Echocardiographic abnormalities in very preterm babies requiring cardiorespiratory support- a prospective observational study

All preterm babies (less than 32 weeks of gestation) requiring cardiorespiratory support will be included in the study. Functional echocardiography will be performed by a neonatologist trained in cardiac echocardiography within 24 hours starting of cardiorespiratory support in the first week of life. Results of the echo will be confirmed by a pediatric cardiologist.Parameters like left ventricular output, right ventricular output, mitral valve EA ratio, fractional shortening, inferior vena cava collapsibility index, PDA assessment, tricuspid regurgitation, TAPSE and septal motion will be documented in each echo examination. Echo findings will be compared with the hemodynamic status of each baby at that point of time. If any abnormal echo findings is documented that baby will be followed up by a repeat echo after 24 hrs. Any change in management plan done based on the echocardiographic findings if done will also be noted. Unit.
