Clinical outcomes of ketamine in patients with traumatic brain injury: A systematic review.
Review in International journal of critical illness and injury science. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The current literature provides contradictory results concerning the impact of ketamine-induced anesthesia on traumatic brain injury (TBI) outcomes. This study aimed to investigate the potential of ketamine boluses to influence the brain pathophysiology in TBI patients. Twenty-one studies (n = 886) were extracted from PubMed, Web of Science, Scopus, CINAHL, and Cochrane Library. The primary endpoints included intracranial pressure (ICP) and cerebral perfusion pressure (CPP). The secondary endpoints were mean arterial pressure (MAP), heart rate (HR), electroencephalography (EEG), mean cerebral blood flow velocity, jugular oxygen saturation, ventilation, neurological outcomes, mortality, and overall efficacy and side-effects of ketamine-induced anesthesia. Four studies indicated a statistically significant decline in ICP in TBI patients, with ketamine sedation. Contrastingly, two studies revealed statistically significant ICP elevations, after ketamine-induced anesthesia, in TBI patients. Five studies negated any correlation between ketamine dosages and ICP changes. Three studies indicated a statistically significant increase in CPP after ketamine-induced anesthesia in TBI patients. One study revealed CPP decline after the administration of ketamine-midazolam treatment to TBI patients. Five studies revealed no noticeable influence of ketamine bolus on CPP in TBI patients. Similarly, inconsistent variations were observed in most of the secondary endpoints, including electroencephalography, neurologic outcomes, and ketamine-related side effects (all P <0.05). This systematic review emphasizes the role of ketamine-induced anesthesia in inconsistently improving or deteriorating clinical outcomes in patients with TBI. Future studies should evaluate the predominant causes (i.e., factors and attributes) of ketamine-related clinical outcomes in the TBI setting.
