Dystocia means difficulty in labour
• Shoulder dystocia means difficulty in delivery of the shoulder
• Mostly the anterior shoulder gets stucked behind the symphysis pubis
Risk factor
• Maternal diabetes (lot of insulin results in lots of fat deposition)
• Macrosomic baby (more than 4 kg)
• Maternal obesity
• Prolonged labour
• Induced labour
• Instrumental delivery
• Post maturity (beyond 42 weeks)
• Previous history of shoulder dystocia
• Multiparity (specially grandmulti)
Identify the risk factors
Q. A 33 Year old, G7P6 , at 39 weeks undergoes induction of labour i/v/o Gestational hypertension. Her previous pregnancies ended up in uneventful normal vaginal deliveries. BP – 160/96 mmHg. Her pre pregnancy weight was 115 kg and she has gained 13.5 kg in present pregnancy. The estimated fetal weight is 3.5 kg.
• 22 hours after labour induction and 2 hours after pushing, the fetal head delivers and retracts at the perineum. Gentle traction fails to deliver the anterior shoulder.
Ans. A 33 Year old, G7P6 , at 39 weeks undergoes induction of labour i/v/o Gestational hypertension. Her previous pregnancies ended up in uneventful normal vaginal deliveries. BP – 160/96 mmHg. Her pre pregnancy weight was 115 kg and she has gained 13.5 kg in present pregnancy. The esti mated fetal weight is 3.5 kg.
• 22 hours after labour induction and 2 hours after pushing, the fetal head delivers and retracts at the perineum. Gentle traction fails to deliver the anterior shoulder.
How to diagnose shoulder dystocia
• Gentle routine traction fails to deliver the anterior shoulder with ease
• Turtle sign (retraction of neck on perineum)
• Normally next should be external rotation but head does not undergoes external rotation.
Management
• Call for help
• There are chances of asphyxia (more delay, more risk)
• DO NOT pull from below
• DO NOT push from above
• To avoid chances of brachial plexus injury
• Make the mother to lie flat on her back
• Bring the buttocks at the edge of the table
• Empty the bladder
• Consider episiotomy
• Maintain suprapubic pressure
• It helps to adduct the shoulders
• Move to next maneuver if it fails in 30 seconds
• McRobert maneuver- Hyperflexion of maternal; thigh and legs towards abdomen
• If McRobert maneuver fails..
• Delivery of posterior arm
• Rubins maneuver
• If Rubin’s maneuver fails..
• Woods corkscrew maneuver - Complete turn of baby in 180 degree, Posterior shoulder becomes anterior and vice versa
• Still unsuccessful..
• At this stage the baby might be near dead or severely asphyxiated.
• Gaskin’s All four maneuver
• Still unsuccessful..
• Extreme measure:
• Symphisiotomy
• Clavicular fracture
• Cleidotomy (cutting the clavicle with scissors)
• Zavanelli maneuver (pushing the head inside the vagina and conduct CS.)
