Newer Considerations in Air Embolism During Operation

Transcutaneous Doppler Ultrasonic Flow Detectors for Diagnosis of Air Embolism

“…Changes in the central venous pressure (CVP) were not impressive until large quantities of air (2 in/kg) had been injected. Tisovec & Hamilton (1967) have suggested that a rise in CVP can be an early sign of air embolism and Michenfelder et al (1966) have been able to aspirate air from the CVP catheter. These have not been our experiences in the dog.…”

Automatic Measurement of Blood Pressure without Arterial Puncture

“…Nevertheless, under reasonably favourable conditions, instruments such as the H1matonograph can give days or even weeks of regular measurements, with a degree of reproducibility which would be difficult and very laborious to attain using manual methods. The incidence of venous air embolism in patients having suboccipital craniectomies in the sitting position is variously quoted as 1-15% (Hunter 1962, Michenfelder et al 1966, Tisovec & Hamilton 1967. The diagnosis depends on the detection of changes in the cardiopulmonary system or of the murmur and alterations in heart sounds produced by the air bubbles.…”

Embolia gasosa em neurocirurgia
