保护性肺通气对婴儿围体外循环期肺功能的影响

Objective To investigate the impact of static inflation and intermittent ventilation on lung function peri-cardiopulmonary bypass(CPB) in infants.Methods Sixty infants of less than 1-year-old,with ventricular septal defect were selected to assigned to two groups:the treatment group(n=30),given static inflation and intermittent ventilation once every 10 minutes during CPB;the control group(n = 30),no ventilation during CPB.Indicators of pulmonary function including OI,PaO2/PAO2,A-aDO2 and RI were recorded before CPB and 2 h,6 h,12 h,24 h and 48 h after CPB.Results At 2 h,6 h,12 h after CPB,OI and PaO2/PAO2 of the treatment group were higher than those of the control group(P＜0.05).A-aDO2 of the treatment group was lower than that of the control group at 2 h,6 h,12 h,48 h after CPB(P＜0.05).RI of the treatment group was lower than that of the control group at 6 h,12 h after CPB(P ＜0.05).Conclusion Static inflation and intermittent ventilation during CPB can improve early oxygenation of lung,and have good lung protection in infants.

鼻塞式呼吸机间歇指令通气联合肺表面活性物质治疗早产儿肺透明膜病的临床研究

Objective To evaluate the effect of nasal intermittent mandatory ventilation (NIMV)combined with pulmonary surfactant for the treatment of hyaline membrane disease in premature children and to compare the clinical efficacy with conventional mechanical ventilation and continuous positive airway pressure (CPAP). Methods Seventy-four babies with severe respiratory syndrome were given curosurf[100 mg/(kg·dose)],25 of them were given to NIMV, another 25 were given conventional intermittent mandatory ventilation (IMV), the last 24 patients were given conventional CPAP. Blood gas analysis parameters and incidences of respiratory complications including respiratory tract infection and chronic lung disease,frequent apnea and carbon dioxide retention, were compared among the three groups. Results After treatment of 1 h, symptoms and signs of the patients markedly improved. All the three groups showed an increase in arterial oxygen partial pressure, but arterial pressure of carbon dioxide and oxygen index decreased significantly by the time of 6,12,24 h after treatment and there were not significantly difference among the three groups. The rates of respiratory infection and chronic lung disease in NIMV group were less than that of conventional IMV group[(8% vs 36% ) ,(20% vs 72% )],the rates of frequent apnea and carbon dioxide retention in NIMV group were less than that of CPAP group[(8% vs 36% ), (20% vs 72% )]. Conclusion NIMV combined with pulmonary surfactant is a potentially efficient therapy for hyaline membrane disease in premature infants. NIMV treatment of hyaline membrane disease in premature infants can reduce or avoid ventilation-associated pneumonia,chronic lung disease and other complications,but also efficiently reduce the incidence of frequent apnea and carbon dioxide retention.
