Abstract
Objectives: Lung ultrasonography (LUS) is increasingly used to assess pulmonary diseases due to its safety and convenience. This study aimed to find out the association between the LUS score and the PaO2/FiO2 ratio in neonatal pneumonia.
Methods: This study prospectively enrolled 57 neonates with suspected pneumonia. LUS score (range 0-48) was evaluated by assessing 12 lung regions. The PaO2/FiO2 ratio was calculated by dividing the arterial oxygen partial pressure by the fraction of inspired oxygen from blood gas analysis. Correlations were analyzed using Pearson's correlation coefficient.
Results: Birth weight ranged 1 100-4 500 g (median 2 925 g), gestational age 27-41 weeks (median 37 weeks), and age 1-28 days (median 1 day). The LUS score was significantly correlated with the PaO2/FiO2 ratio (r = 0.758, p < 0.001), arterial oxygen partial pressure (r = 0.731, p < 0.001), partial pressure of carbon dioxide (r = 0.213, p < 0.001), and oxygen saturation (r = 0.196, p < 0.001).
Conclusions: Our study demonstrates significant correlations between the LUS score and blood gas analysis indices in neonatal pneumonia.
期刊介绍：
The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography.
The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents.
JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
