AbstractRemazolam is widely used for procedural sedation in intensive care units. It has been shown to have anti-inflammatory and organ-protecting properties. However, the changes in inflammatory markers and analgesic effects of remazolam after thoracoscopic pulmonary lobectomy remain unclear. This study aims to assess the effects of the novel drug remimazolam on inflammatory factor levels and postoperative complications in thoracoscopic pulmonary lobectomy patients, providing a scientific basis for clinical use. This retrospective study analyzed 200 thoracoscopic pulmonary lobectomy patients, who were divided into a control group and a remimazolam group based on their anesthesia method. Patients in ramazolam group were anesthetized with ramazolam, while patients in control group were anesthetized with propofol. All patients were performed by the same physician team and anesthesia team. Inflammatory factors (including interleukin-6 [IL-6], C-reactive protein [CRP], including interleukin-8) were measured preoperatively and postoperatively, and postoperative complication rates were compared between the 2 groups. The levels of IL-6 and CRP were significantly higher in the remimazolam group at 7 days postoperatively compared to the control group. No significant differences were observed in preoperative inflammatory factors or postoperative including interleukin-8 levels between the 2 groups. Additionally, there were no significant differences in the overall incidence of postoperative complications or in specific complications such as pulmonary infection, atelectasis, subcutaneous emphysema, pneumothorax, surgical site infection, and arrhythmia. Patients receiving remimazolam had higher postoperative IL-6 and CRP levels compared to the control group, without an increase in postoperative complications. In clinical use, attention should be paid to the control of inflammatory indicators in patients using remazolam. However, due to potential confounding factors and the retrospective design, we cannot establish a causal relationship between remimazolam and elevated inflammatory markers. These findings suggest a possible association that requires cautious interpretation. Further research is needed to assess the clinical relevance and explore the underlying mechanisms.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
