  • Recent developments- effecting the way we work, changing the way we have to think..growing evidence of air quality
  • Our job to culture the perfect embryo-1 embryo,one healthy child
  • Effect all unit…….Factors effecting are quality, personnel,goods glue paints
  • Also incubators separate power line
  • Embryo graded 1-5 PN on day1 Cleavage patterns Rate of first cleavage Blastocyst development, cell number, rate, inner cell mass aneuploidy
  • Embryo graded 1-5 PN on day1 Cleavage patterns Rate of first cleavage Blastocyst development, cell number, rate, inner cell mass aneuploidy

    2. 2. “ Your IVF program is only as good as the lab which supports it “ <ul><li>1. Air Quality in ART laboratory </li></ul><ul><li>2. Laboratory design </li></ul><ul><li>3. Quality Control in ART laboratory </li></ul><ul><li>Kosmogonia IVF services: </li></ul><ul><li>Consultation and Support Design and Operation of IVF laboratories Fully Trained Staff </li></ul><ul><li>Giles Palmer www.kosmogonia.gr </li></ul>
    3. 3. <ul><li>Air Quality in ART laboratory </li></ul><ul><li>Air in urban areas can contain high levels of pollutants such as carbon monoxide, nitrous oxide, sulphur dioxide and heavy metals. </li></ul><ul><li>Indoors, construction materials, MDF, PVC flooring, paints and adhesives constitute the major source of volatile organic compounds (VOCs) leading to the phenomenon called “sick building syndrome”. </li></ul><ul><li>Other sources of indoor chemical hazards are cleaning fluids, floor waxes, cosmetics and cigarette smoke. </li></ul>
    4. 4. <ul><li>Cohen et al (1997) illustrated that not only high levels of aldehydes and other noxious compounds are present in the IVF laboratory (higher than outside air and the average house) but also in the incubators. </li></ul><ul><li>Controlling air quality in an ART laboratory has shown beneficial effects regarding fertilization and embryo development (Boone et al., 1999). </li></ul><ul><li>In Europe the EU directive 2004/23/EC which stipulates quality requirements when Human tissue and cell are handled (a critical point being clean air) has lead to most centers making -at the very least- slight structural changes to their IVF units. </li></ul>
    5. 5. Formaldehyde Furniture: Upholstered furniture, carpets,plywood, pressed wood products 1,4-dichlorobenzene, naphthalene Air fresheners: Moth balls, deoderizers, Freons (trichlorofluoromethane, dichlorodimethane) Refrigerant: air conditioners, freezers, dehumidifiers Tetrahydrofuran, cyclohexane, methyl ethyl ketone, toluene, acetone, hexane, 1,1,1-trichloroethane Adhesives: PVC cement, contact cement, model cement Tetrachloroethene, perchloroethene, trichloroethene Fabric cleaners: Dry cleaned clothes, stain removers, leather cleaners Acetone, ethyl alcohol, isopropyl alcohol, methacrylates, ethyl acetate Personal care products : nail polish & remover, colognes, hair spray BTEX (benzene, toluene, ethylbenzene), hexane, cyclohexane, 1,2,4-trimeyhylbenzene Petroleum distillates: Paint thinner, oil-based paints, liquid insect pest products, furniture polishes Possible VOCs Products used in Home and work
    6. 6. <ul><li>National Health and Safety Authorities -safe limits of VOC exposure for humans/ guidelines for building ventilation-but there is little evidence in the IVF literature of the toxicological effect of these embryos in vitro. </li></ul><ul><li>Pollutants can settle on work surfaces and dissolve in aqueous solutions of embryo culture medium. Embryos, lacking an immune system, cannot protect themselves against these environmental contaminants . </li></ul><ul><li>Laboratory design - Control of the air quality may be hindered in an urban area, or units close to busy roads and car parks. Within a hospital difficulties may be encountered with working in an area adjacent to the Laundry, Sterilizing or Histology departments. </li></ul>
    7. 7. <ul><li>Regulations </li></ul><ul><li>EU Directive 2004/23/EC : Setting standards of quality and safety for the donation, procurement, testing, processing, preservation, storage and distribution of human tissues and cells- -to be implemented in all member countries. </li></ul><ul><li>Greek law 2008: ΠΔ 26/2 00 8 εναρμόνιση προς την οδηγίας 2004/23/ΕΚ . </li></ul><ul><li>Greek National Authority: Terms and Conditions of licensing Assisted Reproduction Units. </li></ul><ul><li>-awaiting final approval. </li></ul><ul><li>Air quality effect on embryos </li></ul><ul><li>Ambient air and its potential effects on conception in vivo. </li></ul><ul><li>Cohen Hum.

    14. 15. Renovation of Laboratory <ul><li>“… can introduce a variety of compounds into the work place and emission of harmful compounds used in finishing can have an adverse effect on embryo development and pregnancy rate either temporarily or long term! ” </li></ul><ul><li>Removal of wooden furniture: replace with stainless furniture and workbenches used in pharmaceutical electronic and food industry. </li></ul><ul><li>Avoid: alkanes, aromatics, alcohols, aldehydes and ketones. </li></ul><ul><li>Adhesives/Vinyl Glue used for floor covering are available solvent free with low VOC emissions. </li></ul>
    15. 16. Renovation of Laboratory <ul><li>No difficult to clean corners and ledges, no sliding doors, sinks and drains. </li></ul><ul><li>Lighting should be within sealed lighting units. </li></ul><ul><li>Partition Wall systems/ non-porous material such as Corian® panels -expensive but provide inert, hypoallergenic, </li></ul><ul><li>Ducts/ pipes can be hidden between wall panels or covered. Sealed doors and pass through windows may help these critical steps. </li></ul><ul><li>Avoid copper-inert stainless steel tubing certified for the use with medical gasses is now recommended. </li></ul><ul><li>Changing rooms-clean as possible,flushed with filtered air/ adjacent to lab. </li></ul><ul><li>Positive pressure- easier to maintain and not less velocity if the adjoining operating theater also has sealed doors and ceiling. </li></ul><ul><li>New equipment- should be “run in” to dissipate latent VOCs produced in their manufacture. </li></ul><ul><li>This may make the difference between a poor initial pregnancy rate or triumphant start to a new IVF unit! </li></ul>
    16. 17. Unseen Dangers <ul><li>Compressed gas can contain harmful compounds such as benzene, isopropanol and pentane (Cohen.1997). </li></ul><ul><li>As high levels of VOCs have been shown to be present incubators, (Hall et al 1998., Mayer et al 1999). </li></ul><ul><li>Anesthetic gasses use in oocytes retrieval- linger in the air. </li></ul><ul><li>Mobile units Coda/ Zander. </li></ul>
