1, indwelling urinary catheter care: spinal cord injury in the early stage of spinal shock: (1) every 2 weeks to change the urinary catheter, according to the drinking and infusion of fluids at regular intervals to open the urinary catheter once; (2) every morning and evening to clean the urethral orifice once a day, the male patients pay attention to wash the circumcision dirt; (3) urine bag changed once a day (anti-reflux urine bag can be extended to change the time), the position of the bag should be lower than the knee below the cover, in order to prevent the urine from backward flow of urine back into the bladder (4) keep the perineum dry and clean to prevent moisture caused by buttock redness, eczema, pressure sores, etc.; (5) every 1-2 weeks to check the urine routine, while observing the color and odor of the urine, if there are more flocculent urine and odor, then bladder flushing; bladder flushing can be used simply with 0, 9% saline can also be used with 0,9% saline + gentamicin 2; or with 0, 1 ‰ of iodophor; but bladder irrigation can not be used as a routine means, only when there is a problem with the urine or infection can be carried out; (6) in the indwelling urinary catheter should drink more water, and should record the patient’s urine output. 2.Intermittent catheterization: after stabilization: early intermittent catheterization, urodynamic examination should be carried out to determine the safe capacity of the bladder, compliance, storage pressure, etc., to provide a basis for intermittent catheterization. Principles of intermittent catheterization: (1) adequate bladder capacity: 400-500 ml; (2) good bladder compliance, low bladder storage pressure; (3) no ureteral reflux; (4) normal sphincter function; Contraindications to intermittent catheterization: (1) the patient can’t cooperate (uncooperative); (2) urethral abnormality of the diverticulum; (3) severe UTI; (4) urethral abscess; (5) urethral stricture, bladder neck and bladder neck. Urethral stenosis, bladder neck obstruction, prostate hyperplasia, spasm of the pelvic floor muscles or external urethral sphincter can make catheterization difficult or even dangerous, but it is not a contraindication, and it can be treated by surgical treatment and then continued with intermittent catheterization. Methods of intermittent catheterization: Every 4 to 6 hours, insert the urinary catheter through the urethral opening into the bladder to completely release the urine, and remove the catheter immediately after releasing the urine. Patient education: before intermittent catheterization, patients and their families should be educated about the relevant knowledge: (1) Limit fluid intake: daily fluid intake should be limited to 1500-1800 ml, and required to achieve uniform intake (100-150 ml per hour, including the intake of water in the three meals, if you drink more soups or porridges, then you have to reduce the amount of water, and reduce the amount of water at night); ( (2) let the patient’s family to understand the relevant anatomical knowledge; (3) upper limb good patients as soon as possible to teach self-catheterization method; 3, suprapubic vesicostomy tube care: (1) vesicostomy tube care: open the urinary catheter at regular intervals, (for the patients with severe vegetative nerve dysfunction, should be open for a long time), monthly replacement of fistula tubes once a month; (2) urinary bag changed once a day (anti-reflux bag can be extended the replacement time); (3) urinary bag changed once a day (anti-return bag can be extended replacement time); (4) urinary bag changed once a day (anti-return bag can be extended the replacement time); (5) urinary bag changed once a day; (6) urinary bag changed once a day (anti-return bag can be changed). (3) the position of the urine bag should be lower than the knee; (4) the care of the fistula: the fistula has not grown during the fistula should be 1-2 days to change the gauze around the fistula, to keep clean and dry around the fistula; (5) the rest of the attention to the same as the indwelling urinary catheter. 5, urinary incontinence care After spinal cord injury, with the change of condition, the bladder urethra function also changes, most patients will have different degrees of urinary incontinence, for the incontinence of patients, should first understand the cause of urinary incontinence, the time, leakage of urine or the amount of time; (1) according to the cause of the corresponding treatment, such as overactive bladder caused by leakage of urine, can be taken by mouth shenectin and other M-blocking agent treatment, or Botulinum toxin A injection in the bladder wall and other treatments can improve incontinence; (2) If the incontinence is caused by overfilling of the bladder, the time of intermittent catheterization should be adjusted or the amount of water consumption should be adjusted to control the volume of urine in the range of the safe volume; (3) For male patients, use penile condom or wear diapers; for female patients, pads or diapers can be padded; (4) Pay attention to perineal care for the patients with incontinence, and change the pads in a timely manner, Diapers; wash the perineum with warm water every day, keep the perineum clean and dry, to prevent buttock redness, eczema and other occurrences; (5) such as perineal wounds or sacrococcygeal pressure ulcers in patients with urinary incontinence, should be left in the first urinary catheter to let the wounds or pressure ulcers to heal and then intermittent catheterization.
