The 68-year-old man with no prior medical history presented to our emergency department 48 hours after sustaining a snakebite to the volar aspect of his left wrist. Immediately following the bite, he experienced severe localized pain and rapidly spreading edema of the hand. He initially sought traditional local remedies.
The Fatal Presentation and Rapid Deterioration
By the time he arrived at the emergency department, the patient presented with massive progressive swelling of the left upper limb, profound metabolic acidosis, severe consumptive coagulopathy, and refractory shock.
Medical teams faced an immediate, high-stakes collision between local limb preservation and systemic resuscitation. Surgical decompression was strongly considered due to high clinical suspicion of acute compartment syndrome; however, emergency fasciotomy could not be safely performed owing to severe hemodynamic instability and uncorrected coagulopathy. Despite aggressive resuscitation, antivenom administration, and hemostatic support, the patient rapidly deteriorated and developed refractory cardiac arrest, culminating in death 90 minutes after admission in the setting of overwhelming systemic envenomation.
Recognizing the Warnings of Muscle Compartment Pressure
Acute compartment syndrome is a painful condition caused by a pressure build up in a group of muscles. Compartment syndrome most commonly happens in the legs or forearms. In these areas, there are groups of muscles surrounded by bone and fascia (a tough sheath of tissue with little stretch). There are 2 types of compartment syndrome: Acute compartment syndrome — usually happens suddenly after an injury. It’s extremely painful and needs urgent treatment to prevent permanent damage. Chronic exertional compartment syndrome — can happen with intense, repetitive exercise. It usually gets better with rest.
In acute compartment syndrome, the high pressure can be caused by bleeding or swelling from an injury. Because there is little room for expansion with swelling, the pressure in the muscle compartment rises. When the pressure reaches a dangerous level, it can reduce or cut off blood flow to the area. This means that oxygen is not able to reach the tissues in the affected area. The muscle tissue may then start to die and break down.
Diagnosing compartment syndrome is often much more difficult than treating it. Sometimes swelling improves temporarily with ice and elevation, and sometimes symptoms show up after the window to save healthy tissue has already narrowed.
Historically, doctors have been taught to look for the “six Ps,” the symptoms of compartment syndrome: Pain, Paresthesia (numbness or tingling), Pallor (pale skin), Paralysis, Pulselessness, Poikilothermia (the limb is cold to touch). Pain is usually the earliest clue, especially pain that seems worse than expected for the injury or becomes severe when the muscles are stretched. However, many patients with major fractures or crush injuries are already in significant pain. If they have a head injury, are sedated, or are on a ventilator, they may not be able to describe their symptoms.
Acute compartment syndrome symptoms include: intense pain — more painful than you might expect from your injury, pain that is not controlled with pain-relief medicines, increased pain and a feeling of tightness when you stretch the affected muscles, numbness, paralysis (lack of movement) of the affected area, and pale, cold skin. The affected area may feel firm to touch.
Causes and Diagnostic Challenges in Resource-Limited Settings
You can develop acute compartment syndrome after a serious injury such as a bone fracture, crush injury (for example, from a car accident), penetrating injury, or surgery. Other causes can include very tight bandages or casts over an injury, a snake bite or injury from other venomous creatures, such as fish and stingrays, severe burns, or severe bruising. Your risk of acute compartment syndrome is higher if you have an increased risk of bleeding. This may be due to a condition or medicine you are taking.
Distinguishing suspected ACS from venom-induced pseudo-compartment syndrome remains a major clinical challenge, as unnecessary fasciotomy in a coagulopathic patient carries substantial risks, whereas delayed decompression may result in irreversible ischemic injury. This case highlights both the diagnostic uncertainty surrounding ACS without access to intracompartmental pressure monitoring and the critical therapeutic dilemma of managing severe local complications alongside life-threatening systemic toxicity.
This is why close, expert monitoring of the patient’s pressure status over time is crucial for the best chance of saving the limb. UT Southwestern is one of the first teams in Texas to start using a new purpose-built continuous compartment pressure monitor tool instead of relying on a one-time reading. We place an indwelling pressure monitor within the patient’s affected compartment using a catheter. Data from the tool tracks pressure trends over the next 24 hours to help us make a faster, more precise diagnosis.
Acute compartment syndrome is measured in minutes, not days or weeks. Once the diagnosis is made, the patient needs emergency surgery as soon as possible. A missed diagnosis can leave someone with a painful, weak, and potentially functionless limb. In cases of extreme tissue damage, patients may need amputation.
If you suspect that you or a loved one may have compartment syndrome, call triple zero (000) and ask for an ambulance or go immediately to an emergency department.
