AB - 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 evalu- ation just before induction could predict the occurrence of such hypotension. Methods Adult patients undergoing surgery under general anesthesia were enrolled after excluding patients with cardio- vascular disease or ASA-PS ≥ III. Ultrasonographic IJV images were recorded in both the supine and 10° Trendelenburg positions immediately before induction. Using these images, IJV area (IJV-A), diameter and change rate with posture were measured. Hypotension during induction was defined as mean BP < 60 mmHg or > 30% decrease from baseline. Results Hypotension during induction was observed in 37 of 82 patients. IJV-A in the Trendelenburg position was 2.02 ± 0.86 and 1.72 ± 0.68 in the hypotensive and non-hypotensive groups, respectively (P = 0.08). Logistic regression analysis per- formed using age, use of calcium antagonists, angiotensin converting enzyme inhibitors/angiotensin receptor blockers, baseline mean BP and IJV-A in the Trendelenburg position as variables showed that IJV-A in the Trendelenburg position was an independent predictor of
