Read the first 7 Emergency Response Procedures flashcards as text

  1. A patient develops sudden severe chest pain and diaphoresis during a foot and ankle procedure under local anesthesia. What is the FIRST priority action?

    Answer: Stop the procedure and activate the emergency response system

    Stopping the procedure and activating emergency services is the first priority to ensure timely advanced care for a potential myocardial infarction.

  2. Which vasopressor is the FIRST-LINE agent for anaphylactic shock in the surgical setting?

    Answer: Epinephrine 0.3-0.5 mg IM (1:1,000 solution)

    Epinephrine 1:1,000 solution given intramuscularly is the first-line treatment for anaphylaxis due to its rapid alpha and beta adrenergic effects.

  3. During a foot procedure, a patient on warfarin develops uncontrolled hemorrhage. In addition to direct pressure, which agent most rapidly reverses warfarin anticoagulation?

    Answer: 4-factor prothrombin complex concentrate (PCC)

    4-factor PCC provides rapid reversal of warfarin by replacing factors II, VII, IX, and X and has faster onset than FFP.

  4. A patient undergoing regional nerve block develops sudden tinnitus, perioral numbness, and confusion. This presentation is most consistent with:

    Answer: Local anesthetic systemic toxicity (LAST)

    Tinnitus, perioral numbness, and CNS excitation followed by depression are classic early signs of local anesthetic systemic toxicity (LAST).

  5. What is the recommended initial treatment for local anesthetic systemic toxicity (LAST) with cardiovascular collapse?

    Answer: 20% lipid emulsion therapy (Intralipid)

    20% lipid emulsion (Intralipid) acts as a 'lipid sink,' sequestering the lipid-soluble local anesthetic and is the specific antidote for LAST.

  6. A patient with diabetes develops a postoperative wound with rapid spreading erythema, crepitus on palpation, and a foul odor. The MOST urgent next step is:

    Answer: Emergent surgical debridement and IV antibiotics

    Crepitus and rapid spreading erythema indicate necrotizing fasciitis, which requires emergent wide surgical debridement as delays dramatically increase mortality.

  7. During a foot surgery, a tourniquet has been inflated for 90 minutes. Upon deflation, the patient develops hypotension and bradycardia. This presentation is most likely caused by:

    Answer: Tourniquet reperfusion syndrome releasing vasodilatory mediators

    Tourniquet reperfusion syndrome occurs when ischemic metabolites, potassium, and vasodilatory substances are released into systemic circulation upon cuff deflation.
