Comprehensive Patient Management in the Case of Forearm Extravasation

QUESTION

A 60-year-old female with PMH of HTN, HLD, DM, and Hypothyroidism was admitted due to non-exertional chest pain. The patient underwent Coronary CT Angiography. The patient developed right forearm extravasation when the IV contrast was administered. You are the 1st call provider and were notified by the radiologist about the incident.

Answer the following questions:

1. Subjective
   • What pertinent information would you ask the radiologist?
   • What pertinent information would you ask the patient?
2. Objective:
   • What would be the focus of your assessment?
   • What tests or procedures (Lab or Diagnostic) would you perform or order for this patient?
3. Diagnosis:
   • What are the top 3 differential diagnoses you would consider for this patient, and what is your rationale?
   • You ordered to measure the Compartment Pressure, and the result was 28 mm Hg. What is your interpretation of the result?
   • What is the final diagnosis?
   • If the total CK result was 16,000 would you consider other diagnoses and plan of care? Discuss your rationale.
4. Plan:
   • What is the gold standard treatment for the patient’s final diagnosis?
   • When would you consider consulting other services? Discuss your rationale.
   • What is your disposition? Admit vs. Discharge? Why?

ANSWER

Comprehensive Patient Management in the Case of Forearm Extravasation

The scenario of a 60-year-old female with a complex medical history, presenting with non-exertional chest pain and subsequently developing right forearm extravasation during Coronary CT Angiography, demands a thorough and systematic approach to patient management. As the 1st call provider, addressing the incident and ensuring appropriate care is essential. This essay outlines the key steps in the subjective, objective, diagnosis, and plan phases of patient management, optimizing both patient safety and outcome.

Subjective Assessment: Communication and Patient-Centered Inquiry

Upon notification by the radiologist, communication with them is pivotal to understand the details of the extravasation incident. Pertinent inquiries include the volume and type of contrast agent extravasated, the time elapsed since extravasation, and any associated symptoms or signs of complication.

Simultaneously, engaging the patient in a comprehensive history-taking is imperative. Inquiry into the patient’s pain perception, nature, location, and radiation of chest pain is essential. Gathering information on the onset, duration, and alleviating/exacerbating factors helps determine the severity and potential cardiac involvement.

Objective Assessment: Focused Examination and Diagnostic Strategies

The objective assessment should concentrate on the patient’s cardiovascular and neurovascular status. A thorough examination of the right forearm, assessing for any signs of compartment syndrome, impaired circulation, or sensory/motor deficits, is crucial. Palpation, capillary refill, and comparison with the unaffected limb guide this evaluation.

Diagnostic strategies entail prompt laboratory and imaging studies. Given the patient’s history, assessing cardiac biomarkers (e.g., troponin) aids in evaluating potential myocardial ischemia. Additionally, complete blood count and basic metabolic panel provide a broader health overview.

Diagnosis and Differential Diagnoses: Informed Decision-Making

The top three differential diagnoses to consider include acute coronary syndrome, nerve or vascular injury from extravasation, and compartment syndrome. Acute coronary syndrome is relevant due to the patient’s chest pain history and risk factors. Extravasation-associated injuries could cause neurological or vascular impairment. Compartment syndrome warrants consideration due to elevated compartment pressures.

An elevated compartment pressure of 28 mm Hg suggests the possibility of compartment syndrome, necessitating urgent intervention to prevent tissue damage.

The final diagnosis, considering the patient’s history, exam findings, and elevated CK levels, is compartment syndrome secondary to forearm extravasation.

Plan: A Multidisciplinary Approach

Gold standard treatment for compartment syndrome involves immediate surgical intervention to decompress the affected compartment. Prompt consultation with a surgeon is paramount for emergent evaluation and intervention.

Consultation with vascular surgery, plastic surgery, and orthopedics may be warranted to address potential complications and plan subsequent care.

In terms of disposition, admission is indicated for the patient’s safety and close monitoring. Compartment syndrome can lead to irreversible tissue damage and disability if not managed promptly.

In conclusion, effective patient management in cases like forearm extravasation requires a comprehensive approach encompassing thorough assessment, diagnostic strategies, and prompt intervention. Collaboration with various specialties ensures patient safety and optimal outcomes, aligning with the principles of patient-centered care and evidence-based practice.
