Algorithm Steps

  1. Start

    Suspected Thoracic Injury

    Chest trauma with respiratory/circulatory compromise

    1. Decision

      Signs of Tension Pneumothorax?

      Clinical diagnosis - immediate treatment

      • Severe respiratory distress
      • Hypotension/tachycardia (obstructive shock)
      • Tracheal deviation (late sign)
      • Absent breath sounds on affected side
      • Distended neck veins (JVD)
      • DO NOT DELAY FOR IMAGING
      1. Warning

        IMMEDIATE Needle Decompression

        Life-saving intervention

        • Site options:
        • • 2nd ICS, midclavicular line (traditional)
        • • 5th ICS, anterior axillary line (preferred - thinner)
        • 14-16 gauge needle, ≥8cm length adults
        • Insert perpendicular to chest wall
        • Rush of air confirms diagnosis
        • Leave catheter in place
        1. Action

          Definitive: Chest Tube

          Follow needle decompression with tube thoracostomy

          • 5th ICS, anterior to mid-axillary line
          • Tube size: 28-32 Fr (hemothorax), 24-28 Fr (pneumothorax)
          • Connect to underwater seal/Pleur-evac
          • Confirm placement with CXR
          1. Decision

            Massive Hemothorax?

            Indications for thoracotomy

            • >1500mL immediate drainage
            • >200mL/hr for 2-4 hours
            • Continued transfusion requirement
            • Persistent shock despite resuscitation
            1. Warning

              OR for Thoracotomy

              Surgical exploration indicated

              • Notify OR and thoracic/trauma surgery
              • Continue resuscitation en route
              • Prepare for autotransfusion if available
              1. Outcome

                Thoracic Injury Managed

                Lung re-expanded, hemodynamically stable

            2. Action

              Monitor & Manage

              Standard post-procedure care

              • Confirm tube position with CXR
              • Monitor output and air leak
              • Pain control (intercostal blocks, PCA)
              • Incentive spirometry
              • Consider removal when <150mL/24h, no air leak
      2. Decision

        Open (Sucking) Chest Wound?

        Visible chest wall defect

        1. Action

          3-Sided Occlusive Dressing

          Or vented chest seal

          • Apply occlusive dressing (petroleum gauze)
          • Tape on 3 sides (valve effect)
          • Or use commercial vented chest seal
          • Prepare for chest tube placement
          1. Action

            Chest Tube Insertion

            Tube thoracostomy technique

            • Position: supine, arm abducted 90°
            • Site: 5th ICS, between ant/mid-axillary line
            • Incision over rib, blunt dissect over superior border
            • Finger sweep pleural space
            • Direct tube posteriorly and superiorly
            • Connect to drainage system, secure with suture
        2. Decision

          Simple Pneumothorax/Hemothorax

          Stable patient, imaging obtained

          • CXR or CT shows pneumothorax/hemothorax
          • No tension physiology
          • Assess size and symptoms
          1. Action

            Small Pneumothorax (<2cm)

            Observation may be appropriate

            • Stable, asymptomatic: observe 6h, repeat CXR
            • Supplemental O2 (accelerates reabsorption)
            • If stable on repeat: discharge with follow-up
            • If symptomatic or progressing: chest tube
          2. Action

            Large Pneumothorax/Hemothorax

            Chest tube indicated

            • >2cm pneumothorax
            • Symptomatic (dyspnea, hypoxia)
            • Hemothorax >300-500mL
            • Positive pressure ventilation planned
            • Associated rib fractures

Clinical Safety Information

Clinical Decision Support — Not a Substitute for Clinical Judgment

Individual patient factors may require deviation from these recommendations.

Known Limitations

  • Clinical diagnosis - do not delay treatment for imaging
  • Needle decompression is temporizing, not definitive
  • Chest wall thickness varies - may need longer needle
  • Pediatric sizes differ

Applicable Regions

US: 5th ICS AAL increasingly preferred for needle decompression
