研究目的:

本研究旨在比较 CSLA 与 OA-IP 超声引导技术在重度脊柱畸形患者颈内静脉置管中的临床应用效果,通过前瞻性随机对照试验评估两种技术的首次穿刺成功率、操作时间、并发症发生率等指标,以期为这一特殊人群的血管通路建立提供更优化的技术选择与理论依据。  

Objectives of Study:

This study aims to compare the clinical application effects of CSLA and OA-IP ultrasound-guided techniques in internal jugular vein catheterization in patients with severe spinal deformities. Through a prospective randomized controlled trial, it evaluates indicators such as first puncture success rate, operation time, and complication incidence for both techniques, with the goal of providing a more optimized technical choice and theoretical basis for vascular access establishment in this special population.

药物成份或治疗方案详述:

本研究采用前瞻性、随机、单盲、对照试验设计。纳入患者随机分配至以下两组,接受不同的超声引导颈内静脉置管技术: 试验组 (CSLA组):采用平面外联合平面内技术(Combined Short-Long Axis, CSLA) 进行超声引导下颈内静脉置管。(注:具体操作为先利用短轴平面外技术定位并引导穿刺针进入皮下,随后旋转探头切换至长轴平面内模式,实时引导穿刺针进入颈内静脉。) 对照组 (OA组):采用斜轴平面内技术(Oblique-Axis In-Plane, OA-IP) 进行超声引导下颈内静脉置管。(注:具体操作为将超声探头斜向放置,使超声束平面与血管长轴形成一定夹角,在平面内实时引导穿刺针穿刺颈内静脉。) 共同干预措施: 所有操作均由具有丰富经验的高年资麻醉医生按照标准化流程执行。每组计划纳入50例患者。 

Description for medicine or protocol of treatment in detail:

This study adopts a prospective, randomized, single-blind, controlled trial design. Enrolled patients were randomly assigned to one of the following two groups to receive different ultrasound-guided internal jugular vein cannulation techniques: Experimental Group (CSLA Group): Ultrasound-guided internal jugular vein cannulation was performed using the Combined Short-Long Axis (CSLA) technique. (Note: The specific procedure involves first using the short-axis out-of-plane technique to locate and guide the needle subcutaneously, then rotating the probe to switch to the long-axis in-plane mode to guide the needle into the internal jugular vein in real-time.) Control Group (OA Group): Ultrasound-guided internal jugular vein cannulation was performed using the Oblique-Axis In-Plane (OA-IP) technique. (Note: The specific procedure involves placing the ultrasound probe obliquely so that the ultrasound beam plane forms an angle with the long axis of the vessel, guiding the needle to puncture the internal jugular vein in-plane in real-time.) Common Intervention Measures: All procedures were performed by senior anesthesiologists with extensive experience according to a standardized protocol. Each group is planned to include 50 patients. 

纳入标准:

1.重度脊柱畸形:站立位脊柱全长 X 光片上冠状面或矢状面主弯 Cobb 角大于 90°;2.形态学上符合颈椎活动障碍;3.拟行颈内静脉穿置管;4.年龄≥12 岁且签署知情同意书。

Inclusion criteria

1. Severe spinal deformity, defined as a major coronal or sagittal curve Cobb angle greater than 90° on standing full-spine radiographs; 2. Morphological evidence of impaired cervical spine mobility; 3. Scheduled for internal jugular vein cannulation; 4. Age >= 12 years with provision of informed consent.

排除标准:

1.既往颈内静脉穿刺史;2.凝血功能异常、INR >1.5、血小板计数 <50.000;3.颈部外伤史或穿刺部位感染;4.患者拒绝;5.BMI≥30;

Exclusion criteria:

1. History of previous ipsilateral internal jugular vein cannulation; 2. Known coagulopathy (International Normalized Ratio > 1.5) or thrombocytopenia (platelet count < 50,000/μL); 3. History of trauma, surgery, or active infection at the intended puncture site; 4. Patient refusal to participate; 5. Body mass index >= 30 kg/m^2.

Calculated Results after the Study Completed public access:

公开/Public

盲法:

盲法类型:单盲 (Single-blind) 盲态实施对象: 受试者(患者)盲: 患者在全麻诱导后,不清楚医生使用的是哪种超声扫查技术。 结果评价者盲: 虽然操作医生知道分组,但负责记录并发症、术后回访的人员不参与操作,且不被告知患者的具体分组情况。 统计分析员盲: 统计学人员拿到的是代号化的数据(如 A 组、B 组),只有在统计分析完成后才进行二次揭盲。

Blinding:

This study adopted a single-blind design. Patients were blinded as the procedure followed general anesthesia induction. To minimize bias, outcome assessors and statisticians were kept blinded to the group assignments throughout the data collection and analysis phases; they were only unblinded after the completion of the statistical analysis.
