Objectives of Study: |
The primary objective of our study is to compare the incidence of post-induction hypotension between either ciprofol or remimazolam and propofol in elderly patients undergoing general anesthesia induction. Additionally, we conducted an exploratory analysis to compare the incidence of post-induction hypotension between ciprofol and remimazolam, two novel intravenous anesthetics, in this elderly population. |

盲法: |
(1)由于三种药物在使用剂量以及性状方面有差异,负责诱导给药的麻醉医师1知道研究组分配。 (2)负责患者招募的研究者不参与患者的麻醉和围手术期管理。 (3)两名麻醉医师参与麻醉诱导,其中医师1知道分组情况对患者进行诱导给药。为保证盲法的实施,医师1提前计算好患者需要使用的负荷剂量和可能需要的补救剂量,统一使用50 ml注射器抽取研究药物(2%丙泊酚/2.5%环泊酚/2%瑞马唑仑),并在延长管外面用不透光的锡纸进行包裹。所有研究药物均使用思路高注射泵泵注保证匀速推注药物,根据提前计算好的用量设定泵速。医师1在诱导给药开始前需在患者留置针处铺上中等大小的手术单,遮挡住可能暴露分组情况的部分输液管。同时,医师1负责手术的麻醉管理并对术中数据(麻醉药物使用量和持续时间,手术类型和持续时间,液体输注、估计失血量和尿量)进行记录。 另一名麻醉医师2不知道分组情况。在医师1开始静注研究药物时,告知医师2,医师2开始计时并判断患者意识消失情况,如3分钟后患者意识仍未消失,告知医师1进行补救。期间血管活性药的使用时机与剂量由医师2负责,医师1协助进行静脉推注。麻醉医师2同时负责患者的面罩通气以及气管插管。 除两名麻醉医师外,一名麻醉护士记录数据(除研究药物用量以外主要指标,次要指标以及附加指标),其中意识消失时间和血管活性药使用量由麻醉医师2告知麻醉护士,血流动力学数据以及BIS值通过实时监测监护仪对数据进行记录。 (3)负责基线指标收集和随访(安全评估指标)的为同一名研究者,其不参与麻醉和围手术期管理,也不了解研究组分配。他们在研究前接受了培训,以遵循研究方案、进行结果评估和收集随访数据。他们不得与进行麻醉诱导的麻醉医师就分组情况进行交流。 (4)在整个研究期间,患者、外科医生也不知道患者的分组情况。 (5)统计分析将由一名独立的研究人员进行。 |

Blinding: |
(1) Due to differences in dosage and formulation among the three study drugs, Anesthesiologist 1, responsible for drug induction, was aware of the group assignment. (2) The investigator responsible for patient recruitment did not participate in patient anesthesia or perioperative management. (3) Two anesthesiologists participated in anesthesia induction. Anesthesiologist 1, knowing the group assignment, performed the induction drug administration. To ensure blinding, Anesthesiologist 1 pre-calculated the patient's required loading dose and any potential rescue doses. The study drug (2% Propofol / 2.5% Ciprofol / 2% Remimazolam) was uniformly withdrawn into 50 ml syringes. The extension tubing was wrapped in opaque aluminum foil. All study drugs were administered using a SiLuGao infusion pump to ensure constant-rate infusion, with the pump speed set according to the pre-calculated dose. Before starting drug infusion, Anesthesiologist 1 draped the patient's intravenous access site with a medium-sized surgical drape to conceal any potentially unblinding parts of the infusion line. Anesthesiologist 1 was also responsible for intraoperative anesthetic management and recorded intraoperative data (anesthetic drug usage and duration, surgery type and duration, fluid administration, estimated blood loss, and urine output). Anesthesiologist 2 remained blinded to the group assignment. When Anesthesiologist 1 began intravenous infusion of the study drug, Anesthesiologist 2 was notified and started timing to assess loss of consciousness (LOC). If LOC was not achieved within 3 minutes, Anesthesiologist 2 instructed Anesthesiologist 1 to administer rescue medication. During this period, the timing and dosage of vasoactive drugs were managed by Anesthesiologist 2, with Anesthesiologist 1 assisting in intravenous bolus administration. Anesthesiologist 2 was also responsible for mask ventilation and tracheal intubation. In addition to the two anesthesiologists, an anesthesia nurse recorded data (primary outcomes excluding study drug dosage, secondary outcomes, and additional outcomes). The time to LOC and the amount of vasoactive drugs used were reported to the anesthesia nurse by Anesthesiologist 2. Hemodynamic data and BIS values were recorded in real-time by directly monitoring the patient monitor. (3) Baseline data collection and follow-up (safety assessment) were performed by the same investigator, who did not participate in anesthesia or perioperative management and remained blinded to group assignment. This investigator received training prior to the study to adhere to the protocol, perform outcome assessments, and collect follow-up data. They were prohibited from communicating with the inducing anesthesiologist about group assignment. (4) Throughout the study period, both the patient and the surgeon remained blinded to the patient's group assignment. (5) Statistical analysis was performed by an independent researcher. |
