Q

Placenta accreta ?

A

A decidual layer normally separates the placenta villi and the myometrium. When there is no decidua, it is termed placenta accreta vera.

**if it does not peel off it just never stopped bleeding and this leads to hysterectomy **

Q

Placenta accreta pathophysiology ?

32
Q

Manual removal of placenta if ?

A

If not spontaneously delivered by 18-30 mins

33

careful cause you can cause more bleeding and give the prophylaxis ABS **

34

37
Q

Control of persistent bleeding: Bimanual compression and massage ?

A

For atony

May need 20-30 minutes

Foley should be in place cause she needs to be diuresing

Control of persistent bleeding: Curettage ?

A

If massage not helpful

Risk of perforation, increased bleeding

Risk of scarring, adhesions(Asherman’s syndrome)

39
Q

Control of persistent bleeding: Intrauterine pressure ?

A

Packing no longer done ( cause TSS)

Use inflatable balloon instead

40
Q

Control of persistent bleeding: Uterotonic agents ?

A

Oxytocin

41
Q

Control of persistent bleeding: Radiographic embolization of pelvic vessels
?

A

Interventional radiologist

Angiographic technique

Fluoroscopy guided – gelfoam into damaged vessel

Helps to maintain fertility (low # cases so far)

Helps to avoid hysterectomy

Risk of loss of circulation to legs, labia, buttocks with necrosis

42
Q

Uterine inversion patho ?

A

Prolapse of the fundus to or through the cervix

43
Q

Uterine inversion prevalence ?

A

1 in 2000 deliveries

44
Q

Uterine inversion RF ?

A

Placental implantation in fundus

Partial placental accreta

Weakened myometrium

Prolonged labor

Strong traction on umbilical cord

Fundal pressure - gentle massage

Hx of uterine inversion

45
Q

Uterine inversion Dx ?

A

Diagnosis is obvious – red-blue bleeding mass at the cervix, in the vagina or outside the vagina

Depressed or absent fundus

Shock, hemorrhage and pain

46
Q

Uterine inversion complications ?

A

Depends on degree of hemorrhage and how quickly and how effectively treated

Endomyometritis frequently follows

Mortality is low since usually promptly recognized and treated

47
Q

Uterine inversion Tx. ?

A

Fluid and blood replacement for hypovolemic shock

Manual repositioning of uterus

With or without IV tocolytics to relax uterus (mag sulfate or terbutaline)

After repositioned – prostaglandins for uterine contraction

Antibiotics

Rarely is surgery required

48
Q

Postpartum infections prevalence ?

A

2-8% of postpartum females

49
Q

Postpartum infections sxs. ?

A

Fever is hallmark, but not necessary

50
Q

Postpartum infections RF ?

Long labor

Multiple pelvic exams

51
Q

Postpartum infections examples ?

A
  • Endometritis
  • UTI

Pneumonia

Caesarean section wound infection

Episiotomy infection

52
Q

Endometritis patho ?

A

Vagina normally has pathogenic flora

Protective factors

  • Acidic pH
  • Thick cervical mucous
