摘要：Obje.tive. The.purpose.of this study was to e.aluate.the.association be.we.n pre.nduction modifie. Bishops score.and obste.ric outcome. including succe.sful vaginal birth afte. prior ce.are.n (VBAC) and ute.ine.rupture.in patie.ts with a pre.ious ce.are.n unde.going induction of labor. Study de.ign Me.ical re.ords of all patie.ts who had an induction of labor afte. a pre.ious ce.are.n in our institution be.we.n 1988 and 2002 we.e.re.ie.e.. Patie.ts we.e.divide. into 4 groups according to the.modifie. Bishops score.(0 to 2, 3 to 5, 6 to 8, and 9 to 12). The.rate. of succe.sful VBAC, symptomatic ute.ine.rupture. and othe. obste.ric outcome. we.e.e.aluate. in e.ch group. Multivariate.re.re.sion analyse. we.e.pe.forme. to adjust for confounding factors. Re.ults Out of 685 wome. include. in the.study, 187 (27.3%) had a modifie. Bishops score.<2, 276 (40.3%) of 3 to 5, 189 (27.6%) of 6 to 8, and 33 (4.8%) of 9 to 12. The.rate.of succe.sful VBAC significantly corre.ate. with the.modifie. Bishops score.(57.5%, 64.5%, 82.5%, and 97.0%, re.pe.tive.y, P <.001). Howe.e., the.rate.of ute.ine.rupture.was not statistically significant be.we.n the.groups (2.1%, 1.8%, 0.5%, 0.0%, P=.48). Afte. adjusting for confounding variable., a modifie. Bishops score.≥6 re.aine. associate. with succe.sful VBAC (odds ratio [OR] 2.07, 95%CI 1.28-3.35, P <..001). Conclusion The.modifie. Bishops score.be.ore.induction of labor is an inde.e.de.t factor associate. with succe.sful VBAC.
