Traction force profile in children with severe perinatal outcomes delivered with a digital vacuum extraction handle: A case–control study

“…Is it possible, with current knowledge, to design a safety limit for total traction force during VAD? Pettersson et al 27 studied a cohort of 331 VADs delivered with the VIH3. The prevalence of severe perinatal outcomes was 1.8% and admittance to the NICU was 7.2%.…”

“…The VIH3 was implemented as part of two prospective clinical studies 27 , 29 and used by obstetricians (Supporting Information Figure S1 ). It is hooked to a Bird metal cup (only the 50 mm cup was used) applied to the fetal scalp with 80 kPa negative pressure and contains a force sensor that is connected via Bluetooth® to a tablet computer.…”

“…The VIH3 was implemented as part of two prospective clinical studies 27,29 and used by obstetricians (Supporting Information Figure S1). It Conclusions: Children with severe perinatal outcomes had traction force profiles with significantly higher forces.…”

“…The previous suggested peak force limits of 216–220 Newtons for cup detachment, 23 , 24 , 25 as well as the force used by the operator during traction, are often underestimated. 26 According to Pettersson et al, 27 a high level of total traction force is associated with an increased risk of admission to the neonatal intensive care unit (NICU).…”
