Brief Summary

Intraoperative hypotension (IOH) is defined as a mean arterial pressure (MAP) of \< 65mmHg during surgery. Patients undergoing major gastrointestinal (GI) surgery, such as esophagectomy with reconstruction, are at a high-risk of IOH because such surgeries typically require more than 3h to complete and require blood transfusion or inotrope administration. Critically, these surgeries involve organ removal or substitute connection, which require wound or flap anastomosis. IOH is believed to be associated with postoperative anastomosis necrosis. It increases the risk of postoperative intrathoracic or abdominal infection, resulting in septic shock, postoperative major organ dysfunction and mortality. The data of TWA-MAP\< 65mmHg in the HPI guidance group will be significantly lower than that in the group without HPI guidance.

Conditions

Outcome Measures

Primary Outcomes (1)

  • time-weighted average mean arterial pressure less than 65 mmHg

    .A higher data of time-weighted average mean arterial pressure less than 65 mmHg indicates severe and longer intraoperative hypotension

    during the operation

Study Arms (2)

patients with hypotension prediction index guided

ACTIVE COMPARATOR

Patients receiving hypotension prediction index guided. In this group, they will be alerted when the index exceeded 85 (range 0 to 100) indicating the later occurrence of MAP\< 65mmHg for at least minutes and a treatment protocol based on advanced hemodynamic parameters recommended vasopressor or inotrope, fluid administration, or observation.

Device: hypotension prediction index guided

patients without hypotension prediction index gudied

OTHER

Patients will receive usual care during the operation without hypotension prediction index alerted.

Device: without hypotesion prediction index guided

Interventions

patients receiving hypotension prediction index monitoring and let the anesthesiologist' alerted the coming intraoperatiobe hypotension

patients with hypotension prediction index guided

patients receiving usual care without hypotension prediction index monitoring but with usual arterial line care

patients without hypotension prediction index gudied
