摘 要:目的应用掌上超声诊断仪对急诊疑似心脏疾病的患者进行初步诊断,评价掌上超声诊断仪在急诊中的应用价值。方法选取2016年6—12月在北京市第六医院急诊科就诊的疑似心脏疾病患者240例。应用美国GE Vscan型掌上超声诊断仪,由2名接受培训的急诊科医师进行床旁超声心动图检查,评估房室内径及室壁厚度、有无心包积液及程度、有无节段性室壁运动异常、左心室收缩功能情况、瓣膜病变情况。所有患者均在掌上超声诊断仪检查之后,再由超声科医师应用美国GEVividE9型超声心动仪进行检查。采用Kappa系数评估2种仪器诊断结果的一致性,以及上述2名不同医师使用掌上超声诊断仪诊断结果的一致性。结果掌上超声诊断仪诊断结果示:房室扩大76例,室壁增厚21例,节段性室壁运动异常36例,左心室收缩功能减低27例,瓣膜反流92例,心包积液4例。进行一致性分析,结果显示掌上超声诊断仪与普通超声心动仪诊断结果的一致性较高[Kappa系数(95%置信区间):房室扩大0.83(0.75—0.90),室壁增厚0.88(0.76—0.97),节段性室壁运动异常0.82(0.70—0.91),左心室收缩功能减低0.87(0.76~0.96),瓣膜反流0.83(0.75~0.89),心包积液1.00(1.00~1.00)];二者检查结果的不一致均体现在轻度异常的患者,对临床诊断和治疗无明显影响。2名医师之间诊断结果的一致性也较高[Kappa系数(95%置信区间):房室扩大0.94(0.89—0.98),室壁增厚0.92(0.82~1.00),节段性室壁运动异常0.87(0.76—0.95),左心室收缩功能减低0.85(0.73—0.95),瓣膜反流0.94(0.90~0.98),心包积液1.00(1.00~1.00)]。结论对于急诊疑似心脏疾病的患者,掌上超声诊断仪能够快速、准确地评价心脏解剖结构、功能及血流动力学状态Objective To evaluate the diagnostic value of handheld echocardiography for heart diseases in Department of Emergency. Methods Totally 240 patients with undiagnosed heart diseases who were admitted to Department of Emergency of Beijing No. 6 Hospital from June 2016 to December were enrolled. GE Vscan handheld ultrasonic diagnostic equipment was used for emergency bedside echocardiography by 2 trained doctors; evaluating indexes included cardiac atrioventrieular diameters and wall thicknesses, pericardial effusion, regional wall motion abnormality, left ventricular systolic function and valvular lesions. GE Vivid E9 echocardiography was used for confirmed diagnosis of heart diseases. Consistencies of diagnostic results from 2 instruments and 2 doctors were analyzed. Results The handheld echoeardiography showed 76 cases of atrioventricular enlargement, 21 cases of ventricular wall thickening, 36 cases of regional wall motion abnormality, 27 cases of left ventrieular systolic dysfunction, 92 cases of valvular regurgitation and 4 cases of pericardial effusion. There was a good consistency between diagnostic results of GE Vscan handheld eehocardiography and GE Vivid E9 eehoeardiography [ Kappa coefficient( 95% confidence interval) : atrioventricular enlargement 0. 83 ( 0. 75-0. 90 ) , ventricular wall thickening 0. 88 ( 0. 76-0. 97 ), regional wall motion abnormality 0. 82 ( 0. 70-0. 91 ) , left ventricular systolic dysfunction 0. 87 ( 0. 76-0. 96 ), valvular regurgitation 0. 83 ( 0. 75-0. 89 ), perieardial effusion 1.00 (1.00-1.00) ]. The consistency between 2 doctors was good [ Kappa coefficient ( 95% confidence interval ) : atrioventrieular enlargement 0.94(0.89-0.98), ventricular wall thickening 0.92(0.82-1. 130), regional wall motion abnormality 0.87 (0.76-0.95), left ventricular systolic dysfunction 0.85 ( 0.73-0.95 ), valvular regurgitation 0.94 (0. 90-0. 98 ) , pericardial effusion 1.00 (1.00-1.00) 1. Conclusion Handheld echocardiography can accuratel
