Current data do not differentiate clearly between preterm delivery and\n          low birthweight. We aimed to evaluate the impact of non-metal vacuum cup extraction on neonatal head injuries related to birth trauma in newborns with low birthweights (&lt;\u00a02500\u00a0g).<\/jats:p><jats:p>\n          Materials and Methods A retrospective cohort of 3377 singleton pregnancies delivered by vacuum extraction from 2014 to 2019. All were gestational age \u2265\u00a034\u00a0w. We compared 206 (6.1%)\n          neonates with low birthweights &lt;\u00a02500\u00a0g to 3171 (93.9%) neonates with higher birthweights, divided into 3 subgroups (2500\u20132999\u00a0g, 3000\u20133499\u00a0g, and \u2265\u00a03500\u00a0g). A primary composite outcome\n          of neonatal head injuries related to birth trauma was defined.<\/jats:p><jats:p>\n          Results The lowest rates of subgaleal hematoma occurred in neonates &lt;\u00a02500\u00a0g (0.5%); the rate increased with every additional 500\u00a0g of neonatal birthweight (3.5%, 4.4% and 8.0% in\n          the 2500\u20132999\u00a0g, 3000\u20133499\u00a0g, and \u2265\u00a03500\u00a0g groups, respectively; p\u00a0=\u00a00.001). Fewer cephalohematomas occurred in low birthweight neonates (0.5% in &lt;\u00a02500\u00a0g), although the percentage\n          increased with every additional 500\u00a0g of birthweight (2.6%, 3.3% and 3.7% in the 2500\u20132999\u00a0g, 3000\u20133499\u00a0g, and \u2265\u00a03500\u00a0g groups, respectively, p\u00a0=\u00a00.020). Logistic regression found increasing\n          birthweight to be a significant risk factor for head injuries during vacuum extraction, with adjusted odds ratios of 8.12, 10.88, and 13.5 for 2500\u20132999\u00a0g, 3000\u20133499\u00a0g, and \u2265\u00a03500\u00a0g,\n          respectively (p\u00a0=\u00a00.016). NICU hospitalization rates were highest for neonates weighing &lt;\u00a02500\u00a0g (10.2%) compared to the other groups (3.1%, 1.7% and 3.3% in 2500\u20132999\u00a0g, 3000\u20133499\u00a0g,\n          \u2265\u00a03500 respectively, p\u00a0&lt;\u00a00.001).<\/jats:p><jats:p>\n          Conclusions Vacuum extraction of neonates weighing &lt;\u00a02500\u00a0g at 34\u00a0w and beyond seems to be a safe mode of delivery when indicated, with lower rates of head injury related to birth\n          trauma, compared to neonates with higher birthweights.<\/jats:p>","DOI":"10.1055\/a-1987-5765","type":"journal-article","created":{"date-parts":[[2023,1,19]],"date-time":"2023-01-19T23:35:25Z","timestamp":1674171325000},"page":"201-211","source":"Crossref","is-referenced-by-count":3,"title":["Head
