Flashcards in Chpt. 8 - Key Points Deck (18):
Small animal patient restraint and anesthesia
IV or mask induction followed by maintenance with an inhalant agent is most common.
When a protocol is being selected, great care must be used in?
- calculating drug dosages
- calculating oxygen flow rates
- calculating fluid administration rates
- drawing up and administering anesthetic agents and adjuncts
To safely and effectively anesthetize a PT, the anesthetist must have a clear understanding of what?
- the expected sequence of events and dynamics associated with each anesthetic technique
Why must equipment be carefully prepared before anesthetic induction?
Once induction commences, the anesthetist has little to no time to gather missing equipement.
What is the goal of anesthetic induction and how is it achieved?
The goal is to take the PT from consciousness to stage III anesthesia smoothly and rapidly.
- an ability to make decisions rapidly
- an ability to act quickly based on PT monitoring parameters
A process of giving IV induction agents "to effect".
(when inducing anesthesia by IV injection, in general the entire calculated dose should not be administered at once)
Mask and chamber inductions
- involve risks the anesthetist must be aware of to prevent serious complications
- vigilant PT monitoring is required
Why is endotracheal intubation justified even in PTs anesthetized only with injectable drugs?
Because there are many advantages to ET intubation.
What does successful and safe ET intubation require?
- careful preparation
- excellent technique
- watchfulness for potential complications
What is the anesthetic period divided into?
Name the anesthetic depth deemed suitable for most surgical procedures.
Stage III, plane 2
Why is PT positioning, comfort, and safety so important during anesthetic maintenance?
To avoid problems such as:
- traumatic injury
- accidental overdose
- airway blockage
- circulatory compromise
- hypostatic congestion
- corneal drying
Name two of the many factors affecting the length of the recovery period.
- the anesthetic protocol
- the PT's condition
Return to consciousness is accompanied by?
- increasing HR
- increasing RR
- increased reflex responses
- voluntary movement
- anesthetist must continue to monitor PT's vital signs (particularly temperature) as anesthetic complications commonly occur during this period
- administer oxygen for several minutes after anesthetic has been discontinued
Extubation in dogs and cats
- when swallowing reflex returns
- PT shows signs of impending arousal, such as voluntary movements, swallowing, or active reflexes
Other duties during recovery
- stimulation of PT
- administration of oxygen
- postoperative analgesia
- general nursing care
