-miscarriage
-
27
Antiphospholipid syndrome
- presence of lupus anticoagulant and or anticardiolipin antibody
- may coexist with SLE
- associated with arterial or venous thrombosis
- pregnancy complications: miscarriage, preeclampsia, fetal growth restriction
28
Tx of antiphospholipid syndrome?
- treat during preggo with heparin.low molecular weight heparin and low-dose aspirin
- if hx of thrombosis: full anticoagulation
29
Acute Renal Failure ARF
- due to preexisting renal disease or pregnancy induced
| - three types: Prerenal, renal, postrenal
30
how do you treat ARF?
- prerenal: restore volume
- renal: treatment is directed at preventing further damage
- postrenal: remove the obstruction
31
What is a worsening prognosis thing for Chronic renal failure?
-serum creatinine greater than 1.5-2
32
What is the most common organism for asymptomatic bacteriuria?
-E. Coli
33
Pyelonephritis
- fever, CVA tenerness, malaise
- elevated WBC and abnormal urinalysis
- 20% of these patients have increased uterine activity and preterm labor
- can result in adult respiratory distress syndrome
34
Tx of pyelonephritis?
- IV hydration
- abx
- antipyretics
- tocolytics if needed
- will need suppression for remainder of preggo
35
What is a common GI thing for Preggo ppl?
-GERD
36
Mendelson's syndrome
- acid aspiration syndrome
- preggo women at greater risk due to delayed gastric emptying and increased intraabdominal/intragastric pressure
- can result in adult resp syndrome
37
Tx of mendelson's syndrome?
