This study presents a new, low-cost anesthesia device for small laboratory animals. The improved equipment offers safe and stable anesthetic management for research and teaching purposes.

Area of Science:

  • Veterinary Anesthesiology
  • Laboratory Animal Science

Background:

  • Traditional vaporizers pose challenges for anesthetizing small laboratory animals.
  • A need exists for cost-effective, versatile anesthesia equipment for ethical research and teaching.

Purpose of the Study:

  • To develop and evaluate an improved, low-cost anesthesia device for small laboratory animals.
  • To ensure the equipment is practical, versatile, and suitable for ethical, teaching, and research applications.

Main Methods:

  • A novel anesthesia apparatus was designed, incorporating a vaporizer, unidirectional valve, water cylinder, flow regulators, and modified mask.
  • Thirty Wistar rats were anesthetized using Ether, Halothane, or Sevoflurane with the new device.
  • Anesthetic induction time, breathing rhythm, and recovery time were monitored.
