ASSIGNMENT 5.3    PREANESTHETIC CALCULATIONS
Your first patient today is a 9 year old FS English Cocker Spaniel.  She is scheduled for a bilateral total ear ablation.  Her weight is 38 lbs.  Physical examination is unremarkable other than severe hyperplasia of both ear canals.

1. What is a total ear ablation?
2. What diagnostic tests might be requested for this patient and why?

The veterinarian informs you propofol (10 mg/mL) at a dosage of 4 mg/kg IV will be used as the induction agent for this patient. She will receive 0.04 mg/kg acepromazine IM 20 minutes prior to induction and she will receive an IV bolus of fentanyl (0.05 mg/mL) at a dosage of 0.004 mg/kg followed by a CRI of 0.001 mg/kg/hr during the procedure.

3. Calculate and administer the acepromazine dose.

4. a. What are the benefits of using acepromazine.
b. When should acepromazine be used with caution?

 

c. Do you need to log this drug out?

 

d. Does acepromazine provide any analgesia?

 

He also asks you to calculate the dose of an anticholinergic in case it is needed during surgery.

5. Why would an anticholinergic be needed?

 

6. Which anticholinergic would you use?    Calculate the dose.

Atropine  0.022 mg/kg         0.54 mg/mL

Glycopyrrolate 1 mL/40 lbs.        0.2 mg/mL

 

a. What benefits does an anticholinergic provide?

 

b. If the patient became bradycardic during surgery, which anticholinergic  would be appropriate?

c. Do anticholinergics provide any analgesia?

 

d. Do you need to log them out?

 

calculate the fluid rate and prepare all the equipment for administration of the fluids and CRI.

6. What IV fluid will you get from the storeroom?

 

7. What materials do you need to prepare?

8. Calculate the flow rate. (The surgery fluid rate is 10 mL/kg/hr 
    not 50 mL/kg/day our patient should not       have a deficit or ongoing loss)  

9. Calculate the dose of propofol you need to draw.

 

10. Calculate the bolus dose of fentanyl.

 

11. Calculate the CRI for fentanyl and explain how you would administer this.

      a. Why is fentanyl being used?
