Effect of age on postoperative 24-hour moderate-to-severe pain after radical resection of lung cancer-specific pain in the post-anaesthesia care unit: a single-centre retrospective cohort study.

For patients who underwent elective radical resection for lung cancer, age was related to postoperative 24-hour moderate-to-severe pain, and moderate-to-severe pain in the PACU had a specific effect on this relationship. Patients among the whole population and those patients without moderate-to-severe pain in the PACU were more likely to experience postoperative 24-hour moderate-to-severe pain when they were younger than 58.5 years old, and in patients with moderate-to-severe pain in the PACU, the age threshold was 62.5 years old.
