Intravenous Acetaminophen Improves Outcomes After Transapical Transcatheter Aortic Valve Replacement.

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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveComplications with opioid-based postoperative pain management have led to guideline recommendations for a multimodal analgesia strategy incorporating nonopioid agents. We evaluated the opioid-sparing effect of intravenous acetaminophen in patients undergoing transapical transcatheter aortic valve replacement.
methodsA multimodal pain management strategy that incorporated intravenous acetaminophen was retrospectively evaluated in 43 patients undergoing transapical transcatheter aortic valve replacement between November 2012 and March 2014. Before intravenous acetaminophen formulary availability, 23 patients received standard postoperative pain management interventions including intravenous narcotics and oral narcotics/acetaminophen. After intravenous acetaminophen availability, 20 patients received intravenous acetaminophen (4 g/d, ≥4 doses) and supplemental intravenous and nonacetaminophen oral narcotics. Daily narcotic dose (standardized to morphine equivalents), drug cost, and hospital length of stay were compared between groups.
resultsBaseline characteristics were similar between intravenous acetaminophen (n = 20) and nonintravenous acetaminophen (n = 23) patients including the Society of Thoracic Surgery mortality risk (10.5% vs 9.0%, P = 0.3). The median number of intravenous acetaminophen doses was 6.5 (interquartile range = 4.0-18.5), with a median cost per patient of US $221 (interquartile range = $136-$629). Patients who received intravenous acetaminophen used significantly fewer morphine equivalents on postoperative day 0 compared with patients not receiving intravenous acetaminophen (22.5 vs 45.0 morphine equivalents, P = 0.03) and had a shorter median length of stay (5.0 vs 7.0 days, P = 0.007). After adjusting for the Society of Thoracic Surgery risk, intravenous acetaminophen continued to be associated with a reduction in median postoperative length of stay [-1.9 days (95% confidence interval = -0.9 to -8.2 days), P = 0.049].
conclusionsIn patients undergoing transapical transcatheter aortic valve replacement, a multimodal pain management strategy incorporating intravenous acetaminophen was associated with reductions in narcotic use on the day of surgery and overall length of stay.
