How to catheterize?

It is imperative that the health care professional has a good understanding of aseptic catheterization procedure principles as this will help to reduce the risk of UTI.

Catheterization with indwelling catheter

  • Protect the patient from surrounding bacteria by keeping the catheter sterile throughout the entire procedure
  • Keep the patient informed about the procedure and make sure that he or she has given their consent
  • It is important to be careful with your own personal hygiene before proceeding

1. Preparations

1.1, Gently pull back the foreskin or separate the labia minora so you can easily access and clean around the urethral opening.

1.2, Anaesthetize the urethra by completely filling it with anesthetic catheter gel. Use 1 gram gel per cm urethra.

  • Amount of gel men: 20-30 g gel
  • Amount of gel women: 5-7 g gel

Wait at least 60 sec until the gel begins to work. Full effect within 5 minutes.

1.3, Follow the manufacturer’s instructions. The BIP Foley Catheter should be pre-wetted to activate the hydrophilic coating.

Change of suprapubic catheter

  • Protect the patient from surrounding bacteria by keeping the catheter sterile throughout the entire procedure
  • Keep the patient informed about the procedure and make sure that he or she has given their consent
  • It is important to be careful with your own personal hygiene before proceeding

1. Removal

1.1, It is preferred that the bladder is as full as possible. Fill the bladder using sterile sodium chloride, maximum 3 deciliter or until the patient feels the urge to urinate.

1.4, To remove the catheter, hold one hand against the patient’s abdomen and gently pull the catheter with the other hand. A small cramp in the abdominal muscle might force you to take a short break in the process. Make sure that the patient is relaxed.

2. Preparations

2.1, To prepare for the new catheter, place a hand on the patient’s abdomen and fill the insertion hole with catheter gel. It will prevent pain as well as lubricate the channel for easier catheter insertion. Let it work a little while.

3. Catheterization

3.1, While you are putting the new catheter in place, observe the patient to make sure he or she does not experience any pain. Be sure to insert the catheter far enough to avoid the balloon from inflating in the abdominal wall.
