A Comparison of the Effect of Isoflurane and Propofol on Liver Enzymes.

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
Background: Isoflurane and propofol are routinely used for the maintenance of general anaesthesia. However, recently, they have been implicated in hepatotoxicity resulting in acute liver failure. Objective: We compared the effects of isoflurane and propofol on liver enzymes; aspartate transaminases (AST), alanine transaminases (ALT), alkaline phosphatase (ALP) and total bilirubin (Tbil) following general anaesthesia. Materials and Methods: This randomized, controlled clinical trial involved 60 ASA I and II patients aged 18-64 years scheduled for elective surgery requiring general anaesthesia. Anaesthesia was induced with intravenous sodium thiopentone 5 mg/kg and atracurium 0.5 mg/kg, and maintained in group I with isoflurane (MAC, 0.8%-1.5%) and in group P with (propofol infusion, 100-200µg/kg/minute). Blood samples were taken pre-induction, immediate- and 24 hours post operatively. The serum levels of AST, ALT, ALP, Tbil were analyzed and compared in both groups. Risk factors for post operative hepatotoxicity were determined. Result: Propofol caused a significant reduction in ALP ( Conclusion: Both agents had a varied effect on liver enzymes. Isoflurane resulted in a significantly higher increase in 24 hours post-operative serum AST than propofol. Propofol caused a significant increase in 24 hours post-operative total bilirubin. Caution is therefore recommended in their use in patients with altered liver enzymes.
