Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
control group
normal saline injection
control group
After the end of the surgery, at the arrival of PACU, the patient's leg is prepared and draped in a sterile manner. Assisted by the high-frequency linear ultrasound transducer, we target the mid-thigh level and the 22-gauge/8cm needle is introduced in plain through the sartorius muscle. the correct position for the tip of the needle in the adductor canal is checked and a bolus injection of normal saline15ml is given.
test group
0.5% ropivacaine injection
