the Severity and Duration of Intraoperative Hypotension Clinical Trial
Official title:
Applying Hypotension Prediction Index Guidance for Prevention of Intraoperative Hypotension in Older Patients Undergoing Major Gastrointestinal Surgery: A Randomized Trial
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.
Background: 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). Objectives: to investigate whether HPI could prevent the intraoperative hypotension happened. Patients and methods: The patients receive elective major gastrointestinal surgery with older than 65 years old. These patients have divided into two groups, including with/without HPI guided. The intraoperative hypotension incidence has been measured. Expected result: The HPI would significantly decrease the intraoperative hypotension incidence. ;
