Anesthesia Lecture 4 Flashcards
Fluids during surgery for a dog and cat
Dog= 5 mL/kg/hr; Cat= 3 mL/kg/hr
Maintenance fluids for a dog and cat
Dog= 2-6 mL/kg/hr; Cat= 2-3 mL/kg/hr
The most reliable sign of inadequate anesthetic depth
Responsive movement
What can cause an increase in respiratory rate?
Sx stimulation, increased CO2, and Soda lime exhaustion
Always assume the patient is…
Too deep
Normal heart rate for dogs and cats
Dog= 60-180 bpm; Cat= 120-240 bpm
Perfusion can be measured by…
Blood pressure, CVP, MM color/CVT, and pulse strength
Normal systolic pressure in dogs and cats
110-10 mmHg
Normal diastolic pressure in dogs and cats
50-70 mmHg
When the blood pressure drops below normal, what should be done?
Increase the fluids
MM color is pale
Poor perfusion/blood loss/ decreased O2
Cyanosis
Hypoxia, poor perfusion
1 fully soaked gauze sponge=?
5 mLs of blood
Replace every 1 mL of blood loss with __ mLs of ___
3 mLs of crystalloids
Respirations under anesthesia for dogs and cats
8-12 bpm
Doing this every 5 mins can help prevent atelectasis
Giving a positive pressure ventilation
Dyspnea
Patient is too deep, kink in ET tube, or obstruction of tube
Rocking boat
These are jerky respirations and are due to the patient being too deep
Apneustic breathing
Can be caused by ketamine
Pulse oximeter measures…
The oxygen saturation of hemoglobin in the blood
Normal values when using a pulse oximeter
95%
Capnograph
A way to monitor expired Co2
Normal capnograph readings for dogs and cats
35-45 mmHg
Hypercapnea
The capnograph is greater than 40 mmHg
