Study Notes

Thiopentane

Thiopentane is an example of a very short-acting barbiturate.
Barbiturates are effective as anxiolytics, hypnotics, and anticonvulsants.
Barbiturates have weak analgesic effects, preventing their sole use during surgery.
Thiopentane can be used as a sedative.

Negative Effects of Barbiturates

Prolonged recovery time.
Inadequate analgesic properties.

Induction of Anesthesia

Examples include thiopentone and ketamine.

Maintenance of Anesthesia

This involves the recovery phase, during which the animal will go through the stages of anesthesia in reverse.
The recovery stages will be slower than during the induction phase.
This allows for the examination of each stage more easily.

Changes to Look for During the Experiment:

Observe the animal for changes during the different stages of anesthesia.
Monitor any changes that occur during the recovery phase.
