Non-steroidal anti-inflammatory drugs (NSAIDs) are important to multimodal analgesic protocols. Parecoxib is an NSAID that selectively inhibits the enzyme cyclooxygenase-2 (COX-2). Clinical trials have shown that it does not alter platelet function or gastric mucosa. A recent study, after comparing ketorolac and parecoxib used at the same time in infiltration and systemically, found no differences in perioperative analgesia with a tendency to less bleeding in the parecoxib group. This randomized study will compare the effectiveness of adding a COX-2 inhibitor in the pain management of patients undergoing TKA as part of a multimodal analgesia regimen. The morphine consumption was selected as the primary outcome. The study hypothesis is that patients receiving parecoxib would have a lower opioid consumption.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\nASA I - III BMI 20 - 35 (kg/m2)\n\nExclusion Criteria:\n\n* Adults who are not capable of giving their own consent\n* Pre-existing neuropathy (assessed in the history and physical examination)\n* Coagulation disturbance (assessed on history and physical examination, if clinically necessary, by blood test, i.e. platelets ≤ 100,000, international normalized ratio ≥ 1.4 or prothrombin time ≥ 50)\n* Renal failure (assessed by history and physical examination, if considered clinically necessary, by blood test, i.e. creatinine ≥ 1.04 mg/dl)\n* Hepatic impairment (assessed by history and physical examination, if considered clinically necessary, by blood tests, i.e. transaminases (GGT ≥ 50 u/lt)\n* Allergy to local anesthetics, morphine, paracetamol, ketorolac or parecoxib\n* Pregnancy\n* Chronic pain syndromes that require the use of opioids at home\n* Known history of sulfa allergy\n* History of ischemic heart disease\n* History of chronic gastritis or peptic ulcer'}, 'identificationModule': {'nctId': 'NCT05924412', 'briefTitle': 'Parecoxib in Total Knee Arthroplasty', 'organization': {'class': 'OTHER', 'fullName': 'University of Chile'}, 'officialTitle': 'A Randomized Comparison Between Parecoxib and Placebo Added to a Standard Perioperative Analgesic Protocol for Total Knee Arthroplasty', 'orgStudyIdInfo': {'id': 'OAIC1308/22'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Parecoxib', 'description': 'This arm will receive intravenous parecoxib in the intraoperative period.', 'interventionNames': ['Drug: Intravenous study drug']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo', 'description': 'This arm will receive a placebo intravenous injection containing saline solution in the same volume as the intervention group', 'interventionNames': ['Other: Intravenous saline solution']}], 'interventions': [{'name': 'Intravenous study drug', 'type': 'DRUG', 'description': '40mg parecoxib will be administered intravenously after general anesthesia induction and before tourniquet inflation and surgical incisión', 'armGroupLabels': ['Parecoxib']}, {'name': 'Intravenous saline solution', 'type': 'OTHER', 'description': 'Saline solution (same volume as the study drug) will be administered intravenously after general anesthesia induction and before tourniquet inflation and surgical incision', 'armGroupLabels': ['Placebo']}]}, 'contactsLocationsModule': {'locations': [{'zip': '8380420', 'city': 'Santiago', 'state': 'Metropolitan', 'country': 'Chile', 'facility': 'Hospital Clinico Universidad de Chile', 'geoPoint': {'lat': -33.45694, 'lon': -70.64827}}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO', 'description': 'deidentified data under reasonable request'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Chile', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Associate Professor', 'investigatorFullName': 'Julian Aliste', 'investigatorAffiliation': 'University of Chile'}}}}
