[Metabolic effects of maternal hyperventilation in obstetrical anaesthesia induction (author's transl)]. 1981

D Kalinkov, and S Kalinkov-Koehl

Apparative hyperventilation before intubation brings about a favourable blood gas situation, but also a bicarbonate shortage, causing metabolic acidosis with increase of blood lactate and pyruvate. In obstetrics a mother-fetus infusion of lactate can occur, which can produce fetal distress. Because of the relative immaturity of the enzyme systems in the newborn, degradation of the infused lactate proceeds very slowly. These children recover only gradually over a period of several hours. For this reason it appears advisable to hyperventilate only briefly before a quick obstetrical intubation.

D012121	Respiration, Artificial	Any method of artificial breathing that employs mechanical or non-mechanical means to force the air into and out of the lungs. Artificial respiration or ventilation is used in individuals who have stopped breathing or have RESPIRATORY INSUFFICIENCY to increase their intake of oxygen (O2) and excretion of carbon dioxide (CO2).
