Abstract
<0.05). There were also significant differences in the Positive and Negative Affect Schedule (PANAS) scale between the two groups. The positive affect scale was higher on postoperative day 3 (POD3), while the negative affect scale was lower on POD3 and postoperative day 7 (POD7) in the esketamine group than in the control group. However, the scores of postoperative hand grip strength, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), Numeric Rating Scale (NRS) and Athens Insomnia Scale (AIS) were not significantly different between the two groups. Furthermore, mediation analysis showed that esketamine played an anti-fatigue role through improving emotional heath. Importantly, no adverse reactions occurred at this dosage of esketamine. Finally, our study suggested that subanesthetic esketamine improved postoperative fatigue, stabilized postoperative mood, reduced intraoperative remifentanil consumption, and promoted postoperative intestinal function recovery without increasing adverse reactions.
