Слайды и текст этой презентации
Слайд 4Pathophysiology
Face presentation is an extended attitude
Results in largest head
diameter: Occipitomental
Слайд 7Cont.
Anencephaly
Loops of cord around the neck
Tumours in front of neck,
cystic hygroma, goitre
Слайд 8Diagnosis
During pregnancy
High head
Head protuberance on the same side
as the back
USG
In labour
Mouth, jaws, nose,alveolar and orbital ridges
are felt
Слайд 10Labour in face presentation
Prolonged labour
Early ROM
Perineal & vaginal tears
May end
in obstructed labour due to mentoposterior or mentotransverse position
Слайд 11Management
Do not attempt to convert face presentation to vertex
Never apply vacuum extractor to face
Do not apply internal
scalp electrodes Avoid Oxytocin in most cases
Consider large episiotomy if fetus delivers vaginally
Слайд 12Management
No active intervention
Wait for the spontaneous rotation and delivery
Epidural analgesia
If
prolonged second stage and mento- anterior :apply forceps
Слайд 13Cont.
If persistant mentotransverse:
rotation manually or with Kielland forceps
In
persistant mentoposterior: C.Section
Слайд 15Epidemiology
Incidence: 0.02% of singleton deliveries
Brow is an area between
the orbital ridges and anterior fontanelle
Results when head is halfway
between flexion & extension
Слайд 18Diagnosis
Never made during pregnancy
In labour
High head
Frontal suture & anterior fontanelle
on one side and orbital ridges on other side
Слайд 20Management
Cesarean section required in most cases
Brow presentation rarely can
deliver vaginally unless:
spontaneously converts to vertex or face presentation
fetus is very small or pelvis is very large
Слайд 21Cont.
Do not attempt to convert brow presentation to vertex
Never
apply vacuum extractor to brow presentation
Do not apply internal
scalp electrodes Avoid Oxytocin
