干预措施:

Interventions:

组别:

全身麻醉复合肋间神经阻滞组

样本量:

60

Group:

General anesthesia combined with intercostal nerve block group

Sample size:

干预措施:

患者全身麻醉后15分钟,由同一名具备超声引导区域阻滞丰富经验的麻醉医生开始施行超声引导下肋间神经阻滞。以超声 “双标志识别法”(肋骨下缘+胸膜线)定位切口对应肋间+相邻1个肋间(共2-3个肋间),彩色多普勒排除血管,平面内进针,角度≤25°,避免穿透胸膜;回抽无血无气,缓慢注射布比卡因脂质体(133mg/20 mL)。

干预措施代码:

Intervention:

Fifteen minutes after the patient had undergone general anesthesia, the same anesthesiologist with extensive experience in ultrasound-guided regional anesthesia began performing an ultrasound-guided intercostal nerve block. Using ultrasound "dual marker identification" (rib inferior margin + pleural line) to locate the incision corresponding to the intercostal space and one adjacent rib space (a total of 2-3 rib spaces), color Doppler was used to rule out blood vessels. The needle was inserted within a plane, with an angle <=25°, to avoid penetrating the pleura. No blood or air was aspirated, and bupivacaine liposome (133 mg/20 mL) was slowly injected.

Intervention code:

组别:

全身麻醉复合局部浸润组

样本量:

60

Group:

Group with general anesthesia combined with local infiltration.

Sample size:

干预措施:

患者手术结束后、皮肤缝合前,由参与手术的手术医生进行布比卡因脂质体局部浸润(133mg/20 mL)。由皮下层往肌层分层浸润:针尖刺入切口下方肌层(胸腔镜手术主要为胸大肌、肋间肌),回抽无血后,分3-4个点注射药物。随后沿切口两侧皮下组织缓慢推进,边退针边注射药物,形成 “皮下药物带”,确保覆盖真皮层与皮下脂肪层。

干预措施代码:

Intervention:

After the patient’s surgery and before skin suturing, the operating surgeon administers local infiltration of bupivacaine liposomes (133 mg/20 mL). The infiltration is layered from the subcutaneous layer to the muscular layer: the needle tip is inserted into the muscular layer beneath the incision (in thoracoscopic surgery, primarily the pectoralis major and intercostal muscles). After suctioning out any blood, the medication is injected into 3-4 points. Subsequently, the infiltration is slowly advanced along both sides of the incision through the subcutaneous tissue, with the needle being retracted and the medication being injected simultaneously, forming a "subcutaneous drug band" to ensure coverage of the dermal layer and subcutaneous fat layer.
