Advancements in Volume Resuscitation and Colloids Matthew S. Giuca, MD Assistant Professor of Anesthesiology Stony Brook University Medical School Nassau Anesthesia Associates Department of Anesthesia Winthrop University Hospital
Disclosures& Cavets • No Disclosures or conflicts of interest • Caveats….. • Email: mgiuca@winthrop.org • Grateful and honored
Objectives • Discuss Advancements in Volume Resuscitation management • Explain the definition of a Colloid and discuss risks vs benefits of utilization • Present evidence based expert opinions and journal articles that reflect international standards of care • Discuss methodology and approach to different patient populations • Get to the point quickly so you don’t miss any text messages
Goals of Therapy Select a treatment that ameliorates end organ damage and has a favorable benefit to risk profile Evidence based Cost effective Upholds national and community standards Long track record in complex patient populations
History Of Volume Resuscitation • Prior to 1795 – • 1795 – First human to human blood transfusion? - Philip Syng Physick, an American physician from Philadelphia, not published. • 1827 - Cholera epidemic strikes - Cholera started in India, spread to Russia by 1829 then England in 1831 and the United States by 1832 claiming thousands of lives. • 1829 - First documented blood transfusion - Williams Blundell (1790–1878), an English physician and obstetrician • 1830 - First successful blood transfusion - Blundell successfully transfuses a woman dying of severe postpartum hemorrhage • 1830 - First intravenous use of water - Herman and Jaehnichen, Russians physicians desperate in the face of cholera • 1832 - First saline infusion - Thomas Latta injects 6 pints of a solution of 1⁄2 concentration of soda and subcarbonate soda (58 mEq Na, 49 mEq Cl, 9 mEq HCO3). • 1833 - First successful saline infusion - Latta’s 2nd patient, 330 cm3 of fluid over 12 h and survives. • 1834 - First use of intravenous albumin - John Mackintosh, Scottish physician and student of Latta comments that “it would be advisable to make the fluid resemble as much as possible the serum of blood, by adding albumin obtained from egg”.
History Of Volume Resuscitation • 1849 - Blood transfusions deemed acceptable - Walton, a famous English physician reviewed all transfusions to date and concluded the procedure a success with a mortality rate of 30%. He judged that the quantity of blood transfused should be no less than 6 oz and no more than 16 oz (roughly 1 unit blood). • 1876 - Ringer’s solution introduced - containing 8 g NaCl, 0.3 g KCl and 0.33 g CaCl • 1894 - Citrate introduced as an anticoagulant - Sir Almroth Wright, an English pathologist introduces the use of citrate as an anticoagulant • 1901 - Blood groups identified - Karl Landsteiner of Austria discovered three of the four major blood groups and is awarded the Nobel Prize for his work in 1930. • 1907 - Blood groups identified - Jansky from Chekoslovakia discovers the fourth blood group • 1908 - Blood typing become commercially available • 1932 - First blood bank established – Leningrad, 2 years later the first American blood bank by Bernard Fantus. • 1930 – Rochester plastic needle - In 1950 David Masa, at the Mayo Clinic, introduced the plastic needle, similar to today’s needles.
FDA Safety Communication:Boxed Warning on increased mortality and severe renal injury, and additional warning on risk of bleeding, for use of hydroxyethyl starch solutions in some settings • Date: June 24 2013 • Recommendations for Health Professionals • Do not use HES solutions in critically ill adult patients including those with sepsis, and those admitted to the ICU. Avoid use in patients with pre-existing renal dysfunction. Discontinue use of HES at the first sign of renal injury. Need for renal replacement therapy has been reported up to 90 days after HES administration. Continue to monitor renal function for at least 90 days in all patients. Avoid use in patients undergoing open heart surgery in association with cardiopulmonary bypass due to excess bleeding. Discontinue use of HES at the first sign of coagulopathy.
Surviving Sepsis Campaign: International Guidelines for Management of Severe Sepsis and Septic Shock: 2012 R. Phillip Dellinger, MD; Mitchell M. Levy, MD; Andrew Rhodes, MB BS3 et al.. • Hemodynamic Support and Adjunctive Therapy (Table 6) • G. Fluid Therapy of Severe Sepsis • We recommend crystalloids be used as the initial fluid of choice in the resuscitation of severe sepsis and septic shock (grade 1B). • We recommend against the use of hydroxyethyl starches (HES) for fluid resuscitation of severe sepsis and septic shock (grade 1B). (This recommendation is based on the results of the VISEP [128], CRYSTMAS [122], 6S [123], and CHEST [124] trials. The results of the recently completed CRYSTAL trial were not considered.)
TABLE 8. Recommendations: Other Supportive Therapy of Severe Sepsis K. blood Product Administration • Once tissue hypoperfusion has resolved and in the absence of extenuating circumstances, such as myocardial ischemia, severe hypoxemia, acute hemorrhage, or ischemic heart disease, we recommend that red blood cell transfusion occur only when hemoglobin concentration decreases to <7.0 g/dL to target a hemoglobin concentration of 7.0 –9.0 g/dL in adults (grade 1B). • Not using erythropoietin as a specific treatment of anemia associated with severe sepsis (grade 1B). • Fresh frozen plasma not be used to correct laboratory clotting abnormalities in the absence of bleeding or planned invasive procedures (grade 2D). • Not using antithrombin for the treatment of severe sepsis and septic shock (grade 1B). • In patients with severe sepsis, administer platelets prophylactically when counts are <10,000/mm3 (10 x 109/L) in the absence of apparent bleeding. We suggest prophylactic platelet transfusion when counts are < 20,000/mm3 (20 x 109/L) if the patient has a significant risk of bleeding. Higher platelet counts (≥50,000/mm3 [50 x 109/L]) are advised for active bleeding, surgery, or invasive procedures (grade 2D).
Whether you reach for colloids or crystalloids you still need to have the right measures to guide your volume therapy….
