Abstract

We aim to test the changes of coagulation parameters after the TBI by thromboelastography. Eleven patients who underwent TBI between march 2005 and march 2006 in our department were included in this study. Blood samples were taken from all patients immediately before the delivery of TBI and 12 hours after the completion of TBI. Complete blood counts, partial thromboplastin time (aPTT), prothrombin time (PT), and the fibrinogen levels were measured. FIB-EXTEM, extrinsic (TEG-EXTEM), intrinsic (TEG-INTEM) clotting pathways, and platelet functions were measured by rotational thromboelastogram (ROTEM). All measured parameters were compared by using wilcoxonpaired test. There was no difference in the PT, aPTT, thrombin and thrombocyte counts before and after TBI. However, maximum clot firmness was decreased after TBI in FIBTEM measurement (18.6 vs 15.5, p<0.05). The clot formation time was also significantly prolonged (115.8 vs 121.7 seconds, p<0.05 ) and maximum clot firmness was decreased in EXTEM measurements. The fibrinogen levels were significantly decreased after TBI. Our results demonstrated that the clot formation was significatly decreased in the early period after TBI. Prolongation of clot formation time and decrease in maximum clot firmness in extrinsic pathway after TBI indicates disturbance in platelet functions.

Özet

Bu çalışmanın amacı TBI uygulanan hastalarda koagülasyon parametrelerindeki değişiklileri tromboelastografi yöntemi ile araştırmaktır. Mart 2005 ve Mart 2006 tarihleri arasında bölümümüzde TBI uygulanan 11 hasta çalışmaya dâhil edilmiştir. Kan örnekleri TBI’dan hemen önce ve TBI’dan 12 saat sonra alınmıştır. Tam kan sayımı, parsiyel tromboplastin zamanı (aPTT), protrombin zamanı (PT) ve fibrinojen seviyeleri ölçülmüştür. FIB-EXTEM, ekstrinsik (TEG-EXTEM), intrinsik (TEG-INTEM) pıhtılaşma yolakları ve trombosit fonksiyonları rotasyonal tromboelastogram (ROTEM) ile değerlendirilmiştir. Bütün ölçümler wilcoxon-paired test kullanılarak karşılaştırılmıştır. PT, aPTT, trombin ve trombosit değerlerinde TBI’dan önce ve sonra yapılan ölçümlerde bir fark saptanmamıştır, ancak FIBTEM ölçümlerinde maksimum pıhtı sağlamlığının TBI’dan sonra azaldığı gözlenmiştir (18.6 vs15.5, p<0.05). Pıhtı oluşum zamanı belirgin uzamıştır (115.8 vs 121.7 saniye, p<0.05) ve masimum pıhtı sağlamlığı EXTEM ölçümlerinde azalmıştır. TBI’dan sonra fibrinojen düzeyleri belirgin azalmıştır. Sonuçlarımız TBI’dan sonraki erken dönemde pıhtı oluşumunun belirgin azaldığını göstermektedir. Pıhtı oluşma zamanının uzaması ve ekstrinsik yolakta maksimum pıhtı sağlamlığının azalması TBI’dan sonra trombosit fonksiyonlarının bozulduğunu göstermektedir.
