What are the brain stem reflexes?
Reflexes of the brain stem are involuntary reactions to stimuli mediated brain, an important part of the anatomy of the brain responsible for a number of different functions. If these reflexes are depressed or absent, this is evidence of the brain stem damage. In the clinical instructions used to determine the death of the brain, the providers of the care are checked by several reflexes of the brain stem to determine whether the brain strain is still functional. If this is not the case, the patient is unable to survive separately and can be considered clinically dead.
Brainst contains a number of sensory connections. He is responsible for the innervate face and nerves that process the sensory entry from the rest of the body, pass through this structure on the way to Misha. If there is a problem with the brain, such as swelling, cell death or injury pressure, the patient's brain stem may be missing. Some medicines can potentially create the appearance of absent reflexes, and this is to be considered when evaluating the patient on signs of brain damage.
Many reflexes mOzka concentrates around the eye. When the care provider places the object near or in the eye, the patient should involuntarily flash, reflective reactions to the protection of the eye from damage. Exposure to bright light should cause pupils to download and leave less light into the eye.
If the patient's head is turned to test the eye reflex, the eyes follow the opposite direction. In the event of the death of the brain, the eyes remain repaired again. Another reflex, an ocular -stibular reflex, includes irrigation of the ear with cold water to see if the eyes are moving in the opposite direction.
other reflexes of the brain stem include cough and gag when the neck is irritated, as when a nurse moves the endotracheal tube. In the inhibitory reflex of the master, clicking on the jaw, while the mouth is opening slightly up. These reflexes help the body avoid injuries and help with functions such as eating, balance and see clearly. IfIt means that the brain stem is no longer able to send or receive the necessary signals.
drugs can suppress brain reflexes. For example, many drugs cause pupils to dilate. In these patients, bright light does not cause the expected contraction of pupils. Care providers carefully check the patient's chart to determine the nature of the injury and all the drugs that are used before moving forward with a number of tests to assess reflexes of the brain stem. These tests are also repeated and verified by means other than the patient's dead brain.
