Blood Conservation Protocol for Patients Undergoing Left Ventricular Assisted Device Implantation.
Article in Annals of cardiac anaesthesia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesThis study aims to compare intraoperative blood transfusion and perioperative outcomes for patients undergoing left ventricular assist device (LVAD) implantation before and after the implementation of a blood conservation protocol.
methodsThis retrospective cohort study included patients who underwent LVAD implantation from June 2017 to October 2024 at our Hospital. The primary outcome was total intraoperative transfusion volume, and secondary outcomes included intraoperative transfusion volume and rates of red blood cells (RBC), fresh frozen plasma (FFP), platelets, and reoperation due to bleeding. Exploratory outcomes included mortality and serious complications before hospital discharge.
resultsIn total, 120 patients were included, with 62 receiving traditional care and 58 treated with blood conservation protocol. After protocol implementation, total intraoperative transfusion volume decreased from 3.23 ± 3.24 units to 1.74 ± 1.56 units (P = 0.002). The intraoperative RBC transfusion rate dropped from 30.6% to 8.6% (P = 0.003), and the transfusion volume fell from 1.00 ± 1.71 units to 0.31 ± 1.05 units (P = 0.009). In multivariate analysis, the protocol was significantly associated with reduced total intraoperative transfusion volume, lower RBC transfusion volume and rate, and shorter ICU and hospital stays, while not correlated with perioperative mortality or serious complications.
conclusionsThe blood conservation protocol significantly reduced intraoperative transfusion in LVAD patients and expedited recovery.
