研究目的:

术后谵妄是老年髋部手术患者常见并发症,影响恢复且增加风险。右美托咪定可能预防术后谵妄,其鼻喷雾剂生物利用度高、依从性好,但其复合髂筋膜阻滞在减少该人群术后谵妄的优越性尚不明确。本研究旨在评估右美托咪定喷鼻复合髂筋膜阻滞在预防老年髋部手术病人术后谵妄的优越性和安全性。  

Objectives of Study:

Postoperative delirium is a common complication in elderly patients undergoing hip surgery, adversely affecting recovery and increasing risks. Dexmedetomidine may help prevent postoperative delirium, and its nasal spray offers high bioavailability and good compliance. However, the superiority of combining dexmedetomidine nasal spray with an iliac fascia block in reducing postoperative delirium in this population remains unclear. This study aims to evaluate the superiority and safety of dexmedetomidine nasal spray combined with an iliac fascia block in preventing postoperative delirium in elderly patients undergoing hip surgery.

干预措施:

Interventions:

组别:

第一组(神经阻滞+腰麻+右美托咪定鼻喷组)

样本量:

45

Group:

Group I (nerve block+spinal anesthesia+dexmedetomidine nasal spray group)

Sample size:

干预措施:

1.右美托咪定鼻喷:术前30分钟,给予右美托咪定鼻喷雾剂,剂量为90ug,分双侧鼻腔喷洒。 2.神经阻滞:患者取平卧位,采用超声引导下患侧髂筋膜阻滞,局麻药为0.375%罗哌卡因。 3.腰麻:神经阻滞后15-20分钟,取侧卧位,于L3-L4椎间隙穿刺,成功后注入0.5%布比卡因1.4-1.5ml(麻醉医生根据病人年龄和身高体重调整剂量),调节麻醉平面至T10以下。

干预措施代码:

Intervention:

1.Dexmedetomidine nasal spray: Thirty minutes before surgery, dexmedetomidine nasal spray was administered at a dose of 90 μg, sprayed into both nasal cavities separately. 2.Nerve block: The patient was placed in the supine position, and the ultrasound-guided ipsilateral transversus abdominis plane block (iliofascial block) was performed with 0.375% ropivacaine as the local anesthetic. 3.Spinal anesthesia: Fifteen to twenty minutes after the nerve block, the patient was placed in the lateral decubitus position, and puncture was performed at the L3-L4 intervertebral space. After successful puncture, 1.4-1.5 ml of 0.5% bupivacaine was injected (the anesthesiologist adjusted the dose according to the patient's age, height and weight), and the anesthesia plane was adjusted to below T10.

Intervention code:
