It is a common misconception that people in comas do not require any maintenance or care. In reality, a person in a coma still requires a great deal of care and attention, including regular hygiene functions such as bathing, teeth brushing, and nail trimming. In fact, a person's hair and nails continue to grow while they are in a coma and must be maintained by nurses or aides. Additionally, the heart is still beating, and the patient's overall health can impact the rate of nail growth. Furthermore, the Glasgow Coma Scale, a universally used test for consciousness, has been found to have unintended side effects, including discoloured fingernails due to repeated prods and pokes to assess consciousness.

What You'll Learn
Nails continue to grow while in a coma
Fingernails and toenails continue to grow while a person is in a coma. The average rate of growth for fingernails is about a tenth of a millimeter per day or 3.47 millimeters per month. Toenails, on the other hand, grow at a slower rate of about 1.62 millimeters per month.
Several factors can influence the rate of nail growth. One factor is hand dominance, with nails on the dominant hand growing faster due to increased use and risk of trauma. Additionally, the specific finger also affects growth rate, with the little finger's nail growing slower than the others. Age is another factor, as nail growth tends to slow down as we get older due to a decrease in blood circulation. Hormone levels can also play a role, with pregnancy and puberty being associated with rapid nail growth.
While in a coma, the patient's nails will be trimmed regularly by nurses and nurse aides as part of their personal care routine. This routine also includes maintaining the patient's hygiene, such as bathing, brushing teeth, and shaving or trimming facial hair. The nurses also clean and check the sites where any tubes are inserted for signs of infection.
In some cases, patients in a coma may experience coma nails, a phenomenon where their fingernails become discolored. This was reported in a 1997 article from the Journal of Neurology, Neurosurgery, and Psychiatry, which linked it to the repeated use of the Glasgow Coma Scale assessment, where a patient's fingers are prodded to test for reactions to pain.

Nurses maintain hygiene, including trimming nails
Maintaining nail hygiene is an essential aspect of nursing, as it directly impacts both personal and patient health. Nails can be a breeding ground for bacteria and pathogens, and improper nail care can increase the risk of spreading infections. Therefore, nurses are instructed to keep their nails short and clean, minimizing the chances of contamination and adhering to healthcare standards.
Nurses play a crucial role in supporting patients' hygiene needs, and this includes nail care. They establish a structured approach to assist clients in maintaining optimal nail hygiene. This involves creating a schedule that considers the patient's preferences and specific needs, such as a diabetic foot care regimen. Nurses also set clear and achievable goals, which may include regular trimming, moisturizing cuticles, and inspecting nails for any signs of infection or injury. Educating patients on the importance of nail hygiene empowers them to take care of their nails and prevents complications like fungal infections.
In addition to patient care, nurses must also maintain their own nail hygiene to ensure safe and efficient nursing practices. Short nails facilitate thorough handwashing, which is critical for preventing the spread of infections between patients. Long or poorly maintained nails can hinder a nurse's ability to perform tasks requiring dexterity and precision, such as inserting IV lines. Therefore, nurses are advised to trim their nails regularly, keeping them no longer than 1/4 inch beyond the fingertip.
Furthermore, nurses should avoid artificial nails, including acrylics, gels, and dip powder manicures. These have been discouraged in the healthcare profession due to their potential to harbor bacteria and impede proper hand hygiene. The World Health Organization (WHO) Guidelines on Hand Hygiene in Health Care (2009) specifically identify artificial fingernails as a risk factor for changes in normal flora and ineffective hand hygiene.
Overall, nail care is a vital component of nursing hygiene practices. By maintaining short, clean nails and educating patients about nail hygiene, nurses can prevent infections, ensure patient safety, and enhance the quality of care they provide.

Fingernails grow faster than toenails
There are several theories as to why fingernails grow faster than toenails. One theory, called the "terminal trauma" theory, suggests that the more you use a digit, the quicker the nail grows. This is because the body assumes that fingernails are being worn down by constant use and therefore increases the growth rate to compensate. Toenails, on the other hand, are generally protected by shoes and are subject to less trauma, resulting in slower growth.
Another theory suggests that the rate of nail growth is directly related to the amount of blood flowing through the digit. Since the hands are closer to the heart than the feet, more blood flows through the fingers, resulting in faster nail growth. This theory also explains why nails grow slower in cold weather when blood flow is restricted.
Other factors that can affect nail growth rate include age, gender, nutrition, season, and individual factors such as handedness and illness. Nails tend to grow faster on the dominant hand, during the summer, and in men and pregnant women. Overall, while the exact mechanisms controlling nail growth are not fully understood, it is clear that fingernails consistently grow faster than toenails.

Factors affecting nail growth rate
Fingernails grow at a standard rate of between 0.5 and 1.2 mm per week, or about 0.1 mm per day. Toenails grow at a slower rate of about 1.62 mm per month. However, several factors can influence the rate of nail growth.
One factor is the finger on which the nail grows. Typically, the nails on the dominant hand and the longer fingers grow faster. For example, the little finger nail grows slower than other fingernails. The rate of growth can also vary by up to 0.1 mm between nails on the same hand.
Age is another factor that affects nail growth. As people age, their blood circulation slows down, leading to a decrease in nail growth. For example, a study by Dr. William Bean found that his left thumbnail growth rate decreased from 0.123 mm per day at age 23 to 0.095 mm per day at age 67.
Hormone levels also play a role in nail growth rates. For instance, pregnancy can cause rapid nail growth, while lactation may decrease nail growth. Puberty is another period of fluctuating hormone levels, with nail growth peaking during this time and then declining as hormone levels stabilize.
The time of year can also impact nail growth, with nails growing faster during the summer months. Additionally, maintaining good nail hygiene practices, such as regular trimming and moisturizing, can promote healthy nail growth.

Nails may be discoloured post-coma
A person emerging from a coma may find that their nails are discoloured. This is due to the side effects of a common medical assessment for consciousness, known as the Glasgow Coma Scale. This test is used to determine a patient's level of consciousness and alertness and involves applying noxious pain stimuli to the patient's finger to observe any reaction. Repeated prods and pokes can result in the patient's fingernails turning black and blue, a phenomenon sometimes referred to as "Coma Nails".
The discolouration is caused by bilateral subungual haematomas, or lesions, formed by frequent nail bed compression with a pencil during the Glasgow Coma Scale evaluations. These evaluations are routinely performed on comatose patients in neurological intensive care units to monitor their motor response.
While this procedure is essential for assessing a patient's level of consciousness, it can result in unintended cosmetic side effects, such as nail discolouration. This can be distressing for individuals who value their nail appearance and may require additional nail care post-coma.
It is important to note that not all comatose patients will experience nail discolouration. The occurrence of "Coma Nails" depends on the frequency and force of the pencil prods during the Glasgow Coma Scale assessments. Additionally, for individuals who typically paint their nails or are accustomed to wearing artificial nails, the discolouration may go unnoticed until the nail cosmetics are removed.
