Initial Management of Trauma
The initial approach to trauma prioritizes immediate hemorrhage control, hemodynamic stabilization with restricted fluid resuscitation, and rapid transport to a Level 1 trauma center, with assessment following a structured algorithm based on hemodynamic stability. 1
Pre-Hospital Phase: Life-Saving Interventions
Hemorrhage Control (First Priority)
- Apply tourniquets immediately for life-threatening extremity bleeding before addressing airway concerns, as this is the most rapidly reversible cause of preventable death 1
- Tourniquets should remain in place until surgical control is achieved, ideally less than 2 hours 1
- For suspected pelvic trauma, apply a pelvic binder around the greater trochanters as soon as possible based on mechanism and clinical suspicion, without waiting for radiographic confirmation 1, 2
Hemodynamic Management
- Target systolic blood pressure 80-90 mmHg (MAP 50-60 mmHg) using restricted fluid resuscitation until bleeding is controlled 1
- Critical exception: In traumatic brain injury (GCS ≤8), maintain MAP ≥80 mmHg to ensure adequate cerebral perfusion 1
- Avoid large-volume crystalloid resuscitation pre-hospital—volumes >2000ml increase coagulopathy to >40% 1
Temperature and Transport
- Remove wet clothing, apply warm blankets, and shield from wind/ground contact to prevent hypothermia 1
- Transport all severe trauma patients directly to a designated Level 1 trauma center, not the nearest hospital, as this increases survival by 15-30% 1, 2
Hospital Phase: Trauma Bay Assessment
Airway and Ventilation
- Maintain normoventilation (avoid hyperventilation) unless signs of imminent cerebral herniation 1
- Never hyperventilate trauma patients routinely—this increases mortality through cerebral vasoconstriction and decreased venous return 1
Hemodynamic Assessment Algorithm
For Hemodynamically Unstable Patients (SBP <90 mmHg):
- Obtain pelvic X-ray upon arrival to identify fracture pattern 2, 3
- Perform E-FAST (Extended Focused Assessment with Sonography for Trauma) to detect intra-abdominal bleeding, hemopericardium, and pneumothorax 4, 2, 3
- E-FAST has 97% positive predictive value for intra-abdominal hemorrhage in pelvic trauma patients 2, 3
- Initiate crystalloid fluids but maintain restricted volume strategy 1
- Proceed directly to operative management or interventional radiology without CT imaging in most cases 4
For Hemodynamically Stable Patients (SBP ≥90 mmHg):
- Do NOT obtain pelvic X-ray 2
- Proceed directly to CT scan of chest, abdomen, and pelvis with IV contrast 4, 2, 3
- Contrast-enhanced CT with multiplanar reformations is the standard imaging tool due to fast acquisition and excellent resolution 4
- CT angiography can identify active bleeding with 82-89% sensitivity 2
Clinical Assessment Priorities
- Clinically assess hemorrhage using mechanism of injury, physiology, anatomical pattern, and response to resuscitation 1
- Inspect the abdomen for distension, asymmetry, laceractions, abrasions, and "seat belt sign" that may indicate intraabdominal injury 3
- Significant abdominal rigidity and involuntary guarding indicate peritonitis and suggest bowel perforation 3
- Record core temperature immediately (esophageal, bladder, or rectal—peripheral measurements unreliable) 1
Management of Specific Abdominal Trauma
Non-Operative Management
- In patients with abdominal trauma without active peritoneal bleeding or bowel perforation, non-operative management should be recommended to reduce morbidity and mortality 4
- Non-operative management is now standard of care in more than 80% of abdominal trauma when hemorrhagic shock and bowel perforation are ruled out 4
- 90% of traumatic renal injuries and 70-80% of traumatic splenic and hepatic injuries are treated non-operatively 4
Interventional Radiology
- In patients with established ongoing intraperitoneal bleeding, emergent hemostatic angio-embolization should be considered among other therapeutic options 4
- Therapeutic angio-embolization can significantly reduce the failure rate of non-operative management in splenic, hepatic, kidney, and adrenal injuries with documented active bleeding 4
- In hemodynamically unstable patients showing transient response to fluid resuscitation, transcatheter arterial embolization has demonstrated 100% success rate 4
Penetrating Trauma Considerations
- In hemodynamically stable patients with penetrating abdominal trauma without clinical signs of peritonitis or evisceration, exploratory laparoscopy is recommended after initial radiologic survey to rule out peritoneal perforation 4
- Non-therapeutic laparotomy increases hospital length of stay and carries significant risk of complications (eventration and occlusion in 10-40% of cases) 4
Critical Pitfalls to Avoid
- Never apply permissive hypotension in TBI patients—they require MAP ≥80 mmHg for cerebral perfusion 1
- Never place pelvic binders incorrectly—they must be positioned around the greater trochanters, not the iliac crests 1, 2
- Never delay binder application for radiographic confirmation—apply based on mechanism and clinical suspicion 2
- Never overlook temperature documentation—hypothermia significantly worsens outcomes 1
- Be aware that 20% of intestinal injuries are missed on initial CT scan—serial examinations are critical for non-operative management 3
