[Severe respiratory distress with stubborn hypoxemia in newborn infants whose mothers had had placenta previa].
The study of 16 newborn of birthweight less than or equal to 2,200 g characterized by a common point: the presence of PLACENTA PRAEVIA IN THE MOTHER, enabled us to come to grips with the severe respiratory distress that these newborn can have. From the clinical standpoint: there is always early respiratory distress. From the radiological standpoint: by far the most dominant pathology was interstitial edema, giving rise to a WET LUNG. From the biochemical standpoint: the blood gases were characterized in a certain number of cases by hypoxemia which was refractory to the usual forms of treatment. From the mechanical standpoint: measurements carried out in 4 patients confirmed the extraordinary fall in these patients' compliance. The clinical, radiological, blood gas and mechanical analysis enabled one to differenciate 2 main types of indications for artificial ventilation: -- acute hypoxemia, -- the idea of an increased need for oxygen. In these 2 types of indications for artificial ventilation, it was apparent that the treatment of choice is constant positive pressure which may or may not be combined with intermittent positive pressure. With this treatment technique, none of the patients progressed to massive atelectasis. It can be said that with the advent of techniques of ventilation by high pressure combining IPP with CPP, one has definitively eliminated from this pathological picture, the principal cause of death: --anoxia due to massive alveolar collapse.
