Tube thoracostomy is the medical term for inserting a chest tube, a flexible plastic tube placed through the chest wall into the space between the lungs and the ribcage. It is one of the most commonly performed emergency and bedside procedures in medicine, used to drain air, blood, pus, or other fluid that has no business being in that space. The procedure has been around in some form since antiquity, but the techniques, tube sizes, and management strategies have evolved considerably, and the choices clinicians face today are more nuanced than “put a tube in and wait.”
Why a Chest Tube Gets Placed
The space between the lung and the chest wall, called the pleural space, normally contains only a thin film of fluid that lets the lung slide smoothly as you breathe. When something disrupts that balance, it can cause serious problems. A pneumothorax means air has leaked into the space, which can partially or fully collapse the lung. A hemothorax means blood has accumulated there, usually after trauma. Pleural effusions involve other types of fluid, including infection-related collections called empyema. In all of these situations, the chest tube provides a route for the unwanted material to leave the body so the lung can re-expand and do its job.
In trauma settings, the chest tube often addresses blood or air from rib fractures, stab wounds, or blunt force injuries. Outside of trauma, the reasons are just as varied. In one study from a low-income setting, more than 90% of chest tubes were placed for non-traumatic conditions, with the most common indication being pleural effusion. A large proportion of those patients had tuberculosis, and nearly two-thirds of the TB patients also had HIV infection, reflecting how local disease patterns shape who needs the procedure and why.1PubMed Central.

Large-Bore Tubes Versus Pigtail Catheters
For years, the default chest tube was a large-bore device, often in the range of 28 to 36 French (roughly the diameter of your index finger). These are still used, particularly in trauma when thick blood or clots need to drain quickly. But a growing body of evidence has pushed clinicians toward smaller-bore pigtail catheters for many situations. These are thin, flexible catheters with a coiled tip that anchors them in place. They are inserted with the Seldinger technique, threading the tube over a guidewire rather than making a blunt incision through the chest wall muscle.
In a randomized trial of patients with uncomplicated traumatic pneumothorax, pigtail catheters produced dramatically less pain than traditional chest tubes. Pain scores at the time of insertion were roughly half those of the chest tube group, and the difference persisted through at least the second day. Success rates and complication rates were similar between the two groups.2PubMed. Randomized clinical trial of pigtail catheter versus chest tube in injured patients with uncomplicated traumatic pneumothorax A pediatric study found similar results in children with spontaneous pneumothorax: pigtail catheters led to fewer X-rays and shorter courses of oral pain medication, with no difference in hospital stay, tube replacement, or recurrence.3PubMed. Pigtail Catheter versus Large Bore Chest Tube for the Management of Spontaneous Pneumothorax in Children: A Retrospective Study
The concern with smaller tubes has always been whether they can handle thicker fluids like blood. An animal study comparing large chest tubes to pigtail catheters for hemothorax found that blood drained faster through the chest tube during the first few minutes, but the difference narrowed quickly, and the overall drainage amounts were not statistically different.4Journal of Trauma and Acute Care Surgery. A pilot study of chest tube versus pigtail catheter drainage of acute hemothorax in swine The takeaway is that pigtail catheters are a strong option for pneumothorax and many effusions, but clinicians still lean toward larger tubes when dealing with massive bleeding or thick infected material.
How Insertion Works and the Role of Ultrasound
Traditional large-bore chest tube insertion uses blunt dissection. The clinician makes a skin incision, pushes through the chest wall muscles with a clamp, enters the pleural space, sweeps a finger inside to confirm location, and then slides the tube in. It is a hands-on, somewhat forceful procedure, and it is the technique most emergency physicians and surgeons learn first.
The Seldinger technique, used primarily for smaller-bore tubes, is gentler. A needle punctures the pleural space, a guidewire is threaded through the needle, the needle is removed, and the tube slides over the wire into position. A recent series demonstrated that large-bore tubes (18 to 24 French) could also be placed using a modified Seldinger approach, with a median procedure time of about 17 minutes and no complications.5PubMed Central. Large-bore Chest Tube Insertion: Seldinger Technique over Two Guidewires
Ultrasound has become an increasingly important tool. It lets the clinician visualize exactly where fluid or air is sitting, identify the safest entry point, and avoid structures like the diaphragm or solid organs. A systematic review found no randomized trials specifically testing ultrasound-guided tube thoracostomy, but concluded that it is reasonable to expect that proper use of ultrasound reduces procedure-related complications.6PubMed. Can ultrasound be used as an adjunct for tube thoracostomy?

What Can Go Wrong
Tube malposition is the most common complication. The tube can end up inside the lung tissue itself, wedged into a fissure between lobes, or angled awkwardly within the pleural space. A prospective study of critically ill patients using CT scans to check tube position found that about 21% of tubes were sitting in a fissure and 9% had been pushed into the lung tissue. The only factor that predicted malposition in that study was the use of a trocar, a sharp-tipped inserter that has largely fallen out of favor for exactly this reason.8Anesthesiology. Incidence of Chest Tube Malposition in the Critically Ill: A Prospective Computed Tomography Study Blunt dissection remains the safer approach for traditional insertion.9PubMed Central. Tube Thoracostomy: Complications and Its Management
Injury to the intercostal artery and nerve bundle running along the underside of each rib is another concern. The tube should always be placed just above the rib below the target space, not just below the rib above it, because the neurovascular bundle tucks along the lower edge of each rib. Risk factors for this kind of injury include older age, obesity, multiple rib fractures, and placing the tube too close to the spine. Lateral placement, at least six centimeters from the spine, and choosing a more caudal (lower) rib space helps reduce this risk.10CHEST. Delayed Presentation of Intercostal Artery Laceration and Cardiac Arrest Following Chest Tube Removal
Re-expansion pulmonary edema is a rarer but dramatic complication. When a collapsed lung re-inflates too quickly, the lung tissue can become waterlogged, causing sudden respiratory distress. A meta-analysis identified smoking history, longer duration of symptoms before drainage, and larger pneumothorax size as the main risk factors.11PubMed Central. Risk factors for re-expansion pulmonary edema following chest tube drainage in patients with spontaneous pneumothorax: A systematic review and meta-analysis The underlying mechanism involves damage to the pulmonary blood vessels when the lung suddenly re-expands. Other recognized risk factors include young age (under 40), collapse lasting more than three days, lung re-expansion occurring in under 10 minutes, and draining more than 1.5 liters of fluid at once.12PubMed Central. Severe re-expansion pulmonary edema after chest tube insertion for the treatment of spontaneous pneumothorax: A case report Controlling the drainage rate, especially clamping the tube intermittently for large effusions, is one of the main preventive measures.
Antibiotics After Traumatic Chest Tubes
Whether to give preventive antibiotics after placing a chest tube for trauma has been debated for decades. Two meta-analyses provide fairly strong evidence that prophylactic antibiotics reduce infection rates when the tube is placed for a chest injury.
One meta-analysis found that antibiotic prophylaxis cut the rate of post-traumatic empyema from about 7% to 1% and roughly halved the rate of pneumonia. In practical terms, patients who received preventive antibiotics had about 75% lower risk of empyema and 59% lower risk of pneumonia compared to those given a placebo.13PubMed Central. Use of prophylactic antibiotic in preventing complications for blunt and penetrating chest trauma requiring chest drain insertion: a systematic review and meta-analysis A more recent guideline from a major trauma surgery association confirmed these findings, noting that the benefit appeared strongest in penetrating injuries. The guideline found no significant effect on mortality or overall pneumonia rates when analyzed by a slightly different pooling approach, which highlights that the data are consistent on empyema prevention but somewhat mixed on other endpoints.14PubMed Central. Antibiotic prophylaxis for tube thoracostomy placement in trauma: a practice management guideline from the Eastern Association for the Surgery of Trauma
For non-traumatic chest tubes, the evidence base is thinner, and routine prophylaxis is not standard practice. The case for antibiotics in trauma likely reflects the higher bacterial contamination from the injury itself combined with the foreign body of the tube creating a favorable environment for infection.
Removing the Chest Tube
A persistent question in chest tube care is when and how to pull the tube out. Traditionally, some clinicians removed tubes at the end of a full exhale (end-expiration), reasoning that the pleural space is smallest at that point. Others preferred end-inspiration, arguing the positive pressure inside the chest during breathing in helps prevent air from sneaking back in through the hole. A meta-analysis pooling available studies found no significant difference in recurrent pneumothorax or the need for a replacement tube between the two timing approaches. Hospital stays were, however, shorter in the group whose tubes were removed at end-inspiration.15PubMed. Thoracostomy tube withdrawal during latter phases of expiration or inspiration: a systematic review and meta-analysis
The results from individual trials give a slightly messier picture. One older randomized trial found essentially identical recurrence rates whether tubes were pulled during inspiration or expiration.16PubMed. Chest tube removal: end-inspiration or end-expiration? Another trial found that end-inspiration was superior and also observed that removing tubes too early, within 6 to 12 hours rather than waiting 24 to 48 hours, was associated with more recurrent pneumothorax.17Turkish Journal of Thoracic and Cardiovascular Surgery. Removal of chest tubes: a prospective randomized study The practical consensus is that both timing approaches are safe, with a slight lean toward end-inspiration when possible, and that waiting at least a day after the air leak stops before pulling the tube is a sensible precaution.
Dealing with Persistent Air Leaks
Most chest tubes can be removed within a few days, but some patients develop a persistent air leak, meaning air keeps bubbling through the drainage system long after it should have stopped. This is especially common in patients with underlying lung disease like emphysema, where the lung tissue is fragile and does not seal easily. For patients who are too sick or frail for surgery, the options used to be limited to waiting or trying chemical pleurodesis, a process where an irritant is injected into the pleural space to glue the lung to the chest wall.
Autologous blood patch pleurodesis has emerged as a middle-ground option. The clinician draws a sample of the patient’s own blood and injects it through the chest tube into the pleural space. The blood clots over the site of the leak and can seal it. A meta-analysis found that blood patch pleurodesis significantly reduced the time to air leak cessation compared to conservative management. The procedure did not significantly shorten overall hospital stays, and complication rates for infection, pain, and fever were no different from those in patients managed without the blood patch.18PubMed Central. The Efficacy and Safety of Autologous Blood Patch for Persistent Air Leaks: A Systematic Review and Meta-Analysis
Clinical series offer a more granular look. In one series of postoperative patients, the first blood patch resolved the air leak in about 64% of cases, and 95% of those responders saw resolution within 24 hours.19PubMed Central. Autologous blood patch pleurodesis for prolonged postoperative air leaks In another series focused on patients with secondary spontaneous pneumothorax who were poor surgical candidates, the success rate was about 72%, with roughly half of those resolving within a single day.20PubMed. Autologous Blood Patch Pleurodesis for the Management of a Persistent Air Leak after Secondary Spontaneous Pneumothorax It is a low-risk procedure that gives clinicians something to try before resorting to surgery, and the fact that it uses the patient’s own blood means there is no risk of allergic reaction to foreign materials.
Injecting Medications Through the Tube
The chest tube is not just a passive drain. In complicated pleural infections, where thick pus and fibrous debris partition the fluid into pockets that will not drain on their own, clinicians can deliver medications directly into the pleural space. The landmark trial in this area tested combinations of tissue plasminogen activator (tPA, a clot-dissolving drug) and DNase (an enzyme that breaks down DNA released by dead white blood cells, which makes the pus stringy and hard to drain). Only the combination of tPA and DNase together produced meaningful results: it cleared more of the infected fluid from the chest, reduced surgical referrals from about 16% to 4%, and shortened hospital stays by roughly a week compared to placebo. Neither drug worked well on its own.21PubMed. Intrapleural use of tissue plasminogen activator and DNase in pleural infection
Follow-up studies have confirmed the approach. A clinical series using once-daily dosing of the combination reported that over 90% of patients were managed successfully without surgery, with the most common side effect being chest pain requiring stronger pain medication in about 15% of patients.22PubMed. Management of Intrapleural Sepsis with Once Daily Use of Tissue Plasminogen Activator and Deoxyribonuclease A network meta-analysis comparing different intrapleural drugs confirmed that tPA-DNase combination and tPA alone both lowered the need for surgery compared to placebo, though the combination carried a higher bleeding risk.23PubMed. Choice of intrapleural fibrinolytic agents in the treatment of adult complicated parapneumonic effusion and empyema: Network meta-analysis For clinicians and patients, this means that a chest tube placed for a complicated infection is often doing double duty: draining fluid while also serving as the delivery system for treatments that can prevent a trip to the operating room.
Ambulatory Chest Tubes and Avoiding the Hospital
One of the more interesting shifts in chest tube management is the move toward outpatient treatment. Traditionally, any patient who needed a chest tube was admitted to the hospital and stayed until the tube came out. That model is being challenged, particularly for spontaneous pneumothorax in otherwise healthy people.
A Heimlich valve is a one-way flutter valve that attaches to a chest tube or small-bore catheter and drains into a portable bag. It lets air escape from the pleural space but prevents it from flowing back in. The patient can carry it around, walk, and in some cases go home.24PubMed Central. Heimlich valve and pneumothorax A 24-year experience with ambulatory small-bore catheters attached to Heimlich valves for pneumothorax reported a 93% success rate across 445 cases, with an average hospital stay of just over two days, zero deaths, and only one serious complication from an incorrectly placed catheter.25British Journal of Surgery. 71312 – Ambulatory True-Close Thoracic Vent, an outpatient management of Pneumothorax – results of 24 years’ experience
Even simpler than a chest tube is needle aspiration, where a clinician uses a needle and syringe to manually suck air out of the pleural space without leaving any tube behind. For first-time spontaneous pneumothorax, a meta-analysis of six studies found that needle aspiration shortened hospital stays by about a day and a half and reduced the admission rate compared to chest tube drainage, with no difference in immediate success rates or one-year recurrence.26PubMed Central. Chest tube drainage versus needle aspiration for primary spontaneous pneumothorax: which is better? A randomized trial confirmed that the immediate success of aspiration and tube drainage were comparable, at roughly 62% and 68% respectively.27European Respiratory Journal. Aspiration versus tube drainage in primary spontaneous pneumothorax: a randomised study The catch is that aspiration works best for simple, first-episode cases; patients with recurrent pneumothorax, large air leaks, or underlying lung disease generally still need a tube.
Chest Tubes in the Field
Placing a chest tube before the patient reaches the hospital is a reality in some emergency medical systems, particularly those staffed by physicians. In one review covering both prehospital and emergency department placements, 65 prehospital thoracostomies were performed, about 61% of which were for appropriate indications such as suspected tension pneumothorax or a patient in a low-output circulatory state. The overall complication rate was 14%, with 9% classified as major, and three patients required surgery to correct a problem related to the procedure.28PubMed Central. Pre-hospital and in-hospital thoracostomy: indications and complications
A separate study concluded that prehospital chest tube insertion by qualified physicians is both safe and lifesaving, and that infection rates from tubes placed in the field do not differ from those placed in the emergency department.29Journal of Trauma and Acute Care Surgery. Prehospital Chest Tube Thoracostomy: Effective Treatment or Additional Trauma? In many field situations, a simple thoracostomy (opening the chest wall without inserting a tube at all) is enough to relieve a tension pneumothorax and buy time for transport, with the tube placed under more controlled conditions in the hospital. The key variable is the skill of the operator and whether the clinical situation truly warrants the procedure before arrival at a facility.
Managing Pain Around the Tube
Having a chest tube is uncomfortable, and pain management deserves more attention than it sometimes gets. The tube passes through the chest wall muscles and sits against the sensitive pleural lining, producing pain that worsens with breathing, coughing, and movement. Poor pain control is not just a comfort issue: patients who cannot cough effectively are at higher risk for mucus plugging, pneumonia, and atelectasis (collapsed segments of lung).
Regional nerve blocks are an important tool. The erector spinae plane block, a relatively newer technique in which local anesthetic is injected near the muscles running along the spine, has been compared to traditional intercostal nerve blocks in a meta-analysis of thoracic surgery and chest wall trauma patients. The erector spinae block produced significantly lower pain scores at 1, 24, and 48 hours after the procedure. Opioid consumption at 24 and 48 hours was similar between the two techniques, and neither approach significantly changed hospital stay length.30Current Pain and Headache Reports. Erector Spinae Plane Block vs. Intercostal Nerve Block for Pain Management in Thoracic Surgeries and Chest Wall Traumas: A Meta-Analysis The practical message is that effective regional anesthesia can make a real difference in how tolerable a chest tube is, and using smaller-bore tubes where clinically appropriate also reduces pain at the source.
A Long History, Still Evolving
The concept of draining the pleural space dates back to Hippocrates, who described draining empyema with open incisions. The procedure went through centuries of refinement, achieving a major milestone in the 1800s with closed drainage systems that prevented air from re-entering the chest, a problem that had killed countless patients in earlier eras. The introduction of plastic tubing and the Heimlich valve in the twentieth century transformed what had been a tethered, bed-bound experience into something that could eventually allow patients to walk around or even go home.31PubMed Central. Chest Tubes and Pleural Drainage: History and Current Status in Pleural Disease Management Today’s developments, including smaller catheters, ultrasound-guided placement, intrapleural enzyme therapy, and ambulatory management, represent a trend toward doing less physical harm to the patient while getting the same or better results. The chest tube remains indispensable, but the way it is placed, managed, and eventually removed looks less like a one-size-fits-all procedure and more like a set of options tailored to the individual patient and their specific problem.
