研究目的:

CT成像观察前锯肌阻滞后,筋膜间局麻药物的扩散范围、分布情况、吸收速率。  

Objectives of Study:

CT imaging was used to assess the diffusion range, distribution, and absorption rate of ropivacaine following serratus anterior plane block.

药物成份或治疗方案详述:

受试者开放外周静脉通道。接受前锯肌阻滞后30 min和60 min行CT成像检查;同时由具有丰富经验的影像科医师对CT图像进行分析,获取前锯肌平面内药液分布情况,计算并记录相关数据,评估液体扩散和吸收情况,计算药物吸收速率,测试受试者胸壁阻滞范围,静息和运动疼痛评分。 

Description for medicine or protocol of treatment in detail:

Peripheral intravenous access was established for the subjects. CT imaging was performed at 30 min and 60 min after serratus anterior plane block. Images were analyzed by an experienced radiologist to determine the distribution pattern of the local anesthetic within the serratus anterior plane. The diffusion characteristics and clearance dynamics of the local anesthetic were assessed, with drug absorption rates were calculated. Concurrently, dermatomal sensory blockade extent on the chest wall was evaluated, and resting/movement-evoked pain scores were recorded.  

纳入标准:

1. 年龄为18~65岁,性别不限; 2. BMI值18~24 kg/m2; 3. 拟接受局部麻醉下CT引导经皮肺结节定位并行胸腔镜手术治疗的患者; 4. 知情自愿参加,并签署知情同意书。

Inclusion criteria

1. Aged between 18 and 65 years,both sexes; 2. BMI between 18 and 24 kg/m2; 3. Patients scheduled to undergo?CT-guided percutaneous localization of pulmonary nodules, followed by video-assisted thoracoscopic surgery; 4. Agree to participate in the study voluntarily, and sign the written informed consent.

排除标准:

1. 全身感染或穿刺部位感染; 2. 已知对局部麻醉药过敏或有局麻药禁忌症的患者; 3. 严重的凝血功能障碍等血液系统疾病的患者; 4. 严重心脏(纽约心脏协会Ⅲ~Ⅳ级)、肺(1 s内用力呼气量<50%预测值)、肝、肾功能损害的患者; 5. 怀孕或哺乳期妇女; 6. 周围神经系统疾病或SAPB阻滞范围区域的神经损伤,或者不适合进行神经阻滞的患者; 7. 无法沟通或合作的患者; 8. 其他研究者判断不适合参与本研究的情况。

Exclusion criteria:

1.Patients with systemic or puncture-site infections; 2.Patients with known allergy to local anesthetics or contraindications; 3.Patients with significant coagulopathy or hematologic disorders; 4.Patients with severe organ dysfunction (Cardiac: NYHA class III-IV heart failure; Pulmonary: FEV? < 50% predicted; Hepatic: Child-Pugh grade B/C; Renal: eGFR < 30 mL/min/1.73m2); 5.Patients who are pregnant or lactating; 6.Patients with peripheral neuropathy, pre-existing neurological deficits in the SAPB target area, or anatomically unsuitable for nerve block; 7.Patients unable to communicate or cooperate with study procedures; 8.Patients with other conditions deemed inappropriate by investigators.
