Gas Anesthesia
Wildlife Rescue uses isoflurane gas anesthesia — the gold standard for avian surgery. Birds are placed under controlled anesthesia using a mask or endotracheal tube connected to a precision vaporizer, allowing the surgical team to perform complex procedures while monitoring vital signs throughout.
- Isoflurane delivered via precision vaporizer with oxygen carrier gas
- Face mask induction for smaller birds; endotracheal intubation for longer procedures
- Continuous monitoring of heart rate, respiration, and reflexes
- Rapid recovery — birds typically regain consciousness within minutes of gas removal
- Essential for fracture repairs, wound debridement, and diagnostic procedures
- Dedicated anesthesia technician monitors vitals throughout every procedure
