Some studies demonstrated benefits while others concluded that there is no efficacy. Aim: the aim of the study was to compare the effect of intravenous infusion of magnesium sulfate to ketorolac during laparoscopic gynecologic oncology surgeries. Methods: We designed a double-blind randomized controlled trial that compared intravenous magnesium sulfate to ketorolac and saline solution in postoperative pain, morphine consumption and opioid related side effects.', 'detailedDescription': "Sixty American Society of Anesthesiologists (ASA) I-II patients undergoing laparoscopic gynecologic oncology surgeries are enrolled in this study.\n\nPatients were randomized to receive either intravenous ketorolac 30 mg in bolus followed by saline infusion (Group K), intravenous magnesium sulfate 20 mg/kg in bolus followed by magnesium 2 mg/kg/h (Group M) or intravenous saline solution 20 ml in bolus followed by saline infusion during the entire procedure (Group S). The study use a double-blinded methodology with random allocation into three groups using sealed opaque envelopes numbered 1 to 60, containing the instructions for the study. An independent anesthesiologist not involved in the study prepared the solutions and an observer who was also blinded to the patient's group records the data.\n\nIn the preoperative visit, patients that agree to participate are instructed about numeric rating scale (NRS) and the Patient Controlled Analgesia (PCA) device.\n\nThe night before surgery, patients are premedicated with midazolam 7.5 mg per os. Upon arrival in the operating room, monitoring devices (ECG, non-invasive arterial pressure, capnography, pulse oximetry) and a bispectral index (BIS) monitor are established. An intravenous line is secured, general intravenous anesthesia is induced with target infusion remifentanil and propofol. Cisatracurium besylate (0.5 mg/kg) is given to facilitate tracheal intubation and controlled ventilation is adjusted to maintain normocapnia with a 50% oxygen fraction administered. Then, the study medications are administered in bolus during 20 minutes, followed by continuous infusion of the specific solution, according to the study group to which the patient belonged, as described before.\n\nAt the end of the surgery, the study drugs are discontinued before the patient is extubated. If patients present clinical signs of residual neuromuscular blockade, they receive atropine 0.01mg/kg and neostigmine 0.04mg/kg. All patients receive dipyrone 30 mg/kg in bolus and a PCA device is connected to the intravenous line before discharge to the Post Anesthesia Care Unit (PACU). PCA solution containing morphine 1mg/ml in 0.9% saline, is set to give bolus of 2ml (2mg) with a 10min lockout interval.\n\nIn the postoperative period, the anesthesiologist responsible for the study question the intensity of pain in the patients using two methods: numerical rating scale (NRS) (0=no pain and 10=worst pain imaginable) and descriptive verbal scale (no pain, mild pain, moderate pain or severe pain - at emergence from anesthesia and after 20, 30 and 60 minutes, while in PACU. Patients are instructed to use the PCA device whenever they feel pain. Agitation and Sedation are monitored using RASS scale and patient is considered sedated if RASS ≤ -1. Episodes of nausea, vomiting, respiratory depression or pruritus are also recorded.\n\nPatients are discharged to the ward after 60 minutes, if minimum criteria for discharge are met.\n\nTime (in minutes) to the first morphine rescue, and total consumption of morphine in PACU are registered. After 24 hours, pain intensity score, total morphine consumption and side effects are also recorded and PCA device is disconnected."}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* ASA I-II female patients undergoing laparoscopic gynecologic oncology surgeries, for treatment of cancer\n\nExclusion Criteria:\n\n* chronic pain, cardiovascular, hepatic or renal disease, neuromuscular disease, diabetes, drugs or alcohol abuse, obesity, patients treated with calcium channel blockers or magnesium, allergy or contraindication to any of the drugs studied.'}, 'identificationModule': {'nctId': 'NCT02508857', 'acronym': 'Magnesium', 'briefTitle': 'Magnesium Sulfate Improves Postoperative Analgesia in Laparoscopic Gynecologic Surgeries', 'organization': {'class': 'OTHER', 'fullName': 'Instituto do Cancer do Estado de São Paulo'}, 'officialTitle': 'Magnesium Sulfate Improves Postoperative Analgesia in Laparoscopic Gynecologic Surgeries: a Double-blind Randomized Controlled Trial.', 'orgStudyIdInfo': {'id': 'NP0792010'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'ketorolac', 'description': 'intravenous ketorolac (30 mg) is injected in bolus, followed by continuous infusion of saline solution (Group K) during the surgical procedure', 'interventionNames': ['Drug: Ketorolac']}, {'type': 'EXPERIMENTAL', 'label': 'magnesium', 'description': 'intravenous magnesium sulfate (20 mg/kg) is injected in bolus, followed by continuous infusion of magnesium sulfate (2 mg/kg/h) (Group M) during the surgical procedure', 'interventionNames': ['Drug: Magnesium']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'saline', 'description': 'intravenous saline solution (20 ml) is injected in bolus, followed by continuous infusion of saline infusion during the entire procedure (Group S).', 'interventionNames': ['Drug: Saline solution']}], 'interventions': [{'name': 'Ketorolac', 'type': 'DRUG', 'otherNames': ['Toradol'], 'description': 'Patients received intravenous injection of ketorolac (30 mg) in bolus; then, saline solution was continuously infused during the entire procedure (Group K),', 'armGroupLabels': ['ketorolac']}, {'name': 'Magnesium', 'type': 'DRUG', 'otherNames': ['Magnesium sulfate'], 'description': 'Patients received intravenous magnesium sulfate (20 mg/kg) in bolus, then magnesium sulfate (2 mg/kg/h) was continuously injected during the procedure (Group M)', 'armGroupLabels': ['magnesium']}, {'name': 'Saline solution', 'type': 'DRUG', 'otherNames': ['Sodium chloride'], 'description': 'intravenous saline solution (20 ml) was injected in bolus, followed by continuous infusion of saline solution during the entire procedure (Group S).', 'armGroupLabels': ['saline']}]}, 'contactsLocationsModule': {'locations': [{'zip': '01403010', 'city': 'São Paulo', 'state': 'São Paulo', 'country': 'Brazil', 'facility': 'Angela Maria Sousa', 'geoPoint': {'lat': -23.5475, 'lon': -46.63611}}], 'overallOfficials': [{'name': 'angela m sousa, phD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Cancer Institute of the State of Sao Paulo'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Instituto do Cancer do Estado de São Paulo', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
