The results of mechanical ventilation for severe hyaline membrane disease (HMD), and the changes in technique which took place, during the 6-year period 1967-72 are described. A pilot study of the effect of hydrocortisone among the most severely affected infants showed no benefit. After the introduction at the beginning of 1970 of a regimen for ventilating the infants at low peak airway pressures, slow respiratory frequencies, and high inspiration: expiration ratios, there was a sudden increase in survival rate which was largely accounted for by a reduction in the incidence of bronchopulmonary dysplasia. Evidence is presented that in infants with HMD mechanical factors are more important than oxygen toxicity in the pathogenesis of this condition.
本文描述了1967年至1972年这6年间,对重症透明膜病(HMD)进行机械通气的结果以及技术上发生的变化。对病情最严重的婴儿使用氢化可的松的初步研究未显示出益处。1970年初开始采用一种通气方案,即对婴儿采用低气道峰压、慢呼吸频率和高吸气:呼气比进行通气,此后存活率突然上升,这主要是由于支气管肺发育不良的发生率降低。有证据表明,在患有HMD的婴儿中,机械因素在该病的发病机制中比氧中毒更重要。
