Résumé
Objective To investigate the metabolism change of intestinal flora due to chronic hypoxia in infants. Methods Ten infants with tetralogy of fallot were considered as the chronic hypoxia group,10 healthy infants were regarded as the control group. The urine concen-tration of hippurate in the morning with fasting was detected by 1 H nuclear magnetic resonance. Results The concentration of hippurate was decreased in hypoxia group compared with the control group,(47. 15 ± 32. 88) mg/L vs (346. 698 ± 13. 555) mg/L,with significant differ-ence,P=0. 002. Conclusion Chronic hypoxia alters metabolism of intestinal flora in infants.
Résumé
Objective To summarize cardiopulmonary bypass management in open heart surgery of children with congenital heart disease. Methods The clinical data of 80 children with age less than 4 years old underwent open heart surgery under cardiopulmonary bypass from January,2005 to January,2009 were retrospectively analyzed. Results The operations of all 80 cases were basically smoothly and no severe complications associated with extracorporeal circulation occurred. After cross-clamping releasing,automatically re-beating occurred in 75 cases,and 5 re-beat after electric shock. There was no postoperative death. Conclusions Open heart surgery under cardiopulmonary bypass is safe and efficacy in children with congenital heart disease.
