HISTORY:
CT DOSE:
SEDATION: Monitored by the IR registered nurse or surrogate, an independent trained observer providing Moderate Sedation with fentanyl.
CONSENT: Following discussion procedure its risks benefits (including bleeding and vessel damage) and alternatives, review of readily available relevant imaging prior to the procedure informed consent was obtained witnessed and documented upon the chart. Standard presurgical timeout confirming patient procedure and when relevant side and site was performed. Any discrepancies were resolved via consultation with appropriate readily available data sources. The patient was prepared and draped in standard sterile fashion.
TECHNIQUE:
Following the careful explanation of the potential risks and benefits of the procedure, oral and written informed consent was obtained.
Procedure was done under sterile technique and local anesthesia using 1 % lidocaine.
The target pericardial fluid was localized using CT.
Anterior parasternal approach was used to guide a micropuncture needle into the pericardial effusion toward the left side. A microwire was inserted which was subsequently upsized to an 035 wire, after confirmation of its position. Finally an 8 French non-locking drain was placed and position confirmed with CT.
Approximately ** cc of bloody fluid was aspirated and drain was attached to a bag. Samples were sent to lab for analysis.
The patient tolerated the procedure well. There were no immediate complications.
IMPRESSION:
Successful CT guided pericardial drain placement.
Frequently Asked Questions
What is a CT guided pericardial drain placement?
A CT guided pericardial drain placement is a medical procedure used to remove excess fluid from the pericardial space, the area around the heart. It is performed under CT (computed tomography) imaging guidance to ensure precise needle placement. This technique helps relieve symptoms and diagnose the cause of fluid accumulation, known as pericardial effusion.
Why is sedation used during a pericardial drain placement?
Sedation is used during a pericardial drain placement to help the patient remain comfortable and calm throughout the procedure. Moderate sedation, often with drugs like fentanyl, is typically administered by a trained observer. It ensures the patient experiences minimal discomfort while still being able to respond to verbal cues if necessary.
How is consent obtained for a CT guided pericardial drain procedure?
Informed consent for a CT guided pericardial drain procedure is obtained by discussing the risks, benefits, and alternatives with the patient. This includes potential complications like bleeding or vessel damage. After reviewing relevant imaging and ensuring the patient understands the procedure, written consent is documented in the medical chart.
What is the purpose of using CT imaging in this procedure?
CT imaging is used in pericardial drain placement to provide detailed cross-sectional images of the heart and surrounding areas. It guides the physician in accurately locating the pericardial effusion and ensures the safe insertion of the drainage needle and catheter, minimizing risks of injury to nearby structures.
What are the potential risks of a CT guided pericardial drain placement?
Potential risks of a CT guided pericardial drain placement include bleeding, infection, damage to nearby organs or vessels, and reactions to sedation. However, these risks are minimized by using sterile techniques, precise imaging guidance, and careful patient monitoring during the procedure.
How is the fluid sample from a pericardial drain analyzed?
Fluid aspirated during a pericardial drain placement is sent to a laboratory for analysis. This can include tests to identify infections, cancer cells, or inflammatory conditions. Analyzing the fluid helps in diagnosing the underlying cause of the pericardial effusion and guiding further treatment.
What preparation is required for a CT guided pericardial drain placement?
Preparation for a CT guided pericardial drain placement involves obtaining informed consent, reviewing imaging studies, and confirming patient details in a presurgical timeout. The patient is then positioned and draped in a sterile fashion to prevent infection, and local anesthesia is administered to the procedure site.
What does the term ‘micropuncture needle’ refer to in this procedure?
A micropuncture needle is a small, fine needle used to initially pierce the pericardial space during drain placement. Its use minimizes tissue trauma and allows for the safe introduction of a guidewire, which is then used to direct larger instruments needed for drainage.
Can there be complications after a pericardial drain placement?
While complications are rare with CT guided pericardial drain placement, they can include bleeding, infection, or injury to the heart or surrounding structures. However, the use of sterile techniques, precise imaging, and careful monitoring significantly reduce the likelihood of such complications.
