The very first anesthesiain history was herbal remedy and was administered in time of prehistory. Somedata record mentioned the opium capsule in 4200 BC, while the same datamentioned opium poppies farmed in Sumerian at the same time as some otherancient empires mention their own records about it. The use of opiumpreparations in anesthesia was mentioned in the Embers Papyrus from 1500 BC.
By 1100 BC opium poppieswere used in Cyprus by methods similar to those today, through apparatus forsmoking of opium is similar to those in Minoan Temples, then in India and Chinain 330 BC and 600–1200 AD, although those nations used more cannabis incense.In 3rd century B.C Indian text argued about use of wine with cannabis for anesthesia.
All anesthesias havesome degree of risk, and most side effects of anesthesia are not too common.The risks involved here depend of patient’s health and (what) anesthesia isused. In case of oversensitivity, local anesthesia in proper dosage would beperfectly safe.
However, higher dosageof local anesthetics may include toxic effects, because anesthesia gets to beabsorbed via bloodstream, aka systemic toxicity. A certain level of toxicitymay be bad for blood pressure, heartbeat, breathing, maybe some other bodyfunctions.
There is also a regionalanesthesia that gets injected nearby group of nerves or near spinal cord.Damage of nerves may cause weakness, pain or simple a numbing sensation.Regional anesthesia includes spinal anesthesia, regional nerve blocks andepidural. The general risk of regional anesthesia is risk of systemic toxicity,because the anesthetic gets to be adsorbed through bloodstream. Thecomplications of regional anesthesia are:swellingproblems with lung
Spinal anesthesia however,enters the cerebrospinal fluid, around the spinal cord. The complication hereinvolves a headache because of the fluid leak. And blood patch treat spinalheadache. It is amount of blood (that belongs to patient) that gets to beinjected to fill empty space where the leak occurs and enhance pressure inspinal cord.
Also, there is a generalanesthesia and is perfectly safe for people who are healthy in general and inmost cases side effects are really minor. General anesthesia pushes reflexes ofthroat, stops aspiration and numbs gagging, swallowing, coughing etc...
In case of complicationsdue to general anesthesia, insertion of airways may lead to higher bloodpressure, or a higher heart rate, also sore throat, swelling in the larynx,irritation of the larynx, damage of teeth or lips etc. Other general anesthesiarisks may be changes in blood pressure or heart rate and may evoke heartattack.
All kind of anestheticmedicines can evoke minor abnormal reactions or allergic reactions; this is whythe consultation with surgeon before the operation is very important.
There is one verydangerous condition that may be caused by general anesthesia. It is calledmalignant hyperthermia (MH), the muscle relaxant succinylcholine, by verypowerful anesthetics for inhalation.
You may need to checkinformation listed at site of Malignant Hyperthermia Association of the UnitedStates (MHAUS) and inform yourself about potential risk.
