Pre-anesthetic ultrasonographic assessment of the internal jugular vein for prediction of hypotension during the induction of general anesthesia

Purpose Severe hypotension caused by anesthetic administration for anesthesia induction, which might cause ischemic stroke, myocardial injury, acute kidney injury and postoperative mortality, should be prevented. Anesthesiologists are familiar with ultrasound examination of the internal jugular vein (IJV). This study aimed to clarify whether ultrasonographic IJV evaluation just before induction could predict the occurrence of such hypotension.
