Summary

AI-generated

This guideline provides evidence-based recommendations for the diagnosis and treatment of acute compartment syndrome in adult patients with extremity trauma, addressing diagnostic criteria, pressure monitoring methods, fasciotomy techniques, and subsequent wound and fracture management.

Key Takeaways

  • 1
    Intracompartmental pressure monitoring assists in diagnosing acute compartment syndrome.
  • 2
    A threshold of diastolic blood pressure minus intracompartmental pressure > 30 mmHg assists in ruling out acute compartment syndrome.
  • 3
    In obtunded patients, repeated or continuous intracompartmental pressure measurements are recommended until ACS is diagnosed or ruled out.
  • 4
    Fasciotomy technique is less important than achieving complete decompression of the compartments.
  • 5
    Fasciotomy is not indicated in adult patients with evidence of irreversible intracompartmental damage.
  • 6
    Negative pressure wound therapy is supported for managing fasciotomy wounds to reduce time to closure and skin grafting.
  • 7
    Neuraxial anesthesia may complicate clinical diagnosis of ACS; if used, frequent physical exams and/or pressure monitoring should be performed.

What's New in This Version

The 2025 update is a Rapid Update of the 2018 guideline. The strength of recommendation for 'Associated Fracture' was upgraded from Consensus to Limited based on new evidence supporting operative fixation (external or internal) for initial stabilization of long bone fractures. Additional supporting evidence was added to various sections without changing other recommendations or the original scope.

Key Recommendations

Biomarkers

  • Biomarkers_A

    Limited evidence supports that myoglobinuria and serum troponin level may assist in diagnosing acute compartment syndrome in patients with traumatic lower extremity injury.

    LimitedEvidence: Low to ModerateDiagnosis
  • Biomarkers_B

    Moderate evidence supports that, in patients with acute vascular ischemia, femoral vein lactate concentration sampled during surgical embolectomy may assist in the diagnosis of acute compartment syndrome.

    ModerateEvidence: Moderate to HighDiagnosis
  • Biomarkers_C

    Limited evidence supports that myoglobinuria does not assist in diagnosing acute compartment syndrome in patients with electrical injury.

    LimitedEvidence: Low to ModerateDiagnosis

SERUM BIOMARKERS IN LATE/MISSED ACS

  • Biomarkers_Late_Missed

    In the absence of reliable evidence, it is the opinion of the work group that serum biomarkers do not provide useful information to guide decision making when considering fasciotomy for a presumed late-presentation or missed acute compartment syndrome.

    ConsensusEvidence: No EvidenceDiagnosis/Management

PRESSURE METHODS

  • Pressure_Methods_A

    Moderate evidence supports that intracompartmental pressure monitoring assists in diagnosing acute compartment syndrome.

    ModerateEvidence: Moderate to HighDiagnosis
  • Pressure_Methods_B

    Moderate evidence supports the use of repeated/continuous intracompartmental pressure monitoring and a threshold of diastolic blood pressure minus intracompartmental pressure >30 mmHg to assist in ruling out acute compartment syndrome.

    ModerateEvidence: Moderate to HighDiagnosis

PRESSURE MONITORING IN LATE/MISSED ACS

  • Pressure_Late_Missed

    In the absence of reliable evidence, it is the opinion of the work group that compartment pressure monitoring does not provide useful information to guide decision making when considering fasciotomy for an adult patient with evidence of irreversible intracompartmental (neuromuscular/vascular) damage.

    ConsensusEvidence: No EvidenceDiagnosis/Management

PHYSICAL EXAM (AWAKE)

  • Physical_Exam_Awake

    Limited evidence supports using serial clinical exam findings to assist in ruling in acute compartment syndrome.

    LimitedEvidence: Low to ModerateDiagnosis

PHYSICAL EXAM (OBTUNDED)

  • Physical_Exam_Obtunded

    In the absence of reliable evidence, it is the opinion of the work group that without a dependable clinical examination (e.g. in the obtunded patient), repeated or continuous intracompartmental pressure measurements are recommended until acute compartment syndrome is diagnosed or ruled out.

    ConsensusEvidence: No EvidenceDiagnosis

ALTERNATIVE METHODS OF DIAGNOSIS

  • Alternative_Methods

    In the absence of reliable evidence, it is the opinion of the work group that there are no reported diagnostic modalities, other than direct pressure monitoring or clinical exam findings, that provide useful information to guide decision making when considering fasciotomy for acute compartment syndrome.

    ConsensusEvidence: No EvidenceDiagnosis

FASCIOTOMY METHODS

  • Fasciotomy_Methods

    In the absence of reliable evidence, it is the opinion of the work group that fasciotomy technique (e.g. one vs two incision, placement of incisions) is less important than achieving complete decompression of the compartments of the affected extremity.

    ConsensusEvidence: No EvidenceTreatment

FASCIOTOMY FOR LATE/MISSED ACS

  • Fasciotomy_Late_Missed

    In the absence of reliable evidence, it is the opinion of the work group that performing fasciotomy is not indicated in an adult patient with evidence of irreversible intracompartmental (neuromuscular/vascular) damage. Fracture stabilization, if warranted in these patients, should utilize a technique (external fixation/casting) that does not violate the compartment.

    ConsensusEvidence: No EvidenceTreatment

ASSOCIATED FRACTURE

  • Associated_Fracture

    Limited evidence supports that operative fixation (external or internal) be performed for initial stabilization of long bone fractures with concomitant acute compartment syndrome requiring fasciotomy.

    LimitedEvidence: Low to ModerateTreatment

WOUND MANAGEMENT

  • Wound_Management

    Limited evidence supports use of negative pressure wound therapy for management of fasciotomy wounds with regard to reducing time to wound closure and reducing need for skin grafting.

    LimitedEvidence: Low to ModerateTreatment

PAIN MANAGEMENT EFFECTS ON DIAGNOSIS

  • Pain_Management

    In the absence of reliable evidence, it is the opinion of the work group that neuraxial anesthesia may complicate the clinical diagnosis of acute compartment syndrome. If neuraxial anesthesia is administered, frequent physical examination and/or pressure monitoring should be performed.

    ConsensusEvidence: No EvidenceManagement/Diagnosis
