Flashcards in Chpt. 8 - Key Points Deck (18):
1

Small animal patient restraint and anesthesia

IV or mask induction followed by maintenance with an inhalant agent is most common.

2

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

3

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

4

Why must equipment be carefully prepared before anesthetic induction?

Once induction commences, the anesthetist has little to no time to gather missing equipement.

5

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.
This requires:
- finesse
- watchfulness
- an ability to make decisions rapidly
- an ability to act quickly based on PT monitoring parameters

6

Titration

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)

7

Mask and chamber inductions

- involve risks the anesthetist must be aware of to prevent serious complications
- vigilant PT monitoring is required

8

Why is endotracheal intubation justified even in PTs anesthetized only with injectable drugs?

Because there are many advantages to ET intubation.

9

What does successful and safe ET intubation require?

- careful preparation
- excellent technique
- watchfulness for potential complications

10

What is the anesthetic period divided into?

- Preanesthesia
- Induction
- Maintenance
- Recovery

11

Name the anesthetic depth deemed suitable for most surgical procedures.

Stage III, plane 2

12

Why is PT positioning, comfort, and safety so important during anesthetic maintenance?

To avoid problems such as:
- traumatic injury
- accidental overdose
- airway blockage
- hypoxemia
- circulatory compromise
- burns
- hypostatic congestion
- corneal drying

13

Name two of the many factors affecting the length of the recovery period.

- the anesthetic protocol
- the PT's condition

14

Return to consciousness is accompanied by?

- increasing HR
- increasing RR
- increased reflex responses
- voluntary movement

15

Recovery period

- 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

16

Extubation in dogs and cats

Dogs:
- when swallowing reflex returns
Cats:
- PT shows signs of impending arousal, such as voluntary movements, swallowing, or active reflexes

17

Other duties during recovery

- stimulation of PT
- administration of oxygen
- postoperative analgesia
- general nursing care

18

How to improve anesthetic safety

- use preanesthetic agents
- use of minimum effective dosages
- selection of a protocol well suited to PT
- close monitoring of PT
