Perioperative management of children with haemophilia undergoing surgery is a complex and understudied topic. Circumcision is the most common procedure performed in the neonatal period, and guidelines to prevent bleeding complications from circumcision are lacking. Treatment protocols vary widely, and many centres treat patients with factor products for up to two weeks after circumcision. There is an unmet need for studies evaluating optimal factor replacement therapy around the time of circumcision in neonates with severe haemophilia. Aim To determine the efficacy of a single dose of factor replacement before circumcision to prevent bleeding complications in neonates with severe haemophilia. Methods We conducted a retrospective chart review of male infants born between January 2000 and June 2019. Male neonates with severe haemophilia diagnosed at the Iowa Hemophilia and Thrombosis Center (n = 22) and healthy newborn controls who underwent circumcision at the University of Iowa Hospitals were included. Data were collected from the electronic medical record. Neonates with severe haemophilia were separated into two groups—those pretreated with one dose of factor replacement before circumcision and those without pretreatment. Results We observed that neonates with severe haemophilia pretreated with a single dose of factor VIII or factor IX replacement had significantly reduced bleeding complications, shorter hospital stay and required less therapeutic intervention compared with untreated patients. Importantly, pretreated patients had outcomes similar to healthy controls. Conclusions Our results demonstrate that a single dose of factor replacement before circumcision is effective to prevent bleeding in neonates with severe haemophilia.
