Neonatal head ultrasounds were less common after preterm vacuum\u2010 than after preterm forceps\u2010assisted births (6.4 vs. 13.3%). Of those under 34\u2009weeks (18 vacuum and 18 forceps assisted), there were identical rates of head ultrasound in each group (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u20097, 38.9%).

No major intra\u2010 or extra\u2010cranial bleeds were found among infants who underwent a vacuum\u2010 or forceps\u2010assisted birth before 34\u2009weeks. Maternal outcomes showed significantly lower odds of obstetric anal sphincter injury (aOR 0.26) and episiotomy (aOR 0.16) with preterm vacuum compared to preterm forceps\u2010assisted births.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study adds to a small but growing body of literature that supports maternal and neonatal safety of vacuum\u2010assisted birth under 34\u2009weeks' gestation, in comparison with the use of forceps, when assisted vaginal birth is required.
