Objective: Perioperative multimodal analgesia is an important step in enhanced recovery after surgery (ERAS) care. Many factors, such as preoperative chronic pain and anxiety, may provide information about the expected postoperative pain. In this study, we evaluated preoperative pain and anxiety and investigate their effects on acute postoperative pain in patients undergoing elective cardiac surgery. Methods: After ethics committee approval, 67 consenting patients undergoing on-pump cardiac surgery under the ERAS program were included in our prospective observational study. Pre- and postoperative pain scores were obtained using a numeric rating scale (NRS) at rest and during movement. Preoperative anxiety was assessed on a 0-10 scale, and data were recorded. The relationships between pre-operative pain/anxiety and postoperative pain were evaluated using correlation analysis. Results: In preoperative pain assessment, the percentage of patients with a pain score above 4 with NRS was 1.5%, regardless of whether they were at rest or mobilize. In postoperative pain assessment, there were 20.9% and 34.3% patients with NRS >4 at rest and mobilization, respectively. 7.5% of patients had preoperative anxiety of grade 5 or higher. While preoperative pain was not correlated with postoperative pain, preoperative anxiety had a moderate positive correlation with postoperative pain (r=0.382, P=0.003). Conclusion: The prevalence of preoperative pain in patients who underwent cardiac surgery is quite low and is not associated with postoperative pain. There is also a significant relationship between the severity of preoperative anxiety and postoperative pain. [ABSTRACT FROM AUTHOR]
