Flashcards in peds68 Deck (25):
1

emergency parenteral rehydration

20mL/kg boluses of IV solutions wit a high enough oncotic load to keep it; normal saline or lactated ringers is commonly used

2

if hip Is affected in septic arthritis, it is usually helfd how?

flexion, abduction, and external rotation

3

diagnosis for septic arthritis

elevated WBC, elevated ESR, elecated CRP; culture of synovial fluid pos in only 60% of cases

4

management of septic arthritis

joint aspiration to avoid avascular necrosis and to dx infx; empiric antibiotics for 4-6 weeks to cover gram pos

5

complications of septic arthritis

avascular necrosis and cartilagenous damage

6

transient synovitis

peak age 2-7 years; low grade fever, limp, hip pain

7

most common cause of painful joint in toddlers

transient synovitis

8

management of transient synovitis

NSAIDs, bedrest, and observation

9

Legg-Calve-Perthes

idiopathic avascular necrosis of the femoral head

10

typical patient for Legg-Calve- Perthes

active thin boys who are small for their age

11

clinical features of legg-calve-perthes

slightly painful limp wuth increased internal rotation and abduction of hip

12

diagnosis of legg-calve-perthes

AP and frog lef lateral radiograph of pelvis showing incr density in the affected femoral head and a crescentic subchondral fracture in femoral head (crescent sign")

13

treatment of legg-calve-perthes

physcial therapy and restriction of exercise; surgery if more than 50% damage to the femoral head or if there is movement of the femoral head out of the acetabulum

14

prognosis of legg-calve-perthes

best in younger patinets; less than 9 yo resolve; older develop osteoarthritis as adults

15

slipped capital femoral epiphysis (SCFE)

slipping of the femoral head off the femoral neck

16

typical patient for slipped capital femoral epiphysis

obese adolescent boy

17

clinical features of slipped capital femoral epiphysis

painful limp; bilateral in 30% and patients with hypothyroidism are esp more likely to develop bilat diseasel internal rotation, flex, and abduction are decreased in affected hip

18

diagnosis of slipped capital femoral epiphyses

AP and forgleg lateral radigraphs of pelvis; "Klein line" doesn't cross the epiphysis

19

management of slipped capital femoral epiphysis

pinning the epiphysis to prevent further slippage; don't just place back into normal position

20

complications of slipped capital femoral epiphysis

avascular necrosis and collapse of fem head; chondrolysis; limb length discrepancy; osteoarthritis

21

chondrolysis

degeneration of articular cartilage

22

osteomyelitis

infection of the bone

23

causes of osteomyelitis

staph aureus and strep pyogenes are most common; salmonell and pseudomonas also

24

clinical features of osteomyelitis

fever, bone pain, erytehma, swelling, and induration; painful limp

25

imaging in osteomyelitis

bone scan or MRI; plain radigraph is not good bc it will be normal early on
