Introduction and Clinical Question My current position is a clinical lead nurse on a surgical/orthopedic floor, we receive a wide variety of patients with a large concentration of them being post-operative knee or hip replacements. Over the last year and a half our surgeons and anesthesiologists have implemented the use of continuous peripheral nerve blocks (CPNB), often referred to as pain pump balls, specifically we use the OnQ balls. “The On-Q infusion device is an elastomeric device with a flow regulator that controls the flow of a local anesthetic agent through a peripheral catheter” (Burnett, 2011). The pain pump balls are intended to decrease post-op pain and maximize patient’s ability to participate in physical therapy. The…show more content…
I then switched to a more specific database, CINAHL and used keywords: nerve, block, continuous and received over 170 results. It is rather difficult to find raw data, such as an individual set of vitals or pain assessment, that has not already been interpreted and put to theory but, data regarding the pumps themselves were made easily accessible. OnQ states their pumps are filled with 550 mls of the anesthetic and set to a standard flow rate of 6 mls per hour (Postoperative pain, 2016). By using this data and determining how many hours the pump will last the patient then becomes meaningful and then considered information. Information The information section of the continuum is where data is put in context. One of the studies I came across found that “with the use of CPNB’s pain scores were significantly lower at the 12 hours postoperative time point (P = 0.002) and at 2 weeks postoperatively” (Ding, 2015). There were also studies that looked at how the use of CPNB’s expedited the process of rehabilitation stating “with the block there was a noted decrease in the time until adequate mobilization” (Machi, 2015). A study of 155 post-op joint replacement patients looked specifically at pain scale ratings before and during therapy, they found that “overall, baseline ‘at rest’ as well as ‘with activity’ pain scores were less in the group with continuous nerve block,” and “mean opioid consumption was significantly less in those patients[with CPNB’s]” (Ardon,
