hello guys,..!
i have not yet been post a lot here, because im so busy this day,but you know i have just something to tell about this topic... 

INCREASE INTRA CRANIAL PRESSURE
      Do you know what is this? I will just take an outline out of the books that I've read...
      Increase Intracranial pressure is due to increase in 1 intracranial components.
     Some Predisposing factors are:
  • head injury,tumor,localized abscess
  • hemmorhage,cerebral edema, hydrocephalus,
  • inflammatory conditions like meningitis and encephalitis
   Signs and symptoms are
   a,)change or decrease LOC- it may be restlessness to confusion  
                                              -disorientation to lethargy and stupor to coma.

   b.)Headache- patient can experienced projectile vomitting
                       -Papilledima(edema of optic disk- outer surface of retina.)
                      
   c.)Uncal Herniation-unilatateral dilation of pupil.
       Tentorial herniation-bilateral dilation of pupil
   d.)Possible seizure

GUYS you need to bear in mind that CHANGE IN VITAL SIGNS of the patient is always the LATE SYMPTOMS OF ICP.
  • Increased BP-systolic increase, diastole is same
  • Decrease HR-
  • Decrease RR-you can observe CHEYNE STOKES-between period of apnea or hyperapnea with periods of apnea.
  • Increase Temperature
NURSING PRIORITY
A..Maintain patent airway and adequate ventilation.
  1. Prevention of hypoxia-(there is decrease tissue oxygenation) and hypercarbia( there is increase in CO2 retention).
  • Late symptoms of hypoxia...B-bradycardia                 Early symptoms ...R- restlessness                                                            E-extreme restlessness                                   A-agitatation                                                                D-dyspnea                                                     T- tachycardia

 B..Assist mechanical ventilation.
  • maintain patent airway
  • monitot v/s and i and o
  • elevate head of bed 30-45 degrees, neck in neutral position unless contraindicated to promote venous drainage
  • limit fluid intake 1200-1500ml/day
  • prevents complication of immobility

C..Prevent increase of icp by:
  • maintain quite and comfort environment
  • avoid use of restraint because it can lead to fracture
  • always siderails up
  • instruct patient to avoid the ff:- Valsalva maneuver or bearing down, avoid straining of stool.-give       laxative or stool softener
  •                                             -Excessive cough,excessive vomiting and  lifting heavy objects
D. Administered meds ordered.
