Study These Flashcards
A

Group A strep

25
What is the commonest organism causing puerperal sepsis caused by mastitis or wound infections?
Staph aureus
26
Prophylactic antibiotics are given before a C-section to reduce the risk of which infections?
Endometritis and wound infections
27
Offensive smelling bloody discharge and abdominal pain after delivery suggests that what complication has developed?
Endometritis
28
In women with puerperal sepsis, broad spectrum IV antibiotics are given within one hour of presentation to hospital. What combination of antibiotics is most commonly used?
Co-amoxiclav and metronidazole
29
Why does pregnancy cause reduced blood flow, contributing to the increased risk of VTE?
Compression of the iliac veins by the gravid uterus
30
What medication is given to women who are deemed high-risk of developing VTE both during and after pregnancy?
LMWH
31
Pregnant women are more likely to develop pelvic DVT. This causes what symptom?
Lower abdominal pain
32
What investigation is carried out first in women with signs and symptoms of DVT or PE?
Lower limb Doppler
33
If a lower limb Doppler is negative but a PE is still suspected, what is the next investigation to order?

34
After a CXR for a woman with a suspected PE, one of which two investigations can be used next?
V/Q scan or CTPA
35
What are the advantages of using CTPA over V/Q scan in pregnancy?
More accurate and less radiation to the foetus
36
What is the disadvantage of using CTPA over V/Q scan in pregnancy?
Increased risk of breast cancer in the mother
37
What blood tests must be done before treatment with LMWH, as the results are used to determine the dose?
FBC (for platelet count), U&Es and LFTs
38
Why is a measurement of D-Dimer an unhelpful test in pregnancy?
D-Dimer is always increased in pregnancy
39
When should LMWH be given in a pregnant women with suspected VTE?
ASAP (i.e. don't wait for investigation results)

What medication is used to treat VTE in pregnancy?
LMWH
41
What medication is used to treat VTE in the post-natal period, even in breastfeeding women?
Warfarin
42
How are women with a massive PE causing maternal collapse treated?
Unfractionated heparin or thrombolysis with IV streptokinase
43
For women who have a DVT in pregnancy/post-natally, what should be given to them to help prevent post-thrombotic syndrome?
Anti-embolism stockings
44
How long should anti-embolism stockings be worn for after treatment for VTE?
2 years
45
After delivery, maternal shortness of breath and hypoxia followed by maternal collapse should point you to what diagnosis?
Amniotic fluid embolism
46
