Anesthesia is the use of drugs to prevent pain during medical procedures. The drugs used to anesthetize a patient are called anesthetics. Anesthesia is carried out in several medical operations including ambulatory surgeries, gastroenterology practices and interventional pain management practices.
Anesthetics work by affecting the nervous system to cause numbness or memory loss leading to unconsciousness. The first known anesthetics were bitter herbs and alcohol that were used for minor operations. There is a wide variety of anesthetics both different from each other on the basis of their action. The different types of anesthetics include sedatives, neuromuscular-blocking drugs, hypnotics and an array of other nervous system stimulants or depressants. A patient can be anesthetized with either the intention of causing unconsciousness or loss of sensation.
Local anesthesia is where the patient is anesthetized with the intention of causing muscle paralysis in the part of interest such as limbs. The effects of local anesthesia are reversible and the patient is conscious unless the anesthesia is combined with other anesthesia approaches including sedation. Sedation is a type of anesthesia whereby anesthetics are used to suppress the central nervous system mildly by reducing anxiety. It is frequently used in minor procedures such as in dentistry operations and the patient is conscious. Anesthesia that causes unconsciousness of the entire body is known as general anesthesia. General anesthesia acts on the central nervous system causing loss of reflexes. General anesthesia causes total loss of sensation and is particularly applied in major medical operations including reconstructive surgery.
Anesthesia services can be used to mitigate both minor and major medical surgeries. This can be done through the use of a dose of a single anesthetic or a dose of two or more anesthetics. However, anesthesia is highly delicate and requires a lot of precaution from the administering medic. Before anesthesia is carried out, the doctor must conduct a check on the patient’s medical history. This is because some genetic disorders and lifestyle habits might impact the anesthetic. The doctor should also carry out a physical examination on the patient as well as laboratory tests to reduce chances of anesthesia risks to the patient. Therefore, the doctor will select the type of anesthetic not only depending on the level recommended to bring the patient to a required state before the operation, but also how the anesthetic will react with the patient.
Anesthesia service not only include the act of administering anesthetics to patients before operations but also applying anesthetics to post-operation patients experiencing pain. These services also seek to help patients that have undergone anesthesia to recover.
There are medical facilities that work purposefully to give solutions to patients seeking anesthesia services. Most of these anesthesia dedicated centers work side by side with other hospitals. The doctors can recommend a patient with simple health conditions that are not necessarily linked to a fore lying problem to these facilities. The most common practices of these centers include interventional pain management which seeks to suppress extreme pain or discomfort
