Multiple Organ Dysfunction Syndrome (MODS) Flashcards
is altered organ function in an acutely ill patient
that requires medical intervention to support
continued organ function.
isn’t an illness itself; rather, it’s a
manifestation of another progressive, underlying condition
Multiple organ dysfunction syndrome (MODS)
■ Multiple trauma
■ Massive infection or sepsis
■ Hemorrhage or shock
■ Surgical complications
■ Acute pancreatitis
■ Burns, extensive tissue damage, and/or necrotic
tissue
■ Aspiration
■ Multiple blood transfusions
■ Inadequate fluid resuscitation
Those at high risk for developing MODS
Clinical manifestations two patterns:
which occurs most often when the initiating event is a
pulmonary one such as lung injury, the patient experiences
respiratory compromise that necessitates intubation. This
usually occurs within 72 hours of the initiating event.
- organ or organ system failure is due to a
direct injury such as trauma or a primary disorder that
usually involves the lungs, such as pneumonia, aspiration,
near drowning, and pulmonary embolism.
Primary Mods
• It occurs most often in the patient with septic shock and
progressively unfolds over about 1 month.
• The patient also experiences respiratory failure and requires
intubation.
• The patient remains hemodynamically stable for about 7 to 14 days.
• Despite this apparent stability, the patient exhibits a hypermetabolic
state characterized by hyperglycemia, hyperlacticacidemia, and
polyuria.
• The metabolic rate is 1.5 to 2 times basal metabolic rate.
• During this stage, there is a severe loss of skeletal muscle mass
(autocatabolism).
• The organ system failure is due to sepsis.
Secondary MODS
- Vasodilation and decreased PVR with normal BP
- CO increases to maintain BP
- Hypovolemia due to capillary permeability &
interstitial fluid loss - Skin: warm, pink & dry
- Chills & body temp.
- Hyperventilation
- resp. alkalosis
Assessment of
Early MODS
- Hypotension
- Weak thready pulse
- ECG: ST & T – waves changes (myocardial
perfusion) - Skin: cold, moist, pale, mottling cyanosis
- Hematologic alterations
- Hypoxia
- Metabolic acidosis
Assessment:
Late MODS
