Comparative Study[Acid-base balance in the newborn infant. II. 3 technics of sample collection and the difference between amniotomy].
The study included 32 healthy newborns to evaluate the acid-base balance between two groups of newborns whose mothers underwent early or late amniotomy. The results were compared to the first study finding important differences, unquestionable due to amniotomy and age. ⋯ With the criterion pointed out in this work, the usefulness of late amniotomy and the stabilization of acid-base balance is established in newborns under 4 hours of age. Arterial blood is still being proposed to obtain an "ideal" acid-base balance and the arterialized capillary as a practical and useful method.

Comparative Study[Salicylate poisoning. Determination of the free fraction using the ultrafiltration method].
Seventeen infants under one year of age admitted to the Emergency Service of the General Hospital of the Medical Center La Raza during the year 1976 were included in this study with the diagnosis of salicylate poisoning. Determination of plasma salicylate by the ultrafiltrate method was practiced to all patients. A direct relationship between total plasmatic salicylate and its free fraction was found together with an inverse proportion between percentage of total free--salicylate and plasma pH and a lineal correlation between plasma free--salicylate and salicylate obtained in spinal fluid. It is concluded that determination of the free fraction of plasma salicylate is an easy diagnostic method for the better evaluation of salicylate acid poisoning in the infant.
