Medications most commonly used to control for post-operative pain are opioid medications, whose well known adverse effects include PONV. Currently, no studied adequate alternative to opiates exists for mild-moderate pain relief without the aforementioned risks.\n\nThe primary goal for this study is to evaluate the the administration of pre- and post-operative IV acetaminophen to determine if there is in an overall decrease in the use of opioid analgesics by patient controlled analgesia (PCA) and subsequent decrease in subjective PONV leading to sooner return of bowel function, enabling progression to oral intake and decrease in post-operative length of stay.', 'detailedDescription': 'Opioid use during the post-operative period is a highly effective means of treatment for acute pain, however not without its adverse effects including post-operative nausea, vomiting (PONV), constipation, urinary retention, sedation and respiratory depression. Such factors have been implied in the literature to contribute to prolonged post-operative length of stay, delayed return to diet, return of bowel function and increased incidence of ileus. Alternatively, non-opioids, such as acetaminophen, aspirin, NSAIDs, and selective cyclo-oxygenase-2 inhibitors, can be utilized for acute pain, either alone or in combination with opioids. In the bariatric post-surgical population, NSAIDS both oral and IV (Toradol, Ibuprofen) are not recommended due to their potential bleeding tendency, anti-inflammatory effect, and ulcerogenic effect.\n\nThe LRYGBP may be classified as a surgery type associated with mild to moderate post-operative pain. Therefore, the mode of pain relief could directly affect the length of stay. The advent of IV acetaminophen serves as a opportunity to investigate in detail the efficacy of this non-opioid medication in the management of acute pain in the immediate post-operative period without the aforementioned adverse effects as expected from traditional opiate medications. A comprehensive approach to this study includes a prospective, double-blinded, randomized controlled trial of subjects who will undergo LRYGBP and randomized to the study agent (IV acetaminophen) or placebo.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* patients who are scheduled to undergo laparoscopic Roux-en-Y gastric bypass surgery (LRYGBP) under general anesthesia.\n* age 18 to 65 years\n* BMI \\>35\n* ASA scores 1,2, or 3\n* a negative pregnancy test for female subjects of childbearing age\n* ability to read, understand and provide informed consent to the study procedures\n* ability to read and understand the use of pain and nausea scales (VAS)\n\nExclusion Criteria:\n\n* known hypersensitivity to acetaminophen or opioids\n* use of opioid or schedule II medications prior to commencement of the study \\>7 days\n* those with chronic pain conditions or significant medical disease requiring pain control\n* abnormal liver function (aspartate aminotransferase/alanine aminotransferase/bilirubin \\> 3X upper limit of normal range, active hepatic disease, clinically significant liver disease, cirrhosis or hepatitis)\n* known or suspected alcohol, drug or opiate abuse or dependence; or participation in other clinical study within 30 days of surgery.'}, 'identificationModule': {'nctId': 'NCT01460667', 'acronym': 'IV APAP', 'briefTitle': 'Efficacy of IV Acetaminophen in Acute Post-Operative Pain Control in Laparoscopic Roux-en-Y Gastric Bypass Surgery (LRYGBP) Patients', 'organization': {'class': 'OTHER', 'fullName': 'McLaren Regional Medical Center'}, 'officialTitle': 'A Randomized, Double-Blind, Placebo-Controlled, Single Center Study of IV Acetaminophen for the Treatment of Post-Operative Pain After Laparoscopic Roux-en-Y Gastric Bypass Surgery (LRYGBP)', 'orgStudyIdInfo': {'id': 'IV APAP LRYGBP Study'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'IV acetaminophen', 'interventionNames': ['Drug: IV acetaminophen']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'IV 0.9% normal saline', 'interventionNames': ['Drug: IV normal saline']}], 'interventions': [{'name': 'IV acetaminophen', 'type': 'DRUG', 'description': 'IV acetaminophen 1000 mg (100 mL) every 6 hours over 30 hours', 'armGroupLabels': ['IV acetaminophen']}, {'name': 'IV normal saline', 'type': 'DRUG', 'description': '0.9% normal saline IV, every 6 hours over 30 hours.', 'armGroupLabels': ['IV 0.9% normal saline']}]}, 'contactsLocationsModule': {'locations': [{'zip': '48532', 'city': 'Flint', 'state': 'Michigan', 'status': 'RECRUITING', 'country': 'United States', 'contacts': [{'name': 'Christina Lee, B.Sc.', 'role': 'CONTACT', 'email': 'leechr28@msu.edu', 'phone': '517-505-4640'}, {'name': 'Christina Lee, B.Sc.', 'role': 'SUB_INVESTIGATOR'}, {'name': 'Michael Kia, D.O.', 'role': 'PRINCIPAL_INVESTIGATOR'}], 'facility': 'McLaren Regional Medical Center', 'geoPoint': {'lat': 43.01253, 'lon': -83.68746}}], 'centralContacts': [{'name': 'Christina Lee, B.Sc.', 'role': 'CONTACT', 'email': 'leechr28@msu.edu', 'phone': '517-505-4640'}], 'overallOfficials': [{'name': 'Christina Lee, B.Sc.', 'role': 'STUDY_DIRECTOR', 'affiliation': 'McLaren Regional Medical Center'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'McLaren Regional Medical Center', 'class': 'OTHER'}, 'collaborators': [{'name': 'Cadence Pharmaceuticals', 'class': 'INDUSTRY'}], 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Study Coordinator, McLaren Regional Medical Center', 'investigatorFullName': 'Christina Lee', 'investigatorAffiliation': 'McLaren Regional Medical Center'}}}, 'annotationSection': {'annotationModule': {'unpostedAnnotation': {'unpostedEvents': [{'date': '2017-04-15', 'type': 'RELEASE'}, {'date': '2017-05-23', 'type': 'RESET'}, {'date': '2017-08-08', 'type': 'RELEASE'}, {'date': '2017-09-08', 'type': 'RESET'}], 'unpostedResponsibleParty': 'Michael Kia, Dr. Michael Kia, McLaren Regional Medical Center'}}}}
