What is the purpose of indwelling catheterization What are the nursing measures for indwelling cathe

How acute pulmonary edema occurs.

In the case of preoperative catheterization, it is probably due to the long duration of the operation.

Postoperative catheterization is due to the fact that the anesthesia effect has not subsided, resulting in the failure of smooth muscles and sphincters to contract and relax in time, resulting in urinary incontinence and urinary retention.

The postoperative routine indwelling catheterization of the urinary system can be used to understand the recovery of the postoperative lesion and the bleeding caused by drainage surgery, such as ureteral surgery, and whether the ureter is unobstructed.

Of course, if you have prostatic hyperplasia and urinary retention, then an indwelling urethral catheter is the most direct symptomatic method.

1) Explain to the patient and the family of Zhao Qihuai.

2) Encourage patients to drink plenty of fluids.

3) Maintain the smooth drainage to avoid pressure, twisting and blockage of the urinary catheter.

4) Prevent retrograde infection: keep the urethral opening clean; Regularly change the urine collection bag every day; Change the catheter once a week.

5) When the patient leaves the bed, properly fix the urinary catheter. (6) Train bladder reflex function (7) Urinate routine examination once a week, and bladder irrigation when necessary.

Answer: The case in the clan] :d

One route of infection of the indwelling urinary catheter is retrograde infection of the urine, so the replacement of the urinary catheter is also to prevent the disappearance of the indwelling urinary catheter.

For patients who have been in indwelling for a long time, the main purpose of the need to regularly replace the catheterization tube is ()aExercise bladder reflex function.

b.Allow the patient to rest temporarily.

c.Prevent urinary catheters from aging and breakage.

d.Prevent Retrograde Urinary Tract Infections (Correct Answer).

e.Keep urine draining smoothly.

Disposable catheterization and indwelling catheterization are both catheterization, which mainly refers to the insertion of a catheter into the bladder through the urethra to drain urine. The differences between the two are as follows: 1. The length of stay is different.

One-time catheterization requires catheterization every 4 to 6 hours, and the catheter can be removed once the bladder has emptied. The catheter for indwelling catheterization remains in the patient's body and can only be removed or replaced periodically if conditions allow. 2. The applicable groups of people are different.

One-time catheterization is suitable for patients who are unable to urinate spontaneously after urinary retention and surgery, while indwelling catheterization is suitable for patients who are comatose and urinary incontinence. Whether it is a one-time catheterization or an indwelling catheterization, it needs to be used with good hygiene to avoid infection.
