Squirt a little magic in that hissing cats mouth January 20, Relevant Topics Veterinary anesthesia and analgesia expert Tasha McNerney makes a case for kitty magic and describes how to deliver it to particularly peevish cats. Local anesthetics work by totally disrupting neural transmission of information by axons mahic the treatment site and provide true analgesia.
Its relatively low cost and similar efficacy makes it preferential over other opioids in some cases. Cats can also be given torbugesic 0.
Otherwise, a roller-coaster effect occurs leaving the patient in varying degrees of pain between treatments. Opioids are metabolized by the liver and excreted via the mabic and should be used with caution in patients with renal or hepatic disease. The recommended dosing is 0. What are the key points about anesthetic premedication in cats?
Buprenorphine is recommended for mild to moderate pain. A recent study in the UK reported a mortality rate of 0.
All other drugs in this class are compared to morphine in terms of efficacy, duration of action, cost etc. Loco-regional anesthetic techniques are crucial in pain management.
Anesthetic considerations for cats
They provide excellent analgesia, but can have adverse effects including respiratory and central nervous system CNS maggic, gastric stimulation, bradycardia and hypotension. These lipid-soluble molecules are rapidly absorbed by mucosal, pleural, and peritoneal surfaces.
For simple non painful procedures dose can be reduced to: 0. The overall effectiveness of butorphanol as an analgesic is questionable.

Partial agonists avidly bind and partially activate mu receptors. Generally, a sedative drug is combined with an opioid for analgesia. McNerney uses buprenorphine instead of butorphanol, but she says either one works. Magid usually use the higher 0. Local and Regional Anesthetics Applying analgesia directly to the affected nerve endings can provide excellent pain control, while reducing the need for systemic drugs.
Sedation should not be considered safer than general anesthesia since some sedatives can cause ificant cardiorespiratory depression. They are usually subdued within 20 minutes.
Also, it has been recognized in human patients that there is great individual variation in responsiveness to drugs. The risk of nagic death in cats varies between 0.
While the sedative effects of butorphanol may last for 2 or more hours, the effect of analgesia is only about 40 minutes, an important consideration when managing pain of any greater duration. It is expensive compared to morphine, but has a markedly lowered incidence of respiratory depression and dysphoria. However, its additional side effects, particularly systemic hypotension and vomiting, make it less desirable in many instances. Onset of action is druga rapid in epidural administrations.
Also, NSAIDs have been shown to have synergistic effect when combined with other classes of drugs such as opioids.

Always works out to the same amount of each so is a nice double check. Butorphanol can be used to partially reverse pure agonists by blocking their action at mu receptors. Other commonly used sedatives e. Opioid drugs are classified as agonists meaning they stimulate the opioid receptors or antagonists meaning they block particular opioid receptors. Propofol can be a good choice for cardiac patients; however, in patients suspected of CHF it can reduce fractional shortening per Dr.
Maic most commonly used pure agonists in the United States are morphine, hydromorphone, oxymorphone and fentanyl.

Poor health status ASA statusage, extremes of body weight, endotracheal intubation, and the lack of anesthetic monitoring or fluid therapy are among risk factors that have been associated with peri-operative mortality in this species. Cats "Kitty Magic" for surgical or painful procedures.
A disadvantage of pure opioids is habituation necessitating ever increasing dosage to achieve therapeutic effects. Provides about 30 minutes of sedation to transition smoothly from anesthesia. Pure antagonists have the effect of reversing the narcotic properties of agonists. This is one reason that protocols for treating pain in veterinary patients have been difficult to develop.

Onset of action is from 12 to 24 hours; therefore, supplemental analgesia is recommended during the initial treatment period. Cats should have intravenous access and fluid therapy should be administered. Mu and kappa receptors are responsible for sedation, analgesia, and respiratory depression. Individual personality, breed traits, and the psychological states of fear and anxiety all seem to play a role in the animal patient's perception of pain and response to treatment.
The type of opioid is chosen based on the degree of analgesia required and the specific needs or limitations of the individual patient.
