++ General anesthesia is a state characterized by unconsciousness, analgesia, amnesia, skeletal muscle relaxation, and loss of reflexes. Drugs used as general anesthetics are CNS depressants with actions that can be induced and terminated more rapidly than those of conventional sedative-hypnotics.
What drug is used in Anaesthesia?
Propofol is one of the most commonly used intravenous drugs employed to induce and maintain general anesthesia. It can also be used for sedation during procedures or in the ICU.
What is General Anaesthetic Slideshare?
Introduction • General anaesthetics (GAs) are drugs which causes reversible loss of all sensation and consciousness.
How does anesthesia work pharmacology?
Local anaesthetics are drugs that block conduction of electrical impulses in excitable tissues. These tissues include the nerve cells and myocytes (both cardiac and skeletal muscles). Analgesia and anaesthesia occur as a result of the blockage of electrical impulses.
What are the stages of Anaesthesia?
There are four stages of general anesthesia, namely: analgesia – stage 1, delirium – stage 2, surgical anesthesia – stage 3 and respiratory arrest – stage 4. As the patient is increasingly affected by the anesthetic his anesthesia is said to become ‘deeper’.
What are the complications of anesthesia?
The following are possible complications of general anesthesia:
- Sore throat.
- Nausea and vomiting.
- Damage to teeth.
- Lacerations (cuts) to the lips, tongue, gums, throat.
- Nerve injury secondary to body positioning.
- Awareness under anesthesia.
- Anaphylaxis or allergic reaction.
- Malignant hyperthermia.
What are the 2 types of anesthesia?
What are the types of anesthesia?
- Local anesthesia: This treatment numbs a small section of the body.
- Regional anesthesia: Regional anesthesia blocks pain in a larger part of your body, such as a limb or everything below your chest.
What is the antidote for anesthesia?
Supportive treatment. There is no specific antidote for too much propofol. But it is a short-acting medication. If the blood pressure is too low, the anesthesiologist will give fluids and meds to support bp. If breathing slows or stops, we would ventilate by mask and/or insert a breathing tube to support breathing.
Why is anesthesia important?
Anesthesia is a medical treatment that prevents patients from feeling pain during surgery. It allows people to have procedures that lead to healthier and longer lives. To produce anesthesia, doctors use drugs called anesthetics. Scientists have developed a collection of anesthetic drugs with different effects.
How does anesthesia work?
General anesthesia works by interrupting nerve signals in your brain and body. It prevents your brain from processing pain and from remembering what happened during your surgery. A specially trained doctor or nurse, called an anesthesiologist, gives you general anesthesia and cares for you before, during, and after your surgery.
