Randomized Trial of Concomitant Maze Procedure Using Nitrous Oxide Versus Argon-Based Cryoablation.

Summary of "Randomized Trial of Concomitant Maze Procedure Using Nitrous Oxide Versus Argon-Based Cryoablation."

Currently, two types of cryoprobes are available: NO-based and argon gas-based. However, few studies have compared the outcomes obtained with these two cryoprobe types. The aim of this study was to compare the early outcomes of a concomitant maze procedure using NO-based cryoablation (the NO group) versus argon gas-based cryoablation (the Argon group) in patients with persistent atrial fibrillation (AF).

Medical and Biotech [MESH] Definitions

Nitrogen oxide (N2O). A colorless, odorless gas that is used as an anesthetic and analgesic. High concentrations cause a narcotic effect and may replace oxygen, causing death by asphyxia. It is also used as a food aerosol in the preparation of whipping cream.

Work consisting of a clinical trial that involves at least one test treatment and one control treatment, concurrent enrollment and follow-up of the test- and control-treated groups, and in which the treatments to be administered are selected by a random process, such as the use of a random-numbers table.

Work consisting of a clinical trial involving one or more test treatments, at least one control treatment, specified outcome measures for evaluating the studied intervention, and a bias-free method for assigning patients to the test treatment. The treatment may be drugs, devices, or procedures studied for diagnostic, therapeutic, or prophylactic effectiveness. Control measures include placebos, active medicine, no-treatment, dosage forms and regimens, historical comparisons, etc. When randomization using mathematical techniques, such as the use of a random numbers table, is employed to assign patients to test or control treatments, the trial is characterized as a RANDOMIZED CONTROLLED TRIAL.

Learning the correct route through a maze to obtain reinforcement. It is used for human or animal populations. (Thesaurus of Psychological Index Terms, 6th ed)

Works about a study where participants are assigned to a treatment, procedure, or intervention by methods that are not random. Non-randomized clinical trials are sometimes referred to as quasi-experimental clinical trials or non-equivalent control group designs.
