研究目的: |
之前的研究已经证明,阴部神经阻滞是一种有效的麻醉技术,可以减少年轻男性包皮环切术和尿道下裂患者的镇痛消耗,延长术后镇痛时间。 解剖学上,尿道和膀胱三角的传入神经来自骶体神经(S2–S4段),理论上,预防导尿管相关膀胱不适和膀胱痉挛应通过阻断这些神经来实现。阴部神经是会阴部的主要神经,来自第二、第三和第四骶脊神经的腹支;支配尿道括约肌、会阴和盆底肌肉;并为男性阴茎和女性阴蒂以及尿道和膀胱三角提供感觉。本研究比较了在腰麻下行前列腺电切术中,地塞米松和地塞米松联合右美托咪定作为神经周围佐剂的阴部神经阻滞的效果,主要结果是阴部神经的有效时间,从阴部神经阻滞给药完成到感觉恢复(≥5分)的时间。次要结果包括局麻药注射后6h、9h、12h、16h、24h、36h、48h的疼痛评分和CRBD评分,以及术后三天膀胱痉挛的发生率和亚症状评分。 |

Objectives of Study: |
Previous studies have proved that pudendal nerve block is an effective anesthetic technique, which can reduce the analgesic consumption of young male patients with circumcision and hypospadias, and prolong the postoperative analgesic time. Anatomically, the afferent nerves of the urethra and bladder triangle come from sacral somatic nerves (S2 – S4 segments), and theoretically, the prevention of catheter-related bladder discomfort and bladder spasm should be achieved by blocking these nerves. The pudendal nerve is the main nerve in the perineum, which comes from the abdominal branches of the second, third and fourth sacral spinal nerves; Innervate urethral sphincter, perineal and pelvic floor muscles; It also provides sensation for male penis and female clitoris as well as urethra and bladder triangle. This study compared the effect of dexamethasone and dexamethasone combined with dexmedetomidine as perineural adjuvant pudendal nerve block in transurethral resection of the prostate under spinal anesthesia. The main result was the effective time of pudendal nerve, and the time from the completion of pudendal nerve block administration to sensory recovery (≥ 5 points). Secondary outcomes included pain scores and CRBD scores at 6h, 9h, 12h, 16h, 24h, 36h, 48h after local anesthetic injection, as well as the incidence and Subsymptomatic scores of bladder spasm three days after operation. |

随机方法(请说明由何人用什么方法产生随机序列): |
采用计算机生成的随机数字表,将入选患者按1:1的比例随机分为两组:罗哌卡因+地塞米松(RS)组和罗哌卡因+地塞米松+右美托咪定(RSM)组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Using a computer-generated random number table, the enrolled patients were randomly divided into two groups in a 1:1 ratio: the ropivacaine+dexamethasone(RS)group and the ropivacaine+dexamethasone+dexmedetomidine(RSM)group. The grouping results were sealed in an opaque envelope and saved by research managers. On the day of surgery, the research manager handed the envelope to the assistant anesthesiologist to prepare the local anesthetic test solution. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
数据的收集均由病房护士和主管医生收集并记录,冰块试验由麻醉医生完成并收集数据。最后由主要研究者进行电子数据的归纳、录入、统计和分析。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
The data were collected and recorded by ward nurses and doctors in charge, and the ice test was completed and collected by anesthesiologists. Finally, the main researchers summarize, input, count and analyze the electronic data. |
