Why is isoflurane used in cardiac surgery?
Although arterial and systemic blood pressure decline with the use of isoflurane, cardiac output is preserved as the result of an active carotid baroreceptor reflex and decreased afterload. In fact, in contrast to other volatile agents isoflurane may result in the greatest decrease in systemic vascular resistance.
Is isoflurane easily vaporised?
Enflurane and isoflurane could not be separated satisfactorily by gas chromatography. Halothane, when mixed with enflurane or isoflurane, enhanced vaporization of each agent, as well as being somewhat more easily vaporized itself.
What type of anesthesia is used with LMA?
Laryngeal mask airway (LMA) insertion is facilitated by sedation. Propofol (Diprivan) or midazolam (Versed) are acceptable choices. For elective ventilation in the operating room, less anesthesia is typically required for insertion and maintenance of the LMA than for endotracheal intubation.
Is propofol a MAC anesthesia?
Propofol is an intravenous (IV) sedative-hypnotic agent that can be used for initiation and maintenance of Monitored Anesthesia Care (MAC) sedation, combined sedation and regional anesthesia, induction of general anesthesia, maintenance of general anesthesia, and intensive care unit (ICU) sedation of intubated.
What is MAC surgery?
Monitored anesthesia care (MAC) means that an anesthesia specialist will care for you during your surgery. He or she will make sure that you get only the level of anesthesia you need to prevent pain for your specific case. MAC can be used instead of always giving general or regional anesthesia.
What is the anesthetic of choice for a cardiac patient?
Etomidate is usually the induction drug of choice for patients in severe heart failure.
What anesthetic is used for open heart surgery?
General anesthesia is used for major operations, such as a knee replacement or open-heart surgery, and causes you to lose consciousness.
Which drug would be used in a vaporizer on an anesthetic machine?
It evaporates a chamber containing desflurane using heat, and injects small amounts of pure desflurane vapor into the fresh gas flow. A transducer senses the fresh gas flow.
What is considered MAC anesthesia?
Also known as monitored anesthesia care or conscious sedation, MAC anesthesia is a type of sedation where you remain aware of your surroundings and stay calm. The anesthetist administers it through an IV into the skin and muscle around the area on which surgery will be performed.
