Intravenous loading of nitroglycerin during rewarming of cardiopulmonary bypass improves metabolic homeostasis in cardiac surgery: a retrospective analysis.
Article in Journal of anesthesia, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeThe aim of the study was to evaluate the effects of high-dose nitroglycerine (NTG) on glucose metabolism, tissue oxygenation and postoperative recovery in cardiac surgical patients.
methodsCardiac surgical patients in the retrospective survey were classified into two groups based on the NTG regimen. NTG group had intravenous loading of NTG (infusion rate 10-20 mg/h with total dose of ≥0.5 mg/kg) starting at rewarming of cardiopulmonary bypass (CPB) (n = 101), and control group had no intravenous loading of NTG (n = 151). Data for intraoperative plasma glucose and lactate levels, and regular insulin consumption were collected. Propensity score methodology was utilized to adjust for potential confounders.
resultsAfter adjustment for propensity score, the plasma glucose was significantly lower in the NTG group during (161 ± 39 versus 179 ± 45 mg/dl, p = 0.005) and after CPB (167 ± 41 versus 184 ± 48 mg/dl, p = 0.012). Total consumption of regular insulin was significantly lower in the NTG group, median 8 (range 0-50) versus 13 (0-90) international units, p = 0.005. There was a trend towards statistical significance in a lower incidence of hyperlactatemia (>2.2 mmol/l) in the NTG group during CPB, 21/100 (21 %) versus 40/132 (30.3 %), p = 0.065. The mixed venous oxygen saturation in the intensive care unit was higher in the NTG group, 65 ± 9 versus 62 ± 11 %, p = 0.056.
conclusionsIntravenous loading of NTG during and after CPB is safe and effective for attenuating the hyperglycemic response and reduce the incidence of hyperlactatemia during cardiac surgery with CPB.
