Abstract:
Objective To evaluate the effect of hypophysin and oxytocin on QT interval of the patients undergoing myomectomy. Methods Forty ASAⅠ-Ⅱ female patients scheduled for laparoscopic operation were enrolled. All patients were randomized into hypophysin or oxytocin group, with 20 patients in each group. The blood pressure, heart rate and QT interval were recorded at following time points: before anesthesia (T_1), before injection of hypophysin or oxytocin (T_2), 2 min (T_3), 5 min (T_4), 10 min (T_5), 20 min (T_6), and 30 min (T_7) after injection of hypophysin or oxytocin. Results The QT interval at 2, 5 and 10 min post injection of hypophysin were significantly longer compared to oxytocin group (P<0.01). No significant changes of QT interval were detected in oxytocin group, though the trend of QT interval prolongation were recorded. Conclusions In hysteromyoma operation, injection of hypophysin could prolong the QT interval of patients.
