21
Q

What are the benefits to doing a spinal for TURP?

A
  1. Bladder will be atonic w/ large capacity.
  2. Postoperative bladder spasm is prevented allowing for hemostasis
  3. Awake patients may supple early detection of complications.
22
Q

What are the two biggest complications of TURP?

A
  1. Blood loss

2. Venous absorption of irrigation fluid.

23
Q

What can venous absorption lead to in TURPs?

A

TURP Syndrom=Water intoxication=Glycine toxicity

24
Q

What are signs of venous absorption during TURP?

A
  1. Early signs= HTN and tachy
  2. CVP may rise
  3. Awake pt= c/o dyspnea or nausea
  4. Leads to hypoxia and/or hyponatremia
  5. Ultimately leads to apprehension, disorientation, convulsions, and coma
25
Q

What three solutions are typically used at irrigating solutions during TURP?

A
  1. Glycine 1.5%
  2. Soribitol 3.3%
  3. Mannitol 5%
26
Q

Which irrigation solution is most likely to cause TURP syndrome?

A

Mannitol

27
Q

Which irrigation solution can cause hyperglycemia and lactic acidosis?

A

Sorbitol

28
Q

Which irrigation solution can cause Transient post-op visual impairment (blindness)?

A

Glycine

29
Q

Which irrigation solution can cause osmotic diuresis?

A

Mannitol

30
Q

Does mannitol lead to hypovolemia or hypervolemia first?

A

Hypervolemia

31
Q

What perop lab is VITAL to obtain prior to TURP?

A

Sodium

32
Q

What is the cutoff for serum Na+ prior to TURP?

A

<125mEg/l

33
Q

What is the treatment for TURP syndrome with hypervolemia and hyponatremia?

A

Fluid restriction and diuretics (lasix 10-20mg)

34
Q

What are the first two steps immediately after diagnosing TURP syndrome intra-operatively?

A

1st. Ask surgeon to control bleeding and finish surgery

2nd. Send blood sample to check serum Na+

35
Q

Which prostatectomy approach has more hemorrhage risk?

A

Retropubic approach

36
Q

Which prostatectomy approaches utilize the supine/trendelenburg position?

A

Suprapubic and retropubic

37
Q

Which prostatectomy approach utilizes the extreme lithotomy position?

A

Perineal approach

38
Q

What post-operative complication is of significance with radical prostatectomy?

A

Impotence

39
Q

What is the frequency of impotence following radical prostatectomy?

A

50%

40
Q

What two things can be caused by methylene blue administration during radical prostate?

A
  1. Hypotension

2. SaO2 drop to 65-85%

41
Q

What affect does indigo carmine dye have on BP?

A

Increase in BP

42
Q

What side effect may the use of the kidney bar have during nephrectomy ?

A

Hypotension and vena cava compression

43
Q

What NMBA should be used on renal transplant recipients?

A

Preferably cisatracurium. Rocuronium has bad renal clearance and succinylcholine may increase serum K+

44
Q

T/F: Regional anesthesia is an excellent choice for renal transplant recipients?

A

False; regional is contraindicated by preexisting coagulopathy and/or immunosuppresision.

45
Q

What type of fluid should be used during a renal transplant case?

A

NS; avoid LR and K+ containing fluids

46
Q

What medications should be used for oliguria with renal transplant recipients?

A

Dopamine and adequate hydration

47
Q

Why might a CVP be specifically helpful for radical cystectomies?

A

Because unable to monitor urine output

48
Q

What are three big complications of radical cystectomies?

A
  1. Hypothermia
  2. Inadequate fluid replacement
  3. Need for post-op ventilation
49
Q

What are typically coexisting medical problems for patients have A/V fistula placed?

A
  1. Anemia
  2. CAD
  3. Diabetes
  4. HTN
  5. Severely out of whack labs
50
Q

What two things intra-op and post-op are vital to helping pass stone fragments following ESWL?

A

Adequate hydration and diuretics
