ABSTRACT
Pregnancy has increased susceptibility to H1N1 influenza virus infection. Maternal influenza infection is associated with increased risk of morbidity and mortality. A case of influenza A (H1N1) during late pregnancy (pregnancy 1, birth 0, pregnancy 30+2 weeks) was admitted to the Second Affiliated Hospital of Kunming Medical University on December 16th, 2018. The patient was set on mechanical ventilation with a FiO2 of 1.0, a positive end-expiratory pressure (PEEP) of 15 cmH2O (1 cmH2O = 0.098 kPa), and a tidal volume of 4-6 mL/kg (ideal body weight). However the pulse oxygen saturation (SpO2) could only be maintained at about 0.85. The disease was controlled by the treatments of anti-infection, mechanical ventilation, immune therapy, nutritional support, preventive anticoagulant treatment by heparin sodium, adequate negative fluid balance, and other organ support therapy. This article introduced the treatment process of the patient in detail, and provided experience for clinical treatment.

ABSTRACT
Objective To analyze the clinical feature of pediatric severe influenza A(H1N1)cases.Methods To summarize the clinical manifestation,diagnostic and therapeutic process of eight pediatric severe influenza A(H1N1)cases.Results All eight cases couldn't provide contact history.Four cases had fundamental diseases,which were nephrotic syndrome,congenital hypothyroidism,bronchial asthma and moderate anemia.All cases had cough and fever,which was productive cough and hyperpyrexia(5 cases).All cases had tachypnea,which presented at the course of 0.5～6 days and progressively aggravated to respiratory failure 3～24 hours later.Chest x-ray showed localized exudation,which was similar to mycoplasma pneumonia.Seven cases had increased percentages of neutrophil.Six cases had increased CRP.All cases had respiratory failure;two cases were complicated with toxic encephacopathy.Treatment included anti-virus and support therapy.All cases received immunoglobulin and some cases received glucocorticoid.Six patients received mechanicai ventilation.Time of mechanical ventilation was 3～6 days.No patients died.Conclusion Pediatric severe influenza A(H1N1)case is severe pneumonia with characteristic of severe hypoxemia.Acute respiratory distress syndrome and death can be prevented through effective and in-time therapy.
