                         DVET versus no treatment
                         The first RCT 193  carried out in the USA compared exchange transfusion with no treatment in 100
                         babies with indirect serum bilirubin > 307.8 micromol/litre. Babies were less than 1 week old.
                         Demographic details and method  of randomisation were not reported  although sealed
                         envelopes were used to conceal allocation to intervention groups. There were three deaths in
                         each  group, none attributable to exchange transfusion. One baby in  the  control group had
                         kernicterus confirmed by autopsy. Seven of the exchange transfusion group had an abnormal
                         neurological examination at 12–24 months compared with six in the control group. [EL 1+]
                         DVET versus simple transfusion
                         This RCT 194;195   compared exchange transfusion with simple top-up transfusion in  137 babies
                         with  haemolytic  disease  of  the  newborn.  All  transfusions  were  carried  out  within  9 hours  of
                         birth. Sample demographics and method of randomisation were not reported although sealed
                         envelopes were used to conceal allocation to intervention groups. There were  statistically
                         significantly fewer deaths in the exchange transfusion group (RR 0.26, 95% CI 0.11 to 0.60) and
                         also statistically significantly fewer cases of kernicterus (RR 0.38, 95% CI 0.17 to 0.87). [EL 1+]
                         DVET versus single-volume exchange transfusion
                         This RCT, 196   carried out in Switzerland, compared DVET with  single-volume exchange
                         transfusion (SVET)  in  the  management  of ABO  haemolytic  disease. Twenty babies  were
                         included, of whom 15 (75%)  were male. The mean gestational age of the sample  was
                         39.5 ± 1.0 weeks, the mean birthweight was 3305 ± 392 g, the mean age at entry to study was
                         17.9 ± 6.1 hours,  and  the  mean  serum  bilirubin  was  207 ± 45 micromol/litre.  A  random
                         numbers table was used to allocate babies to the groups but allocation concealment was not
                         reported.  Both  interventions  were  initiated  according  to  the  modified  Polacek  curve  as
                         described by Cockington. 200  There was no statistically significant difference between SVET and
                         DVET in mean reduction of serum bilirubin, mean duration of adjunctive phototherapy and
                         level of rebound hyperbilirubinaemia. There were no cases of kernicterus or reported adverse
                         effects in either group. [EL 1−]
                         Exchange transfusion versus phototherapy
                         An RCT, 197  carried out in Singapore, compared DVET with phototherapy for the management of
                         non-haemolytic hyperbilirubinaemia. In all, 52 babies were included, of whom 28 (54%) were
                         male. The mean gestational age of the sample was 37.0 ± 2.78 weeks, the mean birthweight
                         was 2501 ± 576 g,  the  mean  age  at entry to study was  84 ± 12 hours,  and  the  mean serum
                         bilirubin was 297 ± 25 micromol/litre. Both interventions were  initiated at serum  bilirubin
                         > 256.5 micromol/litre in preterm babies and > 307.8 micromol/litre in term babies. Neither
                         the method of  randomisation  nor  allocation concealment  was reported but there  were no
                         significant differences between the groups on any baseline variable. There was a statistically
                         significantly greater reduction in mean serum bilirubin 24 hours after initiation of treatment in
                         the phototherapy group (MD = 51 micromol/litre, 95% CI 39.7 to 62.3 micromol/litre). In the
                         exchange transfusion group there was an initial fall in serum bilirubin levels at 6 hours but this
                         was rapidly followed by rebound hyperbilirubinaemia. There were more treatment failures in
                         the exchange transfusion group, with eight babies requiring repeat exchange transfusion, while
                         no babies in the phototherapy group required additional treatment. The RR of treatment failure
                         in  the  exchange  transfusion  group  was  statistically  significant,  although  confidence  intervals
                         were  wide,  at  17.00  (95% CI  1.03  to  280.07).  There  were  no  cases  of  kernicterus  in  either
                         group. [EL 1−]

                         Alternative methods for DVET
                         The fifth RCT, 198  carried out in Canada, compared conventional DVET with albumin-enriched
                         DVET. A total of 42 babies were included, of whom 25 (60%) were male, and 27 (64%) had
                         Rhesus or ABO incompatibility. The mean gestational age of the sample was 36.0 ± 0.7 weeks,
                         the  mean  birthweight  was  2455 ± 153 g,  and  the  mean  serum  bilirubin  was
                         263 ± 82 micromol/litre. Neither the method of randomisation nor allocation concealment was
                         reported but there were no significant differences between the groups on any baseline variable.
                         There was no statistically significant difference between DVET and albumin-enriched DVET in
                         mean reduction of serum bilirubin, mean duration of adjunctive phototherapy and the degree of
