12 Questions
What is the primary advantage of intravenous injection of anesthetics?
Allowing for dose adjustment in the individual animal
Why is continuous intravenous infusion preferred over repeated injections?
To achieve a stable plane of anesthesia and hemodynamics
What is a benefit of continuous intravenous access?
Enabling the administration of fluids, specific antagonists, or other emergency drugs
Why is intraperitoneal administration not recommended in pregnant rodents or animals larger than rodents?
Due to the risk of abdominal organ damage
What is a limitation of intravenous injection in certain rodent species?
Difficult access to peripheral veins
What type of anesthetics is suitable for intramuscular or subcutaneous administration?
Only anesthetics with a broad safety margin
What is pain, and how does it relate to the body's defense system?
Pain is an unpleasant feeling that is an essential component of the body's defense system, providing a rapid warning to the nervous system to initiate a motor response to minimize physical harm.
What is the role of nociceptors in the process of pain transmission?
Nociceptors are pain receptors found in most bodily tissues that respond to a wide range of stimuli, and are responsible for receiving and transmitting stimulation signals to the brain, which interprets them as pain.
How does pain transmission occur, and what is the role of neurotransmitters in this process?
Pain transmission occurs through the release of chemicals called neurotransmitters by nociceptors, which course through the nerves, spinal column, and brain at very high speeds.
What is the difference between pain and nociception?
Pain is an unpleasant feeling, while nociception refers to the entire process of pain transmission, including the reception and transmission of stimulation signals to the brain.
What are the key components of the definition of pain, as described by Terman et al. (2003)?
The key components of the definition of pain include unpleasant sensory, emotional, and cognitive experiences provoked by real or perceived tissue damage, and manifested by certain autonomic, psychological, and behavioral reactions.
What is the function of pain receptors in the body, and how are they distributed?
Pain receptors, or nociceptors, are primarily responsible for receiving and transmitting stimulation signals to the brain, and are present in most parts of the body, responding to a wide range of stimuli.
Learn about the safe administration of anesthetics through intravenous injection in animals, including the benefits of continuous infusion over repeated boluses. Understand how to achieve precise control over anesthetic depth through adjusting infusion rates.
