The median nerve arises from the brachial plexus, which exits the spine between the 6th cervical and 1st thoracic vertebrae (C6 – Th1). The nerve is classified as part of the peripheral nervous system and motor and sensory enervates part of the muscles of the forearm and hand, including fingers. What is the median nerve? … Median Nerve: Structure, Function & Diseases
Classic nerve block refers to the impairment, or complete block, of peripheral nerves in their function as conductors of motor, sensory, and autonomic impulses. Permanent or facultative impairment of nerves can be triggered by mechanical pressure or traction stimuli or by chemical stimuli and, depending on the severity of the lesion, results in constant pain … Nerve Block: Causes, Symptoms & Treatment
Definition The task of peripheral nerves is to transmit information such as pain information from the body to the brain, where it is switched and processed. Furthermore, the brain and spinal cord transmit their commands, for example to move muscles, via the same nerves to the corresponding target organ. In the case of nerve blockage, … Peripheral nerve blocks
Side effects The nerves are anaesthetized using a local anaesthetic. As a result, in very rare cases of allergies to the drugs used, intolerance reactions can occur, which in the worst case end in circulatory shock. This can be partly counteracted by informing the doctor before treatment about known allergies. After the end of the … Side effects | Peripheral nerve blocks
Complications The possible side effects of femoral block are those of peripheral regional anesthesia: Nerve damage due to injuries with the cannula Nerve damage due to toxic effects of local anesthetics Bruise ( bruise ) Cardiovascular complaints (low blood pressure, circulatory arrest, etc. ) Complaints with the central nervous system (seizures, disturbances of consciousness) All … Complications | Peripheral nerve blocks
General information Local anesthesia is the temporary elimination of local nerve transmission in the body, especially pain perception. This is a local anesthesia. It is mainly used for smaller and uncomplicated operations. The local anaesthetic differs significantly from anaesthetics such as morphine because it has neither a euphoric nor an addictive effect. Local anaesthetics achieve … Local anesthetic
Mode of action Local anesthetics prevent information from being transmitted from its site of action to the brain or spinal cord. This means that pain is produced locally, but cannot be perceived by the brain. This is caused by an indirect blockage of the superficial nerves, or rather the outer membrane of the nerve fiber … Mode of action | Local anesthetic
Variants Surface anaesthesia is the lightest form of anaesthesia and acts on the fine, sensitive nerve endings of the skin. In the context of minor procedures and punctures, e.g. in the skin or oral cavity, ointments, gels, sprays or powders reduce the perception of pain.For example, the dentist can coat the oral mucosa with an … Variants | Local anesthetic
Side effects In general, the side effects of local anesthetics are considered very low compared to the side effects of general anesthesia. Nevertheless, it is important to mention that local anesthetics are derived from cocaine and therefore have a certain (albeit minimal) addictive potential on the one hand, and may have certain side effects on … Side effects | Local anesthetic
Spinal shock is defined as a condition that occurs after a spinal cord lesion with partial or complete severance of the nerve tracts in the parts of the body below the site of the lesion, such that even external and intrinsic reflexes are completely shut down. The skeletal musculature and also the visceromotor autonomic musculature … Spinal Shock: Causes, Symptoms & Treatment
