Device application with a contraction
The original IFU stated that the Odon Device should be applied between
contractions, as is standard practice with other devices for AVB
(forceps and ventouse). It became apparent during the first two
attempted AVBs that this disimpacted the fetal head out of the pelvis
and operators were unable to correctly place the device:
D1: ‘Again, I had to use significant pressure to try and get the
device over the fetal head. And loads of liquor came down during the
application suggesting that there was some degree of disimpaction.’
By the third attempted birth, operators had adapted their technique to
include fundal pressure to aid application, which resulted in successful
device application and the first successful AVB. The use of fundal
pressure, although successful, was not well tolerated by women without a
regional anaesthetic:
M3: ‘Significant fundal pressure that was used at the
time…she was uncomfortable…maybe that will be something up
for review.’
Following feedback from qualitative findings, the application technique
was adapted again during the eighth birth. This was the first time the
Odon Device was applied during a contraction without the use of fundal
pressure, resulting in a successful application and birth:
D2: ‘I haven’t used fundal pressure since delivery number two or
three for me, but what has been very successful is putting it on during
a contraction. I think.’
