Abstract:
Objective To evaluate the efficacy of blue-green light phototherapy for jaundice in preterm newborns.Methods Total 124 preterm newborns with birth-weight below 2000 g were included in this study.Infants in group A (gestation age ≤32 weeks or/and instability,n =72) were treated with bluegreen light (group A1 ) or with single side blue light (group A2) randomly.Infants with gestation age ＞32weeks or/and stability (n =52) were also treated with blue-green light (group B1 ) or with single side blue light ( group B2) randomly.Peak levels of serum bilirubin ( PSB),the withdrawal time of jaundice and the duration of phototherapy were compared between groups.Results Group A:PSB of groupAl was lower than that of groupA2 [ (219 ± 31 ) μmol/L vs.( 257 ± 39 ) μ mol/L,P ＜ 0.01 ].The withdrawal time of jaundice group Al was earlier than that of group A2 [ ( 10.3 ±3.0) d vs.( 16.2 ±4.2) d,P ＜0.01 ].The duration of phototherapy of groupA1 was shorter than that of group A2 [ (87 ±34) h vs.(23 ±49) h,P ＜0.01 ].Group B:There were no differences in PSB and withdrawal time of jaundice between two subgroups ( P ＞0.05).The duration of phototherapy of groupB1 was shorter than that of group B2 [ (59 ±23) h vs.(73 ±74) h,P ＜ 0.05 ].Conclusion Blue-green light phototherapy is more effective than single side of blue light in treatment of jaundice in preterm newborns.
