Mastering Chest Tube Removal: A Comprehensive Guide for Healthcare Professionals

Chest tubes are essential medical devices used to drain fluid, air, or blood from the pleural space (the area between the lung and the chest wall). While their insertion is often a life-saving procedure, their removal is equally crucial and requires meticulous attention to detail to minimize complications. This comprehensive guide provides a detailed, step-by-step approach for healthcare professionals involved in chest tube removal, focusing on best practices and safety measures.

Understanding Chest Tubes and Their Purpose

Before diving into the removal process, it’s essential to understand the basics of chest tubes. They are typically placed in cases of pneumothorax (collapsed lung), hemothorax (blood in the pleural space), pleural effusion (fluid buildup), and empyema (pus in the pleural space). The tube, connected to a drainage system, allows for the removal of unwanted substances, restoring negative pressure and facilitating proper lung expansion.

Types of Chest Tubes

While the underlying principle remains the same, there are different sizes and types of chest tubes based on the patient’s age and the condition being treated. These range from small pigtail catheters to larger-bore tubes used in cases with more significant drainage. It’s essential to know the specific type of tube being removed to tailor the approach if needed.

Pre-Removal Assessment: Ensuring Patient Readiness

Careful patient assessment is the first critical step before attempting chest tube removal. Several factors must be considered to ensure the patient is stable and ready for the procedure.

Clinical Stability

• Resolution of the Underlying Condition: The reason for chest tube placement must be resolved. For example, the pneumothorax should have resolved on follow-up imaging.
• Stable Vital Signs: The patient’s vital signs (heart rate, blood pressure, respiratory rate, and oxygen saturation) must be within acceptable ranges. Significant instability should be addressed before proceeding.
• Minimal or No Drainage: Drainage from the chest tube should be minimal (less than 100-200 mL in 24 hours, depending on the patient’s size, underlying conditions, and hospital protocols), with no evidence of ongoing bleeding or active air leak.
• Absence of Air Leak: An air leak can be detected by bubbles in the water seal chamber of the chest drainage system. An absence of an air leak suggests the lung has healed and is no longer leaking air into the pleural space.
• Pain Control: Patients should have adequate pain management before and during the procedure. Unmanaged pain can lead to increased anxiety and discomfort.

Imaging and Laboratory Data

• Chest X-Ray: A recent chest X-ray is crucial to confirm the resolution of the underlying condition, adequate lung expansion, and the absence of any new pathology. It also helps verify the proper positioning of the tube if needed, before removal.
• Laboratory Tests: Blood counts may be indicated to rule out ongoing bleeding or infection, especially if significant drainage was present.

Patient Education and Consent

• Explanation of the Procedure: Explain the removal process to the patient in simple terms, addressing their concerns and fears. Make them understand that there might be some pain or discomfort but is usually very tolerable.
• Obtaining Informed Consent: Obtain informed consent from the patient or their legal guardian after a detailed explanation of the procedure and potential risks. This must be documented according to institutional policies.

Gathering Necessary Supplies

Having all the required supplies at hand is crucial for a smooth and efficient removal process. The following items are typically required:

• Sterile Gloves: Several pairs, to maintain sterility during the procedure.
• Sterile Gauze Pads: For cleaning the area and dressing the site post removal.
• Antiseptic Solution: Chlorhexidine or povidone-iodine for skin preparation.
• Sutures Removal Kit: If the chest tube is secured with sutures, a suture removal kit including scissors and forceps is needed.
• Petroleum Jelly Impregnated Gauze: To create an occlusive dressing and prevent air from re-entering the pleural space.
• Adhesive Tape: To secure the dressing in place.
• Clean Dressing Materials: For an overall dressing that is not only occlusive but also absorbent.
• Sharps Container: To dispose of contaminated materials safely.
• Pain Medication: To administer before or after the procedure if needed.

Step-by-Step Guide to Chest Tube Removal

Following a systematic approach is essential for safe and effective chest tube removal. Here are the detailed steps involved:

Step 1: Hand Hygiene and Preparation

Begin with thorough hand hygiene using soap and water or an alcohol-based hand sanitizer. Place all the needed supplies within reach.

Step 2: Patient Positioning

Position the patient comfortably, usually in a semi-recumbent or sitting position. This facilitates breathing and allows easy access to the chest tube site. Ensure the patient is supported and comfortable to tolerate the process.

Step 3: Skin Preparation

Put on sterile gloves and thoroughly clean the skin around the chest tube insertion site using an antiseptic solution. Allow the antiseptic to dry completely before proceeding to ensure optimal disinfection. This minimizes the risk of infection.

Step 4: Suture Removal

If the chest tube is secured with sutures, use a suture removal kit to carefully cut and remove them. Ensure you do not accidentally pull on the chest tube during this process. Once the sutures are removed, the chest tube is only held in place by the dressing and the patient’s skin.

Step 5: Patient Instructions and Deep Breath

Instruct the patient to take a deep breath in and hold it while you remove the chest tube. This maneuver creates positive pressure in the lungs, minimizing the risk of air entry into the pleural space during the process. Some clinicians also prefer having the patient perform a forceful exhale at the time of the pull. Communicate clearly and concisely before the maneuver.

Step 6: Chest Tube Removal

Firmly grasp the chest tube near the insertion site and, with a quick, steady motion, remove it. Do not hesitate once you have begun the pulling maneuver. Some patients may require a forceful pull due to tissue adherence to the tube; this is normal. Have the petroleum jelly impregnated gauze ready to apply right after.

Step 7: Application of Petroleum Jelly Impregnated Gauze

Immediately after removal, quickly apply the petroleum jelly-impregnated gauze over the insertion site. This is crucial to create an occlusive seal and prevent air from entering the pleural space.

Step 8: Secure Dressing

Apply a clean and absorbent dressing over the petroleum jelly gauze using adhesive tape. Ensure the dressing is secure and covers the entire site appropriately. The tape should be secured with firm and even pressure. Avoid wrinkles in the tape that could cause the dressing to become loose.

Step 9: Patient Monitoring and Assessment

After the procedure, closely monitor the patient for any signs of respiratory distress, such as increased shortness of breath, chest pain, changes in vital signs, or development of subcutaneous emphysema (air under the skin). Assess the dressing for signs of drainage or leakage. Auscultate the patient’s lung sounds to assess if there is new or persistent air leak and/or any lung collapse. If new or persistent air leak is identified, a new chest X-ray should be done and chest tube reinsertion may be needed.

Step 10: Post Removal Imaging

A follow-up chest X-ray is often done within a few hours of the removal of the chest tube. This is to ensure that no pneumothorax has occurred due to the procedure.

Potential Complications of Chest Tube Removal

While chest tube removal is generally a safe procedure, some potential complications can occur. It is essential to be aware of these and to take appropriate measures to prevent them:

Pneumothorax

A pneumothorax is the most significant risk associated with chest tube removal, where air enters the pleural space after the tube removal. Using petroleum jelly impregnated gauze immediately after removal will prevent this. Continuous monitoring is required to identify this complication early.

Subcutaneous Emphysema

Air may leak into the subcutaneous tissues, causing swelling, crepitus and sometimes pain. This is often self-limiting and usually resolves with time. However, the provider must still monitor the patient for this complication.

Infection

Infection at the insertion site is rare but can occur if proper aseptic techniques are not followed. Meticulous skin preparation and sterile technique are essential to avoid this.

Bleeding

Bleeding at the insertion site can occur, especially in patients with bleeding disorders. Direct pressure should control most minor bleeding episodes. If significant bleeding is noted, further evaluation is needed.

Pain

Some patients experience pain at the site after tube removal. Providing adequate pain control is an essential part of the procedure. Simple pain relievers and ice packs can help relieve pain.

Troubleshooting During Chest Tube Removal

Sometimes, unexpected situations can arise during chest tube removal. Here are a few common scenarios and solutions:

Difficult Tube Removal

If the tube is difficult to remove, do not forcefully pull it. Assess whether sutures were completely removed. Try to gently manipulate the tube, moving it slightly to break any adhesions to the surrounding tissue. Sometimes, a few more moments are needed before pulling the tube. If significant resistance is noted, notify a supervising physician.

Significant Bleeding

Apply direct pressure to the insertion site. If bleeding does not stop, notify a physician immediately. The physician might be needed to help with applying sutures or use chemical or surgical hemostasis.

Respiratory Distress

If the patient experiences respiratory distress after removal, provide supplemental oxygen immediately and have them assessed as soon as possible. Perform a quick assessment with auscultation of the chest, vital signs, pulse oximetry, and any other pertinent assessment. A stat chest X-ray may be necessary.

Best Practices for Chest Tube Removal

To ensure successful chest tube removal, follow these best practice guidelines:

• Adhere to protocols: Follow institutional protocols for chest tube removal, including documentation and reporting requirements.
• Teamwork: Work with a team or a trained colleague for the process. If this is not possible, make sure you have a trained nurse or staff member to support.
• Clear Communication: Maintain clear and concise communication with the patient throughout the procedure.
• Continuous Learning: Stay updated on the latest evidence-based guidelines for chest tube management.
• Documentation: Document the procedure, patient response, and any complications according to institutional standards and protocols.
