Q

How do we manage the third stage of labour to prevent PPH?

A
  1. Administer IV/IM oxytocin after delivery of the anterior shoulder
  2. Immediate skin-to-skin
  3. Delayed cord clamping (1-3 mins)

Q

What assessments/interventions should be done to prevent PPH?

A
  1. Empty bladder
  2. Assess tone + massage fundus PRN
  3. Accurate measurement of blood loss
  4. If bleeding, assess circulatory status

Q

what is considered mild, moderate, and severe shock?

A

Mild - < 20% Blood Loss
–> Diaphoresis, increased cap refill, cool extremities, anxiety

Mod - 20-40% Blood Loss
–> TachyTachy
–> Postural HypoTN
–> Oliguria

Severe - > 40% Blood Loss
–> HypoTN, hemodynamic instability
–> Agitation, confusion

Q

What is considered severe shock from blood loss?

A

Severe - > 40% Blood Loss
–> HypoTN, hemodynamic instability
–> Anxiety/agitation

17
Q

What does a superficial venous thrombosis look and feel like?

A

Similar to DVT
–> Pain, tenderness, warm, red, enlarged or hardened area

18
Q

Why are superficial venous thrombosis less concerning than DVT?

A

Superficial is less likely to dislodge into heart/lungs/cerebral circulation
–> More adherent to venous walls

19
Q

How is superficial venous thrombosis managed?

A

NSAIDS
Rest + elevation
Ambulation
Compression stockings
Heat
Anticoagulant therapy might be indicated

20
Q

Superficial venous thrombosis is most common at what point during pregnancy?

A

Postpartum period

21
Q

When is DVT most common during the pregnancy process?

A

During the pregnancy itself d/t weight of baby

22
Q

How is DVT diagnosed?

23
Q

Why is DVT harder to detect?

A

Redness, warmth will be harder to notice

24
Q

How is DVT treated?

A

IV Heparin
Bedrest, leg elevation, analgesia

With improvement some ambulation, compression stockings and PO warfarin for 3 months

25
Q

How is PE managed?

A

Assess for ABCS + IV Access maintained
–> Treat for shock
–> O2

Immediate continuous IV heparin

26
Q

What are some risks of postpartum infection?

A

Obesity
Concurrent immunosuppression
C/S birth or other operative
Prolonged ROM
Prolonged labour
Internal fetal monitoring

27
Q

What are the four most common kinds of infection in the postpartum period?

A

Endometritis
Wound
UTI
Mastitis (Infection)

28
Q

What is the most common infection during the postpartum period? What are the symptoms and how is it treated?

A

Endometritis
–> Chills, nausea, lethargy, pelvic pain + tenderness, foul smelling lochia
–> IV antibiotics, rest, hydration, pain relief, comfort measures

29
Q

What are signs of wound infections postpartum?

A

Poor REEDA assessment

Treatment: culture site, IV abx, wound care + sitz bath + warm compresses to perineal area

30
Q

What predisposes people to UTI in the postpartum period?

A

Catheterization, pelvic exams, epidural, c/s, personal hx

31
Q

When does infective mastitis usually occur? What are the symptoms? What are the treatments?

A

Usually week 3 or later
–> Flu-like symptoms, local breast tenderness, pain, redness

–> Treat with abx, continue breastfeeding

32
Q

What is the best prevention for postpartum infection?

A

Hand washing, hygiene.

Anticipatory teaching
–> Nutrition, hydration, hygiene, S&S of infection

33
Q

What are the relevant labs when assessing coagulation status?

A

pt, ptt, fibrinogen degradation products (elevated)

Plts, fibrinogen (low)

34
Q

What is a late sign of hypovolemic shock of a postpartum patient?

A

HypoTN - well compensated until severe hypovolemia

35
Q

What veins are affected by superficial venous thrombosis?

A

The superficial saphenous system

36
Q

What veins are affects by DVT?

A

Extend from foot to the iliofemoral region
