Shoulder Dystocia Flashcards
Definition
Vaginal cephalic delivery requiring additional obstetric manoeuvres to delivery fetus shoulders after delivery of head and gentle traction failed (RCOG, 2012).
TIME CRITICAL EMERGENCY
Incidence
0.1% - 3% of all births. 50% of cases have birth weight below 4000g
Risk factors
- Previous shoulder dystocia
- Macrosomia > 4000g
- Gestational age
- GDM
- Obesity BMI > 30
- Prolonged 1st/2nd Stage
- Operative vaginal birth
Help
Senior Midwife - Aware of ward activity Senior OBS - Experienced and knowledge Anaesthetist - In case we need to go theatre Scribe - To document everything Paediatric - To assess baby condition Runner - To get equipment
Recognition
- Prolonged crowning/restitution
- Prolonged head bobbing
- Difficulty with birth of face and chin
- Turtle neck sign, chin retracts and depress perineum
Principle management
- Maximise pelvic dimension space for shoulders
- Adduct shoulder
- Change alignment of shoulders to pass through widest diameter of pelvis
McRoberts position
- Lay women flat
- flex hips and knees to chest and apply axial traction to fetal head to assess if successful
Increases AP diameter, flattens sacrum and flexes fetal spine
All fours position
Position women in exaggerated in all fours to increase pelvic diameter
Suprapubic pressure
- Apply pressure from side of fetal back which reduces diameter of shoulders by adducting shoulders
- Apply pressure above symphysis pubis onto posterior aspect of anterior shoulder using CPR grip
Apply axial traction
Episiotomy
To aid in internal manouvres
Internal manouvres
- Delivery of posterior arm
- Internal rotational manouvre
Delivery of posterior arm
- Reduces diameter of fetal shoulders
- Pringle hands into vagina
- Feel for hand and forearm, take hold of wrist with fingers
- Release posterior arm in straight line
- Once arm delivered apply axial traction
- If arm across body, flex antecubital fossa and grab wrists
Internal rotational manouvres
- Move shoulders out of the narrowest diameter into widest diameter
- Pringle hands press on anterior or posterior aspect of posterior shoulder
- Rotation moves shoulder into wider oblique pelvis and perform axial traction
- If one direction doesn’t work try opposite direction
Additional manouvres
- Performed by consultant
- Deliberate clavicle fracture with direct upwards pressure on clavicle
- Zavanelli manouvre, cephalic replacement by C/S
- Symphysiotomy, division of symphysis pubis
Aftercare
- Active management of third stage
- Psychological care, perform debreif
- Perform resus, skin to skin, early feed, cord gases, Vit k
- Maternal normal post labour observations
