Treatment





                         Description of included studies
                         Babies in both studies were allocated to treatment according to their hospital numbers, and thus
                         allocation concealment was not possible.

                         Agar was given in 250 mg oral doses either every 8 hours during phototherapy or at each 3-
                         hourly  feed.  The  samples  in  both  studies  were  comparable,  with  mean  birthweight  of
                         2767 ± 69 g  and 2729 ± 538 g, mean age at entry to study of 80.6 ± 28.7 hours and
                         87 ± 26 hours,  and   mean    serum   bilirubin  of   234 ± 46.8 micromol/litre   and
                         274 ± 51 micromol/litre. One study 223  reported the mean gestational age of 36.8 ± 2.5 weeks.
                         Of the combined sample, 57 participants (56.4%) were male.

                         Review findings
                         When both  studies  were  pooled in a meta-analysis,  there  was no  statistically  significant
                         difference  between  treatment  and  control  groups  in  mean  reduction  in  serum  bilirubin
                         (MD = −2.00 micromol/litre, 95% CI −24.13 to 20.13 micromol/litre). Also there there was no
                         statistically  significant difference in  the  mean duration of phototherapy (MD = −6.57 hours,
                         95% CI −16.06 to 2.92 hours). Heterogeneity was low at I² = 21%.

                         Barbiturates
                         Eighteen  articles were obtained, including one  controlled clinical trial  from New Zealand 224
                         concerning phenobarbitone treatment of hyperbilirubinaemia. Seventeen papers were excluded
                         for the following reasons:  phototherapy not  evaluated concurrently (two studies),
                         phenobarbitone evaluated for prophylaxis, not treatment, of jaundice (12), maternal treatment
                         with phenobarbitone evaluated (two) and no jaundice-related outcomes included (one).

                         Description of included studies
                         In one controlled clinical trial  [EL 2−]  the mean gestational age of the  sample was
                         34.8 ± 2.7 weeks, the mean birthweight was 2155 ± 632 g, the mean age at entry to study was
                         48.1 ± 14.7 hours, and the mean serum bilirubin was 174 ± 40 micromol/litre. Forty-nine (49%)
                         of the sample were male. Babies who met the criteria for phototherapy were allocated to routine
                         care, routine care  and  phototherapy,  or  routine care,  phototherapy and phenobarbitone.
                         Allocation to treatment was on a rotational basis and allocation concealment was not reported.
                         Babies with birthweight  > 3000 g  received 8 mg of phenobarbitone three times  daily while
                         those babies with birthweight < 3000 g received 2 mg/kg of phenobarbitone three time daily.
                         Review findings
                         No baby  who received phototherapy alone required  an exchange transfusion but one who
                         received phenobarbitone combined with phototherapy had an exchange transfusion. This was
                         attributed to extensive bruising aggravating hyperbilirubinaemia.  Babies  who received
                         phenobarbitone received phototherapy for longer than control babies (72 ± 31 hours versus
                         67 ± 33 hours).

                         D-penicillamine
                         Three articles were obtained and all were excluded. Two were historical control studies and one
                         was a controlled clinical trial examining D-penicillamine as prophylaxis for hyperbilirubinaemia
                         in preterm babies.
