Laboratory evaluation of the Go Medical PCI: a disposable patient-controlled analgesia device

Anaesth Intensive Care. 1993 Apr;21(2):204-7. doi: 10.1177/0310057X9302100213.


A low-cost, disposable patient-controlled analgesia device was tested using a computer-controlled, automated testing station designed to simulate clinical use. Five devices were tested and delivered a mean bolus dose size of 95% of nominal, although one device achieved only 85% of nominal. Delivery was lowest immediately following an eight-hour interval during which no demands were made. Further development and evaluation of this interesting device is warranted.
