Comparative Study[Lung function in pregnant patients and its significance for anesthetic ventilation in cesarean section].
Spirometry was conducted preoperatively in a group of 10 women subjected to cesarean section. The measured minute ventilation served as basis for ventilation under anaesthesia. ⋯ The maternal carbon dioxide level assumes the significance of a guiding value for the choice of the ventilation parameters. If the spirometric initial data and the actual pCO2 value under anaesthesia are not known, it is recommended to employ a minute ventilation of 11.5 l/min.

The goal of any anaesthesiologist delivering anaesthesia to patients with pre-existing lung disease has to be the prevention of intra- and postoperative complications. Changes in gas exchange imposed by anaesthesia and surgery can cause dangerous disturbances in oxygen transport and in acid-base balance. Uptake and elimination of volatile and gaseous anaesthetics depend upon normal respiratory function. Any marked impairment can considerably modify the kinetics of these processes.
