Chest Intubation(Tube thoracostomy)

Chest Intubation (Tube Thoracostomy), also known as chest tube insertion, is a medical procedure used to drain air, fluid, or blood from the pleural space (the space between the lungs and the chest wall). It is typically performed in emergency situations or as part of the management of various conditions that affect the lungs or pleural space.

Indications for Tube Thoracostomy:

A chest tube is commonly inserted in the following clinical situations:

• Pneumothorax (collapsed lung): Air accumulates in the pleural space, causing the lung to collapse. This may result from trauma, a spontaneous rupture of lung tissue, or underlying lung diseases like emphysema.
• Hemothorax: Blood collects in the pleural space, often due to trauma, surgery, or certain diseases. The tube allows for drainage of the blood to prevent lung compression and respiratory distress.
• Pleural Effusion: Fluid accumulation in the pleural space, often caused by infection, cancer, heart failure, or other conditions. The chest tube is used to remove the fluid and alleviate symptoms.
• Chylothorax: A condition where lymphatic fluid (chyle) accumulates in the pleural space, usually due to trauma or blockage of the thoracic duct.
• Post-surgical drainage: After thoracic surgeries (e.g., lung surgery, heart surgery), a chest tube may be placed to prevent fluid accumulation and to ensure the lungs re-expand properly.
• Empyema (infection in the pleural space): Infections that result in pus accumulation in the pleural space require chest tube placement for drainage and to allow antibiotics to reach the infected area.

Procedure for Chest Tube Insertion:

Preparation:

• Informed Consent: The patient is usually informed of the procedure, its risks, and benefits.
• Anesthesia: Local anesthesia is used at the insertion site to numb the area, and sometimes a mild sedative is given to keep the patient calm.
• Positioning: The patient is typically positioned either lying on their back or sitting up, depending on the situation. The area of insertion is cleaned and sterilized.

Insertion:

• The doctor identifies the appropriate site for insertion, usually between the ribs, in the mid-axillary line (around the side of the chest).
• A small incision is made in the skin, and a blunt dissection is performed to reach the pleural space.
• A chest tube (a flexible plastic tube) is inserted into the pleural space. It is guided through the incision and into the pleura to either drain air (in pneumothorax) or fluid/blood (in hemothorax or pleural effusion).
• The tube is connected to a drainage system, which helps remove the air, blood, or fluid from the chest.

Securing the Chest Tube:

• The tube is secured in place with sutures and a dressing to prevent accidental displacement.
• The tube is connected to a drainage system that may include a one-way valve or water seal to allow fluid or air to drain out but prevent it from entering back into the pleural space.

Post-Insertion Care:

• The patient is monitored for any complications, such as infection, bleeding, or displacement of the chest tube.
• The amount and type of fluid or air being drained are carefully observed.
• X-rays may be done after the procedure to confirm the tube is positioned correctly and to assess lung re-expansion.

Chest Tube Drainage Systems:

Chest tube drainage systems are designed to allow the air, blood, or fluid to drain out of the pleural space while preventing the backflow of air or fluid into the chest. The most common types include:

• Water Seal Drainage System: A one-way valve or water column allows air to exit but prevents it from re-entering the pleural space.
• Suction Drainage System: In some cases, gentle suction is applied to help drain air or fluid more effectively.

Risks and Complications:

Although chest tube insertion is generally a safe procedure, it can have potential complications, such as:

• Infection: Infection at the insertion site or in the pleural space (empyema).
• Bleeding: Bleeding from the lung or intercostal blood vessels.
• Damage to surrounding organs: Damage to surrounding organs (e.g., lungs, heart, diaphragm, spleen, or liver), especially in the case of a poorly placed chest tube.
• Pneumothorax: Recurrent air leakage into the pleural space after tube insertion.
• Pain: Pain from the chest tube, which can be significant and may require analgesia.
• Tube Displacement: If the tube shifts or becomes dislodged, drainage can be impaired.
• Subcutaneous Emphysema: Air may enter the tissues under the skin if the chest tube becomes disconnected.

Post-Procedure Monitoring:

• Chest X-ray: To check the position of the tube and ensure that the lung has re-expanded.
• Drainage Observation: Monitoring the amount and nature of the drainage (air, blood, or fluid).
• Vital Signs: Close monitoring of respiratory status, heart rate, and oxygen saturation.
• Pain Management: Adequate pain control is provided, as chest tube placement can be quite uncomfortable.

Chest Tube Removal:

• The chest tube is typically removed when the drainage stops or significantly decreases, and the lung has fully re-expanded. This is confirmed by clinical assessment and imaging (e.g., chest X-ray).
• Procedure: The tube is removed by cutting the sutures and gently pulling the tube out. A sterile dressing is placed over the site. The patient is monitored for any signs of lung collapse (pneumothorax) after removal.

Conclusion:

Chest tube insertion is a crucial intervention for managing a variety of thoracic conditions, including pneumothorax, hemothorax, pleural effusion, and more. While it is a generally safe procedure, it requires careful technique and post-procedure monitoring to avoid complications. The procedure helps prevent respiratory distress, improve lung function, and manage symptoms effectively.
