Objective To explore the prophylaxis and treatment of hypoxic spells on patients with TOF.Methods Retrospectively analysed and compared the case history of the inpatients with TOP in our hospital,to analyse the epilepticus cause of hypoxic spells and study the hypoxia mechanism and summarize the prevention and control measures.Results 4(17%)cases of TOF died after hypoxic spells,the epilepticus cause of hypoxic spells included suckling,early getting up,crying,standing abruptly after stool,scorching climate,infection fever and anemia,the hypoxia mechanism was likely to the increase of infundibulum cardiac muscle contraction,the systemic circulation resistance drop suddenly,hypezventilation,high-viscosity syndrome.Conclusion To control the epilepticus cause and perform operative treatment early can reduce the hypoxic spells.The prevention and control measures were strengthening the live nurse,disconnected oxygen inhalation,oral beta-blocker therapy and venons injection 5% sodium bicarbonate.Early operative treatment was the best redical treatment.

Objective To investigate the etiology clinical diagnosis and treatment of pediatric neurogenic pulmonary edema(NPE).Methods The clinical data of 18 hospitalized children with NPE were retrospectively analyzed.Results 18 cases of NPE children with traumatic brain injury 2 cases( 11.1％ ),cervical spinal cord injury 1 case(5.5％ ) and,subarachnoid hemorrhage 2 cases( 11.1％ ),and epilepticus states 2 cases( 11.1％ ),non-HFMD caused encephalitis 3 cases( 16.6％ ),NPE caused hand,foot and mouth disease 8 cases(45.6％ ),survival 6 cases (33.3％) and 12 patients died (66.7％)in 18 hospitalized children with NPE.Conclusion The common cause of pediatric NPE was central nervous system infections and poor prognosis,early diagnosis and early treatment could improve the efficacy and prognosis.
