The American Society for the Prevention of Cruelty to Animals® (ASPCA®) was the first humane society to be established in North America and is, today, one of the largest in the world.
Our organization was founded on the belief that animals are entitled to kind and respectful treatment at the hands of humans and must be protected under the law. Headquartered in New York City, the ASPCA maintains a strong local presence, and with programs that extend our anti-cruelty mission across the country, we are recognized as a national animal welfare organization. We are a privately funded 501(c)(3) not-for-profit corporation, and are proud to boast more than 2 million supporters across the country.
The ASPCA’s mission, as stated by founder Henry Bergh in 1866, is “to provide effective means for the prevention of cruelty to animals throughout the United States.”

Sensitivity To Anesthesia - Issue Description
Sensitivity To Anesthesia
Anesthesia, Veterinary Anesthesia
Veterinary anesthesia is anesthesia performed on animals (excluding humans) performed by a veterinarian. Anesthesia is used for a wider range of circumstances in animals than in people, due to animals' unwillingness to cooperate with certain diagnostic or therapeutic procedures. Veterinary anesthesia includes anesthesia of the major species: dogs, cats, horses, cattle, sheep, goats, and pigs, as well as all other animals requiring veterinary care such as birds, pocket pets, and wildlife.
The most important safeguard comes prior to the administering of the anesthetic. Your vet can perform a blood panel to determine the likelihood of potential problems. Since anesthetics are eliminated from the blood stream, through both the liver and kidneys, these functions should be checked. Your vet should also be made aware of any existing or previous health problems, such as respiratory problems or heart murmurs. This allows your vet to be prepared should problems develop during anesthesia and surgery.
Specialization In Anesthesia
In North America, the American College of Veterinary Anesthesiologists is one of 20 specialty organizations recognized by the American Veterinary Medical Association. The ACVA was recognized by the AVMA in 1975, despite attempts by the AVMA to include anesthesia as a subspecialty of surgery or medicine. As of 2007, there are 156 Diplomates of the ACVA. To become an ACVA board-certified Diplomate, veterinarians must be involved in at least one year of clinical practice followed by three years of residency in anesthesia supervised by ACVA Diplomates, have accepted for publication a scientific peer-reviewed research article, and pass both a written and oral examination.
In Europe, the European College of Veterinary Anesthesia and Analgesia is one of 21 specialty organizations recognized by the European Board of Veterinary Specialisation.
Evidence exists that suggests that anesthesia which is supervised by a qualified technician is safer than anesthesia without a technician. In most private veterinary practices, the technician administers and monitors anesthesia with supervision from the attending veterinarian. In many academic institutions, anesthesia technicians are involved in working with and teaching veterinary students as well as supervising anesthetized cases. The Academy of Veterinary Technician Anesthetists is a provisional specialty academy of the North American Veterinary Technician Association and is responsible for licensing technicians as being specialized in anesthesia. For a technician to become specialized, they must be a licensed technician in their state, accumulate 6000 hours of work in veterinary medicine (at least 75% of which must be in anesthesia), 40 hours of continuing education related to anesthesia, demonstrate proficiency in anesthesia skills, and pass a comprehensive written examination.
Application In Animals
Anesthesia is required for many surgical procedures which require the patient to be immobile, unaware, and without pain. In addition, certain diagnostic procedures require anesthesia, notably stomach or airway endoscopy, bone marrow sampling, and occasionally ultrasound. Aggressive animals may require anesthesia in order to handle and perform a physical exam or obtain blood for testing. Exotic animals frequently require anesthesia for simple procedures (such as taking a radiograph or catheter placement) due to lack of domesticity. Animals may require anesthesia for therapeutic procedures, such as urinary catheterization to relieve obstruction, injection into a mass, or removing fluid from the eye to treat glaucoma.
In addition to anesthesia, analgesia is often managed by anesthesiologists or is included in the considerations for anesthesia.
Techniques In Small Animals
Cats and dogs are frequently anesthetized for surgical procedures. Small animals are most often placed under general anesthesia due to the types of procedures typically performed, the small size of the patient, their suitability to general anesthesia, and the greater degree of control. A balanced anesthesia protocol can be used whereby different drugs with different effects are used so that a high dose of just one drug can be avoided. For example, combining a sedative and an opioid will permit less inhalant anesthesia to be used, improving cardiovascular stability. A one year study in a teaching hospital shows that dogs and cats typically experience a 1 in 9 chance of anesthetic complications, with a 1 in 233 risk of death. A larger scale study states the risk of death in healthy dogs and cats as 1 in 1849 and 1 in 895 respectively. For sick dogs and cats, it was 1 in 75 and 1 in 71 respectively. For rabbits, the risk were 1 in 137 and 1 in 14 respectively for the healthy and sick groups.
Techniques In Horses And Ruminants
Many procedures can be performed in the standing horse with heavy sedation alone. Some procedures may require general anesthesia due to the location of surgery (for example, castration). Other procedures in horses require general anesthesia using an inhalant anesthetic. Horses, due to their complex physiology as performance animals, suffer a number of difficulties that can complicate anesthesia. This results in horses having a higher risk of perioperative fatality - approximately 1 in 100.
Most procedures in ruminants can be performed standing under sedation and/or local anesthesia. This strategy is manageable due to the types of procedures being performed, the larger size of the patient, the relative difficulty of general anesthesia, and the cost of the procedure versus the product value of the animal.
Most anesthetic agents used in human medicine are used in veterinary medicine. Alpha-2 receptor agonist drugs such as xylazine, romifidine, detomidine, and medetomidine, are used frequently in veterinary species (particularly large animal), but are rarely used in people. Guaifenesin is used as a muscle relaxant prior to anesthesia induction in some animals. Propofol is rarely used in large animals due to the cost. Butorphanol is rarely used in people but is commonly used in all species. Ketamine, used in children for anesthesia, is used extensively in many species to induce anesthesia or cause heavy sedation. Expensive agents, such as etomidate and desflurane are rarely used outside of university hospitals. Different species have different responses to drugs. For example, horses may experience mania with morphine whereas dogs typically become sedated. Rabbits and guinea pigs are well sedated with midazolam, which can occasionally excite dogs and cats.

Jeff Gold, Founder, Rescue Me! Animal Rescue Network
Jeff Gold lives in Watkinsville, Georgia on the same property as Rescue Me's Animal Rehabilitation Center, with 18 rescue animals. Shown with him in the photo to the left are Maggie, Izzie and Cortez. In 2003, after learning there was nobody doing boxer rescue work in Georgia, Gold founded Boxertown, an organization which helped find homes for over 500 boxers during its first two years. Based upon this success, Gold came up with the vision for Rescue Me! ― a network which helps all breeds of dogs, cats and other animals find good homes, anywhere in the world. RescueShelter.com is also a free service of Rescue Me! and provides the world's largest and most up-to-date directory of animal rescue organizations for all breeds of dogs, cats and other animals, including a comprehensive directory of wildlife rehabilitators in over 150 countries.
