In the high-stakes world of trauma care, the ability to quickly and effectively assess and manage patients is crucial. Central to this training are the Primary and Secondary Surveys, which ensure that immediate life-threatening conditions are identified and treated promptly, followed by a thorough examination to uncover all injuries. Whether you are a medical student, an emerging trauma professional, or someone interested in emergency medicine, understanding these surveys is essential for delivering comprehensive and effective patient care. In this article you will learn everything about Primary and Secondary Surveys in ATLS - advanced trauma life support.
What is a Primary Survey in ATLS? ⛑️
The Primary Survey is a systematic approach used in trauma care to identify and manage life-threatening injuries rapidly. The goal is to quickly assess and stabilize the patient by addressing the most critical issues first. This initial assessment is crucial because it ensures that no immediate threats to life are missed.
How is the Primary Survey Administered? ⛑️
The Primary Survey is conducted using the DRABC mnemonic, which stands for Danger, Response, Airway, Breathing, and Circulation. This method ensures a structured and thorough assessment.
Meaning and Use of DRABC ⛑️
Danger
🚨 Identify Hazards: Ensure the environment is safe for both the patient and the healthcare providers.
🚨 Remove Threats: Address any immediate dangers, such as fire, electrical hazards, or unstable structures.
Response
🚨 Assess Responsiveness: Determine the patient's level of consciousness using the AVPU scale (Alert, Voice, Pain, Unresponsive).
🚨 Check for Responsiveness: Gently shake the patient or call out to them to see if they respond.
Airway
🚨Clear the Airway: Ensure no obstructions such as vomit, blood, or foreign objects exist.
🚨 Protect the Cervical Spine: Assume all trauma patients have a cervical spine injury until proven otherwise, using immobilization techniques.
Breathing
🚨 Assess Breathing: Look, listen, and feel for chest movement, breath sounds, and rate.
🚨 Provide Oxygen: Administer high-flow oxygen to all trauma patients.
🚨 Support Ventilation: Use a bag-valve mask if necessary and be prepared for advanced airway management if breathing is inadequate.
Circulation
🚨 Check Circulation: Assess pulse rate, blood pressure, capillary refill, and skin color.
🚨 Control Bleeding: Apply direct pressure to wounds and use tourniquets if necessary.
🚨 IV Access and Fluids: Establish intravenous access and administer fluids to maintain blood pressure and perfusion.
Tips for Conducting a Primary Survey
🩺 Stay Calm and Focused: Keep a clear head to ensure a thorough and systematic assessment.
🩺 Practice Consistently: Use the DRABC method in all trauma situations to build muscle memory.
🩺 Communicate Clearly: Relay findings and actions to your team efficiently.
What is a Secondary Survey in ATLS? ⛑️
The Secondary Survey is a comprehensive head-to-toe examination conducted after the Primary Survey. Its purpose is to identify all injuries, not just the immediately life-threatening ones. This survey allows for a detailed assessment of the patient's condition.
When Should the Secondary Survey Be Completed? ⛑️
The Secondary Survey should be completed once the patient is stabilized and immediate life-threatening conditions have been addressed. This typically follows the Primary Survey and initial interventions.
Main Parts of the Secondary Survey ⛑️
The Secondary Survey consists of two main components: History and Physical Exam.
History --> Using the AMPLE Mnemonic
Allergies: Identify any known allergies to medications, foods, or environmental factors.
Medications: Document current medications, including prescriptions, over-the-counter drugs, and supplements.
Past Medical History: Record relevant medical history, including previous surgeries and chronic conditions.
Last Meal: Note the time and content of the patient's last meal, important for surgical considerations.
Event History: Gather details about the events leading up to the injury, including the mechanism of injury.
How to Conduct a Physical Exam
Start at the patient's head and work your way down the body. This systematic approach ensures that no area is overlooked.
Head and Face
🥼 Check for lacerations, bruising, and deformities.
🥼 Examine the eyes, ears, nose, and mouth for bleeding or foreign objects.
🥼 Assess pupils for size, equality, and reaction to light.
Neck
🥼 Look for signs of trauma, such as bruising or swelling.
🥼 Palpate for tenderness and deformities.
🥼 Ensure the cervical spine is protected.
Chest
🥼 Inspect for injuries, asymmetrical movement, or deformities.
🥼 Auscultate breath sounds, and heart sounds.
🥼 Palpate for tenderness, crepitus, or instability.
Abdomen
🥼 Inspect for distension, bruising, or penetrating injuries.
🥼 Palpate all quadrants for tenderness, rigidity, or masses.
🥼 Percuss and auscultate bowel sounds.
Pelvis
🥼 Inspect for signs of trauma.
🥼 Gently compress the pelvis to check for stability.
🥼 Assess for bleeding or deformities.
Extremities
🥼 Inspect for wounds, deformities, or swelling.
🥼 Palpate for tenderness and check for pulses.
🥼 Assess motor and sensory function.
Back
🥼 Log-roll the patient while maintaining spinal precautions.
🥼 Inspect and palpate for injuries.
Tips for Conducting a Secondary Survey ⛑️
🩺 Be Thorough: Take your time to ensure no injuries are missed.
🩺 Document Findings: Record all observations meticulously.
🩺 Communicate with the Patient: Keep the patient informed and reassured throughout the process.
Practical Advice for ATLS Students ⛑️
🩺 Regular Practice: Participate in simulations and practical exercises to build confidence and competence in performing surveys.
🩺 Team Coordination: Work closely with your team, ensuring everyone is aware of their roles and responsibilities.
🩺 Continuous Learning: Stay updated with the latest guidelines and research in trauma care.
Common Pitfalls to Avoid ⛑️
🩺 Rushing Through: Avoid the temptation to hurry through the surveys. Thoroughness is crucial.
🩺 Ignoring Non-life-threatening Injuries: Even minor injuries can have significant consequences if overlooked.
🩺 Poor Communication: Clear, concise communication with your team is essential for effective trauma management.
