Desflurane mechanism of action is briefly studied. There is a dose-dependent suppression of EEG, at MAC greater than 1.66 the LEG becomes isoelectric. There is no evidence of epileptiform activity. It decreases the amplitude of somatosensory evoked potentials. There is a dose-dependent decrease in cerebral metabolism and cerebral vasodilatation. Cerebral autoregulation is impaired similar to […]
Some disadvantages of volatile anesthetics are listed here. • Poor oxygen availability is one of the disadvantages of volatile anesthetics ; hypoxic insults are poorly tolerated due to dilution of air-oxygen mixture by ethe’ vapour. • Patient breathes dry air because water vapour in the air condenses on the mask due to low temperature because
A rapid Isoflurane inhalation induction is possible with isoflurane because of low blood/gas solubility coefficient. It has a pungent odour, patients complain of burning sensation in the airway though there is no increase in airway reflexes or secretions. So a smoother induction is seen with halothane or sevoflurane which are preferred for inhalational induction. Recovery:
Introduction to Long-Term Venous Access Long-term venous access is a vital component of modern medical treatment, allowing healthcare providers to administer therapies over extended periods. This method is particularly significant in scenarios requiring frequent or continuous access to the bloodstream, such as chemotherapy for cancer patients, dialysis for those with kidney dysfunction, and long-term antibiotic
Pentazocine injection is a synthetic narcotic analgesic derived from benzomorphan. Pentazocine Potency Its analgesic potency of 30 mg is said to be equal to 10 mg of morphine or 75 to 100 mg of pethidine. Pentazocine Dose The usual dose in adults is 20 to 60 mg i.m. (about 1 mg/kg). The oral dose ranges from
Nitrous Oxide Effects the brain and induced analgesia or pain relief and anesthesia. Nitrous Oxide Effects includes the cardiovascular system as well. Nitrous oxide is a myocardial depressant and reduces the cardiac output. This is offset by an increase in sympathetic nerve activity resulting in peripheral vasoconstriction and thereby a minimal change in blood pressure.
What is Chloroform Chloroform is a very toxic compound, which was used in the past as an anesthetic agent. Chloroform use in anesthesia is only of historical value, although it still has some applications outside the medical practice. It was available as a liquid in bottles that would be poured on to a cloth and
Anesthetic Ethyl Chloride Spray is first sprayed in the mask, as it is pleasant and potent, it produces unconsciousness in 1-2 minutes. Ether is then introduced till the patient is anesthetized to Guedel ‘s stage III and plane H when respiration is regular, eye movements cease, pupils are in mid position and reflexes absent (eyelid,
These are classified as high flow Oxygen Delivery Devices and low flow Oxygen Delivery Devices. Classification of Oxygen Delivery Devices in non intubated patient : 1. High flow (fixed performance) delivery systems. 2. Low flow (variable performance) delivery systems. As the high flow oxygen delivery devices have already been discussed, let us see what the low
Enflurane Structure is a halogenated methyl ethyl ether and is an isomer of isoflurane. Enflurane structure makes it a colourless liquid, noncorrosive to aluminium, iron as well as copper, non-flammable, stable to light and UV light, does not need a chemical stabilizer. Physical properties: The bp is 56.5°C, The SVP 172 mm Hg (22.9 kPa),
