1. Acute blood loss
2. IMHA
3. Chronic anemia -
Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.6 Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.6
Acute Blood Loss Anemia
-Healthy animals can tolerate <= 20% loss of blood volume
-Peracute blood loss may have normal PCV for hours...only indication is low TS
-Many animals will have normalization of organ perfusion with crystalloids alone -
Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.7 Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.7
Increased Destruction
-Hemolytic anemias
-pRBC are lifesaving
-No evidence that blood adds "fuel to the fire"
-No evidence that transfused cells are destroyed more rapidly than patient's cells -
Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.8 Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.8
Decreased Production
-Bone Marrow Directed Anemia
- Destruction of RBC precursors in the marrow
- Pure red cell aplasia
- Erythroid maturation arrest
- Bone marrow directed IMHA
-Slow drop in PCV associated with a subtle onset of clinical signs
-Transfused RBC have near normal RBC lifespan
- 110 days in dogs
- 70 days in cats -
Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.9 Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.9

- HLA proteins and immunologically active donor WBCs
--> immunosuppression
- Cellular factors from deteriorating donor WBC -->
endothelial cell and neutrophil activation
- increased incidence of infection in transfused ICU patients
- Transfused transplant patients have improved outcome -

-Hemolytic transfusion reaction
-Infectious transfusion reactions -
Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.66 Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.66
Non Hemolytic Febrile Transfusion Reaction
-Most common transfusion reaction identified
-Occurs within minutes to hours of receiving transfusion
-Usually mild and self limiting
-Likely due to leukocytes and cytokines
- Leukoreduced RBC reduce incidence of febrile
transfusion reactions but not common practice in the US -
Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.67 Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.67
Hemolytic Transfusion Reaction
-Due to donor-recipient incompatibility
- Minimized by blood typing all recipients
- If indicated, major and minor crossmatching will indicate incompatibility prior to transfusion
-Due to previous sensitization
- Knowing past transfusion history is critical - Antibodies form in 4-5 days from 1st transfusion -->
crossmatch required with all subsequent transfusions -
Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.68 Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.68
Hemolytic Transfusion Reaction
-Due to donor-recipient incompatibility
1. Canine patient with past transfusion history that was not
crossmatched
2. Any cat that was not blood typed before transfusion
3. Cat receiving type-specific blood that has Mik-antigen incompatibility
-As little as 1 ml of incompatible blood can potentially
cause fatal hemolytic transfusion reaction
- Blood typing is critical, especially in cats
- Type B cats have strong anti-A antibodies
- Incompatible transfusion is fatal -
Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.69 Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.69
Infectious Transfusion Reactions
-Contaminated blood units
- Out of date
- Incorrect storage temperature
- Non sterile collection technique
- Blood bag sterility compromised
-Donor with infectious disease
- Incomplete donor infectious disease testing
- Not receiving heartworm prevention monthly
- Not up to date on vaccinations -

Recognizing Transfusion Reactions
-Febrile Non-hemolytic transfusion reactions
- Signs
- Fever
- Vomiting
- Urticaria
- Pruritis
- Most commonly respond to slowing the transfusion rate
- May require diphenhydramine, less commonly steroids -

Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.72 Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.72
Action Step
Febrile Non-hemolytic transfusion reactions
- Slow rate of transfusion
- If temperature normalizes or stabilizes then can continue transfusion
- If temperature continues to rise, stop transfusion temporarily
- If temperature stabilizes, continue transfusion at a slower rate
- If temperature continues to rise, STOP transfusion and submit blood for a bacterial culture and gram stained blood smear to rule out bacterial contamination -
Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.73 Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.73
Action Step
Non-hemolytic transfusion reactions
- Vomiting, urticaria, pruritis
- Slow rate of transfusion
- Administer 1-4 mg/kg diphenhydramine IM/SQ
- If clinical signs resolve, continue transfusion at current rate
- If clinical signs continue, try slowing transfusion even further - If signs resolve, continue transfusion
- If signs continue, consider repeating diphenhyrdamine or administering corticosteroids - No data to support use of steroids to treat non hemolytic transfusion reactions -
Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.74 Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.74
Recognizing Transfusion Reactions
-Acute hemolytic transfusion reaction

- Pyrexia
- Hypotension
- Hemoglobinemia, hemoglobinuria -
Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.75 Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.75
Action Step
Acute hemolytic transfusion reaction
- Stop the transfusion immediately
- Submit blood (pre-transfusion) from recipient and blood from donor bag to reference lab or complete in house testing to confirm type/ crossmatch
- Monitor recipient closely with serial PCVs as hemolysis can be severe
- Perform new blood type and crossmatch before another transfusion is administered -
Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.76 Transfusion in Practice Part 1: Treatment of Anemia and Blood Bank Management - P.76
Recognizing Transfusion Reactions

- Extravascular hemolysis occurring 3-21 days after
transfusion
- Drop in PCV sooner than expected
- New hyperbilirubinemia
- New hyperbilirubinuria
-Usually no specific treatment required -

Types of Pain
-Acute – serves a protective role by enabling healing and tissue repair and usually is considered to end within 3months. Muir WW and Woolf CJ. Mechanisms of pain and their therapeutic implications, JAVMA, 2001, 219(10):1346-1356-Chronic – induces biochemical and phenotypic changes in the nervous system that escalate and alter sensory inputs, resulting in physiologic, metabolic, and immunologic alterations that threaten homeostasis and contribute to illness and death.Maier SF, Watkings LR. Cytokines for psychologists: implications of bidirectional immune- to- brain communication for understanding behavior, mood, and cognition. Psychol Rev 1988;105: 83-107
-Neuropathic – is a maladaptive phenomenon caused by pathologic neuroplasticity and can become a disease of the neurologic system by persisting beyond resolution of an inciting cause. Von Hehn CA, Baron R, Woolf CJ. Deconstructing the neuropathic pain phenotype to reveal neural mechanisms. Neuron, 2012 73:638-52.

Some detrimental effects associated with inadequate pain management (Orskov, 2010)
Altered Mentation
Reduced Appetite
Reduced Immune Function
Prolonged Recumbency
Altered Physiological Parameters
Unnecessary suffering
e.g. anxiety, dullness, aggression
weight loss and tissue breakdown for energy
e.g. Cortisol: tissue breakdown and delayed wound healing
increased risk of wound infections
ischemia, vascular thrombosis, urinary / fecal retention
e.g. lick granulomas
interference with patient assessment

World Small Animal Veterinary Association (WSAVA) Tenets of Pain Assessment and Recognition (Mathews, Kronen, Lascelles et al, 2014)
-Pain assessment should accompany every patient assessment
-Treat predictable pain – pain associated with surgery is 100 predictable
-Pain assessment is key to determining the degree and duration of pain treatment but should not replace the adage of treating predictable pain
-Perioperative pain extends beyond 24 hours and should be managed accordingly
-Practice preventive (preemptive) pain management – initiate appropriate treatment before a procedure to prevent the onset of pain, and continue this to prevent occurrence of pain for the duration of time commonly recommended for the problem or which the patient requires
-Response to appropriate treatment is the gold standard to measure the presence and degree of pain. -

Who
-Use NSAIDs in their practice?
-Dogs?
-Cats?
-Other?
-Themselves? -
NSAIDs: What We Do Know - P.4 NSAIDs: What We Do Know - P.4
NSAID
-Non Steroidal Anti Inflammatory Drug
-Historically for mild, chronic pain
-Humans – classically associated with GI side fx
-Hippocrates showed medical benefits of willow bark
-1971 – Aspirin proposed mechanism of action realized -
NSAIDs: What We Do Know - P.5 NSAIDs: What We Do Know - P.5
What's special about them?
-Potent anti-inflammatory
-End result similar to steroids
-Prostaglandin production decreased
-Central and peripheral effects
-Analgesic
-Antipyretic
-Non-dependence
-Devoid of opioid side fx -
NSAIDs: What We Do Know - P.6 NSAIDs: What We Do Know - P.6
Generalizations of NSAIDs
-Rapidly absorbed by the GI
-Highly protein bound
-Weak acids – accumulate in inflamed tissue
-Metabolized in the liver +/- enterohepatic cycling
-Half lives vary from 2-72 hours
-Effects differ in half life and route of admin -

Where’s the action?
ARACHIDONIC ACID
Lipooxygenase
Leukotrienes
Bronchospasm Inflammation
COX-1
Prostaglandin
Gastric Protection uterine contraction,renal function
Throbocanes
Platelet Aggregation
Tissue damage
COX-2

NSAIDs: What We Do Know - P.11 NSAIDs: What We Do Know - P.11
COX
-Cyclooxygenase – prostaglandin synthase
-Its job is to place oxygen into arachidonic acid
-Metabolizes AA
-It produces mediators of function AND pathology
-Thromboxanes, prostacyclin, prostaglandins E2, F2, D2 -
NSAIDs: What We Do Know - P.12 NSAIDs: What We Do Know - P.12
COX has (at least) 2 isoforms
COX-1 (good?)
-Constitutive
-Platelets
-Kidneys
-Stomach
-Repro tract
-Maintains homeostasis
-Renal blood flow
-Gastric secretion
mucus COX-2 (bad?)
-Inducible
-Fibroblasts
-Endothelial cells
-Chondrocytes
-Macrophages
-Constitutive
-CNS
-Kidneys
-Main inflammation mediator and of pain -
NSAIDs: What We Do Know - P.13 NSAIDs: What We Do Know - P.13
COX-3???
-Simmons D, et. Al. Proc Nat Acad Sci 2002
-“COX-1 variant or isoform expressed in high amounts in brain and heart”
-Acetaminophen
-Poorly inhibits COX-1 and COX-2
-Greatly inhibits COX-3
-Partial COX-1 or PCOX-1 proteins abundant in canine brain -
NSAIDs: What We Do Know - P.14 NSAIDs: What We Do Know - P.14
How did isoforms influence the industry
-If COX-2 is the enzyme that mediates bad things.........
-Suppressing it alone and sparing COX-1 would limit side effects of
-GI ulcers
-Platelet inhibition
-Renal perfusion -
NSAIDs: What We Do Know - P.15 NSAIDs: What We Do Know - P.15
Classes of NSAID
-Nonselective
-Inhibit both COX-1 and COX-2
-Aspirin, flunixin
-Preferential
-Inhibit COX-1 and COX-2, but less COX-1
-Carprofen, meloxicam
-Selective
-Inhibit COX-2 only
-Deracoxib, firocoxib -
NSAIDs: What We Do Know - P.16 NSAIDs: What We Do Know - P.16
Because enzymes don't read books
-COX-2 can be good in some tissues
-Damaged gastric epithelium
-Hypovolemic and developing renal tissues
-Brain
-Endometrium
-Although COX-2 is mainly “bad” it may also modulate (help decrease) inflammation long term -
NSAIDs: What We Do Know - P.17 NSAIDs: What We Do Know - P.17
Ratio problems; COX-2: COX-1
-Selectivity of a particular NSAID for one isoform or the other is expressed as a ratio.
-The higher the ratio, the less SPARING to COX- 1. -
NSAIDs: What We Do Know - P.18 NSAIDs: What We Do Know - P.18
COX-2 to COX-1
-
NSAIDs: What We Do Know - P.19 NSAIDs: What We Do Know - P.19
Great! That solved it.
-
NSAIDs: What We Do Know - P.20 NSAIDs: What We Do Know - P.20
Nope! There is a problem with COX ratios
-Assays were done in vitro, not in vivo
-Recombinant enzymes or whole cell cultures?
-Selectivity for isoform may be lost at greater concentrations (clinical concentration) of drug
-Individual isoform variability
-Length of study
-Species differences -
NSAIDs: What We Do Know - P.21 NSAIDs: What We Do Know - P.21
So things are not as simple as we would like them. Why?
-Genetic expression of isoform differs from individual to individual
-Enzymes which metabolize NSAIDs differ from one individual to another
-At clinically effective doses, some NSAIDs lose their preference for one COX isoform -
NSAIDs: What We Do Know - P.22 NSAIDs: What We Do Know - P.22

Do the Risks Outweigh the Benefits?
- Benefits and risk of any medication is assessed on a case by case basis
- Understanding the different types of adverse events:
- Allows veterinarians to minimize the risk
- Better communicate the actual risks to pet owner
- Appropriate patient selection is key to maximize the benefits of NSAID use
Benefit
Risk
For the Vast Majority of Canine Patients, the Benefits Outweigh the Risks -
NSAIDs: What We Do Know - P.24 NSAIDs: What We Do Know - P.24
Adverse Reactions for All Drugs Fall into Two Major Categories
Inducible Idiosyncratic
Reactions Are Dose-related
Reactions Are Attributable to the Mechanism of Action of the Drug
Predictable
Examples: Antineoplastic Drugs - Neutropenia NSAIDs - GI Signs
Not Dose-related
Not Attributable to the Mechanism of Action of the Drug
Unpredictable and Rare; Maybe Serious
Examples: Penicillins - Anaphylaxis NSAIDs - Hepatic Toxicity -
NSAIDs: What We Do Know - P.25 NSAIDs: What We Do Know - P.25
The Risk of an Adverse Reaction is Greatest Early in Treatment
- The most common seen with NSAIDs are inducible, and include GI irritation
- Typically occur early in treatment
- Idiosyncratic reactions occur infrequently (<1 in 10,000)
- Idiosyncratic reactions are most likely to occur in the first 90 days of treatment
- Although individual response may vary, benefits of NSAID use outweigh the risks or the majority of dogs
Appropriate Patient Selection and Monitoring During Treatment Can Minimize the Potential for Adverse Events

NSAIDs: What We Do Know - P.26 NSAIDs: What We Do Know - P.26
FDA NSAID Class Language on “Lowest Effective Dose”
- The Label Language: Lowest effective dose for the shortest duration consistent with individual response
- Duration of treatment should be determined by the patient’s response
- Start at lowest FDA Label Dose; some NSAIDs have dose range
- If considering a reduction in dose monitor to ensure that the lower dose is effective
- For idiosyncratic reactions, reducing the dose does not decrease the risk
- Addressing other issues? – Obesity, chondroprotection?
- Decision for dose and duration of treatment is based on patient and Benefit/Risk analysis -

So let’s move on to renal adverse effects
- Related to inhibition of COX-1 and COX-2
- COX-2 necessary for renal development
- Basal kidney function doesn’t depend on COX or its prostaglandin production
- But....during hypovolemia or hypotension
- COX-1 maintains blood flow
- COX-2 mediates renin release and tubular function -

My own rules for perioperative NSAIDs
- Avoid NSAIDs in patients with
- Clinical ARF
- Failure vs. chronic disease

Cats and NSAIDs
- Most NSAIDs are metabolized via glucuronidation
- Cats deficient in glucuronyl transferase enzymes
- Toxic metabolites increase rapidly with repeat dosing of certain NSAIDs
- Subclinical renal impairment likely in this species
- Operative monitoring of perfusion is very tough, hence most operative problems common, let alone those with NSAIDs
- Acetaminophen toxicity

Minimizing the Risk: Concurrent Medications
- Concomitant use of NSAIDs with other anti-inflammatory drugs such as corticosteroids and other NSAIDs should be avoided
- Pet owners may not disclose that they are treating dogs with aspirin
- 7% veterinarians recommend aspirin to treat canine osteoarthritis7
- 28% of pet owner indicated that they use aspirin to treat their dogs osteoarthritis7
- Studies to determine the activity of NSAIDs when administered concomitantly with other protein-bound or similarly metabolized drugs have not been conducted
- Drug compatibility should be monitored closely in patients requiring cardiac, anticonvulsant and behavioral medications1. Deramaxx Package insert, NADA # 141-203, 2008 Novartis Animal Health.

NSAIDs: What We Do Know - P.57 NSAIDs: What We Do Know - P.57
Minimizing the Risk: Pet Owner Communication
- Always provide a Client Information Sheet with prescription
- Pet owners should be:
- Informed regarding potential adverse events
- Advised to discontinue NSAID therapy if side effects occur and contact their veterinarian
- Store palatable formulations out of reach of dogs, in a secured location. Severe adverse reactions may occur if large quantities of tablets are ingested
- Made aware of the importance of periodic follow-up for
- Safety, Efficacy, Compliance
- Development of unrelated conditions -
NSAIDs: What We Do Know - P.58 NSAIDs: What We Do Know - P.58
Not recommended when
- Hyperbilirubinemia
- Elevated ALT, AST and GGT
- If any of these are elevated alone or in combination, with or with out signs of hepatic disease
- Albumin decreased – Recommend workup for renal, GI or hepatic dysfunction
- Clotting disorder
- Elevated ALP with clinical signs of liver or Cushing’s disease -
NSAIDs: What We Do Know - P.59 NSAIDs: What We Do Know - P.59
ALP is elevated, but normal dog
- Could be Benign Nodular Hyperplasia
- Is fairly common in older dogs
- ALP can be 2.5x to >10x normal
- Ultrasound and Bile Acids to rule out other disease
- Additional diagnostic as needed
- Consider NSAIDs if no other underlying disease detected
- Monitor to ensure no further elevation or other abnormalities (within 10–30 days, then periodically)
- Any further increases in hepatic enzymes warrants further evaluations -
NSAIDs: What We Do Know - P.60 NSAIDs: What We Do Know - P.60
My NSAID Rules
- Use one or two in your clinic. Be comfortable with them.
- Don’t mix NSAID & NSAID. Don’t mix steroid & NSAID.
- It’s not working. Can it handle it alone? Do we need a helper? (gabapentin, amantadine)
- Client handouts, emails and “if vomiting, diarrhea, dark tarry stools STOP med and CALL OFFICE” on EVERY LABEL. -
NSAIDs: What We Do Know - P.61 NSAIDs: What We Do Know - P.61
More rules
- Use manufacturers dosing. Tapering to “least effective” could bring back windup, and we under diagnose pain already...
- If I have to change NSAID (or to/from pred): washout (5-7 days) bridge (Gabapentin, buprenorphine, Tylenol)
- I stick with brand names. – Product support, reliability.
- Break a tablet in half – is it equally distributed?
- Have a problem? Report it -
NSAIDs: What We Do Know - P.62 NSAIDs: What We Do Know - P.62
What is GALLIPRANT® (grapiprant tablets)?
- Galliprant is a first-in-class non-cyclooxygenase (COX) inhibiting, non-steroidal anti-inflammatory drug (NSAID) in the piprant class.
- Piprants are a newly recognized drug class, established and defined by the World Health Organization in 2013 as prostaglandin receptor antagonists (PRA).
- Unique mechanism of action by antagonizing the prostaglandin E2 (PGE2) EP4 receptor.
- PGE2 its physiologic effects through binding of four different receptors, EP1, EP2, EP3, and EP4.
- EP4 receptor has been identified as the primary receptor responsible for mediating pain and inflammation associated with osteoarthritis. GALLIPRANT selectively blocks the EP4 receptor, thus blocking PGE2 elicited pain. -

Key Points to Consider When Choosing an NSAID
- NSAIDs in general are safe and efficacious
- Start treatment using preferred NSAID
- Monitor pet owner – efficacy, compliance safety and - With and outweigh monitoring, appropriate the risk benefits patient for most will selection dogs
- Consider consequences of not treating
Benefit
Risk
- Change in NSAID maybe required based on patient’s response
- One drug maybe more effective than another drug
- One drug may be better tolerated
- Pharmacogenetics may play a role in the variability -

Non-shockable Rhythms
VF/Pulseless VT
Asystole/PEA
-Continue BLS, charge defibrillator
-Clear and give 1 shock or Precordial Thump if no defibrillator
-With prolonged VF/VT, consider
-Amiodarone or Lidocaine
-Epinephrine / Vasopressin every other cycle
-Increase defibrillator dose by 50%
-Low dose Epinephrine and/or Vasopressin every other BLS cycle
-Consider Atropine every other BLS cycle
-With prolonged CPA > 10 min,consider
-High dose Epinephrine

Evidence-based CPR: The Recover Guidelines - P.51 Evidence-based CPR: The Recover Guidelines - P.51
Non-shockable Rhythm
- Asystole (most common)
- Continue compressions
- Pulseless Electrical Activity
- Pulseless, <200 bpm
- Continue compressions
- Drugs -
Evidence-based CPR: The Recover Guidelines - P.52 Evidence-based CPR: The Recover Guidelines - P.52
CPR Drugs
- Epinephrine
- Arterial Vasoconstrictor
- Increased aortic pressure -> Increased CPP
- Low Dose: 0.01mg/kg
- High Dose: 0.1mg/kg
- Vasopressin (0.4-0.8 U/kg)
- Smooth muscle vasoconstrictor
- Alternative to Epinephrine
- Half life longer (10-20 min)
- Atropine(0.05mg/kg)
- Blocks vagus nerve(Parasympathetic)
- Increases HR
- 0.05mg/kg or 1ml/10 lb

"I feel like things are so organized. We have very smooth CPR attempts."
"I can’t remember how we used to do this before the new protocol. It feels so calm going through the compression cycles. "
"We still have our chaotic sessions, but I like how everyone knows what should be happening. The debriefing helps a lot."
"With the new protocol, we are doing the best job possible. Our patients get the best chance." -
