Background: Premature infants are predisposed to coagulopathy, which may increase intraventricular haemorrhage (IVH). Coagulation values vary by gestation in utero and are different to term values. Limited data exists in literature for coagulation parameters < 26/40 GA. Conservative estimates increase unnecessary blood products, while untreated coagulopathy could increase IVH.Aim: Describe distribution of day 1 PT, APTT and Fibrinogen for infants < 26/40 GA.Methods: Retrospective review of infants (< /= 26/40 GA) between 1.1.2004-31.12.2010. Clotting studies performed on < 26/40 GA in our hospital on day 1 of life. Values obtained from computerised laboratory system. Descriptive statistics performed.Results: Clotting values summarised in Table 1. Cases were excluded if value exceeded laboratory measurement capability (n=6) or not obtained on day 1.*Narrowing of range between 23-26 /40 GA**Laboratory reference range: PT 13.0+/-1.43, APTT 42.9+/- 5.8, FBG 2.83+/-0.58Conclusions: Term reference ranges differ from coagulation values for < 26/40 GA. This large cohort provides normative values for interpretation of day 1 coagulation values. Further studies required to determine whether treatment of raised coagulation values is of therapeutic benefit.
