Introduction All babies develop elevated serum bilirubin (SBR) levels, to a greater or lesser degree, in the first week of life. This is due to: increased production(accelerated RBC breakdown); decreased removal (liver enzyme insufficiency) Increased reabsorption(enterohepatic circulation)

Etiology and Epidemiology of ICH >Trauma (epidural, subdural, or subarachnoid) fetal head is too large in proportion to the size of the pelvic outlet prolonged labor/breech or precipitate deliveries
