General

  • ACLS
    • General
      • Capnography (measurement of partial pressure of CO2 in the exhales breath over time)
  • End-tidal CO2
    • Typically gradually rises with high-quality CPR
      • Increase in CO w/ROSC will show a sudden rise in EtCO2 on capnography (Ex. 16 to 38) and is the earliest indicator of ROSC, even before a pulse is palpated
      • EtCO2 of ≤10 mmHg after 20 minutes of CPR are highly unlikely to achieve ROSC
  • Anemia
    • IRONMAN: IV Iron not better than placebo did not change RBC transfusion during ICU stay
  • Illness Severity Assessment
    • qSOFA
    • APACHE IV
    • SAPs
  • Disease Specific Scoring Systems
    • CURB65
    • sPESI (Pulmonary Embolism Severity Index)
    • PSI
  • ICU Delirium
    • Mobilize pt, remove catheters, provide visual and hearing aids
  • ICU Toxicology
  • Oncologic Emergencies in the ICU
  • Palliative Care in the ICU

ICU-Acquired Weakness

  • Evaluation
    • Medical Research Council Muscle Scale (MRCMS) is a bedside tool used to evaluate weakness
  • Critical Illness Myopathy
    • RF: Steroids, Neuromuscular blocking agents, Sepsis
    • Features
      • Flaccid limbs
      • Facial and respiratory weakness
      • Normal sensation
    • Normal to mild CK elevation (<2000)
  • Critical Illness Polyneuropathy
    • RF: Sepsis
    • Features
      • Flaccid limbs
      • Respiratory weakness
      • Distal sensory loss
    • Normal CK
  • Rhabdomyolysis
    • RF: Infection, Medications, Serotonin Syndrome, Neuroleptic Malignant Syndrome
    • Features
      • Mild to moderate limb weakness
      • Muscle swelling
      • Myalgias
      • DTRs intact
    • Marked CK elevation (>5000)
  • Guillain-Barre Syndrome
    • RF: Infection
    • Features
      • Progressive and symmetric
    • Normal CK
  • Prolonged Neuromuscular Blockade
    • RF: Prolonged paralytic agent use (days), often in renal or hepatic insufficiency
    • Features
      • Flaccid limbs
      • Respiratory weakness
      • Transient improvement after anticholinesterase
    • Normal CK

Hypothermia

  • Symptoms
    • Shivering, but as hypothermia progresses, shivering stops
    • Moderate: Bradycardia, hypoventilation, lethargy, atrial arrhythmias, decreased shivering
    • Severe: absent reflexes, ventricular arrhythmia, asystole, and apnea
  • Diagnosis: Temperature
    • Monitoring: Esophageal temperature probe
      • Rectal and bladder temperatures will lag the rising core temperature during the rewarming process.
  • Treatment
    • Mild (> 35.0 °C (95.0 °F))
      • Passive external warming
    • Moderate (28.0 - 35.0 °C (82.4 - 95.0 °F)) or (<28.0 °C (82.4 °F)) w/o coma or CV collapse
      • 1) Active external warming
        • Warming blankets and forced warm air, heating pads
      • 2) Active internal warming
    • Severe (<28.0 °C (82.4 °F)) in the setting of coma or cardiovascular collapse
      • Cardiac Arrest: Extracorporeal support, including cardiopulmonary bypass, VA ECMO
      • No Cardiac Arrest: Active internal rewarming (107F fluid)
        • Infusion of heated intravenous crystalloid solution as well as lavage of the peritoneal or pleural cavities irrigation
    • Other (Acid-Base Disturbances): HD

Heat Stroke

  • Strenuous activity during hot and humid weather
    • Dehydration, poor acclimatization, lack of fitness
  • Hyperthermia
  • Core temp >104F (40C) immediately after collapse plus:
    • CNS dysfunction: AMS, confusion, irritability, seizure
    • Additional organ failure: DIC, Renal/Hepatic failure, ARDS
  • Monitoring
    • Rectal or esophageal probes
  • Prognosis:
    • 20-60% mortality
  • Treatment
    • Fluid resuscitation, electrolyte correction
    • No antipyretic therapy
    • Exertional: Ice water immersion
    • Non-Exertional: Evaporative cooling (lukewarm water with fans), high-flow cool water dousing, ice/wet towel rotation, cold shower
      • Ice Water immersion has increased mortality in elderly w/Non-Exertional Heat Stroke
