Analgesic Efficacy of Ultrasound-Guided Erector Spinae Plane Block in Patients with Extrahepatic Portal Venous Obstruction Undergoing Splenectomy: A Randomized Controlled Trial.

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
backgroundPostoperative pain is quite prevalent in patients undergoing splenectomy and shunt surgery for extrahepatic portal venous obstruction (EHPVO) via midline laparotomy incision. Most of these patients present with thrombocytopenia in the preoperative period. The presence of thrombocytopenia excludes the placement of epidural catheter for postoperative analgesia, which is considered the gold standard for laparotomies. Systemic opioids remain the cornerstone of pain management in such cases, but they have their side effects. Better alternatives need to be explored to improve postoperative pain management and recovery. The erector spinae plane block (ESPB) has an excellent risk-benefit ratio and has been used for a wide range of cases, from acute postoperative pain to chronic pain conditions. METHODOLOGY: This was a randomized controlled trial conducted on 84 patients who underwent splenectomy with lienorenal shunt surgery under general anesthesia. Patients in the study group were given ESPB before extubation, while the control group was managed on conventional analgesics. The primary objective was postoperative opioid requirement by intravenous patient-controlled analgesia (PCA) in both groups. Secondary objectives were static and dynamic Numerical Rating Scale (NRS) scores, hospital stay duration, time first to rescue analgesia, and incidences of adverse events.
resultsPatients in the ESPB group had less requirement of fentanyl in the postoperative period (median of 100 µg as compared to 880 µg in control group in first 24 hours). Static and dynamic pain scores were also less in the ESPB group at all time points (
conclusionsUltrasound-guided ESPB provides superior analgesia and recovery with fewer side effects than conventional analgesics.
