Gluteal CS is difficult to diagnose, as peripheral pulses will be present despite the increase in the compartment pressure and, besides, the other injuries that are present tend to divert the attention of the treating physician. [ncbi.nlm.nih.gov]
Entire Body System
- Collapse
When the site does not shore and secure these trenches properly, the sides of the trench can collapse and crush anyone caught inside of them. Typically, trench collapses are fatal. [koonz.com]
As the quake struck, the structure collapsed on top of Peña, trapping him in the sweeper under concrete support beams. [fireengineering.com]
Persons freed from the site of collapse usually have a normal pulse and blood pressure at first. As soon as the injured part of the body begins to swell with blood from the ruptured vessels, shock occurs. [britannica.com]
The reason for this is that once the interstitial fluid pressure is reduced below the capillary perfusion pressure, the collapsed microcirculation can again open-up and allow perfusion to resume. [uhms.org]

He was fully conscious but dehydrated and complained of severe pain in both lower limbs and buttocks. He was tachycardic but blood pressure was stable. [ncbi.nlm.nih.gov]
Respiratoric
- Dyspnea
Histamine release causes vasodilation and bronchoconstriction, resulting in dyspnea and possible respiratory distress. Nitric oxide can worsen hypovolemic shock by causing vasodilation. [jems.com]
Cardiovascular
- Hypotension
The release of lactic acid can also cause metabolic acidosis, which can result in hypotension if the levels get too high. [emsworld.com]
Ischaemic renal dysfunction secondary to hypotension and diminished renal perfusion results in acute tubular necrosis and uraemia." [ 1 ] It is also known as Bywaters' syndrome. [patient.info]
The influx of water results in intravascular volume depletion, leading to hypotension. 2 With the continued entrapment of the patient’s limb, hypoperfusion worsens, contributing to tissue hypoxia. [jems.com]
Yet following inadvertent calf compression and intra-operative hypotension, intra-compartmental calf pressures in excess of 35mmHg have been controlled by prompt HBO treatment without the need for fasciotomy (Van Poucke S). [ddrc.org]
Clinical features Some or all of the following clinical signs and symptoms may be present: Cardiovascular instability Hypotension and hypovolemic shock. [cancertherapyadvisor.com]
Musculoskeletal
- Myalgia
Rhabdomyolysis classically presents with myalgia, generalized weakness, and darkened urine (myoglobinuria). Complications include acute kidney injury and crush syndrome, the systemic manifestation of traumatic rhabdomyolysis. [amboss.com]
Myalgia, muscle paralysis and sensory deficit are common. Fever, cardiac arrhythmia, pneumonia, ‘tea or cola’ coloured urine, oliguria and renal failure are the sequence of events. [ncbi.nlm.nih.gov]
Neurologic
- Paresthesia
Early examination findings will show pain disproportionate to the injury and paresthesia. Pain is worse with passive stretching of the muscles in the compartment (e.g., dorsiflexion of the foot for a compartment syndrome of the calf). [emsworld.com]
Metabolic acidosis with lactic acidosis Disseminated intravascular coagulopathy Hypothermia Myoglobinuria Skin injury and swelling Paralysis and paresthesia Pulses may or may not be present. [cancertherapyadvisor.com]
They may experience paresthesia — or numbness — that can actually mask their true level of pain. 3. [ems1.com]
The signs and symptoms of compartment syndrome in an extremity include pain out of proportion to the injury or with passive motion, pallor, paresthesia, pulselessness, and paralysis of the affected extremity. [nursingcenter.com]
Pain out of proportion to the injury or precipitated by passive movement of the extremity or fingers; a pale and swollen affected extremity; paresthesia of the extremity, with the first sensation to be lost being the sense of vibration;[ 8 ] and pulselessness [ncbi.nlm.nih.gov]
- Tingling
Crush injuries can cause ongoing symptoms such as: Chronic pain Weakness in the affected limb Tingling Numbness Stiffness Permanent paralysis In some cases, damage is so severe that doctors may elect to amputate the affected limb. [hasnerlaw.com]
The muscle may feel tight, or there may be burning or tingling in the skin. Acute compartment syndrome is a medical emergency that requires immediate surgery. Rhabdomyolysis. [attorneystevelee.com]

Treatment should be based on clinical findings such as anxiety, numbness and tingling, nausea/vomiting, ECG abnormalities suggestive of elevated potassium levels, or actual laboratory values. [nursingcenter.com]
- Agitation
Nausea, vomiting, confusion and agitation may occur as consequences of disturbed body chemistry; urea, creatinine, uric acid, potassium, phosphate and creatine kinase are elevated. There may also be hypocalcaemia. [patient.info]
Nausea, vomiting, agitation and delirium are seen in the delayed rescue patients. Investigations Serum creatinine kinase (CKMM) levels greater than 1000 IU/l with associated clinical features is generally taken as an indicator of crush syndrome. [ncbi.nlm.nih.gov]
- Irritability
A very recent product in the market is the absorbable JuggerKnot® soft Anchor 1.0 mm mini where there is no metal implant hence no chance of irritation to adjacent tendons ( Figure 17 ). Figure 17. [intechopen.com]
Urogenital
- Kidney Failure
STORY HIGHLIGHTS Haiti earthquake survivors are experiencing kidney failure, a major health concern When a muscle ruptures it releases particles that get trapped in kidneys Rhabdomyolysis can lead to kidney failure and death if a patient is not hydrated [edition.cnn.com]
Sometimes limbs must be amputated, and muscles can rupture, releasing cellular content and causing kidney failure, embolisms or cardiac arrest. [attorneync.com]
If the blood flow is restricted or impaired for more than 15 minutes, toxins can be released into the rest of the body and cause kidney failure. This process called 'Crush Syndrome' and the patient is at a high risk of death. [firstresponse.org.uk]
Rhabdomyolysis – When muscle tissue dies, it may release its contents into the bloodstream which can cause kidney failure. Treatment For minor crush injuries, you may be able to heal without medical attention. [oastaug.com]
- Oliguria
It was found that removal of the extremity from the press after five hours was followed by swelling of the thigh, an increase in the concentration of the blood, a decline in blood pressure, oliguria, abnormal urinary findings, elevated blood creatine [jamanetwork.com]
Malignant hyperthermia References: [2] [3] Pathophysiology Clinical features Rhabdomyolysis Classic triad Myalgia Generalized weakness Darkened urine (red to brown) Nonspecific symptoms : fever ;, nausea, vomiting Complications Acute kidney injury : oliguria [amboss.com]
The appearance, duration and gravity of oliguria and kidney damage are not related to the severity of muscle damage [ 6 ]. The muscles are grossly swollen, hard, cold, insensitive and necrotic. [ncbi.nlm.nih.gov]
Dialysis and Hemofiltration Oliguria or anuria responsive to treatment, fluid therapy, volume overload, and a rising serum potassium (47 mEq/L) are indicators of the need for dialysis. [cancertherapyadvisor.com]
There may be oliguria with profound hypovolaemic shock. Nausea, vomiting, confusion and agitation may occur as consequences of disturbed body chemistry; urea, creatinine, uric acid, potassium, phosphate and creatine kinase are elevated. [patient.info]
- Renal Injury
Renal injury occurs mainly due to two mechanisms: first, myoglobin causes obstruction of the renal tubules and, second, the nephrotoxicity of myoglobin leads to renal vasoconstriction. Acute renal failure results if this is not treated. [ncbi.nlm.nih.gov]
Treatment
[…] hyperbaric treatment (21% O2 at 1.1 ATA, identical treatment schedule). [ddrc.org]
Treatment- Firstly, any wounds that are present will need to be cleaned and bandaged to prevent infection. Treatments for a foot crush injury may also include medication, casting, kinesiology taping, ice and heat, physical therapy, or surgery. [lakeridgefootankle.com]
Conclusion Now that we have reviewed the syndrome and its treatment, let’s get back to our patient who's trapped in the structural collapse. [emsworld.com]
Standard treatment modalities such as calcium, insulin, dextrose, and an exchange resin may temporize the situation; however, dialysis may be needed for definitive treatment. Table 2 provides a review on the treatment of hyperkalemia. Table 1. [nursingcenter.com]
Prognosis
Prognosis Crush injuries have a high death rate. They are associated with multi-organ damage at times that may not be reversible. Function of the injured muscle should return if the tissue did not die. [pagelaw.com]
If levels continue to elevate, consider ongoing muscle injury or compartment syndrome. [ 11 ] Prognosis Adequate fluid support improves prognosis. [ 12 ] The mortality rate for crush syndrome following the earthquake in northern Turkey in 1999 was 15.2% [patient.info]
