Adding Lidocaine to Custodiol Mixture

The Bretschneider solution, also known as Custodiol, has been widely used in open-heart surgery requiring cardiopulmonary bypass (CPB) since its introduction in 1970. Custodiol is widely favored by cardiac surgeons, being administered as a single dose, and is supposed to offer myocardial protection for up to three hours, permitting an uninterrupted surgical time, especially for intricate procedures The literature continues to debate the superiority of custodial and other cardioplegic solutions, such as the Del Nido and St. Thomas solutions, regarding both short-term and long-term outcomes. Clinical trials and daily practice showed that the use of custodial cardioplegic solution is associated with increased incidences of ventricular arrhythmias, and subsequently, the use of a defibrillator after Aortic Cross Clamp (ACC) removal at the end of CPB when compared to other types of cardioplegia solutions .One of the reasons for this difference mentioned in the literature is the lidocaine contained in other types of cardioplegic solutions. Lidocaine acts as a membrane stabilizer by blocking rapid sodium channels in the heart, thus preventing arrhythmias, in addition to its ability to inhibit calcium influx, which is the primary cause of ischemic-reperfusion injury. Based on these data, the investigators hypothesize that the increased incidence of Ventricular arrhythmias with the use of Custodiol compared to other solutions, such as St Thomas and Del Nido, may be attributed to the a…
