Aim: The study investigated the direct effects of tramadol on the coagulation status of women with gynecologic malignancies in vitro.
Materials and Methods: Citrated whole-blood samples from 21 patients with gynecologic tumors were spiked ex vivo with 2 or 6 μl/ml tramadol. Thrombelastography (TEG) analysis was performed using ROTEM® to assess clotting time (CT), clot formation time (CFT) and maximum clot formation (MCF).
Results: In the INTEM assay, CT (P < 0.05) and CFT (P < 0.01) were significantly prolonged with tramadol at a 6 μl/ml concentration compared with baseline. There were no significant differences in MCF values between the baseline and the tramadol-treated samples (P > 0.05). Blood medicated with tramadol (6 μl/ml) clotted slowly (increased CT and CFT).
Conclusion: The changes observed by TEG demonstrated that tramadol impairs hemostasis in a concentration-dependent manner in the whole blood of women with gynecologic malignancies in vitro.
