  3. Hemorrhage / transfusion • Loss of 1.5 mL of blood/KG/min. for 20 mins. • Loss of 150 mL of blood/min. within 1 hr. • Transfusion of 50 % of circulating blood volume within 3 hrs. • Transfusion of one volume of circulating blood within 24 hrs.

  7. Basics for fluids tranfusion after the trauma O2flow = [CO X Hgb X SaO2 X k] + [CO X PaOa x 0.003] • The quickest possible restoration of tissue oxygenation. • Causing the smallest possible biochemical abnormalities. • Protection of renal functions. • Avoiding fluids transfusion-related complications.

  10. On-site strategy of handling the injured Basic life-saving actions Spine immobilization. Fractures immobilization. Dressing external hemorrhage. Bag mask ventilation. • Scoop and run. • Stay and play (stay and treat). Advanced life-saving actions Final securing of the airways. Decompression of pneumothorax. Coniotomy/ tracheotomy. IV access and fluids transfusion. Berlot G, Bacer B, Gullo: Controversial aspects of the prehospital trauma care. Crit Care Clin 2006; 22: 457-468.

  11. On-site actionsScoop and run, or Stay and play? In certain situations, starting rescue actions on site may prolong the time of definite life-saving actions onset1,2,3: • Attempts of artificial airways – instead of bag mask ventilation and transportation to the hospital. • Worse (adverse) result of therapy (next to statistically more frequent occurrence of coagulopathy and multiorgan failure) with the patients who were secured with vascular angioaccess and fluids transfusion and who: • Were diagnosed with penetrating bodily trauma4,5. • Were not secured as far as the hemorrhage site is concerned6.

  12. On-siteactionsScoop and run, orStay and play? With the patients: • With no possibility of final (temporary) hemorrhage securing1,2,3: • Ectopic pregnancy. • Placenta previa. • Premature placental disruption. • Penetrating injuries (vascular injuries in 90%)4. • Internal hemorrhage. • In urban conditions. • In the circumstances when the ETA to the hospital is relatively short (4-12 mins.)5,6. No attempts to cannulate the vessel or fluids transfusion should be made; instead: • The patient should be transported to the hospital a.s.a.p. • The hospital should be informed about the necessity to prepare the operating room and the surgical team (surgeons and anesthesiologist).

With the patients with no possibility of final (temporary) hemorrhage securing1,2,3 no attempts to cannulate the vessel or fluids transfusion should be made, instead: • The patient should be transported to the hospital a.s.a.p.. • The hospital should be informed about the necessity to prepare the operating room and the surgical team (surgeons and anesthesiologist). Adverse effects of fluids transfusion with the lack of securing the hemorrhage site: • Increased bleeding from damaged vessels. • Smaller clot-forming abilities in the site where the vessels are damaged. • Increase in the hematocrit and the hemoglobin levels. • Lowering of the clotting factors levels. • Risk of hypothermia.

  15. On-siteactionsScoop and run, orStay and play? With the patients whose hemorrhage was temporarily secured, e.g. by applying:1,2,: • Pressure dressing. • Tourniquet. • Polymer dressing (e.g. Quick-Cloth). you should: • Secure two peripheral vascular angioaccess points (14G). • Apply infusion of 0.9% NaCl, or lactatad Ringer’s solution (1000 mL) – if SAP< 90 mm Hg (or 110 mm Hg – cerebral injuries). • Maintain MAP: 40-50 mm Hg. • In acute hypovolemiapathophysiology, decrease in preload prevails – hence, the only purposeful action is intravascular volume replacement. • Catecholamines increase afterload and are not recommended at this stage of shock. • Transport the patient to the hospital. • Inform the hospital about the necessity to prepare the operating room and the surgical team (surgeons and anesthesiologist).

  20. On-siteactionshemorrhagestopped but co-existingshock • HyperHAES because: • Instant increase of arterial blood pressure and cardiac output, with decreased systemic vascular resistance (SVR). • Instant microcirculation flow increase. • Lowering adverse effects of ischemia and reperfusion. • Increase of diuresis resulting from improved organ perfusion. • Increase in survival ratio. Kreimeier i Messmer– experimental and clinicalstudies.

  21. HyperHAES • HyperHAES→ 6% HAES (200/ 0.5) + 7,2% NaCl → 250 mL bags. • Na+ 1232 mmol/ L. • Cl- 1232 mmol/ L. • pH 3.5 – 6.0. • Osmolarity: 2464 mOsm/ L. • COP 36 mm Hg. • Dosage: 4 mL/ KG (approx. 250 mL). • Infusion volume: 2 – 5 minutes. …

  22. HyperHAES - effects • Hypertonic solution of NaCl quickly increases circulating blood volume through transferring the fluid from extravascular to intravascular space. • 7.2% NaCl included in the HyperHAES solution is responsible for inducing the mechanism of quick endogenous fluid transfer. • Colloid present in the solution binds water which ensures long-lasting volume effect. • Endogenous water is mobilized mainly from the area of erythrocytes and vascular endothelial cells: • Circulating blood volume is rapidly increased (3 – 4x of the transfused volume). • Microcirculation flow appears through endothelial cells dehydration thus increasing oxygen supply to tissues. …

  23. Ideal solution for fluid resuscitation: • Transfusion of small volume improves perfusion. • Beneficial effect on oxygen extraction in tissues: • Oxygen supply. • Oxygen use. • Proper composition taking into account pH measure and electrolyte composition. • Sterility. • Suitably long effects. • Stability. • Ready to use. • Inexpensive. …

  27. Time to start fluid therapy • Pre-hospital. • Hospital emergency ward. • During emergency operations. • In ICU. Smith JP, Bodai BI, Hill AS i wsp.: Prehosoitalstabilization of criticallyinjuredpatients: a failedconcept. J Trauma 1985; 25: 65-70.

  28. Hospitalactivities Stop the bleeding – great ‘five’ of hemorrhages: • External: • Clinical examination. • BP monitoring. • Chest: • Clinical examination and chest X-ray. • Pulmonary drainage. • Abdomen: • Clinical examination. • DPO, FAST, CT, laparoscopy, laparotomy. • Pelvis: • Clinical examination. • X-ray, CT, angiography. • Long bones. Recognize the shock paying attention to possible problems: • Co-existing CNS injury. • Age. • Body build (athletic). • Medication taken. • Hypothermia. • Pacer. • Clothes (waterproof; Velcro).

InjuryInt J CareInjured 2009; 40S4: 23-26.

  29. Hospital activities US Army • Rescue actions depending on response to fluid resuscitation (to fast transfusion): • 2000 mL of lactated Ringer’s solution (adults). • 20 mL/KG of lactated Ringer’s solution (children). Wilson WC, Grande CM, Hoyt DB w: Trauma. Emergencyresuscitation. Perioperativeanesthesia. Surgical Management. InformaHeathcare USA. 2007.

  30. Purpose of fluid therapy US Army Concerns exclusively young and healthy people without co-existing CNS injury. Early resuscitations ends with final securing of the hemorrhage spot. Wilson WC, Grande CM, Hoyt DB w: Trauma. Emergencyresuscitation. Perioperativeanesthesia. Surgical Management. InformaHeathcare USA. 2007.

  31. DIC andACoTScriteria1,2 • Coagulopathy (on-site/ in the hospital)4,5,6: • Acute coagulopathy of traumatic stress (ACoTS). • Disseminated intravascular coagulation (DIC). • Platelet count: • <50 000 2 pts. • 50 – 100 000 1 pt. • Fibrinogen: • < 1g/L 1 pt. • D-dimers: • > 4 mg/L 3 pts. • 0.39-4 mg/L 2 pts. • INR: • >2,3 2 pts. • 1.4-2.3 1 pts. • Criteria for diagnosing DIC: • ≥ 5 pts. • Criteria for diagnosing acute coagulopathy of traumatic stress (ACoTS): • APTT or/and INR: • >35 secs.or 1.2.

  32. Whyisthediscussionabout DIC and ACoTS so important? 1,2,3 Because coagulation disorders appear as a result of: • Hemorrhage. • Traumatic stress. And are worsened: • Resulting from physical status (co-existing illnesses). • After infusion of 2000 mL of fluids. • And are further increased in the course of: • Hypoperfusionwithall its consequences. • Hypothermia. • Acidosis. • Hypercatecholaminemia. • Electrolyte imbalance.
