Q

Management of AGUS and HSIL

A
  • If 1 abnormal smear of AGUS or HSIL (= CIN II, CIN III, or CIS), you must refer to colposcopy!!

- Look at lycor volume
- Doppler through umbilical artery (incr. resistance will bounce blood off placenta)

_Eclampsia _

Management (worry about mom not baby)
- ABC (establish 2 large bore cannulas)
○ Pulse oximeter, O2
- Restrict IV fluid to 80 ml/hr (can cause pulmonary edeam), like to see 30 ml output/ hr - monitor input and output
- Place mom in LL position
- Prevention: MgSO4 4g over 15 minutes (IV load) then 1-3 g/hr for next 24 hour (prophylactic >160/110 or symptoms of pre-eclampsia then start)
○ Therapeutic range: 2-4 mmol/L (check reflexes)
§ 1 g IV slow (over 3 min) infusion Ca gluconate if too high

  • BP: goal 90-110 maternal diastolic
    ○ If BP 160/110: IV labetalol or IV hydralazine
    Post-partum management
