Ephedrine In Obstetrics

Atropine and ephedrine adsorption

The purpose of this study was to compare daily changes in the concentration of atropine or ephedrine sulfate solutions that had been stored up to 4 days in plastic or glass syringes. Sets of three plastic and one glass syringe were used for each drug; the glass syringes acted as controls. Each set of syringes was labeled as day 0, 1, 2, 3, or 4. Syringes with medication were laid horizontally, ...

Biotransformation for L-ephedrine production.

L-ephedrine is widely used in pharmaceutical preparations as a decongestant and anti-asthmatic compound. One of the key intermediates in its production is L-phenylacetylcarbinol (L-PAC) which can be obtained either from plants (Ephedra sp.), chemical synthesis involving resolution of a racemic mixture, or by biotransformation of benzaldehyde using various yeasts. In the present review, recent s...

Intraoperative neuromonitoring in cardiac surgical patients with severe cerebrovascular disease.

hypotension occurs during spinal anesthesia. Only one prior case has been published describing profound hypotension in a parturient with bipolar disease, controlled with lithium and risperidone, undergoing spinal anesthesia for Cesarean delivery. The patient was refractory to conventional treatment with ephedrine and iv fluids, and eventually responded to large doses of phenylephrine.2 The trea...
