Document Summary
Principles of surgical anesthesia: describe the broad types of anesthesia, review of the history of anesthesia. Amputation: strap person down in an upright position and do it without warning. General anesthesia: a drug induced loss of consciousness. Loses a lot of protective reflexes (e. g. breathing) Neuraxial anesthesia: small amount of local freezing in the back. Freezing into the spinal cord (inside or outside the dura: very dense neural block. Local anesthesia: instead of a specific nerve, we infiltrate the area (e. g. around a bump) Ether: makes people puke, diethyl ether is one of the first inhalation anesthetics. Muscle relaxants: powerful medications that cause muscle paralysis (awake but not able to breathe, not the same as muscles relaxants found in the pharmacies, exceedingly dangerous drugs, combined with volatile and neuromuscular blocking agent. Stays bound to receptor longer prolong depolarization (acetylcholine stays for short: end up with short-term paralysis (~10 min)
