Collapse And GDV Flashcards
What are the four catorgories for mentation
Alert
Stupor (drunk)
Obtunded (lethargic)
Comatose (not responsive)
What happens anatomical when a GDV occurs
Stomach bloats and twists blocking pylorus and oesophagus trapping gas.
Stomach expands restricting blood flow to vena cava of heart
Spleen get squashed and blood flow restricted
Stomach lining gets so tight that blood flow is restricted
Symptoms of GDV from owner
Unproductive vomiting Retching Bloating Restless Collapse Hypersalivation
What are the physiological events that can happen during GDV that can cause death of untreated
Poor circulation due to compressed vena cava
Tissue necrosis
Anaerobic muscle function
What will you see on a physical exam for GDV
Pale MM Slow CRT Tachycardia Arrhythmia Tachypnoea Hypersalivation Hypovolemic shock
What is the treatment for GDV
Fluids Analgesia Corticosteroids to treat rep injury Gastric decompression X-ray Surgery gastroplexy
What can reperfusion lead to ?
SIRS
MODS
DIC
What is reperfusion?
The restoration of blood flow to organ or tissue
What are common diagnostics used for GDV
Lactate
X-ray
Bloods- PCV, glucose, clotting time
What are the checks for cardiovascular assessment
Pulses rate and quality MM CRT HR Pulse deficit Rythm Extremities temp
Describe what reperfusion injury is
Tissue is deprived from oxygen, uses anaerobic energy and lactic acid builds. Inflammatory mediators are then produced.
When blood flow returns this lactic acid does through circulation. This damages DNA and other cells. Can also cause cell death.
It speeds up rush of WBC to area and the system gets overloaded by inflammatory cells.
What is the emergency fluid rate and type for a GDV
90ml/kg
Crystalloid
Why do we get lactic acidosis with GDV
Because we have tissue which is not receiving oxygenation and lactic acid is building up
