Weakness of the limbs and respiratory muscles has increasingly been found to be a frequent event that complicates the medical history of patients in Intensive Care. The problem normally affects more serious cases and presents as muscular weakness leading to flaccid paralysis and difficulty in weaning patients off mechanical ventilation.

Effects of eugenol on rat phrenic nerve and phrenic nerve-diaphragm preparations
Archives of Oral Biology, 1984The compound-action potential (cAP) of the nerve evoked at 1 Hz was reversibly inhibited and the threshold for nerve stimulation increased between 0.065 and 0.97 mM eugenol. The inhibition showed a sigmoid log10 dose-response relationship. With 2.44 mM or higher concentrations the block became irreversible.

Intrathoracic Phrenic Nerve Neurofibroma
The Annals of Thoracic Surgery, 2011The usual location of intrathoracic neurogenic tumors is the posterior mediastinum. Those in a mediastinal anterior or middle location arise from the intrathoracic phrenic nerve, which is extremely rare and causes a problem for etiologic diagnosis. We report what is, to our knowledge, the second case of a mediastinal neurofibroma originating from the ...

Phrenic nerve conduction studies
Muscle & Nerve, 1992AbstractTo refine in the technique of phrenic nerve conduction, we first studied electrode positioning and sources of chest wall artifact. Diaphragmatic compound motor action potentials (DCMAPs) were mapped at close intervals over 4 hemithoraces of two subjects, finding optimum recording sites which were then used to quantitate artifacts due to EKG ...

CT Demonstration of the Phrenic Nerve
Journal of Computer Assisted Tomography, 1983Twenty-four consecutive patients examined with whole lung computed tomography (CT) using a high resolution scanner were evaluated for detection of the phrenic nerve. The phrenic nerve was considered to be demonstrable when a 1-3 mm rounded structure was identified adjacent to the pericardium on at least two contiguous sections.

Phrenic Nerve Conduction in Children
Developmental Medicine & Child Neurology, 1981SUMMARYA study was undertaken in order to establish the normal range of phrenic nerve latencies in children, to determine whether phrenic nerve stimulation can distinguish diaphragmatic palsy from eventration of the diaphragm, and to determine the effect of neuromuscular disorders on phrenic nerve latencies in children.Ninety‐four children were ...

Phrenic Nerve Function after Pneumonectomy
Chest, 1982Using surface electrodes over the lower chest wall, we measured the phrenic nerve conduction time, ie, the time interval between the stimulation of the phrenic nerve in the neck and the onset of the diaphragmatic muscle action potential, in ten patients who had undergone pneumonectomy several years before (mean, eight years) and in 31 control subjects (

Neurogenic tumour of the phrenic nerve
British Journal of Tuberculosis and Diseases of the Chest, 1958Summary A case of neurolemmoma of the right phrenic nerve is reported. The literature relating to this condition is briefly reviewed and the diagnosis and treatment is discussed.
