Opioid sparing anesthesia in patients with liver cirrhosis undergoing liver resection: a controlled randomized double-blind study.
Trial report in BMC anesthesiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveOpioid metabolism and pharmacodynamics may be affected in hepatic patients. Ketamine and dexmedetomidine are conventional anesthetics used in our daily practice. The opioid-sparing effects of this combination have not been evaluated in patients with liver cirrhosis undergoing liver resection. We aimed to investigate the potential peri-operative opioid-sparing effects of intra-operative dexmedetomidine and ketamine infusions in patients with Child A liver cirrhosis undergoing liver resection.
methodsThis study was a randomized controlled double-blind trial. 92 adult patients of both sex with Child class (A) liver cirrhosis aged 18 to 65 years entering and completing the study. We excluded patients with renal or cardiac dysfunction or contraindications from study medications.46 patients in the opioid-sparing group (OS) receiving ketamine and dexmedetomidine infusions and 46 patients in the opioid-based (OB) group as controls. The main outcome measures: were intra-operative fentanyl requirements, postoperative fentanyl requirements, visual analogue pain scores, postoperative nausea, vomiting, ileus, desaturation, intra-operative hemodynamic events, and ICU stay were recorded.
resultsThe total intra-operative fentanyl consumption was significantly lower in the OS group compared with the OB group, 183.2 ± 35.61 µg and 313.5 ± 75.06 µg, respectively, P < 0.001. The postoperative 1st 48 h fentanyl consumption was significantly lower in the OS group compared with the OB group, 354.5 ± 112.62 µg and 779.1 ± 294.97 ± µg, respectively, P < 0.001. Visual analogue scores were significantly better in the OS group at the early 2-hour assessment point postoperatively. The postoperative adverse events were significantly more frequent in the opioid-based group. ICU stay was significantly shorter in the OS group.
conclusionsAdministering dexmedetomidine and ketamine infusions intra-operatively to patients with Child A liver cirrhosis undergoing liver resection resulted in notable opioid-sparing effects, with reductions of approximately 40% intra-operatively and 55% postoperatively. The opioid-sparing group exhibited improved postoperative outcomes, including reduced pain, decreased incidence of opioid-related side effects and shorter ICU stays.
