目的 验证与探讨Besson评分法对急性脑卒中的早期诊断价值。方法 从 1998年 7月 1日～9月 30日住院的 91例急性脑卒中病人 ,全部病人均经CT或 /和MRI确诊。记录一般资料及Besson评分法中相应 8个变量 ,应用SPSS软件包进行统计学分析。结果 双变量分析发现TIA较常见于非出血性脑卒中 ,而巴彬斯基征和头痛较常见于出血性脑卒中 ;Besson评分有 2 0例Z <1,所有这些病人CT或 /和MRI诊断为非出血性脑梗死 ,占非出血性脑梗死的 38.46 % ,95 %的可信限为 2 8.46 %～ 48.46 % ;占总数的2 1.98% ,95 %可信限为 13.47%～ 30 .49% ;对非出血性脑梗死的阳性预告值为 10 0 % ,95 %的可信限为83%～ 10 0 %。结论 TIA史在非出血性脑梗死中常见 ,而巴彬斯基征和头痛常见于出血性脑卒中 ;38.46 % (95 %的可信限为 2 8.46 %～ 48.46 % )的非出血性脑梗死能够早期准确诊断 ,阳性预告值为 10 0 %(95 %的可信限为 83%～ 10 0 % )。Besson量表简单 ,计算方便 ,与CT(MRI)符合率高。
Objective To verify and explore the value of Besson’s score in the early diagnosis of acute stroke. Methods From July 1 to September 30, 1998, 91 acute stroke patients were hospitalized. All the patients were diagnosed by CT or / and MRI. Record the general information and Besson scoring method in the corresponding eight variables, using SPSS software package for statistical analysis. Results Bivariate analysis found that TIA was more common in non-hemorrhagic stroke, while Babinski’s sign and headache were more common in hemorrhagic stroke; Besson score had 20 Z <1 and all of these patients had CT or / and MRI diagnosis For non-hemorrhagic cerebral infarction accounted for 38.46% of non-hemorrhagic cerebral infarction, 95% of the confidence limits of 2 8.46% ~ 48.46%, accounting for 2 1.98% of the total 95% confidence interval was 13.47% ~ 30.49 %; The positive predictive value for non-hemorrhagic cerebral infarction was 10 0%, and the 95% confidence limit was 83% ~ 100%. Conclusion History of TIA is common in non-hemorrhagic cerebral infarction, while Babinski’s sign and headache are common in hemorrhagic stroke. In 38.46% (95% confidence interval, 2 8.46% -48.46%), non-hemorrhagic cerebral infarction Accurate early diagnosis, positive predictive value of 10 0% (95% confidence interval of 83% to 100%). Besson scale is simple, easy to calculate, and high coincidence rate with CT (MRI).
