Initial Assessment of the Trauma Patient
ObjectivesIdentify and treat immediately life-threatening injuries in the correct priority sequenceEstablish needed resuscitative measures to then allow a complete secondary survey to be conductedAllow triage decisions to be made when there are multiple simultaneous patients

Proper Trauma Care Sequence
Initial Assessment : Rapid Primary Survey
Start resuscitation measures Detailed secondary survey Diagnostic studies Re-evaluate the patient at frequent
intervals Decide on patient disposition and
definitive care
![Page 4: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/4.jpg)
Basic Principle of Initial Assessment
Correction of life-threatening emergencies (resuscitation) must be done simultaneously with the primary survey
Treatment takes precedence over diagnosis
![Page 5: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/5.jpg)
Communication Between Prehospital Personnel and the Emergency Department
Patient care is improved when there is good communication from prehospital personnel to the E.D.
Radio or phone reports on trauma patients should be brief (< 45 seconds), and should be given as soon as possible before arrival in the E.D.
![Page 6: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/6.jpg)
What Information Should be Relayed in the Prehospital Care Report ?
Number of victims and their ages and gender Mechanism of injury Suspected injuries Vital signs Treatment measures started Estimated time of arrival ( "E.T.A." ) Any special precautions for the E.D.
Hazardous materials contaminationCombative patient or accompanying persons
![Page 7: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/7.jpg)
Preparation of the E.D. to Receive a Major Trauma Victim
Collect adequate E.D. personnel Clear a bed or room for the victim Obtain and arrange :
Airway equipment, IV fluid bags and lines, bandages, chest tubes and waterseal bottles, blood units from the blood bank ( O-negative )
Alert ancillary personnelX-ray, laboratory, respiratory therapy, special nursing units, security
![Page 8: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/8.jpg)
Preparation of the E.D. to Receive a Major Trauma Victim (cont.)
Ideally, if resources permit, "universal precautions" to protect all E.D. personnel from patients' blood and body fluids should be followed
These involve :Eye protection (goggles or face shields)GlovesWaterproof gownsShoe covers
Additional protection using a lead gown is recommended for E.D. personnel if they will be in the room when X-rays are taken
![Page 9: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/9.jpg)
A : Airway (& Cervical spine control)
B : Breathing C : Circulation (hemorrhage
control) D : Disability (mini-neurologic
exam) E : Expose / environment(To some extent D and E are really
part of the secondary survey)
The Primary Survey
![Page 10: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/10.jpg)
How to Do the Primary Survey
Look at the patient from across the room :Is he breathing ?Is he speaking ?What is his skin color ?Is he bleeding ?Is he immobilized properly ?
Obtain a quick history of what happened :Mechanism of injuryTime of injury
![Page 11: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/11.jpg)
How to Do the Primary Survey (cont.)
Assess the airwayDo airway-opening maneuvers if necessary (maintain cervical spine injury precautions)Place oral airway, if unconscious
Assess breathing Listen with stethescope to the chestObtain pulse oximetry if availableBag - valve - mask (BVM) assisted ventilation if neededStart oxygen by high flow face mask on all patients
Early cervical spine injury precautions :Immobilize the neck if any possibility of neck injury"Hard" collarBlocks on either side of head and tape across forehead
![Page 12: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/12.jpg)
Patients Who Might Have a Neck Injury and Need Early Cervical Spine Immobilization
Appropriate mechanism of injuryFallVehicle accidentStruck by object on neck or head
Unconscious Complaining of neck pain Crepitus, contusion, or
deformity of posterior neck Altered mental status (alcohol,
etc.)
![Page 13: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/13.jpg)
How to Do the Primary Survey (cont.) Assess circulation
Check pulse, blood pressure, respiratory rateAlso check temperature if it can be done quicklyCheck for external bleeding and apply direct pressure with gauze dressingsPlace cardiac monitor leads and determine the patient's cardiac rhythm
![Page 14: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/14.jpg)
Emergency Resuscitation Procedures That Should Be Done Immediately With the Primary Survey
If inadequate airway : Airway opening maneuversOral airway if unconscious
If inadequate breathing :Attempt BVM ventilationConsider Heimlich maneuverEndotracheally intubate if BVM inadequate or unsuccessful
![Page 15: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/15.jpg)
Emergency Endotracheal Intubation
Oral intubation with assistant holding head and neck steady usually best
May attempt nasal intubation if :No possible nasal or mid-facial fracturesNo known coagulopathy
Consider "backup" alternative intubation techniques if unable to orotracheally or nasotracheally intubate
Surgical airway (cricothyroidotomy) if endotracheal attempt unsuccessful
![Page 16: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/16.jpg)
Emergency Resuscitation Procedures That Should Be Done Immediately With the Primary Survey (cont.)
If inadequate circulation or suspected major blood loss :Start at least one large bore IV (at least 18 gauge, preferably 16 or 14 gauge)Run lactated ringers (preferred) or normal salineRun very slow if only isolated closed head injuryRun wide open (very fast) if patient hypotensiveRapidly infuse O-negative blood 2 or more units if obvious ongoing blood loss and severely hypotensive
![Page 17: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/17.jpg)
Initial Blood Draw With the IV stick, draw tubes of
blood :Type and cross : most important (red top tube)CBC, Amylase, Glucose, Electrolytes, BUN, platelet count, PT, PTT, Creatinine, CPK, medication levels, pregnancy testDrug (especially alcohol) or toxin levels may also be needed
![Page 18: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/18.jpg)
Emergency Resuscitation Procedures That Should Be Done Immediately With the Primary Survey (cont.)
If major external bleeding :Apply direct pressure with gauze dressingsRarely direct clamping of visible pumping lacerated arteries may be needed (clamps can damage adjacent nerves however)Apply sterile dressings to cover any open fractures or exposed visceraTourniquets are almost never indicated
![Page 19: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/19.jpg)
Emergency Resuscitation Procedures That Should Be Done Immediately With the Primary Survey (cont.)
After assessment of the patient's chest :Suspected tension pneumothorax : immediate needle thoracostomy, then follow with tube thoracostomyFlail chest : stabilization with broad taping or overlying heavy flat dressing
Open "sucking" pneumothorax : seal defect with gauze and dressing ; insert thoracostomy tubeSuspected pericardial tamponade with imminent cardiac arrest :perform pericardiocentsis (very rarely indicated)Consider checking an arterial blood gas (ABG)
![Page 20: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/20.jpg)
Completion of the Primary Survey
Once you have completed assessment of the ABC's and done appropriate resuscitation procedures, the primary survey is completed and you should go on to the secondary survey
![Page 21: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/21.jpg)
Sequential Priorities of the Secondary Survey
Completely undress patient to allow complete exam : clothing may need to be cut off if movement may hurt the patient
Use room warming, heat lamps, and / or heating blanket to help protect the patient against hypothermia
Recheck the vital signs : obtain temperature if not done yet
Complete head to toe exam Consider nasogastric (NG) and/ or urinary bladder
(foley) tube placement (if no contraindications are found on exam)
Decide what X-ray studies are needed : usual minimum to obtain emergently are chest X-ray (CXR), lateral c-spine, and pelvis
Decide if other lab studies are needed
![Page 22: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/22.jpg)
Secondary Survey
First, clarify the history of injury One simple mnemonic is AMPLE
AllergiesMedicationsPast IllnessesLast meal (time)Events (preceding injury)
Clarify mechanism of injury Assess for other conditions
Hypoglycemia, toxin exposure, smoke or carbon monoxide exposure
![Page 23: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/23.jpg)
Secondary Survey : How to Start the Head to Toe Exam Assess mental status : assign Glasgow
Coma Score Palpate scalp (use gloves) Look at tympanic membranes Look at nasal passages Look in mouth Palpate face and mandible Assess pupillary light reaction and
extraocular movements Fundoscopy can be done, but not usually
helpful
![Page 24: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/24.jpg)
Secondary Survey : Neck and Chest
Hold patient's head and neck stable Open the c-collar and observe anterior neck : check tracheal positionPalpate posterior neckReapply collar
Percuss and palpate chest wall and clavicles
Auscultate lungs Auscultate heart Palpate upper back
![Page 25: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/25.jpg)
Secondary Survey : Abdomen, Perineum, and Back
Auscultate and palpate and percuss abdomen
Palpate backCostovertebral angles, spinous processes, paraspinous muscles
Palpate and rock pelvis Logroll patient to look at back ( maintain
spine and limb stability with the logroll ) Palpate genitalia
Vaginal exam Rectal exam
Check for high-riding prostateCheck stool guiac
![Page 26: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/26.jpg)
Secondary Survey : Exam of Extremities Palpate along all four limbs Assess active joint range of
motion Palpate pulse and capillary refill Assess tendon function
![Page 27: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/27.jpg)
Secondary Survey : Neurologic Exam
Assign Glasgow Coma Scale score (GCS)
Mental status / orientation ( to person, place, time, events)
Cranial nerves II thru XII Motor Sensory (all four
limbs) Reflexes Coordination
![Page 28: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/28.jpg)
Secondary Survey : Additional Considerations
Splint and bandage injuries as these are discovered
Cleanse dirty wounds to allow better assessment of their depth and extent
Leave deeply imbedded objects in place for removal in the operating room ( premature removal could result in exsanguination if the object is tamponading a major vessel )
![Page 29: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/29.jpg)
Secondary Survey : Final Considerations Consider 12 lead EKG ( if hypotensive, major
chest trauma or chest pain ) Usually minimum X-rays needed are (for major
truncal trauma) : lateral C-spine, CXR, AP pelvis (order these while doing secondary survey)
X-ray all sites of potential fractures (order these all at one time for greatest efficiency )
Decide if special studies needed :Peritoneal lavage, computed tomography, angiography, ultrasound
Place foley and / or NG tube if no contraindications
![Page 30: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/30.jpg)
Contraindications to NG or Foley Insertion NG tube
Nasal fractures, midfacial fractures, severe coagulopathy Insert via mouth ( "orogastric tube" ) if any of these are present
FoleySuspected anterior urethral injury : blood at meatus, "high-riding" or nonpalpable prostate, "butterfly" perineal hematoma
![Page 31: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/31.jpg)
![Page 32: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/32.jpg)
After Completion of the Secondary Survey
Decide if the patient will need to be transferred to another medical facility and start arranging this while the patient is being X-rayed
Talk to the patient's family and advise them about the patient's injuries identified so far
If the patient still is unstable or requires further resuscitation, do not leave the bedside
Consider pain medications once the exam is complete
Continue to reevaluate the patient and repeat vital signs frequently as long as he is in your care
Monitor urine output and any other drains or fluid output
![Page 33: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/33.jpg)
Initial Assessment Summary
First : Primary Survey / ResuscitationABCDE
Next : Secondary SurveyX-rays, labwork, NG, Foley
Next : ReassessmentFinal diagnosesDecide on disposition; Options are :Discharge home, admit to ward, admit to ICU, admit to operating room, transfer to another facility
![Page 34: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/34.jpg)
Triage Decisions When There Are Multiple Simultaneous Trauma Victims
Capabilities of the medical facility are exceeded by the situation :Treat the patients first that have the greatest chance of survivalTreat the patients first that require the least time, personnel, or equipment
Capabilities of the facility are not exceeded by the situation :Treat first the patients with life threatening or multiple injuries
![Page 35: Initial Assessment of the Trauma Patient. Initial Assessment of the Trauma Patient Objectives Identify and treat immediately life- threatening injuries.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649f1d5503460f94c33906/html5/thumbnails/35.jpg)
Considerations for Forensic Evidence
If injury is due to suspected criminal activity or intent :Notify law enforcement personnelSave all the patient's clothing and other belongingsCut around, not through, bullet or stab holes in clothingWidely separate the suspected perpetrator and victim(s)
