Q

hemangiomas- 3 stages

A

girls 3X more than boys- irregular shape, locatized mass of tissue

present at birth 40% of time

rapid growth (proliferative stage)

stability (plateau phase)

regression (involution phase)- occurs slowly approx 10% per year, but spontaneously

30% by 3 years, 50% by 5 years, 70% by 7 years

90% by 9-10 years

Q

goals of treatment

A

goal to decrease psycosocial distress but also avoid agressive treatment for lesions that can resolve spontaneously - stress spont resolution taking time to parents

identify associations with other anomalies

treat ulcerations-prevent disfigurement

prevent life threatingin complications- hemm on mouth/neck might occlude airway

Q

special considerations

A

hemm with lumbarsacral area with tethered cord- refer to neuro surg

hemm on chin- airway- refer to ent

serial eval in young infants, may preceed dev of symptomatic airway

deep hemm- involves deep dermis, bluish nodule

Q

Hemangiomas that req active intervention

A

periorbital tumors- prevent vision damage, astygmatism d/t pressure on globe

involving airway- chin, beard distribution esp during prolif phase

extracutaneous lesions- may conpromise vital structures bc of size, bleeding, rare

causing permanent disfigurement

those in centrofacial area in contours facial skin- also phychosocial distress

Q

systemic propanolol considerations- baseline eval and who needs hospitalization?

A

ongoing debate or need for baseline eval and monitoring during dose escalation

baseline ECG and cardiac exam by exp cardiologist

A

frequent feedings- avoid periods of fasting, BS can drop

18

propanolol education changes in hemm

A

look and feel of hemm may change in days, color change and softer, with reduction in volume in weeks to months

19
Q

propanolol education adverse effects

A

few compared to systemic corticosteriods

Monitor BP - hypotension

bradycardia, resp distress r/t bronchospasm, sleep disturbances, diarrhea, hyperkalemia (which may be associated with seizures)

A
21
Q

A

not first line therapy- lack od standard protocol

prednisone/prednisolone

2-3mg/kg/day

give during most active period of growth in first few months

taper dosing

watch fro adverse effects

22
Q
