The Efficacy of Patient-Controlled Analgesia

1438 Words3 Pages

The practice of patient-controlled analgesia (PCA) has been around for approximately four decades now. During this time there have been improvements to the technology and the understanding of how to use this form of patient pain control; however, there continues to be concern related to the safety and efficacy of PCA. As this analysis proceeds it will briefly explain what PCA is and how it is used, then delve into the benefits and the safety issues surrounding PCA use as it pertains to the patient and the nurse. Some of the benefits of PCA include improved pain management, improved use of nursing resources, increased patient satisfaction, and reduced pulmonary issues (Hicks, Sikirica, Nelson, Schein & Cousins, 2008). Some of the safety issues surrounding PCA use include infusion pump programing errors, basal infusion dosing, and proxy errors when using PCA by proxy (Ladak, Chan, Easty, & Chagpar, 2007). Therefore, the purpose of this report is to examine the benefits and risks of patient-controlled analgesia and how it relates to nursing practice.

Patient-controlled analgesia by way of an infusion pump allows patients experiencing moderate to severe pain as a result of surgery, trauma, cancer, and other chronic conditions, to administer their own pain medication. The most common type of medication used in infusion pumps today are opioid analgesics, because of their effectiveness and availability (Chumbley & Mountford, 2010). PCA infusion pumps provide the analgesia via intravenous or epidural routes allowing for almost instantaneous pain relief verses the delay in having the nurse prepare and administer each dose as needed. These pumps allow analgesia to be delivered with a basal (background) infusion rate, a bolus (pati...
