Blood pressure management during cardiac surgery: a survey of Canadian cardiac anesthesiologists, perfusionists, and cardiac surgeons.
Article in Canadian journal of anaesthesia = Journal canadien d'anesthesie, 2025. 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
purposeClinicians presume a relationship between the management of blood pressure during cardiac surgery and postoperative morbidity and mortality. With limited evidence to inform practice, we surveyed Canadian cardiac anesthesiologists, perfusionists, and cardiac surgeons. We sought to solicit information to inform a trial evaluating the blood pressure management approach on outcomes after cardiac surgery.
methodsWe iteratively developed a survey assessing the lowest and highest blood pressures respondents would target, the narrowest feasible blood pressure range to achieve, the range of blood pressure observed in clinical practice, and factors influencing targeted blood pressure before, during, and after cardiopulmonary bypass (CPB). We contacted leads from every Canadian hospital providing cardiac surgery to distribute the survey via a computerized link. We used a modified Dillman approach to optimize response rate. Responses were analyzed descriptively.
resultsOf 819 clinicians surveyed, 532 (65%) responded. Respondents' lowest pooled mean arterial pressure (MAP) target, presented as mean (standard deviation [SD]), was 59 (6) mm Hg before CPB, 55 (7) mm Hg during CPB, and 60 (5) mm Hg after CPB. Respondents' highest pooled MAP target, presented as mean (SD), was 92 (10) mm Hg before CPB, 84 (7) mm Hg during CPB, and 75 (6) mm Hg after CPB. The narrowest feasible MAP range, presented as mean (SD), all respondents believed could be achieved was 19 (7) mm Hg before CPB, 16 (7) mm Hg during CPB, and 20 (7) mm Hg after CPB.
conclusionsThe responses to our survey support the clinical acceptability of a trial examining blood pressure target thresholds at the extreme ends of the range recommended by existing guidelines and the feasibility of maintaining blood pressure within a narrow target range.
