PROCEDURES PERFORMED: CT-guided aspiration of abscess
CLINICAL HISTORY:
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.
DESCRIPTION OF PROCEDURE: After obtaining informed consent, the patient was prepped and draped in the usual sterile manner in position on the CT table. The CT images were then used to mark the puncture site in the . After applying local anesthesia a 22-gauge 10 cm Chiba needle was advanced into the fluid collection and samples were drawn off. The fluid sample was sent to the laboratory for culture analysis and cytology. The patient tolerated the procedure and sedation without any immediate complications.
FINDINGS: Small loculated fluid collection within the
IMPRESSION:
Successful CT-guided aspiration of abdominal wall abscess.
Frequently Asked Questions
What is CT-guided aspiration of an abscess?
CT-guided aspiration of an abscess is a medical procedure where a needle is inserted into an abscess to remove pus or fluid, guided by CT imaging. This helps in accurately locating the abscess, ensuring minimal damage to surrounding tissues. The procedure is often used to relieve symptoms and obtain samples for laboratory analysis.
How is sedation managed during a CT-guided aspiration?
During a CT-guided aspiration, sedation is usually managed by a registered nurse or an independent observer who administers moderate sedation, often with medications like fentanyl. This ensures the patient remains comfortable and relaxed, while still being conscious enough to respond to instructions during the procedure.
What are the risks of CT-guided abscess aspiration?
Risks associated with CT-guided abscess aspiration include bleeding, infection, and potential damage to nearby blood vessels or organs. However, these risks are minimized by using CT imaging for precise needle placement and ensuring sterile techniques. Patients are informed of these risks before giving consent.
Informed consent is crucial because it ensures that the patient fully understands the procedure, its risks, benefits, and available alternatives. This process involves discussing the procedure in detail and confirming the patient's willingness to proceed, which is then documented in their medical records.
What happens to the fluid collected during an abscess aspiration?
The fluid collected during an abscess aspiration is sent to a laboratory for analysis. This includes culture tests to identify any bacteria present and cytology to examine the cells in the fluid. The results help in diagnosing the cause of the abscess and planning appropriate treatment.
How is a patient prepared for a CT-guided aspiration?
Preparation for a CT-guided aspiration involves obtaining informed consent, confirming patient identity and procedure details, and preparing the area with sterile techniques. The patient is positioned on the CT table, and local anesthesia is applied to the puncture site to minimize discomfort during the procedure.
What imaging is used during a CT-guided aspiration?
CT, or computed tomography, imaging is used during a CT-guided aspiration. This imaging technique provides detailed cross-sectional images of the body, allowing precise visualization of the abscess and surrounding structures, which guides the needle placement during aspiration.
