Case Title: Multi-System Trauma

CASE SUMMARY

CORE CONTENT AREA

Trauma, Orthopedics

SYNOPSIS OF CASEThis is a trauma patient who presents after a high velocity motorcycle crash. He is critically ill upon presentation and needs several immediate procedures for stabilization. Including intubation, IVF resuscitation and blood products, as well as reduction of a knee dislocation with neurovascular compromise. There are no diagnostic challenges in the case, if the candidate follows basic ATLS guidelines.

SYNOPSIS OF HISTORYThe patient was part of a multiple car pile up on a nearby highway. Other victims are at various local Trauma Centers. He was wearing a helmet, and broadsided a vehicle as it made a rapid lane change to avoid another vehicle. The patient was ejected from his motorcycle, landing on the shoulder of the road in some brush. He was minimally responsive on scene, but EMS was unable to obtain a definitive airway. One victim was pronounced dead at the scene. No family or PMH are available during the initial stages of the case.

SYNOPSIS OF PHYSICALPhysical exam findings are not subtle in this case. Dental trauma and blood in airway, as well as decreased level of consciousness require intubation. Hemotympanum is noted on the left. He is very tachycardic, pulses are thready. Abdomen is soft, but a large ecchymosis over the right flank is evident. Right knee is grossly deformed and is obviously dislocated. The right DP and PT pulses are not palpable. The foot is cool with delayed cap refill.

CRITICAL ACTIONS1. Immediate intubation while maintaining C-spine immobilization 2. Perform a basic neurologic exam (pupils, corneal reflexes, withdrawal to pain) prior to giving paralytics3. Aggressive IVF and blood product administration for hypotension/shock4. Perform a FAST exam and recognize intraperitoneal hemorrhage5. Recognize and immediately reduce R knee dislocation, verify pulses are present after Reduction6. Obtain CXR, Pelvis XR, & C-spine XR in hemodynamically unstable multi-trauma patient7. Call the Trauma surgeon for immediate OR resuscitation. NO CT IMAGING!8. Explain patient’s condition to the family in the waiting room

CRITICAL ACTIONSSCENARIO BRANCH POINTS/ PLAY OF CASE GUIDELINES

1. Critical Action: Immediate intubation while maintaining C-spine immobilization

This critical action is met by the candidate's quick recognition that the patient is obtunded and has blood in his airway. The examiner may use their discretion and make the intubation difficult, easy, etc. based on how the candidate is performing thus far.

Cueing Guideline: A medical student may ask “Should I hold his neck while you intubate?”

2. Critical Action: Perform a basic neurologic exam prior to paralytics

This critical action is met by the candidate's performing a rudimentary neurologic exam prior to paralyzing him for RSI. This is accomplished by assessing the pupils and assessing his response to painful stimuli, and can also include checking for corneal reflexes, gag, etc.

Cueing Guideline: A nurse may ask: “What’s his GCS?” or “What are his pupils like?” just prior to intubation

3. Critical Action: Aggressive IVF and blood product administration for hypotension/shock

This critical action is met by the candidate's rapid recognition of hypotension due to hypovolemic shock. Therapy should begin with isotonic IVF, then when minimal improvement is noted, should progress to blood products.

Cueing Guideline: The nurse may ask: “Doctor, he’s not really getting much better with these fluids, do you want to give anything else?” IF the participant still does not ask for blood, then the blood bank tech who is in the ED may ask “Doctor, will you be needing any blood?”

4. Critical Action: Perform a FAST exam and recognize peritoneal hemorrhage

This critical action is met by the candidate's performing a rapid FAST exam with the ED U/S machine. In addition, the candidate must correctly interpret the positive U/S results.

Cueing Guideline: The nurse may state: “I wonder why he’s not improving. Do you think he’s still losing blood somewhere?” IF the participant still does not ask for an U/S, a medical student may ask: “How can we figure out where he’s bleeding?” IF the participant still does not ask for an U/S, the nurse may ask: “Will you be needing the ultrasound during this case?”

Johnny Blade; 27 4/5/1983

For Examiner Only CRITICAL ACTIONS (continued)

5. Critical Action: Recognize and immediately reduce R knee dislocation, verify pulses are present after reduction

This critical action is met by the candidate's recognition that the knee is grossly deformed (only if candidate does an extremity exam) and that the right foot perfusion is compromised. They should immediately give some analgesia and reduce the knee, followed by reassessing the pulses and perfusion in the right foot. The leg should then be immobilized.

Cueing Guideline: The nurse may ask: “What do you think about his leg, is it broken?”

6. Critical Action: Obtain CXR, Pelvis XR & C-spine XR in hemodynamically unstable multi-trauma patient

This critical action is met by ordering a CXR, Pelvis XR, & lateral C-spine XR.

Cueing Guideline: The nurse may state: “Radiology would like to know if you want any plain films on this patient.”

7. Critical Action: Call the Trauma surgeon for immediate OR resuscitation

This critical action is met by the candidate's recognition and understanding of the U/S results. With this information, he/she must now contact the Trauma Surgeon and inform them of the need for an OR resuscitation. The candidate MUST NOT allow the patient to go to the CT scanner.

Cueing Guideline: If the candidate is ordering CT imaging, the CT tech on the phone will ask: “Is your patient stable enough to come to the CT scanner?”

8. Critical Action: Explain patient’s condition to family in the waiting room

This critical action is met by the candidate's asking if family has yet arrived. When they are present, the candidate should take the time to explain the patient’s condition and answer their questions. The candidate should be empathetic and respectful in his/her demeanor.

Cueing Guideline: If the candidate does not ask about family, the Social Worker will say:“Doctor, this patient’s family is now in the waiting room. They are very distraught and would like to speak with you.”

PLAY OF CASE GUIDELINES

This is a critically ill motorcycle crash victim. He was a helmeted rider that struck another car at freeway speeds. He was ejected from his motorcycle and found 20 feet from his bike in some scrub brush along the freeway shoulder. Another driver involved in the crash was pronounced dead at the scene. EMS reports getting 2 large IVs but were unable to intubate. He was mildly hypotensive en route (SBP in the low 90-100 range). He has been unresponsive throughout transport. No known PMH. Police are calling to notify family at this time.

The candidate needs to perform multiple life & limb saving interventions immediately in the ED, including intubation, administering IVF and blood products, and reducing the knee dislocation (and verify the improved perfusion of the foot after reduction). After initial stabilization, the candidate should perform a FAST exam and recognize hemoperitoneum. Xrays of the C-spine, chest, pelvis, and right knee should all be obtained.

The candidate should frequently reassess indices of perfusion including urine output, as well as frequent BP monitoring (noninvasive or via arterial line). The candidate SHOULD NOT allow the Trauma surgeon, nurses, etc to convince him/her to send the patient to CT. If so, the patient will code in the scanner and not respond to any resuscitative efforts.

SCORING GUIDELINES

1. Score up if they ask EMS personnel to stay around, and obtain a detailed history from the EMS providers after the primary survey is complete

2. Score up if they intubate expeditiously; score down if they continue on to the secondary survey before intubating

3. Score up if they vocalize that they will maintain C-spine immobilization during intubation; score down if they do not

4. Score up if they use head injury specific medications for / with RSI (lidocaine, fentanyl, etc.)5. Score up if they recognize clinical findings of ICH (obtundation, facial trauma and

hemotympanum)6. Score up if they reduce the knee dislocation and verbalize that angiography will be needed

once he is stable

Johnny Blade; 27 4/5/1983

despite crystalloid infusion, PRBCs should be infused (5-10 ml/kg). Type-specific blood should be used when the clinical scenario permits, but uncrossmatched blood should be immediately used for patients with hypotension and uncontrolled hemorrhage. O-negative blood is used in women of childbearing age and O-positive blood in all others.

3.) FAST Exam: “FAST” is an acronym for Focused Assessment with Sonography in Trauma and has become synonymous with beside ultrasound in trauma. The FAST exam, per ATLS protocol, is performed immediately after the primary survey of the ATLS protocol.  Ultrasound is the ideal initial imaging modality because it can be performed simultaneously with other resuscitative cares, providing vital information without the time delay caused by radiographs or computed tomography (CT).  The concept behind the FAST exam is that many life-threatening injuries cause bleeding.  Although ultrasound is not 100% sensitive for identifying all bleeding, it is nearly perfect for recognizing intraperitoneal bleeding in hypotensive patients who need an emergent laparotomy.
