Thoracostomy (Chest Tube Insertion)

Overview

Thoracostomy, commonly known as chest tube insertion, is a medical procedure used to drain air, fluid, or pus from the pleural space (the area between the lungs and the chest wall). It is most often performed to treat conditions like pneumothorax (collapsed lung), pleural effusion (fluid accumulation), or empyema (pus accumulation due to infection).

The procedure involves inserting a flexible tube (chest tube) through the chest wall into the pleural space, which allows trapped air or fluid to be evacuated, improving breathing and lung function.

How is Thoracostomy (Chest Tube Insertion) Done?

Pre-procedural Evaluation:
  • Detailed history and physical exam to confirm the diagnosis.
  • Chest imaging (usually chest X-ray or CT scan) to identify the location and extent of air/fluid in the pleural space.
  • Laboratory tests may include a complete blood count (CBC), coagulation studies (to check for bleeding disorders), and electrolyte panels.
Patient Preparation:
  • Informed consent is required, explaining the risks, benefits, and procedure.
  • Patients are asked to fast for several hours if general anesthesia is being considered.
  • Sedation or local anesthesia is often used to minimize discomfort.
  • Sterile technique is necessary to prevent infection during the procedure.
Equipment Preparation:
  • Chest tube of the appropriate size (French gauge based on the patient’s size and underlying condition).
  • Sterile dressing supplies.
  • Drainage system (either water seal or suction).
  • Syringes, scalpels, sutures, and local anesthetic.

  • Positioning: The patient is usually positioned in a semi-upright or supine position with the arm on the affected side raised above the head to expose the chest.
  • Local Anesthesia: Local anesthetic (like lidocaine) is injected into the area where the chest tube will be inserted, typically between the 4th and 5th intercostal space, along the mid-axillary line.
  • Incision: A small incision (approximately 2-3 cm) is made, and a dissecting instrument is used to bluntly create a pathway to the pleural space.
  • Tube Insertion: The chest tube is gently inserted through the incision into the pleural cavity. The tube is directed either upward for pneumothorax or downward for fluid drainage.
  • Securing the Tube: The tube is sutured in place and connected to a drainage system. The chest tube can be attached to gravity drainage, a water seal system, or suction based on the clinical indication.
Post-Insertion Care:
  • A chest X-ray is obtained post-procedure to confirm the position of the chest tube.
  • Monitoring for drainage output, air leaks, and lung re-expansion is done continuously.

  • Bleeding: Injury to the intercostal vessels during insertion may lead to significant bleeding.
  • Infection: Infection at the insertion site or within the pleural space can occur, especially if sterile techniques are compromised.
  • Organ Injury: Misplacement of the chest tube can damage nearby organs such as the lung, heart, diaphragm, or liver/spleen.
  • Persistent Air Leak: Sometimes the lung fails to re-expand properly, leading to ongoing air leaks from the pleural space.
  • Re-expansion Pulmonary Edema: Rapid re-expansion of a collapsed lung can lead to pulmonary edema, a rare but serious complication.
  • Tube Blockage: Clots, fluid, or tissue can obstruct the chest tube, requiring re-adjustment or replacement.
What are the Benefits of Thoracostomy ?
  • Restores lung function by re-expanding collapsed lungs.
  • Relieves symptoms such as shortness of breath and chest pain.
  • Prevents serious complications like infection (e.g., empyema) or tension pneumothorax (life-threatening pressure build-up).
  • Facilitates further diagnostic testing by allowing fluid drainage for laboratory analysis.

Infrastructure and Facilities Required

Bronchoscopy Suite:
  • Sterile Environment: Thoracostomy should be performed in a sterile area such as an operating room, emergency room, or ICU.
  • Imaging Equipment: Imaging tools like X-rays or ultrasound are often used for guidance during or after the procedure.
  • Emergency Resuscitation Equipment: Since thoracostomy is an invasive procedure, emergency equipment (such as a defibrillator, oxygen, and airway management tools) should be on hand.
  • Drainage Systems: Various drainage systems (water seal, suction) need to be available for proper tube function.
  • Post-procedure Monitoring: A well-equipped ICU or ward is necessary to monitor the patient for signs of complications, with continuous monitoring of vital signs and chest tube function.

FAQs

Local anesthetic is used to numb the area. There might be discomfort during the procedure, but pain is typically well-controlled with medication.

The duration depends on the condition being treated, but tubes generally stay in place until no more air or fluid is draining, and the lung has fully re-expanded. This can range from a few days to over a week.

If the tube becomes dislodged, it is critical to inform medical staff immediately, as this can cause air or fluid to reaccumulate in the pleural space.

Movement is possible, but patients need to be cautious and follow specific instructions from their healthcare team to avoid dislodging the tube.

After the chest tube is removed, patients may need follow-up imaging to ensure the lung remains expanded and there is no reaccumulation of air or fluid.

This comprehensive guide outlines the basics of thoracostomy, ensuring patients and healthcare providers are aware of what to expect during this critical procedure.
