Abstract：Objective To investigate the trend and clinical application value of abdominal oxygen saturation(ArSO2)in infants and young children undergoing corrective surgery for congenital heart disease.Methods A total of 53 children weighing 4.0-9.8 kg and aged 2.5-11 months,American Society of Anesthesiologists(ASA)classification Ⅱ-Ⅲ who underwent ventricular septal defect repair under cardiopulmonary bypass(CPB)at the Fuwai Central China Cardiovascular Hospital from September to December 2023 were randomly selected.The probe of the near-infrared spectroscopy(NIRS)was fixed directly below the navel of the child,and the ArSO2 was continuously monitored during the operation.The changes in parameters such as ArSO2,nasopharyngeal temperature,and MAP after entry(T,),immediately after CPB(T2),5 minutes after aortic occlusion(T3),5 minutes after aortic opening(T4),5 minutes after CPB(T5),and 5 minutes before surgery(T6)were record.Relevant information such as intraoperative aortic occlusion time,CPB time,and surgical time,ICU stay time,mechanical ventilation time,and hospitalization time were record.According to the time of first postoperative feeding,the children were divided into gastrointestinal dysfunction group and without gastrointestinal dysfunction group.Results Out of 53 infants and young children,22 cases(41.5％)experienced delayed gastrointestinal function.At T1,there was no statistically difference in ArSO2 between the two groups of children(P＞0.05).At T2-6,compared with the group without gastrointestinal functional delay,the ArSO2 value of children with gastrointestinal functional delay was lower(P＜0.05).There was no statistically difference in nasopharyngeal temperature and mean arterial pressure(MAP)between the two groups of children fromT1-6(P＞0.05).Compared with the group without gastrointestinal functional delay,the age and weight of children in the gastrointestinal functional delay group were younger and lower(P＜0.05).Compared with the group without gastrointestinal functional delay,the group with gastrointestinal functional delay showed an increase in aortic occlusion time,CPB time,and surgery time,as well as longer postoperative stay in the intensive care unit,mechanical ventilation time,and hospitalization time(P＜0.05).Pearson correlation analysis showed that,ArSO2 was negatively correlated with nasopharyngeal temperature(r=-0.321,P=0.019)and positively correlated with MAP(r=0.421,P＜0.001).Conclusion Near infrared spectroscopy imaging,as a new non-invasive monitoring method for intestinal function,has certain clinical guidance value in the perioperative period of congenital heart disease in infants and young children.
