Feasibility of myocardial pH-monitoring during heart surgery under conditions of cardioplegic ischemia.
The first results of the use of pH-monitoring of the myocardium with a Khuri monitor (Terumo Cardiovascular Systems Corporation) are presented. Before aorta clamping, the pH changes depended on the initial degree of damage to the examined myocardial segment. The cardioplegia protocol was urgently modified due to pH-monitoring, which helped to normalize pH and to prevent severe postoperative complications. The thermometric and pH-metric data were compared with the results of clinical and morphological studies. pH-monitoring made it possible to control myocardial vitality during the surgical intervention.
