Page 26: 2011 Neuro1

DAY 1 IN PICU

• Child was noted to have ICP of 42 at 30 min of the time of insertion…….

• What are the things to be looked for?

Page 27: 2011 Neuro1

O/E• Vitals– HR = 92/min– RR = 50 /min– BP = 130/84 mm Hg–Moving limbs on sound and touch– EEG = no seizure activity– Temp = 36.60 C –Whats your interpretation?

Page 28: 2011 Neuro1

• Cause: Improper sedation 2 Marks

Page 29: 2011 Neuro1

• What is your sedation and paralysis strategy in this child?

Page 30: 2011 Neuro1

How will you optimize the Nursing care?

Page 31: 2011 Neuro1

AT 6 HRS OF PICU ADMISSION

• ICP = 36 mm Hg• Vitals– HR = 136/min– RR = 40 /min– BP = 130/80 mm Hg– Moving limbs only to deep pain– Temp = 39.80 C – EEG = no seizure activity

•What is the likely precipitating factor for rise in ICP?

Page 32: 2011 Neuro1

ON DAY 2 OF PICU• ICP = 40 mm Hg• Vitals– HR = 130/min– RR = 46 /min– BP = 130/80 mm Hg– Temp = 36.60 C– Tonic deviation of eyes to the left side

•What is the likely precipitating factor for rise in ICP now? How will you manage it?

Page 33: 2011 Neuro1

Day 3 of PICU

– ICP of 30 mmHg– CVP = 4 cm– BP = 70/ 36 mm Hg (MAP = 50 mm Hg)– What s the cause?– How will you manage?

Page 34: 2011 Neuro1

• BP = 78/45 mm Hg ( MAP = 55 mmHg)

• CVP is 12• ICP =26 mm Hg ( CPP =24mmHg)• WHAT IS YOUR NEXT STEP?

Page 35: 2011 Neuro1

• Choice of Inotrope?

Page 36: 2011 Neuro1

Role of therapeutic Hypothermia

Page 37: 2011 Neuro1

Role of Decompressive craniotomy?

• 1- isType B waves have an amplitude of upto 50mmHg. and a duration of <2 minutes. They also reflect reduced intracranial compliance, but are a less sinister finding than A waves.

• 2 Marks

• 2- Type A (plateau waves) are largest in amplitude (50-100mmHg above baseline ICP) and duration (5-20 minutes). They are thought to be due to cerebral

• vasodilatation in response to critically low cerebral perfusion. This dilatation further raises ICP, compromising cerebral perfusion and increasing the risk of brain herniation.

• 2 Marks

• Lundberg waves occur over a period of time and should not be confused with the three peaks of thenormal intracranial pressure waveform seen in normal individuals andrelated to the arterial waveform.

Page 43: 2011 Neuro1

DAY 5 OF PICU

• ICP showed no rise even on stimulation and suctioning and spontaneous movements.

• WHAT NEXT?

Page 44: 2011 Neuro1

• STOP SEDATION AND CONSIDER EXTUBATION

• ICP monitoring was discontinued with removal of ICP catheter…

• 2 MARKS

1) At 6 hours:

• Low BP alarm starts ringing• Five minutes later low SpO2 alarm

also starts ringing

Page 47: 2011 Neuro1

BP fell to 86/50 Tachycardia increased to 162 min Pupils- R dilated and fixed

L mid size, sluggish reaction

Page 48: 2011 Neuro1

• What could be the cause for these neurological and hemodynamic changes

Page 49: 2011 Neuro1

How will you give the prognosis?

• low GCS was most associated with poor outcome• The absence of pupil reactivity is a predictor of

poor outcome.• Radiographically, obliteration of the third

ventricle and midline shift was most likely to be associated with early mortality (14 days), and

• nonevacuated hematoma was most likely to be associated with poor outcome at 6 months.

• Days 3 Child develops severe polyuriaSerum Na+ = 163 meq/LSerum osmolality = 336Urinary Na+ = 8 meq/LUrinary specific gravity = 1002

Page 51: 2011 Neuro1

• What is the cause of this polyuria.

Page 52: 2011 Neuro1

• Day 4 Patient develops fever – 390 C

Page 53: 2011 Neuro1

• What are the common causes of fever in this situation
