1. Definition
Chest tube drainage, also called intercostal drainage (ICD) or tube thoracostomy, is a procedure in which a tube is inserted through the chest wall into the pleural space to remove air, blood, fluid or pus.
The aim is to help restore the normal negative pressure in the pleural space, allow the affected lung to re-expand when possible, and improve respiratory function.
NORCET point: A chest tube drains the pleural space. It is not normally inserted directly into the lung tissue.
2. Anatomy and Basic Principle
The pleural space is the potential space between:
- Visceral pleura: Covers the surface of the lungs.
- Parietal pleura: Lines the inner chest wall.
Under normal conditions, the pleural space contains a small amount of lubricating fluid and pressure that helps keep the lungs expanded. Air or excessive fluid entering this space can interfere with lung expansion.
How chest drainage works
- The tube provides a route for air or fluid to leave the pleural space.
- The drainage system helps prevent air from flowing back into the chest.
- The lung may re-expand as the underlying problem resolves.
- Respiratory status and drainage are monitored to evaluate progress.
3. Indications for Chest Tube Insertion
| Condition | Purpose |
|---|---|
| Pneumothorax | Remove air from the pleural space. |
| Tension pneumothorax | Emergency decompression is required; a chest tube may be placed after or as part of definitive management. |
| Hemothorax | Drain blood from the pleural space and monitor ongoing bleeding. |
| Pleural effusion | Drain selected clinically significant pleural fluid collections. |
| Empyema | Drain infected pleural fluid or pus as part of treatment. |
| After thoracic surgery | Remove air and fluid and support postoperative lung expansion. |
| Selected chylothorax cases | Drain chyle from the pleural space. |
4. Types of Chest Drainage Systems
A. One-bottle system
- One bottle collects drainage and acts as the water seal.
- It is a simple system but may be less suitable for larger drainage volumes.
- Changes in fluid volume can affect the water-seal depth and system function.
B. Two-bottle system
- One bottle collects fluid.
- A separate bottle provides the water seal.
- Separating collection from the water seal helps maintain the seal as fluid accumulates.
C. Three-bottle system
- Collection chamber: Collects fluid.
- Water-seal chamber: Helps prevent backflow of air.
- Suction-control chamber: Regulates suction in a traditional wet-suction system.
D. Modern commercial drainage units
Many current systems combine collection, water seal and suction control into one unit. Some use a dry suction regulator or a mechanical one-way valve rather than a traditional wet system.
5. Parts of a Chest Drainage System
| Part | Function | Nursing responsibility |
|---|---|---|
| Collection chamber | Collects pleural fluid or blood. | Measure and document the amount, color and character of drainage. |
| Water-seal chamber | Provides a one-way seal against air returning to the chest. | Maintain the prescribed water level according to the device instructions. |
| Suction-control chamber or regulator | Controls suction when prescribed. | Check the prescribed setting and device indicators. |
| Connecting tubing | Connects the chest tube to the drainage unit. | Inspect for kinks, compression, dependent loops and disconnection. |
| Chest tube | Provides access to the pleural space. | Assess insertion site, securement and dressing. |
6. Water-Seal Chamber: Important Findings
A. Tidaling (respiratory fluctuation)
Tidaling is movement of fluid in the water-seal chamber in response to changes in intrathoracic pressure during breathing.
- With spontaneous breathing, the water level commonly rises during inspiration and falls during expiration.
- With positive-pressure ventilation, the pattern may be reversed.
- Tidaling may diminish or stop when the lung re-expands or when the system or tube becomes obstructed.
- Absence of tidaling must be interpreted with the patient's condition, system type and other findings.
Exam point: No tidaling does not automatically mean the tube is blocked. Check the patient first, then inspect the system for kinks, compression or other problems.
B. Bubbling
- Intermittent bubbling: May occur as air leaves the pleural space, particularly with coughing or expiration, depending on the condition and system.
- Continuous bubbling in a traditional water-seal chamber: Suggests an air leak that requires assessment.
- Some digital or alternative systems display air-leak information differently.
- Bubbling in a wet-suction control chamber can be expected in systems designed that way; do not confuse it with bubbling in the water-seal chamber.
7. Wet Suction vs Dry Suction
| Feature | Wet suction | Dry suction |
|---|---|---|
| Control method | Uses a water column to regulate suction. | Uses a mechanical regulator. |
| Setting | Determined by the designated water level. | Set using the prescribed device control. |
| Monitoring | Observe the suction-control chamber as directed by the manufacturer. | Check the regulator indicator or device display. |
| Important principle | Use only the prescribed suction level. More suction is not automatically better. | |
8. Nursing Responsibilities Before Insertion
- Assess respiratory rate, oxygen saturation, breath sounds, blood pressure and level of consciousness.
- Explain the procedure and provide reassurance.
- Verify the order, patient identity, consent and procedural site according to policy.
- Prepare the prescribed drainage unit and required sterile equipment.
- Assist with positioning and maintain privacy.
- Establish baseline findings and ensure emergency equipment is available as appropriate.
- Administer prescribed analgesia or local anesthesia as ordered.
- Use aseptic technique and assist the clinician during insertion.
9. Nursing Care After Insertion
- Assess the patient: Monitor breathing, oxygen saturation, pulse, blood pressure, pain and breath sounds.
- Check the insertion site: Observe the dressing, securement, leakage, bleeding and subcutaneous emphysema.
- Position the drainage unit: Keep it upright and below chest level, following device instructions.
- Inspect tubing: Ensure it is not kinked, compressed, disconnected or trapped under the patient.
- Monitor drainage: Record amount, color, consistency and changes according to the clinical plan.
- Check the water seal: Confirm the correct level and observe tidaling or bubbling where applicable.
- Manage pain: Administer prescribed analgesia and reassess its effect.
- Support lung expansion: Encourage deep breathing, coughing as tolerated, mobilization and prescribed respiratory exercises.
- Document findings: Record assessments, drainage, interventions, device findings and escalation of concerns.
Daily safety checklist
- Patient's respiratory status is assessed.
- Drainage unit is upright and below chest level.
- Connections are secure.
- Tubing is free from kinks and compression.
- Drainage and device findings are documented.
- Dressing and insertion site are assessed.
- Prescribed suction and device instructions are followed.
10. Monitoring Chest Drainage
Document drainage according to local policy and the clinical condition.
- Record the amount at the specified intervals.
- Mark or record the level on the collection chamber when appropriate.
- Describe the appearance: serous, serosanguineous, bloody, cloudy or purulent.
- Compare the current amount with previous measurements.
- Report sudden increases, fresh bleeding, unexpected cessation of drainage with clinical deterioration, or any concerning change.
Important: There is no single drainage-volume threshold that is appropriate for every patient and every procedure. Escalation depends on the rate and nature of drainage, hemodynamic status, the clinical situation and the treating team's instructions.
11. Chest Tube Troubleshooting and Emergencies
| Problem | Possible meaning | Nursing response |
|---|---|---|
| Sudden severe dyspnea or desaturation | Possible tension pneumothorax, obstruction, displacement or another acute problem. | Assess the patient immediately, activate emergency support and follow the emergency protocol. |
| Continuous bubbling in water seal | Possible air leak from the patient, tubing or connections. | Inspect connections and the system according to protocol; notify the responsible clinician if persistent or concerning. |
| No tidaling | Possible lung re-expansion, obstruction, kinking or device-specific factors. | Assess the patient and inspect the system; do not assume blockage solely from this finding. |
| Tube becomes disconnected from drainage unit | Loss of the closed drainage system. | Obtain immediate help and restore a safe drainage pathway using the approved emergency protocol for that device. Do not leave the system open. |
| Tube comes out of the chest | Dislodgement with risk of air entry and respiratory compromise. | Call for urgent assistance, assess breathing and apply the institution's approved sterile occlusive dressing protocol. Do not blindly reinsert the tube. |
| Tube appears blocked or kinked | Drainage may be impaired. | Inspect visible tubing and positioning. Notify the clinician; do not strip, milk or flush the tube unless specifically ordered and allowed by protocol. |
| Sudden fresh or increasing bloody drainage | Possible bleeding or hemorrhage. | Assess vital signs and the patient, quantify drainage and urgently notify the treating team. |
| Increasing subcutaneous emphysema | Air may be tracking into tissue around the chest or neck. | Assess extent and respiratory status; escalate promptly, especially if progressive or associated with breathing difficulty. |
Emergency priority: The patient's airway, breathing and circulation come first. Do not delay emergency assessment to troubleshoot the drainage unit.
12. Critical Safety Rules
- Keep the drainage unit below chest level and upright.
- Do not routinely clamp a chest tube. Clamping can cause tension pneumothorax when an air leak is present.
- Do not clamp a tube simply to transport a patient; follow the prescribed device and transport protocol.
- Do not strip or milk the tubing routinely because this can create excessive negative pressure.
- Do not flush the tube unless specifically ordered and permitted by the device and clinical protocol.
- Do not lift the drainage unit above chest level unless a specific clinical procedure requires it under appropriate supervision.
- Secure all connections and keep the system closed.
- Follow manufacturer instructions and institutional policy for all device-specific procedures.
13. Chest Tube Removal
Removal is performed by an appropriately trained clinician when the underlying condition has improved and the relevant clinical criteria are met.
Nursing responsibilities
- Explain the procedure and provide prescribed analgesia.
- Prepare sterile dressing supplies and assist the clinician.
- Follow the prescribed breathing maneuver or timing instructions during removal.
- Apply the prescribed sterile occlusive dressing according to protocol.
- Monitor respiratory status, oxygen saturation, pain and the insertion site afterward.
- Report new dyspnea, chest pain, hypoxemia or other deterioration immediately.
- Obtain follow-up imaging when ordered.
14. Possible Complications
- Infection at the insertion site or pleural infection.
- Bleeding or injury to nearby structures.
- Tube displacement or accidental removal.
- Tube obstruction or impaired drainage.
- Persistent air leak.
- Subcutaneous emphysema.
- Recurrent or tension pneumothorax.
- Re-expansion pulmonary edema in selected circumstances after rapid re-expansion of a collapsed lung.
- Pain and reduced ability to cough or mobilize.
15. Nursing Diagnoses — Examples
- Impaired gas exchange related to altered lung expansion.
- Ineffective breathing pattern related to respiratory compromise or pain.
- Acute pain related to chest tube insertion.
- Risk for infection related to an invasive device.
- Impaired physical mobility related to pain and attached drainage equipment.
- Anxiety related to breathing difficulty and invasive treatment.
Select nursing diagnoses according to the patient's assessment and the terminology required by your curriculum.
