Emergency and Critical Care of Sick Birds
Stacey Gelis BVSc(Hons) MACVSc ( Avian Health)Animal Referral Hospital

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!
