Postpartum Hemorrhage (PPH)
•From delivery up to 6wks postpartum
•SVD Spontaneous vaginal delivery: greater than 500ml (considered PPH)
oEstimated blood loss
oQuantitative blood loss (weighing everything)
•CS C-Section: greater than 1000ml
Two main reasons for PPH
•Full bladder
•Retained placenta
What you will assess when you walk into a patient’s room for PPH
1. Assess Fundus
-should always be right at umbilicus
If it feels like your cheek: boggy; (massage it) Don’t stop unless it firms up
2. Call for help
3. Call Dr.
4. Meds
5. VS and O2 stat
6. Weigh under pads (add this amount of blood loss to what she lost at delivery
7. Change under pads
8. Empty bladder (foley)
9. Start 2nd IV; may need to give patient blood
oOnce you start to feel the fundus firm up you can stop massaging
oOnly thing that can misplace the fundus is a full bladder
•The uterus has to contract to stop bleeding
Meds (all usually standing orders)

We’re always going to look for variability It’s the babies hear beat from beat to beat Absent- 0 BPM Minimal 0-5 BPM Moderate 5-25 BPM—Always want Marked >25 BPM Characteristics of contractions:
  • Coordinated o Frequency ▪ Beginning of one uterine contraction to the beginning of the next ▪ Range in minutes; how often (ex. 1.5- 2 minutes)

DOWNLOAD TO SCORE A

▪ Don’t want a frequeny to be any more than 2 min’s lasting about 60- 90 sec’s o Duration ▪ Beginning of a uterine contraction to the end of the same contraction when it comes back to baseline ▪ Range in seconds; how long is last (ex. 60-90 sec’s)

  • Involuntary
  • Intermittent- relaxation of the contraction (we must have this relaxation period, because if not. That means the uterus is not contracting & it’s where the fetus is getting most nutrients & oxygen. During that resting tone) Contraction Cycle o Increment ▪ Period of increasing strength o Acme ▪ Period during which the contraction is most intense

Fetal Heart strip

  • Baby heart tone always at top
  • Mom contractions at the bottom Variable (type of deceleration) Cord Compression -Sudden drop with a quick return to baseline -Reposition mom w/in 30 seconds. V or W appearance Early (starts right w/contraction) Head Compression (usually est. 8cm) -mirrors mom contraction -Sterile vaginal exam (find out dilation)
  • reposition mom Acceleration (above baseline)-lack of baseline Oxygenated -Baby is saying he is ok

Late (declaration and contraction don’t match) Placental insufficiency -Baby suffering -Not getting enough oxygen & nutrients Characteristics of late- beginning, middle, & end are off LATE deceleration (what to do)

  1. Reposition mom
  2. Shut off Pitocin (causes contractions)
  3. Increase IV fluids
  4. o2 via nonrebreather mask (8-10/L)
  5. Sterile vaginal exam-
  6. Call provider *Anything goes below baseline; deceleration *Want to see lots & lots of acceleration (when baby moves HR should go up) *NEVER nasal cannula in L&D Accelerated Increase in fetal heart rate
  • 15 beats by 15 beats above baseline (32+weeks)
  • 10 beats by 10 beats above baseline (under 32 weeks) Fetus well oxygenated Uterine body

- Cephalic Presentation

  • The cephalic presentation is more favorable than others for the following reasons:
  • • The fetal head is the largest single fetal part, although the breech (buttocks), with the legs and feet flexed on the abdomen, is collectively larger than the head. After the head is born, the smaller parts follow easily as the extremities unfold.
  • • During labor, the fetal head can gradually change shape, molding to adapt to the size and shape of the maternal pelvis.
  • • The fetal head is smooth, round, and hard, making it a more effective part to dilate the cervix, which is also round.
  • Cephalic presentation has the following four variations (Fig. 12.8):
  • • Vertex—This is the most common type of cephalic presentation, in which the fetal head is fully flexed. It is called a vertex or occiput presentation and is the most favorable for normal progress of labor because the smallest suboccipitobregmatic diameter is presenting.
  • • Military—The head is in a neutral position, neither flexed nor extended. The longer occipitofrontal diameter is presenting.
  • • Brow—The fetal head is partly extended. The brow presentation is unstable, usually converting to a vertex presentation if the head flexes or to a face presentation if it extends. The longest supraoccipitomental diameter is presenting. C-section
  • • Face—The head is extended, and the fetal occiput is near the fetal spine. The submentobregmatic diameter is presenting. C-section
