Effectiveness of intraoperative blood recovery in surgical patients at risk of transfusion: A rapid review.
Review in Hematology, transfusion and cell therapy, 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
backgroundAllogeneic blood transfusion is widely used to manage surgical blood loss but carries risks, such as infections and transfusion reactions, and is affected by blood shortages. Intraoperative blood recovery (cell salvage) may reduce the need for donor blood, improving patient safety and resource availability. This rapid review evaluated its clinical effectiveness, safety, and costs in surgical patients at risk of transfusion.
methodsFollowing the Cochrane rapid review guidelines, PubMed, the Virtual Health Library, and the Cochrane Library were searched for systematic reviews, randomized and non-randomized trials, and observational studies published between 2004 and October 2024. Eligible studies compared intraoperative blood recovery with allogeneic transfusion or no intervention in surgical patients. Outcomes included transfusion requirements, clinical safety, hospital indicators, and costs. Study quality was assessed using the AMSTAR-2 and Joanna Briggs Institute tools.
resultsFifty-two studies across multiple surgical specialties were included. Intraoperative blood recovery consistently reduced allogeneic transfusion requirements in orthopedic, obstetric, gastrointestinal, and pediatric cardiac surgeries. Evidence was mixed for cardiac, thoracic, and vascular surgeries. Safety profiles were favorable, with no significant adverse events directly attributed to intraoperative blood recovery. Some studies reported reductions in infection rates and hospital stay. Cost analyses (n = 16) yielded mixed results, with eight studies showing cost savings due to reduced transfusion needs.
conclusionIntraoperative blood recovery is effective and safe in reducing allogeneic transfusions, especially in high-blood-loss surgeries. Cost-effectiveness is context-dependent. Implementation should prioritize high-risk procedures and align with patient blood management strategies.
