,TRAUMA (MULTI-SPECIALITY) APPROACH PRIMARY SURVEY (ABCDE) AND RESUSCITATION
ADVANCED TRAUMA LIFE SUPPORT ALGORITHM 1. AIRWAY ASSESSMENT WITH CERVICAL SPINE CONTROL
- Ascertain pathway
TRAUMA DEATHS (TRIMODAL DISTRIBUTION): (1) Foreign Bodies, (2) Facial/Mandibular #, (3) Laryngeal/Tracheal #
- Immediate death occurring at time of injury – i.e. due to devastating wounds/lacerations - Assess for airway obstruction
- Early death occurring within the 1st few hours of injury – i.e. tension pneumothorax, blood loss, IC bleed Engage the patient in conversation – a patient who cannot respond verbally is
- Late death occurring days / weeks after initial injury – i.e. 20 complications – sepsis, ARDS, SIRS, MOF
assumed to have an obstructed airway till proven otherwise
(1) stridor, (2) retractions, (3) cyanosis
MAIN PRINCIPLES:
- Establish a patient airway
- Treat greatest threat to life first
Jaw Thrust – displace tongue anteriorly from the pharyngeal inlet relieving
- Definitive diagnosis is less important
obstruction
- Time is important – the “golden hour” after trauma is when 30% of trauma deaths occur, and

o Drugs – short acting sedative or hypnotic agent (i.e. etomidate
0.3mg/kg IV or midazolam 1-2.5mg IV) and paralytic agent
administered immediately after the sedative (succinylcholine 1-
1.25mg/kg IV or rocuronium 0.6-0.85mg/kg IV)
o ETT tube inserted through vocal chords and adequacy of ventilation is
assessed
b. Needle Cricothyroidectomy with jet insufflation of the airway
c. Surgical Cricothyroidectomy

The haematocrit value is not immediately altered with acute haemorrhage – it should not be an indicator of circulating blood
volume in trauma patients. Serial haematocrit values, however, may give an indication of on-going blood loss.

- Central Nervous System
Frequent re-evaluation
Prevent secondary brain injury
Imaging as indicated
Early neurosurgical consultation
GENERAL
- Have a high index of suspicion for injuries to avoid missing them (frequent re-evaluation)
- Rapidly recognise when patient is deteriorating (continuous monitoring)
- Any rapid decompensating by the patient should initiate a return to the primary survey
- In penetrating trauma, all entry and exiting wounds must be accounted for
- IV analgesia as appropriate for pain management
7
,ABDOMINAL TRAUMA CT SCAN
- All penetrating injuries below the nipple line should be suspected of entering the abdominal - Only suitable for stable patient as quite long time involved in imaging with only patient in the
cavity room risk of rapid decompensation
- All multiple trauma patients with hypotension are assumed to have intra-abdominal injuries till
proven otherwise - Advantages
Able to precisely locate intra-abdominal lesions preoperatively
TYPES OF INTRA-ABDOMINAL INJURY IN BLUNT TRAUMA Able to evaluate retroperitoneal injuries
- Solid organ injury: spleen, liver – bleeding (may be quite massive) Able to identify injuries that can be managed non-operatively
- Hollow viscus injury with rupture Not invasive
- Vascular injury with bleeding
- Disadvantages
INDICATIONS FOR IMMEDIATE LAPAROTOMY Expensive, time required to transport patient, use of contrast
1. Evisceration, stab wounds with implement in-situ, gunshot wounds traversing abdominal cavity
2. Any penetrating injury to the abdomen with haemodynamic instability or peritoneal irritation DIAGNOSTIC PERITONEAL LAVAGE (DPL) – RARELY DONE
3. Obvious or strongly suspected intra-abdominal injury with shock or difficulty in stabilising - Sensitivity of 97-98% with a 1% complication rate
haemodynamics - Useful in hypotensive, unstable patient with multiple injuries as a mean of excluding intra-
4. Obvious signs of peritoneal irritation abdominal bleeding
5. Rectal exam reveals fresh blood - Involves an incision in the midline, below umbilicus, dissection down to peritoneum a
6. Persistent fresh blood aspirated from nasogastric tube (oropharyngeal injuries excluded as catheter is placed and a litre of N/S is run into the peritoneal cavity bag is then planed on
source of bleeding) floor and allowed to fill
7. X-ray evidence of pneumoperitoneum or diaphragmatic rupture - All patients undergoing DPL require prior evacuation of the stomach via NG tube as well as
drainage of bladder by indwelling catheter
INVESTIGATIONS (IN THE ABSENCE OF THE ABOVE INDICATIONS) - Absolute Contraindication: indication for laparotomy already exists
- If patient is stable: FAST and/or CT scan - Involves making a cut in the infraumbilical region and inserting a catheter into the peritoneal
- If patient is unstable: FAST and/or DPL cavity, aspirate, then instillation of saline (1000ml) and re-aspiration
FOCUSED ASSESSMENT WITH SONOGRAPHY IN TRAUMA (FAST) - Positive DPL in setting of blunt abdominal trauma and (penetrating trauma)
- Rapid, reproducible, portable and non-invasive bedside test to detect fluid in the abdomen or Frank blood (>10ml) or any enteric contents
pericardium (≥ 100ml and more typically 500ml of peritoneal fluid, sensitivity: 60-95%) RBC >100,000 per mm3 (penetrating: > 10,000 RBC)
- Fails to identify injury to hollow viscus and to reliably exclude injury in penetrating trauma WBC >500 per mm3 (penetrating: > 50 WBC)
- Ultrasonography evaluation of four windows:
1. Subxiphoid: Pericardium
2. RUQ: Perihepatic Space (aka. Morrison’s Pouch or hepatorenal recess)
3. LUQ: Perisplenic Region (splenorenal recess)
4. Pelvis: Pouch of Douglas (suprapubic window)
5. (eFAST) – add b/l anterior thoracic sonography – detect pneumothorax
- Disadvantages
Does not image solid parenchymal damage, retroperitoneum, diaphragmatic defects or
bowel injury
Compromised in uncooperative, agitated patient, obesity, substantial bowel gas,
subcutaneous air
Less sensitive, more operator-dependent than DPL and cannot distinguish blood from ascites
Intermediate results require follow-up attempts or alternative diagnostic tests

,CARDIOTHORACIC TRAUMA
There are 5 clinical scenarios in chest trauma where bedside procedures are lifesaving: cardiac tamponade, airway
obstruction, flail chest, hemothorax, and pneumothorax.
Clinical features
Chest trauma and hypotension
Beck’s triad (hypotension, muffled heart sounds, distended neck veins) – only in 50% of
cases as hypo-vol. may prevent neck vein distension; muffled heart sounds least reliable
Pulseless electrical activity
Kussmaul’s signs (increased neck distension during inspiration, pulsus paradoxus)
Diagnostic clues
Enlarged cardiac shadow in CXR (globular heart – very rarely seen)
Small ECG voltages, electrical alternans = alternation of QRS complex amplitude or axis
between beats.
2DE – separation of pericardial layers detected (fluid exceeds 15-35ml); early diastolic
collapse of RV wall (tamponade)
Management
Aggressive fluid resuscitation – helps maintain cardiac output and buys time. *ACC/AHA definition for low QRS voltage is amplitude <5mm in standard limb leads or

Management:
Ensure adequate oxygenation, establish 2 large bore IV access and fluid resuscitation

, PNEUMOTHORAX
(TENSION/ OPEN)
Tension pneumothorax = develops when air is trapped in the pleural cavity under positive
pressure, displacing mediastinal structures and compromising cardiopulmonary function
It is a clinical diagnosis (CXR will only delay treatment, and may cause death) – signs of
pneumothorax, hypotension, neck vein distension, severe respiratory distress
Decreased venous return caused by compression of the relatively thin walls of the atria
impairs cardiac function. The inferior vena cava is thought to be the first to kink and
restrict blood flow back to the heart. It is most evident in trauma patients who may be
hypovolemic with reduced venous blood return to the heart.
Management
Needle thoracotomy: 14G needle, 2nd IC space in the midclavicular line
Followed by tube thoracotomy at the 5th IC space between anterior and mid-axillary line.
(triangle of safety: lateral border of the pectoralis major medially, a line just anterior to
the mid-axillary line laterally, and the upper border of the fifth rib inferiorly)*
Open pneumothorax occurs in a large chest wall defect with equilibration between
intrathoracic and atmospheric pressure, producing a “sucking chest wound”.
Cover defect with a sterile dressing, taping it down on 3 sides to produce a flutter-valve
effect, letting air out of the pleural cavity but not back in
Insert chest tube (not through the wound)
* If possible (provided no cervical spine injury is suspected) the patient is sat up at 45deg and the hand is placed behind their neck
on the affected side to expose the field and open up the intercostal space. The area is prepared with antiseptic and draped. LA is
infiltrated into the skin, sub-cut tissues and down to the pleura. A 2 cm transverse incision is made in 5 th IC space (aiming above the
rib as the IC NVB sits in the groove just below the rib). Blunt dissection is then performed down to the pleura with a pair of forceps
which then are pushed through the pleura into the pleural space. A finger is placed in the hole and swept around to free any
adhesions and create the space for the tube. A chest drain is inserted using a pair of forceps; usually French gauge 24–28 (if a
hemopneumothorax exists, a larger tube size, Fr. 38, is usually used). The drain is fixed with a stitch and a purse-string or mattress
suture is placed in the wound (to allow it to be closed when the drain is removed). The chest drain is connected to an underwater
seal (this allows air to escape during expiration, but no air to enter on inspiration). Ensure that the underwater seal is below the
level of the patient, otherwise the water will enter the chest. Re-X-ray the patient after the procedure to ensure correct positioning
of the tube.
