Randomized Controlled TrialDifferential effects of propofol and sevoflurane on QT interval during anesthetic induction.
There have been conflicting reports on whether propofol prolongs, shortens, or does not change QT interval. The aim of this study was to determine the effect of target-controlled infusion (TCI) of propofol on heart rate-corrected QT (QTc) interval during anesthetic induction. We examined 50 patients undergoing lumbar spine surgery. ⋯ HR decreased after anesthetic induction and recovered after tracheal intubation in group P, whereas it did changed in group S throughout the study period. QTc interval was shortened at T3 and T4 in group P, but prolonged at T3, T4, and T5 in group S, as compared with T1. Propofol TCI shortens QTc interval, whereas sevoflurane prolongs QTc interval during anesthetic induction.
