If you can do a lumbar tap you can do this procedure. However, you must be able to deal with the possible complications if they should arise. You can make up your own tray, but the pre-prepared sets are convenient and my hospital says they are cost effective.
Sets come with disinfectant solution included.
Does not affect uterine arterial flow. Note that the mild hypotension that can occur is usually treated easily by a fluid bolus and by positioning the patient in the left lateral position. Dose, 0.2 mg. May have to be repeated as it has a short half-life compared to the narcotics. Used for respiratory depression, pruritis or severe nausea.
