Hypertonic saline achieves superior brain relaxation in tumor craniotomy: An updated systematic-network meta-analysis.
Review in Journal of Taibah University Medical Sciences, 2024. 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
Background: Brain tumor craniotomy requires relaxation of the brain through decreasing the intracranial pressure (ICP). Osmo-hyperosmolar therapy can be used to lower the ICP. Objectives: This study was aimed at updating previous studies to determine the effects and safety of using hypertonic saline (HTS) and mannitol to decrease ICP in adult patients with brain tumors undergoing craniotomy. Methods: To identify randomized controlled trials (RCTs) comparing HTS vs mannitol, we performed a systematic literature search according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, by examining records from 2013 to December of 2023 in five databases. The primary outcome was brain relaxation, and the secondary outcomes were cerebral perfusion pressure (CPP), urine output (UO), fluid input, mean arterial pressure (MAP), and plasma sodium. Conventional meta-analysis, Bayesian meta-insight analysis, trial-sequential analysis, and trial quality assessment were conducted. Results: Eleven RCTs involving 593 participants were included in the meta-analysis. Use of HTS, compared with mannitol, was associated with significantly greater brain relaxation, and significantly lower UO and fluid input. HTS was also significantly associated with elevated MAP. Plasma sodium was significantly higher in the HTS group than the mannitol group. No significant difference in CPP was observed between groups. Trial sequential analysis indicated true significance for the brain relaxation outcomes. Bayesian analysis demonstrated the superiority of 3% HTS at 5 ml/kg in achieving brain relaxation, followed by 3% HTS at 5.3 ml/kg and 20% mannitol at 5 ml/kg. Conclusions: HTS is superior to mannitol in achieving optimal brain relaxation, maintaining stable blood flow, and minimizing diuretic effects. However, use of HTS during tumor craniotomy procedures can increase plasma sodium levels. The optimal dose for achieving brain relaxation appears to be 3% HTS at 5 ml/kg body weight.
