High-performance liquid chromatographic analysis of doxacurium, a new long-acting neuromuscular blocker.
A rapid and sensitive high-performance liquid chromatographic procedure was developed for the analysis of the new, long-acting neuromuscular blocker doxacurium in the plasma and urine of dog and man and in the bile of dog. Samples were prepared on solid-phase extraction cartridges containing a methyl (C1) bonded phase and were chromatographed on a 15 cm reversed-phase column (C1) using a mobile phase of 0.05 M monobasic potassium phosphate-acetonitrile (30:70, v/v). The compound was detected at 210 nm with a lower limit of quantitation of 10 ng/ml. An inter-assay accuracy of 90-92% was obtained for the analysis of the drug from biological fluids. The method was applied to studies of doxacurium after intravenous administration to dog and man.

Hypokalemia.
Hypokalemia is an electrolyte imbalance that can have serious effects on the patient if not detected early. Therefore, it is important for the nurse to: (1) be aware of those patients at risk for excess potassium loss, (2) monitor those patients' ECG to observe for any changes indicative of hypokalemia, and (3) assess for physical signs and symptoms indicative of hypokalemia. Early detection of hypokalemia and early intervention will prevent potential catastrophic events.
