Mechanisms of Anesthesia.. Oxygen + anesthetic into rebreathing bag Animal breathes in via rebreathing bag Capillaries exchange Oxygen and anesthetic into bloodstream Anesthetic reaches the brain

A normal anesthetic event Preanesthetic Anesthetic Induction of anesthesia Intubation Maintenance Extubation Recovery

Recovery Normal excitement phase Keep quiet and safe Monitor TPR, attitude Keep warm Monitor any surgical incisions

Preparation: Endotracheal tube: What is it?? What does it do?? Check for: Correct size Check cuff

Rebreathing Tubes What are they? What is their function? Choose: size Non-rebreathing set up

Other options… Anesthesia Mask Induction Chamber

Rebreathing Bag Reservoir of anesthetic gas and oxygen Need to choose correct size based on weight or ideal weight of patient

Laryngoscope What is it? What is it’s purpose? Check for: size, lightbulb, function

Vaporizer What is it? What does it do? Preparation: fill it

Oxygen Supply Anesthesia travels via Oxygen Flowmeter determines amount of oxygen flowing into system Check tank every time you use machine SAFETY TIP: Always turn OFF the Oxygen when you are finished

Scavenge System What does it do? OSHA requirements F/AIR vs Scavenge system

Other necessities… Gauze tie Heated table/ heating pad Eye lube Syringe for cuff of ET tube

YOUR JOB….. BE PREPARED!! Monitor animal Adjust anesthesia Give breaths Recover patient
