目的:探讨头颅B超对新生儿颅脑损伤的诊断价值。方法:308例新生儿常规作头颅B超检查,其中68例窒息新生儿检查B超同时作头部CT检查,B超、CT、临床表现作比较。结果:B超提示新生儿缺氧缺血性脑病(HIE)改变为65例,阳性率为95.59%,CT提示HIE改变为29例,阳性率为42.65%,两组比较差异有统计学意义(χ2=0.18,P<0.01)。B超诊断为HIE 65例,临床有HIE症状者27例,有18例临床和CT均无表现,B超却有表现。结论:头颅B超为常规筛查新生儿早期有无颅内病变的首选诊断手段,探查缺氧缺血性脑病B超明显优于CT。
Objective: To investigate the diagnostic value of skull B-ultrasound in neonatal brain injury. Methods: A total of 308 newborns were examined by B-ultrasound. Among them, 68 asphyxiated newborns were examined by B-scan at the same time for head CT, B-ultrasound and CT, and clinical manifestations were compared. Results: B-mode ultrasound showed that the rate of neonatal hypoxic-ischemic encephalopathy (HIE) was 65 cases, the positive rate was 95.59%. CT showed that HIE was changed to 29 cases, the positive rate was 42.65%. There was significant difference between the two groups χ2 = 0.18, P <0.01). B ultrasound diagnosis of HIE 65 cases, clinical symptoms of HIE in 27 cases, 18 cases of clinical and CT showed no performance, B ultrasound has performance. Conclusion: B-ultrasound is the first choice for routine screening of neonates with or without intracranial lesions, and the detection of B-ultrasound of hypoxic-ischemic encephalopathy is superior to CT.
