Acute Extremity Compartment Syndrome and (Regional): Anesthesia: The Monster Under the Bed

Area of Science:

• Orthopedic Surgery
• Anesthesiology
• Trauma Care

Background:

• Acute compartment syndrome (ACS) is a critical orthopedic emergency requiring prompt intervention to prevent irreversible damage.
• The use of regional anesthesia (RA) for pain management in patients susceptible to ACS is a subject of ongoing debate.
• Concerns exist regarding whether RA might obscure or delay ACS diagnosis.

Purpose of the Study:

• To critically review existing literature on the impact of regional anesthesia on the diagnosis of acute compartment syndrome.
• To determine if regional anesthesia techniques delay or potentially facilitate the timely diagnosis of ACS.
• To clarify the controversial role of RA in managing patients at risk for ACS.

Main Methods:

• Critical review of published literature.
• Analysis of studies investigating the use of regional anesthesia in patients with or at risk for acute compartment syndrome.
• Evaluation of evidence regarding the effect of RA on diagnostic timelines for ACS.

Main Results:

• Peripheral regional anesthesia administered alone does not appear to delay the diagnosis or surgical treatment of ACS.
• A small number of reported cases (4) suggest that epidural analgesia may be associated with a delay in ACS diagnosis.
• The overall evidence indicates that RA is not a significant impediment to ACS diagnosis.

Conclusions:

• Peripheral regional anesthesia is a viable option for analgesia in patients at risk for ACS without compromising diagnosis.
• Epidural analgesia warrants cautious consideration due to potential associations with delayed ACS diagnosis in specific instances.
• Further research may be needed to fully elucidate the nuanced relationship between different RA techniques and ACS diagnosis.
