  • Slide 24 : Septic Shock Is Unique —Signs of Septic Shock Differ From Hypovolemic and Cardiogenic Shock In septic shock the patient’s calculated cardiac output may be normal, increased, or decreased. In hypovolemic and cardiogenic shock, cardiac output is redistributed (diverted away from the skin, intestines, and kidneys) to maintain flow to the brain and heart. In septic shock blood flow is maldistributed so that some tissue beds (typically including the skin) receive excellent blood flow whereas others receive inadequate blood flow. Hypotension may be present despite skin perfusion that appears to be good. Early signs of septic shock include fever or hypothermia plus tachy-cardia and tachypnea. The number of white blood cells may be increased (leukocytosis) or severely decreased (leukopenia), and the number of immature (band) forms of white blood cells is increased.

  • 2. NAAMA experience
    • By
    • Yasser Elborai , MD
    • Assisstent Lecturer of Pediatric Oncology
    • NCI – Cairo University
  • 3.
    • NAAMA “National Arab American Medical Association” is a Non Governmental Organization (NGO) composed of an Arabian doctors living in America
    • They are trying to help doctors in Egypt and other Arabian countries by different ways like offering training courses and research work
  • 4.
    • Due to collaboration between National Cancer Institute (NCI) – Egypt and National Arab American Medical Association (NAAMA) – USA, there was a 3 months training course for Pediatric Intensive Care Unit (PICU)
    • This training course was in DeVos children’s hospital – Michigan – USA
  • 5. Pediatric Intensive Care Unit (PICU)
    • What is the aim of building PICU ?
    • How do you construct PICU ?
    • How do you manage PICU ?
  • 6. What is the aim of building PICU ?
    • To give our critically ill patients a proper treatment
    • To create a new subspecialty in our pediatric department
    • To decrease the load of work on main ICU in our institute

    All types of syringes, lines, tubes, masks,…
    • Aeration
    Air conditioned Air conditioned
  • 10.
    • The bed is in the center of the room to be accessible from all sides that facilitate the work
    • The bed is only accessible from 3 sides as usual

    • Character of
    • walls and floor
    The walls and floors are washable and can be easily cleaned by anti septic measures
  • 11. How do you manage PICU ?
    • Criteria of admission
    • Nursing notes
    • Doctor’s notes
    • Multidisciplinary team to deal with the patient
    • Computer based system
    • Ratio between nurses and patients
    • Criteria of discharge
  • 12.
    • Criteria of admission:
    • There are many indications for PICU admission but the most common cause here in our institute will be shock specially septic shock
    • ► if the patient is hemodynamically unstable:
    • - Heart rate greater than:
        • 90 beats per minute at the age of puberty or more.
        • 110 beats per minute at the age of 10 years.
        • 120 beats per minute at the age of 4 years or less.
  • 13.
    • - Systolic arterial pressure lower than:
        • 90 mm Hg at the age of puberty or more.
        • 70 mm Hg at the age of 10 years.
        • 50 mm Hg at the age of 4 years or less.
    • for at least 30 minutes despite adequate fluid replacement and more than 5 µg/kg of body weight of dopamine or current treatment with epinephrine or norepinephrine.
    • Urinary output of less than 0.5 mL/kg of body weight for at least 1 hour
    • Arterial lactate levels higher than 2 mmol/L
  • 14. Stages of shock
    • 1- Early shock : tachycardia, poor capillary perfusion
    • cold extremities, but in septic shock may be worm extremities because ischemia of precapillary sphincter
    • 2- Established shock : clinical triad tachycardia, hypotension, peripheral hypoperfusion will be evident. The patient looks pale and anxious
  • 15.
    • 3- Advanced shock : the blood flow will increase to more vital organs (brain, heart) at the expenses of the less vital organs (kidneys, lungs, GIT)
    • kidneys: acute renal failure (oliguria, metabolic acidosis)
    • Lungs : Adult Respiratory Distress Syndrome (ARDS)
    • GIT : Ischemia, stress ulcer, hemorrhage, ileus
    • Blood : Disseminated Intravascular Coagulation (DIC)
    • Metabolic: metabolic acidosis, electrolytes disturbance
    • Brain : Hypoxic ischemic encephalopathy
    • Heart : Myocardial ischemia, arrhythmia
  • 16.
    • 4- Irreversible shock : irreversible cellular damage (mitochondria, cell membrane) clinically, serious arrhythmia, deep coma, pH below 7.0 in spite of vigorous correction with sodium bicarbonate
    • So, our role is how to detect this hemodynamically unstable patient in his early stage of shock to give him the best supportive treatment and careful observation to get a better out come
  • 17. Septic Shock SIRS/Sepsis/Septic shock Mediator release: exogenous & endogenous Maldistribution of blood flow Cardiac dysfunction Imbalance of oxygen supply and demand Alterations in metabolism Outcomes of mediator release in systemic inflammatory response syndrome (SIRS), sepsis, and septic shock
  • 18. Septic Shock Is Unique
    • Cardiac output may be normal, increased, or decreased.
    • Hypotension and poor end-organ perfusion may be present despite “good” skin perfusion. Hypotension is still a sign of decompensation .
    • Early signs of sepsis/septic shock include
      • Fever or hypothermia
      • Tachycardia and tachypnea
      • Leukocytosis, leukopenia, or increased bands
  • 19. Septic Shock: “Warm Shock”
    • Early, compensated, hyperdynamic state
    • Clinical signs
      • Warm extremities with bounding pulses, tachycardia, tachypnea, confusion.
    • Physiologic parameters
      • widened pulse pressure, increased cardiac output and mixed venous saturation, decreased systemic vascular resistance.
    • Biochemical evidence:
      • Hypocarbia, elevated lactate, hyperglycemia
  • 20.
    • Late, uncompensated stage with drop in cardiac output.
    • Clinical signs
      • Cyanosis, cold and clammy skin, rapid, thready pulses, shallow respirations.
    • Physiologic parameters
      • Decreased mixed venous sats, cardiac output and CVP, increased SVR, thrombocytopenia, oliguria, myocardial dysfunction, capillary leak
    • Biochemical abnormalities
      • Metabolic acidosis, hypoxia, coagulopathy, hypoglycemia.
    Septic Shock: “Cold Shock”
  • 21. Septic Shock (con’t)
    • Cold Shock rapidly progresses to MOSF or death, if untreated
    • Multi-Organ System Failure: Coma, ARDS, CHF, Renal Failure, Ileus, hemorrhage, DIC
    • More organ systems involved, worse the prognosis
    • Therapy: ABCs, fluid
    • Appropriate antibiotics, treatment of underlying cause
  • 22.
    • Nursing notes:
    • the nurse should take a brief history about the patient’s illness and his previous vital signs
    • Doctor’s notes:
    • The doctor should take a full detailed history about the present and past illness and medications
    • Multidisciplinary team to deal with the patient:
    • Interactions between other department e.g. surgery, radiotherapy, radio diagnosis, and clinical pathology is extremely essential for the sake of the patient
  • 23.
    • Computer based system:
    • If the system is computer based that will facilitate detection of any deterioration of the patients’ clinical condition through the curves drawn temperature, blood pressures, urine output,……..
    • Ratio between nurses and patients:
    • nurse to patient ration should be 1:1 or at least 1:2
    • Criteria of discharge:
    • If the patient is hemodinamically stable for at least 24 h, he can transferred to normal floor to continue his treatment
  • 24. Conclusions
  • 25. We are trying to create a new pediatric care unit similar to that we observed in DeVos children’s hospital-Michigan-USA But as an initial step it will be a pediatric intermediate care unit and in the near future it will be a pediatric intensive care unit
