What are the purposes and precautions of catheterization?

Urinating is an essential behavior of the human body. As people age, their body functions deteriorate, and the failure of organs such as the kidneys will lead to involuntary urination. When this happens, catheterization is needed to help with catheterization. There are also precautions when using catheterization, such as: strict aseptic operation, gentle movements, etc. So what are the purposes and precautions of catheterization? Let me introduce it to you below.

Purpose The purpose of catheterization is: 1. To directly extract uncontaminated urine specimens from the bladder for bacterial culture, to measure bladder capacity and pressure, to check residual urine volume, to differentiate between urinary retention and urinary retention, and to assist in diagnosis. 2. Help patients with urinary retention to release urine to relieve pain. 3. Before pelvic organ surgery, the patient should be catheterized to empty the bladder to avoid accidental injury during the operation. 4. In case of coma, urinary incontinence or perineum injury, retain the catheter to keep the area dry and clean. After surgery for certain urinary system diseases, indwelling catheterization is often required to promote the recovery of bladder function and healing of incisions. 5. When rescuing patients in shock or critical condition, correctly record urine volume and specific gravity to observe renal function.

Notes: 1. Strictly follow aseptic techniques to prevent urinary tract infection. 2. The catheter should be inserted gently to avoid damaging the urethral mucosa. If there is a sense of obstruction during insertion, change direction and insert it again. When urine flows out, insert it another 2cm. Do not insert the catheter too deep or too shallow, and especially avoid repeatedly pulling out the catheter.

3. The thickness of the catheter should be appropriate. For children or those suspected of urethral stenosis, the catheter should be thin. 4. For those with an overfull bladder, urination should be slow to avoid sudden decompression that may cause bleeding or fainting. 5. When measuring residual urine, instruct the patient to urinate on his own first and then catheterize. The residual urine volume is generally 5-10 ml. If it exceeds 100 ml, a urethral catheter should be placed. 6. When indwelling catheterization is in place, the catheter should be frequently checked for fixation and whether it has fallen out. If necessary, the bladder should be flushed once a day with sterile liquid. The catheter should be replaced every 5-7 days, and the urethra should be relaxed for several hours before reinserting.
