Q

Anesthesia (general/ spinal)

explain spinal in the purpose of efferent pathways

A

General: acute urinary retention can follow all types of anesthetics or operations due to suppression of
urinary reflex.- inability to sense bladder fullness.General anesthesia induces unconsciousness, Airway Management: Airway control is required in general anesthesia,

Spinal medication: blocks the transmission of the afferent and efferent pathways, unable to sense the need to void, and inability of bladder muscles and urethral
sphincters to respond.
while spinal anesthesia induces regional anesthesia and blocks sensation in specific parts of the body.
whereas spinal anesthesia is administered regionally, targeting specific nerve pathways.but not in spinal anesthesia, where patients maintain spontaneous breathing.

Drugs ( define the classification, 2 drugs DEFINE AND STATE SIDE
EFFECTS)

( remember professor D *cant ……)

state the differences

A

Anticholinergics: HELP TP Decrease MUSCLSE

a.Atropine- used in surgery to decrease secretions (saliva),and increase heart rate.

SE: decreased urgency to void and retention.

b.Glycopyrolate (robinul)- reduces salivary secretions, GI anti-spasmodic, decreases GI motility,
SE: urinary hesitancy and retention

Q

spinal vs epidural

A

Spinal anesthesia is injected directly into the cerebrospinal fluid, whereas epidural anesthesia is administered into the epidural space outside the spinal cord.

Onset and Duration: Spinal anesthesia acts quickly and has a shorter duration of action, while epidural anesthesia has a slower onset and can be prolonged through continuous infusions.

Q

Pregnancy and Childbirth:

Hormonal changes -( relation to bladder muscle)

Muscles- (discuss results)

Trauma- ( give an examples)

Nerve injury - ( which branches)

A

Hormonal changes in pregnancy
cause the bladder muscle to lose tone

Muscles- pelvic floor tissue stretching during
delivery resulting in nerve damage

Trauma- Surgical instrumentation and difficult labor/delivery cause swelling, pain
ex)forceps /vacuum can cause hematoma on baby head

Nerve injury during delivery (afferent nerve

Q

Medications for retention and urgency? 2

A
  1. Cholinergic (urecholine)
    stimulates the bladder to
    contract, which improves
    urine flow (retention)
  2. Anti-cholinergic (ditropan)
    for pts with over active
    bladder. Anti-spasmodic
    that relaxes the muscles in
    the bladder to help decrease
    problems of urgency and
    frequent urination

rebound tenderness

25
a rounded swelling above pubis
pt have absnce of urine. The best way to assess for a distended bladder. This swelling represents the distended bladder rising above the pubis into the abdominal cavity. The client might experience tenderness or pressure above the symphysis
26
Nursing Intervention ( non-invasive) ( 8)
Promote normal voiding: Privacy Comfort Run water Positioning Warm water Crede = pushing down on abdomen Massage spine (S2,3,4 level) Bladder scan
27
bladder decompressions (purpose/ when volume of urine is)
helps decompression of bladder/drain urinary to make it smaller when volume of urine is known to be excessive (>1L), notify provider for guidance r/t gradual bladder decompressio
28
Catheterization (purpose /*4*types)
(invasive) Purpose: Place catheter into the urinary bladder to allow drainage of urine (strict asepsis!!!!) Types of catheters: Straight Retention (double lumen foley) Triple supra *above* pubic / urthera is bypassed Coude
29
Types of catheters: Straight
-Straight catheters are used to drain the Temporary Use: Straight catheters are designed for short-term use and are typically used on an as-needed basis. No Balloon: Unlike indwelling catheters, straight catheters do not have a balloon to hold them in place; they rely on manual insertion and removal.
30
Purpose of catheters ( 6) contd.
To obtain a sterile urine specimen  Measure the amount of residual urine  Empty the bladder prior to surgery  Prevent post op bladder distention  Prevent urine from coming in contact with an incision or open wound/skin breakdown  To obtain accurate intake and output (I&O)  Provide continuous or intermittent bladder irrigation
31

32
Triple lumen
(bladder/prostate sugery pts) - need to retention -clamp it Facilitate continuous bladder irrigation or for instillation of medication. This catheter is primarily used following urological surgery or in case of bleeding from a bladder or prostate tumor and the bladder may need continuous or intermittent irrigation to clear blood clots or debris.
33
Supra | bypasseswhat
suprapubic catheter is a type of urinary catheter that is surgically inserted into the bladder through the abdominal wall, just above the pubic bone. Suprapubic catheterization is often performed when long-term or permanent urinary drainage is required, or when other methods of catheterization (such as urethral catheterization) are not suitable or have failed. | by passes urethera

35
Retention Catheter indwelling/foley
It is held in place by a balloon filled with sterile water, preventing it from slipping out. Foley catheters are commonly used in healthcare settings for patients who are unable to urinate naturally due to various medical conditions or surgeries. Here are the steps for inserting and managing a Foley catheter:
36
Catheter Size  Infants and young children-  Children-  Adults -  Elderly, thin adults-  Large meatal opening -
 French system: the internal diameter of catheter- the larger the number, the larger the lumen size  Infants and young children- 5-8 Fr  Children- 8-10 Fr  Adults 14-16 Fr ( normal 14)  Elderly, thin adults- 12-14 Fr  Large meatal opening -20-30 ( for weak bigger )
37
Retention Catheter Balloon Size Child- Normal size adult- Long term use, post-op TURP, continuous bladder irrigation-
Child- 3ml balloon with 5ml sterile water Normal size adult- 5ml balloon with 10ml sterile water -30ml *Not recommended to pre-test the balloon prior to insertion
38
***Inserting a Urinary Catheter***  Prepare patient- -Female Postioning -Male- Postioing -Pt with issues positions tips:( 3)
1. An indwelling catheter must be ordered by a physician and is inserted only by a licensed nurse. (nursing students can with rn ) 2. Prepare patient- explain 3. Wash hands, gather equipment Female- supine, knees flexed. Tips: need good lighting for visualization Variations in technique bearing down may ease catheter insertion Male- supine, legs straight Pt sims postion with issues.
39
Application of Lubricant Female- Male-
Female- 1-2 (4inches) up the catheter. deep breath Male- up to the Y connector *hold penis at a 90 degree angle 5-7 inchess
40
Maintain Sterile Technique Female Steps ( 3 steps) If catheter is placed in vagina steps
1. Cleansing Labia- 2. Hold labia with non dominant hand- 3.Once hand is positioned, keep in place- DO NOT LET GO! 4.If catheter is placed in the vagina:  Leave it there  Begin with new catheter  NEVER use contaminated catheter
41
urinary stasis
urinary stayed in bladder
42
Male Tips | Catheterizations
cleanse urinary meatus in a circular motion from meatus outwards Hold penis at a 90 degree angle
43
Secure Urinary Catheter | explainpurpose whyyyyyy
Anchor tubing using tape or catheter leg band check tubing. causes infection if not tape to prevent movement.
44
Risks of Catheterization (3)
 Infection- Catheter associated urinary tract infections (CAUTI) account for 80% of hospital acquired infections  Trauma  Reflux
45
Removal of Catheter (6) | think about nurse duties
 Wear clean gloves  Check balloon size  Completely deflate balloon (10ml syringe)  Measure urine output (U/O)  Observe for urinary retention post removal  Assess for signs of UTI (dysuria/frequency/fever/confusion * delrious/dementia )
46
Self or Intermittent catheterization
Single use catheter to drain the bladder Reasons:  Neurogenic bladder  Spinal cord injury
47
Self Catheterization (4)
Goal- empty bladder, prevent UTI  Good vision  Manual dexterity  Cognitive ability ( no dementia)  Motivation
48
Bladder Irrigation Closed System (triple lumen catheter) five steps | DONTFORGET LAST STEP
Irrigation solution and tubing Run in amount of fluid per physician order* Clamp during irrigation (retain bladder) Unclamp to drain irrigant* and urine Subtract irrigant from urine* ( if i have 260 / 60 was irrgaint = my total is 200)
49
Benefits of self catheter (6)
 Decrease in UTI’s  Independence  Decrease in reflux  Normal sexual relations  Release from dribbling  Return to work
50
Closed intermittent bladder Irrigation via specimen port using | state last important step when documenting findings
wash hands cleanse specimen [port with alcohol draw up sterile irrigation solution into 60 ml syringe, connect to specimen port( 10ml) clamp drainage tubing Unclamp drainage tubing and allow irrigant and urine to drain Subtract irrigant from urine total
51
Bladder irrigation– Open System
Physician order/Not recommended
52
Obtaining a Sterile Urine Specimen from a Catheter- ( 6 steps)
1. Clamp drainage bag tubing below the level of the specimen port for 15-30 min 2. Put on clean gloves 3. Cleanse specimen port with alcohol and insert needless access device with a 20-30 ml syringe into self sealing specimen port @ 90 degrees and withdraw urine. 4. Place into sterile specimen container 5. ***Must unclamp tubing 6. Send to lab promptly for analysis per facility policy ( ASAP or it'll get infected)
53
Assessment for retention (4)
- abdominal assessment ( IPP- no A) - assess I&O - bladder scan - used to estimate volume of urine in bladder -palpating the bladder
54
Inserting a Urinary Catheter steps men
Catheterization in Men: **1. Prepare the Patient: Explain the procedure to the patient, ensuring informed consent. Gather necessary supplies: sterile catheter, sterile lubricant, sterile gloves, antiseptic solution, drainage bag, and drapes. **2. Position the Patient: Have the patient lie on their back with knees bent and legs apart, or in a dorsal lithotomy position (similar to a gynecological exam position). **3. Prepare and Cleanse: Wash hands thoroughly and put on sterile gloves. Cleanse the urethral meatus and surrounding area with an antiseptic solution. **4. Insert the Catheter: hold peepee @ 90 degree Lubricate the catheter tip with sterile lubricant. Hold the penis upright, perpendicular to the body. Insert the catheter gently and slowly into the urethra until urine starts to flow. Continue inserting the catheter about 2-3 inches more after urine starts flowing to ensure it is in the bladder. **5. Secure the Catheter: Secure the catheter to the patient's thigh or abdomen using tape or a catheter stabilization device. Connect the catheter to a drainage bag. **6. Ensure Comfort and Safety: Ensure the catheter is draining properly and that the patient is comfortable. Wash hands and provide appropriate perineal care.
55
Inserting a Urinary Catheter steps woman
Insert the Catheter: Lubricate the catheter tip with sterile lubricant. With one hand, separate the labia. Insert the catheter gently and slowly into the urethra until urine starts to flow. Continue inserting the catheter about 2-3 inches more after urine starts flowing to ensure it is in the bladder. **5. Secure the Catheter: Secure the catheter to the patient's thigh using tape or a catheter stabilization device. Connect the catheter to a drainage bag. **6. Ensure Comfort and Safety: Ensure the catheter is draining properly and that the patient is comfortable. Wash hands and provide appropriate perineal care. In both cases, it's essential to use sterile techniques, maintain patient dignity, and ensure proper catheter placement and securement to prevent complications. Proper training and following institutional protocols are essential for performing urinary catheterization safely and effectively.
56
balloon purpose in catheterizations
the balloon in a catheter is essential for ensuring proper placement, stability, and retention inside the bladder. It is a key component that allows the catheter to fulfill its purpose of draining urine effectively and safely. Healthcare professionals carefully inflate and deflate the balloon according to specific guidelines to ensure patient comfort and prevent complications.
57
obtaining specimen
NOT FROM BAG - need to clamp bag ( 15 minutes) -send to labs asap if not refrigerate it
58
Benign prostatic hyperplasia meaning
With this condition, the urinary stream may be weak, or stop and start
59
*REMEMBER THE PURPOSE OF IRRGATION* A client, who had a transurethral resection of the prostate (TURP), has a three-way indwelling urinary catheter with continuous bladder irrigation. In which of the following circumstances should the nurse increase the flow rate of the continuous bladder irrigation? When drainage is continuous but slow. When drainage appears cloudy and dark yellow. When drainage becomes bright red. When there is no drainage of urine and irrigating solution.
3. The decision by the surgeon to insert a catheter after TURP or prostatectomy depends on the amount of bleeding that is expected after the procedure. During continuous bladder irrigation after a TURP or prostatectomy, the rate at which the solution enters the bladder should be increased when the drainage becomes brighter red. The color indicates the presence of blood. Increasing the fow of irrigating solution helps flush the catheter well so that clots do not plug it. There would be no reason to increase the flow rate when the return is continuous or when the return appears cloudy and dark yellow. Increasing the flow would be contraindi-cated when there is no return of urine and irrigating solution. The infusion rate should be increased if the drainage is cherry colored or if clots are seen.
