Inserting a Retention (Indwelling) Catheter

Retention (Foley) Catheter Contains a second, smaller tube through out its length on the inside this tube is connected to a balloon near the insertion tip.

Purpose
• To manage incontinence
• To provide for intermittent or continuous bladder drainage and irrigation
• To prevent urine from contacting an incision after perineal surgery (prevent infection)
• To measure urine out put needs to be monitored hourly

Procedure
• Explain the procedure to the patient
• Prepare the equipment like:
Retention catheter
Syringe
├ Sterile water
├ Tape
├ Urine collection bag and tubing

• After catheter insertion, the balloon is inflated to hold the catheter in place with in the bladder.
♦ The out side end of the catheter is bifurcated i.e., it has two openings, one to drain the urine, the other to inflate the balloon.
♦ The balloons are sized by the volume of fluid or air used to inflate them 5 ml – 30 ml (15 commonly) indicated with the catheter size 18 Fr – 5 ml.

• Test the catheter balloon
• Follow steps as insertion straight catheter
• Insert the catheter an additional 2.5 – 5 cm (1-2 in) beyond the point at which urine began to flow (the balloon of the catheter is located behind the opening at the insertion tip) this ensures that the balloon is inflated inside the bladder and not in the urethra (cause trauma)
• Inflate the balloon with the pre filled syringe
• Apply slight tension on the catheter until you feel resistance: resistance indicates that the catheter balloon is inflated appropriately and that the catheter is well anchored in the bladder
• Release the resistance
• Tape the catheter with tape to the inside of a females thigh or to the thigh or a body of a male client

├ Restricts the movement of the catheter and irritation in the urethra when the client moves
├ When there is increased risk of penile scrotal excoriation

• Establish effective drainage
• The bag should be off the floor – the emptying spout does not become grossly contaminated
• Document pertinent data

Removal
• Withdraw the solution or air from the balloon using a syringe
• And remove gently
