UNASSIGNED: In this randomized clinical trial, 150 patients aged 18-60 years and American Society of Anesthesiologists (ASA) physical status I who underwent lower abdomen or lower extremity surgeries with spinal anesthesia and supine position were enrolled. They were randomly divided into two groups (25 G Quincke or Sprotte needle) with 0.5% bupivacaine (12.5 mg). After the operation, the patients were asked to report any pain in the lower back, buttock, and thigh areas. A Visual Analog Scale (VAS) was also used to record the severity of the pain.
UNASSIGNED: Overall, 45 patients developed TNS. Twenty-nine patients in the Sprotte group (38.7%) and 16 patients in the Quincke group (21.3%) developed TNS (p = 0.75). More patients in the Sprotte group (25.3%) had severe pain (VAS score of 8-10) when compared with the Quincke group (6.7%). There was no significant difference in TNS symptoms duration between the two groups. In about half of patients (51.9%) in the Sprotte group and 57.3% of patients in the Quincke group, the symptoms resolved after 2-3 h.
UNASSIGNED: Although the incidence of TNS did not differ significantly, patients for whom a Sprotte spinal needle had been used had more severe pain. This suggests that the Quincke needle caused less severe pain.
■在这项随机临床试验中,纳入150例年龄在18-60岁之间的患者,以及美国麻醉师协会(ASA)的身体状况I,这些患者接受了采用脊髓麻醉和仰卧位的下腹部或下肢手术。将他们随机分为两组(25GQuincke或Sprotte针头),使用0.5%布比卡因(12.5mg)。手术后,患者被要求报告下背部的任何疼痛,臀部,和大腿区域。还使用视觉模拟量表(VAS)记录疼痛的严重程度。
■总的来说,45例患者发生TNS。Sprotte组的29名患者(38.7%)和Quincke组的16名患者(21.3%)发生了TNS(p=0.75)。与Quincke组(6.7%)相比,Sprotte组(25.3%)更多的患者出现严重疼痛(VAS评分为8-10)。两组患者TNS症状持续时间差异无统计学意义。在大约一半的患者(51.9%)在Sprotte组和57.3%的患者在Quincke组,2-3小时后症状缓解。
■虽然TNS的发病率没有显著差异,使用Sprotte脊柱穿刺针的患者疼痛更严重.这表明Quincke针引起的疼痛较轻。
