Randomized Controlled Trial Comparative StudyQT interval and QT dispersion during the induction of anesthesia and tracheal intubation: a comparison of remifentanil and fentanyl.
The aim of this paper was to determine if there were any significant differences between the effects of fentanyl delivered as a bolus or remifentanil delivered as a continuous infusion on the QT interval and QT dispersion (QTD) during the induction of anesthesia and tracheal intubation. ⋯ Both remifentanil and fentanyl did not prolong the QT interval. QTD decreased after the induction of anesthesia and did not increase after tracheal intubation in patients receiving c.i. remifentanil in comparison with fentanyl. Overall, remifentanil infusion may be the opioid-based treatment regimen of choice in patients at risk of dysrhythmias.
