1 · What the graph read from it

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.

Abstract

introductionPostoperative nausea and vomiting (PONV) is one of the most common postoperative complications, with particularly high rates in patients undergoing high-risk surgeries such as gynecologic laparoscopy. Although there are many pharmacological and non-pharmacological methods that can prevent PONV, the incidence remains high. This study assessed the effectiveness of a right stellate ganglion block (SGB) in preventing PONV in gynecological laparoscopy patients, while also exploring the potential mechanisms involved.

methodsTwo hundred patients were randomly assigned to either a right SGB under ultrasound guidance 30 min before anesthesia (SGB group) or no treatment (control group). The primary outcome was PONV incidence within 24 h post surgery. Secondary outcomes included nausea and vomiting severity, pain scores, postoperative flatus time, sleep quality, and satisfaction scores.

resultsThe incidence of PONV in the SGB group was 38%, significantly lower than the 60% in the control group (P = 0.002). Severity of PONV was also notably reduced in the SGB group (P = 0.004). Resting pain scores in the SGB group at 6 h (0.0 [0.0, 1.0] vs. 0.0 [0.0, 2.0], P = 0.013), 12 h (0.0 [0.0, 1.0] vs. 0.0 [0.0, 2.0], P = 0.027), and 24 h (0.0 [0.0, 1.0] vs. 0.0 [0.0, 2.0], P = 0.011) were lower than in the control group. Post-activity pain scores at 6 h (2.0 [1.0, 3.0] vs. 3.0 [1.25, 4.0], P = 0.000), 12 h (2.0 [1.0, 3.0] vs. 3.0 [1.25, 4.0], P = 0.002), and 24 h (2.0 [1.0, 3.0] vs. 3.0 [2.0, 4.0], P = 0.001) were also lower. The time to first postoperative flatus was shorter in the SGB group (P = 0.033). Overall postoperative satisfaction (P = 0.002) and analgesia satisfaction (P = 0.002) were higher, and sleep quality was improved (P = 0.046).

conclusionA right stellate ganglion block reduces PONV, pain, and postoperative flatus time, and improves sleep quality and satisfaction in gynecological laparoscopy patients, proving it to be a safe and effective method.
