急诊床边超声对修正的Geneva评分中度患者肺栓塞的预测价值

目的回顾性分析急诊床边超声在修正的Geneva评分低中高度患者肺栓塞的诊断价值,减少肺栓塞误诊漏诊,提高肺栓塞的早期诊断率。方法收集1999—2010年10月本院可疑肺栓塞112例,其中临床确诊肺栓塞75例,分析修正的Geneva评分及超声结果。据修正的Geneva评分分为低、中、高危组,每组分为超声阳性与超声阴性对照组,分别计数确诊肺栓塞与非肺栓塞人数,SPSS 15.0软件进行统计分析,计数资料组间比较采用卡方检验或FISHER精确概率法分析,以P<0.05为差异具有统计学意义。结果肺栓塞可能性分别与Geneva评分(χ2=38.6862.P<0.0001)高低有关,具有统计学意义。超声阳性与超声阴性对照组分别对应的肺栓塞与非肺栓塞人数在Ge-neva评分低组(P=0.2120)及高组(P=1.0000)无统计学意义,在中组超声阳性确诊肺栓塞的可能性大于超声阴性,(P=0.0235)有统计学意义。结论修正的Geneva评分中度患者床边超声检查可增加确诊肺栓塞的可能性,减少肺栓塞误漏诊,提高肺栓塞的早期诊断率。

Predication of bedside ultrasound in modified group of revised Geneva scores for pulmonary embolism in mergency

Objective To reduce misdiagnosis and underdiagnosis rate of pulmonary embolism,increase early diagnosis rate,the prediction of the emergency bedside ultrasound in the revised Geneva score low、 modified and high groups were retrospectively analyzedMethods One-hundred-twelve cases with suspected pulmonary embolism（PE）were collected in our hospital from October 1999-October 2010,Of which 75 cases with PE were clinically confirmed.Results clinical data were recorded.evaluate the probability of PE predicted by the revised Geneva scores,According to the revised Geneva score is divided into low,medium and high risk groups and each group is divided into ultrasound positive and negative,the number with the pulmonary embolism and non-pulmonary embolism were counted.Relevant clinical data were recorded.summarized and the analysis variables were input to SPSS15.0 for statistical analysis.P〈0.05 for a statistically significant difference.Results：pulmonary embolism possibility has reletive with the Geneva score（χ2=38.6862.J P〈0.0001）.Predication of ultrasound positive and negative in low and high risk groups have no statistical difference.in modified group,the prediction of pulmonary embolism in positive ultrasonic diagnosis is superior han the ultrasound negative（P=0.0235）,with a statistical difference.Conclusion bedside ultrasound can Increase the possibility of Predication ofpulmonary embolism in modified groups of the revised Geneva score
