Preoperative echocardiography and anesthetic drugs as predictors of post-induction hypotension during general anesthesia: a prospective observational study.
Observational study in Scientific reports, 2024. 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
Post-induction hypotension (PIH) during general anesthesia is a serious concern due to its high incidence and association with adverse postoperative outcomes and prognosis. We prospectively enrolled consecutive 1,603 patients scheduled for non-cardiac and cardiac surgery under general anesthesia. The primary outcome was defined as the lowest mean blood pressure from induction of general anesthesia to the start of surgery: post-induction blood pressure (PIB). Multivariable regression analysis was used to investigate the relationships between PIB and preoperative echocardiographic measurements, types and doses of anesthetic agents, and preoperative comorbidities and oral medication. Left ventricle regional wall motion abnormality (RWMA) and lower estimated glomerular filtration rate significantly associated lower PIB. Factors significantly associated with higher PIB were high BMI, beta blockers, high pre-induction mean blood pressure, and starting induction in the afternoon. Sevoflurane and prophylactic norepinephrine use were associated with higher PIB as anesthetic interventions. Significant interactions were found between sevoflurane and RWMA (P for interaction: 0.01). This is the first study to demonstrate the feasibility of intervening in the selection of anesthetic agents based on echocardiographic findings and to recommend the use of sevoflurane and prophylactic norepinephrine for the prevention of PIH, especially in patients with RWMA.
