Streptozotocin induced diabetes as a model of phrenic nerve
neuropathy in rats.
Both pleural spaces were entered to optimize the visualization of the right and left phrenic nerves
. To prevent damage to phrenic nerves
, the entire anterior pericardium was decorticated within 2-3 cm of the phrenic nerves
, and then completed the dissection of the pericardium from the diaphragm.
Because the phrenic nerve
lies close to the IMA, it was also suggested that removing the IMA could traumatize the nerve and interfere with breathing, causing patients to become reliant on mechanical ventilation.
In recent correspondence to the journal (1), Dr Price quoted an incidence of 3% for phrenic nerve
paresis with the axillary tunnel block (2).
(A) The accessory nerve arising from a cranial nerve (i.e., emanating from the brain and not the spinal cord) is connected to the paralysis-affected phrenic nerve
(produces diaphragm contractions), restoring some respiration.
Effects of eugenol on rat phrenic nerve
and phrenic nerve
When something irritates the phrenic nerve
(that controls the movement of the diaphragm), the diaphragm contracts quickly.
The reflex arc of the hiccup has 3 components: the afferent limb composed of phrenic, vagus, and sympathetic nerves; a central processor in the midbrain; and the efferent limb composed of the phrenic nerve
supplying the diaphragm and intercostal nerves supplying the intercostal muscle fibers .
These include phrenic nerve
palsies, Horner's syndrome and recurrent laryngeal nerve palsies.
Nerve to inferior belly Superficial to subclavian (2000) of omohyoid, accessory vessels and brachial phrenic nerve
(in 1 plexus case), nerve to subclavius Akita et al.
Thymic carcinomas are larger tumors, and the findings of invasion of the great vessels, lymphadenopathy, phrenic nerve
palsy, and lung or distant metastases are seen only in patients with thymic carcinoma.
And, of course, none experienced phrenic nerve
Inhibition by local anesthetic drugs at low and high stimulation frequencies: comparison between the isolated phrenic nerve
of rat and the phrenic nerve-diaphragm preparation.
The reflex arc(2) for hiccups comprises: (1) the afferent limb: phrenic nerve
, vagus nerve, or thoracic sympathetic fibers; (2) the central connection: not a specific center, more an interaction among brain stem respiratory system, phrenic nerve
nuclei, reticular formation, and hypothalamus; and (3) the efferent limb: primarily the phrenic nerve
