A local anesthetic is a drug that causes reversible local anesthesia and a loss of nociception. When it is used on specific nerve pathways (nerve block), effects such as analgesia (loss of pain sensation) and paralysis (loss of muscle power) can be achieved. Clinical local anesthetics belong to one of two classes: aminoamide and aminoester ...
Intrathecal administration is often used for a single 24-hour dose of analgesia (opioid with local anesthetic). Caution should be exercised with intrathecal opioids due to the risk of late onset hypoventilation. The use of intrathecal morphine may be limited by severe pruritus and urinary retention.

Many local anesthetics fall into two general chemical classes, amino esters (top) and amino amides (bottom). A local anesthetic (LA) is a medication that causes absence of all sensation (including pain) in a specific body part without loss of consciousness, [1] providing local anesthesia, as opposed to a general anesthetic, which eliminates all sensation in the entire body and causes ...
A scavenger system is a medical device used in hospitals. It is used to gather anaesthetic gases , after it is exhaled from the patient or left the area of the patient, and transport it to the atmosphere, skipping the closed environment of the operating room. [ 1 ]
An anesthetic vaporizer (American English) or anaesthetic vapouriser (British English) is a device generally attached to an anesthetic machine which delivers a given concentration of a volatile anesthetic agent. It works by controlling the vaporization of anesthetic agents from liquid, and then accurately controlling the concentration in which ...
General anesthesia does not always require the anesthetic machine, tested daily, as basic equipment. Anesthesia machines may differ in appearance, size and degree of sophistication but generally speaking, they consist of sections for: ventilation; Peripheral Nerve Stimulator; space for monitoring equipment; accessories; storage space; worktop
This may be characterized by serious central nervous system problems such as epileptic seizure, central nervous system depression, and coma. [16] Cardiovascular effects of local anesthetic toxicity include slowing of the heart rate and impairment of its ability to pump blood through the circulatory system, which may lead to circulatory collapse.
