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。Objective To explore the application value of near-infrared spectrum （NIRS） in the detection of epidural and subdural hematoma in clinic. Methods Thirty-four patients with subdural and epidural hematomas （study group） confirmed by CT or MRI and 14 healthy volunteers （contrast group） were selected. The NIRS equipment which was produced by Institute of Automation of Chinese Academy of Sciences were used to assess the intracranial hematomas. Taking CT or MRI results as the golden standard, the diagnostic efficiency of NIRS for subdural and epidural hematomas were evaluated. Results For the diagnosis of subdural and epidural hematomas, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 91.18%（31/34）, 71.43%（10/14）, 85.42%（41/48）, 88.57%（31/35） and 76.92% （10/13）, respectively. Conclusion NIRS is a good device to predict intracranial subdural and epidural hematomas with high sensitivity and positive predictive value, which is helpful for early diagnosis and therapy in clinic.
