Anesthesia & Analgesia
Anesthesia
Anesthesia (pronounced: an-uh-sthee-zhuh) is a medical procedure that involves the use of drugs to block physical sensation, typically during surgery. The term originates from the Greek words "an-" meaning "without" and "-aesthesia" meaning "sensation".
Anesthesia can be divided into three main types: General anesthesia, Regional anesthesia, and Local anesthesia.
- General anesthesia is a state of total unconsciousness resulting from general anesthetic drugs.
- Regional anesthesia only affects a specific region of the body. This includes Spinal anesthesia, Epidural anesthesia, and Nerve blocks.
- Local anesthesia numbs a small, specific area of the body and is typically used for minor procedures.
Analgesia
Analgesia (pronounced: an-uhl-jee-zee-uh) is the inability to feel pain while still maintaining consciousness. The term is derived from the Greek words "an-" meaning "without" and "-algesia" meaning "pain".
Analgesia can be achieved through various methods such as Pharmacological analgesia, which includes Opioids, Non-opioid analgesics, and Adjuvant analgesics. Another method is Non-pharmacological analgesia, which includes techniques like Acupuncture, Massage, and Transcutaneous electrical nerve stimulation (TENS).
