Defining perfscore parameters by evaluations by body weight in patients who underwent open heart surgery for non-cyanotic congenital heart disease between 01st january 2013 – 01st march 2017

Today, even in children with very low body weight, the treatment of congenital heart diseases is possible with open heart surgery. Open heart surgery is the heart surgery technique using the heart-lung machine. In this technique, the entire circulation is controlled by perfusionist. Perfusionists are able to influence the success of operations with advancing technology largely positive. The quality of the perfusion determines the mortality and morbidity of the patient, as well as the factors such as the length of stay in the intensive care unit, the total length of stay and extubation time. The inadequate cardiopulmonary bypass can produce results that can directly affect all other organs, especially the heart and lungs. The assessment of the performance of perfusion techniques in the world and in our country has not been standardized. While some studies have been reported in the literature without evaluating the performance of CPB in adult patients with PERFSCORE, evaluation with PERFSCORE has not yet been performed in patients operated on for congenital heart disease according to our current knowledge. In this study; performance score (PERFSCORE), which is a simple and reliable method, to evaluate the results of CPB used in children who were operated for non-syanotic heart disease. For PERFSCORE; we have identified twelve parameters. These include: perfusion time (min), aortic cross-clamp time (min), pH, pCO2, pO2, hematocrit (%), sodium (mmol / L), potassium (mmol / L), activated clotting time, lactate (mmol / L), creatinine (mg / dL), blood usage (number of units). These twelve parameters provide performance measurements. In our study; Between January 2013 and March 2017; (3288-GOA protocol no.) Patients who were operated for non-cyanotic congenital heart disease in our clinic with approval of hospital ethics committee (2017/29-05) were retrospectively screened and per-operative and postoperative early period data were used as 1-10 kg and 11-35 kg patient groups. In elective conditions, 60 pediatric open heart surgery patients were retrospectively analyzed. There was a statistically significant difference between groups in terms of perfusion scoring, RACHS-1, Down Syndrome, pulmonary hypertension, perfusion duration score, aortic cross-clamp score and death ratios (p <0,05). There was a statistically significant difference between the groups in terms of pH, Lactate, ACT, blood creatinine, urea and peritoneal dialysis (p <0,05). According to the weights of the cases, it was found that length, RACHS- 1, PERFSCORE points, age (month), perfusion duration (min), aorta cross-clamp (min), minimum body heat, cardioplegia application (number), intubation time There was a statistically significant difference between the groups in terms of all variables (p <0,05). 30th min pH, 30th min. pC, preoperative p, 30th min. hematocrit values were statistically significant (p <0,05). Preoperative BE, preoperative, and 30th min HCO3, 90th min. and the mean lactate values were statistically significant (p <0.05). In our opinion, PERFSCORE is an effective method for evaluating CPB.
