Polytrauma
What is Polytrauma?
Polytrauma (or multiply injured patient) is a patient with traumatic injuries involving at least two body regions (head, chest, abdomen, pelvis, limbs, spine), at least one of which is potentially fatal. The vital prognosis is threatened, and mortality is directly related to the severity of the injuries as well as the speed and quality of management.
Polytrauma is the leading cause of death in people under 40 worldwide (road accidents, falls from height, work accidents). In Tunisia, our emergency departments, trauma surgery services, and intensive care units are organized as Trauma Centers according to the ATLS (Advanced Trauma Life Support) model of the American College of Surgeons.
What are the Causes and Frequent Injuries?
Main causes:
- Road traffic accidents (RTA): 60-70% (pedestrians, two-wheelers, vehicles, motorcycles).
- Falls from height: 15-25% (work, domestic, suicide).
- Work accidents (machinery, falls, crushing): 10-15%.
- Assaults with knives or firearms: 5-10%.
- Natural disasters, train accidents, air accidents: rare.
Injuries by anatomical region (frequency):
- Traumatic brain injury (TBI): 40-60% (subdural hematoma, epidural hematoma, contusions, skull fracture).
- Thoracic trauma: 30-50% (hemothorax, pneumothorax, flail chest, pulmonary contusion, sternal fracture).
- Abdominal trauma: 20-30% (laceration of liver, spleen, kidneys, pancreas, bowel perforation).
- Pelvic trauma: 15-25% (unstable fractures, retroperitoneal hemorrhage).
- Limb trauma: 40-60% (femur/tibia fractures, open fractures, dislocations).
- Spinal trauma: 10-20% (vertebral fractures, spinal cord injuries).
- Vascular injuries: 5-15% (arterial transection, thoracic aortic rupture).
What are the Signs of Polytrauma?
Polytrauma is an absolute emergency. Clinical signs vary depending on the injuries, but the general presentation is that of traumatic shock (hypovolemic, cardiogenic, or mixed) with:
- Arterial hypotension (SBP < 90 mmHg, MAP < 65 mmHg) or signs of compensated shock (tachycardia > 120/min, mottling, cold extremities).
- Altered consciousness (altered Glasgow Coma Scale, from confusion to coma).
- Respiratory distress (tachypnea, desaturation, asymmetrical breath sounds – hemothorax/pneumothorax).
- External hemorrhage (wound, hemothorax, hemoperitoneum).
- Intense pain and limb deformity.
- Signs of pelvic fracture (instability, bruising).
- Signs of neurogenic shock (if high spinal cord injury).
How is Polytrauma Managed in Tunisia?
Management follows the recommendations of the Advanced Trauma Life Support (ATLS) from the American College of Surgeons, adapted in the European version (ESTES).
Pre-hospital Phase (At the Scene)
- ABCDE protocol:
- A (Airway): airway control, early intubation if GCS ≤ 8, respiratory distress, obstruction.
- B (Breathing): ventilation, oxygen therapy (SpO2 ≥ 90-95%), decompression of tension pneumothorax (needle decompression).
- C (Circulation): vascular access (2 peripheral lines 16-18G), fluid resuscitation (crystalloids), control of external hemorrhage (compression, tourniquet), norepinephrine if refractory shock.
- D (Disability): neurological assessment (Glasgow Coma Scale, pupil size).
- E (Exposure): complete undressing, search for other injuries, hypothermia prevention (survival blanket).
- Strict cervical spine immobilization (rigid collar) and spinal immobilization (long spine board).
- Transport to a Level I or II Trauma Center (with 24/7 neurosurgery, thoracic surgery, abdominal surgery, orthopedic surgery, intensive care).
Initial Hospital Phase (Trauma Room, Code Red)
Emergency imaging (Whole Body CT – WCB):
- Whole Body CT (head, face, cervical spine, chest, abdomen, pelvis) with contrast (unless contraindicated). Performed in < 10-15 minutes.
- Standard X-rays: chest, pelvis (if CT not immediately available).
- FAST ultrasound (Focused Assessment with Sonography in Trauma): search for peritoneal or pericardial effusion. Performed in less than 5 minutes.
Emergency laboratory tests: CBC, platelets, PT/PTT (coagulation), blood group/Rh, β-HCG (women of childbearing age), electrolytes, creatinine, lactate, blood gas, blood alcohol, toxicology screen.
Damage Control Resuscitation (DCR) and Damage Control Surgery (DCS)
For patients in severe hemorrhagic shock, the Damage Control strategy is applied:
- Damage Control Resuscitation (DCR):
- Permissive fluid resuscitation (limited crystalloids, early transfusion).
- Protocolized massive transfusion (1:1:1 ratio: red blood cells / plasma / platelets).
- Administration of tranexamic acid (Exacyl®) 1g IV ≤ 3 hours post-trauma (reduces mortality).
- Correction of acidosis and hypothermia.
- Damage Control Surgery (DCS): shortened surgical procedure (less than 60-90 minutes) aimed at:
- Controlling hemorrhage (arterial ligation, abdominal packing, radiological embolization).
- Controlling digestive contamination (rapid suture, stoma).
- Draining spaces (thoracic, peritoneal).
- A second look is scheduled at 24-48 hours for definitive repairs and closure.
Specific Management by Surgical Specialty
Severe Traumatic Brain Injury (severe TBI): see TBI protocol (hematoma evacuation, ICP monitoring, decompressive craniectomy).
Thoracic Trauma:
- Chest tube (hemothorax, pneumothorax).
- Emergency thoracotomy (massive hemorrhage, cardiac wound, aortic rupture).
- Stabilization of flail chest (rib osteosynthesis).
Abdominal Trauma:
- Emergency laparotomy (hemostasis, splenectomy, hepatorrhaphy, bowel repair).
- Radiological embolization (liver, spleen, kidney).
- Damage control laparotomy (abdominal packing, temporary closure).
Pelvic Trauma:
- Pelvic binder (external stabilization).
- External pelvic fixator (surgery).
- Embolization of pelvic arteries (interventional radiology).
Limb and Spine Trauma:
- Temporary external fixator for open or unstable fractures.
- Delayed definitive osteosynthesis (after hemodynamic stabilization).
- Spinal fixation (posterior or anterior approach).
Trauma Intensive Care Management
After the surgical phase, the patient is transferred to the multidisciplinary or trauma intensive care unit. Monitoring and care include:
- Continuous monitoring: monitor, oximetry, invasive arterial pressure, CVP, cardiac output (PiCCO, Swan-Ganz).
- Mechanical ventilation: lung protection (post-traumatic ARDS is common).
- Iterative transfusions (red blood cells, platelets, plasma).
- Correction of post-traumatic coagulopathy (DIC).
- Early enteral nutrition (nasogastric tube).
- Complication prevention: pressure ulcers, deep vein thrombosis, nosocomial infections (pneumonia, catheter-related infections).
- Adapted sedation-analgesia (ventilated patients).
What are the Risks and Complications of Polytrauma?
Complications are frequent and severe:
- Massive hemorrhage and hemorrhagic shock (acidosis, hypothermia, coagulopathy – lethal triad).
- Post-traumatic coagulopathy (DIC).
- Post-traumatic Acute Respiratory Distress Syndrome (ARDS) (20-30%).
- Sepsis and multiple organ dysfunction syndrome (MODS).
- Compartment syndrome (abdominal, limbs) requiring decompressive fasciotomy.
- Fat embolism (long bone fractures).
- Infectious complications: ventilator-associated pneumonia (VAP), cerebral abscess, meningitis, osteoarticular infection, sepsis.
- Pressure ulcers, deep vein thrombosis, pulmonary embolism.
- Permanent neurological sequelae (hemiplegia, quadriplegia, cognitive disorders, vegetative state).
Prognosis of Polytrauma
Polytrauma mortality has decreased in recent decades (from 30-40% to 10-20% in expert centers), thanks to advances in damage control, imaging, and intensive care. Unfavorable prognostic factors:
- Age > 65 years (mortality tripled).
- High ISS (> 25).
- Severe traumatic brain injury (GCS ≤ 8).
- Massive hemorrhage (> 10 red blood cell units/24h).
- Prolonged shock with acidosis (pH < 7.20) and hypothermia (< 34°C).
- Severe coagulopathy (DIC).
What to Do After Polytrauma? Multidisciplinary Rehabilitation
Discharge from intensive care (duration 10 to 60 days, or more) is followed by a phase of intensive multidisciplinary rehabilitation:
- Physical and respiratory therapy: gait restoration, muscle strengthening, exercise retraining, bronchial clearance.
- Occupational therapy: relearning activities of daily living (dressing, washing, eating), home adaptation (wheelchair, medical bed, ramps).
- Speech therapy: language rehabilitation (post-traumatic aphasia), swallowing disorders (aspiration risk), cognitive-linguistic disorders.
- Neuropsychology: intensive cognitive rehabilitation (memory, attention, executive functions, planning).
- Psychologist / Psychiatrist: post-traumatic stress disorder (PTSD, 30-50% of polytrauma patients), anxiety, depression, behavioral disorders.
- Social work: disability recognition, return to work, financial aid, home adaptation.
- Surgical and orthopedic follow-up: consultations at 1, 3, 6, 12 months, control X-rays, revision of osteosynthesis, treatment of sequelae (pseudarthrosis, stiffness, infection).
