This study aimed to determine the predictive value of intercostal and pulmonary artery Doppler flow patterns in the outcome of childhood pneumonia. Pneumonia was classified according to type of pleural effusion and the ultrasound features of consolidations. Doppler flow patterns of intercostal and pulmonary arteries were analysed and correlated with pneumonia type and hospital stay. Of 83 pneumonia cases, 55 were uncomplicated and 28 were complicated. Pleural effusion was present in 54 cases, with 29 non-septated and 25 septated cases. Patients with uncomplicated pneumonia did not have abnormal Doppler flow patterns, compared with 64% (18 of 28) of patients with complicated pneumonia. Doppler ultrasound patterns in childhood pneumonia were correlated with pneumonia type and may be predictive of pneumonia outcome.
