HYDROCEPHALUS

Introduction “Hydrocephalus is a condition in which there is excessive fluid accumulation in the brain.” The word Hydrocephalus derived from two words -hydro means water, cephalus means head

Definition:-“is a condition in which portion of the entire ventricular system is

abnormally dilated & the CSF has been under increased pressure.”

Incidence Sex

Bickers adam syndrome NPH

Age Infancy Adulthood (40%)

Mortality and morbidity Due to brain herniation and resp. arrest

Identify the etiology

Enumerate the classification

Discuss the

Classification and etiology:A. Depending on the type of block Non communicating (block is intraventricular) ¾ Mal development of the aqueduct¾ Obstruction due to mass lesions¾ Obstruction secondary to exudate , haemorrhage or paracsites¾ Obstruction of the fourth ventricle outlet foramina- dandy Walker

malformation Communicating type(block is extra ventricular)¾ Post infectious, post hemorrhagic, or developmental adhesions of

basal cisterns or surface arachnoid space¾ Commonly after neonatal meningitis or intra ventricular

haemorrhage¾ Arachnoid villi obstruction by erythrocytes, exudates¾ Skeletal defects- achondroplasia

B ) depending on the time of presentation Congenital hydrocephalus

Clinical features¾ Enlargement of the head(speed of enlargement proportional to

ICP ) & small face¾ Sunsetting eye sign¾ Separation of the sutures & ¾ widening , fullness of ant. Frontanelle¾ Prominent scalp vein¾ Wasting is common with progression of hydro cephalus¾ CRACK POT RESONANCE(Macewen sign)¾ Epileptic attack

management

Enlist the complications of shunt

¾ MRI

Management :Goals

¾ To reduce the CSF pressure ¾ To reduce irritability¾ To prevent infection¾ To improve nutrition¾ To improve the skin integrity

Medical management¾ Osmotic diuretic: cerebral edema¾ Carbonic anhydrase inhibitors: Acetazolamide¾ Antibiotics¾ Slightly elevate the head end of the bed to 15º

Stationary or arrested type¾ No surgical intervention is needed

Progressive type¾ Site of block should be localised¾ Repeated lumbar puncture¾ Use of Acetazolamine 50-75 mg/kg/day

Expanding lesion¾ Excision of the tumor¾ Ventricular tapping

Discuss the nursing management

¾ Endoscopic 3rd ventriculostomy¾ Cauterisation of the choroid plexes¾ Surgical intervention required¾ Ventriculoatrial shunt¾ Ventriculoperitoneal shunt¾ Ventriculogallbladder shunt¾ Ventriculoureteric shunt

Complications of shunt Outgrows tube length Subdural haematoma Mechanical failure Obstruction Over/ under drainage Failure of the valve Perforation Infections Collapse of the ventricular valve Other Complications like Physical injury, Delayed growth and

development and Decreased intracranial adaptive capacity

Nursing Nursing ManagementAssessment

Sunset sign Inability to support the head when upright Cracked pot

Nursing diagnosis1. Disturbance in comfort , irritability r/t disaese condition2. High risk for respiratory arrest related to increased ICP3. Risk for blockage of the shunt4. Risk for infection related to the presence of shunt5. Risk for impaired nutrition r/t poor feeding6. Risk for complication(seizures)7. Anxiety8. Knowledge deficit9. Altered parental coping

Nursing interventionDisturbance in comfort , irritability r/t disaese condition-Provide a quiet environment with less stimuli.-Advice to use zero watt bulbs to minimize photosensitivity.-Avoid too much neck flexion or manipulation.-Sit near the child and speak in a low ,modulated voice-Minimal handling of the baby is advised-Elevate head end to 300 to reduce cerebral oedema-Monitor TPR every two hourly

High risk for respiratory arrest related to increased ICP Check signs of increased ICP Assess the respiratory status Monitor vital signs every 2 hrly

Discuss the nursing management

Support the child’s head when the child is upright

Risk for blockage of the shunt Measure HC to aid in diagnosis of hydrocephalus Monitor vital signs and intake and out put Assess neurologic status Don’t allow the child to lie on the same side of shunt Instruct to lay flat to avoid rapid decompression Signs of ICP Teach parents signs of increasing ICP

Risk for infection related to the presence of shunt Observe signs of infection Provide proper skin care to the head , turn it frequently Monitor signs of infection like elevated W.B.C, E.S.R Follow strict aseptic techniques to minimize infection Maintain fluid volume through IV therapy

Risk for impaired nutrition r/t poor feeding-Maintain fluid volume through IV therapy-Give expressed breast milk-Provide ryles tube feeding-Provide soft diet to avoid too much difficulty by mastication

Risk for complication(seizures) Educate seizure precautions Administer anticonvulsants as prescribed. Raise the padded side rails of bed to prevent any falls Ensure that injurious toys and instruments are kept at a safer place.

LCD slides

Monitor the pattern of seizures Teach the parents how to use padded spoons to clench between teeth

during seizures Provide side-lying position after seizures to prevent aspiration. Avoid overcrowding during seizure episode. Administer O2 and do suction in case of status epileptics

Anxiety-provide psychological support to parents-Be with the child and speak in a low and calm voice-Ensure the safety of the child in the absence of his parents-Support family members while explaining about the child’s prognosis-Provide play articles or transitional objects to the child to avoid boredom and to make him feel comfortable

Knowledge deficit- Teach parents signs of increasing ICP-Educate the family about need calm environment-Provide them a copy of immunization protocol-Educate the need for HiB vaccine for unimmunized siblings at home-Encourage them to clarify their doubts-Teach them about the disease ,its prognosis and management

Altered parental coping provide psychological support encourage them to verbalise feelings advise about supporting agencies
