  • The Effect of Morphine-Lidocaine-Ketamine
    THE EFFECT OF MORPHINE-LIDOCAINE-KETAMINE- DEXMEDETOMIDINE CO-INFUSION ON MINIMUM ALVEOLAR CONCENTRATION OF ISOFLURANE IN DOGS Thesis Presented in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Graduate School of The Ohio State University By Lisa Michelle Sams, D.V.M. Graduate Program in Comparative and Veterinary Medicine The Ohio State University 2011 Thesis Committee: Dr. Phillip Lerche, Advisor Dr. Richard M. Bednarski Dr. John A.E. Hubbell Copyright by Lisa Michelle Sams 2011 ABSTRACT The purpose of this study was to determine the effects of an infusion of dexmedetomidine, a co-infusion of morphine-lidocaine-ketamine (MLK), and a co- infusion of dexmedetomidine-morphine-lidocaine-ketamine (alpha-MLK) on minimum alveolar concentration (MAC) of isoflurane in dogs. The MAC of an inhalant anesthetic required to prohibit purposeful movement is a measure of anesthetic potency (Eger et al 1965). Isoflurane is the most commonly used inhalant anesthetic in veterinary practice (Lozano et al 2009), but has potent vasodilatory effects and causes a dose-dependent decrease in mean arterial pressure in anesthetized dogs (Steffey and Howland 1977). Additional drugs are used during anesthesia to decrease the inhalant anesthetic requirement, a concept referred to as balanced anesthesia. Each of the drugs we infused has a different central nervous system receptor mechanism of action. Co-infusion of MLK, as well as the infusion of each drug separately, has been shown to reduce MAC in isoflurane-anesthetized dogs (Muir et al 2003). Dexmedetomidine, an alpha-2 agonist, has been shown to reduce isoflurane MAC in dogs (Pascoe et al 2006).

  • Hallucinogens
    Hallucinogens What are hallucinogens? Hallucinogens are a diverse group of drugs that alter a person’s awareness of their surroundings as well as their own thoughts and feelings. They are commonly split into two categories: classic hallucinogens (such as LSD) and dissociative drugs (such as PCP). Both types of hallucinogens can cause hallucinations, or sensations and images that seem real though they are not. Additionally, dissociative drugs can cause users to feel out of control or disconnected from their body and environment. Some hallucinogens are extracted from plants or mushrooms, and some are synthetic (human- made). Historically, people have used hallucinogens for religious or healing rituals. More recently, people report using these drugs for social or recreational purposes, including to have fun, deal with stress, have spiritual experiences, or just to feel different. Common classic hallucinogens include the following: • LSD (D-lysergic acid diethylamide) is one of the most powerful mind-altering chemicals. It is a clear or white odorless material made from lysergic acid, which is found in a fungus that grows on rye and other grains. LSD has many other street names, including acid, blotter acid, dots, and mellow yellow. • Psilocybin (4-phosphoryloxy-N,N- dimethyltryptamine) comes from certain types of mushrooms found in tropical and subtropical regions of South America, Mexico, and the United States. Some common names for Blotter sheet of LSD-soaked paper squares that users psilocybin include little smoke, magic put in their mouths. mushrooms, and shrooms.
