NERVE INJURIES IN NEWBORN

Nerve injuries may occur before or during delivery. These injuries usually cause weakness of the muscles controlled by the affected nerve.

 Nerve injuries may involve the

• Facial nerve: Lopsided facial expression
• Brachial plexus: Arm and/or hand weakness
• Phrenic nerve (rare): Difficulty breathing
• Spinal cord (rare): Paralysis
• Facial nerve injury is evident when the newborn cries and the face appears lopsided (asymmetric). The facial nerve is the nerve injured most often. This injury is caused by pressure against the nerve due to
• The way the fetus was positioned in the uterus before birth
• The nerve being pressed against the mother's pelvis during delivery
• Forceps used to assist the delivery

No treatment of facial nerve injury is needed, and the muscle weakness usually resolves by 2 to 3 months of age. However, sometimes facial nerve weakness is caused by a congenital disorder rather than an injury and does not resolve.

• The brachial plexus is a group of large nerves located between the neck and shoulder, leading to each arm. During a difficult delivery, one or both of the baby's arms can be stretched and injure the nerves of the brachial plexus ( see Plexus Disorders) and cause weakness or paralysis of part or all of the baby's arm and hand. Weakness of the shoulder and elbow is called Erb palsy, and weakness of the hand and wrist is called Klumpke palsy. About half of the cases of brachial plexus injuries are related to difficult deliveries, typically involving large babies, and about half occur in babies with normal deliveries. Brachial plexus injury is less frequent in babies delivered by cesarean delivery. Extreme movements at the shoulder should be avoided to allow the nerves to heal. Many milder injuries resolve over a few days. If the abnormality is more severe or lasts for more than 1 or 2 weeks, physical therapy or occupational therapy for proper positioning and gentle movement of the arm are recommended. If there is no improvement over 1 or 2 months, doctors typically recommend the baby be evaluated by a pediatric neurologist and/or orthopedist at a pediatric specialty hospital to see whether surgery may be beneficial.
• The phrenic nerve, which is the nerve going to the diaphragm (the muscular wall that separates the organs of the chest from those of the abdomen and assists in breathing), is occasionally damaged, resulting in paralysis of the diaphragm on the same side. In this case, the newborn may have difficulty breathing and sometimes requires assistance with breathing. Injury of the phrenic nerve usually resolves completely within a few weeks.
• Spinal cord injuries due to overstretching during delivery are extremely rare. These injuries can result in paralysis below the site of the injury. Damage to the spinal cord is often permanent. Some spinal cord injuries that occur high up in the neck are fatal because they prevent the newborn from breathing properly.
• Other nerves, such as the radial nerve in the arm, the sciatic nerve in the lower back, or the obturator nerve in the leg, also may be injured during delivery.

HOMOEOPATHIC TREATMENT

HYPERICUM PERFORATUM: Excessive painfulness is a guiding symptom of Hypericum. Hypericum is an effective remedy for nerve pain with tingling, burning and numbness. Hypericum is an effective remedy for nerve pain after injury to nerves, especially fingers, toes, nails. Shooting pains from the injured part. Injury to brain and spinal cord. Back pain due spinal injury.  It is best for traumatic neuralgia and neuritis.

PUSATILLA NIGRICANS: Pulsatilla is excellent for facial neuralgia, especially of right side, with a drawing or tearing sensation. They are worse from chewing, warmth and lying on painful side. The mouth feels dry, but the person does not drink. Pains are better from cold applications and open air.

SPIGELIA: Spigelia is one of the most effective medicines for facial neuralgia when pain is affected on left side. There is lightening like pains come on from morning until sunset. The pain is extending to left eye, left chest, and left shoulder. Pains are worse from stooping or moving the head, from noise, during perspiration, from cold water and air and after chewing. The person has a flushed red face on the affected side and pains come on at certain times of day.

ARSENICUM ALBUM: Arsenicum alb is another effective remedy for trigeminal neuralgia. Arsenic is prescribed where the pains feel drawing or burning in nature as if from needles. The person is anxious, restless and thirsty. Pains are ameliorated by warm applications and are aggravated by cold air, also worse after midnight.

AGARICUS: This remedy may be indicated in Bell's palsy when the facial muscles on one side are stiff, and grimacing or twitching occurs in other parts of the face. People who need this remedy are often excitable, with senses that are overacute. Many people who need this remedy have deep anxiety about their health.
