The utility of Traube's space percussion in the bedside assessment of splenic enlargement was evaluated. The influence of meals and obesity on this sign were also assessed, because both are believed to interfere with the results of abdominal percussion.
The inpatient population of a tertiary care hospital was studied where cases and controls were selected according to the results of abdominal ultrasonographic examinations.
Traube's space percussion exhibited a sensitivity of 0.62 (95% confidence interval [CI], 0.51 to 0.71) and a specificity of 0.72 (95% CI, 0.65 to 0.80) when classifying tympanitic examinations as negative. False-positive examinations were reduced by assessing patients more than two hours after mealtime. Obese patients were a source of false-negative examinations.
Traube's space percussion compares favorably with other commonly used clinical maneuvers and diagnostic tests. When performed alone in a selected patient population, it adds useful clinical information but is not sufficiently sensitive or specific to obviate the need for further diagnostic testing.
评估Traube间隙叩诊在床边评估脾脏肿大中的效用。还评估了进餐和肥胖对该体征的影响，因为二者均被认为会干扰腹部叩诊结果。
对一家三级护理医院的住院患者进行研究，根据腹部超声检查结果选择病例和对照。
将鼓音检查判定为阴性时，Traube间隙叩诊的灵敏度为0.62（95%置信区间[CI]，0.51至0.71），特异度为0.72（95%CI，0.65至0.80）。进餐两小时后对患者进行评估可减少假阳性检查。肥胖患者是假阴性检查的一个来源。
Traube间隙叩诊与其他常用的临床操作和诊断测试相比具有优势。在选定的患者群体中单独进行时，它可提供有用的临床信息，但灵敏度和特异度不足以排除进一步诊断测试的必要性。
