OSCE Preparation Flashcards
What 2 things should you undertake immediately when you suspect shoulder dystocia?
- Call for help with emergency buzzer and request obstetrician, paediatrician and extra midwives
- Explain to the woman and her partner what is happening
Following calling for help and explaining shoulder dystocia to mum and partner, what should you do next?
Put woman in to McRobers position: Bed flat Legs hyperflexed Pillows behind mothers back removed And apply gentle traction
During a shoulder dystocia emergency, how long should each manoeuvre be attempted for?
30-60 seconds
If McRoberts manoeuvre is unsuccessful during a shoulder dystocia, what should you attempt next?
Apply suprapubic pressure, CPR style, gentle rocking or continuous pressure over fetal back towards fetal chest for 30-60 seconds applying gentle traction
If suprapubic pressure is not successful during a shoulder dystocia, what should you consider?
An episiotomy
Following an episiotomy during a shoulder dystocia, what two things can be attempted next?
Either delivery of the posterior arm or internal rotational manoeuvres
How do you deliver the posterior arm during a shoulder dystocia?
Flex the posterior arm at the elbow, hold the baby’s wrist, gently pull across chest and over face and deliver in a straight line then apply gentle traction to the head.
What are the three different ways to do an internal rotation manoeuvre?
- Pressure on the front of the posterior shoulder and rotate in to oblique diameter
- Pressure on the back of the posterior shoulder and rotate in to oblique diameter
- Pressure on the back of the anterior shoulder and rotate in to the oblique diameter
During a shoulder dystocia, if McRoberts, suprapubic pressure and internal rotation manoeuvres or delivery of the posterior arm are all unsuccessful, what is the final manoeuvre that can be attempted?
Roll woman on to all 4’s and attempt to deliver the posterior (closest to ceiling) shoulder first
You are providing midwifery care to Karis who is a para 1, 41 weeks gestation and is fully dilated and feeling an urge to push. The vertex slowly advances, crowns, but very soon begins to show signs of “turtle necking” and the shoulders fail to appear.
Detail your immediate midwifery management of the situation.
- Call for help using emergency buzzer - ask for obstetrician, paediatrician, extra midwives (obstetric emergency team)
- Explain to the woman and her partner what is happening
- Demonstrate McRoberts position with bed flat, legs hyperflexed and pillows behind mothers back removed. Attempt manoeuvre for 30 - 60 seconds, applying gentle traction
(Manoeuvre is unsuccessful)
- Perform suprapubic pressure CPR style. Gentle rocking or continuous pressure over fetal back towards fetal chest. Attempt for 30-60 seconds and apply gentle traction
- Suprapubic pressure can be combined with McRoberts manoeuvre
(Manouvere is unsuccessful)
- Consideration of episiotomy
- Attempt internal rotation or delivery of posterior arm whilst continuing with McRoberts
- To remove posterior arm, enter the vagina posteriorly, flex the arm at the elbow, hold the baby’s wrist, sweep it across the chest and out in a straight line. Apply gentle traction
(Manoeuvre unsuccessful)
- Attempt internal rotation. Apply pressure to the front of the posterior shoulder and rotate in to oblique diameter or rotate 180 degrees. Try gentle traction
(Manoeuvre unsuccessful)
- Apply pressure on the back of the posterior shoulder and try to rotate in to oblique diameter
(Manoeuvre unsuccessful)
- Try pressure on the back of the anterior shoulder to rotate in to oblique diameter
(Manoeuvre unsuccessful)
- Roll patient on to all 4’s position. Attempt to deliver the posterior shoulder (closest to ceiling) first with gentle traction
Sarah is a 26 year old who is pregnant with her second baby. She is now 38 weeks gestation and is currently in the delivery suite in established labour. Sarah has a breech presentation and has chosen to give birth vaginally. She is now in advanced second stage of labour with the breech slowly descending onto the perineum. The fetal legs are extended and appear to be causing a delay with decent. Explain the midwifery management of this assisted breech birth.
(The legs appear to be stuck)
- Apply pressure behind the knee with the index finger (pressure on popliteal fossae)
(Trunk is now slowly descending until the scapulae are visible but the arms appear to be extended)
- Begin Løveset’s manoeuvre:
- Place towel over baby’s hips to keep warm
- Gently hold baby over the pelvis and turn half circle in a clockwise direction keeping the back uppermost
- The lateral arm is now the anterior arm and can be delivered under the pubic arch
- Place two fingers on the upper part of the arm and draw it down over the chest as the elbow is flexed and sweep over the face
- Turn the baby back a half circle keeping the back uppermost, and deliver the second arm in the same way simultaneously applying downward traction
- It is important to avoid handling the umbilical cord
- Allow the baby to hang until the nape of the neck is visible
(The head does not deliver spontaneously. Demonstrate the next stage of midwifery management)
- Begin Mauriceau Smellie Veit manoeuvre
- Support the baby’s body with non-dominant arm
- The first and third finger of the non-dominant hand should be placed on the baby’s cheekbones with middle finger on the chin
- With the dominant hand, apply first and third fingers to each shoulder and middle finger on the back of the occiput to flex the head
- Apply gentle downward traction to deliver the head in a controlled manner
(Sarah has chosen an active management of third stage)
- Withhold the administration of any oxytocic medication until after the birth of the baby’s head
If the legs are extended during a vaginal breech delivery, what can be done to deliver the legs?
Popliteal pressure (index finger applying pressure behind the knee)
During a breech delivery, if the arms are extended, what manoeuvre can be done to deliver the arms?
Løveset’s manoeuvre:
Place towel over baby to keep warm
Gently hold the baby’s hips and rotate clockwise keeping the back uppermost
Lateral arm is now anterior and can be delivered under the public arch
Place two fingers on upper part of arm and draw it down over the chest, flexing the arm and sweeping over the face to deliver
Turn the baby back a half circle, keeping back uppermost and deliver the second arm in the same way, simultaneously applying downward traction
Take care to avoid handling the umbilical cord
Take hands off again and allow baby to hand until the nape of the neck is visible
During a breech delivery, if the head does not deliver spontaneously, what manoeuvre can be done?
Mauriceau Smellie Veit manoeuvre:
Support the baby on non-dominant arm with first and third fingers on baby’s cheekbones and middle finger on the chin
With other hand, first and third fingers on each shoulder and middle finger on occiput to flex the head
Apply gentle downward traction to deliver the head in a controlled manner
If the woman has requested an active management of the third stage during a breech delivery, when should the oxytocics be administered?
After the birth of the baby’s head
Stephanie has just given birth to a healthy baby girl weighing 4.55kg at home with you and your colleague. Following the active management of the third stage of labour, the placenta and membranes are delivered approximately 8 minutes following the birth of her baby. However, Stephanie continues to bleed heavily. Explain your immediate midwifery management of this.
- Palpate the uterus
(Uterus is boggy)
- Rub up a contraction to try and contract the uterus
(Uterus remains boggy. Blood loss approximately 800mls)
- Request colleague to call ambulance control
- Both me and my colleague must monitor and investigate, resuscitate and stop the bleeding
- Request colleague to administer 2nd dose of oxytocic medication
(Uterus is still boggy)
- Will continue to rub up a contraction and request colleague to check placenta for completeness
(Placenta is complete and uterus still boggy)
- Will continue to rub up a contraction and request colleague to catheterise and empty the bladder
- Request colleague to check for lacerations while catheterising
(No lacerations present, uterus is now contracted and bleeding is minimal)
- Check maternal observations: temperature, pulse, blood pressure and respirations
- Check fundus
- Monitor PV blood loss
- Resuscitate: consider inserting grey venflon
- Commence IV Hartmann’s infusion
- Monitor and investigate: FBC, group and save, clotting screen
(If bleeding did not settle, can you explain bi-manual uterine compression?)
- One hand inserted in to the vagina, locate anterior fornix of the cervix, make a fist. Other hand placed externally on the abdomen, locate the fundus and compress it against the internal fist
