How should I manage a patient who remains unresponsive for one hour, only moans, has reactive pupils and upward eye rolling?

Immediate Management of Unresponsive Patient with Moaning, Reactive Pupils, and Eye Rolling

This patient requires urgent systematic evaluation to exclude life-threatening causes, with immediate focus on ruling out confounders (sedation, metabolic derangements), assessing brainstem function through structured neuro-ophthalmic examination, and determining if this represents evolving brain injury requiring emergent intervention.

Initial Critical Actions

1. Rule Out Reversible Confounders First

Before attributing unresponsiveness to structural brain injury, you must systematically exclude 1:

• Residual sedation/medications: If any sedatives were given, wait at least 5 elimination half-lives (minimum 24 hours for propofol, longer for other agents). Consider flumazenil for benzodiazepines if suspected, but use cautiously as it may precipitate seizures
• Metabolic derangements: Check glucose, sodium, calcium, liver/kidney function, ammonia, thyroid function
• Severe hypotension: Ensure adequate cerebral perfusion pressure
• Hypothermia: Core temperature must be normal
• Sepsis: Check for systemic infection

2. Structured Neuro-Ophthalmic Assessment

The "unrolling of eyes" you describe requires precise characterization 2:

Determine the pattern of abnormal eye movements:

• Spontaneous roving eye movements (ping-pong gaze): Suggests bilateral cerebral hemisphere dysfunction but relatively intact brainstem
• Ocular bobbing (fast downward, slow upward): Strongly suggests structural pontine lesion, especially if reflexive eye movements are absent
• Upward deviation: May indicate thalamic or midbrain dysfunction
• Disconjugate deviation: Consider cranial nerve palsies or decompensated strabismus

Test reflexive eye movements to assess brainstem integrity 2, 3:

• Oculocephalic reflex (doll's eyes): Turn head horizontally - eyes should move opposite direction and hold position. If eyes drift back to midline rapidly (time constant <1.5 seconds), this indicates severe brainstem/cerebellar dysfunction 3
• Corneal reflex: Must be tested bilaterally - absence bilaterally at ≥72 hours predicts poor outcome 1

3. Pupillary Examination - Critical Prognostic Indicator

You report reactive pupils, which is actually a favorable sign 1, 4:

• Use quantitative pupillometry if available rather than subjective assessment - it's more sensitive and reduces false-positive predictions of poor outcome 1, 4
• Neurological Pupil Index <1.6 suggests brain herniation syndrome (91% specificity) 4
• Bilaterally absent pupillary AND corneal reflexes at ≥72 hours is one of the strongest predictors of poor outcome when combined with other signs 1
• Decreased brainstem blood flow causes pupillary abnormalities more often than mechanical compression 5

Glasgow Coma Scale Assessment

Document motor response precisely 1:

• Moaning alone = GCS Motor score <6 (not obeying commands)
• If motor response is ≤3 (abnormal flexion or worse) at ≥72 hours with confounders excluded, this triggers formal prognostication algorithm

Diagnostic Workload

Immediate imaging:

• Brain CT/MRI: Look for diffuse anoxic injury, herniation, structural lesions, pontine pathology

Neurophysiologic testing (if post-cardiac arrest or suspected anoxic injury) 1:

• Somatosensory evoked potentials (SSEPs): Bilaterally absent N20 wave at ≥24 hours is highly specific for poor outcome. Use neuromuscular blockade during testing to reduce artifacts
• EEG: Assess for status myoclonus (continuous generalized myoclonus ≥30 minutes), highly malignant patterns, or seizure activity
• Serum NSE: If >60 µg/L at 48-72 hours, adds to poor outcome prediction

Prognostic Framework (If ≥72 Hours Post-Insult)

Poor outcome is very likely when ≥2 of the following are present 1:

1. No pupillary AND corneal reflexes at ≥72 hours
2. Bilaterally absent N20 SSEP wave at ≥24 hours
3. Highly malignant EEG at >24 hours
4. NSE >60 µg/L at 48/72 hours
5. Status myoclonus ≤72 hours
6. Diffuse extensive anoxic injury on brain CT/MRI

This multimodal approach has 0% false-positive rate compared to 7% with older stepwise strategies 1.

Critical Pitfalls to Avoid

• Do not prognosticate before 72 hours unless confounders are definitively excluded
• Do not rely on pupillary exam alone - requires correlation with other brainstem reflexes and imaging
• Reactive pupils do NOT rule out severe brain injury - they must be interpreted in context of overall examination 1, 4
• Abnormal eye movements require precise characterization - "eye rolling" is too vague; determine if spontaneous vs. reflexive, conjugate vs. disconjugate, pattern and timing 2
