研究目的: |
1. 探索右美托咪定对脓毒症结直肠癌术后外周血淋巴细胞亚群比例及炎性因子水平的影响; 2. 评价右美托咪定对围术期血流动力学稳定性及镇静/镇痛暴露的影响; 3. 评估围术期右美托咪定使用对早期临床结局的影响; 4. 评价脓毒症患者围术期右美托咪定使用的安全性; 5. 探索免疫/炎症指标变化与临床结局之间的相关性及潜在中介效应; 6. 通过进行预设亚组(SOFA分层、术式〔开腹/腔镜〕、术后去向〔ICU/病房〕)的疗效异质性分析,为优化围术期镇静策略提供依据。 |

Objectives of Study: |
1. To explore the effects of dexmedetomidine on the proportions of peripheral blood lymphocyte subsets and levels of inflammatory cytokines in postoperative colorectal cancer patients with sepsis. 2. To evaluate the effects of dexmedetomidine on perioperative hemodynamic stability and exposure to sedative/analgesic agents. 3. To assess the impact of perioperative dexmedetomidine administration on early clinical outcomes. 4. To evaluate the safety of perioperative dexmedetomidine use in patients with sepsis. 5. To explore the correlations between changes in immune/inflammatory indicators and clinical outcomes, as well as potential mediating effects. 6. To conduct predefined subgroup analyses, including SOFA score stratification, surgical approach [open surgery/laparoscopic surgery], and postoperative destination [ICU/general ward], to investigate treatment-effect heterogeneity and provide evidence for optimizing perioperative sedation strategies. |

随机方法(请说明由何人用什么方法产生随机序列): |
由不参与受试者筛选、入组、给药实施及结局评价的独立研究人员或统计人员,采用计算机随机数字表法生成随机分组序列。符合入组标准的受试者按照1:1比例随机分配至右美托咪定组或安慰剂对照组,每组30例。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
An independent researcher or statistician who is not involved in participant screening, enrollment, intervention administration, or outcome assessment will generate the random allocation sequence using a computer-generated random number table. Eligible participants will be randomly assigned in a 1:1 ratio to the dexmedetomidine group or the placebo control group, with 30 participants in each group. |
