Platelet transfusions are widely administered to restore perioperative haemostasis in haemorrhagic patients; however, the role of platelet transfusion is not well understood and administration is often based on empiric data. This review aims to explore consensus regarding platelet transfusion trigger, dose and how the haemostatic efficacy of platelet transfusion was assessed for the treatment of perioperative bleeding. ⋯ The lack of consensus in published studies hinders our ability to draw conclusions regarding platelet transfusion and highlights the need for further studies to assess the appropriate dose and triggers for use in perioperative patients.
