Bednarski et al. (2011) stated that preanaesthetic evaluation including physiological parameters of the patient would explain the individual risk factors and selection of anaesthetic for surgery. Geriatric dogs, because of altered respiratory and cardiac rate, were in anaesthetic risk. For young dogs, anaesthetic risk was hypoglycemia, hypothermia and decreased drug metabolism. Brachycephalic dog breeds were more prone to upper airway obstruction. Grey hounds had longer recovery time with Propofol.

2.3 PREMEDICATION IN DOGS
Stegmann and Bestera (2001) stated that intravenous premedication with Midazolam for Propofol anaesthesia would produce behavioural changes in dogs. It also reduced the dose required for the anaesthetic induction with Propofol. …show more content…
Premedication decreased the anxiety, provided muscle relaxation, analgesia and sedation which helped the veterinarians for restraining of the animal and would also decrease the cardiovascular side effects.
Narayanan et al. (2011) opined that premedication with Midazolam, glycopyrrolate and xylazine provided smooth anaesthetic induction, easy passage of endotracheal tube and provided uneventful recovery. Depth of anaesthesia without premedication was unsatisfactory for laparotomy in

    Anesthesiologist Research Paper

    Carlie Fleming Mrs. Stanley English 12 27 October 2016 An Anesthesiologist Anesthesiologists are physicians who administer and determine what type of anesthetic treatment is to be used for the patient prior to surgery, as well as positioning the patient on the operating table in a manner that will be helpful to the surgery. Following strict medical guidelines, the anesthesiologist takes into account the patient’s current health, any medications they are taking, and the type of surgery that is being performed. While the surgery is taking place, the anesthesiologist monitors the patient’s critical life functions to make sure no complications arise. After the surgery is over, the patient’s well-being has to be monitored as the anesthetic wears…

    Etomidate Research Paper

    Etomidate, which is an imidazole derivative and an ester, is the most commonly used anesthetic induction agent and characterized by rapid onset, with minimal side effects on cardiovascular and respiratory functions, as well as minimum histamine release. These properties make it especially useful for cardiac-compromised patients. [7] However, it can suppress adrenal function through blockade of 11β-hydroxylase. This suppression persists for at least 24 hours, and some authors suggest that it may last up to 72 hours. This could harm patients with critical illness such as severe sepsis or septic shock.…

    Emergence Delirium (ED): A Case Study

    This is certainly the case at North Arkansas Regional Medical Center, where children routinely receive oral midazolam 0.5mg/kg in the outpatient holding area 15 to 30 minutes prior to being taken to the operating room for induction of general anesthesia. Midazolam has been shown to reduce parental separation anxiety and to facilitate the induction of general anesthesia but is not effective in reducing the incidence of ED (El Batawi, 2015)‌. Another sedative, dexmedetomidine, is a novel drug that is being added to our anesthesia department's armamentarium this week for trial in our pediatric population. Dexmedetomidine is an alpha-2 adrenergic agonist that is eight times more selective for the alpha-2 receptor than is clonidine. This medication possesses many qualities that make it favorable in the outpatient setting: anxiolysis, analgesia, preservation of respiration, and reduced incidence of ED following general anesthesia (Gertler, Brown, Mitchell, & Silvius, 2001)Click and drag to move‌. This promising drug has an intranasal bioavailability of 65 percent and does not cause discomfort when administered via this route. (Iirola et al., 2011)Click and drag to move‌.

    The Importance Of Sedation In Dental Procedures

    It is critical for patients undergoing any dental procedure that they are made aware of all the options available to them for having their treatment carried out. For many people having to undertake dental treatment is a very unpleasant prospect. We see people every day with varying levels of apprehension from the slightly anxious to those with a severe phobia. Good sedation practice requires the consideration of a range of non-pharmacological and pharmacological methods of anxiety management in planning treatment for each individual patient. For some patient’s treatment under Local anaesthesia alone is not possible making them ideal candidates for intravenous sedation.…

    Role Of Functionalism In Animal Testing

    Animal testing has been around since ancient times. Ancient greek and Romans tested different medical procedures on animals purely to satisfy curiosity. Because anaesthetics were not discovered until near the end of the nineteenth century, all of these experiments were tested on animals without pain relief. Anyone that has accidently stepped on their dog’s paw, knows that animals definitely feel pain. Back in the 1500’s there was an Anatomy and Physiology professor, named Andreas Vesalius.…

    In the veterinary field, numerous drugs are used on animals and different types of drugs have various effects on the body. These drugs have primary uses in practice but may have various other effects on the body that allow them to be used for multiple reasons. They may also have negative effects and are therefore contraindicated depending on the patient, patient’s condition, or species. Some drugs may act similarly or differently but have comparable effects and similar purposes. Two drugs used in veterinary patients are Potassium Bromide and Phenobarbital.…

    An Argument For Animalism Analysis

    In the essay “An Argument for Animalism” by Eric T. Olson, he concludes that personal identity is psychological continuity. I will disagree with Olson’s ideas about personal identity in the brain-transplant and the thinking-animal argument. The main point of the paper is about animalism. Olson’s argument is that each one of us is numerically identical to a human animal. Olson says that a person could exist who is not numerically identical to any animal, but it’s not the case for you and I. Olson, then presents his ‘Thinking-Animal Argument’ and the alternatives to that.…

    Tracheal Intubation Essay

    Introduction Anesthesia in obese patients is associated with difficult mask ventilation, rapid desaturation, and difficult intubation1,2. Practice guidelines for management of the difficult airway reported by the American Society of Anesthesiologists (ASA) advise that ‘multiple airway features should be assessed’3. EL-Ganzori simplified risk index (EGRI) combines and stratifies seven variables derived from parameters and observations individually associated with difficult intubation, a score more than 4 has been used as the definition of difficult intubation in different populations4. In spite of the development of numerous airway devices in the past two decades, a recent British survey concluded that difficulty with tracheal intubation is…

    All Animals Are Equal, And Speciesism Analysis

    In comparison of “All Animals Are Equal and Moral Standing,” the “Value of Lives, and Speciesism” the key differences are based on the values outlined by the writers. In Value of Lives and Speciesism, Frey discusses the importance of animals feel pain and suffer just as humans do, but also admits that there are reasons such as necessary medical research for harming animals. On the other hand, Singer’s All Animals Are Equal focuses on the rights of hemostats in comparison to those who can make intelligent decisions. The question is should non-human animals have rights and how far do those rights reach? Both agree that animals should have rights, but their major differences including, pleasure and pain, hierarchy, consumption, and richness of life.…

    Modern Day Anesthetics

    The use of anesthesia has come a long way since then, but this breakthrough has provided modern-day anesthesia a step in the right direction. Today, Chloroform and Sulfuric Ether are not used during operations, due to the fact that Ether is highly flammable and Chloroform leaves unwanted side effects. Instead, anesthesiologists use a variety of other anesthetics that suits both the surgery and the patient. Although we do not use the same anesthetics today or administer it the way we used to, the anesthetics played a big role in developing…

    INTRODUCTION: Ever since its discovery, Electro Convulsive Therapy (ECT) has continued to occupy a central place in the armamentarium of psychiatrists inspite of advances in psycho pharmaco therapy. Despite both medical and legal opposition it is still widely practiced as one of the cheapest, safest and yet one of the most effective therapeutic technique in the whole of medical sciences. Due to trauma caused to the patient physically and psychologically with unmodified direct electro convulsive therapy in the past it has now been modified with anaesthesia. The aim of ECT is to produce a grand mal seizure.…
