The existence of xenon, a rare and costly noble gas, comes as a surprise to many individuals. In fact, this gas is the only one of its kind in our atmosphere. It is also used for medical imaging and as a general anesthetic. It also has the distinction of being the first noble gas to have a controlled chemical component. Plutonium, its other relative, is the stuff of nightmares. In addition, it is the only noble gas to reach the moon. In 1898, a group of English chemists at the University of Cambridge discovered it.
Xenon is not a very hazardous gas, although it does include a lot of isotopes. Some are stable, whereas others are produced by nuclear explosions. The xenon xe is also utilized to power a variety of clever devices, ranging from the tiniest to the biggest. Due to its characteristics, it is used as a source of ion propulsion for space travel.
A noble gas utilized in inhalational anesthetics is xenon. Additionally, it is a potent neuroprotectant. Its primary impact is the suppression of glutamatergic NMDA receptors in the dorsal horn of the spinal cord. It has a greater concentration of this glutamatergic action than the well-known anesthetic Nitrous Oxide.
The minimal alveolar concentration of xenon is 33% (MAC-awake). MAC-awake is the standard measure of hypnotic strength for inhalational anesthetics. The MAC is decremented by 0.2 every 15 minutes, beginning with an initial value of 0.8.
It is also the noble gas most soluble in oil. Compared to xenon, the solubility of nitrogen oxide and isoflurane is substantially lower.
For many years, xenon gas has been used in general anesthesia. Xenon offers several benefits over other powerful inhaled anesthetics, but with some disadvantages. It may raise the risk of surgical nausea and vomiting, for instance. In addition, it must be taken with an inspiratory Oxygen content of at least 30%.
The liquid xenon was explored as a possible neuroprotective drug in the 1990s. The gas inhibits the excitability of glutamatergic hippocampus synapses by selectively blocking glutamatergic hippocampal synapses. However, it has minimal impact on GABAergic inhibitory synapses.
Cullen and his colleagues were the first to employ xenon as a general anesthetic in the early 1950s. Two individuals were successfully sedated, and a single dosage of xenon was sufficient to cause loss of consciousness, the researchers said.
The minimum alveolar concentration (MAC)-awake is a standard measure of the hypnotic efficacy of inhalational anesthetics. From a maximum of 0.8 MAC, the MAC-awake is decreased by 0.1 every 15 minutes. Xenon's MAC-awake value is 33%, while isoflurane's is 0.40+/- 0.07%.
Comparing xenon anesthesia to N2O/isoflurane anesthesia, Cullen et al. found that xenon anesthesia was quicker than n2o cylinder+isoflurane anesthesia. T1 and T2 periods were reduced. The MAC-awake/MAC ratios were comparable in individuals administered xenon and N2O+isoflurane.
The second portion of the research compared the anesthetic effects of xenon-sevoflurane and nitrous oxide-sevoflurane. The MAC-awake of nitrous oxide was compared to that of a concentration of isoflurane or sevoflurane containing 0.5 times the MAC-awake. The findings were compared using Dunnett's test, and the mean + standard deviation and 95% confidence intervals were provided.
The inert gas xenon has anesthetic characteristics. It has been used in a number of applications, including lung imaging, skin lesion excision, and laser treatment. Unlike the majority of inhaled anesthetics, xenon has no effect on the kidneys or liver. Minimal sympatholytic and vagotonic effects are also seen. It has a limited supply. In spite of this, clinical interest has increased in recent years.
It has a quick and smooth inhalational induction. Xenon has a MAC-awake of 33%, which is about one-third that of N2O. Nitrous Oxide has a MAC-awake of 63.3 +/- 7.1%. The sevoflurane MAC-awake is 0.59 +/- 0.10%. Isoflurane's MAC-awake is 0.40 +/- 0.07%.
By fractional distillation of liquefied air, xenon gas, a non-explosive monoatomic gas, is produced. It is utilized in general anesthesia and radiodiagnostic treatment as an anesthetic drug. It is also used to generate a voice with a high pitch. It has also been used to treat skin blemishes and Alzheimer's disease and epilepsy have been examined with it.
Analgesic effects of xenon are mediated through suppression of NMDA receptor signaling. It is reported to exert 1.5 times more analgesia than nitrous oxide. Additionally, it has been shown that xenon inhibits the activity of the 5HT3A receptor. This receptor is involved with both peripheral and cerebral nociception.
