研究目的:

1.?主要目的:比较超声引导下选择性前臂神经阻滞与腋路臂丛阻滞在小儿腕部及手部手术中对术后手部运动功能的保护作用。 2.?次要目的: 评估两种阻滞方式的术中及术后镇痛效果(VAS疼痛评分、补救镇痛药物使用率)。 比较两种阻滞方式的阻滞操作时间、阻滞成功率及局麻药用量。 观察并比较两种阻滞方式相关并发症(如局部血肿、局麻药中毒、神经损伤等)的发生率。 评估患儿及监护人对两种阻滞方式的满意度。  

Objectives of Study:

Primary objective: To evaluate the onset time of anesthesia of selective forearm brachial plexus block in children undergoing upper limb surgery. Secondary objectives: 1. Primary Objective: To compare the protective effect of ultrasound-guided selective forearm nerve block versus axillary brachial plexus block on postoperative hand motor function in children undergoing wrist and hand surgery. 2. Secondary Objectives: ? To assess the intraoperative and postoperative analgesic efficacy of the two block techniques (measured by VAS pain scores and the rate of rescue analgesic use). ? To compare the procedural time, success rate, and local anesthetic dosage between the two block techniques. ? To observe and compare the incidence of complications associated with the two block techniques (such as local hematoma, local anesthetic toxicity, and nerve injury). ? To evaluate patient and guardian satisfaction with the two block techniques.

药物成份或治疗方案详述:

麻醉方法 患儿进入手术室后,立即建立静脉通路,持续监测核心生命体征:心电图(ECG)、脉搏血氧饱和度(SpO2)、心率(HR)、无创动脉血压(NIBP)及呼吸频率(RR),同步监测呼气末二氧化碳(EtCO2,维持在35–45 mmHg)。术前备好全套急救用药(如肾上腺素、阿托品)及全麻气管插管工具,确保麻醉安全。 所有患儿均在保留自主呼吸的镇静麻醉状态下接受手术: 1.?术前镇静与吸氧:鼻导管或面罩吸氧(氧流量4 L/min),静脉缓慢推注咪达唑仑0.1 mg/kg行镇静诱导;神经阻滞操作开始后,调整氧流量至5 L/min。 2.?神经阻滞操作:由同一名经过标准化培训的麻醉科医师完成超声引导下神经阻滞操作,采用针刺法评估手术区域神经阻滞效果,确认阻滞效果确切(切口区域针刺无痛)后,开始手术。 3.?术中麻醉维持:持续静脉泵注丙泊酚(负荷剂量1–2 mg/kg,维持剂量5–10 mg/kg·h),维持脑电双频指数(BIS)在40–60,保证麻醉深度适宜。 4.?术中不良事件处理: - 若术中出现疼痛反应或止血带反应(止血带部位酸胀,且HR、NIBP波动幅度超过基础值的20%),给予舒芬太尼0.1 μg/kg静脉推注对症处理,该病例不剔除,记录为“阻滞效果欠佳”,纳入意向性分析(ITT)。 - 若出现低氧血症(SpO2<90%),立即给予托下颌、密闭面罩加压给氧处理;术中根据血压波动情况,及时静脉注射心血管活性药物维持循环稳定。 5.?术中人文干预:通过语言安抚、播放轻音乐等方式,缓解患儿术中焦虑情绪。  

Description for medicine or protocol of treatment in detail:

Anesthesia Protocol Upon entering the operating room, intravenous access was established immediately, and core vital signs were continuously monitored: electrocardiography (ECG), pulse oxygen saturation (SpO?), heart rate (HR), non-invasive arterial blood pressure (NIBP), and respiratory rate (RR). End-tidal carbon dioxide (EtCO?) was simultaneously monitored and maintained at 35–45 mmHg. A complete set of emergency medications (e.g., epinephrine, atropine) and equipment for general anesthesia with tracheal intubation were prepared in advance to ensure anesthesia safety. All children underwent surgery under sedative anesthesia while maintaining spontaneous breathing: Preoperative Sedation and Oxygenation: Oxygen was administered via nasal cannula or mask (oxygen flow rate 4 L/min). Sedation was induced by slow intravenous injection of midazolam 0.1 mg/kg. After commencement of the nerve block procedure, the oxygen flow rate was adjusted to 5 L/min. Nerve Block Procedure: All ultrasound-guided nerve blocks were performed by the same anesthesiologist who had undergone standardized training. The effectiveness of the block in the surgical area was assessed using the pinprick test. Surgery began only after confirming effective blockade (absence of pain to pinprick in the incision area). Intraoperative Anesthesia Maintenance: Anesthesia was maintained with continuous intravenous infusion of propofol (loading dose 1–2 mg/kg, maintenance dose 5–10 mg/kg·h) to keep the Bispectral Index (BIS) between 40–60, ensuring an appropriate depth of anesthesia. Management of Intraoperative Adverse Events: If intraoperative pain response or tourniquet reaction occurred (soreness at the tourniquet site accompanied by fluctuations in HR or NIBP exceeding 20% of baseline), sufentanil 0.1 μg/kg was administered intravenously for symptomatic treatment. Such cases were not excluded and were recorded as "inadequate block efficacy" and included in the Intention-To-Treat (ITT) analysis. If hypoxemia occurred (SpO? < 90%), immediate intervention with jaw thrust and positive pressure ventilation via a tight-fitting mask was provided. Cardiovascular active drugs were administered intravenously as needed to maintain circulatory stability based on blood pressure fluctuations. Intraoperative Humanistic Intervention: Measures such as verbal reassurance and playing soft music were used to alleviate the child's intraoperative anxiety.

盲法:

这是一项开放性研究。由于两种神经阻滞技术的特性不同,对实施操作的麻醉医师进行设盲是不可行的。然而,评估感觉阻滞起效时间和术后肌力的结果评估者,将对分组情况设盲。

Blinding:

This is an open-label study. Due to the nature of the two different block techniques, it is not feasible to blind the anesthesiologist performing the procedure. However, the outcome assessor, who will evaluate sensory block onset time and postoperative muscle strength, will be blinded to the group assignment.
