
occasions

Phototherapy was deemed to have failed
when TSB values exceeded start level
on at least two occasions and when
direct bilirubin was minimal < 0.6
