Anesthesia for closed chest procedures; pneumocentesis

CPT4 code

Name of the Procedure:

Anesthesia for closed chest procedures; pneumocentesis
Common Names: Pneumocentesis, Needle Aspiration of the Lung


Anesthesia for closed chest procedures involves administering medication to eliminate pain and discomfort for patients undergoing a pneumocentesis. Pneumocentesis is a minimally invasive procedure where a needle is used to remove air, fluid, or other substances from the pleural space in the chest cavity.


Medical Condition Addressed: The procedure is used to treat conditions like pneumothorax (collapsed lung), pleural effusion (excess fluid in the pleural space), and other related respiratory issues. Goals/Expected Outcomes: The primary goal is to relieve symptoms such as chest pain and difficulty breathing, improve lung function, and obtain samples for diagnostic purposes.



  • Sudden onset chest pain
  • Shortness of breath
  • Persistent cough
  • Abnormal findings on chest X-rays or CT scans
    Patient Criteria:
  • Presence of pleural effusion or pneumothorax
  • Unresponsive to conservative treatments


Pre-Procedure Instructions:

  • Fasting for 6-8 hours prior, depending on the type of anesthesia used
  • Discontinuation or adjustment of certain medications (e.g., blood thinners)
    Diagnostic Tests:
  • Chest X-rays
  • CT scans
  • Blood tests to assess overall health and coagulation status

Procedure Description

  1. Patient Positioning: The patient is positioned either sitting or lying down.
  2. Anesthesia Administration: Local anesthesia is typically used. For more complex cases, general anesthesia or sedation may be administered by an anesthesiologist.
  3. Needle Insertion: The site of insertion is cleaned and sterilized. A needle is carefully inserted into the pleural space under imaging guidance (e.g., ultrasound or CT).
  4. Aspiration: Air or fluid is drawn out through the needle using a syringe or catheter.
  5. Closure and Dressing: The needle is removed, and the insertion site is bandaged.


  • Needle or catheter
  • Syringe
  • Imaging equipment (ultrasound or CT scanner)


The procedure typically takes 30 minutes to 1 hour.


Pneumocentesis can be performed in a hospital, outpatient clinic, or a surgical center equipped with imaging technology.


  • Anesthesiologist/Nurse Anesthetist
  • Pulmonologist/Surgeon
  • Radiologist (if imaging guidance is used)
  • Nurses and other supporting medical staff

Risks and Complications

Common Risks:

  • Pain or discomfort at the insertion site
  • Minor bleeding
  • Infection
    Rare Risks:
  • Lung collapse (if not already present)
  • Injury to nearby organs
  • Severe bleeding

Management of Complications:

  • Close monitoring and immediate intervention by medical staff
  • Additional procedures to address complications if they arise


Expected Benefits:

  • Immediate relief from symptoms such as chest pain and shortness of breath
  • Improved diagnostic clarity for underlying conditions
    Timeline for Benefits:
  • Benefits are often realized immediately or within a few hours after the procedure.


Post-Procedure Care:

  • Monitoring in a recovery area for a few hours
  • Instructions to avoid strenuous activities for a day or two
    Recovery Time and Restrictions:
  • Most patients recover within 24-48 hours
  • Follow-up appointments to assess the procedure's success and monitor for complications


Other Treatment Options:

  • Thoracentesis (removal of pleural fluid)
  • Chest tube placement
  • Observation and conservative management (e.g., oxygen therapy)
    Pros and Cons:
  • Alternative treatments may be more or less invasive, with varying recovery times and risk profiles compared to pneumocentesis.

Patient Experience

During the Procedure:

  • Patients may feel pressure or mild discomfort at the site of needle insertion.
  • Sedation or anesthesia helps to minimize pain and anxiety.
    After the Procedure:
  • Pain is typically managed with over-the-counter pain relievers or prescribed medications.
  • Patients may feel tired or have a slight discomfort for a short period post-procedure.
