研究组 & 干预措施
Subgluteal Sciatic Nerve Block
Patients randomized to this group will receive a sciatic nerve block with the catheter tip insertion at the subgluteal location 1-3 cm caudad to the inferior border of the gluteus maximus muscle.
干预措施: Subgluteal Sciatic Nerve Block (Procedure)
Popliteal Sciatic Nerve Block
Patients randomized to this group will receive a sciatic nerve block with the catheter tip insertion at the popliteal location 1-3 cm cephalad to the sciatic bifurcation.
干预措施: Popliteal Sciatic Nerve Block (Procedure)
结局指标
主要结局
Muscle Strength (MVIC) of the hamstring muscles
时间窗: 08:00-09:00 morning after surgery as a percentage of baseline
We will evaluate hamstring strength which is innervated by the sciatic nerve with an isometric force electromechanical dynamometer to measure the force produced during a maximum voluntary isometric contraction (MVIC) in a seated position with the knees flexed at 90º
次要结局
- Sensory Effect(08:00-09:00 morning after surgery)
- Pain Scores(from leaving the PACU until 08:00 the morning after surgery)
- Sleep Disturbances(recorded at 08:00-09:00 the morning after surgery for the previous night)
- Total Infusion(recorded at 08:00-09:00 the morning following Surgery)
- Anesthetic Leakage(recorded at 08:00-09:00 the morning following Surgery)
- analgesic consumption(end of PACU stay until 08:00-09:00 the morning following surgery)
