Lumbar disc herniation, also known as lumbar leg pain and spinal nerve compression, is a common chronic degenerative lesion in neurosurgery, and patients mainly present with symptoms of spinal nerve compression. Currently, both neurosurgery and orthopedics can perform surgery for lumbar disc herniation, but in comparison, neurosurgery is more advantageous in terms of nerve protection and relief of nerve compression. Patients need to know the following after admission: Postoperative instructions: 1. Postoperative position: bed rest for 3 to 4 weeks, nurse to assist patients to turn every 4 to 6 hours after surgery to avoid pressure sores. 2. General care: closely observe changes in patients’ vital signs and incisional exudate to prevent hemorrhage and cerebrospinal fluid leakage, focusing on the recovery of sensory-motor function of both lower limbs. 3. Reasonable diet: enhance nutrition and prevent 4. Functional exercise: early postoperative straight leg raising exercises to prevent nerve root adhesions. During the period of bed rest, you can cooperate with the exercise of limb activities. Discharge instructions: 1. Sleep on a hard bed after discharge. Patients can leave the bed if their condition allows, but should not be too long, not too much weight, squatting when lifting and picking things, avoiding lumbar bending weight. 2, diet should be light, cautious of fried food, eat more high-protein, low-fat, high-calorie, high-fiber food, to ensure nutrition and prevent constipation. 3, recovery period to maintain the correct standing, walking, sitting and labor posture, to maintain the lumbar region, 4.Patients who underwent simple lumbar disc herniation removal gradually leave bed after three weeks and continue to wear a lumbar girth for about 3 months; patients who underwent lumbar disc herniation removal plus internal fixation gradually leave bed with a brace after one month and continue to wear a brace for about 3 months. The brace and lumbar girth were taken off at bedtime. And try to use it to protect the waist when sitting and bending with weight. 5, pay attention to avoid cold and keep warm. In winter, pay special attention to the warmth of the waist and both lower limbs. In summer, we should pay attention to the room temperature can not be adjusted too low, especially pay attention to the back of the waist can not blow against the cold wind. 6, strengthen the exercise of the muscles of the back and legs to increase the stability of the spine. However, attention must be paid to the gradual progress, not too hasty.7. Actively participate in appropriate physical exercise to enhance physical fitness.8. Review after 2-3 months, according to the recovery to determine the time to work, generally brain workers can resume work in about 2 months after surgery, manual workers must gradually start working in 3-4 months. Avoid strong bending and weight-bearing activities.
