Our aim was to identify the influence of levels of preoperative anxiety on postoperative pain in patients undergoing cardiac surgery and explore associations between preoperative anxiety, postoperative pain, analgesic requirements, and sex. We present a prospective cohort study of 116 patients undergoing cardiac surgery between January and April 2020. Preoperative anxiety was evaluated using the State-Trait Anxiety Inventory and the amount of morphine needed to keep pain intensity below 4 on the verbal numerical rating scale was recorded for 48\u00a0h post-surgery. Given the extracorporeal circulation time, type of surgery and body surface, it was observed that every percentile increase in preoperative state anxiety led to an extra 0.068\u00a0mg of morphine being administered. For each extra year of age, the amount of morphine needed decreased by 0.26\u00a0mg, no difference was observed between men and women in terms of preoperative anxiety or postoperative analgesics requirements. It may be concluded that in cardiac surgery, postoperative analgesic requirements increased with higher levels of preoperative state anxiety and decreased for every extra year of age.<\/jats:p>","DOI":"10.1038\/s41598-022-20870-9","type":"journal-article","created":{"date-parts":[[2022,10,1]],"date-time":"2022-10-01T06:02:26Z","timestamp":1664604146000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":47,"title":["The influence of preoperative anxiety on postoperative pain in patients undergoing cardiac surgery"],"prefix":"10.1038","volume":"12","author":[{"given":"Mercedes","family":"Fern\u00e1ndez-Castro","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9-Mar\u00eda","family":"Jim\u00e9nez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bel\u00e9n","family":"Mart\u00edn-Gil","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda-Fe","family":"Mu\u00f1oz-Moreno","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana-Bel\u00e9n","family":"Mart\u00edn-Santos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isa\u00edas","family":"del R\u00edo-Garc\u00eda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nat\u00e1n","family":"Redondo-P\u00e9rez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda","family":"L\u00f3pez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,10,1]]},"reference":[{"issue":"1","key":"20870_CR1","doi-asserted-by":"publisher","first-page":"89","DOI":"10.1097\/ACO.0000000000000147","volume":"28","author":"PE Bigeleisen","year":"2015","unstructured":"Bigeleisen, P.
