[Cardiorespirography in physiologic and pathologic premature infants].
The cardiorespirography investigation, carried out in 42 premature newborn has led to the following results: 1. The narrowed undulatory zone was stated more frequently in cases of prematurely born infants, than in those of mature ones.--2. A silent zone was a typical phenomen with pathological prematurely born infants. The silent zone of type b together with tachypnoe and apnoic attacks and decelerations, prevailed within the group of infants suffering from IRDS. A typical silent zone of type a together with bradycardia, bradypnoe and apnoic attacks without decelerations was found in infants with the symptoms of intracranial haemorrhage. There were observed the silent zone of type a and of type b in cases of severe neonatal infections. But apnoic attacks with decelerations proved to be more frequent than in cases suffering from IRDS and intracranial haemorrhage. The respiratory curves showed an accentuated respiratory periodicity.--3. Whereas in cases of infants with IRDS the correction of the acid base balance brought about the correction of CRG--a gradual passage from the silent zone of type b to the undulatory one, the correction of the acid base balance did not bring about any change in the type of the silent zone within the group of cases of infants suffering from intracranial haemorrhage.--4. The cardiorespirography would therefore be suitable to be used, in relation to acid base balance values, as an additional method of establishing differential diagnosis in neonatal pathological cases.
