What is urinary catheterization?
|
Placement of a flexible tube through the urethra into the bladder.
|
|
|
What is the primary purpose of catheterization? What are some other reasons?
|
The primary purpose is to remove urine from the bladder. Other reason may include: infusion of fluids into the bladder
|
|
|
Give an example of when fluids may be infused into the bladder?
|
A male pt. who undergoes a surgical procedure called transurethral resection of the prostate may often have postoperative bleeding and may need bladder irrigation.
|
|
|
Name some types of catheters.
|
Intermittent, indwelling, and suprapubic and urethral/ureteral stents.
|
|
|
What is a intermittent catheterization?
|
The insertion of a single lumen catheter to drain the urine in the bladder which is then removed upon emptying.
|
|
|
What is a fem-cath?
|
A type of intermittent cath. used to obtain a sterile urine sample from a female.
|
|
|
What are some nursing actions for intermittent catheterizations?
|
Assessment, insertion of the catheter, measurement of the urinary output, obtaining lab specimens, removal of the cath and documentation.
|
|
|
What is an indwelling catheterization?
|
Insertion of a double or triple lumen catheter that is used for continuous bladder drainage, monitoring of urinary output or for CBI.
|
|
|
What are some other names for intermittent catheters?
|
Straight cath, in-and-out cath, & Fem-cath (type of intermittent)
|
|
|
What are some nursing actions for indwelling catheterizations?
|
assessment, insertion of cath., monitoring of urinary output, CBI, catheter care, irrigation, obtaining lab specimens, removal of cath and documentation.
|
|
|
Explain how a double and triple lumen catheter works.
|
A double lumen cath. has two passages one which is for urine drainage and another which goes from a one-way valve on the proximal end of the cath. to a balloon on the distal end which "anchors" the cath in the bladder. The triple lumen cath. has a thrid passage through which saline can be infused to irrigate.
|
|
|
What are suprapubic catheters?
|
catheters inserted by a physician percutaneously through an incision just above the pubic bone.
|
|
|
When would a suprapubic cath. be used?
|
When a catheter cannot be inserted through the urethra or when urine is not able to flow normally (eg.: pts with strictures, benign prostatic hyperplasia, injury or surgery)
|
|
|
What are some nursing actions for suprapubic catheterization?
|
assessment, measurement of output, cath. care, irrigation, obtaining lab specimens, and documentation.
|
|
|
What are some reasons a physician may order urinary catheterization?
|
1. pt. is unable to complete bladder emptying.
2. pt. cannot provide urine specimen for lab (altered mental state, comatose, etc.) 3. To obtain a sterile lab specimen. 4. To check PVR 5. drainage before or after surgery 6. monitoring the status of pt. |
|
|
What is a PVR and how is it done?
|
Post-Void residual. It measures the amount of urine remaining in the bladder after voiding. The pt. is asked to void normally, then a intermittent cath. is inserted to measure amount of urine remaining in bladder.
|
|
|
What are some risks to catheterization?
|
Infection, trauma from too much force on insertion, or trauma from inflation of balloon if not if all the way into the bladder.
|
|
|
What are some ways to decrease risk of infection with indwelling catheters?
|
Using sterile tech. to insert cath. and proper care and cleaning of cath.
|
|
|
When is irrigation used?
|
Intermittently to ensure patency of lumen or continuously when there is bleeding or a risk of clots that could occlude the catheter.
|
|
|
What types of things would a nurse monitor when assessing a pt. with a catheter?
|
monitor: odor, color, clarity, quantity, and signs/symptoms of UTI or sepsis.
|
|
|
How often would output of urine be monitored on a pt. with a catheter?
|
Depends on the health status of the pt. Some may need monitoring every 4-8hrs. while others may need monitoring every hour.
|
|
|
What additional I & O consideration is need whith a pt. who have a CBI?
|
These pts. will have irrigation therefore the amount of bladder irrigant that is infused must be added to the intake amount and therefore substracted from the total output to determine the amount of urine produced.
