Reperfusion and pressure 2nd effect as it pertains to crush syndrome: (week 9)

A second effect from pressure and reperfusion is the release of debris from the damaged cells into the circulation. (from nursing centre) This debris includes potassium, phosphorus, and myoglobin, the latter is responsible for the ARF that can occur with the syndrome. Myoglobin, an oxygen-binding molecule, contains a heme group and a globin group that disassociate into globin and ferrihemate when released into the circulation, especially in an acidic environment such as that of hypoperfusion. Myoglobin and myoglobin breakdown products, particularly in the presence of acidic urine (pH < 5.4), have a toxic effect on the renal tubules and react with the Tamm-Horsefall proteins in the renal tubules to form casts (Stewart, 2005). Recent literature implicates free radical formation as worsening cast-induced renal toxicity (Malinoski et al., 2004).

Compartment Syndrome as it pertains to crush syndrome: (week 9)

another complication of crush injuries is the development of compartment syndrome, (from nursing centre) which occurs when pressures increase within a fascia-encased region, classically a muscle group or the abdomen. The fascia provides a nonexpandable space, and, as fluid is sequestered, the pressure within the compartment rises. With the rise in pressure, the microvascular circulation is compromised leading to tissue ischemia. 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. Attempts should be made to intervene before there is a loss of pulses, an ominous finding that will almost always reflect irreversible tissue necrosis. Compartment syndrome may also occur in the abdomen. To monitor abdominal compartment syndrome, bladder pressures may be obtained through an indwelling urinary catheter. Pressures higher than 25 mmHg often warrant surgical decompression.

Return of circulation - Reperfusion injury as it pertains to crush syndrome: (week 9)

Return of circulation to the injured and ischemic area after rescue also results in injury, as reperfusion leads to increased neutrophil activity and the release of free radicals. Superoxide, the anion form of oxygen (O2-) and hydrogen peroxide (H2O2) react to form the hydroxyl radical ([middle dot]OH), which, in a large enough concentration, damages cellular molecules and causes a lipid peroxidation. Lipid peroxidation leads to cell membrane destruction and cell lysis (Civetta, Taylor, & Kirby, 1997). This damage leads to a further increase in the absorption of fluid, calcium, and sodium into the damaged cells. The amount of fluid that may be rapidly sequestered in the injured muscle can be equal to the extracellular volume of the patient, about 12 L in a 75-kg adult (Stewart, 2005).

Some or all of the following clinical signs and symptoms may be present: (from nursing centre) Cardiovascular instability Hypotension and hypovolemic shock. This may be caused from the massive fluid shift from the extracellular fluid space into the damaged cell s or associated injuries causing blood loss. Arrhythmia and negative inotropy secondary to hyperkalemia, hypocalcemia and hyperphosphatemia Cardiomyopathy Renal failure Secondary to circulatory shock and intravascular volume depletion leading to renal cortical ischemia. Release of myoglobin, urate, phosphate and purine by the muscle cells causes precipitation in the distal convoluted tubules, causing tubular obstruction. Metabolic acidosis with lactic acidosis Disseminated intravascular coagulopathy Hypothermia Myoglobinuria Skin injury and swelling Paralysis and paresthesia Pulses may or may not be present. Compartment syndrome Acute lung injury / ARDS

anoxia/hypoxia

Traumatic rhabdomyolysis, as it pertains to crush syndrome: (week 9)

Traumatic rhandomyolysis as it pertains to crush syndrome, (from nursing centre) results when muscle mass is compressed, causing direct injury to muscle fibers. As the tissue is compressed, it is deprived of blood flow and becomes ischemic, eventually leading to cellular death. The time to injury and cell death varies with the crushing force involved; however, skeletal muscle can often tolerate ischemia for up to 2 hr without permanent injury. In the 2- to 4-hr range, some reversible cell damage occurs, and by 6 hr irreversible tissue necrosis generally sets in. In addition to ischemic cell damage, direct injury from the crushing forces causes cell membrane failure and the opening of intracellular sodium and calcium channels. The opening of these channels results in the shift of calcium and sodium into hypoxic cells. This damages myofibril proteins and results in both worsened cell membrane dysfunction and the release of ATP-inhibiting nucleases. The resultant pressure-induced reduction in aerobic metabolism is further compounded by the ischemia of reduced blood flow.

Crush Syndrome V Compartment syndrome (week 9 - from orthopaedic trauma)

Compartment syndrome and crush syndrome are two closely related clinical entities. Both arise as a consequence of trauma to muscle, which results in swelling and a compromised circulation to muscles and nerves at the microvascular level. If reperfusion of the tissue isn't restored as quickly as possible, then tissue ischaemia may culminate in cell death and the crippling wholesale loss of muscle compartments. It may be useful to think of compartment syndrome in terms of a localised problem within an osteo-fascial muscle compartment. This is characterised by relentlessly worsening pain in the injured limb. The only effective treatment is fasciotomy which decompresses the ischaemic muscle, allowing it to be reperfused and so rescuing it from death. Fasciotomy is an emergency procedure! Crush syndrome may arise as a result of a neglected compartment syndrome or directly from severe injury. In crush syndrome the products of muscle cell damage lead to systemic problems which manifest as hyperkalaemia, acidosis, myoglobinuria, and renal failure. When a patient is freed from limb entrapment, reperfusion initiates this process; the most urgent danger is from hyperkalaemia leading to cardiac dysrhythmias and sudden death. Amputation can be life-saving if there are no means or resources to medically manage the hyperkalaemia and later renal failure. The decision whether to perform fasciotomies in crush syndrome is determined by the duration of ischaemia. If this is greater than 6-8 h, the muscle will not be rescued. The patients' compartments should be left closed, provided the life-threatening metabolic consequences of hyperkalaemia and myoglobinuria can be managed medically. If not, amputation should be performed swiftly.

Crush Syndrome (week 9)

Crush Syndrome is the systemic manifestation of muscle cell damage resulting from pressure or crushing.(from nursing centre) Initially described by Bywaters and Beall in 1941in a patient who initially appeared to be unharmed but subsequently died of renal failure. Crush Syndrome: Crush injury with systemic manifestations. Systemic manifestations are caused by a traumatic rhabdomyolysis due to muscle reperfusion injury when compressive forces on the tissues are released.This can cause local tissue injury, organ dysfunction, and metabolic abnormalities, including acidosis, hyperkalemia, and hypocalcemia.

Aeitology of crush injuries (week 9 - Crush injuries)

Crush injury A crush injury occurs when force or pressure is put on a body part. This type of injury most often happens when part of the body is squeezed between two heavy objects. Damage related to crush injuries include: Bleeding Bruising Compartment syndrome (increased pressure in an arm or leg that causes serious muscle, nerve, blood vessel, and tissue damage) Fracture (broken bone) Laceration (open wound) Nerve injury Infection (caused by bacteria that enter the body through the wound)

Hypovolemia, as it pertains to crush syndrome: (week 9)

Crush injury also causes hypovolemia by hemorrhagic volume loss and the rapid shift of extracellular volume into the damaged tissues.(from nursing centre) Acute renal failure (ARF) is caused by hypoperfusion of the kidneys, which normally receive 25% of cardiac output (Lameire, 2005). This hypoperfusion compounds the toxicity caused by cast formation and mechanical blockage of the nephrons by myoglobin, and underscores the importance of early, vigorous volume resuscitation to improve urine flow, which dilutes and clears toxins.

Key Management points of Crush Syndrome; Crush Injury (week 9)

Key management points (from cancer therapy advisor) Primary survey with focus on airway, breathing and circulation. Establishing intravenous access and initiation of fluid resuscitation prior to releasing the crushed extremity, especially if the time of entrapment is > 4 hours. If extrication is impossible short-term use of tourniquet on the affected limb is recommended until intravenous access can be obtained. Acute limb amputation should be avoided until extrication is impossible. Continue with fluid resuscitation while transfer to a medical facility is initiated. Monitor the crushed limb for the 5 P's: Pain, Pallor, Paresthesia, Pain with passive movement and Pallor. Combat hypotension with aggressive hydration. Prevention of renal failure is important. Alkaline diuresis and mannitol therapy is recommended. Hemodialysis is also recommended for acute renal failure. Electrolyte abnormalities (hypokalemia / hypocalcemia / hyperphosphatemia) need to be monitored and treated accordingly. Monitoring for cardiac arrhythmia is recommended. Correction of acidosis with alkalinization of the urine is critical. Monitoring for compartment syndrome is also recommended. If present it should be treated with fasciotomy. Fasciotomies should not be performed if the compartment syndrome has been present for > 24 hours. Open wounds should be treated with antibiotics, tetanus toxoid and debridement of necrotic tissue. Hyperbaric oxygen therapy may be useful.
