256例急诊头晕患者临床特点分析

Clinical Characteristics Analysis of 256 Emergency Dizzy Patients

目的:分析急诊头晕患者的病因,探讨其临床特点,提高临床诊断水平。方法:收集2014年1-12月于笔者所在医院急诊科就诊的256例头晕患者的临床资料,将患者分为老年组和非老年组,分析急诊头晕的病因与临床特点。结果:非老年组以良性位置性眩晕(BPPV)发病率最高,老年组以后循环缺血(PCI)等中枢神经系统病变常见。不同年龄组在经颅多普勒超声(TCD)检查中血流变化情况比较,差异均有统计学意义(P<0.05)。结论:急诊头晕病因复杂,临床表现多样。青中年头晕患者首先考虑BPPV、精神因素及高血压病等。老年头晕患者主要以后循环缺血等中枢系统疾病为主,且在TCD检查中多伴有血流速度异常。

Objective:To explore the causes of emergency dizziness,discuss the clinical characteristics and improve the diagnostic efficiency. Method:The clinical data of 256 dizziness patients in our emergency department from January 2014 to December 2014 were included,they were divided into the elder group and non-elder group,the etiology and clinical characteristics of emergency dizziness were analyzed.Result:The main causes in non-elder group was BPPV(52.7%),the main causes in elder group was PCI(41.7%)and other central nervous system diseases.Different age groups in transcranial doppler ultrasound(TCD) of the changes in the blood flow were compared,the differences were statistically significant(P<0.05).Conclusion:Emergency dizziness etiology is complex,clinical manifestations of a variety of young and middle-aged dizziness patients first consider BPPV,mental factors and hypertension and so on.Elderly patients with dizziness mainly after the circulation ischemia(PCI) and other central nervous system diseases,and in the TCD examination and more with abnormal blood flow.
