“Risk Factors For Developing Peripheral Nerve Injuries”

Peripheral Nerve Etiology

• Traumatic: Either closed or open injury
• Inflammatory: Leprosy, diphtheria, herpes zoster
• Lead and arsenical poisoning
• Alcoholism
• Diabetes mellitus
• Vitamin B1 deficiency
• Porphyria
• Neurofibroma and other neural tumors
• Idiopathic.

Peripheral Nerve Clinical Features

• Loss of sensory, motor, autonomous and reflx functions.
• Secondary changes in the skin and joint.

Management Of Peripheral Nerve Injury

Peripheral Nerve Medicinal

• Steroids: They reduce the edema around nerve and is useful in neurapraxia. Prednisolone 5 to 10 mg is effctive.
• Nerve tonics: Vitamin B
  1, B6, B12, they are supposed to facilitate nerve fier regeneration and are useful in cases of neuropraxia and axonotmesis.
• In cases with acute neuralgic pain, drugs like carbamazepine or gabapentin can be prescribed. It is purely symptomatic treatment.
• Physiotherapy: Inthe form of electrical nerve stimulation (TENS) and in cases of motor nerve exercises and massage therapy can be given.

Causes Of Peripheral Nerve Injury

Peripheral Nerve Surgical

• Decompression: It is used if nerve compression occurs resulting into neuropraxia.
  It is usually done when nerve due to bone deposition in the nerve canal; there is pressure on the nerve leading to neuropraxia. Here,enlargement of the canal boundaries is done to relieve the pressure on the nerve.
• Anastomosis: It is microsurgical repair of the severed ends of the nerve. It is useful, when there is no loss of nerve tissue as in accidental clean surgical by transection of the nerve.
• Cross innervation: It is useful when there is motor nerve defiit due to a lesion in the course of the nerve.
  In this repair, a nerve is grafted to connect the affcted nerve to the normal functional nerve on the other side of the body using microsurgical repair.

Symptoms Of Peripheral Nerve Injury

“Tests For Diagnosing Peripheral Nerve Damage”

• Nerve grafts: It is use of a nerve segment from one part of the body to reconstruct and repair an affcted nerve in some other part using microsurgical technique.
• Glasgow coma scale gives clear idea about neuronal injury.
• Autonomic disturbances with bradycardia, systolic hypertension, deep and slow respiration, Cheyne stokes ventilation.
• Cushing’s triad of raised intracranial pressure is obvious i.e. bradycardia, hypertension and respiratory irregularity.
• Features such as restlessness, irritability, headache,vomiting and progressive deterioration are common.
