Objective To compare the hemostatic effect of hemocoagulase vs. tranexamic acid in patients with craniocerebral trauma surgery. Methods In total,100 patients with craniocerebral trauma surgery were randomly divided into group A and group B (50 cases in each group). Group A was intravenously injected with tranexamic acid injection 0.25g+0.9% sodium chloride solution 250 mL from operation beginning to operation ending. Group B was intramuscularly injected with hemocoagulase 1U+0.9% sodium chloride solution 10 mL 30 min before the surgery,and intravenously injected with hemocoagulase 1 U+0.9% sodium chloride solution 250 mL from operation beginning to operation ending. Results The intraoperatve blood loss of group A and group B was (968.02±102.96),(726.97±81.42) mL,blood transfusion volume (735.12±74.24),(575.72±60.67) mL,drainage 24 h after the operation was (182.45±23.54),(150.22±18.47) mL. Re-bleeding rate was 16.00% and 2.00% (all P<0.05). According to the Glasgow Prognosis Score,good prognosis rate of group B (60.00%) was significantly higher than that of group A (40.00%) (P<0.05). The preoperative and postoperative prothrombin time (PT),activated partial thromboplastin time (APTT) and adverse reaction rates of the two groups were almost the same,and there was no thrombosis disease (P>0.05). Conclusion Compared with tranexamic acid,the hemostatic effect of hemocoagulase is better in patients with craniocerebral trauma operations,and it is helpful to avoid postoperative re-bleeding and improve the prognosis of patients.

Coagulopathy after traumatic brain injury (TBI) is a frequent event and is associated with patients' prognosis. TBI is also associated with a stress response that includes hyperglycemia. This study investigated if coagulopathy occurrence is associated with admission blood glucose levels in patients with TBI.This study retrospectively evaluated patients with TBI who were admitted to a neurosurgical department over a 4-year period. Coagulopathy was defined as an aPTT >40 seconds and/or INR >1.2 and/or a platelet count <120*10(9) per litre.One-hundred and forty-nine patients were included in the study. Thirty-four patients developed coagulopathy. Patients with coagulopathy had significantly lower haemoglobin levels, increased INR and increased aPTT. Patients with severe TBI had more frequent coagulopathy. Patients with severe TBI had significant higher serum glucose levels compared to patients with mild TBI. Using ROC curves it was found that a serum glucose of 15165mg65dl(-1) was the threshold for the discrimination of patients that developed coagulopathy. Logistic regression analysis revealed that serum glucose greater than 15165mg65dl(-1) and haemoglobin levels lower than 12.465mg65dL(-1) were significantly associated with coagulopathy occurrence.Coagulopathy frequently occur after TBI. Patients with lower GCS score and lower haemoglobin levels and increased blood glucose levels at admission are at greater risk.

Background: Intracranial amyloid and hypertensive angiopathy have been related to impaired blood vessel function and the etiology of intracerebral hemorrhage (ICH). Microbleeds (MBs) are surrogate radiological markers that are associated with these underlying angiopathies. We assessed the hypothesis that MBs are associated with hematoma expansion (HE) in patients with hyperacute ICH. Methods: We studied patients with spontaneous supratentorial ICH within the first 6 h after onset. HE was defined as an increase >= 33% in the volume of hematoma on the follow-up CT in comparison with the admission CT. The volume was calculated using the ABC/2 formula. MBs were detected by specific magnetic resonance sequences (gradient-echo). The presence, number and distribution of MBs were analyzed. Results: Our study included 44 patients. Their mean age was 68.9 +/- 11.1 years, and 70.5% of them were men. HE was observed in 14 of the patients (31.8%). HE was more prevalent in patients with more than 10 MBs compared with patients with 1-10 MBs (60 vs 12.5%; p = 0.03). Conclusion: A high burden of MBs is associated with an increased risk of HE in patients with ICH. This is probably a marker of a more severe underlying angiopathy. Copyright (C) 2013 S.

Abstract Intravenous tranexamic acid (TXA) has been identified to be effective in total knee arthroplasty (TKA), but the effect of topical application is still unclear. Therefore, the authors conducted a meta-analysis to assess the effect of topical TXA in TKA. Twelve trials with a total of 1179 knees were included. The results revealed that the application of topical TXA in TKA significantly reduced total blood loss by a mean of 280.65 mL and reduced transfusions without increasing the risks of deep venous thrombosis and pulmonary embolism. Topical TXA also reduced postoperative drain output by a mean of 194.59 mL and lowered postoperative hemoglobin drop by a mean of 0.66 g/dL. In addition, subgroup analysis showed that high-concentration TXA may be better at reducing bleeding and transfusions than low-concentration TXA. Therefore, the authors concluded that topical TXA can effectively reduce bleeding and transfusion rate in TKA without increasing the risk of deep venous thrombosis and pulmonary embolism, and high-concentration (20 mg/mL or more) topical TXA is recommended.
