Ultrasound-Guided Suprainguinal Versus Infrainguinal Fascia Iliaca Compartment Block for Postoperative Analgesia After Total Knee Replacement: A Prospective Randomized Trial.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
backgroundFascia iliaca compartment block (FICB) can be achieved using suprainguinal (SFICB) or infrainguinal (IFICB) approaches. This study compares postoperative analgesia of SFICB and IFICB after total knee replacement (TKR).
methodsThis prospective, randomized, single-blind study was conducted on 60 adult patients undergoing unilateral TKR under spinal anesthesia. Patients were randomly allocated into two groups: Group S received SFICB with 30 mL of 0.25% levobupivacaine with 2 mL (8 mg) dexamethasone, while Group I received IFICB with the same drugs after surgery. The primary outcome variable was 24-hour cumulative tramadol consumption. Secondary outcome variables included pain intensity, complications, hemodynamic variations, and time to first rescue analgesic request.
resultsTramadol consumption was significantly lower with SFICB (86.67±34.57 versus 34.57±33.95 mg, p=0.006). Pain intensity was lower with SFICB after six hours of surgery. Time to first analgesic request was also longer with SFICB (12.83±3.80 versus 10.12±2.98 hours, p=0.003). Time taken for administering the blocks (16.20±2.66 versus 17.17±3.13 minutes), complications, and hemodynamic variations were statistically similar between the groups.
conclusionSFICB provides superior postoperative analgesia compared to IFICB in patients undergoing TKR, with reduced opioid requirement and prolonged analgesia duration.
