[Effects of various anesthesia procedures used in forceps delivery on the cardiopulmonary adaptation of the newborn infant. 2. Modification of pulmonary adaptation].

Mature newborns reveal the same pulmonal adaption to extrauterine conditions after forceps delivery in general anesthesia for the mother beginning with propanidid or hexobarbital as newborns after spontaneous delivery. Intervalls of apnoe, being physiological during neonatal adaption up to the fourth life-hour, occurred in all three tested groups in the same frequency. Genuine apnoe in combination with following bradycardia and cyanosis couldn't be observed. Moreover during the whole examination time all mean values of respiration frequency were physiological. Therefore we believe that there is no fundamental deterioration of newborns respiration, i.e. a depression in nerve-centre, caused by propanidid or by hexobarbital, despite of repeatedly contrary description.
