If you are unable to define position......
- Ask a more senior colleague to help define position
- Is there excessive caput/moulding? (& ?CPD)
- Will an ultrasound scan help? (look for fetal spine/eyes)
Do not apply a ventouse when unable to define position with the hope that the head will descend with traction...
You are at risk of failing and causing significant fetal trauma.
Head above the spines
Excessive caput and moulding
Instrumental delivery should not be attempted
