We will talk today about Trauma patient and what is the surgery resident role and duty to help this patient.
Trauma is the leading cause of death in the 1- to 45-year-old age group, and it is the fourth cause of death in the general population.
One of the most common and most serious complications in the polytrauma patient is hemorrhage.
Blood loss leads to a decreased oxygen transport to the tissues.
Hypoxemia triggers metabolic alterations that drive the body to a situation called lethal triad: acidosis, hypothermia, and coagulopathy.
Bleeding can cause hypovolemic shock. In consequence, tissues will be poorly perfused and cellular metabolism will be altered causing a metabolic acidosis.
Hypothermia: Body temperature decreases under 35 °C due to hypovolemic shock and hypoxemia.
The normal coagulation mechanism is altered by blood loss causing coagulopathy.
- In the Polytrauma patients, the defense mechanisms are activated by hypoxia, acidosis, and tissue hypoperfusion especially in the liver, kidney, and lung.
The defense mechanisms activated will led
- tachycardia (>90 bpm),
- tachypnea (>20 breath pm),
- body temperature >38.5 °C,
- and leukocytosis.
The clinical consequences of the hyper-inflammatory response are acute respiratory distress syndrome (ARDS) and multiple organ failure syndrome (MOFS).
Acute respiratory distress syndrome (ARDS): It is caused by damage of the alveolar membrane.
Which alters the gas exchange
The final result is hypoxemia and heart failure.
Multiple organ failure syndrome (MOFS): Lung damage is followed by progressive damage of other organs such as the liver, kidney, and, finally, the heart.
The initial management of the polytrauma patient goes through two phases: prehospital trauma life support (PHTLS) which is held in the crash place by emergency teams.
Triage: Patient chances of survival, therapeutic needs, and available resources.
Immediate life support:
1- Open Airway
2- Effective breathing
3- treating hypovolemic shock
4- Bleeding Control
5- Adequate immobilization
Then, patient must be taken immediately to the nearer trauma center.
Information and communication: Emergency team should obtain as much information as possible about patient medical history as well as accident characteristics.
The obtained information must be communicated to the hospital prior to the patient transfer.
and advanced trauma life support (ATLS) in the hospital.
ATLS protocol consists of three phases: primary survey (A, B, C, D, E), secondary survey, and definitive treatment of the injuries. Which I will talk about in details in this meeting.
Advanced Trauma Life Support (ATLS) in the Hospital
The poly-trauma patient management passes through three phases:
Primary Survey (A,B,C,D,E)
Secondary Survey.
Definitive treatment of injuries.
Primary survey: ABCDE protocol must be followed:
A (Airway): Patency of the airway must be checked discarding the existence of foreign bodies, facial fractures, or laryngeal or tracheal injuries.
The most common cause of airway obstruction is dropping of the tongue backward in unconscious patient.
In case of obstruction of the airway and in patients with GCS <8, endotracheal intubation or emergency cricothyroidotomy would be indicated.
B (Breathing):
- If breathing is insufficient, one of these situations should be suspected:
- Tension pneumothorax: requires immediate decompression by needle into second intercostal space midclavicular line or chest tube in 5th intercostal space.
- Flail chest: Require mechanical ventilation.
- Open pneumothorax: Treatment is airtight closure of the defect and drainage by chest tube.
Massive hemothorax: It must be drained by a thoracic tube and hemorrhage controlled.
If bleeding is greater than 1,500 cc initially or more than 200 cc/h during 2 h, exploratory thoracotomy may be necessary.
C (Circulation):
There are four parameters to assess:
consciousness
skin color
Temperature
pulse, and blood pressure
If they are altered, hypovolemic shock should be suspected.
The main cause of hypovolemic shock is severe hemorrhage so we must look for bleeding points.
Hemorrhage may be:
- External hemorrhage: Especially in limbs. They can be controlled by hemostatic forceps or tourniquet.
Internal or hidden hemorrhage: They used to be in thoracic, abdominal, or pelvic cavities.
We must suspect its existence in all patients with hypovolemic shock and no visible bleeding.
In all patients with hypovolemic shock, two peripheral veins should be channeled, and then volume replacement will be introduced administering crystalloid liquids (ringer lactate) and isogroup blood.
D (Disability): neurological evaluation exploring the level of consciousness, motor focality, and size and reactivity of pupils.
The Glasgow Coma Score (GCS) is an excellent method to establish the neurological status in a simple and fast way.
E (Exposure): The patient should be completely naked for proper exploration.
However, we must be careful to avoid hypothermia so the emergency room shall be maintained at a suitable temperature, the patient should be covered
and intravenous fluids should be warmed before administration.
General Information
- Secondary survey is a head-to-toe evaluation of the trauma patient ⇒ a complete history, physical examination, and reassessment of all vital signs
If additional personal are available, part of the secondary survey may be conducted while the other personnel attend to the primary survey
This should NOT interfere with the primary survey which is highest priority
History
Complete history about mechanism of injury;
Prehospital personnel and family may assist with the history if the patient has difficulty in reporting details
Allergies
Medications used
Past illnesses/Pregnancy
Last meal
Events and environment related to the injury
Physical Examination
Head
Secondary survey begins with evaluating the head to identify all related neurologic injuries
Examine entire scalp for lacerations, contusions, and evidence of fractures
- Examine the eyes for:
Visual acuity
Pupillary size
Hemorrhage of conjunctiva and/or fundi
Penetrating injury
Contact lenses (remove before edema occurs)
Dislocation of the lens
Ocular entrapment
- If head injury
Glasgow Coma Score (GCS),
GCS of ≤ 8: severe head injury
GCS of 9-12: moderate head injury
GCS of 13-15: minor head injury
Maxillofacial structures
Palpate bony structures
Assess for occlusion
Intraoral examination
Assess soft tissues
Maxillofacial trauma not associated with airway obstruction/major bleeding should only be treated after vitals stabilization and life-threatening injuries have been managed
Cervical Spine and Neck
For patients who are wearing any type of protective helmet, extreme care must be taken when removing the helmet
Chest
+Palpate entire chest cage including the clavicles, ribs, and sternum
Tenderness may indicate fracture or costochondral separation
Significant chest injury can present with pain, dyspnea, and hypoxia.
Abdomen and Pelvis
Abdominal injuries:
A normal initial exam of the abdomen DOES NOT exclude significant intrabdominal injury
Therefore, close observation and frequent reevaluation of the abdomen by the same observer is important.
Early involvement of a surgeon is beneficial
Consider DPL (Diagnostic peritoneal lavage), abdominal ultrasonography, or CT in patients with:
Unexplained hypotension & Neurologic injury
Pelvic fractures:
Apply a pelvic binder to limit blood loss from pelvic fractures
Perineum, Rectum, and Vagina
Examine perineum for contusions, hematomas, lacerations, or urethral bleeding
Adjuvants to Secondary Survey
Draw trauma labs
CBC/FBC
Blood type and match
ABG
Imaging (e.g., C-spine, CXR, pelvis X-rays)
Tetanus prophylaxis for any lacerations or penetrating injuries
Prophylactic IV antibiotics for all open fractures or abdominal penetration
If patient remains hypotensive despite fluid and blood replacement, consider immediate abdominal or thoracic exploration.
Mechanism of injury
Blunt trauma
Interpersonal violence
Automobile collision, injuries related to transportation, recreation, and occupations.
Penetrating trauma
Gunshot wounds, stab wounds, interpersonal violence, blast debris: find out about:
- Body region that was injured
- Organs in the path of the penetrating object
- Velocity of the missile
Thermal injury
- Burns:
Serious trauma that can occur isolated or in conjunction with blunt and/or penetrating trauma
Burning automobile
Explosion
Falling debris
Patients attempt to escape a fire
Complications:
1- Inhalation injury
2- Carbon monoxide poisoning
3- Combustion and inhalation of toxic plastic and chemicals
- Hypothermia
Acute/chronic hypothermia without adequate protection can produce local or generalized cold injuries
Significant heat loss can occur:
At moderate temperatures (15°C to 20°C or 59°F to 68°F)
Wet clothes, suppressed body activity, and/or vasodilation caused by alcohol or drugs compromising the patient's ability to conserve heat
Temperature extremes
Hazardous Environment
Exposure to chemicals, toxins, and radiation
Poly-Trauma patient is presented to your ER in two states 1- Conscious.
2- Comatose.
and we will talk about how to deal with each state.
