Enhanced sedative efficacy and delayed recovery in propofol anesthesia in a rat model of hepatic cirrhosis.
Article in International journal of clinical and experimental medicine, 2015. 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
purposeThe sedative efficacy of propofol anesthesia is enhanced in patients with hepatic cirrhosis. Establish a rat model to investigate the efficacy of propofol.
methods100 healthy Sprague-Dawley rats were divided into three groups and administered Phenobarbital sodium, carbon tetrachloride and ethanol solution for 0 (control), 9 (mild cirrhosis, M1), or 12 (severe cirrhosis, M2) weeks to induce hepatic cirrhosis. Propofol was infused via the caudal vein and the ED50 of the sedative effect and the recovery time were assessed according to the loss and recovery of the righting reflex. The effect of propofol on circulating cells and platelets, blood biochemistry and neurotransmitter content of the brain were measured.
resultsCirrhosis was achieved in 25 of 35 M1 and 27 of 45 M2 rats. The propofol ED50 was significantly lower in M1 and M2 (5.8 ± 1.2 and 4.8 ± 1.1 mg/kg, respectively) than in control rats (6.2 ± 1.1 mg/kg, P < 0.05), and the time to recovery of righting reflex was significantly longer in M1 and M2 (370.0 ± 108.2 s and 501.6 ± 100.1 s, respectively) than in control rats (275.0 ± 90.3 s, P < 0.05). In M1 and M2 rats white and red blood cell and platelet counts were reduced, but ALT and AST activity was increased. In M1 and M2 rats the cerebral content of Gly and GABA increased but Glu and Asp were reduced.
conclusionThe sedative efficacy of propofol anesthesia is enhanced in rats with hepatic cirrhosis, perhaps due to reduced hepatic functional reserve, enhancement of inhibitory neurotransmitters and reduction of excitatory neurotransmitters.
