Carbon Monoxide Exposure Can Be Reduced During Routine Anesthesia in Kids

30.04.2010
Anesthesiologist identifies two changes to standard of care to protect developing brains

Doctors at Children’s National Medical Center have found that carbon monoxide levels in the blood of young children increase during routine general anesthesia. Anesthesiologists have found for the first time that, under certain circumstances, infants and children may be exposed to carbon monoxide during routine anesthesia resulting in a rise in the carbon monoxide levels in the child’s blood.

Because carbon monoxide can be generated as a byproduct of anesthesia, anesthesiologists world-wide use specific precautions to prevent and limit its production, according to Richard J. Levy, MD, Chief of Cardiac Anesthesiology, at Children’s National. Dr. Levy’s team identified the conditions in which carbon monoxide may be inhaled during anesthesia:

The first study demonstrated that carbon monoxide detected in the breathing circuit correlated with the increase in blood levels in children 2 years and older. The study included 15 patients between 4 months and 8 years.
The second study identified that the patient’s own exhaled carbon monoxide may be “re-breathed” during low-flow anesthesia – the current standard of care – where fresh gas flows more slowly into the circuit, rather than rapidly.

“The main goal is to provide the safest environment for young patients who require surgery,” said Dr. Levy. “We have identified tangible ways to reduce the risk of carbon monoxide exposure, and our hope is that these changes will be implemented internationally.”

Much remains unknown about the effects of low-dose carbon monoxide exposure on the developing brain. Several recent studies have suggested there may be a link to hearing impairments. Though there is more research to be done to determine these impacts, Dr. Levy recommends two immediate changes that will eliminate the risk of carbon monoxide exposure in children:

In the anesthesia machine, use carbon dioxide absorbents that lack strong metal alkali and do not degrade inhaled anesthetics (avoids CO production risk)
Avoid of low-flow anesthesia (avoids CO re-breathing risk)
Following Dr. Levy’s study findings, Children’s National switched to the recommended absorbent to minimize the risk to patients. Although the sample size is small, the results are compelling and Dr. Levy believes changes should be implemented.

Dr. Levy’s research has been named the top study out of 600 at the International Anesthesia Research Society 2010 meeting, and won the John J. Downes Research Award for best abstract at the upcoming Society of Pediatric Anesthesia/American Academy of Pediatrics 2010 Annual meeting.

Children’s National Medical Center, located in Washington, DC, is a leader in the development of innovative new treatments for childhood illness and injury. Children’s has been serving the nation’s children for more than 135 years. Children’s National is consistently ranked among the best pediatric hospitals by U.S.News & World Report and the Leapfrog Group. For more information, visit www.ChildrensNational.org.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
