Abstract P-588: TO STUDY THE CORRELATION BETWEEN CHEST RADIOGRAPH AND LUNG SONOGRAPHY IN CHILDREN ADMITTED TO PEDIATRIC INTENSIVE CARE UNIT

Abstract

Aims & Objectives: To correlate the findings of CXR and lung USG in patients admitted to the PICU Methods Design: ProspectiveIt was prospective, double-blinded, observational study. Setting: Multidisciplinary which was conducted in multidisciplinary PICU at quaternary care children’s hospital, Delhi. Participants: All Children between (1month-18years) admitted in PICU. 413 patients were enrolled, with 1002 episodes, over 10 months. .Findings of lung USG performed by a pediatric intensivist, trained in point-of-care ultrasonography and blinded to CXR findings, were analyzed zone-wise. All CXR were reported by an experienced radiologist who was blinded to lung USG findings Results Of the 1002 observations, 451 exhibited a normal ultra-sonographic examination, and lung USG for different zones, irrespective of pathology was >60%. Accuracy of USG in detecting pneumothorax in upper zones and atelectasis in lower zones bilaterally was 100%. For512 had a normal chest radiograph. Different lung pathologies such as pulmonary edema and, pneumothorax, pleural effusion, the Sn and Sp was >90% and >95%, respectively.consolidation and collapse were detected by the two modalities. USG lung diagnosed pulmonary edema in 111/281(39.5%) episodes where CXR was reported normal (Chi- square: statistic 81.7, P<0.05),). Similarly, pneumothorax was not observed in CXR in 9/41 (22%) episodes with positive USG findings (Chi- square: statistic 12.3, P<0.0003) and pleural). Pleural effusion was detected in 102/275 (37%) episodes (Chi-square:28.1,P<0.005) without any supportive evidence from CXR. (Chi square statistic 28.1, P<0.005). (figure 1) Conclusions USG is atleastat least equal or probably better modality than CXR for diagnosing different lung pathologies in PICU
