  • Title: [Perinatal mortality and asphyxia in premature babies (author's transl)].
    Author: Werle P, Künzel W.
    Journal: Z Geburtshilfe Perinatol; 1975 Aug; 179(4):250-60. PubMed ID: 241163.
    Abstract:
    The aim of the present investigation was to study the influence of O2-ventilation, blind buffer therapy with Na-bicarbonate, late cord clamping and infusion of low molculare weight dextran on morbidity of Respiratory-Distress-Syndrom (RDS) and mortality during the first week in infants with a birthweight of 2500 g and less. The charts of 536 infants were studied. There were 481 life birth and 55 stillbirth (10.2%). In 185 infants the pH and Base-excess in the umbilical arterial blood was meassured. The infants born in 1969--1971 were compaired with them born in 1972--1973. In 52% of the "premature infants" the pH was 7.25 U and lower and in 90% of the Base-Excess was --4.5 meq/l and more. The perinatal mortality (PM) was 30% and 13% (P less than 0.01) resp. There was a correlation to the birthweight. The decrease of the PM was related to the fall in mortality of infant during the first week: 21% and 4% resp. Here too, there was a correlation to birthweight and gestational age. The morbidity in RDS: 20.6% and 10.0% (P less than 0.01) and mortality following RDS: 79.3% and 35.0% resp. (P less than 0.01) was also low in 1972--1973. The results permit us to conclude that it is of great importance to correct fetal acidosis immediately after birth to prevent irreversible alterations in the lung. It could also be of value to encrease cardiac output and lungperfusion by late cord clamping and injection of dextran 40. The other procedures belong to standard managment in handling an asphyxiated fetus.
