The effects of ultrasound-guided QLB and TAPB combined with opioid-free anesthesia (OFA) on clinical efficacy of the patients undergoing abdominal surgery.
Article in Heliyon, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06663345 (A Comparison of the Effects of TAP), which is not on this map. Cited by 3 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.

Abstract
Background: Although opioids provide effective analgesia for abdominal surgery, they also present serious unwanted side effects. Ultrasound-guild quadratus lumborum block (QLB) and transversus abdominis plane block (TAPB) have been proven to offer long-lasting and efficient analgesia during abdominal surgery. However, the clinical efficacy of ultrasound-guided QLB and TAPB combined with opioid-free anesthesia (OFA) in abdominal surgery remains unclear. Objective: This study aimed to investigate the impact of ultrasound-guided QLB and TAPB combined with opioid-free anesthesia (OFA) on the clinical efficacy of abdominal surgery. Methods: A total of 122 patients scheduled for abdominal surgery at People's Hospital of Wanning between March 2021 and April 2022 were enrolled in this study. Participants were randomly divided into two groups: the experimental group (QLB/TAPB + OFA, 62 patients) and the control group (opioid anesthesia, 60 patients). The clinical efficacy of the QLB/TAPB combined with OFA technique was evaluated by analyzing patients' vital signs, postoperative consciousness recovery time, numeric rating scale (NRS) score, and immune function in both groups. Results: We observed that systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) in experimental group were significantly higher than those in control group after induction ( Conclusions: Ultrasound-guided QLB and TAPB combined with OFA technique can reduce pain intensity and enhance the patients' immune function in abdominal surgery.
