Q

what is ALARM

A

A systemic approach in managing shoulder dystocia
A: ask for help
L: lift the legs in mcroberts position
A: Apply suprapubic pressure
R : Roll over
M : deliver the posterior arm as a last resort

Q

why does mcrobers position help deliver the baby?

A
  • widens the pelvic outlet
  • alings the pelvic angle and straigtens the sacrum to open the birth canal

Q

why does applying suprapubic presure help deliver the baby?

A

it pushes the shoulder downward, allowing the shoulder to pass under the symphysis pubis

Q

shoulder dystocia is best mannaged with three people, where are all three people placed?

Q

you must record all key events during ALARM. what are you recording?

A
  • time of head delivery
  • time of each maneuver
  • overall outcome
22
Q

rolling over the mom to deliver the baby is known as?

A

gaskin maneuver

23
Q

what does the gaskin maneuver help with?

A

increasing pelvic diameter

24
Q

what position should the mother be in if you are delivering the posterior arm?

A

lithotomy position (lying down) (can be done during the gaskin maneuver

25
what is the definition of breech birth?
the baby is delivered feet or buttocks first
26
complete breech?
buttocks presents first
27
incomplete breech
one or both legs present first
28
frank breech
buttocks presents and legs are extended straight up
29
what are signs of imminent breech birth
- fresh dark meconium - visible buttocks or legs - progression of the buttocks and legs with each contraction
30
why is hands off preformed during breech births?
this avoids stimulating the baby and prevents premature respirations of amniotic fluid, meconium , or other substances
31
once the umbilicus is visble during a breech birth, how much time do you have to deliver the baby?
4 minutes
32
what timmings do you have to document during a breech birth?
- time the umbilicus is exposed - time the hair line is exposed - any time you provide manual assistance
33
what are the indications for the MSV maneuver?
- umbilicus has been exposed for 3 minutes without further progression - hair line is visible
34
when assisting the legs to deliver, what part of the legs are you grabbing?
the popliteal fossa
35
what is limb presentation and what does it indicate?
when a single limb (arm or leg) presents through the birth canal which indicates transverse lie
36
what actions should you take with limb presentation
- do not attempt delivery - encourage panting - wrap the limb with a dry blanket - position the mother in the exaggerated sims position - use gravity to delay labour
37
what are steps for the exaturates sims position?
- place mother on left side - elevate hips using cushions to raise pelvis ubove shoulders - back ar is placed behind for stability
38
why are you choosing to place the mother on their left side during exaturated sims position?
it helps to maintain blood flow to the Inferior vena cava to support maternal and fetal circulation
39
what is a prolapsed umbilical cord?
when the umbilical cord emerges from the uterus ahead of the presenting part of the baby
40
what actions should be taken if there is cord prolapse?
- knee to chest position - exaggerated sims positon - gently replace cord back to the vagina - apply digital pressure to lift parts off the cord
41
what does oxytocin administration do?
stimulates uterine contraction to reduce bleeding
42
what is a retained placenta defined as?
a placenta not delivered within 30 mins post birth
43
indications for uterine massage?
- after the placenta is delivered and the patient is unstable (shock or bleeding) - the uterus is soft and lacks tone
44
what is the goal of uterine massage
- stimulate the uterus to contract - reduce bleeding by promoting uterine tone
45
what are signs for placental seperation
- lengthening of the umbilical cord - increased vaginal bleedng
46
when should you use bi manual compression? what does it help with?
for patients with PPH and an undelivered placenta. it helps to reduce bleeding while awaiting surgery
47
what does urination do post delivery?
- stimulates oxytocin releae - encourages uterine contraction - reduces the risk of hemorrhage
48
how much does the risk of PPH increase if the placenta is not delivered after 30 mins
risk increases 6 fold
49
why does the blood pressure have to be under 160 systolic when administering Oxytocin
because oxytocin can inclrease bloodpressure
