Prolonged Corrected QT Interval Is Associated with Lower Incidence of Maternal Hypotension During Spinal Anesthesia in Cesarean Delivery: A Prospective Observational Study.

ABSTRACT: Background and Objectives: Spinal anesthesia is a common anesthetic method for cesarean delivery. However, it is associated with spinal hypotension, which can negatively impact both the mother and the fetus. We hypothesized that parturients with preoperatively prolonged corrected QT interval (QTc) would have a lower incidence of developing spinal hypotension. Materials and Methods: This prospective observational study analyzed eighty-five parturients undergoing cesarean delivery. The participants were divided into two groups based on their baseline QTc, which was measured automatically using a patient monitor in the operating room rather than using a standardized 12-lead electrocardiogram: <440 ms (n = 42) or ≥440 ms (n = 43).
