Pulmonology focuses on diagnosing and treating lung and airway conditions such as asthma, COPD, and pneumonia, as well as overall respiratory health.

Therapeutic Strategy and Goals

How doctors treat pneumothorax depends on the size of the air leak, the patient’s symptoms, any existing lung disease, and whether it has happened before. The main goals are to remove the air, re-expand the lung, ease symptoms, and prevent it from coming back. At Liv Hospital, we use a step-by-step approach, from simple observation for small cases to surgery for more serious or repeated cases.

Observation (Conservative Management)

PULMONOLOGY

For small, primary spontaneous pneumothoraces in clinically stable patients with minimal symptoms, observation may be sufficient.

  • Oxygen Therapy: Supplemental oxygen is often administered even if saturations are normal. Breathing high concentrations of oxygen creates a nitrogen gradient that accelerates the resorption of pleural air by the capillaries. This can increase the absorption rate by 4-fold.
  • Monitoring: Patients are typically observed for 4-6 hours with repeat chest X-rays to ensure the pneumothorax is not enlarging. If stable, they may be discharged with close follow-up.

Needle Aspiration

PULMONOLOGY

If a primary pneumothorax is large or symptomatic, but the patient is stable, simple needle aspiration may be attempted.

  • Procedure: A small catheter is inserted into the second intercostal space at the mid-clavicular line. Air is manually aspirated using a syringe until resistance is felt or the total volume aspirated reaches a limit (e.g., 2.5-4 liters).
  • Success Rate: This technique is less invasive than a chest tube and avoids hospital admission in many cases if the lung re-expands and no air leak persists.

Tube Thoracostomy (Chest Tube)

Insertion of a chest tube is the standard treatment for large, unstable, or secondary pneumothoraces, as well as traumatic cases.

  • Placement: A flexible plastic tube is inserted through the chest wall (usually the 4th or 5th intercostal space in the mid-axillary line) into the pleural space.
  • Drainage System: The tube is connected to a water-seal drainage system (like a Pleur-evac). This allows air to escape the chest during exhalation or coughing, but prevents it from re-entering.
  • Suction: Suction may be applied to the system to pull air out and facilitate lung re-expansion actively, particularly if there is a persistent air leak.
  • Small-Bore vs. Large-Bore: Smaller “pigtail” catheters (8-14 French) are increasingly used for spontaneous pneumothorax as they are less painful and often as effective as larger surgical tubes.

Management of Tension Pneumothorax

Tension pneumothorax requires immediate needle decompression before any other steps.

  • Needle Decompression: A large-bore needle is inserted into the 2nd intercostal space, mid-clavicular line, or the 4th/5th intercostal space, anterior axillary line. This converts the tension pneumothorax into a simple open pneumothorax, relieving the pressure on the heart.
  • Definitive Treatment: This is a temporizing measure and must be followed immediately by the insertion of a chest tube.

Surgical Intervention: VATS

Surgery is indicated for recurrent pneumothorax, persistent air leaks (lasting >3-5 days), bilateral pneumothorax, hemothorax, or first-time episodes in high-risk professions (e.g., pilots, divers).

  • Video-Assisted Thoracoscopic Surgery (VATS): This minimally invasive technique is the gold standard. A small camera and instruments are inserted through tiny incisions.
  • Bullectomy: The surgeon identifies and staples off the ruptured blebs or bullae responsible for the leak.
  • Pleurodesis: To prevent recurrence, the pleural space is obliterated. This can be done mechanically (by abrasion of the parietal pleura) or chemically (by instilling agents such as talc). This creates inflammation and scarring that fuses the lung to the chest wall, leaving no space for air to accumulate.

Chemical Pleurodesis

For patients who are not surgical candidates, chemical pleurodesis can be performed through the chest tube.

  • Agents: Sterile talc slurry, doxycycline, or bleomycin are instilled into the pleural space.
  • Mechanism: These agents induce an intense inflammatory reaction (pleuritis) that causes fibrosis and adhesion between the visceral and parietal pleura. Talc is generally considered the most effective agent.

Heimlich Valve

For patients with a persistent but small air leak who are otherwise stable, a Heimlich valve (or a flutter valve) may be attached to the chest tube.

  • Ambulatory Management: This one-way valve allows air to escape but not enter. It will enable the patient to be mobile and potentially discharged home while the lung heals, avoiding prolonged hospitalization.

Management of Catamenial Pneumothorax

Treatment involves a combination of respiratory and gynecological interventions.

  • Surgery: VATS to resect endometrial implants and repair diaphragmatic defects.
  • Hormonal Therapy: Gonadotropin-releasing hormone (GnRH) agonists or oral contraceptives are used to suppress ovulation and prevent the cyclic hormonal changes that trigger the condition.

FREQUENTLY ASKED QUESTIONS

What is the purpose of a chest tube?

A chest tube acts as a drain; it is inserted through the ribs to remove trapped air (or fluid) from the pleural space, allowing the lung to re-expand and stick back to the chest wall.

Yes, breathing high concentrations of supplemental oxygen helps the body absorb the trapped nitrogen air in the chest cavity much faster, speeding up lung re-expansion.

 Pleurodesis is a procedure in which the lung lining is intentionally irritated (mechanically or with chemicals such as talc) to make it adhere to the chest wall, preventing the lung from collapsing again.

Surgery is usually recommended if you have a second pneumothorax, if the first one doesn’t heal with a tube after a few days, or if you have a high-risk job like flying or diving.

It is done in life-threatening emergencies where survival is the priority; while it involves a needle stick, the relief from the suffocating pressure of a tension pneumothorax is immediate.
