|
Reasons for inadequate plane of anesthesia |
Oxygen flow rate is too low Incorrect vaporizer setting Incorrect placement of ET |
|
Name some colloid solutions |
Hetastarch Dextran Plasma |
|
True or False? Laryngospasm is more common in the dog than in the cat |
False |
|
True or false? Bradycardia can always be treated with anticholinergics |
False |
|
True or false? Patients with renal disease are especially susceptible to dehydration, overhydration, hypotension, and electrolyte imbalance |
True |
|
True or false? Obese animals require lower drug doses on a per kg basis |
True |
|
Brain damage may occur when there is inadequate oxygenation of the tissues for longer than_____________minutes |
Five |
|
A geriatric patient is considered to be one that has reached _______________ of its life expectancy |
75% |
|
You may suspect the pop-off valve is malfunctioning if ........ |
Reservoir bag is distended with air Patient has difficulty exhaling |
|
Most anesthetic problems & emergencies are caused by____________? |
Human error Equipment related issues Adverse effect of anesthetic agent Increased patient risk |
|
If a problem is suspected with the ET, you should check it in what 2 ways? |
-Attempt to bag the patient and see if the chest rises. -Disconnect the animal from the machine and feel for air coming out of the tube when the chest is compressed. |
|
TIVA Total intravenous anesthesia |
Patient is induced to effect, additional boules are admininstered every 3-5 min to maintain |
|
TIVA by CRI |
Patient is induced to effect, and anesthesia is maintained by constant infusion via a syringe pump |
|
General anesthesia via inhalant is: |
Faster than IM but slower than IV |
|
Most commonly used method of inducing and maintaining anesthesia in small animals: |
IV induction with inhalant maintenance |
|
Calms the patient & prepares them for anesthetic induction |
Pre-med or sedation (tranquilizer, opioids, alpha 2 agonists) |
|
Example of drugs used for IV induction: |
Ketamine & diazepam Propofol |
|
Complications of induction chamber? |
Stress, trauma, vomiting, exposes personnel to waste gases |
|
What size patients would you use the induction chamber for? |
<5-7kg body weight |
|
Materials needed for intubation |
3 ET's of slightly different sizes Gauze 12mL syringe Stylette Lidocaine Laryngoscope Lubricant |
|
Appropriate length of the ET? |
Must reach the thoracic inlet and not extend beyond the muzzle |
|
When an animal scheduled for a surgical procedure is brought in by a neighbor who is in a hurry, the best thing to do is: |
Have the neighbor sign the consent form and call the owner before before the procedure is initiated |
|
You are about to use the anesthetic machine and notice that the flow meter is working, but the pressure gauge on the oxygen tank reads close to zero, the best thing to do is....? |
Change the oxygen tank |
|
While monitoring a patient on the anesthetic machine, the oxygen tank has become empty. The best thing to do is....? |
Disconnect the patient from the circuit, put on a new oxygen tank, then reconnect the patient to the circuit |
|
If the pop-off valve is inadvertently shut, it will__________? |
Cause a significant rise of pressure with in the circuit |
|
True or False? Respiratory arrest is always fatal |
Flase |
|
What are some signs that the ET is malfunctioning even if it is in the trachea? |
-The animal is Dyspneic -compression of the reservoir bag does not result in raising of the chest -cannot be kept at an adequate plane of anesthesia -the reservoir bag is not moving or it is moving very little |
|
Why are brachycephalic dogs at increased anesthetic risk? |
Excess tissue around the oropharynx Increased vagal tone Small trachea in comparison with body size |
|
How would you decrease risk with a brachycephalic dog? |
Use atropine Pre-oxygenate before giving anesthetic Use injection anesthetic Intubate immediately after induction |
|
Why are animals under anesthesia at increased risk during c-section? |
Decreased resp. Function Increased chance of aspirating vomit Increased chance of hemorrhage Increased workload of heart |
|
Tachypnea may result from ....? |
Increased levels of arterial Co2 Inadequate plane of anesthesia |
|
Name some possible equipment issues |
Using the wrong vaporizer Using 2 vaporizers at one Pop off valve not open |
