neonatal brachial plexus palsy

Introduction

Introduction to neonatal brachial plexus paralysis Neonatal birth injury refers to damage to the fetus or newborn caused by mechanical factors during childbirth. In recent years, due to the strengthening of prenatal examination and the improvement of obstetric techniques, the incidence of birth injury has decreased significantly, but it is still one of the causes of neonatal death and long-term disability, especially in grassroots units. Brachial plexus paralysis is the most common type of neonatal peripheral nerve injury. Due to dystocia, breech presentation, difficulty in shoulder delivery and other factors, the brachial plexus is excessively pulled and damaged. Full-term, greater than gestational age children are more common. Magnetic resonance can determine the location of the lesion. Electromyography examination of the spinal nerve conduction test is also helpful for diagnosis. The prognosis depends on the degree of damage. If the injury is neurological paralysis, it can be completely recovered within a few weeks. basic knowledge The proportion of illness: 0.001% Susceptible population: newborn Mode of infection: non-infectious complication:

Cause

Neonatal brachial plexus paralysis

Due to dystocia, breech presentation, difficulty in shoulder delivery and other factors, the brachial plexus is excessively pulled and damaged. Full-term, greater than gestational age children are more common.

Prevention

Neonatal brachial plexus paralysis prevention

For the prevention of the cause, doctors should pay attention to avoid injury to the baby during production.

Complication

Neonatal brachial plexus paralysis complications Complication

Upper limb activity dysfunction.

Symptom

Neonatal brachial plexus paralysis symptoms Common symptoms Moro response slow upper limbs flaccid paralysis upper extremity abduction lifting difficulty upper limbs semi-flexive upper limbs peripheral sacral reflexes disappearing cleft palate narrow pupil abnormalities

According to the different parts of the lesion can be divided into: 1 upper arm type: also known as Duchenne-Erb paralysis, because the fifth and sixth cervical nerve roots are most vulnerable, so this type of clinical most false. The entire upper limb of the affected side is drooping, adducted, unable to abduct and rotate. The elbow joint is characterized by adduction of the forearm, straightening, non-spinning or bending. Wrist and knuckle flexion, hug reflection asymmetry. 2 middle arm type: neck 7 nerve root injury, muscle paralysis dominated by phrenic nerve, forearm, wrist, hand stretching or loss, while triceps, thumb extensor muscle is incomplete paralysis. 3 lower arm type: neck 8 to chest 1 nerve root involvement, wrist flexor and hand muscle weakness, weak grip, clinically less common, such as the first thoracic sympathetic nerve fiber damage, can cause Horner synthesis The sign is characterized by a narrowing of the pupil and a narrowing of the cleft palate.

Examine

Examination of neonatal brachial plexus paralysis

Magnetic resonance can determine the location of the lesion, and electromyography and nerve conduction experiments are also helpful for diagnosis.

Diagnosis

Diagnosis and differentiation of neonatal brachial plexus paralysis

Magnetic resonance can determine the location of the lesion. Electromyography examination of the spinal nerve conduction test is also helpful for diagnosis. The prognosis depends on the degree of damage. If the injury is neurological paralysis, it can be completely recovered within a few weeks.
