Ringer acetate versus ringer lactate cardioplegia: a comparative study in mitral valve surgery

ABSTRACT

Background: ringer lactate has long been used in many surgical procedures as one of the isotonic solutions. However, with the development of Ringer acetate, it becomes the crystalloidof cholce owing to its main metabolism in muscles unlike lactate which is mainly in liver, also it corrects acidosis more rapidly than lactate and it needs less O[2] and produces less CO[2]. Ringer acetate has also a great utility during cardiovascular surgery with cardiopulmonary bypass. We compared efficacy and safety of Ringer acetate versus lactate in preparing cardioplegic solution during mitral valve surgery
