Shelley BG, et al. - In this two-year retrospective national multicentre cohort study, researchers investigated how the requirement for unplanned postoperative intensive care admission among patients undergoing lung resection surgery was influenced by the anaesthetic and analgesic techniques used. Of 11,208 participants, unplanned admission to intensive care in the postoperative period was reported in 253 patients, providing a 2.3% incidence of intensive care unit admission. Higher mortality and increased hospital length of stay were observed in patients who had an unplanned admission to intensive care unit. The chances to have an unplanned admission to intensive care were less among patients on total intravenous anaesthesia, and patients receiving epidural analgesia. In patients undergoing lung resection, the outcome was significantly influenced by both anaesthetic and analgesic technique. It is necessary to emphasize that the observed link did not directly suggest causation.
