General anesthesia is the induction of a loss of unconsciousness by pharmacological means. In this state, the patient will be unarousable to verbal, tactile, and painful stimuli. Because of upper airway obstruction, some form of intervention, usually insertion of a laryngeal mask airway or endotracheal tube, is typically required to maintain
· General anesthetics have been widely used in surgery since 1842, when Crawford Long administered diethyl ether to a patient and performed the first painless operation.
The introduction of cocaine as the first local anesthetic (LA) in the late nineteenth century was soon accompanied by reports of its systemic toxicity. The symptoms of toxicity were frequently described as seizures or respiratory failure, but some cases also included accounts of adverse cardiac effects. Often lethal, local anesthetic systemic toxicity (LAST) was treated with caffeine, ammonia
Chapter 27, General and local Anesthetic Agents WRITTEN ASSIGNMENTS 1. What is balanced anesthesia? balanced anesthesia use of several diff erent types of drugs to achieve the quickest, most effective anesthesia with the fewest adverse effects Provide examples of drugs that may be used with balanced anesthesia This is accomplished by balanced anesthesia—the combining of several drugs,
Local anesthetics are weak bases and contain a higher ratio of ionized medication compared to non-ionized. Increasing the concentration of non-ionized local anesthetic will speed onset. In general, local anesthetics with a pKa that approximates physiologic pH have a higher concentration of non-ionized base resulting in a faster onset.
· Local anesthesia is a type of anesthesia that blocks the transmission of nerve impulses to and from a specific area of the body. It does not cause the patient to be unconscious but it can create a numbing sensation in the area where the anesthetic drug is applied and where the surgery is performed.
Anesthesia is the practice of administering medicines that block the feeling of pain or other sensations to allow medical or surgical operations to take place without causing undue distress or discomfort. There are various types of anesthesia, and most are given by inhalation (breathing in

General Anesthetics. General anesthetics are medications that induce and maintain a state of unconsciousness. They cause anterograde amnesia, meaning that a patient does not remember the events that follow their administration. This class of medications create amnesia for surgery These can be given either by IV injection or inhaled as a gas.

· In general, the safest anesthetics are inhalants used with the proper delivery and scaveng-ing systems. The most commonly used currently available inhalant anesthetics are iso-flurane, sevoflurane, and desflurane. All three have applications in animal research due to their rapid onset and offset with minimal side effects.
· General anesthesia, on the other hand, is a type of anesthesia that makes the patient fall into a state of unconsciousness. The body and brain are “asleep” so the patient has no awareness, feelings, or memory of the events while in anesthesia. Comparison Chart.

General Anesthesia General anesthesia (GA) is the state produced when a patient receives medications for amnesia, analgesia, muscle relaxation, and sedation. An anesthetized patient can be thought of as being in a controlled, reversible state of unconsciousness.
Local anesthetics have a dose-dependent negative inotropic effect. This depressant effect is directly proportional to the drugs relative potency (see chart). Patients with acidosis and/or hypoxia are at a greater risk for the cardiac depressant effects of local anesthetics.

General anesthetics are medicines that render a patient reversibly unconscious and unresponsive in order to allow surgeons to operate on that patient. General anesthetics are normally administered intravenously or by inhalation by a specialist doctor called an anesthetist who also monitors the patient's vital signs (breathing, heart rate, blood
· Chemistry of Local Anesthetics. Local anesthetics exist in ionized (cation) and unionized forms.Ionization of the drug affects its transportation across the lipid plasma membrane.The ionized form (water-soluble but lipid insoluble) of a local anesthetic is important as it is the most active at the receptor site (lipidic plasma membrane/axon).
