Instrumental delivery
Published in Sheila Broderick, Ruth Cochrane, Trauma and Birth, 2020

Vacuum extraction means a device (e.g. a Ventouse) is used to aid delivery of the baby’s head by the application of a suction cup to the scalp. Because the suction cup is placed on the head rather than around it, the Ventouse does not add to the size of the head that is coming through the maternal pelvis and so in theory the risk of damage to the mother should be the same as with a normal delivery. Vacuum extraction is not used for babies before 36 weeks gestation.

The potential complications of a ventouse delivery can be divided into maternal and fetal complications: Maternal complications include vaginal wall laceration from entrapment of the vaginal mucosa between the suction cup and fetal head, and risk of cervical damage.Fetal complications include cephalhaematoma, subgaleal haematoma, intracranial haemorrhage and scalp lacerations.

Ventouse – less maternal trauma.Ventouse – more cephalhaematorna, retinal haemorrhage and maternal worries regarding the baby.

Vaginal delivery in PAH patients should ideally be performed with epidural anesthesia, as this has a limited impact on hemodynamics and reduces pain during labor. Single-shot spinal anesthesia and nitrous oxide should be avoided due to the associated risk of hypotension and increased PVR, respectively [78,79]. Forceps or ventouse devices can assist in delivery and reduce maternal straining during labor [7,80]. If induction of labor is required, caution should be exercised when using oxytocin. A low dose is preferable, as mortality and other adverse outcomes, including intractable arrhythmia and pulmonary hypertensive crisis, have been reported [4,58,65]. Both vaginal and cesarean sections carry their own risks, neither modality offers a perfect solution and decision-making around the mode and timing of delivery should be individualized.
The BD Odon Device™: an update of its current state

In 2017, O’Brien published the first three studies about the application of BD Odon Device™ in mannequins. One of them aimed to evaluate the interaction between health providers and the device. This study demonstrated that some modifications to the first model of the device as well as providing specific training to practitioners prior to its use—instruction for use, training video and one-to-one training—improved the percentage of correct use from 25 to 100% in all three main steps—preparation of the device, application and completing delivery (O’Brien et al. 2017a). Another study evaluated the sitting position of the device, its movement during delivery and the degree of perineal distension. The device was reliably sited in average over the foetal head position and the degree of perineal distension was similar to vacuum extraction of forceps delivery (O’Brien et al. 2017b). The third study evaluated the pressure and traction forces exerted by the BD Odon Device™ compared to forceps or Kiwi® vacuum extractor during simulated births. The perineal distention generated by the BD Odon Device™ was greater than ventouse but less than forceps (O’Brien et al. 2017c).

Figure 4 illustrates that regional and national assisted delivery data rates are very similar. Around 30% of vaginal deliveries were assisted by episiotomy (most common), forceps or ventouse at Raigmore Hospital. There was no national data breakdown for episiotomy alone. With any vaginal delivery, trauma to the vulva, vagina and cervix could be sustained. Studies have shown (Gurol-Urganci et al. 2013; Thiagamoorthy et al. 2014) that with assisted delivery there is also an increased risk of obstetric anal sphincter injury (OASI) so we examined our OASI rates at Raigmore hospital. This figure shows that Raigmore Hospital had a 2.6% incidence of third-degree tear at SVD and 4.4% incidence of third-degree tear at assisted delivery. These figures are in keeping with the lower rates of documented UK incidence (Gurol-Urganci et al. 2013; Thiagamoorthy et al. 2014).
