The purpose of this study was to evaluate the degree of respiratory depression in the newborn caused by the drugs given to the mother during anesthesia for cesarean section. Two types of induction were compared, one with barbiturate (hexobarbitone) and the other with nitrous oxide, both followed by succinylcholine for intubation. Blood gases were studied in the mother at the time of delivery, and in the child repeatedly during a period of 3 h after the delivery. The infants were delivered by elective cesarean section. There were 16 in the barbiturate group and ten in the nitrous oxide group. The maternal blood gas values were compatible with values in non‐anesthetized adults. The results in both groups of infants were compared with each other and with results from infants after normal vaginal deliveries. The three series show a close correlation, but infants in the barbiturate group had significantly higher Pa o2 values during the first 3 h of life, higher Pa co2 values during the first 10 min, and complete normalization after 30 min, when compared with the vaginally delivered group. The nitrous oxide group did not show any significant difference from the barbiturate group, either in Apgar scores or blood gas values in the infants. Both techniques allow normal oxygenation of the infant immediately after delivery. On the other hand, mothers in the nitrous oxide group had a higher incidence of negative psychic reactions to anesthesia in comparison with the mothers given barbiturate.
