Peritoneal instillation of taurolidine or polihexanide modulates intestinal microcirculation in experimental endotoxemia.
Article in International journal of colorectal disease, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
aimsTreatment of peritonitis may include peritoneal lavage/instillation with anti-infective agents like taurolidine or chlorhexidine. MATERIALS AND
methodsWe examined the effects of peritoneal instillation (INST, 5-ml solution) with taurolidine (TAURO) or polihexanide (POLI-LS) on intestinal microcirculation using intravital microscopy (IVM) in experimental endotoxemia (15 mg/kg lipopolysaccharide i.v.; LPS) in the rat (n = 8 each group), their direct effects on local small blood vessels, aortal rings, and myocardial strips in vitro, as well as plasma interleukin levels.
resultsIt was found that LPS produced hypotension (98.8 +/- 9.5 vs 130.4 +/- 10.5 mmHg; mean arterial pressure [MAP], mean +/- standard deviation [SD]), which was further pronounced after INST of TAURO (78.8 +/- 10.8; P < 0.005) or POLI-LS (78.1 +/- 6.0; P < 0.001). IVM revealed a reduction in temporary adhering leucocytes and an increase in firmly adhering leucocytes after INST with TAURO and POLI-LS. Both agents reduced functional capillary density either in the mucosa (POLI-LS vs sham: 259.7 +/- 54 cm/cm(2) vs 337.1 +/- 35.5) or longitudinal muscular layer in LPS rats (TAURO vs sham: 119.8 +/- 14.8 vs 153.7 +/- 11.0). POLI-LS induced local vasodilatation, whereas TAURO induced small vasoconstriction; in vitro, both agents showed vasodilating properties and did not have any effect on myocardial strip contraction.
conclusionSome of the observed microcirculatory changes could be a result of the direct vascular effects of these agents.
