Q & A

  • What is the primary goal of the primary survey in trauma management?

    -The primary goal of the primary survey in trauma management is to identify life threats quickly and provide stabilization when life threats are identified.

  • What are the two main components of the primary survey?

    -The two main components of the primary survey are simultaneous assessment and treatment of the patient to ensure they remain stable and that life threats are quickly addressed.

  • What is the correct order for conducting the primary survey?

    -The primary survey follows the order of airway, breathing, circulation, disability, and lastly, exposure of the patient and assessment of the environment.

  • How can you initially assess a patient's airway?

    -You can initially assess a patient's airway by speaking to them, asking their name, and getting them to tell you what happened to them. Any patient who is able to talk by definition has a patent airway.

  • What are some signs that suggest potential future airway obstruction?

Keywords
💡Primary Survey
The primary survey is a systematic and standardized approach to the initial assessment of trauma patients, aimed at quickly identifying and addressing life-threatening issues. It is the first step in trauma management and includes evaluating the airway, breathing, circulation, disability, and exposure of the patient. The script emphasizes the importance of conducting the primary survey consistently to ensure nothing is missed, as it sets the foundation for further patient care and treatment.
💡Airway
Airway refers to the pathway through which air enters and leaves the lungs. In the context of trauma management, ensuring a patent or clear airway is critical to prevent respiratory distress or failure. The script discusses the need to assess the patient's ability to speak, look for signs of swelling or bleeding that could indicate potential airway obstruction, and the importance of cervical spine immobilization during airway management.
💡Breathing
Breathing assessment is a crucial component of the primary survey, focusing on evaluating the patient's respiratory function. This involves listening for equal bilateral breath sounds, assessing respiratory effort, and monitoring the respiratory rate and oxygen saturation. The script highlights that pulmonary injuries are more common than airway injuries in trauma and that identifying and treating life-threatening pulmonary conditions like tension pneumothorax is essential.
💡Circulation
Circulation in the trauma context refers to the assessment and maintenance of the patient's blood flow and perfusion. It involves evaluating the patient's appearance, capillary refill, peripheral pulses, and blood pressure to determine the adequacy of blood circulation. The script emphasizes the commonality of hemorrhagic shock in trauma patients and the need for prompt identification and treatment of circulatory life threats.
💡Disability
Disability in the trauma assessment context refers to the evaluation of the patient's neurologic status, which includes their level of consciousness and potential brain or spinal cord injuries. The Glasgow Coma Scale (GCS) is commonly used for this assessment. The script underscores the importance of checking for signs of head or neck trauma, pupil response, and extremity movement to identify any neurologic impairment.
💡Exposure
Exposure in trauma management involves undressing the patient to conduct a thorough head-to-toe examination, ensuring that no injuries are missed. The script stresses the importance of this step in the primary survey, as it allows for a comprehensive assessment of the patient's condition. However, it also cautions against the risk of hypothermia, advising that the patient should be covered promptly after the examination to maintain body temperature.
💡Life Threats
Life threats in the context of the video refer to immediate, potentially fatal conditions that require prompt identification and treatment during the primary survey of trauma patients. These include, but are not limited to, airway obstruction, severe respiratory distress, hemorrhagic shock, and significant neurologic impairment. The script emphasizes the need to quickly address these life threats to stabilize the patient and prevent further deterioration.
💡Tension Pneumothorax
Tension pneumothorax is a life-threatening condition where air accumulates in the pleural space around the lungs, leading to increased pressure that can collapse the lung and shift the mediastinum, impairing heart and lung function. In trauma management, it is a common and serious pulmonary injury that requires immediate intervention, such as needle decompression or chest tube placement.
💡Cardiac Tamponade
Cardiac tamponade is a medical emergency where blood or fluid accumulates in the pericardial sac surrounding the heart, leading to compression of the heart and impeding its ability to fill and pump blood effectively. In the context of trauma, it is a form of obstructive shock that requires prompt recognition and treatment, often through pericardiocentesis or surgical intervention.
💡Hypothermia
Hypothermia is a condition where a person's body temperature drops below the normal range, which can lead to serious complications including coagulopathy and exacerbation of bleeding, particularly in trauma patients. The script advises against exposing the patient to the environment without measures to prevent heat loss, highlighting the importance of maintaining body temperature during assessment and treatment.
💡Glasgow Coma Scale (GCS)
The Glasgow Coma Scale is a neurological assessment tool used to evaluate a person's level of consciousness after a brain injury. It assesses three components: eye opening, verbal response, and motor response, with a maximum score of 15 indicating normal consciousness and a lower score indicating severe impairment. The script mentions the GCS as the most common method for formally assessing a trauma patient's neurologic status.
Highlights

Management of trauma begins with a primary survey, which is a standardized way of performing the initial assessment of all trauma patients.

The primary survey has two major goals: to identify life threats quickly and to provide stabilization when life threats are identified.

The primary survey follows the same order every time: airway, breathing, circulation, disability, and lastly, exposure of the patient and assessment of the environment.

When assessing the airway, it's important to identify current airway obstruction and risks for potential future airway obstruction.

Patients with a significantly depressed GCS (Glasgow Coma Scale) may require definitive airway management in the form of intubation.

Signs of significant airway injury include an inability to speak or difficulty speaking, which may necessitate emergent intubation.

While assessing the airway, it's crucial to consider the cervical spine and immobilize it in trauma patients to prevent further injury.

In trauma patients, burns can cause airway edema and inhalational injury, leading to lung damage and potential hypoxia.

Tension pneumothorax is the most common and serious pulmonary life threat in the trauma setting, but pulmonary injuries are more common than airway injuries.

When assessing a patient's breathing, listen for equal bilateral breath sounds, observe respiratory effort, and monitor oxygen saturation.

For patients with compromised breathing, initiate supplemental oxygen and emergency treatment for life-threatening pulmonary injuries.

Circulatory insufficiency is common in trauma, often due to significant blood loss. Assess the patient's overall appearance, capillary refill, and peripheral pulses.

In cases of circulatory compromise, apply direct pressure to control bleeding, ensure adequate IV access, and initiate fluid resuscitation with isotonic crystalloid.

Other causes of shock besides hemorrhage, such as tension pneumothorax and cardiac tamponade, should also be considered in trauma patients.

The disability assessment involves formally assessing the patient's level of consciousness using the Glasgow Coma Scale or the abbreviated AVPU scale.

Neurologic life threats in the primary survey include penetrating cranial injury, intracranial hemorrhage, and high spinal cord injuries.

For patients with significant neurologic disability, emergent cranial imaging, typically a non-contrast head CT, is necessary once the patient is stable from an ABC perspective.

Exposing the patient and completing a head-to-toe exam is crucial for not missing any injuries, but hypothermia should be avoided.
