Archived from the original on 6 March A deeper coma alone does not necessarily mean a slimmer chance of recovery, because some people in deep coma recover well while others in a so-called milder coma sometimes fail to improve.
If management of unconscious patient pdf download patient’s eyes move in a direction opposite to the direction of the rotation of the head, then the patient is said to have an intact brainstem.
Certain stereotypical patterns of breathing have been identified including Cheyne—Stokesa form of breathing in which the patient’s breathing pattern is described as alternating episodes of hyperventilation and apnea. It may also be deliberately induced by pharmaceutical agents during major neurosurgeryto preserve higher brain functions following brain management of unconscious patient pdf downloador to save the patient from extreme pain during healing of injuries or diseases.

Cortex is responsible for a rapid nystagmus away from this deviated position and is often seen in patients who are conscious or merely lethargic. In the initial assessment of coma, it is common to gauge the level of consciousness by spontaneously exhibited actions, response to vocal stimuli “Can you hear me? More elaborate scales, such as the Glasgow Coma Scalequantify an individual’s reactions such as eye opening, movement and verbal response on a scale; Glasgow Coma Scale GCS is an indication of the extent of brain injury varying from 3 indicating severe brain injury and death to a maximum management of unconscious patient pdf download 15 indicating mild or no brain injury.

In the first level, the brain responsiveness lessens, normal reflexes are lost, the patient no longer responds to pain and cannot hear.
Image of the man still unresponsive to stimuli. Caloric reflex test also evaluates both cortical and brainstem function; cold water is injected into one ear and the patient is observed for eye movement; if the patient’s eyes slowly deviate toward the ear where the water was injected, then the brainstem is intact, however failure to deviate toward the injected ear indicates damage of the brainstem on that side.
