Relation and prevention between aspirin and relapsing haemorrhage after operation in cerebral haemorrhage patients

Objective To explore the relation and measures prevention between aspirin and relapsing haemorrhage after operation in cerebral haemorrhage patients. Method It' s a prospective control study. A total of 725 patients with hypertensive basal ganglia cerebral haemorrhage admitted to department of neurosurgery from January 2001 to May 2007 were enrolled. They were diagnosed according to the diagnostic criteria set by the fourth national cerebrovascular disease conference in 1995. Haematoma volume was ＞ 50 mL. All patients were treated with craniotomy. And those with respiration and circulation failure, neurologic function deficit before the onset of the disease,major organ dysfunction, haemorrhagic disease and bleeding tendency or applied medicines affecting coagulation function excepted aspirin were excluded. The patients without use of aspirin before the onset of the disease were operated as the control group(group A), and there were 389 patients in group A.The patients with use of aspirin before the onset of the disease were randomly assigned to group B and C group,and there were 168 patients in group B or group C.The patients in group C received the frozen apheresis platelets. We counted different haematoma volume of relapsing haemorrhage after operation,death rate,ADL scores grades by 6 months follow-up survey in three groups. Quantitative data were expressed as mean ± standard deviation (-x ± s). The data were analyzed by using Chi-square test and Student's t test and rank sum test with SPSS 13.0 statistical package. A P value less than 0.05 indicated statisticals significance. Results Haematoma volume of relapsing haemorrhage was (40.59 + 20. 061 )mL, (53.21 ± 21.260) mL, (40.68 ± 19.517) mL in groups A, B, C,respectively. There was significant difference between group A and group B ( P ＜ 0.01 ), between group B and group C ( P ＜ 0.05), but there was no significant difference between group A and group C(P ＞ 0.05). ADL scores grades at 6-month follow-up was (67.04 ± 26. 176), (54.47 ± 29.403 ), (68.21 ± 25.254) in groups A, B, C, respectively. There was more significant difference between group A and group B, in ADL scores grades and the death rate between group B and group C (P ＜ 0.01), but there was no significant difference between group A and group C (P ＞ 0.05). Conclusions Aspirin can increase the occurrence rate of haemorrhage after operation, disablement and death in cerebral haemorrhage patients, but frozen apheresis platelets can reduce the occurrence rate.
