Ultrasound-guided erector spinae plane block in coronary artery bypass surgery: the role of local anesthetic volume-a prospective, randomized study.
Trial report in General thoracic and cardiovascular surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundErector spinae plane block has been shown to help with pain management in different regions and many areas with different indications. However, the effectiveness of this block in cardiac surgery has been shown in the literature, the optimal volume remains unclear. The aim of this study is to determine the analgesic efficacy of two different volumes of local anesthetic injection used in ultrasound-guided bilateral-thoracic erector spinae plane block in patients undergoing coronary artery bypass graft.
methodsThis study was conducted on adult patients undergoing surgery with coronary artery bypass graft, and 70 patients were analyzed in each group. Group 20 received erector spinae plane block with 20 ml of 0.25% bupivacaine, Group 30 received 30 ml of 0.25% bupivacaine bilaterally. Postoperative sternotomy and chest tube-related pain were evaluated using the numerical rating scale (NRS) at rest and during movement.
resultsThere were significant differences between the groups regarding rescue tramadol consumption was higher in Group 20 than in Group 30 (25/35 vs. 2/35, p < 0.001). In addition, there were substantial differences between the two groups concerning the time of the first-rescue analgesic requirement. The mean time ± standard deviation was 11.26 ± 9.57 h and 24.03 ± 4.12 h in Groups 20 and 30 (p < 0.001). The median scores, both at sternotomy and chest tubes, were significantly lower in Group 30 than in Group 20 at the different time points after the surgery (p < 0.05).
conclusionsIn coronary artery bypass graft surgery, erector spinae plane block performed with 30 ml instead of 20 ml on each side resulted in less pain in the sternum and chest tube region, less need for rescue analgesics, and delayed first-rescue analgesic requirement.
