Anesthesiology Considerations and Management of Venous Air Embolism in Patients in the Semisitting Position: A Single-Center Review.
Article in Cureus, 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
backgroundThe semisitting position is often preferred for neurosurgical procedures requiring access to the cerebellopontine angle or posterior fossa. Despite benefits such as improved venous drainage and reduced intracranial pressure, its use has been controversial due to risks like venous air embolism. Recent advancements in intraoperative monitoring and management have caused renewed interest in this position. This study reviews our institution's experience, focusing on strategies to mitigate complications and improve outcomes in semisitting craniotomies. MATERIALS AND
methodsNinety-four consecutive adult patients who underwent intracranial neurosurgery in the semisitting position were enrolled in the study. The surgery and anesthesiology reports were reviewed to extract data regarding demographics, intraoperative monitoring, and postoperative complications. For each patient who experienced a venous air embolism, an additional set of hemodynamic data was collected. Data management and statistical analyses were performed using Statistical Analysis System (SAS) software (version 9.4, 2023, SAS Institute Inc., Cary, NC, USA).
resultsVenous air embolism occurred in a total of 21 patients (22.34%). Out of these 21 patients, one experienced a venous air embolism that coincided with a decrease in end-tidal carbon dioxide
conclusionThe semisitting position remains a valuable approach in neurosurgery. We identified multiple factors important in reducing the risk of complications and managing them when they occur. Robust anesthesia guidelines should be developed so that this modality can be used more broadly.
