研究目的:

探究采用DPE技术进行分娩镇痛时,60 min 间隔程序化硬膜外间歇推注(PIEB)模式下,0.1% 罗哌卡因联合 0.3 μg/mL 右美托咪定的最佳推注剂量,实现产妇有效镇痛,同时保障母婴安全,降低不良反应发生率。  

Objectives of Study:

To investigate the optimal bolus dose of 0.1% ropivacaine combined with 0.3 μg/mL dexmedetomidine in the mode of programmed epidural intermittent bolus (PIEB) at 60-minute intervals for labor analgesia via the DPE technique, so as to achieve effective analgesia for puerperae, ensure maternal and infant safety, and reduce the incidence of adverse reactions.

干预措施:

序贯规则:以偏币序贯法探索有效剂量(采用偏币序贯法,按照8、9、10、11、12、13mL剂量进行调整。每位产妇从 8 mL 剂量开始,后续产妇根据前 1 例产妇镇痛结局调整剂量:有效者(无 PCEA 追加 / 医师推注)下 1 例 1/9 概率下调 1 mL、8/9 概率维持原剂量;无效者(需 PCEA 追加 / 医师推注)下 1 例上调 1 mL。)。初始剂量为 10 mL 0.1% 罗哌卡因复合 0.3 μg/mL 右美托咪定;注射间隔 60 min;首名产妇的单次给药剂量设定为 8 mL。

干预措施代码:

Intervention:

The biased coin design (BCD) was adopted to explore the effective dose, with dose adjustments performed at 8, 9, 10, 11, 12 and 13 mL. Each parturient started with a dose of 8 mL, and the dose for subsequent parturients was adjusted according to the analgesic outcome of the previous one: for a responsive case (no PCEA bolus or clinician-administered bolus required), the dose for the next parturient was decreased by 1 mL with a probability of 1/9 or maintained with a probability of 8/9; for a non-responsive case (PCEA bolus or clinician-administered bolus required), the dose for the next parturient was increased by 1 mL. The initial dose was defined as 10 mL of 0.1% ropivacaine combined with 0.3 μg/mL dexmedetomidine, with an injection interval of 60 minutes; the single administration dose for the first parturient was set at 8 mL.

指标类型:

主要指标

Outcome:

Effective analgesic

Type:

Primary indicator

测量时间点:

镇痛开始后 6 小时内或宫颈完全扩张前(以先发生者为准),无需 PCEA 追加剂量或医师额外推注药物,NRS 评分持续≤3 分。若患者需要追加剂量,需进行阴道检查评估宫颈扩张程度,以确认产妇处于第一产程或第二产程。

测量方法:

Measure time point of outcome:

Within 6 hours after the initiation of analgesia or before complete cervical dilation (whichever occurs first), no additional PCEA bolus or supplementary clinician-administered drug bolus was required, and the NRS score remained ≤ 3 points. If additional dosing was needed for the patient, a vaginal examination was performed to assess the degree of cervical dilation, so as to confirm that the parturient was in the first or second stage of labor.
