Use of Inferior Venacaval Collapsibility Index in Spinal Anesthesia during Orthopedic Surgeries.

Background: Volume deficit is one of the predictors of hypotension. Inferior venacaval collapsibility index (IVCCI) can detect volume deficit and aids volume resuscitation in patients of intensive care unit.

Aims: The primary aim was to compare the incidence of postspinal anesthesia hypotension (PSAH) in IVCCI measured and nonmeasured groups.
