1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

backgroundEffective pain management following total knee arthroplasty (TKA) is fundamental in achieving positive rehabilitation outcomes. The purpose of our study was to investigate post operative pain management in relation to short term functional mobility in an intervention group receiving concomitant use of an IV narcotic PCA and a continuous infusion of local anaesthetic via a femoral nerve catheter (CFNC), compared to a group receiving narcotic PCA alone. This was a preliminary study conducted to establish an appropriate design for a larger investigative study.

methodsA prospective design was used to measure the effect of a CFNC on post operative pain management and functional mobility prior to hospital discharge. The amount of fentanyl used, pain and nausea scores, timed up and go (TUG) tests and active range of knee movement (AROM) were used to compare a CFNC and supplemental narcotic patient controlled analgesia (PCA) group (n = 27) with a PCA only group (n = 25).

resultsThe CFNC group used significantly less fentanyl than the PCA only group (p < .001) but there was no significant difference in TUG times between the two groups. There was however a significantly lower AROM reported for both extension (p < .04) and flexion (p < .006,) in the FNC group. Women had significantly slower TUG times (p < .005,) and there were moderate to strong positive correlations between post operative TUG times and the preoperative TUG time (r(s) = .505 p < .001), the time since oral analgesia (r(s) = .529 p < .014), and pain scores (r(s) = .328, p = .034)

conclusionsIn this small preliminary study improved TUG performance at Day 4 post op was not influenced by the use of a CFNC but was positively correlated with male gender, preoperative performance, time elapsed since last oral analgesia and pain score. However AROM was decreased in the CFNC group suggesting further research on the relationship between CFNCs, local anaesthetic concentration and quadriceps strength should be incorporated in the follow up study's design.
