Transversus Abdominis Plane Block With Dexamethasone and Dexmedetomidine Decreases Opioid Consumption, Length of Stay, and Ileus After Laparoscopic Colorectal Resection.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThis study investigated the impact of transversus abdominis plane (TAP) blocks containing bupivacaine hydrochloride, dexamethasone, and dexmedetomidine on postoperative outcomes following laparoscopic colorectal resections. PATIENTS AND
methodsThis retrospective cohort study included patients who had undergone elective laparoscopic colorectal resections between 2019 and 2022. Patients received either local wound infiltration or TAP blocks. TAP blocks were comprised of bupivacaine hydrochloride, dexamethasone, and dexmedetomidine. Local infiltration was with bupivacaine alone. Postoperative morphine milligram equivalents (MME) and visual analog scale (VAS) scores were compared. Predictors of MME and length of stay (LOS) were investigated by multiple linear regression.
resultsA total of 195 patients met the inclusion criteria. Among them, 90 (46.1%) received local wound infiltration, while 105 (53.9%) received TAP blocks. Patients in the TAP block group experienced lower postoperative MME at 24 hours (49.9 mg vs. 77.33 mg, p = 0.028) and a shorter LOS of 4.4 ± 2.2 days compared to 6.1 ± 5.1 days (p = 0.001). VAS scores showed statistically similar results between treatment groups at all three postoperative time points. Additionally, TAP blocks were associated with a reduced incidence of postoperative ileus (0% vs. 5%, p = 0.01). Multiple linear regression indicated that TAP blocks were independently associated with lower MME at 24 hours after surgery (β = -31.3, 95% CI: -57.5 to -5.1, p = 0.019) and a shorter LOS (β = -1.9, 95% CI: -3.4 to -0.4, p = 0.013).
conclusionTAP blocks using bupivacaine, dexamethasone, and dexmedetomidine are associated with decreased opioid consumption at 24 hours, shorter LOS, and reduced ileus compared to local infiltration alone.
