RESUMO
We present twins born to the 31-year-old, multigravida mother, who were referred to our centre at 90 hours of life for severe hyperbilirubinaemia. Twin 1 had already received two double volume exchange transfusions at 55 and 83 hours of life, in view of the persistent rise in bilirubin despite receiving phototherapy. Twin 2 had received phototherapy and 1 packed red blood cell transfusion in view of the fall in haematocrit. Mother's blood group was B positive and that of both twins was O positive. Both the twins were started on intensive phototherapy and their serum bilirubin and haematocrit were evaluated. On investigation, a minor blood incompatibility was found. Double volume exchange transfusion was done for twin 2 at 100 hours of life in view of the rapid rise in serum bilirubin. Both the babies were monitored for their serum bilirubin and treated for sepsis and discharged after 15 days.
