Comparison of effectiveness of the piston-pump method versus the pressure-infusor method for rapid infusion of crystalloids: A bench 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
aimsThe piston-pump method is a simple method for rapid administration of fluids but some problems are unsolved. We compared the effectiveness of using the piston-pump method with that of the pressure-infusor method.
methodsTwelve anaesthetists were classified randomly into the piston-pump and pressure-infusor groups. They were asked to infuse 500 ml of saline three times successively through a 16-G intravenous cannula as rapidly as possible using a pump with a 50-ml syringe or a pressure-infusor at 300 mmHg. The time taken for infusion and the maximum or minimum pressure in the infusion circuit and substitute vessel were measured. Bacterial culture of the saline infused sterilely was performed to estimate bacterial contamination.
resultsThe pressure-infusor group led to faster infusion of 500 ml of saline (233 ± 19 s) than the piston-pump group (301 ± 48 s) (
conclusionIf fluids must be administered rapidly, the pressure-infusor method is more efficient than the piston-pump method because the latter is less effective in infusing fluids rapidly and associated with excessive positive and negative pressure in the infusion circuit.
