Chewing gum to treat postoperative nausea and vomiting in female patients: a multicenter randomized trial.

Background: Postoperative nausea and vomiting (PONV) is common after general anesthesia, with consequences for patient outcomes, satisfaction with care and healthcare costs. Our aim was to compare a new treatment, chewing gum, with a widely-used intravenous agent, ondansetron, to treat PONV in female patients in the post anesthesia care unit (PACU).

Methods: We conducted a multicenter, randomized, controlled non-inferiority trial in 17 hospitals in Australia and New Zealand.

Designing a breast support device for phase contrast tomographic imaging: getting ready for a clinical trial.

Objective: To design a device that can support the breast during phase-contrast tomography, and characterise its fit parameterisation and comfort rating.

Methods: 27 participants were recruited to trial a system for breast support during simulated phase contrast imaging, including being positioned on a prone imaging table while wearing the device. Participants underwent a photogrammetry analysis to establish the geometric parameterisations.
