BIRTH INJURY
HEAD:
 Superficial:
 abrasions, bruises from forceps, scalp clip lesions, etc are usually not serious
 Cephalhematoma:
 a subperiosteal collection of blood, limited by the sutures to a cranial bone (usually parietal. Usually reabsorbed within 3 months. Leave well alone! (no treatment indicated)
 Subaponeurotic haemorrhage:
 occurs after difficult delivery or vacuum extraction and may occasionally result in extensive blood loss with shock. The head is typically swollen and oedematous making fontanelles and sutures difficult to feel. The head circumference may be increased. Anaemia and jaundice are likely to occur.
 Skull fracture: linear or depressed.
 Usually asymptomatic though occasionally associated with brain damage. Depressed fractures should be elevated surgically.
 Intracranial bleeding:
 subarachnoid or subdural (periventricular haemorrhage is usually due to hypoxia rather than trauma). Clinical features may include full fontanelle, splayed sutures, marked drop in PCV, irritability, hypotonia with poor suck, hypertonia, vomiting, apnoea and convulsions.
Diagnosis may be confirmed by finding blood in CSF at lumbar puncture or with the aid of ultrasound scanning or computerized tomography.
Management:
Nurse in incubator, feed with nasogastric tube if necessary, anticonvulsants, and dexamethasone if cerebral oedema suspected. Subdural haematoma may need to be drained surgically.
NERVE INJURIES:
 Brachial plexus:
 Erb's palsy (arm extended and pronated). Most recover fully. Refer for surgery if no improvement by 1 month.
 Facial nerve palsy:
 due to pressure by sacral promontory or secondary to forceps delivery. Weakness of upper and lower face accentuated during crying. Spontaneous recovery within a few days is the rule.
FRACTURES OF LONGBONES:
 Clavicle:
 often missed and causes few symptoms. Heals spontaneously
 Humerus and Femur:
 bruising, swelling, immobility and crepitus. Natural repair occurs with eventual return to normal shape in spite of severe displacement. Humerus should be immobilized by strapping arm to side.
 Femur:
 splint in a Gallows frame.

PERIVENTRICULAR HEMORRHAGE
Haemorrhage in the germinal matrix at the level of the caudate nucleus or the hypothalamus is common in VLBW infants (incidence ± 45%). The sub-ependyma is rich in blood vessels but poor in supporting tissue. The bleeding may then extend into the ventricles and subarachnoid space.
Many factors such as hypoxia, fluctuation in blood pressure and cerebral blood flow, venous congestion and hyperosmolarity can precipitate bleeding. Most bleeds occur in the first 72 hours of life.
Clinical signs:
 onset may be insidious or rapid
 vary from asymptomatic bleed to death
 apathy and loss of activity
 picture of shock with loss of neuromuscular tone and apnoea
 coma and death
Investigations may demonstrate:
 haemorrhage on ultrasound scan
 falling PCV or Hb
 marked metabolic acidosis
 hyperglycaemia
 hyperbilirubinaemia
The ultrasound scan is the best method of diagnosing periventricular bleeds and is often the only way that small bleeds are diagnosed. Periventricular haemorrhage is graded according to the extent of the bleeding seen on scanning. The bleed may into the germinal matrix only (grade I), extend into the ventricles (grade II), distend the ventricles with blood clot (grade III) or extend into the brain (grade IV).
Management:
 prevention may be possible by eliminating precipitating factors
 small bleeds (grade I and II) have a good prognosis and need no treatment
 large bleeds (with ventricular dilatation and hydrocephalus) need shunting.
Outcome:
The outcome depends on the grade of the bleed. The neurological development after small haemorrhages (grade I and II) seems to be no worse than for infants of comparable gestation. Extensive haemorrhages (grade III and IV) have a high mortality and morbidity as they are commonly associated with ischaemic brain damage. Brain necrosis resulting in leucomalacia and porencephaly often accompanies severe periventricular haemorrhage. Blood clots in the ventricles may cause obstructive hydrocephalus.
