Monticelli, in Encyclopedia of Toxicology Third Edition Diethyl ether CAS is a component of starting fluids and is used as a solvent in the manufacture of synthetic dyes and plastics. Because of its characteristics diethyl ether was widely used in many countries as an anesthetic agent, but was then replaced by other substances in the s. The main route of exposure is inhalation. The mechanism and site of action of diethyl ether are still not known in detail. The effects of diethyl ether on the central nervous system are mainly attributed to interactions with neuronal membranes and ion channels.

What does the drug ether do E. Hugh C. Hemmings Jr. Diethyl ether ether is notable for its high aqueous solubility compared to other anesthetic ethers. Ether is sweet smelling and mildly pungent; while it can be used for inhalational induction, an ether induction is very slow and risks laryngospasm. Ether is still used as an anesthetic in some developing countries because of its low cost and high therapeutic index with minimal cardiac and respiratory depression. Its explosive flammability has eliminated its use in most developed nations.

Ether is not a cardiac depressant What does the drug ether do maintains the baroreceptor reflex, making it relatively safe in patients with septic shock. Ether has a high incidence of PONV. Chloroform trichloromethane is a sweet smelling volatile anesthetics that can be used for inhalational induction.

While initially developed as an alternative to ether, chloroform was abandoned due to its association with hepatotoxicity and fatal cardiac arrhythmias.

Chloroform trichloromethane is a sweet-smelling volatile anesthetic that can be used for inhalational induction. Although it was initially developed as an alternative to ether, chloroform was abandoned because of its association with hepatotoxicity and fatal cardiac arrhythmias. Diane J. Margaret A. Ether ethyl ether, diethyl ether, ethyl oxide is largely of historical interest and is seldom used today because it requires special precautions for safe use due to its explosive and inflammable characteristics Morch et al.

Ether may be used by an open-drop or chamber method because of its low volatility relative to more modern anesthetics such as isoflurane. Safe use requires storage in an explosion-proof refrigerator to slow degradation within the supply container and off-gassing of animal carcasses in a fume hood to allow volatile peroxides to dissipate after ether anesthesia and prior to carcass disposal. Ether is also not favored because it is a respiratory irritant and causes increased respiratory secretion Nielsen et al. When institutional safety policies allow the use of ether, it is utilized because of precedent for its use in some fields and because of its relative safety for the animal when administered by open-drop methods.

Some institutions may allow ether to be used for anesthesia of obese and diabetic mice if a vaporizer for isoflurane is not available. It has been recommended that atropine should be administered to mice or rats prior to induction with ether, although atropine is short-lived in rodents Clifford, ; Poole, Ether is relatively inexpensive and has minimal physiological effects on some parameters, although hypothalamic function may be inhibited and there may be effects on the liver Flecknell, a ; Kobayashi, Because ether abolishes the corneal blink reflex, eyes of anesthetized animals should be treated with ophthalmic ointment.

Differences in ether susceptibility have been reported among strains of inbred mice Kobayashi, The use of ether for guinea pigs and gerbils is not recommended due to breath-holding in guinea pigs Hoar, and rapid induction in gerbils Poole, Diethyl ether is obsolete as a general anesthetic [ 1 ]. It is highly inflammable and therefore incompatible with modern surgical and anesthetic techniques. It has an unpleasant smell and irritates mucous membranes; this can cause coughing, straining, laryngeal spasm, and hypersalivation.

Liver damage is as frequent as with halothane. Ether raises intracranial pressure and can cause convulsions. It can cause impaired immune responsiveness and contact dermatitis has been reported, together with a systemic allergic reaction [ 2 ]. Diethyl ether SED-9, is obsolete as a general anesthetic 1.

It can cause impaired immune responsiveness and contact dermatitis has been reported, together with a systemic allergic reaction SEDA-5, Diethyl ether has a long history in human and veterinary medicine as an anesthetic. Although it produces reliable anesthesia in mammals, it is extremely flammable. Its vapors are denser than air, and will accumulate if proper ventilation is not present.

Simple static electricity can ignite the ether vapors. Diethyl ether should only be used inside a fume hood, and thus is not recommended for use in fish anesthesia. Chloral hydrate is a sedative that has been used extensively in veterinary medicine, particularly in equine patients. It produces sedation and muscle relaxation but does not produce analgesia or anesthesia, and therefore it is not recommended as an anesthetic agent for fish. Urethane has ly been used in the laboratory setting to anesthetize laboratory animals and fish.

Halothane is a volatile anesthetic that has been used extensively in human and veterinary medicine, and can be used successfully to anesthetized fish. In people, hepatitis has been reported following exposure to halothane Stoelting, As discussed ly, anesthesia of fish produces a ificant amount of environmental exposure to the agent.

Thus, halothane is not recommended for this purpose due to the risks associated with human exposure. Chlorobutanol has been used successfully to anesthetize fish, but has been reported to be toxic in small fish Canadian Council on Animal Care, It poses human health hazards as it is irritating to skin and eyes. Inhalation of large quantities can cause unconsciousness Thorsteinsson, Since it provides no benefit over other available agents, it is not recommended for use.

Diethyl ether Figure 1 is a potent anesthetic whose actions are accompanied by analgesic and muscle relaxant activity. It has a long induction period and is highly flammable and explosive. Chloroform Figure 1 is a halogenated hydrocarbon that, unlike etheris not flammable but has ificant toxicity, including carcinogenicity, hepato- and nephrotoxicity. Barbiturate anesthetics include sodium thiopental, thiamylal, and methohexital Figure 1. While these agents have demonstrated enantioselective effects, they are typically used as racemates.

Barbiturates reduce cerebral metabolism leading to decreases in cerebral blood flow and intracranial pressure.

They also produce respiratory depression and can elicit dose-dependent decreases in blood pressure. Cyclopropane Figure 1 was discovered as a contaminant of propylene that was being investigated for its anesthetic potential in Like etherit is an explosive gas and has been largely replaced by newer generations of inhaled anesthetic. Michael J. Clomiphene isomers, in addition to metabolites, have been extracted using tert -butyl methyl ether MTB [ 21 ]. In a standard extraction, MTB 12 mL was added to a 3 mL plasma sample in a screw-top centrifuge tube, and subjected to end-over-end rotation at 50 rpm for 30 minutes.

Chloroform also has been used to extract clomiphene and its metabolites from both bile [ 22 ] and plasma [ 15 ]. Kinjal N. Diethyl ether C 4 H 10 O is a flammable, volatile, and colorless liquid with a sweet taste and characteristic odor. When exposed to fire or heat, ether releases carbon monoxide CO ; exposure to light causes ether to break down into flammable peroxides.

The MAC of ether is What does the drug ether do. Because of the explosive nature of ether, the National Fire Protection Association has given it a flammability rating of 4, corresponding to an extreme fire hazard. Anesthesia induction occurs at a concentration oftoppm and is maintained with 50, ppm. The effect of ether is dose-dependent. Symptoms consist of skin, eye, and mucosal irritation leading to an increase in bronchial secretions.

Dizziness, drowsiness, bradycardia, hypothermia, or acute excitement may also occur. Laryngospasm, loss of consciousness, and death may result. The aftereffects of emergence from ether-induced anesthesia include nausea, vomiting, and headache. Newer ethers are halogenated and include enflurane, desflurane, and sevoflurane. They are not flammable, have fewer side effects, are efficient as anesthetic agents, and cause less end-organ damage. Download as PDF. Set alert. About this. Diethyl Ether F.
