摘要
目的探讨肺部超声对新生儿暂时性呼吸困难(TTN)的早期诊断价值。方法选择我院新生儿科收治的临床表现为呼吸困难的新生儿80例,根据临床诊断结果将新生儿分为TTN组57例和呼吸窘迫综合征(RDS)组23例,均行肺部超声和胸片检查,并比较其结果,以临床诊断结果为金标准,比较超声和胸片对TTN的诊断效能。结果TTN组和RDS组新生儿在胸膜线异常、白肺征、双肺点、肺泡-间质综合征和肺实变所占比例比较差异均无统计学意义。以临床诊断结果为金标准,肺部超声诊断TTN的敏感性、特异性、阳性预测值、阴性预测值和准确率分别为94.74%、95.65%、98.18%、88.00%和95.00%;胸片诊断TTN的敏感性、特异性、阳性预测值、阴性预测值和准确率分别为84.21%、82.61%、92.31%、67.86%和83.75%。肺部超声诊断TTN的敏感性、特异性、阳性预测值和阴性预测值均高于胸片,但差异均无统计学意义;准确率明显高于胸片,差异有统计学意义(P<0.05)。结论肺部超声对新生儿TTN的早期诊断价值显著,值得临床推广应用。
Objective To explore the early diagnostic value of lung ultrasound in transient tachypnea in newborns(TTN).Methods A total of 80 neonates with dyspnea admitted to neonatology department in our hospital were selected.According to the clinical diagnosis results,the neonates were divided into TTN group(n=57)and respiratory distress syndrome(RDS)group(n=23).Lung ultrasonography and chest X-ray were performed on all neonates,and the results were compared.The clinical diagnosis results were used as the gold standard,the diagnostic efficiency of ultrasound and X-ray on TTN were compared.Results The proportions of abnormal pleural line,white lung sign,double lung point,alveolar interstitial syndrome and pulmonary consolidation between TTN group and RDS group showed no statistically significant differences.Taken clinical diagnosis results as the golden standard,and the sensitivity,specificity,positive predictive value,negative predictive value and accuracy of lung ultrasound in the diagnosis of TTN were 94.74%,95.65%,98.18%,88.00%and 95.00%,respectively.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of X-ray in the diagnosis of TTN were respectively 84.21%,82.61%,92.31%,67.86%,83.75%,respectively.The sensitivity,specificity,positive predictive value,negative predictive value of lung ultrasound in the diagnosis of TTN were higher than those of X-ray,but the differences were no statistically significant.The accuracy of lung ultrasound in the diagnosis of TTN was obviously higher than that of X-ray,and the difference was statistically significant(P<0.05).Conclusion Lung ultrasound has significant value in the early diagnosis of TTN,which is worthy of clinical application.
