A study of the analgesic efficacy of rectus sheath block in single-port total laparoscopic hysterectomy: a randomized controlled 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 investigate the postoperative analgesic effects of rectus sheath block (RSB) in combination with patient-controlled analgesia (PCA) compared with PCA alone after single-port total laparoscopic hysterectomy (TLH).
methodsThis randomized, single-blind study enrolled female patients that underwent single-port TLH. The patients were randomized to receive either fentanyl PCA (PCA group) or RSB with the same PCA. The primary outcomes were fentanyl consumption at 8 h postoperatively and visual analogue scale (VAS) pain scores, which represented the severity of postoperative pain.
resultsA total of 36 patients were enrolled in the study: 18 in the PCA group and 18 in the RSB group (two patients were excluded). The primary outcome of fentanyl consumption was significantly lower at 8 h postoperatively in the RSB group than in the PCA group (148 ± 61 µg versus 222 ± 107 µg, respectively). VAS scores were significantly lower at arrival in the post-anaesthesia care unit and at 30 min after arrival in the RSB group compared with the PCA group. There were no significant differences in the nausea/vomiting score and in additional analgesic consumption between the two groups.
conclusionsRSB can be used as a multimodal approach for pain control in single-port TLH procedures.Clinical Research Information Service (no. KCT0001461).
