3 Compartment Syndrome Chris DeFlitch, MD, FACEP Director & Vice-Chair
Department of Emergency Medicine Penn State Hershey Medical Center

4 Case Presentation 23yo deaf male with Left lower extremity injury after motocross event Questions?

5 History that’s Important
Mechanism of Injury Associated Complaints Associated Injury P Q R S T

6 Physical Findings ? ABC’s Associated Injury Local Examination
Vital Signs Associated Injury Local Examination Joint Above & Below Neurovascular Status

7 What’s the Differential Dx?
Life threatening Most Common Bizzare Stuff Things to Impress your Attending

8 What YOUR Assessment & Plan ?
Anti-inflammatory medications ? Narcotics ? Imaging ? Consultation ? Ask the Attending ?

9 Your Interpretation Want another view ? Source undetermined

10 Diagnosis ? YEP…ITS NORMAL Source undetermined

11 What’s the ED Disposition ?
Admission Observation Discharge Consultation for Specific Procedure 3. DISCHARGE

12 Guess What……. The patient came back with…..
Increasing PAIN, especially with Passive range of motion Paresthesia Pallor Pulselessness Paralysis And had COMPARTMENT SYNDROME

13 Objectives Define Compartment Syndrome Understand the Pathophysiology
Consider Anatomic Factors Identify Signs & Symptoms Define Diagnostic & Treatment Options

14 Compartment Syndrome TRUE EMERGENCY
Increase Pressure in Closed space (compartments) Most Common with Leg Injury/Fracture Can occur with thigh, forearm, arm, hand, or foot injury

15 Mechanism Associated Crush Injury Fractures (closed) Burns
Prolonged Procedures/Pressure Spontaneous Hemorrhage External Pressure (cast, MAST) Overuse Syndromes

16 Pathophysiology Increased Pressure in a CLOSED compartment
Increased Compartment Contents Decreased Compartment Space/volume Increased External Pressure

17 Cellular Physiology Compartment Pressure > Diastolic
Venous vascular congestion Tissue Ischemia Release of Histamine increasing membrane permeability Increasing Compartment Pressure Arterial Vasospasm plays a minimal Role

18 Anatomic Considerations
CAN affect ANY CLOSED COMPARTMENT Leg Anterior – MOST FREQUENT Lateral Deep Posterior Superficial Posterior

19 Other Extremities Thigh Hand & Foot Forearm Arm Quadriceps
Interosseous Forearm Dorsal Volar Arm Biceps Deltoid

20 CLASSIC “5 P’s” Pain Paralysis Paresthesia Pallor Pulselessness
Said together, but if they’re all there …the 6th P…….PATIENT is in trouble

21 Clinical Presentation
Pain Out of Proportion to exam Deep, burning, Unrelenting Frequent Revisit for MORE PAIN MEDS THEY AIN’T DRUG SEEKERS !!!!

22 Physical Exam Pain with PASSIVE stretching Pain with Active Flexing
Paralysis (secondary to pain) Tense or “full” compartment Be Careful….some you can’t palpate

23 The other 3 P’s Paresthesia – earlier sign PALLOR Pulselessness
LATE, OMINOUS SIGNS

24 Diagnosis High Index of Suspicion GOOD H&P
Insure neurovascularity Intact Consider extremity XR Early Orthopedic Consultation Compartment Pressure Measurement >30 mmHg

25 Pressure Measurement Stryker Machine (needle with transducer)
Baseline machine to atmosphere pressure Should Read ZERO Prep Area 18 G Needle into Compartment Sometime hard with SMALL compartment Inject small amount of Saline Measure Plateau Pressure At Least 2 times

26 Tissue Pressure Gradient
0 mmHg NORMAL 10-30 mmHg Variable 30 mmHg Microcirculation Impaired Within 30 mmHg of diastolic BP Tissue Ischemia

27 Complications Tissue Necrosis & Loss Rhabdomyolysis---Renal Failure
Nerve damage Contractures Amputation Cosmetic Deficit Rhabdomyolysis---Renal Failure Hyperkalemia Myoglobinuria

28 Fasciotomy Definitive Treatment Indication For Fasciotomy
OPEN the Closed Compartment Indication For Fasciotomy Pressures >30 Pressures within 30mmHg of Mean Arterial Pressure

29 Back to the Patient Had Clinical findings of Compartment syndrome
LATE Findings Flown to Tertiary Care Medical Center Fasciotomy Prolonged Course

30 The OUTCOME He still has his Leg
BUT with a Significant Cosmetic & Functional Defect

31 QUESTIONS ? THANK YOU !!!!!
