Coping With the Fear of Compartment Syndrome Without Compromising Analgesia: A Narrative Review

Abstract

Pain management in trauma or surgery with a high risk of developing compartment syndrome (CS) is always challenging due to fears of masking symptoms that could delay diagnosis and treatment. Regional anesthesia/analgesia (RA) can facilitate enhanced postoperative recovery and improve patient satisfaction by providing excellent postoperative analgesia. However, its consideration in surgeries with a high risk of developing CS remains controversial and contentious. Studies suggest focusing more on early diagnosis through regular vigilant monitoring with a high index of suspicion rather than discontinuing the analgesic method alone. The most consistent features in all reported cases of CS were altered sensation in the affected limb, disproportionate pain in the presence of a functional nerve block, and an escalating need for analgesics. Several extrinsic or intrinsic factors are responsible for the progressive increase in compartment pressure that can lead to vascular compromise and subsequent ischemic changes in muscles, tissues, and nerves. Measurement of intracompartmental pressure (ICP) has always been considered the gold standard for diagnosing CS. An ICP of 30 mm Hg is considered the cut-off point for fasciotomy that helps restore muscle perfusion and avoid irreversible tissue damage. The chronology of symptoms can sometimes provide clues to the severity of CS, the pathophysiology involved, and the management required. Therefore, it is necessary to look for warning signs, further investigate the causes, and make quick decisions to diagnose and treat CS and its complications on time. Any delay in the diagnosis and treatment of CS can result in high morbidity and poor outcomes. A well-integrated interprofessional team of health professionals can deliver the required complexity of care through a holistic and multidisciplinary approach. This review article highlights the symptoms, risk factors, and pathophysiology involved in CS. It can guide readers in choosing various options to diagnose, prevent, and treat CS. It also discusses the role of RA in patients or surgeries prone to developing CS.
