Fig. 3From: Comparison of blood loss between tranexamic acid-soaked absorbable Gelfoam and topical retrograde injection via drainage catheter plus clamping in cervical laminoplasty surgeryPerioperative coagulation panels in the three study groups. No significant differences were detected among the three groups for the prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR) or blood platelet count (PLT) on four perioperative time points, but in the TXA-RI and TXA-Gel groups, the D-dimmer (DD) and fibrinogen (FIB) were significantly lower than those in the control group after surgery. * P < 0.05Back to article page
