GDV & Shock Flashcards
What does GDV stand for?
Gastric Dilstion Vulvulus
Explain what’s happening in GDV
- Stomach bloats & twists
- Blocks off both the pylorus & oesophagus, trapping gas in the stomach
- Stomach expands more , pressing on the vena cava restricting blood flow to the heart
- Spleen gets compressed
- Lining of stomach gets so tight that it restricts blood flow
What triage assessment is done when a patient arrives?
ABCD
MBS
Signs / symptoms of GDV
- unproductive vomiting
- retching
- bloated stomach
- restlessness
- hypersalivation
- collapse
Physiological event during GDV that can cause death
1) Poor circulation
2) Risk of necrosis
3) Cell death & anaerobic muscle function
What does lactate measure? How does it help with treatment?
Lactate levels in the blood stream.
Guide to improve perfusion with IVFT
How does a radiograph identify GDV? Common image?
The Popeye Arm image
Explain reperfusion
When circulation is restored after same time of being poor, the toxin build up during anaerobic energy is released into the circulation systemically and cause tissue damage due to inflammatory response
What is happening in the cardiovascular system during a hemorrhage?
- CVS vasoconstriction to help with BP
- The heart speeds up to help with BP
- Pulses become weak as blood is concentrated to major organs NOT peripheral areas
- Pale MM, slow CRT, weak pulses, fast HR
What’s the major concern when a patient is in shock?
Oxygen to the cells and organs
Name 4 types of shock
1) Distributive
2) Obstructive
3) Cardiogenic
4) Hypovolaemic
What type of shock does hemorrhage cause?
Hypovolaemic
What type of shock does sepsis cause?
Distributive
Why is it important to warm cats during IVFT?
Cats are hypothermic.
This slows down HR & reduces cardiac output
Warm up cat at the same time to increase HR and cardiac output. Also better O2 delivery to tissues
What’s the crystalloid shock fluid rate for cats?
40-60ml/kg
