The Effects of Different Anesthetic Techniques on QT, Corrected QT (QTc), and P Wave Dispersions in Cesarean Section

2017-05-02 11:08:21 | BioPortfolio


This study evaluates the effects of different anesthetic techniques on QT, QTc, and Pwd in cesarean section. Half of participants received general anesthesia, while the other half received spinal anesthesia Electrocardiography (ECG) recordings were performed at preoperative, 5, 15, 30 min after initiation anesthesia and 30 min post-operatively. Hemodynamic state were also recorded at the same time intervals. QT, corrected QT (QTc), QT dispersion (QTd), QTc dispersion (QTcd), P-wave dispersion (Pwd), corrected JT interval, T wave (Tp-e), transmular dispersion of repolarization durations were measured from ECG records at predetermined time intervals of spinal or general anesthesia.


The anesthetic drugs used according general or regional anesthesia techniques can display proarrhythmic and antiarrhythmic effects by inducing cardiac electrical signals with different pathways.In addition, comorbid disease, hormonal changes, surgery procedures, and drug therapy can all cause arrhythmia in the intraoperative period. Likewise, pregnancy causes many changes hormonal and physiological in women. Hemodynamic and hormonal changes during pregnancy can cause effects proarrhythmogenic that cause premature atrial and ventricular beats to develop.

Medical and Biotech [MESH] Definitions

Abnormal increase in RESPIRATORY RATE in the newborn. It is self-limiting and attributed to the delayed fetal lung fluid clearance often in CAESAREAN SECTION delivery.

A widely used local anesthetic agent.

A local anesthetic with rapid onset and long action, similar to BUPIVACAINE.

A local anesthetic and cardiac depressant used as an antiarrhythmia agent. Its actions are more intense and its effects more prolonged than those of procaine but its duration of action is shorter than that of bupivacaine or prilocaine.

A local anesthetic that is chemically related to BUPIVACAINE but pharmacologically related to LIDOCAINE. It is indicated for infiltration, nerve block, and epidural anesthesia. Mepivacaine is effective topically only in large doses and therefore should not be used by this route. (From AMA Drug Evaluations, 1994, p168)
