Abstract:
Superior vena cava is commonly used in neonatal hemodynamics and is suggested to be the best available non-invasive marker for systemic circulation in preterm infants. Inter- and intra-observer variability remain to be an issue. Its association with neonatal outcomes is has not been established. This is a narrative review about this marker, its use, and its potential pitfalls.
Objective:
This is a narrative review about SVC flow in preterm infants, physiology, techniques of measurement and its potential association with outcomes.
Sources:
Literature revie mainly PubMED.
Summary Of The Findings:
SVC flow measurement has some limitations and pitfalls.
Conclusions:
SVC flow association with neonatal outcomes, still needs to be established in further research.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
