Local anesthesia is “an anesthetic drug (which can be given as a shot, spray, or ointment) numbs only a small, specific area of the body (for example, a foot, hand, or patch of skin)”(Jones). A person may be awake or sedated when given local anesthesia. This depends on the extent of what is needed during the surgery. Local anesthesia has been used for over 120 years in the United States and “an estimated 300 million anesthetic carpules are used each year”(Mayo Clinic Staff, 2013).
In 1884, William Halsted used a local injection of cocaine that was the first peripheral nerve block in medicine. While cocaine is no longer used some of Halsted’s methods are still taught in dental schools around the world today. Procaine was later used in 1904 by Alfred Einhorn and was the most successful local anesthetic. Today the drugs brand name is Novocain. The most common local anesthetic today is lidocaine, which was developed byNils Lofgren in 1948.
Today, all current used local anesthetics are synthetic. Local anesthetics are classified into two different categories according to linkage. These two categories are amide linkage and ester linkage. Almost all injectable anesthetics are amides.

...If the child is crying or will not be still in the chair, the dentists’ first thought is to put the child to sleep. This is only starting out their dental experience negative at a very young age. These children need to be worked with at a young age and shown that the dentist office is not a terrible place. They need to enjoy their experiences while they are young so they will not be apprehensive and more likely to routinely go when they are older.
Anesthesia should be avoided at all costs if possible in a dental visit. Local anesthesia seems to be the safest and easiest route when performing dental procedures that need some sort of numbing agent. If sedation must be used conscious sedation will be the safest and faster recovering procedure. The only time general anesthesia should be used is when it is absolutely necessary and no contraindications are present.

- Monitored Anesthesia Care Monitored anesthesia care (MAC) is a process whereby a patient undergoes anesthesia simultaneously with analgesia and sedation. MAC is usually considered in about 30% of all surgical procedures. There are three fundamental purposes of conscious sedation during MAC: safe sedation, pain control, and control of patient anxiety (Reich et al., 2011). Patients that undergo conscious sedation have the ability to answer instructions appropriately as well as protect their airways.... [tags: Anesthesia, Surgery, Medicine]

- Anesthesia was developed in order to block or prevent pain during medical procedures. Anesthesia has been the backbone of the medical world for around 100 years now. Early anesthetics were primitive and many patients simply did not trust anesthetics. Anesthesia is still a risky process even in todays advanced medical world. Anesthesia is not used to treat or diagnose any specific disease; the sole purpose is to aid both the patient and surgeon through procedures. However, anesthesia is used in different ways based on the magnitude of the procedure.... [tags: Medicine]

- The Necessity of the Local Food Movement Imagine that a family is unable to produce enough food for themselves because they need the money that they get for selling their products. Globalization is the cause of starvation among farmers because they earn less money. Small-scale farms are replaced by larger farms and they cannot compete with them. Local food can be defined in a lot of different ways. According to Rosylynn Brain, local food means, “minimizing the distance between production and consumption.” The local food movement eliminates the problem because food is easily accessible through small farming and the utilization of farmers’ markets....
