Name of the Procedure:

High Osmolar Contrast Material, 300-349 mg/ml Iodine Concentration, per ml
Common name(s): Iodinated Contrast Injection
Medical Term: Q9962

Summary

This procedure involves injecting a high osmolar contrast material containing iodine into the body to enhance the visibility of internal organs and structures during radiological imaging tests such as X-rays, CT scans, and angiograms.

Purpose

The procedure helps in diagnosing medical conditions by improving the clarity and contrast of images taken of the body's internal structures. The goal is to provide detailed visual information that can assist in identifying abnormalities, such as tumors, blood vessel issues, or organ dysfunctions.

Indications

• Suspicion of blockages or abnormalities in blood vessels
• Diagnosis of tumors or growths
• Assessment of organ function and structure
• Detailed imaging required for surgical planning

Preparation

• Fasting for at least 4-6 hours prior to the procedure
• Hydration encouraged up to the time of the procedure unless otherwise instructed
• Review of current medications and possible adjustments
• Allergy screening, especially for iodine or shellfish
• Pre-procedure blood tests to assess kidney function

Procedure Description

1. Patient is positioned on a movable table.
2. An intravenous (IV) line is inserted into a vein, usually in the arm.
3. The high osmolar contrast material (Q9962) is injected through the IV line.
4. Imaging tests like X-rays, CT scans, or angiograms are performed while the contrast material enhances the images.
5. The procedure may involve multiple positions or scans to ensure comprehensive imaging.

Tools/Equipment:

• IV catheter
• Contrast dye (Q9962)
• Imaging equipment (X-ray, CT scanner, etc.)

Anesthesia: Generally, no anesthesia required unless part of a broader procedure.

Duration

The injection and imaging process typically takes between 30 to 60 minutes, depending on the complexity and the number of images required.

Setting

The procedure is usually performed in a hospital, outpatient radiology clinic, or surgical center equipped with advanced imaging technology.

Personnel

• Radiologist or Interventional Radiologist
• Radiologic Technologist
• Nursing staff for IV insertion and monitoring

Risks and Complications

Common Risks:

• Mild allergic reactions (itching, rash)
• Mild nausea or vomiting

Rare Risks:

• Severe allergic reactions (anaphylaxis)
• Kidney damage, especially in patients with pre-existing kidney conditions
• Flushing or warm sensation throughout the body

Complication Management: Emergency medications and interventions available on-site for severe reactions; close monitoring of kidney function post-procedure.

Benefits

• Improved diagnostic accuracy
• Visualization of internal structures and abnormalities that are not otherwise detectable
• Critical information for planning treatments or surgeries
• Results available within a few hours to a day

Recovery

• Monitoring for adverse reactions immediately post-procedure
• Increased fluid intake to help flush contrast material out of the body
• Usually, patients can resume normal activities within a few hours if no complications
• Follow-up appointments if further diagnostic evaluation is needed

Alternatives

• Magnetic Resonance Imaging (MRI) without contrast
• Ultrasound imaging
• Non-contrast CT scans

Pros and Cons:

• MRI avoids iodine but may not provide sufficient detail for some conditions
• Ultrasound is non-invasive but less detailed for certain structures
• Non-contrast imaging might miss subtle abnormalities that contrast-enhanced studies would reveal

Patient Experience

During:

• Mild discomfort from IV insertion
• Sensation of warmth or flushing during contrast injection
• Possible metallic taste in the mouth

After:

• May experience mild discomfort at IV site
• Advised to drink plenty of water to aid in contrast elimination
• Mild fatigue possible but usually resolves quickly

Pain Management:

• Comfort measures taken during IV insertion, such as local anesthetic if needed
• Post-procedure hydration encouraged for comfort and health
