Introduction
Comatose patients are generally unable to undergo muscle strength assessment because they cannot cooperate with the doctor to perform various movements. Muscle strength evaluation must be conducted when the patient is conscious, based on muscle contraction and joint movement. Nursing care for comatose patients is essential, including monitoring urine output, urination patterns, and changes in urine color; any abnormalities should be promptly reported to the physician.
Comatose patients generally cannot undergo muscle strength assessment, which primarily requires the patient to be conscious. Muscle strength is evaluated based on muscle contraction and joint movement.
After observing muscle contraction and joint activity, if there is no complete muscle contraction and no joint movement, muscle strength is typically classified as grade 0. If only muscle contraction occurs without limb movement, it is assessed as grade 1. If muscle contraction and joint movement are present but the limb cannot be lifted and can only move horizontally, it is considered grade 2. If the patient can lift the limb off the bed surface and resist some resistance, it is usually classified as grade 3. Since comatose patients cannot cooperate with these maneuvers, muscle strength testing cannot be performed.
Comatose patients require careful nursing care. For example, monitor urine output, urination patterns, and changes in urine color, and promptly report any abnormalities to the physician. Additionally, under medical guidance, assist in regularly cleaning the patient's mouth to help prevent pulmonary infections.
