Background: It was hypothesized that patients who are preload dependent, as demonstrated by a >12% increase in cardiac output in response to a passive leg raise test, would be more likely to exhibit hypotension during spinal anesthesia for cesarean delivery.
Methods: Cardiac output response to the passive leg raise test was measured in 40 women before spinal anesthesia with a noninvasive, continuous cardiac output monitor (NICOM®). Patients were divided into two groups based on their performance on the passive leg raise test; those who increased cardiac output >12% following passive leg raise test were considered fluid responsive.
