Abstract

Objective: To determine whether glutamat and aspartat enriched cold crystalloid cardioplegia which was given in antegrade way has any effect on the myocardial protection during cardiopulmonary bypass. Material and Methods: Thirty-four patients who were electively undergone open heart surgery at Osmangazi University Faculty of Medicine, thoracic and cardiovascular surgery department, between March 2001 and May 2001 were included in this study. The patients were divided in two groups, each consisting of 17 patients. In group 1 coronary artery bypass surgery (CABG) was performed in 11 patients, mitral valve replacement (MVR) in 3 patients, aortic valve replacement (AVR) in 1 patient and AVR and MVR in 2 patients. While in group 2 CABG was performed in 13 patients and MVR was done in 4 patients. Group 1 patients received antegrade glutamat and aspartat (15 mmol/L) enriched cold crystalloid cardioplegia and group 2 patients were given cold crystalloid cardioplegia by antegrade route. Age, gender, diabetes mellitus, hypertension, preoperative myocardial infarction, smoking, ejection fraction, aortic cross-clamp time, need to defibrillation, inotropic support, and intraaortic balloon pump were recorded. The levels of cardiac troponin I (cTI) and creatine kinase myocardial band fraction (CK-MB) were measured in arterial blood samples at five different times. Statistical analysis was performed using Student’s t-test and Chi-square test. Results: There were no statistically significant differences in cTI and CK-MB values in blood samples taken at 5 different times pre and postoperatively between group 1 and group 2. Conclusion: It is concluded that glutamat and aspartat enriched cold crystalloid cardioplegia does not have any effect on myocardial protection.

Özet

Amaç: Kardiyopulmoner baypas (KPB) sırasında antegrad yoldan verilen glutamat ve aspartat ile zenginleştirilmiş soğuk kristalloid kardiyoplejinin, miyokardiyal koruma üzerine etkisinin olup olmadığının bulunması amaçlandı. Yöntem: Osmangazi Üniversitesi Tıp Fakültesi Göğüs Kalp Damar Cerrahisi Anabilim Dalında, Mart 2001 ile Mayıs 2001 tarihleri arasında elektif açık kalp cerrahisi yapılan 34 hasta çalışmaya dahil edildi. Hastalar 17’şer kişilik iki gruba ayrıldı. Grup 1’de 11 hastaya koroner baypas (KABG), 3’üne mitral kapak replasmanı (MVR), 1’ine aort kapak replasmanı (AVR) ve 2’sine AVR+MVR operasyonu yapıldı. Grup 2’de 13 hastaya KABG, 4’üne MVR operasyonu yapıldı. Grup 1’de glutamat ve aspartat ile zenginleştirilmiş soğuk kristalloid kardiyopleji (15 mmol/L), grup 2’de ise soğuk kristalloid kardiyopleji, antegrad yoldan verildi. Yaş, cins, diyabetes mellitus, hipertansiyon, preoperatif miyokard infarktüsü, sigara, ejeksiyon fraksiyonu, aort kros-klemp süresi, defibrilasyon yapılan, inotropik destek verilen ya da intraaortik balon pompası desteği gereken hastalar kaydedildi. Beş farklı zamanda arteryel kan örnekleri alınarak, kardiyak troponin I (cTI) ve kreatin kinaz miyokard bandı (CK-MB) düzeyleri ölçüldü. İki grup arasında farklılık olup olmadığı istatistiksel olarak Student’s t testiyle değerlendirildi. Bulgular: Grup 1 ve grup 2’de preoperatif ve postoperatif alınan kan örneklerinde çalışılan cTI ve CK-MB değerleri arasında istatistiksel olarak anlamlı bir farklılık bulunmadı.Sonuç: Glutamat ve aspartat ile zenginleştirilmiş soğuk kristalloid kardiyoplejinin miyokardiyal koruma üzerine herhangi bir etkisinin olmadığı sonucuna varıldı.
