Effect of Local Anesthesia at the Bone Collection Site of Iliac Bone Grafting on Autonomic Nervous System Activity and Circulatory Dynamics in Alveolar Cleft Treatment.
Article in Pain research & management, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
backgroundIn alveolar bone graft surgery, local administration of ropivacaine at the iliac bone donor site is expected to have an analgesic effect. However, its effects on autonomic nervous system activity and circulatory dynamics are unknown.
aimsThis study aimed to assess the effects of local ropivacaine administration to the iliac region under general anesthesia by analyzing changes in autonomic nervous system activity and circulatory dynamics.
methodsWe retrospectively reviewed medical records of patients who underwent iliac bone grafting under general anesthesia between May 2021 and December 2022. At the end of surgery, ropivacaine was administered locally in the iliac region. Heart rate variability (HRV), heart rate (HR), and systolic blood pressure (SBP) were analyzed 5 min prior to (baseline) and 5 min following (postadministration) ropivacaine administration.
resultsSeventeen patients were included in the analysis. The low/high frequency ratio was significantly elevated after ropivacaine administration compared with baseline (p < 0.05). No significant changes were observed in high frequency, HR, or SBP (p < 0.05).
conclusionLocal administration of ropivacaine in the iliac region under general anesthesia resulted in detectable neurological changes, as evidenced by HRV analysis, though conventional circulatory parameters remained unchanged. HRV may provide sensitive detection of perioperative stress beyond what is captured by hemodynamic measures alone.
