Cardiac arrest during peri-anesthetic systemic induction and maintenance in valvular heart disease: proceed or abandon? Clinical validation of a modified cardiopulmonary bypass strategy in 21 patients.
Article in European journal of medical research, 2025. 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
backgroundCritical gaps persist in clinical guidelines and resuscitation strategies for induction and maintenance phase peri-anesthetic cardiac arrest (IM-PACA), urgently necessitating exploration of feasible solutions during anesthesia induction and maintenance periods. This study evaluates a modified cardiopulmonary bypass (CPB) strategy for managing IM-PACA in valvular heart disease (VHD) surgical patients.
methodsA retrospective analysis was performed on IM-PACA patients (n = 21) from 1,043 cardiac valve surgeries between March 2019 and January 2022 as the cardiac arrest-resuscitation group (CAR group). Patients who completed normal cardiac valve surgery (n = 84) were randomly selected from the medical record database as the Routine Surgery group (RS group), serving as a benchmark control for the standard efficacy of routine surgery. The CAR group completed surgery after modified cardiopulmonary bypass strategy; the RS group completed surgery as planned. This study reviewed the possible causes of cardiac arrest in the CAR group and performed statistical analysis on surgical time-related metrics (total surgical duration, cardiopulmonary bypass duration, etc.) and postoperative follow-up data (paravalvular leak, cardiac-related complications, etc.) using SPSS 26.0.
resultsThe short-term postoperative survival rate was 95.24% in the CAR group and 100% in the RS group. Baseline characteristics including gender, age, and smoking history showed no significant differences between the two groups (P > 0.05). The CAR group showed a significantly shorter pericardiotomy-to-CPB time (250.00 (205.00-269.50) vs. 512.50 (459.25-563.00) s; P < 0.001), but longer rewarming time (68.00 (63.50-74.50) vs. 48.00 (35.25-61.75) min; P < 0.001), ventilator duration (980.00 (619.00-1106.50) vs. 900.00 (630.00-1103.75) min; P = 0.002), and higher day 2 drainage (190 (157.50-215.00) vs. 105 (71.25-150.00) ml; P < 0.001) compared to the RS group. Other intraoperative and postoperative parameters revealed no statistically significant differences when compared with the RS group (P > 0.05).
conclusionsFor IM-PACA patients undergoing cardiac valve surgery, the modified cardiopulmonary bypass strategy is an effective rescue method, and the strategy of continuing surgery after resuscitation is completely feasible.
