title: Platelet function in the peri-operative period.
abstract: Although platelets have an important role in haemostasis and in thrombosis, what happens to platelet function postoperatively is not well understood. We investigated platelet function in the peri-operative period by measuring total platelet count and several products released by activated platelets, thromboxane, betathromboglobulin and lyso-platelet activating factor (lyso-PAF). The only changes detected were a significant rise in total platelet count between 48 h and 5 days post-operation, and a progressive fall in lyso-PAF up to 48 h post-operation. It is possible that other changes may have occurred, but were an immediate effect and were not apparent at time of the first blood sample 2-3 h post-operation.
