Summary

Post-induction hypotension (PIH) is very common with high incidence about 9-60%. There are multiple factors that may cause PIH, like pre-operative fasting, bowel preparation, vasodilatation due to anesthetics, and reduced stimulation during preparation before incision. Hypotension could cause tissue hypoperfusion, ischemia and higher risk for stroke or myocardial infarction, which result in higher risk for prolonged hospital stay or death. In general surgical patients, lower pre-induction SAP, older age (\>50 years old), and emergency surgery are independently associated with PIH. In this study, we would like to use a wireless continuous non-invasive sonography device to evaluate if the change of cardiac output during the perioperative period could predict PIH.

Ｗe would like to enroll 80 patients of ASA class I to III who undergo abdominal surgery. GIS-Heartio® will be used to estimate the cardiac parameters one day before the surgery (Day 0) and after the patient enter the operation room till wound incision. Passive leg raise test would be performed on day 0 and before induction. We will analyze the patient's demographic data and the cardiac parameters to see if continuous cardiac output monitor can predict the occurrence of PIH.
