Abstract

Background: The purpose of this study is to investigate the effects of cardiac displacement, regional ischemia and reperfusion to hemodynamics in four main settings of our technique on the beating heart coronary bypass. Methods: Thirty-one patients operated on the beating heart between October and December 2001 were included in this study. Heart rate (HR), mean systemic arterial pressure (MAP), central venous pressure (CVP), mean pulmonary arterial pressure (MPAP), pulmonary capillary wedge pressure (PCWP), cardiac output (CO) were measured during position, ischemia, reperfusion and at the end of the operation in anterior, lateral, posterior and inferior settings and compared to baseline values. Results: There were statistically significant reductions in MAP (except anterior position) and CO measurements compared to baseline in all position and ischemic settings. The CVP, MPAP, PCWP, HR (except lateral ischemia, posterior position and ischemia) increased according to the baseline in all position and ischemic settings. Variations were more significant during the manipulation of the posterior territories. All these hemodynamic changes returned to baseline with reperfusion (except HR in interior), though HR, CVP, MPAP, PCWP remained increased in the anterior setting. Heart rate was the single variable that remained high, all hemodynamic parameters returned to baseline at the end of the operation. Conclusions: Hemodynamic changes occur in all settings during beating heart coronary bypass. But all of these changes are transient and well tolarated by the patients.

Özet

Amaç: Çalışan kalpte koroner bypass sırasında kardiyak yer değiştirmenin, bölgesel iskemi ve reperfüzyonun kendi yöntemimizdeki dört ana duruşta hemodinamiye olan etkilerini araştırmaktır. Materyal ve Metod: Ekim-Aralık 2001 tarihleri arasında kliniğimizde elektif şartlarda çalışan kalpte koroner bypass uygulanan 31 hasta çalışmaya dahil edildi. Anterior, lateral, posterior ve inferior duruşlarda pozisyon, iskemi, reperfüzyon ve ameliyat sonunda kalp hızı (HR), ortalama sistemik arteriyel basınç (MAP), santral venöz basınç (CVP), ortalama pulmoner arter basıncı (MPAP), pulmoner kapiller "wedge" basıncı (PCWP), kardiyak debi (CO) değerleri ölçülerek başlangıç ile karşılaştırıldı. Bulgular: En belirgin değişiklikler posterior duruşta görülmekle birlikte tüm duruşlarda pozisyon ve iskemide MAP (anterior pozisyon hariç) ve CO düşerken, HR (lateralde iskemi, posterior pozisyon ve iskemi hariç), CVP, MPAP, PCWP arttı. Anterior duruş hariç tüm duruşlarda bu değişiklikler başlangıç değerlerine reperfüzyonla geri dönerken (inferiorda HR hariç), anterior duruşta reperfüzyon aşamasında HR, CVP, MPAP, PCWP yükseklikleri devam etti. Ameliyatın başlangıcındaki değerler ile sonunda tüm greffier dolaşıma açıldıktan sonra yapılan ölçümler karşılaştırıldığında başlangıca dönmeyen tek değer HR'ti. Sonuç: Çalışan kalpte koroner bypass sırasında tüm duruşlarda pozisyon ve bölgesel iskemi uygulanmasıyla hemodinamik bozulmalar gözlenebilmektedir. Ancak bu değişikliklerin hepsi geri dönüşümlüdür ve klinik önemi yoktur.
