Drugs that depress the CNS or Peripheral Nerves to produce diminution of consciousness, loss of responsiveness to sensory stimulation, or muscle relaxation. They reduce or eliminate pain by depressing nerve function in the CNS andor PNS. The state of reduced neurologic function. The loss of the ability to feel pain resulting from the administration of an anesthetic drug or other medical intervention. Two types General and Local. A drug induced state in which the CNS nerve impulses are altered to reduce pain and other sensations throughout the entire body. It normally involved complete loss of consciousness and depression of normal respiratory drive. Complete loss of consciousness, loss of body reflexes, elimination of pain through whole body, skeletal and smooth muscle paralysis including respiratory requiring mechanical ventilation to avoid brain damage. A drug induced state in which peripheral or spinal nerve impulses are altered to reduce or eliminate pain and other sensations in tissues innervated by these nerves. Elimination of pain sensation in the tissues innervated by the anesthetized nerves. The practice of using combinations of different drug classes rather than a single drug to produce anesthesia. The simultaneous combination use of both general anesthetics and adjuncts. Most commonly used to induce anesthesia during a surgical procedure through the use of one or more drugs. Induce a state in which the CNS is altered to produce varying degrees of pain relief, depression of consciousness, skeletal muscles, reflex reduction. Can either be Inhalation or parenteral anesthetics. Volatile liquids or gases that are vaporized with oxygen to induce anesthesia. Inhaled gas nitrous oxide Inhaled volatile liquids enflurane, halothane, isoflurane, methoxyflurane, and others. IV and are used for induction andor maintenance of general anesthesia,induction of amnesia, and as adjuncts to inhalation type anesthetics. Ex etomidate, ketamine, methohexital, propofol, thiamylal, thiopental. Drugs used in combination with anathetic drugs to control the adverse effects of anesthetics or to help maintain the anesthetic state in the patient. Sedative hypnotics Barbiturates, Benzodiazepines, hydroxyzine, and promethazine Opioid Analgesics fentanyl, sufentanil, meperedine, and morphine. Neuromuscular blocking drugs NMBDs Depolarizing Drugs succinylcholine, Nondepolarizing drugs pancuronium, d tubocurarine, vecuronium Anticholinergics Atropine, glycopyrrolate, scopolamine, Anxiolytics propofol, Antiemetics. The Overall effect of gerneral anesthesia is a progressive reduction of sensory and motor CNS functions, with sight going first, then taste, smell, and hearing, plus loss of consciousness. Cardiac and pulmonary are the last to be effected. Reverse when coming out All of these losses due to aesthesia become the stages of anesthesia. Varies according to drugs. Overton Meyer Theory, lipid solubility Progressive depression of cerebral and spinal cord functions. ECT electroconvulsive Therapy for depression, to produce unconsciousness, skeletal muscular relaxation, and visceral smooth muscle relaxation. Rapid onset quickly metabolized. Vary according to dosage and drug used, sites primarily effected are heart, peripheral circulation, liver, kidneys, and respiratory tract. Myocardial depression is common. Malignant hyperthermia uncommon, potentially fatal, happens with inhalation anesthesia and causes rapid increased temp, tachycardia, tachypnea, muscle rigidty. Can occur during or after general anesthesia or use of NMBC succinylcholine. Life threatening emergency. A genetically linked major adverse reaction to general anesthesia characterized by a rapid rise in body temperature, as well as tachycardia, tachypnea, and sweating. A theory that describes the relationship between the lipid solubility of anesthetic drugs and their potency. A milder form of general anesthesia that causes partial or complete loss of consciousness but does not generally reduce normal respiratory drive. Also called Conscious sedation doesnt cause complete loss of consciousness. Patients relax, reduce anxiety, but still maintain an open airway and respong to verbal commands. More rapid recovery than general. Combination of an IV benzaodiazepine and an opiate analgesic. De De Mouse Sky Was Dark Rar more. Used for daignostic procedure and minor surgeries that do not require deep anesthesia. Topical anesthesia may be applied too. Greater safety profile. Reduce pain sensation at the level of peripheral nerves, AKA regional anesthetics, blocks nerve conduction to a certain area without loss of consciousness. Render a specific portion of the body insensitive to pain. Interfere with nerve impulses transmission to specific areas of the body. Can be either topical or parenteral. Ester and amide both end in caine be alert to make sure giving the type that a patient can tolerate. Used for childbirth, dental procedures, suturing, and diagnostic procedures. Interfere with nerve conduction. Local anesthesia induced by injection of an anesthetic drug near the spinal cord to anesthetize nerves that are distal to the site of injection. Two types intrathecal or epidural. Desired in dental procedures, suturing, and diagnostic procedures. Types of Local Anesthesia. Spinal or intraspinal, infiltration, nerve block, or topical. Parental anesthetics lidocaine, mepivacaine, procaine, tetracaine, and others. Effects of Local Anesthesia. Usually limited, spinal headache sometimes treated with a blood patch, which is an injection of small volume, 1. Inadvertent intravascular injection occurs, excessive dose or rate of injection is given, slow metabolic breakdown occurs, and injection into highly vascular tissue occurs are all reasons that can make an adverse effect occur. Blocking Drugs NMBDPrevent nerve transmission in skeletal including respiratory and smooth muscle leading to paralysis. Be sure to ventilate prior to giving an NMBD Curar poison, Mainly used in the OR to control breathing during surgery but also used for diagnostic tests like laryngoscopy, bronchoscopy. DO NOT cause sedation or pain relief. Pt may be paralyzed yet conscious. Depolarizing and nondepolarizing. Succinylcholine and Pancuronium are a couple. Succinylcholine, works similarly to neurotransmitter ACh. Bind in place of ACh at the motor endplates of muscle nerves or neuromuscular junctions. Metabolism is slower than ACh, so as long as succinylcholine is present, repolarization cannot occur. Phase 1 depolarizing phase the muscles fasciculate twitch. Eventually, after continued depolarization has occurred, muscles are no longer responsive to ACh released. Phase 2 muscle tone cannot be maintained, and the muscles becomes paralyzed. Result flaccid muscle paralysis. Emergency ventilation equipment must be immediately available for useBind to ACh receptors at the neuromuscular junctions, where they block the ACh actions. Membrane never depolarized. Therefore, muscle fibers are not stimulated, and skeletal muscle contraction does not occur. Based on their duration there are short acting mivacurium, intermediate acting atracurium, vecuronium, rocuronium, and long acting drugs pancuronium, doxacurium. First sensation is typically muscle weakness, usually followed by a total flaccid muscle paralysis. NMBDs Adverse Side Effects. Few when used appropriately. Effects vary according to site.
