Analysis of flow rate of continuous bladder irrigation according to the height of the irrigation infusion set.
Article in Scientific reports, 2023. 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
This is a control volume analysis to examine the flow rate of irrigation fluid according to the size of indwelling catheter and the height of the fluid bag in consideration of the temperature of irrigation fluid and intra-bladder pressure during continuous bladder irrigation. In case of minimum bladder pressure with room temperature, the flow rates were - 0.045 to 0.993 cc/sec for 18Fr, - 0.053 to 1.176 cc/sec for 20Fr, - 0.055 to 1.227 cc/sec for 22Fr, and - 0.055 to 1.243 cc/sec for 24Fr. In case of maximum bladder pressure with room temperature, the flow rates were - 0.180 to 0.868 cc/sec for 18Fr, - 0.212 to 1.028 cc/sec for 20Fr, - 0.220 to 1.072 cc/sec for 22Fr, and - 0.223 to 1.086 cc/sec for 24Fr. In case of minimum bladder pressure with cold fluid, the flow rates were - 0.028 to 0.365 cc/sec for 18Fr, - 0.033 to 0.749 cc/sec for 20Fr, - 0.034 to 0.781 cc/sec for 22Fr, and - 0.035 to 0.791 cc/sec for 24Fr. In case of maximum bladder pressure with cold fluid, the flow rates were - 0.112 to 0.553 cc/sec for 18Fr, - 0.131 to 0.653 cc/sec for 20Fr, - 0.137 to 0.681 cc/sec for 22Fr, and - 0.139 to 0.689 cc/sec for 24Fr. This study is significant in that it utilized a fluid dynamics approach to provide basic data for continuous bladder wash care. Through the findings of this study, nurses can plan the exchange time of irrigation fluid and the pattern of urinary drainage when performing continuous bladder irrigation. It is also inferred that there may be an advantage in not having to calculate additional material costs for using an infusion pump for patients by determining the hourly injection rate of irrigation fluid based on the height of the infusion set's drop chamber.
