Ultrasonography evaluation of the inferior vena cava collapsibility index and the superior vena cava distensibility index for predicting hypotension during general anesthesia in atrial fibrillation patients: a prospective observational study.

ABSTRACT:

Background

Atrial fibrillation (AF) is a prevalent arrhythmia, the ineffective contraction of the atria leads to a decrease in effective cardiac output. AF patients are prone to hypotension during anesthesia, especially in the early stages of general anesthesia. We explored whether the inferior vena cava collapsibility index (IVCCI) or the superior vena cava distensibility index (SVCDI) could predict the occurrence of post-induction hypotension (PIH) and early intraoperative hypotension (eIOH) in AF patients.

Methods

A total of 77 AF patients undergoing left atrial appendage occlusion under general anesthesia were included in this study. The inferior vena cava was measured before induction and the superior vena cava after induction. The main outcome was the ultrasound measur
