The ProSeal™ LMA (PLMA™) is a specialized type of LMA with a design that permits the delivery of higher pressures to help the patient breathe in and out (ventilate) and also contains a channel to suction the stomach.\n\nChildren under GA may breathe through a PLMA in different ways. Spontaneous ventilation consists of the children breathing on their own through a PLMA™. Pressure support ventilation allows the patient to breathe on their own with additional help from the anesthesia machine. Pressure control ventilation allows the patient to breathe with the help of an anesthesia machine.\n\nA child undergoing surgery requires a deep level of general anesthesia which negatively affects their ability to ventilate. Thus, children may not breathe in oxygen and carbon dioxide out adequately at this level of anesthesia and it may be beneficial to provide some level of support to enhance carbon dioxide exchange and to avoid hypoventilation.\n\nThis study will attempt to determine whether pressure support ventilation improves ventilation in children undergoing outpatient surgery.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '5 Years', 'minimumAge': '12 Months', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* ASA physical classification 1,2 (Healthy or relatively healthy children)\n* Subjects scheduled for outpatient surgical procedures.\n* Surgical procedure anticipated to be \\< 90 minutes\n* Subject weight of ≤ 20 kg (44 lbs)\n* Subject age of 12 months to 5 years (inclusive)\n\nExclusion Criteria:\n\n* Inpatient\n* ASA physical classification of 3, 4 or E (sick children)\n* Risk of aspiration\n* Subjects with malignant hyperthermia or family history of malignant hyperthermia\n* Subjects with tracheostomies'}, 'identificationModule': {'nctId': 'NCT00966433', 'briefTitle': 'A Comparison of Different Ventilation Strategies in Children Using the Proseal™ Laryngeal Mask Airway', 'organization': {'class': 'OTHER', 'fullName': 'Wake Forest University Health Sciences'}, 'officialTitle': 'A Comparison of Different Ventilation Strategies in Children Using the Proseal™ Laryngeal Mask Airway', 'orgStudyIdInfo': {'id': 'IRB00009452'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Spontaneous ventilation', 'description': "Pt's will be allowed to breathe spontaneously through the PLMA during surgery without the assistance of positive pressure ventilation.", 'interventionNames': ['Procedure: Spontaneous ventilation']}, {'type': 'EXPERIMENTAL', 'label': 'Pressure support ventilation', 'description': "Pt's will receive positive pressure assistance with each spontaneous breath through the PLMA.", 'interventionNames': ['Device: Pressure support Ventilation']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Pressure control ventilation', 'description': "Pt.'s will be placed on the ventilator and ventilated with pressure control. through the PLMA.", 'interventionNames': ['Device: Pressure control ventilation']}], 'interventions': [{'name': 'Spontaneous ventilation', 'type': 'PROCEDURE', 'description': 'The patient will breathe spontaneously (on their own)while under general anesthesia throughout the duration of the surgery.', 'armGroupLabels': ['Spontaneous ventilation']}, {'name': 'Pressure support Ventilation', 'type': 'DEVICE', 'description': 'The patient will breathe on their own and with a little assistance from the anesthesia machine while under general anesthesia throughout the duration of the surgery.', 'armGroupLabels': ['Pressure support ventilation']}, {'name': 'Pressure control ventilation', 'type': 'DEVICE', 'description': "The patient's ventilation will be completely supported by the anesthesia machine while under general anesthesia throughout the duration of the surgery.", 'armGroupLabels': ['Pressure control ventilation']}]}, 'contactsLocationsModule': {'locations': [{'zip': '27157', 'city': 'Winston-Salem', 'state': 'North Carolina', 'country': 'United States', 'facility': 'Wake Forest University Health Sciences', 'geoPoint': {'lat': 36.09986, 'lon': -80.24422}}], 'overallOfficials': [{'name': 'Thomas W Templeton, M.D.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Wake Forest University Health Sciences'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Wake Forest University Health Sciences', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
