This article lists veterinary pharmaceutical drugs alphabetically by name. Goal: Profound sedation or complete anesthesia with a minimum of pain or stress related to medical techniques or handling. Endotracheal tubes need to have a cuff, and cuffs need to be inflated during anesthesia. Endotracheal tube sizes for 25-kg dogs are generally between 7.5 and 9 mm. 7 For anesthetic drugs, the duration of action has not been provided. An anesthetic serves three main purposes: immobilization, unconsciousness, and analgesia or pain relief. Understanding the basic physiologic effects of the anesthetics used is paramount to correctly interpreting monitoring parameters. Tiletamine/zolezepam (Telazol) is a pre-mixed cocktail of two drugs (tiletamine and zolazepam), which is employed commonly as a tranquilizer for both cats and dogs. Propofol is a respiratory depressant. Dogs may also be given induction drugs to propel them from being conscious into an unconscious state. Never restrict water.

Dose:4-8 mg/kg in unmedicated animals; 1-4 mg/kg in premedicated/sedated animalsRoute: IVComments: Slowly deliver titrated volume, as rapid administration will lead to apnea and hypotension. Etomidate is short acting and produces minimal cardiovascular changes (heart rate, An anesthetic serves three main purposes: immobilization, unconsciousness, and analgesia or pain relief. Give at least 30-45 minutes prior, to desired effect. When attempting intubation, have several sizes available and ready with appropriate ties. The #1 Veterinary Drug Calculator website and the #1 Veterinary Apps Drug Calculator! Because most anesthetic drugs cause hypotension and hyperthermia, provide supplemental heat to animals under anesthesia. Administering sedative drugs decreases excitement and causes relaxation to allow for the placement of indwelling catheters (for IV drug and fluid administration) or allow for intubation (for inhalation anesthesia). References for these guidelines are available by request. For more involved procedures, EKG, invasive pressure monitoring, and blood gas analysis may be indicated. For more complicated procedures, or if the animal is intractable, general anesthesia Prolonged recovery from propofol and other drugs; The greyhound is the only breed with a documented breed-specific sensitivity to particular anesthetic drugs. Verify proper placement of the endotracheal tube by ausculting all lung fields for strong breath sounds. Induction refers to an anesthetic administered to place an animal in an unconscious state and allow for tracheal intubation. Some drugs can provide all of these effects when used alone, but a combination of drugs is frequently used in veterinary anesthesia. The application of anesthesia is different for each animal. Dose:0.003-0.010 mg/kg IM or 3-10 g/kg0.003-0.005 mg/kg IV or 3-5 g/kg. A one-week acclimation period is recommended. This can be used as a guide for how far the tube should be inserted upon intubation. Patients should be premedicated with drugs that provide sedation and analgesia prior to anesthetic induction with drugs that allow endotracheal intubation. Thiopental is the most-commonly used barbiturate for this stage of anesthesia but other, non-barbiturate drugs have also gained popularity for anesthetic purposes. Fast animals overnight prior to an anesthetic event. A veterinarian may encounter a variety of species in his or her practice, and must have the knowledge of the effect the different veterinary anesthesia drugs may have on each patient.

Greyhounds have prolonged recoveries following anesthesia with thiopental due to a deficiency in the hepatic enzyme responsible for the first step in the metabolism of that drug. Causes hypotension when given as a bolus. In this case, many drugs have a dosage range or can be combined with additional medications if necessary. ii) Compared to acepromazine & butorphanol, this combination provides somewhat greater sedation in dogs and a stronger analgesic influence of longer duration in both dogs and cats. Standard mammalian monitoring techniques apply to dogs. In a multi-institutional British Drugs like thiopentone and propofol will be used in such cases to induce anasthesia in the dog. Because most anesthetic drugs cause hypotension and hyperthermia, provide supplemental heat to animals under anesthesia. Any of the behavior-modifying drugs prescribed to geriatric dogs can have serious, even deadly, interactions with anesthetic or analgesic drugs, Dr. Matthews explains.

A common combination is the use of opiates and tranquilizers to sedate an animal before a state of general anesthesia is induced. This involves injecting the medication into a specific place in the skin (or applying it onto an area of the skin) to induce temporary localized numbness, allowing the veterinarian to perform a brief procedure. Find guidelines for canine anesthesia, including recommended, Respiratory rate (breaths/minute) = 20-40 resting, Blood pressure = >60 mm Hg (mean) and >90 mm Hg (systolic), Mucous membranes = pink, not pale, white, gray, or blue, Advanced Research and Diagnostics Laboratory, Services for Researchers External to the University, Research & Support in the health sciences, Institutional Animal Care and Use Committee (IACUC), Research Occupational Health Program (ROHP).

Yet, when listing these drugs in an animal use protocol, drugs should be listed with approximate dose ranges. Propofol, when administered intravenously, provides a quick onset of unconsciousness but has no effect on pain, so it must be used in conjunction with an analgesic.

Find guidelines for canine anesthesia, including recommended anesthetic drugs and procedures. Etomidate is an imidazole drug used for induction of anesthesia in small animals. Anesthesia is used for a wider range of circumstances in animals than in people, due to animals' inability to cooperate with certain diagnostic or therapeutic procedures. Guaifenesin is sold over the counter as an expectorant for people, and it is used in veterinary medicine to relax the animal before a general anesthetic is administered. Current medications a dog is taking should be considered as well. If no breath sounds are heard, back the tube out until sounds are heard in all lung fields. Dogs can be intubated using a laryngoscope. The goal of monitoring is to maintain cardiovascular homeostasis and core body temperature. Note: Veterinarians and trained staff recognize when a dog may need a higher dose if the initial dosage does not sedate them enough. For example, morphine is frequently used to sedate dogs, but when administered to a horse may cause mania. The method of general anesthesia is determined by the health of the animal, the procedure, and the experience of the surgeon/anesthetists. Calculators for Emergency and Anesthetic drugs, Constant Rate Infusions (CRI), IV Fluid Rates, Chocolate Toxicity, Calorie requirements for dogs and cats and Unit conversion (including Weight, Temperature, Body Surface Area, mg to ug, cc's to ounces's, cm's to inches). The original problem drug in sighthounds was a barbiturate, thiopental, which is used to induce anesthesia, Dr. Court says. Anesthetics affect different species in different ways, so a drug that will be safe and effective on one type of animal may be harmful to another. It is used during veterinary surgery, and is often required for diagnostic procedures since animals usually wont remain still long enough for certain tests to be performed. Dose:Acepromazine 0.02-0.05 mg/kg + Butorphanol 0.3-0.44 mg/kg IM, Dose:Midazolam: 0.10-0.20 mg/kg+Butorphanol: 0.1-0.40 mg/kgRoute:IM/IV.

All surgical procedures, anesthetics, analgesics, antibiotics or other medications used on animals must be approved by the IACUC, described in the animal use protocol, performed by personnel listed on the protocol, and appropriately trained for the surgical procedure. i) Combination of phenothiazine tranquilizer and fentanyl, hydromorphone, methadone, morphine, or oxymorphone. Benefits of administering local anesthetics, opioids, and alpha2 agonists into the epidural space include the use The most common sites for catheter placement are the cephalic and lateral saphenous veins. Treatment with more than one drug at a time will often improve a dogs response to sedation. Supplemental heat sources include circulating water blankets, air heating devices or commercial products that can be heated up or create heat via a safe chemical reactions.
