Study Notes
Types of Anesthesia
- General Anesthesia: A state of controlled unconsciousness, during which the patient is unaware of the surgery and feels no pain.
- Regional Anesthesia: Numbs only a specific part of the body, such as a limb or the lower abdomen.
- Local Anesthesia: Numbs only a small area, such as a skin lesion or a tooth.
- Sedation: A state of relaxation, during which the patient is awake but unaware of the surgery.
Mechanisms of Anesthesia
- Inhalation Anesthetics: Work by altering the activity of neurotransmitters in the brain, leading to unconsciousness.
- Intravenous Anesthetics: Work by blocking the action of neurotransmitters or by activating inhibitory receptors.
- Local Anesthetics: Block the transmission of nerve impulses, preventing pain signals from reaching the brain.
Anesthesia Methods
- Induction: The process of putting a patient under anesthesia, often using an inhalation anesthetic.
- Maintenance: The process of keeping a patient under anesthesia during surgery, often using a combination of anesthetics.
- Recovery: The process of bringing a patient out of anesthesia after surgery.
Anesthesia Risks and Complications
- Respiratory Depression: Slowed breathing rate, which can lead to respiratory failure.
- Cardiovascular Instability: Changes in blood pressure and heart rate, which can lead to cardiac complications.
- Allergic Reactions: Rare but potentially life-threatening reactions to anesthetic agents.
- Post-Anesthesia Care Unit (PACU) Complications: Complications that occur in the recovery room, such as nausea and vomiting.
Anesthesia Providers
- Anesthesiologists: Medical doctors who specialize in anesthesia care.
- Certified Registered Nurse Anesthetists (CRNAs): Advanced practice nurses who specialize in anesthesia care.
- Anesthesia Assistants: Assist anesthesiologists and CRNAs with anesthesia care.
