Monitoring Anesthesia And Post-anesthetic Period Flashcards
What should you know about camelid/ruminant recovery from anesthesia?
They are prone to regurgitating so you should:
keep them incubated until they are swallowing
keep head elevated
Why is phenylephrine given to horses in the post-Anesthetic period?
To open nasal airways
What is a main goal of equine anesthesia?
To decrease inhalant concentration as much as possible
What two things may manually help with equine anesthetic recovery?
Tail rope
Halter rope
What are some negative effects of post-operative pain in horses?
Increased cardiac load Increased cardiac oxygen demand Delayed healing Hypoventilation Ileus Water retention Excitation
How does pulse oximetry (SPO2) work?
Red and infrared lights are used to measure the oxyhemoglobin and reduced hemoglobin in the blood (they have different light absorptions)
Where should you place an SPO2 probe?
Tongue, lips, vaginal mucosa, prepuce, base of tail, rectum
Why should you carefully assess pulse ox (SPO2) readings?
They can sometimes be misleading as to the ventilation of the patient
SPO2 will plateau at 100% Hb saturation
When a patient is getting 100% oxygen, SPO2 should be 400-600
However, if the patient is receiving 100% oxygen and is only at 80-100, it will have complications in recovery
What value is ideal for SPO2 reading?
> 93
How does temperature affect anesthetic requirement?
Hypothermia will decrease anesthetic requirement
Hyperthermia will increase anesthetic requirement
What is the ideal size of a blood pressure cuff?
Width of cuff should be 40-60% circumference of limb
What are two types of capnographs?
Mainstream
Side stream
What are the main benefits of capnography?
Can confirm intubation
Monitor for cardiac arrest, hypovolemia, malignant hyperthermia, change in metabolic rate
What does a capnograph measure?
End tidal CO2
What monitor changes would you see with vasodilation?
Mostly normal with decrease in BP
