Surgeon-administered regional nerve blocks during radical cystectomy: a feasibility 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
objectiveTo describe the technique for surgeon-administered, ultrasound-guided transversus abdominis plane (SU-TAP) blocks performed during radical cystectomy as a component of multimodal, perioperative pain management.
methodsRetrospective, case series of patients receiving SU-TAP blocks just prior to incision for RC. TAP blocks were performed by the surgeon with a standard technique using US guidance to instill an anesthetic solution. The primary outcome was opioid consumption at the intervals of 0-12, 12-24, 24-36, and 36-48 h postoperatively. Opioid consumption was reported as oral morphine milligram equivalents (MME). Secondary outcomes included time to perform SU-TAP blocks, and safety of block procedure.
results34 patients were included. During the median length of stay of 4 days (interquartile range [IQR] 3-7), only 30/34 (88%) of patients required opioids within the first 12 h post-op, decreasing to 38% by 48 h post-op. The median consumption decreased in the first 48 h from 21 MMEs (IQR 9-38) to 10 MMEs (IQR 8-15) at the 0-12 and 36-48 h intervals, respectively. The median time to perform block procedure was 6 min (IQR 4-8 min) and there were no safety events related to the SU-TAP blocks. Limitations include no comparative arm for opioid consumption.
conclusionOur data suggest that urologists may feasibly perform US-guided TAP blocks as a practical, efficient, and safe method of regional anesthesia. SU-TAP blocks should be considered in ERAS protocols for RC. Future comparative studies on opioid consumption compared to local infiltration and alternative block techniques are warranted.
