Heat injury is a common, potentially life-threatening medical condition. In austere or mass-casualty conditions an easy to use, sensitive screening test could be a valuable tool to care providers and evacuation planners.
The objective of the study was to determine if a simple urine dipstick test for blood is sensitive for detection of rhabdomyolysis in the suspected heat injury patient.
A convenience sample of patients presenting to a military community hospital Emergency Department during summer months with a presenting complaint consistent with suspected heat injury had urine dipstick testing performed for blood and compared with the results of formal urinalysis and serum creatine kinase.
60 patients were enrolled in the study, seven had creatine kinase levels greater than 1000 U/L, 14 had levels greater than 500 U/L, and 26 had levels greater than 250 U/L. Using 1000 U/L, urine dipstick testing had a sensitivity of 14% and a specificity of 85%.
Urine dipstick testing for blood is not a useful screening test for rhabdomyolysis in patients suspected to have significant heat injury.
热损伤是一种常见的、可能危及生命的医学状况。在严峻或大规模伤亡情况下，一种易于使用且灵敏的筛查测试对于医护人员和疏散规划者而言可能是一种有价值的工具。
本研究的目的是确定一种简单的尿液潜血试纸检测对于疑似热损伤患者横纹肌溶解症的检测是否灵敏。
选取夏季期间到一家军队社区医院急诊科就诊、主诉符合疑似热损伤的患者作为便利样本，对其进行尿液潜血试纸检测，并与正规尿液分析及血清肌酸激酶的结果进行比较。
60名患者纳入本研究，7名患者的肌酸激酶水平高于1000 U/L，14名患者高于500 U/L，26名患者高于250 U/L。以1000 U/L为标准，尿液潜血试纸检测的灵敏度为14%，特异性为85%。
对于疑似有严重热损伤的患者，尿液潜血试纸检测并非横纹肌溶解症的有效筛查测试。
