early pregnancy Flashcards
prevalence of ectopic pregnancy
1-2% of all pregnancies
ectopic pregnancy accounts for what proportion of maternal death
9-13%
(75% of all first trimester death)
tubal ectopic account for what proportion of ectopic pregnancies
98%
what proportion of women having a TV USS will have a PUL diagnosis
15%
outcomes of pUL
- IUP (viable/nonviable) - 34-40%
- ectopic - 8-14%
- persistent PUL 2%
- failed PUL 44-69%
outcomes of persistent PUL
- nonvisualized ectopic
- resolution (Rx or Spont)
- confirmation IUP
incidence of C-Scar pregnancy
1/2000
incidence of abdominal pregnancy
1/5000
incidence of ovarian pregnancy
1/7000
M6 regression model for ectopic - high probable % and management
> =5%
hCG and USS in 48h
M6 regression model for ectopic - low risk EP, probably FPULL management
UPT in 2weeks
M6 regression model for ectopic - low risk, probable IUP; management
USS in 1 week
spontaneous resolution rates for unruptured asymptomatic tubal pregnancies
30-70%
criteria for expectant management of tubal ectopic
1) asymptomatic
2) hCG <1000
3) decreasing hCG >15-20%
4) no significant free fluid, hematosalpinx
5) no FHR
6) patient characteristic
consider active management of tubal ectopic if
- symptomatic
- hcg >=1000
- plateau or increasing hCG over 48h
- large hematosalpinx or hemoperitoneum
- Detectable FHR
consider MTX for ectopic management criteria
- normal obs and no pain
- hCG <1500
- adnexal size <35mm
- empty GS or heterogenous mass
- no free fluid
- hCG <20% increase in 48h
consider single or double dose MTX
use MTX with caution for ectopic management criteria
- mild/transient pain
- hcg 1500-5000
- yolk sac +/- FP
- minimal free fluid
- mild anemia or thrombocytopenia
- hcg >50% increase in 48h
MTX absolute contraindications
- significant renal/liver disease
- blood dyscrasias or bone marrow suppression
- pulmonary fibrosis
- concurrent IUP or BF
- PUD
- immunosuppression
single dose MTX for ectopic, when to check hcg?
day 1, 4, 7, 10, 14
if >=15% drop from day 4, stop protocol and then do weekly hCG until negative
double dose MTX for ectopic, when to check hCG?
day 1, 4, 7, 10, 14
second dose given on day 4
recheck hCG on day 7, if >=15% drop, weekly hCG until negative
multiple dose MTX regimen, when to check hCG
Day 1, 3, 5, 7, 9
if hCG>=15% drop anytime after day 1, do weekly hCG until negative, otherwise proceed with repeat dose
single dose MTX regimen, when to repeat dose?
on day 7
single dose MTX, criteria for failure
- symptoms of rupture
- failure to achieve >=15% decrease after 2 doses
double dose MTX, when to repeat doses?
on day 4, 7, 10
double dose MTX, criteria for fialure
- symptoms of rupture
- failure to achieve >=15% decrease after 4 doses
multi dose MTX, when to repeat doses?
on day 3, 5, 7;
if =<15% decrease in hCG
multi dose MTX - when to give folinic acid
day 2, 4, 6, 8.
multi dose MTX regimen, criteria for failure
- symptoms of rupture
- failure to achieve >=15% decrease after 4 doses
