Study Notes

CPR and Defibrillation in Veterinary Medicine

Early defibrillation significantly improves survival outcomes in human cardiac arrest cases; each minute without defibrillation decreases survival chances by 10%.
In human CPR, out-of-hospital arrests are often linked with ventricular fibrillation; this rhythm is rare in dogs and cats.
Following evidence-based practices, survival rates in humans post-arrest can reach approximately 20%.

RECOVER Study Overview

The RECOVER study, managed by VECCS and ACVECC, reviewed clinical and experimental evidence for canine and feline CPR.
Developed evidence-based guidelines for CPR in dogs and cats across five key domains: Preparedness and Prevention, Basic Life Support, Advanced Life Support, Monitoring, and Post-Cardiac Arrest Care.
Identified knowledge gaps to guide future CPR research in veterinary medicine.
Guidelines and findings were published in a special 2012 issue of the Journal of Veterinary Emergency and Critical Care.

Key Concepts of Basic and Advanced Life Support

Basic Life Support involves:
- A: Establishing a patent airway.
- B: Providing positive pressure ventilation.
- C: Generating circulation through chest compressions.
Advanced Life Support includes:
- The use of medications (e.g., atropine, adrenaline).
- Electrical defibrillation and support after resuscitation.

Patient Resuscitation Considerations

Return of spontaneous circulation (ROSC) occurs in about one-third of CPR cases; effective CPR is usually a team effort.
Chest compressions can maintain circulation temporarily until professional help arrives.
Key items for a crash box include endotracheal tubes, laryngoscope, Ambu bags, IV catheters, and essential drugs like adrenaline and atropine.

Airway Management

Airway drawer in a crash box should include ET tubes, a laryngoscope, and tracheostomy tubes for upper airway obstructions.
Techniques for difficult intubation include using a stylet or performing a temporary tracheostomy.

Vasopressors and Drug Therapy

Adrenaline:
- Acts on α-adrenergic receptors to increase blood pressure and flow, and β-adrenergic receptors to enhance heart rate.
- Recommended for treating asystole and PEA; initial low doses are preferred.
Atropine:
- Useful for sinus bradycardia and AV block, but must be used cautiously to prevent rebound tachycardia.

Monitoring During Resuscitation

One team member should monitor effectiveness of resuscitation and look for signs of spontaneous circulation.
Use of ECG monitoring is recommended; palpation of the femoral pulse is routine but not always reliable.
Doppler blood pressure probes can help detect perfusion, and ETCO₂ levels provide information on successful ventilation.

Post-Resuscitation Care

Continual monitoring is crucial post-resuscitation; many patients are at risk for second arrests.
Areas of focus include oxygenation, ventilation, blood pressure, and perfusion to prevent complications like pulmonary edema.
Neurological issues may arise post-arrest but typically resolve within 48-72 hours; glucocorticoids should be avoided to prevent worsening outcomes.

Preparation for Emergency Situations

A logical, calm approach is essential during CPA situations to optimize patient outcomes and efficiency in response.
