The effect of low versus high tidal volume ventilation on inflammatory markers in animal model undergoing lung ventilation: A prospective study.

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
aimsMechanical ventilation (MV) with high tidal volume (Vt.) may induce or aggravate lung injury in critically ill patients. It might also cause an overwhelming systemic inflammation leading to acute lung injury (ALI), diffuse alveolar damage (DAD) and multiple organ failure (MOF) with subsequent high mortality. The objective of this study was to compare the effects of different Vt. on the inflammatory markers of the broncho-alveolar lavage (BAL) fluid and lung biopsy in a group of animal model (Beagle dogs).
methodsA two-phased prospective study involving 30 Beagle dogs (15 dogs/phase), each phase divided into three groups (each 5 dogs/group). In the first phase each group received MV with Vt. of 8 (low), 10 (normal, control group), and 12 (high) ml/kg body weight (b.w.) respectively. BAL fluid was obtained at the time of induction of anesthesia immediately following tracheal intubation and one hour later following MV to count the macrophages, neutrophils and lymphocytes. In the second phase of the experiment, in addition to obtaining (BAL) fluid similar to the phase one, mini thoracotomy and lung biopsy obtained from the upper lobe of the right lung at same timings for histopathological examination study. Mann-Whitney-Wilcoxon test was used for statistical analysis of the data obtained.
resultsBAL fluid analysis showed increase in the counts of macrophages and lymphocytes with Vt. of 12 ml/kg b.w. compared to the control group (10 ml/kg b.w.) (
conclusionsThe use of high Vt. in ventilated animal lung model may increase the risk of inflammation and subsequent damage in healthy lungs, these findings may help physicians to avoid using high Vt. in short-term mechanically ventilated patients in the operating room setting.
