Patient AssessmentTo handle or not to handle…

…that is the question!

Ooops!!

Contraindications To HandlingExtreme dyspnoea

Prostration

Unresponsive to stimuli

Beware of Small Patients

Stop a Clinical Examination when..Bird closes its eyes in your handSudden weaknessFailure to grasp with both feetNo pressure when item inserted in beakImmediately place into heated hospital cage

+/- oxygenObtain a thorough history

Hospitalisation FacilitiesHeat 28-32 degrees CHumidityOxygenNebulisationQuietSubdued LightAvailable food

Fluid TherapyIntravenous

Jugular (right)UlnarMedial tarsal

SubcutaneousInguinal ( bilaterally)interscapular

IntraosseousUlnatibiotarsus

OralCrop gavage

Calculating Fluid RequirementsDaily maintenance: 5% BW/dayPlus % dehydrationAim to replace 50% deficit first 24 hrs

In acute fluid loss, 20-25% of deficit is replaced in first 4-6 hrs.

Then the other 50% over next 24-48 hrs

Fluid VolumesIV fluid Rates

Crystalloids: bolus 10 ml/kg or 10-25ml/kg over several mins

Colloids: 3-5 ml/kgTransient bradycardiaDecompensatory phase of shock (bradycardia,

hypotension, hypothermia) Slow IV/IO bolus over 10 mins of 7.5% hypertonic saline (3ml/kg)

+ colloids (3ml/g)Fluid overload:

Increased RR Cardiac dysrhythmia Agitation Collapse

Subcutaneous Fluid Volumes5-10% bodyweight bid-tid

Ensure all fluids are WARMED 37-39 DegC

Crop Volumes30ml/kg q 6-8 hrs or 3-5% bodyweightInitial to Max Crop Volumes

Finch: 0.1-0.5 q 4hrsBudgie: 0.5-3.0 q 6 hCockatiel: 1-8 q 6hSun conure: 7-15 q 6hCockatoo: 10-40 q 8-12 hrs

Oral Rehydration/Nutrition

Fluid TypesHartmann’s solution0.45% NaCl and 2.5% glucose0.9% NaClColloids eg Gelofusin (10-15 ml/kg IV q 8hrs)Fluids should be WARMED

Blood transfusionsIndicated when PCV <15-20%**Circulating Blood volume= 7-10% BWCan easily tolerate 30% acute blood lossPCV can take 24 hrs to stabiliseTransfusion volume: 10-20% blood volumeHomologous vs Heterologouss

Homologous: RBC survival 9-11 dayHeterologous: 1-3 daysReactions rare

Medication Injection SitesIntravenousIntramuscular

Pectoral musclesStart low, alternate sites

Subcutaneous eg enrofloxacin diluted with saline for

repeated injections

Dyspnoeic PatientsUpper Vs Lower Respiratory DiseaseUpper:

Open beak breathing with high pitched squeakForward leaning postureAcute- good body condition

Lower:Poor body condition- chronic?Coelomic distension

Stabilising Dyspnoeic PatientsOxygen therapyNebulisationRelieve upper respiratory obstructionCoelomocentesisOvocentesisAir sac cannulation

Nebulisation ProtocolsF10 concentrate

1ml to 250 ml tap waterNebulise 10-20 mls for 30 mins tid-qid

Acetylcysteine 20% (Mucomyst)22mg/ml sterile water

Piperacillin 10mg/ml saline 10-30 mins q 6-12 hrs

Amphotericin B

Diagnostic SamplingFaecal Exam

Wet prep, D-Q, Gram Stain Crop washBlood Sampling

Li Hep and blood smearRadiology

Lat AND VD viewsUltrasonographyEndoscopyCoelomocentesis

Assessing Urofaeces

Cardiopulmonary ArrestIntubation , 100% oxygen; PPV q 4-5 sec

Don’t overinflate birdDon’t blow into ET tube- zoonoses!!

CPRAdrenaline 0.5- 1 mg/kgAtropine 0.5mg/kgPlus fluid bolusDoxapram 20 mg/kgNaHCo3: 5mmol/Kg IV oncePrognosis is better for acute arrest eg Iso

overdose than with chronic illness

Other Emergency MedicationsAnalgesics

Butorphanol 1-2 mg/kg IM q 4-8 hrsMeloxicam 0.3-0.5 mg/kg PO, IM sid-bidTramadol 4-5 mg/kg

AntibioticsEnrofloxacin 15 mg/kg bid PO or diluted IM/SCAmox/Clav; ticarcillin- 100-150 mg/kg bidTrim/Sulph- 30 mg/kg bid

Chelating agentsCaEDTA 50-75 mg/kg IM BID

Thank You!
