Comparing the tissue Doppler-derived left ventricular myocardial performance index before and after recovery from respiratory distress in neonates: A prospective observational study.

Background And Objective: Respiratory distress is the most common cause requiring neonatal intensive care unit admission. As respiratory and cardiac functions are closely interrelated, some cardiac dysfunction is expected in respiratory distress. The myocardial performance index (MPI) is an index to assess global myocardial function, easily measurable by bedside echocardiography and reliable.

Plethysmograph Variability Index Values in Healthy Neonates - An Observational Pilot Study.

Objectives: To establish normative data of plethysmograph variability index (PVI), a simple non-invasive tool to measure fluid responsiveness, in neonates.

Methods: All healthy term and late preterm neonates were enrolled. PVI was recorded by pulse-oximeter on first three days of life along with other vital parameters.

Correlation of Plethysmograph Variability Index with Inferior Vena Cava Index in Spontaneously Breathing Neonates - A Cross Sectional Study.

Inferior vena cava (IVC) indices are commonly used to assess the need for fluid bolus during shock. It needs expertise and is difficult to do during surgical procedures. Plethysmograph variability index (PVI) is a simpler non-invasive tool used to measure fluid responsiveness in adults.
