Effect of ultrasound-guided bilateral rectus sheath block on postoperative pain control after robotic single-site gynecologic surgery: a randomized controlled study.

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
purposeRectus sheath block (RSB) is a simple abdominal wall block that can be readily applied. This study evaluated the postoperative analgesic efficacy of ultrasound-guided bilateral RSB in robotic single-site gynecologic surgery.
methodsSixty patients were randomly assigned to the RSB group (n=30) or the control group (n=30). After induction of general anesthesia, patients in the RSB group received ultrasound-guided bilateral RSB with 30 mL of 0.25% ropivacaine. Pain intensity was assessed using a verbal numerical rating scale (VNRS) at 0, 1, 6, 12, 24, and 48 hours postoperatively. Intravenous patient-controlled analgesia was provided to all patients, and fentanyl was administered as rescue analgesia on request.
resultsVNRS scores at 0, 1, and 6 hours were significantly lower in the RSB group than in the control group (all P<0.05). Rescue fentanyl use in the post-anesthesia care unit was also significantly lower in the RSB group than in the control group (19.8±21.0 μg vs. 46.3±27.6 μg, P<0.001). Subgroup analysis showed that RSB was associated with lower VNRS scores in patients undergoing ovarian surgery or myomectomy, whereas no significant difference was observed in patients undergoing hysterectomy.
conclusionUltrasound-guided bilateral RSB reduced early postoperative pain and rescue analgesic requirements after robotic single-site gynecologic surgery.
