Outcome Measures

Primary Outcomes (1)

  • Correlation between baseline PVI and change in SBP from baseline.

    Correlation between baseline PVI and change in SBP from baseline.

    Intraoperative (approximately 2 hours)

Secondary Outcomes (5)

  • Correlation between plethysmography variability index (PVI) change in response to passive leg raising (PLR) and change in SBP and pulse rate (PR) from baseline, and need for vasopressors

    Intraoperative (approximately 2 hours)

  • Correlation between intraoperative PVI change from baseline with change in SBP and PR from baseline, and need for vasopressors.

    Intraoperative (approximately 2 hours)

  • Correlation between baseline PVI and need for vasopressors.

    Intraoperative (approximately 2 hours)

  • Correlation between baseline PVI and change in SBP and PR from baseline.

    Intraoperative (approximately 2 hours)

  • Correlation between CO change in response to SLR with change in SBP and PR from baseline, and need for vasopressors

    Intraoperative (approximately 2 hours)
