Some of the newer high-technology infusion devices commercially available or under development are described. The range of infusion devices includes both controllers and pumps; pumps can be classified by mechanism of operation (peristaltic, syringe, cassette, elastomeric reservoir), frequency or type of drug delivery (continuous or intermittent infusion, bolus dosing, single- or multiple-solution delivery), or therapeutic application (such as the patient-controlled analgesia, or PCA, pump). ⋯ Current research in infusion-device technology is focusing on implantable pumps, pumps with chronobiological applications, osmotic-pressure devices, and open- and closed-loop systems. Pharmacists need to keep abreast of the rapidly changing intravenous device marketplace to provide clinical expertise and leadership in the review and evaluation of high-technology drug delivery systems.

The pharmacist's role in the implementation of patient-controlled analgesia (PCA) in a 400-bed community hospital is described. PCA for postoperative patients was introduced on the recommendation of the pharmacy and therapeutics committee. A subcommittee selected a PCA pump, developed a physician order form and patient monitoring sheet, and in March 1987 initiated a two-month pilot study of PCA therapy in orthopedic-surgery patients. ⋯ Pharmacists in the decentralized areas also provided one-on-one instruction to physicians, nurses, and patients. Positive evaluations of PCA therapy by patients and nurses and favorable patient pain assessment scores, in addition to the hospital-wide acceptance and use of PCA by medical staff, indicated that the program was a success. Active pharmacist participation was a major factor in PCA being well accepted by physicians, nurses, and patients as an effective alternative method of narcotic administration.
