Efficacy of Intrathoracic Intercostal Nerve Block on Postoperative Acute and Chronic Pains of Patients Undergoing Video-Assisted Thoracoscopic Surgery.
Trial report in Journal of pain research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Background: Patients undergoing video-assisted thoracoscopic surgery (VATS) frequently suffered postoperative acute and chronic pains. In recent years, intrathoracic intercostal nerve block (INB) is regularly used thanks to its safety and accuracy, especially under the circumstance of lacking ultrasound or in face of the contraindications of the thoracic paravertebral block (TPVB). However, clinical evidence of comparing TPVB and INB for pain management after VATS has been limited and the observation of the chronic pain has been less than clear. Methods: A total of 180 patients undergoing VATS were randomly divided into three groups: A single multi-point paravertebral nerve block (Group P), intrathoracic intercostal nerve block (Group I), and general anesthesia without any regional block (Group C). Postoperative acute pain was scored at rest and coughing by the Visual Analog Scale (VAS) for recording 24h, 48h and 72h after VATS. All patients were interviewed 1, 3 and 6 months after the surgery to investigate both the incidence and intensity of chronic pains. Results: There were significantly less incidence and intensity of acute pain in Group P and Group I, compared to those in Group C. The patients in Group I showed the least incidence and intensity of chronic pain after 3 months compared with those in Group P and Group C. There are 89 of 98 patients suffering pains after 1 month, which grew into chronic pains after 3 months and 78 of them still suffered chronic pains even after 6 months. Conclusion: The intrathoracic INB offers excellent relief from acute and chronic pains, which does as effectively as TPVB. Besides, one-month postoperative pain could increase the risk of a chronic one.
