研究目的: |
本研究拟开展一项随机双盲阳性对照试验,以拟接受痔疮切除术的患者为研究对象,采用全身麻醉联合术毕肛周局部浸润(GAL)的麻醉技术,评估布比卡因脂质体(LB)与普通布比卡因混合液肛周局部浸润相较于单纯普通布比卡因浸润在痔切除术后疼痛控制中的有效性及安全性,旨在为临床实践提供最佳指导依据。 |

Objectives of Study: |
This study intends to conduct a randomized double-blind positive-controlled trial, targeting patients scheduled for hemorrhoidectomy. It will use general anesthesia combined with postoperative perianal local infiltration (GAL) anesthesia technique to evaluate the efficacy and safety of liposomal bupivacaine (LB) compared with a mixture of regular bupivacaine for perianal local infiltration, against simple regular bupivacaine infiltration, in controlling postoperative pain after hemorrhoidectomy. The aim is to provide optimal guidance for clinical practice. |

纳入标准: |
1.年龄>=18 岁,BMI 18.0~30.0 kg/m^2,男性体重>50 kg 且非孕妇/哺乳期女性体重>45 kg; 2.诊断为混合痔,拟在全身麻醉下行痔疮切除手术,且预计切口总长度≥3cm 的患者。单痔核切口多为放射状梭形,长度约1~2 cm;总切口长度通常为1.5~5 cm(多数2~4 cm)。总切口>=3 cm 提示需处理至少2个及以上较大痔核,手术创面较大,术后疼痛刺激强度达中度及以上(术后24~48 小时尤为剧烈)。选择此类患者可确保疼痛刺激强度足够,以准确评估布比卡因脂质体与盐酸布比卡因混合液的镇痛效果,该标准参考自文献; 3. ASA 分级Ⅰ~Ⅲ级。 |

|
Inclusion criteria |
1. Age >= 18 years, BMI 18.0~30.0 kg/m^2, male weight > 50 kg, and non-pregnant/non-breastfeeding female weight > 45 kg; 2. Diagnosed with mixed hemorrhoids and scheduled for hemorrhoidectomy under general anesthesia, with an expected total incision length >= 3 cm. Single hemorrhoid incisions are mostly radial fusiform, approximately 1~2 cm in length; the total incision length is generally 1.5~5 cm (mostly 2~4 cm). A total incision length >= 3 cm indicates the need to treat at least two or more large hemorrhoids, resulting in a relatively large surgical wound and postoperative pain intensity reaching moderate or above (especially severe within 24~48 hours postoperatively). Selecting such patients ensures sufficient pain stimulus intensity to accurately evaluate the analgesic effect of liposomal bupivacaine versus bupivacaine hydrochloride mixture, as referenced in the literature; 3. ASA classification I~III. |

排除标准: |
1.随机化前6个月内有心肌梗死、不稳定型心绞痛病史或严重心律失常病史者; 2.随机化前1年内有药物滥用或酒精滥用史者(酒精滥用定义:平均每日饮酒>2单位,1单位=360mL啤酒/45mL 40%vol白酒/150mL葡萄酒),或试验药物给药前24小时内摄入含酒精食物/饮料者; 3.患有精神系统疾病(如精神分裂症、抑郁症等)或认知功能障碍者; 4.存在其他可能干扰术后疼痛评估的躯体疼痛者; 5.对布比卡因、其他酰胺类局麻药或试验期间拟用药物过敏或存在禁忌症者. |
||||||||||||||||||||||
|
Exclusion criteria: |
1. Individuals with a history of myocardial infarction, unstable angina, or serious arrhythmias within 6 months prior to randomization; 2. Individuals with a history of drug or alcohol abuse within 1 year prior to randomization (definition of alcohol abuse: average daily alcohol consumption >2 units, 1 unit = 360 mL beer / 45 mL 40% vol spirits / 150 mL wine), or those who consumed alcohol-containing foods or beverages within 24 hours before administration of the study drug; 3. Individuals with psychiatric disorders (such as schizophrenia, depression, etc.) or cognitive impairment; 4. Individuals with other physical pain that may interfere with postoperative pain assessment; 5. Individuals allergic to bupivacaine, other amide local anesthetics, or the medications intended for use during the study, or with any contraindications. |
