Pierce, DVM, DACVIM Kim Gugler, DVM V Room B ROOM A Use of Patient Signalment in the Diagnosis of Neurologic Disease Brian Cellio DVM ACVIM (Neurology) Felines • Ischemic Myelopathy (mean age 14 years) – Clinical Signs: • Acute, non-painful, and non-progressive cervical lesion resulting in various degrees of tetraparesis or tetraplegia. • Cervical ventroflexion – Diagnosis: • MRI – Treatment: • Supportive – Prognosis: • Favorable Yorkshire Terrier • Portosystemic Shunt • Atlantoaxial Instability • Necrotizing Leukoencephalitis • Portosystemic shunt (< 1 year of age) – Clinical signs: • Reflective of forebrain disease • Altered mentation, pacing, visual deficits and seizures – Diagnosis: • Transcolonic portal scintigraphy – Prognosis: • Fair to good • Atlantoaxial Instability (<2 years of age) – Clinical signs: • range from mild cervical pain to tetraplegia – Diagnosis: • Non-sedated, mildly ventroflexed lateral radiograph – Treatment: • Surgical • Conservative – Prognosis • • Fair Necrotizing Leukoencephalitis (1-10 years of age) – Young, adult females over-represented – Clinical Signs: • Seizures are the most common clinical abnormality but signs represent the distribution of brain lesions – Diagnosis: • Spinal tap with CSF analysis • Advanced imaging – Treatment: • Immunosuppression – Prognosis: • Grave Boxer • Degenerative Myelopathy • Idiopathic Head Tremors • Aseptic Meningitis • Boxer • Degenerative Myelopathy (≥ 8 years of age) – Clinical signs: • An insidious onset of a non painful deterioration in rear limb function resulting in progressive paresis and ataxia – Diagnosis: • Genetic testing – Treatment: • None – Prognosis • Poor • Idiopathic Head Tremors (adult onset) – Clinical Signs: • A series of repetitive involuntary muscle contractions involving the head and neck occurring in either a vertical or horizontal direction – Diagnosis: • Clinical presentation – Treatment: • None needed – Prognosis: • Excellent • Aseptic Meningitis (< 2 years of age) – Clinical Signs: • Arched back with cervical ventroflexion (pain) • Stiff, stilted gait – Diagnostics • Spinal tap with CSF analysis – Treatment: • Immunosuppression – Prognosis: • Good to excellent Pug • Type II Intervertebral Disc Disease • Spinal Arachnoid Cyst • Type II Intervertebral Disc Disease (older) – Clinical Signs: • Insidious onset of a non painful, slowly progressive ataxia and paresis of the rear limbs – Diagnosis: • MRI – Treatment: • Conservative • Surgical (rare) – Prognosis • Fair • Spinal Arachnoid Cyst (adult age) – Clinical signs: • Insidious onset of a non painful, slowly progressive ataxia and paresis of the rear limbs • Urinary and/or fecal incontinence – Diagnosis: • MRI – Treatment: • Conservative • Surgical (preferred) – Prognosis: • Good with surgery • Secretory Otitis • Syringomyelia • Secretory Otitis (adult onset) – Clinical Signs: • Moderate to sever pain, vestibular and/or facial nerve dysfunction, and hearing loss – Diagnosis: • Otoscopic exam • Bullae radiographs • Advanced imaging – Treatment: • Ventral bulla osteotomy • Myringotomy – Prognosis: • Excellent Cavalier King Charles Spaniel • Syringomyelia

lameness • Ipsilateral miotic pupil possible – Diagnosis: • MRI – Treatment: • Amputation – Prognosis: • Variable End Rational Use of Antacids Crystal Hoh, DVM, MS, DACVIM Overland Park, KS Topics to Cover • Adverse Effects of Antacids • Indications for Use • Proactive Esophageal Reflux Therapy • Steroid Induced Ulcers • Brief Reminder of Drug Mechanism of Action • Specific Drugs Used • Questions Adverse Effects Dogs / Cats • Drug absorption issues • Cytochrome P450 interference • Rarely diarrhea or vomiting • Shifts in flora – uncertain consequences • Likely rebound hyperacidity with chronic use • One extra medication, lower compliance Adverse Effects Humans (PPI) • Low magnesium causes low calcium • Muscle tremors / twitching / weakness • Bone fracture • Increased risk for bacterial gastroenteritis • Increased risk C difficile • Chronic use ~1-5 years or more Adverse Effects Rodent Studies (PPI) • Gastric hyperplasia with increased gastric carcinoma risk Essential Antacid Use • Esophagitis • Esophageal stricture • Esophageal foreign body • Known causes for gastroesophageal reflux • Severe GI bleeding (suspected ulcer) – Melena – Hematemesis – Low MCV anemia Signs of Esophagitis – Ptyalism – Neck stretching – Dysphagia – Hard swallow – Cough – Snorting (nasopharyngeal stricture) – Regurgitation – Moaning / Discomfort – Inappetence Good Idea Antacid Use • Abdominal surgeries (rate of reflux up to ~38%-50% in longer procedures as measured by probe monitoring) • Prolonged fasting / inappetence • Vomiting / regurgitation • Acute Renal / Liver disease • Pancreatitis May Help, Lower Priority • Chronic renal disease • Chronic liver disease • Prolonged inappetence • Chronic gastrointestinal disease Proactive Esophageal Reflux Therapy • • Surgical reflux – Up to 50% of dogs will have reflux under anesthesia – Worse abdominal procedures – Antacid with metoclopramide or cisapride – At least 50% of esophageal strictures are caused by surgical reflux Esophagitis can cause regurgitation / loss of appetite / prolonged recovery and hospitalization Sodium Bicarbonate – Reflux Therapy • Suction to remove reflux but not enough • Lavage warm water until fluid looks clear • Instill sodium bicarbonate 4.2% solution ~20 mls • Need well inflated tracheal tube cuff, be certain not in trachea! • 12 Fr catheter Steroids and Ulcers • Dexamethasone used in models to cause ulcers • 75% of IVDD dogs develop ulcers • None of these can prevent steroid ulcers – Omeprazole – Misoprostol – Sucralfate – Cimetidine Steroid Ulcer Healing • Natural healing no treatment 12-14 days – Treatments tried • Lansoprazole (PPI) • Sucralfate • Misoprostol • Famotidine • Seabuckthorn seed oil Steroid Ulcer Healing • • Dogs 15-25kg – Seabuckthorn seed oil 5 mL/dog, q12h – Healed the fastest (day 6) Famotidine 1 mg/kg q12h – next fastest (day 7.5) Human Ulcer Healing Guidelines • Duodenal and esophageal pH > 4 for 75% of day • pH values > 4 inactivate pepsin and inhibit fibrinolysis • Gastric bleeding: hemostasis – pH > 6 needed – At least 66% of day to heal Proton pump Stomach Acid Production H2 Acetylcholin e Gastrin Famotidine – Pepcid AC • H2 receptor antagonist • Can increase pH > 4 for up to 48% of the day • 1 mg/kg, q12h dosing • Gastrin levels returned to baseline by day 14 of treatment – May become less effective with chronic use – Rare anecdotal hemolysis cats rapid IV (not proven in study) Ranitidine - Zantac • H2 receptor antagonist • Prokinetic properties • Multiple studies have shown no pH changes over placebo • Gastrointestinal emptying time not changed compared to placebo • False positive urine protein on Multistix • Probably not a good choice in dogs or cats Cimetidine - Tagamet • H2 receptor antagonist • Weak inhibitor of cytochrome P450 enzymes • Anti-androgenic effects • Cannot be substituted for ketoconazole to increase cyclosporine levels • No change in esophageal pH during reflux in OHE dogs • Dosing needed q6-8h • Likely not good choice in dogs Omeprazole – Prilosec OTC, Gastroguard • Proton pump inhibitor (PPI) • Inhibits cytochrome P450 enzymes • 1 mg/kg PO q24h for most conditions is fine • Need q12h for severe bleeding ulcers (75% of day pH over 4-6) • Cut tablets still effective in cats Sucralfate - Carafate • Gastroprotective drug • Needs low pH to form paste and bind ulcers • ¼-1 gram per animal PO or in slurry q8h • Interfere with other medications. • Separate from other drugs / food by 2 hours • Best given q8h • Anecdotally soothing properties for rapid relief END Veterinary Technicians The Next Profit Center CHRIS.MORROW@MCCKC.EDU What is profit? Profit = Business Success, Job Security, Happiness Profit = Revenue – (Operating Expenses + Overhead) Remember when you made a good profit from… Vaccines Dewormers Flea and Tick Products Drugs Food Spays/Neuters Lab Tests Veterinary Economic 2011 Benchmarks: Expense type Percentage of total practice revenue 2007 2009 2011 Variable 21.8% 24.5% 25.1% Fixed 9.0% 8.9% 8.9% Staff 25.6% 25.3% 24.7% Facility 8.0% 8.4% 8.8% Reinvestment 5.9% 4.3% 4.5% Revenue has increased, but operating expenses have increased more! 2007 AVMA Study: Table 1—Results of an ordinary least squares regression model to evaluate the effects of staffing on gross revenue in private veterinary practices in the United States, 2007. Variable Gross revenue ($) No. of full-time Equivalent veterinarians = 1.73 Full-time– Equivalent veterinarians 318,545 Credentialed Veterinary technicians to veterinarians 161,493 Noncredentialed Veterinary technicians to veterinarians 10,567 Veterinary Technician Utilization 2007 AVMA Study found: $93,311 increased gross revenue per Credentialed Veterinary Technician added What is a Technician? Missouri Veterinary Board Definitions "Registered veterinary technician", a person who is formally trained for the specific purpose of assisting a licensed veterinarian with technical services under the appropriate level of supervision as is consistent with the particular delegated animal health care task "Unregistered assistant", any individual who is not a registered veterinary technician or licensed veterinarian and is employed by a licensed veterinarian Dr. Morrow’s Definition: A Veterinary Technician has… a license. medical knowledge to pass the National Exam. legal knowledge to pass the State Exam. I want someone who has something to lose because my license is on the line! LICENSE = TECHNICIAN NO LICENSE = ASSISTANT Any Technician, RVT Even when they have a license they still have to … EARN MY TRUST! I would not hire a new Veterinarian and immediately go on vacation. Why would I expect to do the same with my new RVT? Step 1 UTILIZE THE TECHNICIANS ENTRY LEVEL SKILLS Utilize their client communication skills! 30 minute examination time – 10 minutes: Obtain History Establish Visit Plan Obtain Client Authorization Sample Collection 10 minutes: Veterinary Exam / Consult 10 minutes: Client education on treatment, monitoring, recheck scheduling Create Technician Appointments All of us want to market our hospitals. Give them their own business cards. Let them bond with the clients! Common Error = Clients only bonded with Veterinarian If clients are only bonded with you, then taking a day off or selling your practice in the future will be harder. Schedule Technician Appointments Create A Separate Technician Schedule If you do not have enough room, then take a longer lunch time! I currently get a 3 hour lunch from 12:00 - 3:00 PM. It works great!

Fecal Exam: Float, Centrifugation, Cytology Urine Exam: Urinalysis and Culture Blood Smears: Hemoparasite identification, WBC estimates, RBC estimates, Platelet Estimates Skin Scrapes Ear Cytology Fungal cultures Technician Appointments Increased Production Happier Employees Happier Clients Increased Bonding of Clients to Practice Increased Revenue 2011 DVM360 article by Karen Felsted, CPA, MS, DVM, CVPM Step 2 SUPPORT THEM IN BRINGING NEW SERVICES TO YOUR PRACTICE Allow Technicians to grow and improve! Most common reason that Veterinary Technicians leave a hospital……they are under utilized and they feel burned out. They want to help animals and to be a productive member of the veterinary team. Like us, they get energized by learning something new and using their new skills.

My Daily Approach Susan Keil, DVM, DACVO Basic “Rules” History Signalment Ocular Exam Treatment / Plan Types of Canine Ulcers Types of Feline Ulcers Patients are too stoic: ulcers hurt! Patients do rub Don’t listen to the client, listen to the patient – Owner will blame cat, groomer, in-law’s dog and tell you it just started – Patient will show you the story Basic “Rules”: 3 Canine Ulcers All types are painful Simple: heal 1-3 days on their own, any age Refractory/indolent/Boxer/SCCED: middle/older age, chronic, superficial, not infected Complicated: infected and/or deep any age, can be superficial hypopyon, steamy cornea, bugeyed patients Basic “Rules”: One Feline Ulcer VIRAL / HERPES – Ulcerative* – Sequestrum – Stromal – Eosinophilic Keratitis Complicated Basic “Rules”: Ulcers Hurt Tramadol – 2 to 4 mg/kg BID-TID Oral NSAID – Rimadyl 2.2 mg/kg BID; 4.4 mg/kg QD – Deramaxx 1-2 mg/kg QD Feline – 81 mg aspirin q 2-3 days Basic Rules: The Stupid Cone Use appropriate sized / fitted collar – some have to be cut back; - warn about doggie door Some collars do not work: donuts, neck brace Generates justified revenue Helps keep out of pond, garden, woods (hope) Rubbing is bad – delays healing, increases rate of rupture, infection Write in record when client declines Comfy-cone (has rigid inserts): Amazon $27 Basic “Rules” Diagnosis the ulcer type to help you determine your treatment plan If improvement is not appropriate, recommend referral History Take a thorough, filtered history Trauma: cat claw = puppies, grass seeds = hunting/hiking, blunt/sharp objects Acidic/alkalotic: shampoos, cleaning agents Acute: trauma, chemicals, melting (infected) Recurring: dry eye, aberrant hair, entropion Chronic: refractory Young (< 5 yrs) dogs do not get refractory ulcers Signalment o Boxer: refractory Puppy: entropion, ectopic cilia, cat claw Bug-eyed: exposure, dry eye, nasal trichiasis, chronic micro-traumas Breed related: Yorkie/Pug=congenital dry eye, Shar Pei/Chow/Bulldog=entropion, Shih Tzu/Boston/Lhasa/Bulldog=stromal keratitis, Bulldog/Cocker/Westie/Frenchie=dry eye Ocular Exam Menace: – assess function o helps guide tx plan Dazzle/PLR – assess function, severity Schirmer Tear Test – VERY important – check other eye: clues! – repeat after healed – maybe falsely elevated Ocular Exam Fluorescein Stain nontoxic, excites at 480 nm (blue) – detects ulcers, extremely hydrophilic epithelium very hydrophobic dendritic ulcers need blue light to enhance binds to exposed stroma; flush well tear small piece of strip, put in 3 cc syringe & fill with saline for a few days (then toss!) IOP: tonovet, tonopen – use caution on soft, infected corneas – change tip / cover if suspect infected – evaluating reflex keratouveitis Use topical anesthesia Cytology: dull blade end – Kimura spatula – collect from ulcer edge – use caution Culture – microtip culturette – collect from within ulcer – use caution Administering Topical Meds Wait 5-10 minutes between medications – allow first drug to absorb Thinner before thicker (ointments last) – doesn’t matter which drop goes first – specify to client if need drops at different times to maximize therapy (multiple antibiotics) Delivery volume of one drop 35-50 microliters – lacrimal lake holds 30 microliters – one drop is all you need per treatment Feline Ulcer: Diagnosis Important: diagnosis of FHV-1 based on the history/signalment/exam, confirming this is not a complicated ulcer – stresses: neuter/OHE, moved, baby, fiancé o older cat – think underlying disease; do general exam and recommend CBC/Profile/FeLV/FIV/Toxo (note if decline) – often will not see classic dendritic ulcers, but will get stain uptake: STILL THINK HERPES – I do not do cytology/culture and rarely do viral testing – Suspect 90-95% of all cats have FHV-1 Feline Ulcer Diagnosis Epiphora, chemosis, blepharospasm, stain positive, +/- dendritic ulcers, blood vessels No additional tests Do you elect to treat? – mild, may elect to run course – may not start antiviral o pilling, topical frequency Feline Ulcer: Treatment No Elizabethan collar Antiviral!!! – Oral Famvir: 125 – 250 mg QD – BID for days, weeks, month(s) – Topical Idoxuridine: 1 gtt 6 times daily x 2 days, then QID for days/wks, then taper Atropine OINTMENT – QD-BID, tapering Terramycin / Erythromycin ointment: – ¼ inch strip (bead) TID x 3 weeks o prophylaxis, unlikely bacterial infection Lubricant: soothing (Genteal, Refresh, Optix) Recheck: depends on severity / discomfort – one week average, then may require more Daily lysine if patient will take (don’t stress) – Equine VitaFlex (pure lysine) from Farnam (4 pounds) o Fill 40 dram vial 80% full; dispenser - clear end of monoject 20 gauge needle Don’t forget the antiviral Feline Ulcer: Recheck 7-10 days Have client call if worse / not improving Refer: sequestrum, stromal keratitis, eosinophilic keratitis, not improved by recheck, getting worse Canine Simple Ulcer Hx / Diagnosis – sudden – any signalment – positive stain o superficial o not infected o not chronic problems – epiphora – +/- miosis – mild to severe pain Treatment – broad spectrum topical antibiotic TID x 5 days o triple antibiotic – oral NSAID 1-4 days – lubricant o OTC (Genteal, Refresh) – atropine solution o one in-house dose? o QD / BID x 1-3 days – tramadol Canine Simple Ulcer Should heal no matter what we do or don’t do in 1-3 days No(?) Elizabethan collar Recommend recheck in 2-5 days if not 100% or gets worse at any point Canine Refractory Ulcer Hx/Diagnosis – chronic (1-3+ weeks) – middle / older age – Boxer (but any breed) – undermining + stain o superficial o not infected – mild to severe pain – +/- miosis – zero to extreme neovascularization Refractory Ulcer Treatment Once diagnosed, needs a diamond burr (grid) keratectomy (80% heal rate) Changing antibiotics will not increase healing Do not perform keratectomies on infected ulcers or descemetoceles! Get into an Elizabethan collar 50% of patients will develop same ulcer in opposite eye within 18 months Refractory Ulcer Treatment Mydriatic – reflex keratouveitis – atropine solution BID x 4 days, then QD UR Prophy antibiotic – tobramycin TID UR Oral NSAID UR Lubricant (Optix, Genteal, Refresh) Tramadol Don’t need serum Refractory Ulcer Tx/Recheck Contact lens – 80% retention – increases to 95% healing – do not put on infection – really want E-collar on Recheck 2-3 weeks – if not healed, repeat procedure if painful – if open/comfortable, give more time Canine Refractory Ulcer This ulcer is caused by an epithelial basement membrane (collagen IV) defect – need to stimulate BM – have seen ulcers 6 – 12 months chronic (18 mo*) – painful; changes personality Do not perform a grid keratectomy on cats – will generate sequestrum formation – soft diamond burr may work to debride Canine Refractory Ulcer I do not perform cytology / culture on refractory If you don’t know it is refractory, cytology should be helpful in confirming not infected Canine Complicated Ulcer Infected (any depth) Descemetocele Bug-eyed patients higher risk Apply topical anesthetic – help relax – sedate if necessary Does the eye work??? Once diagnosed, recommend referral Complicated Ulcer Hx/Diagnosis Acute, subacute, chronic Brachycephalics, chronic ocular dz higher risk Any age Superficial, mid-stromal, deep stromal stain Descemetocele center stain negative Moderate to extreme pain ADR, anorexia, crying Miosis, hypopyon, edema/steamy cornea Zero to significant neovascularization Complicated Ulcer Diagnosis Look at opposite eye – KCS Look for aberrant hairs – nasal trichiasis Can the patient blink? Corneal cytology – use caution, may rupture Corneal culture Complicated Ulcer Treatment Elizabethan collar!! No ointments Tramadol: pain control, keeps them quiet Oral NSAID – Rimadyl Atropine solution:1 gtt BID – QID Refer – medical – surgical Complicated Ulcer Treatment Ofloxacin (or other enrofloxacins) – 1 gtt 5x daily on odd hours x 2 days, then 4x daily x 3-4 days, then TID for 7-10 days Cefazolin in Artificial Tears (expires in 10 days) – 3 mls diluent into 1 gram cefazolin – pull 1 ml from 15 ml AT bottle – See ofloxacin (given on even hours) x 10 days Dilute Betadine solution (1:10): 0.5 mls TID Serum: 0.2 mls QID until stable Complicated Ulcer Recheck 24 hours after start therapy – is pupil dilating? – is eye more relaxed? – does cornea stabilizing (less keratomalacia) – to much structural loss? Continue with medical therapy? Is corneal/conjunctival surgery required? Rechecks then 2 days, 4 days, one week Canine Complicated Ulcer No ointments – difficult application – do not want petrolatum inside eye Leave caked debris/nasal trim for later – trim direct contact If struggling, drops If ruptured, just atropine Do NOT grid! Office Hours Monday, Tuesday, Thursday 7:30 – 5:00 Wednesday 7:30 – 5:45 Friday 8:00 – noon Emergency services 24/7 END Does this fracture need surgery? Fracture assessment, Initial stabilization, and decision making Ralph P.

Open Fractures • Unique combination of orthopedic and soft tissue injury – Infection – Delayed Union – Non-Union Wound Management • • • • • • • • • • Confirm patient stable Classify wound Copious K-Y (sterile) Clip wide Clean surrounding skin Copious wound lavage Cut (debride necrotic tissue) +/- Culture Cover (bandage) wounds Rigid external support Open Fracture Classification (Gustilo-Anderson, Types 1-3) Type I: An open fracture with a wound smaller than 1 cm – Surrounding soft tissues are mildly/moderately contused. Frequently the external wound is created from the inside out by sharp bone fragments • Type II: An open fracture with a wound larger than 1 cm without extensive soft tissue damage, flaps, or avulsions – The external wound typically is created from the outside in by high energy forces Type III: An open fracture with extensive soft tissue damage. Soft tissue avulsion, de-gloving injury, and bone loss are frequently noted. These include fractures with accompanying neurovascular injury requiring repair, gunshot injuries, and traumatic partial amputations IIIA: Adequate soft tissue coverage despite extensive soft tissue laceration or flaps IIIB: Extensive soft tissue loss, periosteal stripping and bone exposure IIIC: Associated arterial injury requiring repair • Open Fractures: ANTIBIOTICS Required component of successful outcome Timing: < 3 hours after injury sig lower infection rate compared to 4 hours or greater Coverage – Type I or II: First generation cephalosporin – Type III: Broader coverage, cephalosporin & fluoroquinolone – Nosocomial Infections (82%) – Open Fracture Treatment • • • • • • Bone plates, plate rod, interlocking nail and external skeletal fixators Type I fractures often treated similar to closed Type III/severely contaminated – External skeletal fixator **External coaptation NOT recommended for definitive stabilization. Open Fracture Outcomes • Infection rates – Type I: 0-2% – Type II: 2-10% – Type III: 10-50% Delayed union/non-union – Type I: 0-5% – Type II: 1-14% – Type III: 2-37% Temporary Fracture Stabilization • • • Reduce further injury: – Soft tissue (neurovascular) – Musculoskeletal Attenuate painful stimulus Prevention of open fracture Bandage Anatomy • • • Primary Layer (if wound) – Adherent – Non-adherent Secondary Layer (absorb and support) – Cast Padding – Kling Tertiary Layer (support and protect) – VetWrap Temporary Fracture Stabilization • • • • Humerus – Spica or nothing Radius/Ulna (or distal) – Modified Robert Jones Femur – Spica or nothing Tibia/Fibula (or distal) – Modified Robert Jones Bandage Complications • • • • • • • • • Moist dermatitis Skin necrosis / Gangrene Valgus deformity of the forelimb Amputation of limb or digits Death Closely monitor bandages and digits – Swelling, warmth, odor, moisture 63% developed soft-tissue injury – 60% mild, 20% moderate, 20% severe Can occur at any time frame, no association with duration of cast/splint Cost of treatment 4-121% cost of original ortho procedure Fracture Decision Making • • • • Biomechanics fracture repair Cost Patient Dynamics Owner Dynamics Definitive Stabilization Decision-Making Compression Tension Bending Rotation Shear Traumatic Fractures • • • • • • Activity restriction Closed Reduction External Coaptation (Splint/Cast) ORIF (Open reduction and internal fixation) Closed/Open reduction and rigid external fixation (external skeletal fixator) Closed reduction internal fixation (ILN, Flouro guided) MIPO (Minimally Invasive Plate Osteosynthesis) Definitive Stabilization (External Coaptation) • • • • • Distal to elbow/stifle Incomplete fractures Simple minimal/non-displaced Young* Financial constraints – Cost of bandage changes or complications External Coaptation • • Toy breed Distal radius/ulna fracture Metacarpal/tarsal Fractures • • • • • • More than two metacarpal/tarsal fractures present Involves both III and IV Articular Displaced by > 50% Involve base of II or V (collaterals) Large breed or athletic/working Sacroiliac Luxation • Indications for internal fixation – Pain – Instability/inability to bear weight – Compromised pelvic canal or joint alignment – Contralateral injuries requiring internal fixation Scapular Fractures • • Unstable extra-articular (neck) fractures and articular fractures are optimally managed with internal fixation. Scapular body fractures – Minimal displacement – Can have inherent stability – Can heal rapidly Summary • • • Most traumatic fractures require (at least have indication) surgical stabilization Temporary stabilization is ALWAYS indicated for fractures distal to elbow and stifle. Coaptation (definitive) – Distal to elbow or stifle – Sufficiently stable in coaptation – Expected to heal quickly (incomplete or minimamaly displaced, young etc) Thank You END Treating Diabetic Ketoacidosis Heather Gill-Bragg, DVM Small Animal Internal Medicine, Resident Insulin Deficiency: Absolute and Relative Insulin made & secreted by pancreatic β cells. Deficiency leads to: – Decreased tissue utilization of glucose, aa, FA – Accelerated hepatic glycogenolysis and glucogenesis – Accumulation of glucose in circulation Absolute: no insulin produced Relative: inability of insulin to work appropriately – Main sites: liver, muscle, adipose tissue Formation of Ketone Bodies Most impt regulators of ketone body production are: – FFA availability – Ketogenic capacity of the liver FFA are oxidized by liver and used as energy source when glucose deficiency (real or perceived) is present FFA turned into ketone bodies: – Acetoacetate – β-hydroxybutyrate – Acetone Treatment of “Healthy” DKA Regular insulin (0.1-0.2U/kg/injection) SQ TID until ketonuria and ketonemia resolves (4896hrs) – Feed 1/3 daily caloric intake at time of each injection – Adjust based on clinical response and BG measurements - OR Institute intermediate or long-acting insulin and monitor Treatment of “Healthy” DKA If patient remains ketotic, concurrent illness at play Institute more aggressive insulin therapy Treatment of “Sick” DKA 5 GOALS: – Restore H2O and electrolyte losses – Provide adequate amounts of insulin o Suppress lipolysis, ketogenesis, hepatic gluconeogenesis Provide dextrose to allow continued insulin use without hypoglycemia Correct acidosis Identify precipitating factors Our goal is NOT to correct abnormalities as fast as possible due to potentially fatal side effects Correction over 24-48 hours is much more likely to be successful Goal #1: Restore Water and Electrolyte Losses Restore Water Losses Fluids, fluids, and did I mention Fluids? 1 Line of Therapy – (Insulin is NOT the 1 line!)

Insulin Therapy 3 Major Techniques CRI Hourly IM Intermittent SQ/IM Remember….Initiate Fluid Therapy First!!!! (Usually 2-4 hours of fluid therapy prior to insulin) CRI of Regular Insulin Goals: – SLOWLY decrease BG by ~50mg/dL/hr Pros: – Can administer insulin continuously even as BG decreases Cons: – Hourly BG checks – 2 separate lines required: o Insulin CRI pump o Crystalloid fluids CRI of Regular Insulin Regular insulin added to 250ml bag of 0.9% NaCl – Dog: 2.2U/kg – Cat: 1.1U/kg If Glucose (mg/dl) is: Fluids Rate of Insulin CRI (ml/hr) >250 0.9% NaCl 10 201-250 0.9%NaCl + 2.5% dextrose 7 150-200 0.9% NaCl + 2.5% dextrose 5 100-149 0.9% NaCl + 5% dextrose 5 <100 0.9% NaCl + 5% dextrose STOP CRI of Regular Insulin st Discard 1 50ml thru CRI line as insulin binds to plastic! Treatment options moving forward: – Continue CRI until patient is eating/drinking and switch to intermediate/long-acting insulin and discharge – Once BG reaches 250mg/dL -> change to intermittent IM/SQ regular insulin protocol Hourly IM Technique Goals: – SLOWLY decrease BG by ~50mg/dL/hr Pros: – Only need one IV line Cons: – Hourly BG checks Hourly IM Technique Regular insulin in dogs and cats 0.1-0.2U/kg loading dose IM 0.1U/kg IM every 1-2 hours thereafter until BG is appx 250mg/dL Once BG ~ 250mg/dL, then give: – Regular insulin q4-6hrs IM - or – Regular insulin q6-8hrs SQ (only if hydration is adequate!) Maintain BG between 150-300mg/dL – If BG <250, add dextrose to fluids to maintain BG between 150-300mg/dL Intermittent IM/SQ Technique Goals: – SLOWLY decrease BG by ~50mg/dL/hr – Maintain BG between 150-300mg/dL o If BG <250, add dextrose to fluids to maintain BG between 150-300mg/dL Pro: Less labor-intensive Con: Decrease in BG can be rapid, risk of hypoglycemia greater Intermittent IM/SQ Technique Regular insulin 0.25U/kg IM with subsequent IM injections q4hrs Once rehydrated, administer regular insulin SQ every 6-8hrs Insulin dosing (IM and SQ) is adjusted according to hourly BG Goal #3: Provide Dextrose as Necessary to Allow Continued Insulin Use Without Hypoglycemia Goal #4: Correct Acidosis FLUIDS Bicarbonate therapy – [HCO3] <11mEq/L – Dose: o mEq HCO3 = BWkg x 0.2 x (12 – patient [HCO3]) o Administer as CRI over 6 hours. Recheck HCO3 – Complications: o Exacerbation of hypokalemia o Tissue anoxia o Decrease in CSF pH w/ worsening of CSF function o Alkalosis Goal #5: Identify Precipitating Factors ID Precipitating Factors Don’t forget to manage your concurrent illnesses: Pancreatitis Infection Heart disease Renal disease Hepatobiliary disease Endocrine (HAC, hyperthyroidism, diestrus) Prognosis Concurrent illness & client financial constraints often affect outcome more than the metabolic complications of ketoacidosis (Claus et al, 2010) Survival of Dogs (hospitalized) 71% (Macintire, 1993) 80% (Hume, et al, 2006) Survival of Cats 74% (Bruskiewicz et al, 1997) 100% (Marshal et al, 2013) 93% (Claus et al, 2010) 83% (Koenig et al, 2004) 82% (Kley et al, 2002) 69% (Buob et al, 2010) Take Home Points Fluid Therapy is the first line of treatment You need insulin to reverse ketotic state If hypoglycemic, add dextrose to fluids and continue insulin Monitor, Monitor, Monitor References th Canine & Feline Endocrinology, 4 Ed.
