The discovery of anesthesia Inhalation agents heralded the era of modem anesthesia. In 1842, the first general anesthetic administered was recorded by CF Long and W Clarke using diethyl ether; however, they did not publicize it. The first successful public demonstration of anesthesia Inhalation agents was by W.T.G. Morton on 10th October 1846 at the Massachusetts General Hospital Boston, […]
The reduced cerebrovascular resistance at the site of Arteriovenous Malformations AVMs lead to an increase in blood flow to this area and the formation of a lower resistance shunt along with peri-infarction oedema. They usually represent a high-flow and low-resistance shunts with systemic arterial pressure more than the vascular intramural pressure ; so, rupture does
Some of the Enflurane side effects are studied below. There is a narrow margin of safety between adequate anaesthesia, unacceptable hypotension and myocardial depression. One of the enflurane side effects includes the seizure activity is rare and without sequelae. Hepatic dysfunction is rare but cross sensitization with other volatile inhalation agents possible. With prolonged anaesthesia
Patients with primary neurodegenerative undergoing Anesthesia in Neurological Disease (Parkinson’s disease, Huntington’s chorea, Alzheimer’s, amyotrophic lateral sclerosis ) or demyelinating diseases (Guillain-Barre’ syndrome, multiple sclerosis, myeloneuropathies) suffer from progressive and sometimes incurable neurologic impairment, neuromuscular involvement, dysautonomia and pulmonary insufficiency. Elective surgery should be scheduled to coincide with periods of remission along with right application
There is very little airway irritation, hence used for inhalation induction especially in children. One of the halothane respiratory effects is that it is a potent respiratory depressant, reduces tidal volume and alveolar minute ventilation. The ventilatory response to raised Paco2 and reduced Pao, may be reduced due to depression of peripheral chemoreceptors in the
In severe lung infections, the respiratory system is significantly compromised, making it difficult for patients to get enough oxygen into their bloodstream and remove carbon dioxide. This can lead to respiratory failure, a life-threatening condition where the body’s vital organs do not receive the oxygen they need to function properly. Mechanical ventilators, also known as

Halothane is a widely used inhalational agent. Physical Properties of Halothane : It is colorless liquid, volatile anesthetic. Pleasant to smell so excellent for induction in children. Stored in amber colored bottles and contains thymol 0.01% as preservative (to prevent decomposition by light). Non inflammable, non explosive. Nonirritant, so induction is very smooth. Boiling point
In Isoflurane cardiac function , the effect is that the cardiac output is maintained due to the slight increase in heart rate reflexly due to hypotension. There is a dose-dependent decrease in arterial pressure due to peripheral vasodilatation and myocardial depression, less than that due to halothane. There is a selective coronary vasodilatation and decrease
Methoxyflurane even though being the most potent anesthetic gas to be discovered till now, its use can been restricted due to the different complications that can arise from its usage. Below is a brief discussion on this inhalational agent. Physical Properties of Methoxyflurane • It has sweet odor. • It is non irritant. • It
The growth is reflected in the specialty of Neuroanesthesia Monitoring . These advances result in an abundance of data on which the treating physician can base his clinical decision. Every branch of medicine is advancing at a fast pace with the introduction of newer diagnostic modalities, treatment options and identification of more reliable prognostic indicators.
