Anaesthetic machine preparation for MH-susceptible patients and MH crisis management.

  • Preparation of any anaesthesia workstation in less than 90 seconds for a known MH patient – Saves time/money as flushing can take 20 minutes normally

  • Allows Vapour-Free anaesthesia machine/s to be used elsewhere, instead of being kept on stand-by and un-utilised – Saves money and time by not having to secure the machine

  • Can be used for a crisis situation case where MH was not previously known – can help save lives

Prevent a Malignant Hyperthermia Crisis

Newer anaesthetic gas machines contain plastic and elastomeric components that absorb volatile anaesthetics and then release residual vapour during subsequent anaesthetic procedures. The anaesthetic gas machine requires high flows and a lengthy time period to remove most of the vapour before the machine can be used for a patient that cannot tolerate breathing trace amounts of volatile anaesthetic vapour. Furthermore, the Vapor-Clean filters are MRI safe (the same instructions for use are applicable for regular theatre use and MRI use).

The Vapor-Clean filters absorb the trace amounts of anaesthetic vapour (isoflurane, sevoflurane and desflurane) so that anaesthetic vapours do not reach the patient. Placement of the Vapor-Clean filter canisters on the anaesthetic machine allows the machine to be immediately vapour-free (less than 5 parts per million of vapour).

Key features:

  • Compatible with most Anaesthesia Machines
  • Ready in Under 90 Seconds
  • Two-Year Minimum Shelf Life
  • Suitable for use with MRI
  • Negligible Additional Breathing Circuit Resistance
  • No Need to Remove CO2 Absorbent
  • Compatible with Both Standard Two-Limb and Coaxial Breathing Circuits

How does the Vapor-Clean remove anesthetic vapors?

The Vapor-Clean filter canisters contain granules of medical grade activated charcoal.  Volatile anesthetic vapor molecules are captured and held by the activated charcoal granules.

Can the Vapor-Clean be reused?

No.  The Vapor-Clean is a single patient use device.  A new set of Vapor-Clean filters should be used for each patient.  At the conclusion of the anesthetic procedure, the Vapor-Clean filters should be discarded.

Can the Vapor-Clean be used if Malignant Hyperthermia (MH) is detected intra-operatively?

Yes. Installation of the Vapor-Clean intra-operatively removes residual anesthetic vapors emitted by the anesthesia gas machine as well as vapors emitted by the patient.  Placement of the Vapor-Clean at any time ensures that no vapor will be inhaled by the patient.

Does the Vapor-Clean work with all anesthetic gases?

Yes.  The Vapor-Clean has been tested and proven effective at removing >99% of isoflurane, sevoflurane and desflurane.

What is the shelf life of the Vapor-Clean?

The shelf life is a guaranteed minimum of two years.

How soon after installation of the Vapor-Clean is the anesthesia gas machine free of trace anesthetic vapors?

Tests showed that the concentration of vapor was less than 5 parts per million in less than 2 minutes.

Why does the Vapor-Clean include two activated charcoal filters?

The primary reason for including two filters is to increase anesthetic gas removal in the intra-operative application.  Additionally, the dual filter prevents inhalation of vapor in case one of the anesthesia machine’s non-rebreathing valves fails.  An additional safety reason for the dual filter configuration is to minimize the possibility of inadvertent placement of a single charcoal filter  on only the expiration hose port.

Has the Vapor-Clean been cleared by the Food and Drug administration?

Yes.  The Vapor-Clean has been cleared by FDA for removal of unwanted anesthetic vapors.  The 510(k) clearance number is K092031.

During development, was the Vapor-Clean tested on actual malignant hyperthermia-susceptible patients?

No.  The Vapor-Clean was not tested on actual MH susceptible patients.  However, it has been demonstrated effective at removing >99% of anesthetic vapors in rigorous bench testing, and has been used successfully on many MH-susceptible patients worldwide since its introduction.

Which anesthesia gas machines require Vapor-Clean filters?

Published studies show that the newer Draeger anesthesia gas machines (Primus, Apollo, Fabius) and GE-Ohmeda (Aestiva) require 50-75 minutes of continuous gas flush at 10 L/min before residual vapor concentrations are less than the save level of 5 parts per million.  It is likely that other new machines that contain plastic parts require similar preparation times.

What is the source of residual anesthetic vapor in the anesthesia gas machine?

Plastic parts (valves, tubing, bellows, etc.) within the anesthesia gas machine absorb anesthetic vapor.  These absorbed gases are then slowly released when the machine is used for a new patient during a subsequent anesthetic procedure.

Does use of the Vapor-Clean during a MH case eliminate the need for dantrolene to be given?

No.  The Vapor-Clean only clears the anesthesia machine of trace anesthetic agents that can trigger MH.  Dantrolene is still required to treat the disease process of MH.
