[The support of adequate maternal and fetal gas exchange during abdominal delivery under endotracheal anesthesia]

Fetal gas exchange and a neonate's status were found to be closely related to the capacity of controlled maternal pulmonary ventilation during abdominal delivery. To calculate the minute volume of ventilation, correction factors were proposed. The optimization of gas exchange during an operation was provided by sombrevin. The proposed procedure decreased the incidence of fetal hypoxia and neonatal asphyxia.
