comparison of air, oxygen and carbon dioxide embolization

Comparison of air, oxygen and carbon dioxide embolization. Arnold Kunkler, M.D., Harold King, M.D.

From the Department of Surgery, Indiana University School of Medicine , Indianaolis, Indiana. Annals of Surgery 1959.

"When compared with air, carbon dioxide is about 34 times as soluble in water at 30 degrees centigrade. It is only slightly less soluble in serum at 38 degrees. This probably explains why the carbon dioxide embolus is so unstable."

"This study gives support to the simple clinical procedure of bathing the field of operation in an atmosphere of carbon dioxide gas. Since it is 1.53 times as dense as air, it should largely displace air in the operative field."

Significance of air embolism during cardiopulmonary bypass

THE SIGNIFICANCE OF AIR EMBOLISM DURING CARDIOPULMONARY BYPASS. 

F.C.Spencer, M.D., N.P. Rossi, M.D., Shao-Chi Yu, M.D., and J.A.Koepke, M.D., Lexington, Ky.

"It was repeatedly noted, however, that the disappearance of visible air did not always indicate restoration of normal myocardial capillary blood flow. The areas of cyanosis remained much longer than did the visible air bubbles."

"In some experiments with repeated air emboli, areas of cyanosis persisted and were associated with progressive heart failure."

"With visible air bubbles in a failing heart, the injury was obvious. By contrast, though, was the occasional persistence of a feebly contracting cyanotic heart after all visible air had disappeared. This was probably due to widespread capillary occlusion from microscopic emboli. It was clear, though, that if the earlier air emboli had not been seen, the origin of the cardiac injury would have been obscure and could have been erroneously attributed to a number of causes - metabolic acidosis, rate of perfusion, gas or silicone emboli from pump oxygenator, et cetera"

Venous embolization during sternotomy

Venous emobolization during sternotomy in children undergoing corrective heart surgery.

Ilan Keidan, MD, Yael Mardor, PhD, Sergei Preisman, MD, and David Mishaly, Tel Aviv, Israel.

The Journal of Thoracic and Cardiovascular Surgery. 2004.

"VAEs were detected in 14 (70%) patients."

"The peak number of emboli appeared approximately 5 seconds after sternotomy and returned to baseline at the end of the procedure."

"The fact that embolus incidence was higher with the saw compared with the scissors is not straightforward."

"In summary, our results suggest that VAE during sternotomy is a frequent occurrence and that the number of emboli is related to the method of sternotomy."

"Neurologic injury after cardiac surgery is principally associated with emboli"

"Neurologic injury us a leading cause of morbidity subsequent to cardiac surgery and is thought to be principally the result of embolization"

"In conclusion, we have demonstrated that even with the advances in circuit design, emboli may still be detected in large numbers on CPB and may be associated with discrete processes of the perfusionist's care."

Vascular air embolism: A silent hazard to patient safety

Vascular air embolism: A silent hazard to patient safety.

Brull SJ, Prielipp RC. Journal of Critical Care 2017. 

"VAE may be introduced through disruption in the integrity of the venous circulation that occurs during insertion, maintenance, or removal of intravenous or central venous catheters. VAE impacts pulmonary circulation, respiratory and cardiac function, systemic inflammation and coagulation, often with serious or fatal consequences. When VAE enters arterial circulation, air emboli affect cerebral blood flow and the central nervous system. New medical devices remove air from intravenous infusions. Early recognition and treatment reduce the clinical sequelae of VAE. An organized team approach to treatment including clinical simulation can facilitate preparedness for VAE. The MAUDE database included 416 injuries and 95 fatalities from VAE. Data from the American Society of Anesthesiologists Closed Claims Project showed 100% of claims for VAE resulted in a median payment of $325,000."

"High sensitivity, apparently, allows early detection of VAE, without bringing the episode of air embolism to the development of clinical signs. This is evidenced by the large difference between the overall frequency of VAE and clinically significant VAE, which according to the results of the study was 52% and 7.1%, respectively."

"This is the first report in an adult

human to document an exact lethal volume of air, 200 ml (albeit in a patient with congestive heart failure), rather than to estimate retrospectively the lethal

lethal to healthy adult humans."

"Although the incidence of venous air embolism and paradoxical air embolism during hepatic resection is unknown, VAE is a potentially hazardous complication during hepatectomy. Many patients who undergo hepatectomy have liver cirrhosis, and VAE is particularly dangerous in such patients because 15-45% have pulmonary abnormalities including intrapulmonary shunting caused by pulmonary vascular dilation and arteriovenous communication. In these patients, paradoxical emboli can occur during air embolism even if intracardiac abnormalities are not present."
