Spinal endoscopic surgery is a minimally invasive orthopedic technique. Before performing spinal endoscopic surgery, patients and their families need to be well prepared. Tips: 1. Patients should stop smoking and drinking 1 week before surgery, and start training to urinate and defecate in bed 2-3 days before surgery. 2. 1-2 days before surgery, train side or prone lying and gradually extend the time of side or prone lying until you can insist to 1-2 hours. The surgeon should determine whether the patient is comfortable in lateral or prone lying and whether there is any breathing disorder before surgery. If the surgery is performed under local anesthesia, this training is even more necessary. 3.Defecation should be unobstructed to treat intestinal cavity distention and constipation, otherwise it will seriously affect the effect of C-arm X-ray machine fluoroscopy which is necessary for intraoperative operation. 4.Stop taking blood-activating and other drugs before surgery. Such as salvia, red ginseng, etc. Patients who take aspirin need to stop taking the medication for 5 days before arranging the surgery. 5, 1 day before surgery, should clean the whole body and change clothes, but should avoid cold, etc. 6.Fast drinking and fasting for 6 hours before surgery, and emptying stool and urine half an hour before surgery. 7.If the operation is estimated to take a long time, a catheter should be left in place to prevent overfilling of the bladder during the operation. 8.Pre-operative prophylactic application of antibiotics, cross-matching of blood specimens and preparation of blood according to surgical needs for use during surgery when necessary. 9.30 minutes before surgery, give preoperative medication as prescribed by the anesthesia doctor. 10.Give appropriate sedative drugs, such as oral diazepam 5mg, to patients with excessive emotional tension before surgery to ensure that patients get good rest before surgery. 11.Before entering the operating room, remove dentures, watches, earrings and other things and keep them properly; prohibit makeup to avoid affecting the intraoperative observation of the condition. 12.Patients should be equipped with a suitable waist brace before surgery and bring it into the operating room, and put it on immediately after surgery. It is better to have a tight waist brace than a loose one, and it is better to have a hard one than a soft one. 13. Bring medical records, various related imaging materials, intraoperative medications and other items into the operating room with the patient.
