CO2 Absorbent Study Shows CO w Fresh Medisorb!

Pediatric Circuit with Gas Sampling Elbow, Fixed Wye, 1 Liter Bag, Filter

Key findings from 2010 study on CO2 absorbent surprisingly ignored!

Detection of Carbon Monoxide During Routine in Infants and Children

Richard J. Levy, MD,* Viviane G. Nasr, MD,* Ozzie Rivera, BS,† Renee Roberts, MD,* Michael Slack, MD,‡ Joshua P. Kanter, MD,‡ Kanishka Ratnayaka, MD,‡ Richard F. Kaplan, MD,*and Francis X. McGowan, Jr., MD§ (Anesth Analg 2010;110:747–53)

Excerpts and quotes from the study:

Carbon Monoxide was detected routinely during general anesthesia in infants and children when using fresh GE Medisorb, a soda lime. (It has long been known that CO is produced in desiccated soda lime yet surprising to be found when using fresh soda lime.)

Carbon Monoxide is a known neurotoxin. Exposure to low concentrations of CO (12.5ppm) can cause neurotoxicity in the developing brain and may lead to neuro developmental impairment. Peak CO levels measured in the anesthesia breathing circuit were in the range thought to impair the developing brain.

The study suggests that use of carbon dioxide adsorbents that lack strong metal hydroxide (ie. the Amsorb Plus CO2 absorbent) could limit inspired CO if detection was attributed to degradation of volatile anesthetic. …findings suggest the use of carbon dioxide absorbents that lack strong metal hydroxide (the Amsorb Plus CO2 absorbent does not use strong metal hydroxides).
Young children exposed to inhaled anesthetics were twice as likely to develop behavioral or developmental disorders after exposure.

The study measured CO levels in the circuit and in the blood stream via COHb.

CO binds 240 times more avidly to hemoglobin than oxygen.

The APSF recommends using adsorbents that do not use strong metal hydroxides(sodium hydroxide), (the Amsorb Plus CO2 absorbent does not use strong metal hydroxides or sodium hydroxide).

The APSF recommended not using absorbents based on strong alkali or metal hydroxides. The Amsorb Plus CO2 absorbent does not contain strong alkali or metal hydroxides and is thus recommended by the APSF.

Nasal Alar Pulse Oximetry Sensor

Like other anesthesia pulse sensors, the Nasal Alar Pulse Oximetry Sensor from Bell Medical is designed for low profusion patients and multi-day stay ICU patients. The Nasal Alar Pulse Oximeter Probe is FDA approved for up to 28 days on a patient.

The Nasal Alar Pulse Oximeter Probe is lightweight and comfortable to wear. Patients LOVE IT!

Nasal Alar Pulse Oximetry Sensor works on the most challenging patients!

Reliable accuracy – unaffected by poor peripheral perfusion or low saturations with Nasal Alar Pulse Oximetry Sensor

This oxygen and pulse sensor fits comfortably on the fleshy part of the side of the nose. The site is fed by both the external and internal carotid arteries; the latter also provides blood to the brain. The rich vascular supply to this region provides a strong, reliable signal, even when it is difficult or impossible to get a signal at the fingertips.

Monitoring Site results in faster detection of oxygen saturation changes with Nasal Alar Pulse Oximetry Sensor

Because the Nasal Alar Pulse Oximeter Probe measures the oxygen saturation from a vessel also supplying blood to the brain, changes have been proven to be detected up to 30 seconds faster than with a finger sensor.

Improved patient comfort with Nasal Alar Pulse Oximetry Sensor

The hands-free Alar oxygen and pulse sensor does not impede normal patient functions such as eating, drinking, or talking. It is less bothersome to the patient and is not likely to become disconnected.

Cost effective and convenient with Nasal Alar Pulse Oximetry Sensor

The single-patient-use Alar Sensor does not use adhesives at the sensor site. The sensor can be removed and reapplied for up to 7 days saving hospitals up to $232 for the ICU patient. Proven accuracy reduces false alarms improving patient safety, patient satisfaction and nurse productivity.

Amsorb Plus CO2 Absorbent

Amsorb Plus CO2 Absorbent improves patient safety by eliminating potential toxins plus it provides permanent color change so you always know the status of your absorbent. Your health organization is currently using GE Medisorb which is a traditional sodalime that can produce toxins when desiccated or fully spent. Since your facility does not change your absorbent until you have a reading of over 5 mmHg inspired CO2 the risk of exposure to toxins such as Compound A, Carbon Monoxide and Formaldehyde is increased. With Amsorb Plus you can continue to push your absorbent to complete exhaustion with no worry of toxins. Because Amsorb Plus CO2 Absorbent produces no toxins ever, your clinicians may also deliver lower flows while administering Sevoflurane and thus save the hospital system thousands. Amsorb Plus CO2 Absorbent is part of many health systems “green initiative” because Amsorb Plus has a lower pH than sodalimes such as GE Medisorb when spent. Amsorb Plus is NOT a sodalime. Amsorb Plus CO2 Absorbent is safe for the environment and safe for landfills. GE Medisorb and sodalime are often required to be “red bagged” for incineration at great expense due to spent sodalime’s high pH (see attached Kaiser Permanente disposal document).

Amsorb Plus CO2 Absorbent

Amsorb Plus offers numerous benefits at no additional cost for the actual absorbent. We offer Amsorb Plus CO2 Absorbent under our price matching program that guarantees savings since you save on anesthetic agent and on product disposal.

Bell Medical would be happy to provide you with product to conduct your own evaluation and trial with the hopes that your positive experience would allow Amsorb Plus to be considered as a product of choice. Please review the attachments and let us know how best to proceed with a local or corporate evaluation. Thank you for your interest and support.
