Patient-controlled analgesic infusion pumps

We evaluated seven PCA infusion pumps from seven manufacturers. The condition for acceptable use of six of the units was that they not be used at low volumes that could result in overinfusion from the stored volume when an occlusion is cleared. Our ratings and ranking were based primarily on safety, security, and overall ease of use. All pumps met most accuracy, electrical safety, and performance criteria. Two of the pumps were suitable for ambulatory use but were not recommended for general hospital or home care bedside use. One of the pumps was totally disposable and nonelectronic.
