Abstract

Background: Cardioplegia is used for protection of myocardium during cardiac operations. Del Nido (DN) and Custodiol cardioplegia solutions are used for prolonged protection of the myocardium during cardiopulmonary bypass (CPB). Custodiol cardioplegia (CC) solution is gaining popularity for myocardial protection during cardiopulmonary bypass. Objectives: This study aimed to compare the effects of Custodiol with another cardioplegia solution, Del Nido, on myocardial protection during cardiopulmonary bypass. Methods: In a randomized controlled clinical trial, forty patients were randomly allocated to DN and Custodiol (CC) groups. Patients in both groups received a normal anesthesia protocol. For cardioplegia, in the DN group, the DN solution was administered every 90 minutes by the antegrade route. In the Custodiol group, the Custodiol solution was administered in the same way at the beginning of the cardioplegia. Demographic information, blood chemistry parameters and other related perioperative and postoperative clinical indices were recorded. Results: Frequency of female patients was 14/21 (66.66%) in the DN and 12/19 (63.15%) in the CC group (P = 0.816), age was 57.14 ± 12.48 years in the DN and 59.47 ± 11.96 years in the CC group (P = 0.551), weight was 70.95 ± 9.56 kilograms in the DN and 69.63 ± 7.64 kilograms in the CC group (P = 0.635), CPB time was103.19 ± 23.43 minutes in the DN versus 97.36 ± 16.7 minutes in the CC group (P = 0.376), and cross-clamp time was 73.76 ± 19.66 minutes in the DN and 83.95 ± 16.14 minutes in the CC group (P = 0.083). Blood chemistry and blood gas analysis revealed a similar trend between the two groups in these parameters (P > 0.05) except for higher sodium levels after cardioplegia (P = 0.016) and end of CPB (P = 0.002), potassium levels after cardioplegia (P = 0.029), and bicarbonate anions at the end of bypass (P = 0.03) in the custodiol group. Conclusions: In conclusion, CC and DN offer effective myocardial protection during cardiopulmonary bypass. It is recommended to restrict the use of CC in patients susceptible to electrolyte disturbances. © 2018, Author(s).
