[The technique of anesthesia for the prevention and treatment of gaseous embolism in the neurosurgical sitting position (author's transl)].
The sitting position in neurosurgery gives always three problems for the anaesthesist: --maintain the cerebral perfusion pressure, --not to aggravate intracranial hypertension, --detect gaseous embolism. The clinical signs of air embolism often look like the awakening of the patient. That is why it is necessary to use specific methods to detect them: Doppler, Swan-Ganz catheter, and/or continuous CO2 recording of expired air by capnograph. Among the various methods to prevent air embolism we have used controlled respiration with a positive and expiratory pressure (P.E.E.P.). In our series (45 operations) gas embolism occurred in 13% of the patients operated upon without positive and expiratory pressure, and 0% with P.E.E.P.
