In women with pre\u2010eclampsia, preload infusion increased both SI and HR, causing a significant rise in CI, while in healthy parturients, only HR rose. In both the groups, spinal blockade reduced SVRI but CI remained stable. At the moment of delivery, CI increased in both groups. In uncomplicated pregnancies, both SI and HR increased, but in women with pre\u2010eclampsia, SI was not altered and the rise in CI was due to an increase in HR only. After the reversal of anaesthesia, haemodynamics in the control group returned to baseline values, whereas in women with pre\u2010eclampsia, SI and CI fell to levels that were significantly lower than the levels observed before surgery.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions\u2002<\/jats:bold>\n                    In women with pre\u2010eclampsia, inability to increase SI at the moment of delivery may suggest dysfunction of the left ventricle to adapt to volume load caused by delivery and prompts concern for the increased risk of pulmonary oedema.\n                  <\/jats:p>","DOI":"10.1111\/j.1471-0528.2006.00931.x","type":"journal-article","created":{"date-parts":[[2006,4,28]],"date-time":"2006-04-28T12:06:38Z","timestamp":1146225998000},"page":"657-663","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Maternal haemodynamics in pre\u2010eclampsia compared with normal pregnancy during caesarean delivery"],"prefix":"10.1111","volume":"113","author":[{"given":"K","family":"Tihtonen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T","family":"K\u00f6\u00f6bi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Yli\u2010Hankala","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H","family":"Huhtala","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J","family":"Uotila","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,4,28]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1067\/mob.2001.117314"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/sj.jp.7200315"},{"key":"e_1_2_6_4_2","first-page":"113","article-title":"Maternal deaths associated with cesarean section","volume":"45","author":"Roopnarinesingh S","year":"1996","journal-title":"West Indian Med J"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-199905000-00009"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/0029-7844(95)00139-I"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1213\/01.ANE.0000073610.23885.F2"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(84)90357-0"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.HYP.17.6.1072"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1399-6576.1985.tb02178.x"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(89)90184-1"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(70)90554-5"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(15)33636-X"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.0001-6349.2005.00489.x"},{"key":"e_1_2_6_15_2","doi-asserted-by":"crossref","first-page":"263","DOI":"10.1016\/0002-9378(80)90246-X","article-title":"Hemodynamics in patients with severe toxemia during labor and delivery","volume":"138","author":"Raferty T","year":"1980","journal-title":"Am J Obstet Gynecol"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2044.1980.tb03886.x"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(89)90901-0"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.3109\/00016349609033302"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003246-199705000-00012"},{"key":"e_1_2_6_20_2","doi-asserted-by":"publisher","DOI":"10.1097\/00001503-199902000-00003"},{"key":"e_1_2_6_21_2","doi-asserted-by":"publisher","DOI":"10.1097\/00006250-199912000-00014"},{"key":"e_1_2_6_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(00)24854-0"},{"key":"e_1_2_6_23_2","doi-asserted-by":"publisher","DOI":"10.1093\/bja\/76.5.616"},{"key":"e_1_2_6_24_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1399-6576.1996.tb05551.x"},{"key":"e_1_2_6_25_2","first-page":"902","article-title":"Atrial natriuretic peptide concentrations and hemodynamic effects of acute plasma volume expansion in normal pregnancy and preeclampsia","volume":"79","author":"Nisell H","year":"1992","journal-title":"Obstet Gynecol"},{"key":"e_1_2_6_26_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-8703(91)90024-C"},{"key":"e_1_2_6_27_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.1996.tb09548.x"}],"container-title":["BJOG: An International Journal of Obstetrics &amp;
