Baclofen overdose can also mimic brain death, Another caveat pertains to the trauma patient ocular movements may be impaired if a blowout fracture has trapped the extraocular muscles, patients that chronically wear contact lenses may have diminished corneal reflexes, loss of the corneal reflex is usually a late sign in coma, traditional method is to stroke the cornea with cotton wool, corneal stimulation can also be performed by dropping a few drops of sterile saline onto the cornea from a height of 10 cm (less traumatic), reflex is present and intact if the patient blinks and eyes roll upwards, efferent: CN7 (blink) and CN3 (eye movement), indicates that the ponsandmidbrainare intact (the reflex pathway involves the trigeminal nerve, the spinal CN5 nucleus, the lateral brainstem tegmentum, and the CN3 and CN7 nuclei), If the eye turns upwards but the eyelid does not close there is a CN7 lesion (Bells phenomenon), If the eye does not turn upwards and the eyelid does not close there is a CN5 lesion, may be absent in normal people and those accustomed to an endotracheal tube, best assessed using a laryngoscope and a tongue depressor in intubated patients, look for bilateral palatal elevation, can be stimulated by a suction catheter down and endotracheal tube, Abnormal flexion is decorticate posturing adduction of arm, internal rotation of shoulder, pronation of forearm, flexion of wrist (lower limbs are extended); indicatesa lesion above the brainstem, Extension is decerebrate posturing abduction of arm, external rotation of shoulder, supination of forearm, extension of wrist (lower limbs are extended); indicates alesion extending to the midbrain or below, involuntary movements (such as subtle signs of seizures and myoclonus), consider the neurological findings in light of the vital signs, evidence of trauma or shock, acute or chronic illness, and/or drug ingestion, track marks, drug paraphernalia and toxidromes, Look in the fundi for papilloedema, diabetic or hypertensive retinopathy, or subhyaloid haemorrhage. If you have a problem with the muscles, the eyes don't work properly. Predictive modelling concluded that a combination of education and responsiveness monitoring would result in a 1011% improvement in proportion of shifts with optimal sedation without an increase in sedation-related adverse events.

Your article on prognostication in cardiac arrest was very helpful. introduce iced water into the external ear canal through a small catheter until one of the following occurs: allow 5 minutes between testing ears to allow re-equilibration of the oculovestibular system, as consciousness is lost, the fast component (towards the non-irrigated ear) is lost and the slow component tonically deviates the eye in the direction of the irrigated ear, If the brainstem is intact, cold water causes the eyes to deviate downwards and warm water causes the eyes to deviate upwards, Brainstem encephalitis, deep metabolic coma and certain drugs may mimic brainstem death, Drugs include recently administered anticonvulsants such as phenytoin and barbiturates. Thanks for all the helpful information. They assessed that overall risk of bias as high or unclear particularly with relation to blinded outcome assessors.

In the sedation group, the mean RASS score was 2.3 on day 1 increasing to 1.8 by day 7, and in the non-sedation group the mean RASS score was 1.3 on day 1 and 0.8 on day 7. These guidelines included 37 actionable recommendations and 2 best practice statements. The final analysis included 3904 patients and rates of death were similar in both groups at 90 days.

Inhalational volatile-based sedation for COVID-19 pneumonia and ARDS. Lateral gaze deviation from a pontine lesion, Vertical separation of the ocular axes is calledskew deviation, This is suggestive of a pontineorvestibulocerebellarlesion on the side of the inferior eye, or amedial longitudinal fasciculuslesion on the side of the superior eye, the head is briskly turned from side to side with the head held briefly at the end of each turn, a positive response occurs when the eyes rotate to the opposite side to the direction of head rotation, thus indicating that the brainstem (CN3,6,8) is intact, a similar result is seen when the head is flexed and extended a positive result is downward deviation of the eyes during extension, and upward deviation during flexion (the eyelids, if closed, may also open as part of the dolls head phenomenon). For true changes in pupillary response, expect the physician to order further diagnostic tests, such as a CT scan. Neurologic features in severe SARS-CoV-2 infection.
