Review Clinical Case

1. Learning: Consent with Surrogate Decision-Makers

Purpose of this Scenario

Obtaining consent from a family member for an incapacitated patient adds layers of complexity. You are not only explaining a procedure but also building a therapeutic alliance with a surrogate who is often overwhelmed, scared, and protective. This simulation tests your ability to establish trust with a family member while clearly justifying a complex ICU-level procedure.

2. Scenario Briefing: Consent for Central Line

Your Objective

Your objective is to obtain informed consent from Emily, the daughter and healthcare proxy of an elderly, non-verbal ICU patient, for the placement of a central venous catheter. You must explain why this is necessary and superior to peripheral IVs, while navigating her emotional distress and suspicion.

Patient Background

Your patient is a 78-year-old woman in the ICU with septic shock. She is intubated and sedated. Her daughter, Emily (40s), is her healthcare proxy and is at the bedside. The patient needs multiple, reliable IV access points for vasopressors and other critical medications, and her peripheral IVs are failing.

Crucial Information: Emily is overwhelmed and feels like her mother is just being hooked up to more and more machines. She is suspicious of "more tubes" and doesn't understand why the small IVs in her mother's arms aren't good enough.

Key Procedural Facts

  • Procedure: Ultrasound-guided placement of a central venous catheter into a large vein (e.g., internal jugular or subclavian).
  • Benefits: Provides reliable, long-term access for administering life-saving medications (like vasopressors) that are too caustic for peripheral veins. Allows for monitoring of central venous pressure.
  • Key Risks: Arterial puncture, pneumothorax (collapsed lung), infection (CLABSI), bleeding, air embolism.
  • Alternatives: Continue trying to place peripheral IVs, which is becoming increasingly difficult and unreliable, potentially leading to delays or interruptions in critical medication delivery.
