Q

What is a common postoperative issue associated with hepatic disease?

A

Longer recovery time

Patients with hepatic disease often experience prolonged effects from anesthesia, leading to extended recovery periods.

Q

Why is it very important to do PAB on a blocked cat prior to administering any sedation?

A

Blocked cats can lead to kidney damage, as the kidneys filter drugs and work with the liver to metabolize drugs and maintain electrolyte balance.

Hyperkalemia in these patients can lead to cardiac arrest.

20
Q

What can happen to blocked cats depending on how long they have been blocked?

A

They can experience kidney damage.

Kidney damage occurs because kidneys are responsible for filtering drugs and maintaining homeostasis.

21
Q

What is a significant risk for very hyperkalemic patients?

A

They can go into cardiac arrest.

Hyperkalemia refers to elevated potassium levels, which can affect heart function.

22
Q

What is one thing that is done differently for C-sections pre-op compared to other procedures?

A

Do as much as possible prior to any sedation being given.

This approach benefits both the mother and the young by minimizing drug exposure.

23
Q

What are some pre-operative actions that can be taken for C-sections before sedation?

A

Shave belly, place IV catheter, pre-oxygenate.

These actions help prepare the mother for surgery while reducing the need for sedation.

24
Q

What should be checked to ensure proper anesthesia during surgery?

A

Vaporizer, % level of agent, oxygen levels, ET tube placement, rebreathing bag movement

These checks help monitor the anesthetic state of the animal.

25
True or False: An animal may move in response to surgical stimulation.
True ## Footnote Movement can indicate insufficient anesthesia or response to pain.
26
Fill in the blank: The _______ should be checked for movement to assess proper ventilation.
rebreathing bag ## Footnote The rebreathing bag is critical for monitoring the animal's respiratory function.
27
What is the purpose of checking the vaporizer during surgery?
To monitor the % level of anesthetic agent being delivered ## Footnote Proper levels are essential for maintaining anesthesia.
28
What should be confirmed about the ET tube during surgical procedures?
It should be in place ## Footnote Proper placement ensures secure airway management.
29
What vital sign should we always keep a close eye on during surgery?
Blood pressure ->80 systolic is great!
30
Is an SpO2 reading below 95 acceptable?
No
31
How can we check if an SpO2 reading is accurate?
CRT, gums, tongue - pink & moist?
32
What are the 3 main reasons why an animal is too deep under anesthesia?
* Anesthetic overdose * Pre-existing problem * Hypothermia
33
What is the first thing you should do when you notice something is wrong in the surgery suite?
Tell the vet ## Footnote Immediate communication is crucial for patient safety.
34
What is the first step in the process of bagging a patient?
Close pop off valve all the way ## Footnote This prevents air from escaping during the bagging process.
35
What should you monitor while bagging a patient?
Watch bag fill up ## Footnote Ensuring the bag inflates properly indicates effective ventilation.
36
What is the appropriate pressure range to maintain while bagging a patient?
15-20 mmHg ## Footnote This pressure range helps avoid barotrauma and ensures adequate ventilation.
37
How often should you repeat the bagging process as needed?
Every 5 seconds ## Footnote Regular intervals help maintain adequate ventilation without overinflating the lungs.
38
What should you remember to do at the end of the bagging process?
Open pop off valve ## Footnote This allows for the release of excess pressure and prevents damage to the respiratory system.
39
Can neonate patients have the same dosage of injectable drugs as healthy adults?
No, they need ½ to ⅓ of the normal dose ## Footnote Neonates cannot metabolize drugs effectively due to immature liver function.
40
Why do neonate patients require a lower dosage of injectable drugs?
They can't metabolize drugs within the liver as it's not fully mature ## Footnote This immaturity affects their pharmacokinetics and pharmacodynamics.
41
What should be done if an animal won't stay anesthetized?
Bag the patient ## Footnote This refers to manually ventilating the patient to ensure adequate oxygenation.
42
What is a potential reason for apnea or shallow respirations in an anesthetized animal?
Poor vaporizer function ## Footnote This may indicate that the anesthetic delivery system is not functioning correctly.
43
What is the minimum oxygen flow rate recommended for anesthetized patients?
500 ml/min ## Footnote Ensuring this flow rate helps maintain proper oxygenation during anesthesia.
44
What should be checked if patients routinely wake up during anesthesia?
Poor vaporizer function ## Footnote This can lead to inadequate anesthesia and cause the patient to wake up.
45
What are two critical factors to ensure correct anesthesia delivery?
Correct machine assembly and tight connections ## Footnote This is essential to prevent leaks and ensure effective delivery of anesthetic gases.
