Most previous studies of core temperature in caesarean delivery patients have not been conducted with accurate measurements for the complete perioperative period. Therefore, we conducted a prospective observational study to identify the incidence and duration of pre\u2010 and post\u2010operative maternal hypothermia with a high accuracy continuous temperature monitoring system.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Women \u226518\u2009years old presenting for elective caesarean delivery under spinal anaesthesia were invited to participate in the study. The primary outcomes were the incidence and duration of perioperative maternal hypothermia (&lt;36.0\u00b0C). Maternal core temperatures were measured with the non\u2010invasive zero\u2010heat\u2010flux thermometer (Bair Hugger Temperature Monitoring System, 3M) throughout the perioperative course.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 40 participants were recruited to the study. The incidence of perioperative hypothermia was 32.5%, with a duration of 77\u2009\u00b1\u200940\u2009min (mean\u2009\u00b1\u2009standard deviation). The hypothermic patients had similar core temperature as the normothermic patients at baseline preoperatively, but significantly lower temperature at operating room arrival and during the remaining study period. Forty percent of all patients reported thermal discomfort and felt cold on admission to post anaesthesia care unit, whereas 33% had shivering. Neither thermal discomfort nor shivering were associated with hypothermia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In the present study almost a third of the women undergoing elective caesarean delivery developed perioperative hypothermia with a core temperature &lt;36.0\u00b0C. The mean duration of maternal hypothermia was 77\u2009min, lasting well into the postoperative period for many patients. These data should remind healthcare professionals of the importance of measuring core temperature in all phases of the perioperative setting and to consider optimal warming measures to avoid and treat hypothermia.<\/jats:p><\/jats:sec>","DOI":"10.1111\/aas.14340","type":"journal-article","created":{"date-parts":[[2023,10,25]],"date-time":"2023-10-25T04:55:30Z","timestamp":1698209730000},"page":"247-253","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Maternal hypothermia during elective caesarean delivery: A prospective observational study"],"prefix":"10.1111","volume":"68","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-0097-1804","authenticated-orcid":false,"given":"Irene","family":"Brodshaug","sequence":"first","affiliation":[{"name":"Department of Nurse Anaesthesia, Division of Emergencies and Critical Care Oslo University Hospital  Oslo Norway"},{"name":"Institute of Clinical Medicine, Faculty of Medicine University of Oslo  Oslo Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth","family":"Reine","sequence":"additional","affiliation":[{"name":"Department of Nurse Anaesthesia, Division of Emergencies and Critical Care Oslo University Hospital  Oslo Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2487-0839","authenticated-orcid":false,"given":"Johan","family":"Raeder","sequence":"additional","affiliation":[{"name":"Institute of Clinical Medicine, Faculty of Medicine University of Oslo  Oslo Norway"},{"name":"Department of Anaesthesiology, Division of Emergencies and Critical Care Oslo University Hospital  Oslo Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,10,24]]},"reference":[{"key":"e_1_2_11_2_1","volume-title":"Hypothermia: Prevention and Management in Adults Having Surgery","author":"National Institute for Health and Care Excellence: Guidelines","year":"2016"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(15)00981-2"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-444-64074-1.00041-0"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/aorn.13327"},{"key":"e_1_2_11_6_1","unstructured":"SesslerD.Perioperative temperature management.
