Patient Assessment/Management Flashcards

1
Q

In the setting of cardiac arrest, the approach of ABCDE changes to what? (2)

A
  • “the CABs”: chest compressions, airway, and breathing
  • CAB can also be applied in massive trauma situations, in the setting of massive blood loss to treat hypovolemic shock

Q

Describe: Airway management (14)

A
    1. Basic Airway Management
      * protect the C-spine
      * head-tilt (if C-spine injury not suspected) or jaw thrust to open the airway
      * sweep and suction to clear mouth of foreign material
    1. Temporizing Measures
      * nasopharyngeal airway (if gag reflex present, i.e.conscious)
      * oropharyngeal airway (if gag reflex absent, i.e. unconscious)
      * “rescue” airway devices (e.g. laryngeal mask airway, Combitube®)
      * transtracheal jet ventilation through cricothyroid membrane (last resort)
    1. Definitive Airway Management
      * ETT intubation within-line stabilization of C-spine
      * orotracheal ± RSI preferred
      * nasotracheal may be better tolerated in conscious patient
      * relatively contraindicated with basal skull fracture
      * does not provide 100% protection against aspiration
      * surgical airway (if unable to intubate using oral/nasal route and unable to ventilate)
      * cricothyroidotomy

19
Q

Describe: Management of Hemorrhagic Shock (6)

A
  • clear airway and assess breathing either first or simultaneously
  • apply direct pressure on external wounds while elevating extremities. Do not remove impaled objects in the emergency room setting as they may tamponade bleeds

  • if continual bleeding or no response to crystalloids, considerp RBC transfusion, ideally crossmatched.
  • If crossmatched blood is unavailable, consider O- for women of childbearing age and O+ for men. Use FFP, platelets or tranexamic acid in early bleeding consider common sites of internal bleeding (abdomen, chest, pelvis, long bones) where surgical intervention may be necessary

Q

Describe ethical considerations with: Jehovah’s Witnesses (7)

A
  • Capable adults have the right to refuse medical treatment
  • May refuse whole blood, pRBCs, platelets, and plasma even if life-saving
  • Should be questioned directly about the use of albumin, immunoglobulins, hemophilic preparations
  • Do not allow autologous transfusion unless there is uninterrupted extra corporeal circulation
  • Usually ask for the highest possible quality of care without the use of the above interventions (e.g. crystalloids for volume expansion, attempts at bloodless surgery)
  • Patient will generally sign hospital forms releasing medical staff from liability
  • Most legal cases involve children of Jehovah’s Witnesses; if life-saving treatment is refused, contact CAS
