【摘要】：目的探讨近红外光谱(NIRS)检测对硬膜外及硬膜下血肿的临床应用价值。方法选取34例经CT或MRI证实的硬膜外或硬膜下血肿患者(试验组)及14名健康志愿者(对照组),采用中国科学院自动化研究所研发的NIRS设备进行头部检测,评判是否存在颅内出血。以CT或MRI诊断结果为"金标准",评价NIRS对硬膜外及硬膜下血肿的诊断效能。结果 NIRS诊断硬膜外及硬膜下血肿的敏感度、特异度、准确率、阳性预测值及阴性预测值分别91.18%(31/34)、71.43%(10/14)、85.42%(41/48)、88.57%(31/35)及76.92%(10/13)。结论 NIRS在检测硬膜外及硬膜下血肿方面具有较高的敏感度和阳性预测值,有助于临床早期诊断和治疗。
[Abstract]:Objective to evaluate the clinical value of NIR spectroscopy in the detection of epidural and subdural hematoma.Methods 34 patients with epidural or subdural hematoma confirmed by CT or MRI (experimental group) and 14 healthy volunteers (control group) were selected for head examination using NIRS equipment developed by Institute of Automation, Chinese Academy of Sciences.The presence of intracranial hemorrhage was assessed.The diagnostic efficacy of NIRS in the diagnosis of epidural hematoma and subdural hematoma was evaluated by CT or MRI.Results the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of NIRS in the diagnosis of epidural and subdural hematoma were 91.18 / 31 / 34 and 71.43 / 14 respectively.Conclusion NIRS has high sensitivity and positive predictive value in the detection of epidural hematoma and subdural hematoma, which is helpful for early clinical diagnosis and treatment.
