Clinical Trial: Preoperative Caval-Aortic Index and Pleth Variability Index for Predicting Post-Induction Hypotension in Colorectal Surgery

U.S., Oct. 16 -- ClinicalTrials.gov registry received information related to the study (NCT07876362) titled 'Preoperative Caval-Aortic Index and Pleth Variability Index for Predicting Post-Induction Hypotension in Colorectal Surgery' on Oct. 09.

Brief Summary: This prospective observational study evaluated whether the preoperative caval-aortic index and pleth variability index can predict post-induction hypotension in adult patients undergoing elective colorectal surgery under general anesthesia. Preoperative caval-aortic index and pleth variability index values were recorded before anesthesia induction. Blood pressure was measured before induction and at 1, 3, 5, 7, and 10 minutes after induction. Post-induction hypotension was defined as...
