- Abstract
Thus, a patient who is dyspnoeic will tend to have a disproportionate collapse of the IVC, contrary to a patient who is hardly breathing, resulting in minimum collapse of an "empty" IVC. IVC measurement is less reliable and less accurate in M-mode when compared to B-mode.[[19]] The reliability is poorer in spontaneously breathing patients as it is difficult to standardise the tidal volume and respiratory efforts across spontaneously breathing patients. Intraoperative hypotension is a common occurrence in patients undergoing surgery under general and spinal anaesthesia and is associated with adverse outcomes.[[1]] Though its origin is multifactorial, one of the common modifiable causes is absolute or relative fluid deficit which can be treated with a fluid challenge to increase the cardiac output.
