Safety and Efficacy of Ultrasound-Guided Retrolaminar Block of Multiple Injections in Retroperitoneal Laparoscopic Nephrectomy: A Prospective Randomized Controlled Study.
Article in Journal of pain research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 11 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.

Abstract
purposeUltrasound-guided retrolaminar block (RLB) has the potential to provide postoperative analgesia in retroperitoneal laparoscopic surgery. This study was conducted to evaluate the effects of RLB when compared with local infiltration analgesia (LIA) in retroperitoneal laparoscopic nephrectomy. PATIENTS AND
methodsOne hundred and fifteen patients scheduled for laparoscopic nephrectomy were divided into two groups: the RLB group (n = 57) received an ultrasound-guided RLB, while the LIA group (n = 58) received LIA. At 2, 4, 6, 24, and 48 hours after operation, the maximal visual analog score (VAS), sufentanil and rescue analgesia consumption, and the utilization of patient-controlled intravenous analgesia (PCIA) were assessed. The incidence rates of postoperative nausea and vomiting (PONV); time of leaving bed (at the first instance); and the levels of plasma β-Endorphin (β-EP), Interleukin-1β (IL-1β), and prostaglandin E2 (PEG2) 30 min after extubation were noted.
resultsPatients in the RLB group had significantly lower VAS scores; lower sufentanil cumulative consumption; lower manual addition frequency of PCIA; lower proportion of using rescue analgesia within 48 hours after operation; lower incidence rate of PONV; shorter resuscitation times; earlier time of leaving the bed; and lower β-EP, IL-1 β, and PEG2 levels.
conclusionUltrasound-guided RLB of multiple injections is both safe and controllable for postoperative analgesia after retroperitoneal laparoscopic nephrectomy. When compared with LIA, RLB has better and longer-lasting analgesic effect, lower incidence rates of PONV, and the potential to reduce the level of postoperative inflammatory factors.
