Brief Summary

The incidence of intraoperative hypotension was 91%. The increasing incidence of intraoperative hypotension would increase the risk of postoperative complications, such as postoperative arrythmia, stroke or acute kidney injury. Major gastrointestinal surgery is a major surgery. Older patients usually have many comorbidity, such as hypertension or cardiovascular disease. Prevention intraoperative hypotension is an important issue. Hypotension prediction index (HPI) could give the clinician pre-alarm of hypotension (mean arterial pressure (MAP)\<65mmHg). In this study, we aimed to investigate whether HPI could prevent the intraoperative hypotension happened in patients receive elective major gastrointestinal surgery with older than 65 years old.

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

    preoperative and postoperative 30 days

Study Arms (2)

hypotension prediction index guided

EXPERIMENTAL

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

without hypotesion prediction index guided

SHAM COMPARATOR

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

Other: without hypotesion prediction index guided

Interventions

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

hypotension prediction index guided

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

without hypotesion prediction index guided
