Pharmacy-initiated implementation of a syringe pump infusion system.

The approach taken by a pharmacy department of a 310-bed community hospital to evaluate and implement a syringe infusion pump system is described. The cost of the minibag system used by the hospital was compared with the cost of the syringe system. A trial of the system involving three medications was implemented in two patient-care areas. After a six-week period, nurses favored expansion of the new system. After a detailed cost comparison was presented to hospital administration, hospitalwide conversion to the new system was approved. Groups of drugs were gradually added to the dispensing list. At the end of a five-month period, 80% of secondary intravenous medications were administered via the new system. Advice is offered to other hospitals considering the system. A smooth transition to a syringe infusion system was the result of the well-planned approach.

Costs and Cost Analysis

Variability of oxygen affinity of normal blood: an automated method of measurement.

Oxygen equilibrium curves of 48 healthy adult subjects have been measured by the method of Rossi-Bernardi et al. (Clin. Chem. 21: 1747, 1975), in which H2O2 is gradually added to a sample of deoxygenated blood that contains an excess of catalase. The mean P50 for nonsmokers was 26.9 Torr and the distribution of values was slightly skewed to the right (range 24.2--29.9 Torr). The method differs from others previously available in that pH, PCO2, and HCO3-- are constant during oxygenation. The system for control of the experiment and data collection and processing has been automated by the use of a microprocessor so that the equilibrium curve can be obtained quickly, reproducibly, and relatively simply. With the aid of a digital computer, the parameters of the generalized Adair equation can also be estimated.
