Pathophysiology
• The pleural space that normally separates the visceral and parietal pluerae has a thin layer of lubricating fluid separating the layers
• small negative pressure in the pleural space keeps the lung inflated
• Inspiration, the negative intrathoracic pressure increases, leading to the expansion of the lung

Pathophysiology
• The addition of blood, fluid, or air in the pleural space disrupts the normal pressure gradient and interferes with normal inspiratory-induced inflation, leading to the “collapse” of the lung

INDICATIONS FOR TT
• PTX• HTX• Empyema
![Page 6: Clinical emergency procedures Chest Tube](https://reader031.fdocuments.in/reader031/viewer/2022013102/556afb2ed8b42a2a4f8b4bbe/html5/thumbnails/6.jpg)
INDICATIONS : PTX
• Spontaneous v.s secondary • Underlying lung disease v.s normal lung status • pt stable v.s unstable . • Large v.s small PTX• Pt is for transport • Mechanism of injuries

Guidelines of the American College of Chest Physicians for the definition of a clinically stable Pateint with PNEUMOTHORAX
• A clinically stable patient must have all of the following present:
1.respiratory rate, <24 breaths/min; 2.heart rate, >60 beats/min or <120 beats/min;3. normal blood pressure, 4.room air O2 saturation, >90%; and
5.can speak in whole sentences between breaths.

Small PTX IN STABLE PT • ALL pt with penetrating thoracic injuries who
will require Transport >> TT is indicated
• Traumatic small PTX in pt who will require PPV can turn to tension PTX >> good consensus that TT is indicated

INDICATIONS : HTX• About three fourths of patients with a traumatic HTX can be
managed by TT and volume replacement alone.
• Indications for thoracotomy after TT :1. Massive hemothorax, >1000–1500 mL initial drainage 2. >200 mL/hr for first 3 or more hr 3. Increasing size of hemothorax on chest film4. Persistent hemothorax after two functioning tubes placed 5. Clotted hemothorax 6. Large air leak preventing effective ventilation 7. Persistent air leak after placement of second tube or inability to
fully expand lung

CONTRAINDICATIONS

![Page 11: Clinical emergency procedures Chest Tube](https://reader031.fdocuments.in/reader031/viewer/2022013102/556afb2ed8b42a2a4f8b4bbe/html5/thumbnails/11.jpg)
CONTRAINDICATIONS
• For unstable injured patients with a PTX or an HTX, there are no absolute contraindications to a TT
• In the stable patient, relative contraindications include anatomic problems such as the presence of multiple pleural adhesions, emphysematous blebs, or scarring. Coagulopathic patients

• Weight (kg) Chest Tube (Fr) • <3 8–10 • 3–5 10–12 • 6–10 12–16 • 11–15 17–22 • 16–20 22–26 • 21–30 26–32 • >30 32–40

TAKE HOME MASSEGE
• CLINICAL JUDGEMENT FOR INDICATIONS FOR TT
• YOU NEED TO MASTER IT ( ?? TRUMA TEAM )
• ALWAYS SECURE THEN CONFIRM YOUR TUBE PLACEMENT.
