Effect of adding dexmedetomidine as an adjuvant to bupivacaine in ultrasound-guided erector spinae plane block for postoperative pain management following modified radical mastectomy: a randomized controlled trial.
Trial report in BMC surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06022614 (Effect of Adding Dexmedetomidine As Adjuvant to Bupivacaine in Ultrasound Guided Erector Spinae Plane Block for Post Modified Radical Mastectomy Pain Management), which is not on this 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.

Abstract
backgroundPostoperative pain after modified radical mastectomy (MRM) can lead to significant morbidity. The erector spinae plane block (ESPB) has emerged as an effective regional anesthesia technique. This study evaluated the effect of adding dexmedetomidine to bupivacaine on postoperative analgesia following ESPB in MRM. PATIENTS AND
methodsThis double-blinded, randomized controlled trial included 60 female patients (ASA I–II, age 30–65 years, BMI < 35 kg/m²) undergoing MRM at Ain Shams University Hospitals between August 2023 and July 2024. Patients were randomly allocated into two groups (n = 30 each): Group B received unilateral ESPB with 20 ml of 0.5% bupivacaine, and Group BD received 10 ml of 0.5% bupivacaine plus dexmedetomidine (100 µg/mL, 1 µg/kg) diluted to a total volume of 20 ml with 0.9% saline. Blocks were performed postoperatively in lateral decubitus position under ultrasound guidance. Rescue analgesia consisted of IV nalbuphine 5 mg for VAS > 4.
resultsThe median (IQR) time for request of the initial dose rescue analgesia was significantly delayed in group BD compared to group B [690 (525–795) versus 360 (300–420), respectively, P-value < 0.001]. The number of patients that required nalbuphine was significantly lower in group BD compared to group B (P-value = 0.004). The median (IQR) visual analogue scale (VAS) scores at 6 h postoperative were significantly reduced in group BD compared to group B [1 (1–2) versus 4 (4–4), P-value < 0.001].
conclusionOur study’s results indicated that adding dexmedetomidine to bupivacaine in ESPB enhanced its efficacy, extended postoperative pain relief, and reduced the need for nalbuphine. CLINICAL
