Objective:To investigate the correlation between intraoperative complications during interventional therapy in children with congenital heart diseases and anesthesia management safety and to put forward corresponding preventive measures. Methods:A retro-spective analysis was made on type,incidence,cause and treatment of adverse events after undergoing different anesthesia treatments (intravenous anesthesia,laryngeal mask combined with intravenous inhalation anesthesia and tracheal intubation) in 1 792 cases of interventional therapy. Results:Incidence of adverse event related with anesthesia was 3.63%(65/1 792). After timely treatment,all recovered well. Incidence of adverse event related with operation was 2.40%(43/1 792),including 4 death cases died with mortality of 0.22%(4/1792). The intravenous anesthesia group had the highest incidence of adverse events(12.6%,P=0.000). Conclusion:Choosing appropriate anesthesia methods based on patients’ different physical condition can strengthen management of high risk fac-tors and formulate appropriate urgent treatment plan. Effective peri-operative monitoring and effective cooperation can reduce the in-cidence of serious complications in children’s congenital heart disease intervention.
