Abstract

Background: Esmolol has been found to prevent myocardial ischemia during cardiac surgery. Furthermore, adding glutamate-aspartate to blood cardioplegia was reported as myocardio-protective. We aimed to compare the myocardial protective effect of esmolol and glutamate-aspartat in blood cardioplegia in elective open heart surgery.Material and Methods: Forty five adult patients, ASA grade 3 scheduled for open heart surgery were included. Patients were randomly allocated according to the agent given in bolus added to cardioplegia by an anaesthetist who was blinded to the study; Group E (esmolol), Group GA (glutamate-aspartate), Group C (control). Cardiac output (CO), cardiac index (CI), troponin T (TT) and creatinine kinase MB (CK) were recorded after induction (t1), at the end of surgery (t2) and at 24 h postoperatively (t3).Results: Need of inotropic agent was more in Group C than the others. While values of CO in group C decreased , after the surgery values of CO was higher in Group E (p< 0.05). Although there were no differences in CK among the groups in all times, after the surgery values of CK-t3 and TT-t3 increased in all patients. Values of TT-t2 were higher in Group C than other groups during the operation.Conclusion: In open heart surgery, glutamate-aspartate and esmolol given in bolus added to blood cardioplegia are an advantage in myocardial protection.

Özet

Amaç: Kardiyak cerrahi sırasında kullanılan esmololün miyokardı koruyucu etkisi gösterilmiştir. Bununla birlikte kan kardiyoplejisine glutamat-aspartat eklenmesinin miyokardiyal koruma üzerine etkisinden de söz edilmektedir. Biz bu çalışmada açık kalp cerrahisinde kan kardiyoplejisine eklenen esmolol ve glutamat-aspartatın miyokardı koruyucu etkisini karşılaştırmayı amaçladık.Gereç ve Yöntem: Açık kalp cerrahisi planlanan ASA III 45 hasta çalışmaya dahil edildi. Hastalar kardiyoplejiye eklenen ve bolus olarak verilen Esmolol (Grup E), Glutamat-aspartat (Grup GA), Salin (Grup C) olarak rasgele 3 gruba ayrıldı. İndüksiyon sonrası (t1), cerrahi sonrası (t2) ve cerrahiden sonra 24. saatte, kardiyak output (CO), kardiyak index (CI), troponin T (TT) ve kreatinin kinaz MB (CK) değerleri kaydedildi.Bulgular: Grup C'de inotropik ajan gereksinimi diğer gruplara göre daha çoktu. Grup C'deki CO değerleri düşerken, cerrahiden sonra Grup E'de CO değerleri yüksekti (p< 0.05). Gruplar arasında CK değerleri bakımından bütün zamanlarda fark görülmezken, cerrahi sonrası bütün hastalarda CK-t3 ve TT-t3 değerleri yükseldi. Cerrahi süresince TT-t2 değerleri Grup C'de diğer gruplardan anlamlı olarak yüksekti.Sonuç: Açık kalp cerrahisinde, kan kardiyoplejisine bolus olarak eklenen glutamat-aspartat ve esmolol miyokardiyal korumada avantaj sağlamaktadır.
