Post-operative precautions 1.Post-operative bed time: Patients receive local anesthesia under surgery, no resuscitation and other processes, in addition, the surgical wound is only 8mm, therefore, bed is only to stop the bleeding, two hours after surgery can be free to move. 2. Repeated period (recovery period or edema period): The so-called “postoperative reaction” will start to appear on the third day after surgery, which is manifested by the reappearance of preoperative symptoms or even aggravation, and new symptoms can also appear, such as numbness, pain, soreness and weakness. The duration can be very short or very long, ranging from a few days to 3 months or even longer. About 30% of patients will have various symptoms during the “recurrent period” after surgery, which can be reduced or avoided by strictly following medical advice. The symptoms of the recurrent period are various, but generally they are low back pain, hip pain, numbness, swelling, or soreness at the incision site, etc. A few patients have symptoms on the opposite side, most of them appear or are obvious when standing or sitting, and most of them can be relieved by themselves. If the symptoms are not relieved by bed rest or continue to worsen progressively, the MRI should be reviewed to see if endplate inflammation is present, and the treatment plan should be changed and the treatment period will be extended. Special notice: the “recurrent period” is not a relapse or ineffective treatment, but can recover on its own. The purpose of medication and rehabilitation within 3 months after surgery is to reduce or shorten the recurrent period, but there is no way to make all patients free from the “recurrent period”. 3, imaging changes lag: after surgery, the symptoms improve first, then we can see the MRI, CT and other imaging changes, that is, the so-called “imaging changes lag phenomenon”. The imaging changes are usually after six months, and the factors affecting them are mainly age, length of medical history, whether the patient has received other excessive treatment, prominence, severity of the disease, etc. 4. Contraindications: Do not drink alcohol, do not overwork, and preferably do not eat “hairy foods” such as mutton and seafood for 3 months after surgery. Within six months, do not engage in long-term bending or long squatting work or activities, such as long meetings, grass pulling, etc. Do not lie in bed for a long time after surgery, preferably for no more than 10 hours. Otherwise, the symptoms will be relieved slowly. Within six months, you should not play computer games for a long time, surf the Internet or play cards for a long time, etc. 5. Suggestions: You should keep in touch with the bedside doctor within 3 months after surgery in order to guide the medication and rehabilitation exercises. Medication: It is recommended to use neurotrophic drugs, blood-strengthening drugs, anti-inflammatory and analgesic drugs for 3 months after surgery to facilitate the smooth passage of the “recurrent period”. Follow up: After surgery, you should come back for follow-up at the third month, six months and one year. The follow-up visits include simple questions, physical examinations, imaging examinations, etc. The content of each visit varies and is tailored to each patient’s situation. Each patient should return one year after surgery with preoperative imaging data to review MRI, CT, etc. A review follow-up form should be filled out again one year after surgery for efficacy assessment. Absolutely no bed rest without any exercise after surgery, otherwise there will be adverse consequences Post-operative rehabilitation should be carried out gradually and according to medical advice, and if conditions permit, it should be transferred to the rehabilitation department. Rehabilitation exercises can also be carried out by oneself, such as taijiquan, baduanjin and various gymnastics can be used as exercise programs. If the recurrence is caused by various factors such as poor rehabilitation and improper exertion, you can undergo minimally invasive surgery again, because minimally invasive surgery, unlike open surgery, leaves a lot of scarring that can prevent or make the second surgery more difficult. The second minimally invasive surgery will go as well as the first minimally invasive surgery.
