In some instances, the patient is asked to choose between general and local anesthetic. There are a number of reasons why general anesthesia may be chosen over local anesthesia. The adverse effects that may be associated with general anesthesia are avoided with sedation, as the recovery period from sedation is typically quicker. On the other hand, general anesthesia usually impairs breathing, and monitoring and breathing assistance are required. However, this does not mean that respiratory assistance may not be used in some instances with sedation. Whereas, when people are under general anesthesia, they have a complete loss of consciousness.Ĭardiovascular function is usually maintained throughout sedation, and people are able to breathe independently. Sedation is generally characterized by people feeling drowsy but being in a relaxed state of consciousness. Sedation and general anesthesia are both forms of anesthesia, but people will experience different effects depending on the type administered by doctors during a procedure, including the level of consciousness, breathing support, and possible side effects. Deep: Similar to general anesthesia, as a patient is in a deep sleep.Moderate: A person may be sleepy but can wake up.Mild: A person is awake and responsive.There are three types of sedation, including: General anesthesia is also used for more lifesaving procedures such as heart surgeries or treatments for cancer, although it does carry some risks. procedures using a scope, such as a colonoscopy.minor surgeries or repairs, such as fractured bones.Medical teams may administer IV sedation for the following procedures: The following are considered to be potential risk factors: Most often, the awareness is short-lived, and a person is only aware of vague sensory experiences such as sounds, touches, or movements.Īs unintended intraoperative awareness is so infrequent, it is not clear exactly why it occurs. Patients who experience unintended intraoperative awareness can suffer long-term psychological problems. Unintended intraoperative awareness is incredibly rare, affecting an estimated 1 in every 19,000 patients undergoing general anesthesia.īecause of the muscle relaxants given alongside anesthesia, patients are unable to signal to their surgeon or anesthetist that they are still aware of what is happening. Some patients are conscious of the procedure itself, and some can even feel pain. This refers to rare cases in which patients report a state of awareness during an operation, after the point at which the anesthetic should have removed all sensation. medications that can increase bleeding - aspirin, for exampleĭeath as a result of general anesthetic does occur, but only very rarely - roughly 1 in every 100,000.existing heart, kidney, or lung conditions.obstructive sleep apnea, a condition in which individuals stop breathing while asleep.Some specific conditions increase the risk to the patient undergoing general anesthetic, such as: However, older adults and those undergoing lengthy procedures are most at risk of negative outcomes. The surgical procedure itself offers the most risk. Even particularly ill patients can be safely anesthetized. Overall, general anesthesia is very safe.
