Acid-base balance and blood gases changes and "lactate excess" in acute respiratory alkalosis during general anaesthesia.
In 40 young males aged 18-20 years operated on for inguinal hernioplasty acute respiratory alkalosis was obtained in the 45th minute of general anaesthesia. The values of basic acid-base balance parameters, blood gases, pyruvate and lactate levels and "lactate excess" were determined before and after hyperventilation. ⋯ No changes were observed in the oxygenation of capillary blood and the values of "lactate excess" were normal which rules out tissue hypoxia during acute respiratory alkalosis. Passive hyperventilation being a less dangerous alternative of hypoventilation is a frequent occurrence during general anaesthesia and it causes transient respiratory alkalosis.
