Comparison between nurse anesthetists and anesthesiology residents of blood pressure management during general anesthesia: a retrospective analysis using an electronic anesthesia record database.
Article in BMC anesthesiology, 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
backgroundSeveral Japanese educational institutions have begun to train nurse anesthetists. They manage the patient consistently from pre-operation to post-operation in collaboration with the anesthesiologist. This has helped improve the quality of anesthetic management in an anesthesiologist shortage environment in Japan. However, no studies have examined the quality of anesthetic management by nurses worldwide. Therefore, this study investigated the quality of anesthesia among novice anesthesiology residents and nurse anesthetists, focusing on blood pressure control.
methodsThis study included adult patients undergoing breast surgery. Nurse anesthetists or anesthesiology residents oversaw general anesthesia. Intraoperative electronic medical records were used to compare the general anesthesia management of nurses and residents. The primary outcome was the sum of the duration during which the mean blood pressure was < 65 mmHg. This was quantified as a percentage of the total anesthesia time (time under mean 65 mmHg: TUm65). Independent variables included patient demographic characteristics, clinical information, the percentage decrease from baseline in the lowest mean blood pressure during anesthesia, and the hourly infusion volume.
resultsNo significant difference was observed in the TUm65 (nurse anesthetists vs. anesthesiology residents: median [IQR] 11.3% [3.3-20.7] vs. 18.1% [5.3-24.0], p = 0.078). No significant differences were noted between nurses and residents concerning the other outcomes.
conclusionNo significant differences were observed in the intraoperative blood pressure control between the nurse anesthetists and anesthesia residents.
