指标类型:

主要指标

Outcome:

Degree of adductor muscle strength reduction

Type:

Primary indicator

测量时间点:

阻滞前(T0)阻滞后3 min(T1)、10 min(T2)、20 min(T3)

测量方法:

穿刺开始前将带有压力表的加压带增压到初始值100mmHg,将加压带置于患者两膝之间,嘱患者两腿内收挤压加压带,以最大压力和初始值(100mmHg)之间的差值反映患者大腿内收肌肌力(记为P1),超声引导下闭孔神经阻滞完成后3min、10min、20min以同样的方法检测大腿内收肌的肌力(分别记为P2、P3、P4),将(P1-P4)/( P1)*100%记为内收肌肌力减弱程度

Measure time point of outcome:

Before block, and at 3 min, 10 min, and 20 min after block

Measure method:

Prior to needle insertion, the pressure cuff with a manometer was inflated to an initial value of 100 mmHg. The cuff was placed between the patient's knees, and the patient was instructed to adduct both legs to compress the cuff. The difference between the maximum pressure and the initial value (100 mmHg) was recorded as the baseline adductor muscle strength (denoted as P1).At 3 min, 10 min, and 20 min after ultrasound-guided obturator nerve block, adductor muscle strength was reassessed using t
