BNP, TnI and Lactic Acid variations in Warm Blood Cardioplegia vs Cold Crystalloid Cardioplegia in Coronary Artery Bypass Grafting (CABG)

Introduction: Myocardial protection is one of the key points during cardiac surgery. Inadequate myocardial protection in cross-clamping period is an issue of concern in cardiac surgery.  Cardioplegic solutions improve the tolerance of ischemia and reperfusion by preserving myocardial energy reserves, preventing osmotic, electrolyte imbalances and acidosis. Warm blood cardioplegia (WBC) has had a profound impact, especially in coronary artery bypass surgery and there have been many studies that compared it with Cold crystalloid cardioplegia (CCC). A good myocardial protection will be reflected especially on patients outcome, on postoperative ICU strategy, morbidity and mortality as well. Brain Natriuretic Peptide (BNP), Troponin I (TnI) and Lactic Acid LA) are very significant biomarkers that reflects an adequate myocardial and organ perfusion/protection. The purpose of this study is to determine if warm blood cardioplegia offers any advantages in comparison with CCC in Coronary Artery Bypass Grafting (CABG) based primary on variations of BNP, TnI and Lactic Acid. Patients and method: 60 patients with coronary artery disease (CAD) that will have Coronary Artery Bypass Surgery (CABG), were retrospectively randomized in two groups of 30 patients with different techniques of myocardial protection: group A had CCC, and group B had warm blood cardioplegia (WBC), according to Calafiore [1] protocols). Intraoperative and postoperative variables were used to assess primary outcomes. Results: This study found benefits of warm blood cardioplegia in clinical outcome after CABG Keywords:Myocardial protection, Cardiac surgery, Cardiopulmonary Bypass, Calafiore, Cardioplegia, Coronary Artery Bypass Grafting (CABG), Brain Natriuretic Peptide (BNP), Troponin I (TnI) and Lactic Acid LA) DOI: 10.7176/ALST/95-02 Publication date: November 30th 202

Acute Traumatic Pericardial Tamponade.

Acute traumatic pericardial tamponade is a serious and rapidly fatal injury. As penetrating chest wounds are becoming more cammon, early diagnosis of tamponade is important so that life savingtreatement can be started. The classical features of tamponade may a be modified by hypovolemia and the presence of associated injuries. Acute tamponade may also be precipitated by rapid administration of large volumes of fluid. Echocardiography is limited by availability and operator dependence. Pericardiocentesis, while sometimes life saving is dangereous and limited value. A higher deagree of clinical suspincion in patients with chest injuries, together with close monitoring and revaluation, particulary during volume remplancement is essential. This paper describes one patient presented to the emergency department of University Hospital Center “Mother Theresa “ and it discusses the epidemiology and management principles of acute tamponade
