Managing Life-Thereatening Thoracic Injuries

Injury Diagnosis Therapy

Ventilator Compromises

1. Tracheobronchial disruption  Hypoxia + inability to move air

 Chest does not move with ventilation

 Hemoptysis, subcutaneous emphysema / keduanya

 Intube over a flexible bronchoscope

 Perform tracheostomy

2. Open pneumothorax (sucking chest wound)

 Hypoxia + chest wound  Sound of air passing in-out

though wound

 Apply occlusive dressing (vaseline gauze + sponge)  Insert chest tube at site remote

from wound* 3. Flail chest  Hypoxia and impaired

ventilation

 Paradoxical chest movement  Multiple rib fractures

(confirmed on roentgenogram)

 Is respiration compromises Yes: perform endotracheal intubation

No: Observe patient and control pain

Circulatory and Ventilatory Compromise

4. Tension pneumothorax  Respiratory distress (cyanosis is a later finding)

 Unilateral absence of breathing sounds  Distended neck veins

common*

 Tracheal deviation to opposite side

 Hypotension ay be present

 Insert 18-gauge needle into second interspace at

midclavicular line

 Insert chest tube into fifth interspace if air escapes or if patient improves with needle insertion

Fakultas Kedokteran Universitas Warmadewa 2009 | IB Suryadi Putra Dwipayana [0970121023] 38

5. Massive hemothorax  Respiratory distress and hypotension

 Dec. breath sounds + dullness to percussion

 Diagnosis confirmed on roentgenogram

 Replace volume  Insert chest tube*

Circulatory Compromise

6. Cardiac tamponade  Shock + cyanosis  Distended neck veins*

 Bilateral breath sounds present

 Perform percardiocentesis for temporary therapy

 Perform thoracotomy for definitive therapy

7. Aortic disruption  History of blunt trauma  Suspicious chest

roentgenogram

 Aortography is diagnostic (computed axial tomographic scan less sensitive)

 Repair during operation

8. Myocardial contusion  Hypotension, dysrhythmia, or both are most common  Echocardiogram,

electrocardiograms, cardiac enzymes

 What is the patient‟s response?  What are the pitfalls?

Shock

 Inadequate organ perfusion

 Inadequate substrate delivery  Anaerobic metabolism  Celular dysfunction  Cell death

How do you recognize it?

 Scene information/mechanism of injury  Physical examination

o Tachycardia

o Alteration in Conciousness o Cold, diaphoretic skin o  Urinary output o Hypotension o Tachypnea

Recognition of Shock State 1. Tachycardia

2. Vasoconstriction 2.  Cardiac output Narrow pulse pressure 3.  Map

3.  Blood Flow
