Coma is a state of prolonged unconsciousness that can be caused by a variety of problems — traumatic head injury, stroke, brain tumor, drug or alcohol intoxication, or even an underlying illness, such as diabetes or an infection. The longer the coma, the larger and more diffuse the area of damage, the older the person, the less are the chances of reversal of the coma and recovery of function. Coma Recovery Scale-Revised (CRS-R) scores improved with increased VNS intensity, from 5 at baseline to 10 at 1.00-1.25 mA, which the investigators claimed indicated a … A fully conscious patient has a Glasgow Coma Score of 15. A coma is defined as a ‘profound state of unconsciousness’ wherein a person is unable to be wakened. Coma is a state of unarousable unresponsiveness characterized by the deficiency of the arousal systems (clinically assessed as the absence of stimulation-induced eye opening after having ruled out bilateral ptosis) and thus also by absence of awareness. In a coma, a patient is alive and there is some brain activity. In addition, elec-SLEEP VS COMA Coma is a medical emergency. A coma is a deep state of eyes-closed unconsciousness where a person is not able to respond to people or the environment around them. Propofol/Diprivan and/or Midazolam/Versed) and opioids(=strong killers I.e. Since a PVS is a late stage outcome of causes of irreversible coma, or the end stages of a dementia, the outlook for recovery is always poor for a person in this state. Assessment of coma. Coma is an acute, life threatening situation. A patient who awakens from a coma may also develop a so-called locked-in syndrome, being completely conscious but paralyzed and unable to communicate, except through eye blinks. A person who is comatose will have no response to stimuli- other than (possibly) painful stimuli. An induced coma is a medically induced coma where critically ill Patients are put asleep by powerful sedatives(I.e. Someone in a coma is described as being ‘comatose’. opening their eyes or moving when touched). Another way to think of it is in terms of sedation. The comatose patient lacks the sleep–wake cycles that can be observed in the VS. Depending on the severity of the injury, recovery time varies and comas can be … They will not respond to pain, light, sound or other stimulation, and they will not have the usual ‘sleep-wake cycles’. Swift action is needed to preserve life and brain function. A person who is semi-comatose may be somewhat responsive to physical or verbal stimuli (i.e. Coma. There are many different conditions that can result in coma. Think of the Glascow coma scale. The goal of a neurological examination in a comatose patient is to determine if the coma is induced by a structural lesion or from a metabolic derangement, or possibly from both. Fentanyl, Morphine, Remifentanyl) in order to be able to tolerate mechanical ventilation and a … comatose patients will never open the eyes, not even when intense or noxious stimuli are applied. Patients evolving from a coma to a vegetative state may, in turn, be com-pared to sleepwalkers – only showing reflex or automatic behavior, but not command following (Laureys, 2005). The Rancho Level of Cognitive Functioning Scale (LCFS) is a scale used to assess cognitive functioning in people with brain injury.
