Subgaleal hemorrhage: risk factors and outcomes.

Subgaleal hemorrhage in the newborn is a serious adverse event that is often unrecognized and under-appreciated. This retrospective case series aimed to determine perinatal factors associated with subgaleal hemorrhage and subsequent neonatal outcomes. Obstetric and neonatal details of 21 infants with subgaleal hemorrhage over a 10-year period were collected. The mother was primiparous in 95% cases, 48% had a prolonged second stage (>120 minutes) and 43% had prolonged rupture of membranes (>12 hours). Thirteen infants (62%) were born by instrumental vaginal delivery. Ten infants (48%) required resuscitation at delivery. The severity of subgaleal hemorrhage was mild in four infants (19%), moderate in 10 (48%) and severe in seven (33%). Hypovolemic shock developed in 10 infants (48%), encephalopathy in 13 (62%) and coagulopathy was present in five infants (24%). There were three (14%) deaths. Long-term outcomes were good in the surviving infants.
