  1. A RandomizEd Trial of ENtERal Glutamine to MinimIZE Thermal Injury Laboratory Training

  2. Lab Manual p 4 Blood Sample Overview All patients will have blood samples taken unless they refuse consent For DNA studies, lymphocyte function studies, inflammatory cytokines & heat shock proteins

  3. Lab Manual p 4 Blood Draws • Blood Draws • Draw 1 (4 days post start of study intervention) + 48 hrs • Draw 2 (7days post start of study intervention) ± 48 hrs • Draw 3 (14 days post start of study intervention) ± 48 hrs • Draw 4 (21 days post start of study intervention) ± 48 hrs If a draw can not be obtained due to a weekend, draw on the closest working day • Draw from a central line • If no central line, draw with routine blood work • DO NOT draw blood: if no central line & no scheduled blood draw Remember: Do NOT draw blood within a period of 12 hrs after surgery or blood transfusion. OK to draw before surgery

  4. Lab Manual p 5, 6 Materials Provided • Lab Kits (4 kits per patient) each containing: • 2 Heparin CPT tubes • 1 Citrate CPT tube • 1 Sodium Heparin tube • 1 Paxgene DNA tube (Kit # 1 only) • 30 Cryovials • 40 Labels * For expired tube replacement contact Elizabeth Luzier (Lab Manual p 7)

  5. Lab Manual p 5 Materials Needed • Centrifuge: variable speed • Pipette: calibrated for 50 to 500 microlitre pipetting • - 80° C (-112° F) Freezer • Phosphate Buffered Saline (PBS) • Dimethyl Sulfoxide (DMSO) • 0.9% Normal Saline Solution • 15 ml conical tubes • Timer • Ice • Gloves • Biohazardous waste disposal system Supplies for shipping specimens on dry ice

  6. Lab Manual p 7 Cryovial/Tube Labels • Each kit will contain enough labels for each cryovial/tube • Add one label to each cryovial/tube used • Label includes an ID as follows

  7. Lab Manual p 8 Lab Sample Log Labels Add to labels: • enrollment number • date and time of the blood draw

  8. Lab Manual p 8 Blood Draw Preparation BEFORE drawing blood: • Ensure all necessary materials and equipment are present (including a cup/container of ice bedside) • Fill out and affix labels to tubes

  9. Lab Manual p 8 Blood Draw Order • Draw blood in the following order:  • (1) 2 x Red/green speckled top tubes • (2) 1 x Blue/black speckled top tube • (3) 1 x Green top tube • (4) 1 x PAXGENE tube(1st draw only) • Invert all tubes 8-10 times • Place Green Top tube (sodium heparin) only on ice immediately and keep it on ice until further processing (do not exceed 30 minutes)

  10. Green Top Tube (Sodium Heparin) Lab Manual p 9, 16 Process within 30 minutes of collection • Step 1: • Remove green top tube from ice and place in centrifuge • Centrifuge at 1000 RCF (g) for 5 minutes • If red cells are re-suspended in plasma when removing tube from centrifuge, repeat centrifuge process above. Step 2: • Pipette plasma in 500μL (0.5 mL) aliquots into 4 green topped cryovials Step 3: • Place cryovials in - 80° Cfreezer • Store at - 80° C (-112°F) until shipment to central lab

  11. Lab Manual p 16 Green Top Tube (Sodium Heparin)

  12. Lab Manual p 10, 17 Speckled Red/Green & Blue/Black Top tubes Keep at room temperature and process within 2 hours • Centrifuge for 30 minutes at room temperature at 1800 RCF • Pipette off the plasma without disturbing the cell layer • Aliquot 500μL of plasma from the Blue/Black top tube into each of the 8 labeled (ACD) orange cryovials • Aliquot 500μL of plasma from Red/Green top tubes into each of the 16 labeled red cryovials • Freeze at – 20° C (-4°F) for 1 day • Store at -80° C until shipping

  13. Speckled Red/Green Top & Blue/Black Top tubes Lab Manual p 17

  14. Speckled Blue/Black Top Lab Manual p 11, 18 Using the already processedBlue/Black top tube: • Gently re-suspend the cells above the gel barrier • Transfer into 2 labeled (ACD PBMC) orange cryovials • Estimate volume and add DMSO to a final concentration of 10% (see table) • Cap cryovials and mix gently by inverting several times • Freeze at – 20° C (-4°F) for 1 day • Store at – 80° C (-112°F)until shipping

  15. Lab Manual p 18 Speckled Blue/Black Top Tube

  16. Speckled Red/Green Top Lab Manual p 12, 19 Using the already processed Red/Green top tubes: • Pull out the white cell layer from both Red Green Top tubes • Add to one new 15 ml centrifuge tube • Add PBS to the conical tube to bring total volume to 15 ml • Cap tube and mix by inverting several times • Centrifuge for 15 minutes at 600 RCF • Aspirate and discard supernatant without disturbing cell pellet • Add PBS to the conical tube to bring total volume to 10 ml • Cap tube and mix by inverting several times • Centrifuge for 15 minutes at 600 RCF • Aspirate and discard supernatant without disturbing cell pellet • Freeze cell pellet at -80º C (-112°F)until shipping

  17. Lab Manual p 19 Speckled Red/Green Top Tubes

  18. PAXGENE DNA Tube Lab Manual p 12, 20 • Place tube upright in wire rack • Freeze at - 20º C (-4º F)for 24 hrs NOTE: Do not freeze in styrofoam, tube will crack • After 24 hours, transfer to -80º C (-112°F)freezer • Maintain at -80ºC (-112°F)until shipping

  19. Lab Manual p 13, 21 Lab Sample Log • Complete One log per patient, add: • Affix cryovial labels with Patient ID# to Lab Sample • Log in space provided • Date blood samples taken for each draw • # each cryovial/tube processed per day by colour • Total # samples processed per day Date sample taken on label = date recorded on eCRF worksheet!

  20. Lab Manual p 15 Packaging & Shipping • Each patient: place following in smaller individual blood draw boxes (total of 4 blood draw boxes per patient) • Cryovials • DNA tube • PBMC 15mL centrifuge tube • Place smaller boxes securely in a larger shipping box • Add dry ice • Add completed Lab Sample Logs (one log per patient) • Ship via FedEx within 8 weeks of collection to Colorado (Mon-Wed) • Indicate “Bill Recipient” on the FedEx shipping label Check local courier services for schedule

  21. Packaging & Shipping Important Considerations • Please be sure to inquire about your local service schedules and the latest time of day that you can call to arrange for a pick-up • Local courier service (pickup and delivery) may be limited prior to, during and following observed holidays. It is imperative that you check local service schedules in advance of the holiday. • Specimens should be shipped from Mondays through Wednesdays only.
