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.
Dual cannula tubes are inherently safer as the inner cannula may be removed quickly in the event of obstruction and are therefore preferred for patients who continue to require a tracheostomy tube after discharge from the hospital. Tubes with inner cannulas should be used, when possible. The inner cannula should be removed, cleaned, and reinserted at regular intervals. The frequency of these changes depend on individual patientsâ requirements as determined by the volume and viscosity of secretions.
