Pupil Assessment — PERLA

PERLA Checklist

Pupils Equal and Reactive to Light, Accommodation
Assess size in mm (normal 2–5 mm)
Assess reactivity: brisk / sluggish / fixed
Asymmetry >1 mm = clinically significant
Unilateral fixed dilated pupil: CN III compression (uncal herniation)
Bilateral fixed dilated pupils: brainstem dysfunction / herniation
Bilateral pinpoint pupils: pontine lesion / opioids

Pupil Size Reference

Finding	Implication
2–5 mm, brisk bilat.	Normal
Asymmetry >1 mm	Concern — assess urgently
Unilateral fixed dilated	CN III compression
Bilateral fixed dilated	Herniation / death
Bilateral pinpoint	Pons / opioids

Cushing's Triad — Raised ICP Emergency

Cushing's Triad = Impending Herniation: Bradycardia + Hypertension (widened pulse pressure) + Irregular (Cheyne–Stokes) respirations. This is a late, pre-terminal sign — act immediately.

1. Bradycardia

HR drops as brainstem compressed — Cushing reflex

2. Hypertension

SBP rises to maintain CPP; widened pulse pressure

3. Irregular Respirations

Cheyne–Stokes, ataxic, or apnoeic breathing

Sedation Scoring — RASS

Score	Label	Description
+4	Combative	Violent, danger to staff
+3	Very Agitated	Pulls tubes, aggressive
+2	Agitated	Frequent non-purposeful movement
+1	Restless	Anxious but movements not aggressive
0	Alert & Calm	Target for most ICU patients
-1	Drowsy	Sustained eye opening to voice (≥10s)
-2	Light Sedation	Eye opening to voice briefly (<10s)
-3	Moderate Sedation	Movement to voice, no eye opening
-4	Deep Sedation	No response to voice, moves to physical stimulus
-5	Unarousable	No response to voice or physical stimulus

Target RASS for ventilated neuro patients: −1 to −2 (light sedation) unless raised ICP requiring deeper sedation. RASS −5 may be appropriate for barbiturate coma in refractory ICP.

Focal Neurological Signs & NIHSS Elements

Key Focal Signs to Assess

Facial droop (upper vs lower motor neurone)
Arm drift (pronator drift test)
Grip strength asymmetry
Leg weakness — foot dorsiflexion
Aphasia / dysarthria
Hemineglect / inattention
Visual field defect (hemianopia)
Gaze deviation ("eyes look to lesion")

BIS Monitoring Basics

Bispectral Index (BIS): 0–100 scale of EEG-derived sedation depth
40–60: General anaesthesia / deep sedation target for barbiturate coma
60–80: Moderate sedation
80–100: Awake/light sedation
Used in refractory ICP with barbiturate coma: target BIS 40–55
EMG artefact common — check sensor placement

ICP Fundamentals

Normal ICP: <15 mmHg

Mild elevation: 15–20 mmHg

Moderate elevation: 20–30 mmHg

Severe elevation: >30 mmHg — urgent treatment

CPP = MAP − ICP
Target CPP: 60–70 mmHg
CPP <50 mmHg: critical cerebral ischaemia
CPP >70 mmHg: may worsen oedema

Tiered ICP Management

TIER 1 — First Line (All patients with raised ICP)

Head of bed 30° (neutral head position — avoid neck flexion/rotation)
Normocapnia: PaCO₂ 4.5–5.0 kPa (35–40 mmHg)
Normoglycaemia: glucose 6–10 mmol/L (avoid hypoglycaemia)
Normothermia: temp 36–37.5°C (treat fever aggressively)
CSF drainage via EVD (if in situ) — continuous or intermittent per protocol
Analgosedation: adequate analgesia before sedation (fentanyl + propofol/midazolam)
Avoid hypotension, hypoxia, and excessive stimulation

TIER 2 — Second Line (ICP unresponsive to Tier 1)

Osmotherapy: Mannitol 0.25–1 g/kg IV over 15–20 min (monitor serum osmolality <320 mOsm/kg) OR 3% hypertonic saline (bolus 150 mL or continuous infusion — target Na⁺ 145–155 mmol/L)
Short-term hyperventilation: PaCO₂ 4.0–4.5 kPa — use only as bridge (<30 min) due to rebound
Optimise sedation depth
Neuromuscular blockade if agitation causing ICP spikes

TIER 3 — Salvage Therapy (Refractory ICP)

Barbiturate coma: Thiopental or pentobarbital — target burst suppression on EEG; monitor BIS 40–55; requires vasopressor support
Decompressive craniectomy: Neurosurgical removal of skull flap to allow brain expansion; post-op nursing — craniectomy bone flap care
Therapeutic hypothermia (targeted temperature management 35–36°C)

EVD Nursing

Setup & Zeroing

Zero transducer at level of tragus of ear (external auditory meatus = foramen of Monro level)
Confirm zeroing at each position change and every shift
Drainage level set as prescribed (e.g. 10–15 cmH₂O above tragus)
Label all lines clearly — never flush an EVD

Ongoing Monitoring

Document CSF output hourly: volume, colour (clear/xanthochromic/bloody)
Normal CSF: clear, colourless; >30 mL/h may indicate CSF leak or over-drainage
Clamp EVD before repositioning patient — re-zero after
Record waveform morphology if continuous ICP monitoring active
Monitor ICP trend — document Lundberg A, B, C waves if present

Infection Prevention

Strict aseptic technique for all EVD interactions
Dressing change per local protocol (typically every 72h or if soiled)
CSF sampling: aseptic technique, physician order required
Monitor for: fever, neck stiffness, CSF turbidity — suspect ventriculitis
EVD-associated ventriculitis rate rises after day 5 — monitor WBC in CSF
Antibiotic-impregnated catheters reduce infection (rifampicin/clindamycin)

Complications & Troubleshooting

No drainage despite open system: check for kinks, obstruction, assess patient (herniation?)
Sudden loss of waveform: disconnection, obstruction, or transducer failure
Over-drainage: slit ventricle syndrome, subdural haematoma — reduce drainage height
Haemorrhage: report any sudden neurological deterioration immediately

Ischaemic Stroke — Thrombolysis (tPA/Alteplase)

Time is Brain: ~1.9 million neurones lost per minute without treatment. Door-to-needle target: <60 minutes.

Alteplase Protocol

Dose: 0.9 mg/kg (maximum 90 mg)
10% as IV bolus over 1 minute
Remaining 90% over 60 minutes by infusion
BP must be <185/110 mmHg before and during tPA
NIHSS must be documented before administration
Post-tPA: BP target <180/105 mmHg for 24 hours
No antiplatelets / anticoagulants for 24h post-tPA
No NG tube, arterial line (non-compressible sites) for 24h

tPA Contraindications

Symptom onset >4.5 hours (standard window)
Haemorrhagic stroke on CT
BP >185/110 mmHg uncontrolled
INR >1.7 or NOAC within 48 hours
Platelet count <100,000
Recent major surgery (<14 days)
History of intracranial haemorrhage

Large established infarct on CT (>1/3 MCA territory)

Mechanical Thrombectomy

Extended window: up to 24 hours from onset with penumbra imaging (DAWN/DEFUSE-3 criteria)
Requires large vessel occlusion (LVO): ICA, M1/M2 MCA, basilar artery
Performed in comprehensive stroke centres (CSC)
Can be combined with or used instead of tPA
Post-procedure nursing: groin puncture site monitoring, neurovascular obs, BP management

GCC Context: HMC (Qatar), KFSH (Saudi Arabia), and SKMC (Abu Dhabi) provide thrombectomy services. Telestroke networks expanding across GCC for remote triage.

Haemorrhagic Stroke

Blood Pressure Management

Target SBP <140 mmHg within 1 hour (ATACH-2 / INTERACT-2)
Avoid SBP <130 mmHg (may worsen perhaematoma ischaemia)
IV antihypertensives: labetalol, nicardipine, or urapidil
Monitor for haematoma expansion (early neurological deterioration)

Other Management

Reversal of anticoagulation: Vitamin K + PCC (4F-PCC) for warfarin; andexanet alfa for factor Xa inhibitors; idarucizumab for dabigatran
Neurosurgical referral: for cerebellar haemorrhage >3 cm or hydrocephalus
Repeat CT at 24h to assess expansion
DVT prophylaxis: IPC devices early; LMWH deferred 24–48h

Status Epilepticus — Time-Sensitive Treatment

Definition: Seizure lasting >5 minutes OR 2 seizures without recovery of consciousness between them. Every minute of untreated SE causes neuronal injury.

Phase 1 — 0–5 minutes: Stabilisation

Position patient laterally (recovery position) — airway protection
Apply supplemental oxygen (high-flow mask)
Check blood glucose — treat hypoglycaemia (glucose 50 mL of 50% dextrose IV)
Secure IV/IO access
Monitor SpO₂, ECG, BP
Draw blood: FBC, U&E, glucose, Mg, Ca, AED levels, toxicology

Phase 2 — 5–30 minutes: First-Line Benzodiazepines

IV available: Lorazepam 0.1 mg/kg IV (max 4 mg/dose, may repeat once)
No IV access: Midazolam 10 mg IM (adult) — buccal or intranasal midazolam alternatives
Diazepam 0.15 mg/kg IV alternative (rectal route available)
Repeat benzodiazepine once after 5 min if no response

Phase 3 — 30–60 minutes: Second-Line AEDs

Levetiracetam: 60 mg/kg IV (max 4500 mg) over 10 min — preferred (fewer interactions)
Valproate: 40 mg/kg IV (max 3000 mg) over 10 min — avoid in pregnancy/liver disease
Lacosamide: 200–400 mg IV over 15 min — option for focal SE
Phenytoin 20 mg/kg IV (15 min) — older option, significant cardiac monitoring required

Phase 4 — >60 minutes: Refractory Status Epilepticus

Intubation and mechanical ventilation
Anaesthetic agents (titrate to burst suppression on EEG):
Propofol infusion: 1–2 mg/kg bolus, then 2–10 mg/kg/h (monitor for PRIS with prolonged use)
Midazolam infusion: 0.2 mg/kg bolus, then 0.05–2 mg/kg/h
Thiopental: 100–250 mg bolus, 3–5 mg/kg/h — ICU/anaesthetic setting only
Continuous EEG monitoring — target burst suppression
Transfer to NICU

EEG Monitoring & Non-Convulsive SE

Non-Convulsive SE (NCSE) Recognition

NCSE is frequently missed — suspect in any patient with unexplained altered consciousness after seizure activity or in ICU patients.

Subtle eye deviation (nystagmus-like or persistent gaze preference)
Subtle facial or limb twitching
Impaired consciousness without obvious motor signs
Post-ictal confusion persisting >30 minutes
Cyclic fluctuations in consciousness level
Diagnosis requires: continuous EEG (cEEG) monitoring

EEG Monitoring — Nursing Role

Electrode application: correct placement, conductive gel, secure leads
Document patient activities (stimulation, procedures, medication) on EEG record
Maintain electrode impedance <5 kΩ
Report to physician: electrographic seizures, periodic discharges, status patterns
Prolonged EEG (24–72h) recommended for suspected NCSE in NICU

Subarachnoid Haemorrhage — Grading

Hunt & Hess Grade (Clinical)

Grade	Clinical Features	Prognosis
I	Asymptomatic or mild headache	Good
II	Severe headache, nuchal rigidity, no deficit	Good
III	Drowsy, mild deficit	Moderate
IV	Stupor, hemiparesis	Poor
V	Coma, decerebrate posturing	Very Poor

Modified Fisher Grade (CT Haemorrhage)

Grade	CT Findings	Vasospasm Risk
1	Thin SAH, no IVH	Low
2	Thin SAH + IVH	Moderate
3	Thick SAH, no IVH	High
4	Thick SAH + IVH	Highest

Aneurysm Securing

Endovascular Coiling

Platinum coils deployed via catheter into aneurysm sac
Preferred for most posterior circulation and elderly patients
Post-procedure: groin site monitoring, neuro obs, antiplatelet therapy
Lower risk of cerebral vasospasm post-procedure

Surgical Clipping

Metal clip applied to aneurysm neck via craniotomy
Preferred for large/complex aneurysms, young patients, MCA aneurysms
Post-operative neurosurgical nursing: ICP monitoring, wound care
Direct aneurysm exclusion — definitive

Rebleeding Prevention: SBP target <160 mmHg before aneurysm secured. Rebleeding carries 80% mortality. Secure aneurysm within 24–72h of presentation.

Vasospasm Monitoring

Vasospasm peak: days 4–14 post-SAH. Most dangerous complication causing delayed cerebral ischaemia (DCI). Nimodipine 60 mg q4h for 21 days for ALL SAH patients — reduces DCI outcomes.

Transcranial Doppler (TCD) Monitoring

Daily TCD from day 2–14 post-SAH
MCA mean velocity >120 cm/s = vasospasm; >200 cm/s = severe
Lindegaard ratio (MCA/ICA) >3 = vasospasm (differentiates from hyperaemia)
TCD must be combined with clinical neurological assessment

Clinical Monitoring

Hourly neurological assessment (GCS, focal signs) during vasospasm window
New onset confusion, focal deficit, or GCS drop = suspect vasospasm
CT perfusion or CTA to confirm delayed cerebral ischaemia
Maintain euvolaemia (avoid hypovolaemia) — Triple-H therapy largely superseded

Nimodipine Protocol

Nimodipine 60 mg every 4 hours orally for 21 days — ALL SAH patients
Oral/NG route preferred — do not give IV nimodipine via central line (error risk)
Monitor BP: nimodipine can cause hypotension — may need dose reduction to 30 mg q2h
Do NOT confuse nimodipine (SAH) with nifedipine (hypertension)

Endovascular Rescue for Vasospasm

Intra-arterial nimodipine / verapamil infusion
Balloon angioplasty for proximal vessel vasospasm
Requires angiography suite — liaise with interventional neuroradiology team

SAH Complications

Hydrocephalus

Occurs in ~20% of SAH — acute or delayed
Acute: blood blocks CSF reabsorption at arachnoid granulations
Treatment: EVD placement — drain to ICP target
Delayed (weeks–months): communicating hydrocephalus — may require VP shunt

Hyponatraemia in SAH

Critical Distinction: Cerebral Salt Wasting (CSW) vs SIADH — treatment is opposite!

	CSW	SIADH
Volume status	Hypovolaemic	Euvolaemic
Urine Na⁺	High	High
Treatment	Fluid + Na⁺ replacement	Fluid restriction

CSW is more common in SAH. Fluid restriction in CSW causes cerebral ischaemia — avoid unless SIADH confirmed.

Neurocritical Care in the GCC

Major Centres with Dedicated NICUs

KFSH (King Faisal Specialist Hospital), Riyadh & Jeddah — Neuroscience Institute, dedicated NICU
HMC (Hamad Medical Corporation), Doha — Neurocritical care programme, comprehensive stroke centre
SKMC (Sheikh Khalifa Medical City), Abu Dhabi — Integrated neurosciences, NICU
NMC / Cleveland Clinic Abu Dhabi — Neurological Institute
KIMS / Kuwait — Neurosurgical ICU

Road Traffic Accidents — TBI in GCC

GCC countries have among the highest road traffic fatality rates globally. RTA-related TBI is a leading cause of NICU admissions across the region.

Saudi Arabia: ~17 deaths per 100,000 population (WHO data)
Young male demographic predominates (labour workforce, driving culture)
High-velocity trauma — diffuse axonal injury, polytrauma
Implications: high NICU capacity demand, family communication in multiple languages

Regulatory Competency Frameworks

DHA (Dubai)

DHA Licensure Exam: critical care neuro section
DOH (Abu Dhabi) scope of practice: neurocritical nursing competencies
Emirates Nursing Council standards

SCFHS (Saudi Arabia)

Saudi Commission for Health Specialties critical care content
Neurocritical nursing: ICP, stroke, SE, SAH
Saudi Nursing Council competency framework

QCHP (Qatar)

Qatar Council for Healthcare Practitioners registration
HMC competency-based critical care nursing framework
Arabic language requirements for patient communication

Arabic GCS & Cultural Communication

Arabic Glasgow Coma Scale

Validated Arabic version of GCS available for clinical use in Arabic-speaking patients
Important for accurate verbal response assessment (V component)
Confusion vs oriented responses require language-matched assessment
Documentation in patient language of choice per local policy
Interpreter services essential when direct Arabic assessment not possible

Family Communication in Arabic

Family-centred communication is culturally paramount in GCC
Senior male family member often designated primary contact (respect this while ensuring patient rights)
Use certified medical interpreters — not family members for clinical decisions
Explain prognosis with sensitivity and cultural humility
Regular family meetings — structured communication reduces anxiety

Islamic End-of-Life & Brain Death — GCC Legal Frameworks

Brain Death Determination: Legal and religious frameworks differ across GCC nations. Nurses must be familiar with local institutional policy and country-specific law.

Saudi Arabia

Brain death legally accepted per Saudi Health Council regulations
Islamic Fiqh Academy (OIC) recognises brainstem death as death
Organ donation permitted with family consent
SCOT (Saudi Center for Organ Transplantation) oversees donation

UAE

Federal Law No. 5 (1995) addresses brain death and organ donation
Brain death criteria require two senior physicians confirmation
Family must be informed and consent obtained
End-of-life care: respect for Islamic burial rites and family presence

Qatar

Qatar Law No. 15 (2015): organ donation and transplantation law
Brain death determination: clinical criteria + confirmatory tests
HMC guidelines: family discussion before withdrawal of life-sustaining treatment
All end-of-life decisions: senior physician + ethics committee involvement

Nursing Role: Support family with compassion during brain death discussions. Document all communications. Ensure patient dignity and Islamic post-mortem care is facilitated promptly after death declaration.

GCC Neurocritical Care — Exam MCQs

Q1. A 45-year-old patient post-TBI has ICP 24 mmHg and MAP 84 mmHg. What is the CPP, and what is the most appropriate first-line intervention?

A) CPP 60 mmHg — administer mannitol 1 g/kg immediately B) CPP 60 mmHg — ensure head 30°, normocapnia, normothermia, adequate sedation (Tier 1) C) CPP 108 mmHg — no intervention needed D) CPP 60 mmHg — proceed immediately to decompressive craniectomy

CPP = MAP − ICP = 84 − 24 = 60 mmHg (at lower limit of target 60–70 mmHg). ICP 24 mmHg = moderate elevation. Tier 1 measures (positioning, normocapnia, normothermia, analgosedation) should be optimised first before escalating to osmotherapy (Tier 2) or craniectomy (Tier 3).

Q2. A patient with aneurysmal SAH (day 7) develops new left hemiparesis and confusion. What is the most likely diagnosis and immediate nursing priority?

A) Rebleeding — prepare for emergency return to theatre B) Cerebral vasospasm — notify physician urgently, ensure nimodipine is prescribed, prepare for TCD/CT perfusion C) Hyponatraemia — restrict fluids immediately D) Hydrocephalus — open EVD to maximum drainage

Vasospasm peaks days 4–14 post-SAH. New neurological deficit at day 7 is vasospasm until proven otherwise. Nimodipine 60 mg q4h for 21 days is standard of care. Fluid restriction for suspected hyponatraemia is dangerous if cerebral salt wasting (most common in SAH) — differentiate CSW from SIADH before treating.

Q3. A patient presents with tonic-clonic seizure lasting 8 minutes in the ED. No IV access is available. Which is the most appropriate immediate treatment?

A) Wait for IV access before giving any medication B) Levetiracetam 60 mg/kg IV as soon as access is obtained C) Midazolam 10 mg IM immediately while IV access is being established D) Phenytoin 20 mg/kg IV bolus as fast as possible

Phase 2 (5–30 min): benzodiazepines are first line. Without IV access, IM midazolam 10 mg is the preferred alternative (RAMPART trial showed non-inferior to IV lorazepam). Buccal or intranasal midazolam are alternatives. Levetiracetam is Phase 3 (30–60 min) second-line agent. Phenytoin requires cardiac monitoring and slow infusion rate.

Q4. When zeroing an EVD, the nurse should level the transducer at which anatomical landmark?

A) The mastoid process B) The tragus of the ear (external auditory meatus) C) The top of the patient's head D) The mid-axillary line

The tragus of the ear is the surface landmark corresponding to the foramen of Monro (interventricular foramen), which is the standard zero reference for ICP and EVD pressure monitoring. The mid-axillary line is used for arterial and CVP transducers (right atrium level).

Q5. A patient with ischaemic stroke is eligible for tPA. Their current BP is 190/115 mmHg. What is the appropriate action before administering alteplase?

A) Administer tPA immediately — BP is not a contraindication B) Withhold tPA permanently — BP >185/110 is an absolute contraindication C) Treat BP to <185/110 mmHg with IV antihypertensives, then administer tPA if target is achieved D) Administer tPA and start antihypertensives simultaneously

BP >185/110 mmHg is a contraindication to tPA. However, this is a manageable contraindication — BP should be treated with IV agents (labetalol, nicardipine) to achieve <185/110 mmHg before tPA administration. If BP cannot be controlled to this target, tPA should be withheld. Post-tPA target is <180/105 mmHg for 24 hours.
