Özet

Purpose: The aim of this study was to investigate the reliability of preanesthetic ultrasound measurements of the internal jugular vein (IJV) in predicting hypotension after the induction of general anesthesia. Methods: A total of 40 patients who underwent elective surgery under general anesthesia were enrolled in this prospective study. Before the induction of anesthesia, sonographic measurements of the IJV were performed both in the supine and Trendelenburg positions. The blood pressure values were measured every minute after the induction. The patients were then classified into hypotension and non-hypotension groups. The association between the sonographic measurements and the postinduction hypotension were analyzed. Results: Twenty-four (60%) patients developed postinduction hypotension. In a univariate analysis, the max (P=0.007) and min (P=0.20) IJV diameters in the supine position, the max IJV diameter (P=0.027), and the collapsibility index (P=0.029) in the Trendelenburg position were significantly different between the groups. In a logistic regression analysis, the collapsibility index in the Trendelenburg position was found to be an independent predictor of postinduction hypotension. An ROC curve analysis showed that the collapsibility index in the Trendelenburg position had a sensitivity of 62% and a specificity of 62% to predict postinduction hypotension at a cut-off point less than 19.9%. Conclusion: The collapsibility index of IJV in the Trendelenburg position seems to be an alternative predictor of postinduction hypotension.
