Advancing, strengthening and reshaping obstetric critical care with Point-of-Care Ultrasound (POCUS)

© 2021 Indian Journal of Anaesthesia | Published by Wolters Kluwer Medknow It has been hypothesised since the early 18th century by Spallanzani that sound beyond the reach of human ears is used by bats to navigate.[1] As with most other discoveries, this was first put to use for military purposes by the United States navy during the world wars. The first medical use came much later in the second half of the 20th century when Ian Donald used it for medical purposes in obstetrics and gynaecology. The first ultrasonography (USG) machines were developed in the 1950s, whereas limited, experimental use began not earlier than the 60s. It was in the 1970s that USG started being widely used for various clinical specialities, mainly as a diagnostic tool.[2]
