Abstract:
Objective To observe the effect of CO2 pneumoperitoneum combined with position changes on the stability of cardiac electrophysiology in gynecological laparoscopy. Methods The gynecological laparoscopy was performed for 30 patients to undergo elective gynecological laparoscopy under general anesthesia ,with the pneumoperitoneum pressure of 12 mmHg and the Trendelenburg positionat 15° . The observations and analyses were done over the basic monitoring index and the QT interval (QT),T peak tend interval (Tp-e),heart rate corrected QT interval(QTc),QT dispersion(QTd),Tp-e/QT before anesthesia(T0),after anesthesia(T1),1 min after pneumoperitoneum (T2),30 min after pneumoperitoneum and head-down tilt (T3),30 min after deflation and supine position(T4). Results Compared with the time point of T0,QTd increased significantly at T1(P<0.05) and so it was with QT,QTc,QTd,Tp-e,Tp-e/QT at T2,T3,and T4(P<0.05). Compared with the time point of T2,QTc,QTd,Tp-e,Tp-e/QT significantly increased at T3(P < 0.05). Conclusions CO2 pneumoperitoneum combined with Trendelenburg position can prolong ventricular repolarization duration and destroy the stability of cardiac electrophysiology so it may increase the incidence of cardiovascular events.
