light sensory test

The shallow sensory examination refers to the examination of abnormal pain, temperature and touch of the skin and mucous membranes. If the patient's state of consciousness is poor and must be checked, the patient's response to the test stimulus is only roughly observed to estimate the state of the patient's sensory function. Such as sputum, facial painful expression or retraction of stimulated limbs. Pay attention to the two-sided comparison and the near-far comparison when checking. It can be gradually moved from the sensory disorder area to the normal area, and if it feels allergic, it can also be moved from the normal area to the obstacle area. Basic Information Specialist Category: Skin Examination Category: Other Inspections Applicable gender: whether men and women apply fasting: not fasting Tips: Before you check, you should prepare the needle, cotton or cotton wool to be used. Patients with spontaneous pain on the skin are not eligible for this test. Normal value 1, pain test normal people feel normal pain. 2, temperature sense check normal people can identify the temperature difference of 10 ° C. 3, tactile check normal people are very sensitive to light touch. Clinical significance Abnormal result 1. If the pain test is local pain, the inflammatory lesion affects the peripheral nerve of the part. In the case of burning pain, it is seen in incomplete sympathetic damage. 2, temperature dysfunction is seen in the spinal thalamus side bundle damage. Such as suspected patients with damage to the lateral side of the spinal thalamus. 3, the tactile dysfunction is seen in the posterior cord lesion. People who need to be examined have patients with shallow sensory disturbances. Precautions Contraindications before inspection: Prepare the needle, cotton or cotton wool to be used before inspection. Requirements for inspection: 1. When examining the sensory function, the patient must have a clear consciousness and the examiner's attitude should be harmonious. Before the patient should explain the method, purpose and significance of the examination patiently, in order to obtain the full cooperation of the patient. But there can be no hints. 2, the environment should be quiet when inspecting, requiring the patient to close the eyes, it is best to check if the patient has no spontaneous pain. 3, pay attention to the two sides of the comparison and far and near comparison. It can be gradually moved from the sensory disorder area to the normal area, and if it feels allergic, it can also be moved from the normal area to the obstacle area. 4. When you find a sensory disorder, you should pay attention to the extent, nature and extent of the disorder. It should be checked and verified repeatedly to make detailed records or illustrations for future observation and comparison. 5. If the patient's state of consciousness is poor and must be checked, only the patient's response to the test stimulus is roughly observed to estimate the state of the patient's sensory function. Such as sputum, facial painful expression or retraction of stimulated limbs. Inspection process 1. Algesia usually uses the tip of a pin to puncture the patient's skin with a uniform force, allowing the patient to immediately state the specific feeling. In order to avoid subjective or suggestive effects, patients should be closed for testing. During the test, pay attention to the comparison of the bilateral symmetrical parts, and record the type of sensory disturbance (normal, allergy, decline, disappearance) and range after the examination. In the case of local pain, the inflammatory lesion affects the peripheral nerve of the part. In the case of burning pain, it is seen in incomplete sympathetic damage. 2, before the temperature sense check must first prepare the cool water and hot water to be used, cold water is 5 ° C ~ 10 ° C, hot water is hot water 40 ° C ~ 50 ° C. When checking, let the patient say whether it is hot or cold water that touches his skin. 3. When the tactile examination is performed, let the patient close his eyes, touch the skin with cotton wool or feathers, ask him to answer the feeling, and if there is no feeling, it is a tactile disorder. Not suitable for the crowd Inappropriate population: Patients with spontaneous pain in the skin. Adverse reactions and risks Nothing.
