Pneumothorax, often called a collapsed lung, occurs when air leaks into the space between the lung and chest wall, creating pressure that can cause the lung to deflate. Treatment strategies vary widely depending on how much of the lung has collapsed, whether underlying diseases are present, and the risk of recurrence.

Approaches to Managing a Collapsed Lung

The main goal when treating pneumothorax is to relieve the pressure on the lung so it can expand again and restore normal breathing. Doctors also aim to prevent the problem from happening again, which is particularly important since many people who experience one collapsed lung are at risk of having another episode. The approach taken depends on several factors, including how large the pneumothorax is, what caused it, whether the person has existing lung disease, and how severe the symptoms are.^[1][9]

Treatment decisions are guided by careful assessment of the patient’s condition. A small pneumothorax in an otherwise healthy person might heal on its own with close monitoring, while a larger collapse or one occurring in someone with chronic lung disease often requires immediate intervention. The presence of symptoms like severe chest pain, rapid breathing, or low blood oxygen levels signals the need for more aggressive treatment.^[2][15]

Medical guidelines from different professional societies recommend various strategies, but all emphasize the importance of matching the treatment to the individual patient’s situation. Some people can be managed as outpatients with regular follow-up visits, while others need hospital admission and continuous monitoring. Understanding the natural course of pneumothorax and the benefits and limitations of each treatment option helps doctors and patients make informed decisions together.^[15]

Standard Treatment Options

The simplest approach to treating pneumothorax is observation, sometimes called watchful waiting. This conservative strategy is used when only a small portion of the lung has collapsed and the person is not experiencing significant breathing difficulties. During this time, the body naturally reabsorbs the air that has leaked into the pleural space. Patients are monitored with repeated chest X-rays over several weeks to ensure the lung is gradually re-expanding. Supplemental oxygen may be provided through a mask to speed up the absorption of air and help the lung expand more quickly.^[9][5]

For larger pneumothoraces or when symptoms are troubling, doctors use procedures to actively remove the trapped air. Needle aspiration involves inserting a hollow needle with a small flexible tube, called a catheter, between the ribs into the air-filled space. The doctor then attaches a syringe to the catheter and pulls out the excess air. This procedure can provide immediate relief and may be all that’s needed for some patients. The catheter might be left in place for a few hours to make sure the lung stays expanded and the pneumothorax doesn’t come back right away.^[9]

When a larger area of the lung has collapsed, a chest tube insertion is often necessary. This procedure involves placing a larger tube between the ribs into the pleural space. The tube is connected to a one-way valve system that allows air to escape but prevents it from flowing back in. The chest tube typically stays in place for several days while the lung re-expands and the air leak seals. Patients with chest tubes usually need to remain in the hospital during this time so medical staff can monitor their progress and ensure the system is working properly.^[9][15]

Pain management is an important part of standard treatment. Chest pain from pneumothorax can be quite severe, and the discomfort may worsen with breathing or coughing. Doctors commonly prescribe pain medications to keep patients comfortable during recovery. Some physicians use intercostal nerve blocks, which involve injecting local anesthetic medication near the nerves between the ribs to reduce pain without requiring as much narcotic medication. This can help patients breathe more comfortably and participate in deep breathing exercises that promote lung expansion.^[8][15]

When antibiotics are needed, they are typically given intravenously (through a vein) to treat underlying infections that may have contributed to the pneumothorax or to prevent infections that can develop from having a chest tube in place. Research suggests that giving preventive antibiotics when inserting a chest tube may reduce complications. The specific antibiotic chosen depends on whether there’s an active infection and which bacteria are suspected or identified.^[8]

Surgical Approaches for Prevention and Treatment

Surgery becomes an important consideration when pneumothorax recurs or when there’s a high risk it will happen again. The most common surgical procedure is pleurodesis, which aims to prevent future episodes by creating adhesions between the lung surface and the chest wall. This eliminates the space where air can accumulate. Pleurodesis can be performed in different ways, either mechanically or chemically.^[9][12]

Mechanical pleurodesis involves physically abrading or roughening the pleural surfaces during surgery. Surgeons use gauze or a rough pad to irritate the tissue, which triggers an inflammatory response that causes the lung and chest wall lining to stick together as they heal. This technique is often preferred because it tends to be more reliable than chemical methods in creating a complete seal across the entire pleural space.^[12]

Chemical pleurodesis can be performed through a chest tube without surgery, or during a surgical procedure. Substances like talc, doxycycline, or bleomycin are introduced into the pleural space to irritate the tissues and cause them to adhere. While chemical pleurodesis through a chest tube is less invasive than surgery, it may not be as effective because the chemical may not distribute evenly throughout the pleural space, potentially leaving areas where air could accumulate in the future.^[12][13]

The most commonly used surgical technique today is video-assisted thoracoscopic surgery (VATS). This minimally invasive approach involves making several small incisions (about the size of a fingertip) in the chest wall. Surgeons insert a camera and specialized instruments through these small openings to perform the procedure while viewing the inside of the chest on a video monitor. VATS allows doctors to examine the lung surface, identify any blebs or bullae (abnormal air-filled pockets) that might have caused the pneumothorax, and perform mechanical pleurodesis to prevent recurrence.^[12][15]

The advantages of VATS compared to traditional open chest surgery (thoracotomy) are significant. Patients typically experience less pain after the procedure, spend fewer days in the hospital, and return to normal activities more quickly. The smaller incisions also result in better cosmetic outcomes and lower risk of complications. However, VATS still requires general anesthesia and the expertise of a thoracic surgeon experienced in this technique.^[12]

For patients with underlying lung disease like lymphangioleiomyomatosis (LAM), surgical management requires special considerations. Women with LAM have a very high risk of recurrent pneumothorax—about 75% will experience another episode if nothing is done to prevent it. In these patients, most thoracic surgeons recommend pleurodesis after the first pneumothorax rather than waiting for a recurrence. The surgical approach should be performed by a thoracic surgeon experienced with LAM patients whenever possible. One important consideration is that resecting (cutting out) the specific cysts that caused the air leak is generally not recommended in LAM because it’s often impossible to identify which cyst was responsible, and placing surgical staples in diseased LAM lung tissue can lead to prolonged air leaks that are difficult to manage.^[12][21]

Recurrence rates after surgical pleurodesis vary depending on the patient’s underlying condition. In otherwise healthy individuals, the recurrence rate is relatively low. However, in patients with LAM, even after aggressive mechanical pleurodesis performed using VATS, the recurrence rate is reported to be around 25 to 30 percent. While this is much better than the 65 percent recurrence rate with conservative management, it means some patients may need additional interventions in the future.^[12][21]

In rare cases when VATS is not successful or appropriate, thoracotomy (open chest surgery) may be necessary. This involves making a larger incision and spreading the ribs to access the chest cavity directly. Thoracotomy allows the surgeon to perform more extensive procedures, such as pleurectomy (removing part of the pleural lining) or treating complications that cannot be managed with minimally invasive techniques. Because it’s a more invasive procedure, recovery takes longer and patients generally experience more pain compared to VATS.^[15]

Specialized Care Considerations

Certain aspects of pneumothorax management require specialized attention and expertise. When surgery is planned, the choice of anesthesiologist can impact outcomes. It’s important that the anesthesiologist be experienced with thoracic surgical procedures in patients with lung disease. They need to use protective lung strategies during surgery, such as maintaining low airway pressures, to minimize the risk of worsening the pneumothorax or causing additional lung injury. Some centers use epidural catheters for postoperative pain management, which can provide excellent pain control and help patients breathe more comfortably during recovery.^[12][21]

For patients with spontaneous pneumothorax related to underlying diseases like chronic obstructive pulmonary disease (COPD), asthma, cystic fibrosis, or tuberculosis, treating the underlying condition is essential. Medications to manage these diseases—such as bronchodilators for COPD or antibiotics for infections—may be necessary alongside the treatment for the collapsed lung itself. Addressing the root cause helps reduce the risk of future episodes.^[3][8]

Follow-up care after pneumothorax treatment is crucial. Patients typically need repeated chest X-rays to confirm the lung has fully re-expanded and remains inflated. Doctors will want to monitor progress over several weeks to months. During this recovery period, patients are usually advised to avoid activities that could increase the risk of recurrence, such as flying in airplanes or scuba diving, until their doctor confirms it’s safe. Strenuous exercise may also need to be limited initially.^[17][19]

Treatment Approaches Being Studied in Clinical Research

While the provided sources focus primarily on established treatment methods for pneumothorax, they do not contain detailed information about specific experimental therapies, novel drug molecules, or ongoing clinical trials investigating new treatments for this condition. The management strategies described—including observation, aspiration, chest tube drainage, and surgical pleurodesis—represent standard, well-established approaches rather than investigational treatments being tested in formal clinical trial settings.

Research continues in understanding the underlying mechanisms that cause spontaneous pneumothorax, particularly in identifying genetic factors in familial pneumothorax and understanding why blebs and bullae form on lung surfaces. Studies are also examining optimal surgical techniques and comparing outcomes between different approaches, but these represent refinements of existing methods rather than entirely new therapeutic strategies.^[22]
