Partial or intraosseous general anesthesia is a type of general anesthesia in which consciousness is turned off, while other body functions are preserved. This type of anesthesia is used quite often, both for short-term purposes (for example, tooth extraction) and for major operations with long recovery periods. How exactly does intraosseous anesthesia work and what are the risks? With this anesthesia, a thin needle is inserted into the bone, rather than a chloroform-type drug being supplied either into the bloodstream or into the bone through a very thin catheter. The doctor monitors the overall intensity of the narcotic substance and quickly adjusts its dose if the need arises - he can slightly increase it if necessary.
