        -     Muscles of the chest, abdominal wall,
       diaphragm, urinary bladder and bowel can be                       Complication:
       affected constipation or stool incontinent and                      Emotional disturbance.
       urinary incontinent may occur.                                      Gastric dilatation.
                                                                           Hypertension.
        Bulbar: More life threatening. It causes damage to
      cranial nerve nuclei, vital centers of respiration,
      circulation and temperature control.

        -     It may leads to swallowing problem and
       regurgitation of fluids from nose and inability to
       swallow saliva, which puddles in the pharynx. If not
       aspirated chocking may occur.

        Encephalitis: Manifesting as encephalitis, only
      diagnosed as polioencephalitis if spinal or bulbar
      affections or both are present:

        -    Convulsion.

        -    Personality disturbances.

Nursing Considerations:
 1. Isolation and bed rest.
 2. In acute stage:
         Put the child under close observation.
         Notify the doctor about the degree and progress of
       the paralysis (7or8 days of the disease).
         Rate and type of respiration and signs of
       respiratory distress must be observed and reported.
         Oxygen therapy or place the child on respirator
       when cyanosis occurs.
         If tracheostomy is done in case of diaphragmatic
       paralysis, care of tracheostomy.

 3.    For paralysis:
           Change position frequently. Careful positioning
         for affected limbs each time he is turned or moved.
           To minimize the degree of deformity, correct
         body alignment and optimum position must be
         maintained.
           Place the child on firm mattress.
           Use footboard to prevent foot drop when child is
         on back. If the child is on abdomen, pull the
         mattress away from foot of bed and letting feet
         protrude over the edge to prevent pressure on toes.
           Application of heat to affected muscles to relax
         them.

 4.    Suction of the pharynx and postural
       drainage to prevent aspiration of secretions.
 5.    For swallowing difficulties:
           Soft diet if they can swallow with difficulty.
           If swallowing is difficult, use gavage feeding.
 6.    For incontinent:
           Skin care and perineal region is padded to
         provide absorption for excretions. Catheter may be
         done.
 7.    For constipation: Use enemas.
 8.    Treat fever and headache.

Treatment:
    Symptomatic.
   Physiotherapy.

Prevention:
Active immunization: Trivalent poliovirus vaccine.
(TOPV).
      Sabine: Attenuated virus, which is administered
    orally.
      Salk: Killed virus, which is administered by
    injection.

Note: If a child is affected by poliomyelitis, he must receive the
vaccine to prevent further infection from the other poliovirus
types.
