In 2018, a new block was described, termed pericapsular nerve group block or PENG block, that selectively targets the articular branches of the femoral and obturator nerves while sparing their motor components. In this randomized trial, the investigators will compare US-guided SFIB and PENG block in patients undergoing primary THA. Since the main benefit of PENGB stems from its quadriceps-sparing effect, it was selected the incidence of quadriceps motor block (at 6 hours) as the primary outcome and the hypothesis that PENG block will result in significantly less motor block compared to SFIB.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age between 18 and 80 years\n* American Society of Anesthesiologists classification 1-3\n* Body mass index between 20 and 35 (kg/m2)\n\nExclusion Criteria:\n\n* Adults who are unable to give their own consent\n* Pre-existing neuropathy (assessed by history and physical examination)\n* Coagulopathy (assessed by history and physical examination and, if deemed clinically necessary, by blood work up i.e. platelets ≤a100, International Normalized Ratio ≥01.4 or prothrombin time ≥ 50)\n* Renal failure (assessed by history and physical examination and, if deemed clinically necessary, by blood work up i.e. creatinine ≥ 100)\n* Hepatic failure (assessed by history and physical examination and, if deemed clinically necessary, by blood work up i.e. transaminases ≥ 100)\n* Allergy to local anesthetics (LAs)\n* Pregnancy\n* Prior surgery in the corresponding side of the inguinal or suprainguinal area\n* Chronic pain syndromes requiring opioid intake at home'}, 'identificationModule': {'nctId': 'NCT04402450', 'briefTitle': 'Suprainguinal Fascia Iliaca Block Versus PENG Block for Hip Arthroplasty Analgesia', 'organization': {'class': 'OTHER', 'fullName': 'University of Chile'}, 'officialTitle': 'A Randomized Comparison Between Ultrasound-Guided Suprainguinal Fascia Iliaca Block and Pericapsular Nerve Group Block For Total Hip Replacement', 'orgStudyIdInfo': {'id': 'OAIC 1111/20'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'suprainguinal fascia iliaca block', 'description': 'Forty mL of levobupivacaine 0.25% with epinephrine 5 ug/mL will be injected cranial to the inguinal ligament between the fascia iliaca and the iliopsoas muscle.', 'interventionNames': ['Procedure: Ultrasound-guided suprainguinal fascia iliaca nerve block']}, {'type': 'EXPERIMENTAL', 'label': 'Pericapsular nerve group block', 'description': 'Twenty mL of levobupivacaine 0.5% with epinephrine 5 ug/mL will be deposited in the anterior aspect of the iliac bone between its periosteum and the tendon of the iliopsoas muscle.', 'interventionNames': ['Procedure: Ultrasound-guided pericapsular nerves group of the hip block']}], 'interventions': [{'name': 'Ultrasound-guided suprainguinal fascia iliaca nerve block', 'type': 'PROCEDURE', 'description': 'After an ultrasound-guided insertion of a block needle below the inguinal ligament, the needle will be advance in the plane between fascia iliaca and iliopsoas muscle up to a point cranial to the ligament in order to inject a 40 mL of adrenalized 0.25% levobupivacaine.', 'armGroupLabels': ['suprainguinal fascia iliaca block']}, {'name': 'Ultrasound-guided pericapsular nerves group of the hip block', 'type': 'PROCEDURE', 'description': 'After an ultrasound-guided insertion of a block needle at the level of the inguinal ligament, the needle will be advance into the plane between iliac bone periosteum and the tendon of the iliopsoas muscle in order to inject 20 mL of adrenalized 0.5% levobupivacaine.', 'armGroupLabels': ['Pericapsular nerve group block']}]}, 'contactsLocationsModule': {'locations': [{'zip': '8380456', 'city': 'Santiago', 'state': 'Metropolitan', 'country': 'Chile', 'facility': 'Hospital Clínico Universidad de Chile', 'geoPoint': {'lat': -33.45694, 'lon': -70.64827}}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO', 'description': 'unidentified data can be shared upon reasonable request after study publication'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Chile', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Assistant Professor', 'investigatorFullName': 'Julian Aliste', 'investigatorAffiliation': 'University of Chile'}}}}
