The women were enrolled prospectively in separate, sequential, nonrandomized clinical trials and treated with nystatin vaginal suppository at 20 MU per day for 7 days or two 1,200-mg doses of miconazole vaginal suppositories 72 hours apart or oral fluconazole two 150-mg doses 72 hours apart or oral itraconazole 200 mg two times for 1 day.
A cannula needle is a stainless steel, hollow needle encased by a hollow plastic tube. The needle closely resembles a medical syringe tip, except that the needle isn't always attached to a plastic barrel for extracting fluids or tissue.
The flexible cannula may or may not be radio-opaque. Some cannula hubs possess suture wings to allow the cannula to be sutured in place, some have small wings that can be stuck in place and others have no wings at all. In addition, some arterial cannulae possess an 'on/off' switch on the cannula hub to open and close the catheter lumen.
