The fourth intercostal nerve is innervated by cutaneous slowly-adapting and rapidly-adapting mechanoreceptors, especially by ones densely-packed under the areola; innervation subsequently triggers oxytocin release, which, when in the peripheral bloodstream, causes myoepithelial cell contraction and lactation: this is an example of a non-nerve ...
Intercostal nerve block (abbreviated ICNB) is a nerve block which temporarily or permanently interrupts the flow of signals along an intercostal nerve, usually performed to relieve pain. [ 1 ] Uses
The block can be extended by placing an indwelling catheter, which may be connected to a mechanical or electronic infusion pump for continuous administration of local anesthetic solution. A catheter may be inserted at the interscalene, supraclavicular, infraclavicular or axillary location, depending on the desired location of nerve block.
These rami are called the intercostal nerves. In regions other than the thoracic, ventral rami converge with each other to form networks of nerves called nerve plexuses. Within each plexus, fibers from the various ventral rami branch and become redistributed so that each nerve exiting the plexus has fibers from several different spinal nerves.
The anterior rami will follow the course of the rib - T1 will contribute to the brachial plexus & a smaller branch will form the first intercostal nerve - T2 and sometimes T1 contributes to the intercostobrachial nerve Each intercostal nerve gives off a lateral cutaneous branch which divides into an anterior branch and a posterior branch which ...
Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.

[2] [3] It can also be used for applying a nerve block known as the rhomboid intercostal block, which can be used to relieve pain after rib fractures, and a thoracotomy. This nerve block is usually achieved by injection of the local anesthetic agent into the fascial plane between the rhomboid upper intercostal muscle and the rhombic muscles. [4 ...
