Effect of controlled hypotension on postoperative awakening quality in shoulder arthroscopy with lateral decubitus rotator cuff repair.
Trial report in BMC anesthesiology, 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
backgroundBackground: Shoulder arthroscopy is commonly performed to treat shoulder injuries, degenerative conditions, and chronic pain. The quality of postoperative emergence is critical to patient recovery and overall surgical outcomes. However, few studies have investigated whether controlled hypotension affects emergence quality during shoulder arthroscopy. Controlled hypotension can optimize the surgical field, reduce operative time, decrease the risk of intraoperative complications, and enhance the quality of postoperative recovery. These benefits highlight its clinical utility and support its broader adoption in routine practice.
methodsA total of 120 patients (aged 18-60 years) scheduled for elective shoulder arthroscopy under general anaesthesia combined with brachial plexus nerve block were enrolled and randomly assigned to either the study group or the control group (n = 60 per group). In the study group, controlled hypotension was applied selectively during two key intraoperative phases: anchor stapling (T1) and suture knotting (T2). In contrast, the control group received continuous controlled hypotension throughout the entire procedure, targeting a 20% reduction in mean arterial pressure (MAP) from baseline upon entry into the operating room. Perioperative vital signs, quality of emergence from anaesthesia, and postoperative complications were recorded and analyzed.
resultThe study group exhibited significantly shorter awakening and extubation times compared to the control group (both P < 0.001). Additionally, the incidences of postoperative nausea and vomiting (11.7% vs. 26.7%), shivering (20.0% vs. 45.0%), and agitation (5.0% vs. 16.7%) were significantly lower in the study group than in the control group (P = 0.037, P = 0.003, and P = 0.037, respectively). Multivariable analysis demonstrated that the study group had significantly shorter awakening time (P < 0.001) and extubation time (P < 0.001), as well as a significantly lower incidence of postoperative nausea and vomiting (P = 0.045), independent of confounding factors including temperature, drug dosage, and urine output.
conclusionCompared to patients who underwent continuous controlled hypotension throughout rotator cuff repair, those who received controlled hypotension only during critical surgical steps-specifically stapling (Fig. 1) and suture knotting (Fig. 2)-experienced higher-quality postoperative awakening and fewer complications.
