Management of Suspected Chest Tube Malpositioning

Initial Diagnostic Approach

• Obtain a portable chest radiograph as the first-line imaging modality to assess chest tube position after insertion, as approximately 10% of chest tubes are malpositioned on initial post-insertion radiographs 1

Clinical Assessment of Tube Function

• Sudden cessation of drainage should prompt evaluation for tube obstruction or malposition, and check for tube kinking, especially with small soft drains in mobile patients 2
• Assess the respiratory swing of fluid in the chest tube to confirm proper positioning in the pleural cavity, as absence of respiratory swing may indicate extrapleural positioning or complete lung re-expansion 2

Critical Safety Considerations

• Never clamp a bubbling chest tube, as this can cause fatal tension pneumothorax, and keep the drainage system below the patient's chest level at all times, and manage patients with chest tubes on specialized wards with trained staff, and if air leak persists beyond 4 days, consider surgical evaluation 2

Ongoing Monitoring

• Continue monitoring with serial chest radiographs to ensure ongoing effectiveness when intrafissural or minor malpositions without evidence of clinical malfunction are observed and drainage is adequate 1
