The Use of Remote Ischemic Preconditioning Applied in Child the Day Before Open Heart Surgery With Extracorporeal Circulation to Correct Congenital Heart Diseases (the Second Window Effect)
The Use of Remote Ischemic Preconditioning Applied in Child the Day Before Open Heart Surgery With Extracorporeal Circulation to Correct Congenital Heart Diseases (the Second Window Effect)
The study research is to analyse brief episodes of limb ischemia applied to children the day before open heart surgery as protection from myocardial injury induced by extracorporeal circulation.
Children undergoing repair of congenital heart defects were randomized to RIPC (remote ischemic preconditioning) or control treatment. RIPC was induced by four 5-minutes cycles of lower limb ischemia and reperfusion using a blood pressure cuff. Measurements of troponin I, brain natriuretic peptide, interleukines 8 and 10, real time PCR to NFKB and clinical parameters were obtained and compared postoperatively (4, 12, 24 and 48 hous after).
