What is the difference between centralized vs decentralized?
Centralized-support, care and use areas are adjacent to animal housing. This method is cheaper, has more efficient flow, there is less duplication, less transport and has greater security and bio-security.
Decentralized animal housing and use is not sole use of space or physically separated from support areas.
A reversible state characterized by a loss of feeling or sensation.
What are 3 types of anesthesia?
General - absences of pain sensation over entire body

Regional - loss of sensation in an anatomical area supplied by a particular nerve.
Decreased perception of pain without the loss of consciousness
State of calmness without loss of consciousness
localized sensation of discomfort resulting from the stimulation of specialized nerve endings.

Which injectible agent provides poor muscle relaxation and mild analgesia at low levels. It is usually combined with other agents to enhance its effects. It causes increased blood pressure, heart rate and respiratory rates.
Which injectible agent is a CNS depressant with minimal muscle relaxation and analgesia at low doses. It can cause decrease in heart and respiratory rates.
Which inhalant anesthetic is a volatile liquid, provides quick induction and recovery, mild respiratory depression. It is not a good muscle relaxant and is a poor analgesia at sedative levels
Which inhalant anesthetic is a gas at room temperature, is not capable of anesthesia by itself but can be given with other anesthetics,
has rapid effect and recovery with minimal CV effects. It is good for muscle relaxation and must be used in combination with oxygen.
When monitoring and providing support for anesthesia you should look at

What is the difference between Major and Minor survival surgery?
Major survival surgery penetrates or exposes a body cavity or produces substantial impairment of physical or physiologic function.
Minor survival surgery does not expose a body cavity and causes little to no physical impairment.
What is the difference between survival and non survival surgery?
Survival surgery the animals is expected to recover. Non survival surgery the animal is euthanize once the procedure is complete.
What is the main difference between rodent surgical guidelines and non-rodent surgical guidelines?
In non-rodent species, the surgeon is required to wear surgical gown, cap, mask and shoe covers.
