A common question that arises while studying respiratory physiology is what is minute ventilation and minute volume. The minute ventilation is the amount of air a person breaths in a minute. The minute ventilation is calculated by the multiplication of the tidal volume and the respiratory rate. What is minute ventilation? The normal tidal volume […]
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:
Halothane Anesthesia is an alkane, halogenated hydrocarbon introduced in 1256. (M Johnston, UK). Physical Properties: Halothane Anesthesia is colorless, sweet smelling, nonirritating, bp 50 degrees C, VP 243 mm Hg, blood/gas 2.5, oil/gas 224, metabolism 20—40%, MAC in 02 ofQ7 /o and 0.29% with N20. It is relat Istable, decopcs on exposure tq.ajr, hence stored
Cyclopropane is an anesthetic inhalational agent. It is a liquid agent stored in orange colored cylinders at 75 psi and delivered as gas. Among other halogenated inhalational agents used in anesthesia, Cyclopropane is one which is stored in cylinders at room temperature. Some of the important properties and characteristics of it are discussed below. • It is
General Anesthesia mask is used to ventilate the patient without intubation or before intubation. The mask significantly increases amount of dead space. These are available in sizes from 0 to 4 numbers. Face mask should be made of antistatic rubber. At the bottom of General Anesthesia mask there is air filled cuff which has soft cushioning effect.
When it comes to undergoing hip surgery, one of the critical decisions to make is the choice of anesthesia. Anesthesia plays a crucial role in ensuring a safe and comfortable surgical experience. Two common options for hip surgery are general anesthesia and regional anesthesia. In this article, we will explore the differences between these two

The metabolism of Sevoflurane complications yields fluoride ions, which if greater than 50 tmol/Iit is toxic. However, there are no reports of renal toxic effects. Compound A which is a degradation product when exposed to sodalime is also nephrotoxic, however this has not been clinically reported. It is safer to use flows greater than 2
Desflurane undergoes very little desflurane metabolism because of low blood/gas and low blood/tissue solubility. However, 0.02% is metabolized during desflurane metabolism with the production of trifluoroacetic acid which may interact with hepatic proteins and induce an immune response in susceptible patients. Previous exposure to halothane may produce antibodies. In desflurane metabolism , the elimination is almost exclusively by
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),
Postoperative Nausea and Vomiting (PONV) is one of the most distressing experiences associated with surgery, and many patients find it more troublesome than postoperative pain itself. It is not only very uncomfortable to the patient in the postoperative period but it also delays the time of starting enteral feeding and normal functions. Especially in day care
