Purpose: The aim of this study is to compare the trombocytes index in late premature newborns and term newborns and to study the relationship with perinatal factors. Tools and Methods: 98 late pre-term and 102 term newborn retrospective, which were accepted in the Newborn Intensive Care Unit of an academic center between 2018-2020, were assessed as retrospective. The blood samples taken on the first day of life were measured with trombocytes, including the number of trombocytes (PLT), the average volume of trombocytes (MPV), the plateletcrit (PCT) and the thrombotic distribution width (PDW). Results: There was no significant difference between late premature and term newborns in terms of PLT, MPV, PCT and PDW values. In late premature newborns, multi-variable analysis showed that maternal hypertension was significantly associated with low PLT (p=0.001). In newborns, the multi-variable analysis showed that being young to pregnancy age (SGA), male and maternal hypertension were significantly associated with low PLT (respectively p<0.001, p=0.001 and p=0.017). Moreover, SGA and male sex were associated with lower PCT (p = 0.001). In all the patients studied, MPV was significantly different between babies with and non-PROM (9.8fL and 9.2fL, p = 0.001). Discussions and Results: The results obtained show that various perinatal characteristics affect the trombocytes index of late preeterm and term newborns.
