Q

Dev diff in GI sys

A
  • nephrons less mature and effecient
  • glomerular filtration and abs rates low bc kidneys of newborns are immature
  • dec ability to conc urine and reabs AAs
  • loop of Henle shorter which dec ability to reabs Na and water making very dilute urine for first 3M of life
  • H+ excretion red; acid secretion dec, bicarb levels are lower–more vulnerable to acidosis
  • bladder in abdomen until 3-4M
  • vulnerable to electrolyte overload

  • pH 4.5-8
  • Glucose—negative (pos–GN or DM)
  • Protein—negative
  • Ketone—negative
  • RBCs <1
  • WBCs <1 (higher means infection)

Q

Normal serum lab values

A
  • uric acid (2-5.5)–kidneys ability to clear products of metabolism
  • BUN (5-18)

Q

Hypospadias tx goal and management

A
  • surgical repair in stages
  • goals of correction–enable child to void in standing position, fix physical appearance, preserve fxn of sex organ
  • ideal time is 6-18M bc kids don’t realize diff in their body yet

Q

Hypospadias NC

A
  • examine every newborn carefully
  • delay circumcision bc may use foreskin in surg cosmetically
  • psych prep of parent and child
  • postop: pressure dressing (check tip freq, don’t change dressing but check for bleeding), catheter/stent care, double diaper, teach home care
  • avoid tub baths until stent is removed
  • don’t carry baby on hip or ride straddle toy bc don’t want to put pressure on site

Q

Cryptorchidism therapeutic management

A
  • ultrasonography or surgical exploration to locate testes
  • AAP reccs tx before age 1
  • admin HCG (low success)
  • Orchiopexy b/t 6-24M (avoid pressure on site, watch for bleeding)

Q

Obstructive uropathy CM

A
  • recurrent UTI
  • incontinence
  • fever
  • flank or ab pain
  • smelly urine
  • hematuria
  • dysuria
  • polyuria, polydipsia, urgency
  • anemia
  • FTT
  • nocturnal enuresis
21
Q

Obstructive uropathy management

A
  • surgical correct if needed
  • monitor BP
  • may need defect fixed
  • prep for procedure
  • post-op watch
  • protect and care for catheter
  • teach home care (wound and cath care)
22
Q

Vesicoureteral reflux (VUR) and complications

A
  • regurgitation of urine from bladder into ureters and kidneys
  • graded 1-5
  • inc pressure can lead to HTN, renal insufficiency, failure, or scarring
  • primary reflux is familiar and usually outgrown
23
Q

Vesicoureteral reflex types

A
  • Primary reflux–result of incompetent valvular mech at ureterovesical jxn
  • Secondary reflux–from acquired condition like UTI or holding it in
24
Q

signs of VUR

A
  • repetitive UTIs
  • 1 UTI in boys
  • fam hx of VUR (screen early using VCUG)
25
VUR tx
- antibiotics until reflux resolves (long-term course) - grade 4/5 almost always (sometimes 3) get surg; reimplantation of ureter
26
VUR NC, preop
- infx prevention (compliance with abx (best before bed) teach child to empty bladder completely (esp before bed), teach good hygiene - have siblings screened - age appropriate prep for procedures
27
VUR NC post-op
- care for cath and stent - administer analgesics for incision pain and antispasmodics for bladder spasms - teach home care; prophylactic abx for 1-2 post-surg
28
Hernias
Protrusion of a part of organs thru an abnormal opening - danger arises when: protrusion is constricted, circ impaired, interference with fxn or dev of other structures - common herniation areas in kids include (diaphragmatic, ab wall, inguinal canal)
29
Diaphragmatic hernia
Hole in diaphragm that allows ab contents to be sucked up into cavity - severity depends on how early it happened (affects heart more if happens earlier)
30
Congenital diaphragmatic hernia s/s
- s/s often is detected in utero - s/s after birth--resp distress, cyanosis, scaphoid ab, impaired CO
31
Congenital diaphragmatic hernia tx
- intubation - GI decompression - IVF - will need surg ASAP after stabilizing
32
Congenital diaphragmatic hernia surg NC
- monitor resp and fluid, acidosis, thermoreg, cardiac output, sedation, gastric decompression - tube in stomach for decompression - promote bonding and reassurance - postop--continue ventilation (slowly weaned), watch for acidosis, I&O, GI decompression, TPN and liquids, thermoregulation, sedation, pain control, CO
33
Umbilical hernia
Incomplete fusion of the umbilical ring where umbilical vessels exit ab wall - usually ok in 3-5Y - can be fixed in surg but usually not needed (just monitor) - inc in size with cough, bearing down - parents should press down on it and feel air and fluid--go to ER
34
Inguinal hernia
Opening on lower abdominal wall, leaving opening for abdominal contents to poke through - hernia more visible with cry, strain, having BM - need surgery
35
Most important NC for inguinal and umbilical hernia
Press on area and should feel air and fluid; if feel something else, go to ER
36
Urinary tract infection
Bacterial infx including urethritis (urethra), cystitis (bladder), and pyelonephritis (kidneys)
37
UTI epidemiology
- E. coli most causes in females - more common in females bc short urethra - uncircumcised males more likely - very common in kids before age 6
38
UTI risk factors
- constipation - soak in bubble bath (bubbles can irritate urethra) - pinworms - dysfxn voiding; urinary stasis - dec fluid intake - VUR - urologic abnormalities - indwelling catheterizaion - neurogenic bladder (often poor muscle tone, prob with CNS) - sex abuse and intercourse (investigate cause with more than one UTI)
39
UTI CM: infants
- fever - irritable - poor appetite—FTT - wt loss - smelly urine - v/d - cry w/ urination - NOT urgency—can’t discern that
40
UTI CM in kids
- dysuria - freq, urgency, incontinence - foul smelling urine, maybe hematuria - ab pain - fever
41
UTI diagnostics
- urine screening (+ nitrites, + RBCs, + WBCs) - urine culture > 100k colonies of a single bac
42
UTI therapeutics
- cure infx - ID predispose fx (tight underwear, poor wiping, sex activity) - prevent recurrent infx
43
UTI NC
- specimen handling - adequate admin of abx - push fluids - promote comfort - adequate follow-up cultures - teach preventative measures like promote freq bladder emptying, hydration, avoid tight pants, avoid colas and caffeine, chx period products freq
44
Enuresis
involuntary passage of urine by a child over age of 5 - primary or secondary - diurnal or nocturnal
45
Enuresis etiology
Primary - fam tendency - dec bladder capacity (age + 2 in oz) - heavy sleep - nocturnal polyuria theory - dev or maturational lag - sleep dx Secondary - psych fx (divorce, bully) - abuse - UTI - diabetes - sickle cell anemia
46
Enuresis dx/tx
- hx and physical - urine sample (check for UTI) - hx of bed wetting - wait for maturation (most kids outgrow by age 10) - tx the cause - retention/control exercise - drug therapy: oxybutynin, imipramine, DDAVP for special situations like sleepovers ($$$) - moisture alarm--beeps or vibrates - behavior mods--positive reinforcement is key
47
Enuresis NC
- don't punish child - child not lazy or doing on purpose - recc books (Dry ALL night, waking up dry) - limit choc and caffeine - limit fluids after dinner - use bed pads and 2 sets of sheets - use pull ups only on sleepovers--wick moisture away but we want kids to get used to getting up after feeling moisture - void schedule and gradually inc to get kids used to peeing not in bed - teach use of alarms - support and encouragement
48
What is normal urine output
1-2 mL/kg/hr
49
Desired urine pH
4.5-8
