[Necessity to control endexpiratory CO2-concentration during laparoscopic sterilisation under general anaesthesia with controlled ventilation (author's transl)]

During laparoscopy and intraabdominal insufflation of CO2 cardio-respiratory accidents following increased PaCO2 are possible. The continuous measurement of endexpiratory CO2-concentration by infrared absorption spectrometry is a simple method for controlling the level of ventilation. Respiratory acidosis under controlled artificial ventilation during laparoscopy can thus be avoided.
