Comparıson Of PENG Block wıth Intra-articular And Quadratus Lumborum Block İn Primary Total Hip Arthroplasty

Opioid consumption

Analgesic consumption

Time frame: 3-6-8-12-24 and 48 hours

Static and dynamic pain

Pain intensity at rest and during active movement using a numeric rating score (NRS) 0 = no pain and 10 = worst imaginable painranged from 0 to 10

Time frame: 3-6-8-12-24 and 48 hours

Presence of quadriceps motor block (defined as paralysis or paresis )

Quadriceps motor function will be tested with the patient supine and with the hip and knee flexed at 45º and 90º, respectively. The subject will be asked to extend the knee first against gravity and then against resistance. Quadriceps strength will be graded according to a 3-point scale: normal strength = 0 point (extension against resistance); paresis = 1 point (extension against gravity but not against resistance); and paralysis = 2 points (no extension).

Time frame: 3-6-12-24 hours after the block

Hip adduction strength

Hip adduction will be evaluated by comparing it to baseline strength (i.e., prior to spinal anesthesia). A blood pressure cuff, inflated at 40 mmHg, will be inserted between the knees of the patient: the latter will then be instructed to squeeze the cuff as hard as possible and to sustain the effort. We will define hip adduction scores of 0, 1 and 2 points as decreases in strength of 0-20%, 21-70% and 71-90% compared to baseline measurement, respectively

Time frame: 3-6-12-24 hours after the block

Presence of postoperative nausea, vomiting, pruritus, urinary retention, respiratory depression
