Third or fourth degree perineal tears and vaginal and cervical lacerations were all observed less frequently among women delivered with the vacuum extractor. The need for post\u2010partum bladder catheterization was also reduced for these women. Babies born by the means of the vacuum extractor ran an increased risk of cephalhematoma and neonatal jaundice. No difference in major neonatal morbidity was observed between the two groups. The Kobayashi instrument appears to be a useful alternative to forceps in low vaginal instrumental deliveries.<\/jats:p>","DOI":"10.3109\/00016348709022072","type":"journal-article","created":{"date-parts":[[2007,11,13]],"date-time":"2007-11-13T19:05:28Z","timestamp":1194980728000},"page":"643-647","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Maternal and neonatal morbidity in instrumental deliveries with the kobayashi vacuum extractor and low forceps"],"prefix":"10.1111","volume":"66","author":[{"given":"Laurence","family":"Meyer","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacques","family":"Mailloux","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sylvie","family":"Marcoux","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pierre","family":"Blanchet","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francois","family":"Meyer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,1,11]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00006254-197510000-00001"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.1.5392.1216"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003081-198203000-00022"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.292.6513.75"},{"key":"e_1_2_1_6_1","first-page":"212","article-title":"Fetal injury due to the vacuum extractor","volume":"19","author":"Agiiero O.","year":"1962","journal-title":"Obstet Gynecol"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.3.5673.743"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1515\/jpme.1982.10.6.273"},{"key":"e_1_2_1_9_1","volume-title":"Epidemiologic research","author":"Kleinbaum D G.","year":"1982"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.1983.tb06455.x"},{"key":"e_1_2_1_11_1","first-page":"571","article-title":"Comparison of maternal and fetal effects of vacuum extraction with forceps or cesarean deliveries","volume":"57","author":"Greis J B.","year":"1981","journal-title":"Obstet Gynecol"},{"key":"e_1_2_1_12_1","first-page":"624","article-title":"Soft cup vacuum extraction: a comparison of outlet delivery","volume":"66","author":"Dell D L.","year":"1985","journal-title":"Obstet Gynecol"},{"key":"e_1_2_1_13_1","first-page":"503","article-title":"Cohort study of silastic obstetric vacuum cup deliveries.
