Purpose of the study. Comparative assessment of the incidence of nosocomial purulent-septic infections (PSI) in children after open and closed heart surgery for congenital defects.Materials and methods. 503 medical records of children after cardiac surgery were studied. GSI was identified according to epidemiological standard case definitions.Results. It turned out that the incidence rate of PSI in children after open heart surgery is an order of magnitude higher than after minimally invasive endovascular interventions. Hospital-acquired pneumonia most often occurs in children after operations.Conclusion. The increased incidence of PSI after open heart surgery, as compared to endovascular surgery, is due to a longer surgical intervention and the subsequent longer stay of patients in the intensive care unit, where such an epidemiologically significant procedure as artificial lung ventilation is performed.

BACKGROUND: The widespread increase in the number and types of cardiac surgery necessitate the study of frequency and risk factors of postoperative purulent-septic infections (PSIs). AIM: to provide a comparative assessment of the PSI frequency and risk factors in adult patients after various types of cardiac surgery. MATERIALS AND METHODS: Based on the cardiac surgery hospital materials, medical records of 4.815 patients over 18 years of age, who underwent open (n = 1.540) and closed (n = 3.275) heart surgeries within 1 year, were analyzed. The typical and prenosological forms of PSIs were taken into account in accordance with the epidemiological standard of case definition. RESULTS: The incidence rates for typical and prenosological PSI forms amounted to 39.6 and 72.7 per 1000 surgeries after open heart surgery, respectively, and 3.1 and 3.9 after minimally invasive endovascular surgical interventions, respectively. The main clinical forms of PSI after open and closed heart surgeries were surgical site infections, nosocomial pneumonia, urinary tract infection, and bloodstream infection. In an open heart surgery, the maximum incidence rates for typical and prenosological forms of PSIs were recorded after surgeries on the aorta and less often after heart valve replacement or coronary artery bypass grafting. The increased incidence rate after aortic surgery was mainly due to urinary tract infection and nosocomial pneumonia. In the case of closed heart surgery, no statistically significant differences were detected between the incidence rates of PSIs after coronary artery stenting, cardiac arrhythmia and carotid artery stenosis surgery, and other interventions. The duration of both the surgery itself and the subsequent patient stay in the intensive care unit was found to be important as risk factors for PSIs after cardiac surgery. CONCLUSION: The incidence rate of PSIs after open heart surgery is significantly higher than after closed heart surgery, which is mostly associated with the duration of surgical intervention and the subsequent patient stay in the intensive care unit.

Anyone anxious to know more about developments in the rapidly-expanding field of surgical repair of congenital defects of the heart by open-heart techniques will find this paper instructive. The various types of apparatus which have been used to maintain the circulation and oxygenation of blood outside the body, leaving the heart free for surgical repair, are described. The physiologic changes during total-body perfusion and the means taken to insure homeostasis during the procedure are discussed. The author gives a brief description of his experience in the repair of congenital defects of the heart with the various techniques. A considerable body of interesting information is provided in a succinct and clear fashion for the general reader.

Between October 1984 and January 1993, seven children of Jehovah's Witnesses underwent corrective open-heart surgery for congenital defects, on cardiopulmonary bypass (CPB). Age at surgery ranged from three months to 6.5 years, and weight ranged from 4.2 kg to 23.2 kg, with two children weighing less than 10 kg. The principal cardiac anomalies were tetralogy of Fallot (two), double outlet right ventricle (one), subaortic stenosis (one), transposition of the great arteries and ventricular septal defect (one), atrial septal defect and congenital heart block (one), and congenital mitral regurgitation (one). Hypothermic CPB was used in all seven operations with crystalloid priming of the extracorporeal circuit. CPB was based on our standard perfusion protocols. All surgical procedures were done without the use of blood or blood products. The mean preoperative haematocrit (Hct) was 40.9% (range 31.0-47.8%). The mean lowest intraoperative Hct was 17.3% (range 15.0-24.3%), whereas the immediate post-CPB Hct was 19.6% (range 15.3-24.0%). The Hct progressively increased to 29.2% (range 21.0-34.2%) on the first postoperative day, and 32.3% (range 24.2-38.3%) at the time of discharge. There was no hospital mortality, and the mean hospital stay was 10 days (8-13 days). We report the safe repair of complex open-heart surgery in children, without blood transfusion, even in small infants. The successful management of these patients requires meticulous attention to surgical and perfusion technique, and sound postoperative management.

The Mean

SummaryA prospective study in 13 patients undergoing open-heart surgery with extracorporeal circulation revealed a marked decrease of the mean one-stage prothrombin time activity from 88% to 54% (p <0.005) but lesser decreases of factors I, II, V, VII and X. This apparent discrepancy was due to the appearance of an inhibitor of the extrinsic coagulation system, termed PEC (Protein after Extracorporeal Circulation). The mean plasma PEC level rose from 0.05 U/ml pre-surgery to 0.65 U/ml post-surgery (p <0.0005), and was accompanied by the appearance of additional proteins as evidenced by disc polyacrylamide gel electrophoresis of plasma fractions (p <0.0005). The observed increases of PEC, appearance of abnormal protein bands and concomitant increases of LDH and SGOT suggest that the release of an inhibitor of the coagulation system (similar or identical to PIVKA) may be due to hypoxic liver damage during extracorporeal circulation.
