intercostal nerve

Any of the eleven pairs of parallel nerves originating in the ventral rami of thoracic spinal nerves T1–T11. Each intercostal nerve runs forward, with a companion intercostal artery and vein, along the lower inner edge of its corresponding rib. It innervates the intercostal muscles and overlying skin.

However, often, to access an upper calyx during expiration, it is necessary to move more superiorly, making intercostal nerve injury more likely.
Therefore, with due attention to diverse opinions on efficacy of intercostal muscle flap for intercostal nerve preservation compared to intracostal suture only, the current study was designed to compare the intensity of post-operative pain in asymptomatic patients that underwent posterolateral thoracotomy with and without intercostal muscle flap.
Japan) also routed intercostal nerves to paralyzed areas in eight patients who sustained paraplegia at least a year before surgery (Neurol Mediochir [Tokyo] 6, 1964).
Review of Literature: Although block of the intercostal nerve is not new, interest in this technique was revived when Nunn and Salvin (1980) (10) re-examined the anatomy of the intercostal space in cadavers.
We conclude that using clonidine as an adjunct to bupivacaine for continuous paravertebral intercostal nerve block improves pain relief after thoracotomy, but hypotension and sedation are adverse effects interfering with its clinical application.
Zhang commonly reroutes one of the intercostal nerves that lead from the spinal cord around each rib to the sternum, If the intercostal nerve is not long enough to reach the target nerve site below the injury level, a segment of the sural nerve (isolated from the calf) is attached to the intercostal nerve.
As the pain after thoracotomy is 'neurogenic' due to damaged intercostal nerves and central hyperexcitability, known to be poorly sensitive to opioids and reliance on these drugs has detrimental effects as respiratory depression, hypoxia and long term drug dependence.
Zhang rerouted an intercostal nerve from one side of Huocheng's body to the lumbar nerve roots and, in turn, an intercostal nerve from the opposite side of his body to the sacral nerve roots.
INTRODUCTION: Normally the undivided lateral cutaneous branch of second intercostal nerve leaves the second intercostal space by piercing the lateral thoracic wall at midaxillary plane, passes along the base of axilla within the central group of axillary lymph nodes, reaches the upper and medial part of arm where it joins with medial cutaneous nerve of arm to form intercostobrachial nerve to supply the skin of upper and medial parts of arm.
Intercostal nerve block was given by the surgeon at the end of surgery for post operative analgesia and later on maintained with drugs like fentanyl, tramadol and paracetomol IV.
The sympathetic chain lies in the same fascial plane, just anterior to the intercostal nerve and communicates with it via the rami communicants
Its normal innervation is the intercostal nerves ranging from T1 to T4 or T5.
