The recent study by Liu et al. published in Intensive Care Medicine aroused our great interest [1]. We greatly appreciate the authors’ focus on the quality of sleep in postoperative patients, which is critical to improving the quality of sleep in postoperative patients and facilitating the recovery of postoperative patients. This study has greatly improved our understanding of the effects of low-dose clonidine infusion on sleep in postoperative patients. However, we offer some suggestions for interpreting the results of this study.
