What are some reasons for catheterization?
- Relieving urinary retention.
- Obtaining a sterile urine specimen.
- Obtaining a urine specimen when usual methods can't be used.
- Emptying bladder before, during, or after surgery.
- Monitoring critically ill Pts.
What is a intermittent urethral catheter used for? (straight catheters)
Who usually uses straight catheters? How many lumen(s)?
To drain the bladder for shorter periods.
Pts w/ spinal cord injuries or other neurologic conditions.
For the intermittent catheter, is a clean or sterile environment recommended (technique)?
When is an indwelling urethral catheter used?
(retention or foley catheters)
What are they used for? How many lumens and what are they used for?
What type of technique is used for an indwelling catheter?
When the catheter is to remain in place for continuous drainage.
- To decompress and over-distended bladder.
- Intermittent bladder drainage and irrigation.
- Continuous bladder drainage.
2 lumens: 1 for drainage the other for irrigation.
Sterile technique used for indwelling cath.
What is the purpose of the inflated balloon in an indwelling, 2 lumen catheter?
Which catheter is preferred for long-term use?
So that it does not slip out of the bladder.
Suprapubic catheters are preferred over indwelling catheters for long-term use.
How is a double-lumen cath different from a triple-lumen cath?
(foley/retention vs suprapubic)
Double: one lumen connects to the balloon, the other lumen is where the urine drains.
Triple: additional lumen used for instillation of irrigating solution.
When is a suprapubic catheter used?
For what types of situations?
How many lumens does the suprapubic catheter have and what is each lumen used for?
For long-term continuous drainage.
When injury, prostatic obstruction, or gynecolgic or abdominal surgery has compromised the flow of urine.
3 lumens: 1 for drainage, 1 for inflating the balloon, and 1 for instilling medication.
