Coma scale score of 5 or 6?


Hello, Doctor.
I would like to ask about my mother, who suffered a ruptured intracranial aneurysm on March 7.
The doctors mentioned that there is significant hypoxia in the left hemisphere of her brain.
Currently, she has a nasogastric tube and a tracheostomy in place.
After the surgery, her Glasgow Coma Scale score has consistently been between 5 and 6.
While in the hospital, she showed some resistance when her limbs were stimulated, but now, nearly a month later, she remains in a comatose state.
I would like to know what the prognosis is for patients like my mother— is there a possibility that she may regain consciousness? Additionally, she has been transferred to a care facility, but her body temperature has been consistently between 37.5 and 38 degrees Celsius.
We can only use ice packs to help lower her temperature.
Could you please advise on the impact of elevated body temperature on her condition, and whether it would be better to use medication to reduce her fever or continue using ice packs to cool her down?

A coma scale score of 5-6 indicates that awakening is quite difficult.
Alternating between an ice pack and medication can be used to reduce fever.

Understanding coma levels and recovery potential after a brain aneurysm rupture is a complex and nuanced topic. Your mother's situation, with a Glasgow Coma Scale (GCS) score consistently between 5 and 6, indicates a severe level of impairment. The GCS is a scale used to assess a patient's level of consciousness, with scores ranging from 3 (deep coma) to 15 (fully awake). A score of 5 or 6 suggests that your mother is in a state of profound coma, which can complicate recovery.

In general, the prognosis for recovery from a coma can vary significantly based on several factors, including the duration of the coma, the underlying cause, and the extent of brain injury. In cases of brain aneurysm rupture, factors such as the location of the aneurysm, the amount of bleeding, and the time taken to receive medical intervention can all influence outcomes. While some patients may regain consciousness after a prolonged period, others may remain in a persistent vegetative state or suffer from severe cognitive and physical impairments.

Regarding your mother's potential for recovery, it is difficult to provide a definitive answer without comprehensive neurological assessments and imaging studies. However, it is important to remain hopeful, as there are documented cases where individuals with low GCS scores have eventually regained consciousness, albeit the timeline can be unpredictable. Continuous stimulation and rehabilitation efforts, even in a comatose state, can sometimes facilitate recovery.

As for the elevated body temperature (37.5 to 38 degrees Celsius), this can be concerning, especially in a patient with a severe brain injury. Elevated body temperature can exacerbate brain injury and may indicate an underlying infection or other complications. It is crucial to monitor her temperature closely, as fever can lead to increased metabolic demands on the brain, which may hinder recovery.

In terms of managing her fever, both pharmacological and non-pharmacological methods can be effective. Antipyretic medications, such as acetaminophen or ibuprofen, can help reduce fever and are often used in clinical settings. However, physical methods, such as using ice packs or cooling blankets, can also be beneficial. The choice between medication and physical cooling methods may depend on her overall clinical status and any contraindications to medication use. In many cases, a combination of both approaches is utilized to effectively manage fever.

In summary, while your mother's prognosis remains uncertain, it is essential to maintain open communication with her medical team regarding her condition and treatment options. Regular assessments and adjustments to her care plan can help optimize her recovery potential. Additionally, addressing her elevated body temperature promptly is crucial to prevent further complications. Your involvement and advocacy for her care are vital during this challenging time.
