目的分析重症肺炎合并呼吸衰竭新生儿的肺超声特点,为临床诊治提供参考。方法选择2014年12月至2015年8月入院并确诊为重症肺炎合并呼吸衰竭的新生儿,对患儿双肺十二区进行横向及纵向超声检查,观察患儿肺部超声改变并进行回顾性分析。结果共入选44例患儿。超声检查均有异常,主要表现为肺组织实变(41例)、出现B线(44例)、胸膜线异常(44例)、胸腔积液(3例)。双肺受累者32例占73%,十二区每区域均可出现病变,累及肺区数≥6区者(32例,占73%)。41例肺实变中,右后上区肺实变发生率最高(26例,占63%)。结论肺超声检查对新生儿重症肺炎合并呼吸衰竭患儿有重要的诊断价值,对肺实变部位及范围的评估可为临床治疗提供参考。
Objective To analyze the characteristics of pulmonary ultrasound in neonates with severe pneumonia complicated with respiratory failure and provide reference for clinical diagnosis and treatment. Methods Newborns admitted to hospital from December 2014 to August 2015 and diagnosed as severe pneumonia complicated with respiratory failure were selected. Lateral and longitudinal sonography was performed on the twelfth region of the double lung in children. The sonographic changes in the lungs were observed and retrospectively reviewed analysis. Results A total of 44 children were enrolled. Ultrasonography showed abnormalities. The main manifestations were lung consolidation (41 cases), B line (44 cases), abnormal pleural line (44 cases) and pleural effusion (3 cases). 32 cases of bilateral lung involvement accounted for 73%, 12 districts may appear lesions in each area, involving more than 6 areas of lung count (32 cases, 73%). In 41 cases of lung consolidation, the highest incidence of pulmonary consolidation occurred in the upper right area (26 cases, 63%). Conclusion Pulmonary echocardiography has important diagnostic value in neonates with severe pneumonia and respiratory failure. Evaluation of the location and extent of pulmonary consolidation can provide reference for clinical treatment.
