Awake Versus Asleep Intubation for Mediastinal Goiters: A Systematic Review and Meta-Analysis.

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
ImportanceMediastinal goiters can complicate anesthetic management, and although awake bronchoscopic intubation is the gold standard, it is resource-intensive and may be unpleasant for patients. In many centers across North America, patients undergoing thyroidectomy for mediastinal goiters are routinely intubated awake.ObjectiveThis study aimed to evaluate the outcomes of intubation in patients selected for awake versus asleep intubation for thyroidectomy of mediastinal goiters.DesignPRISMA 2020 Checklist for systematic reviews was followed. A search was performed in the Medline, Embase, Web of Science, CINAHL, Scopus, and Cochrane databases. Two independent reviewers performed abstract and full-text review. Data were extracted in duplicate. Study quality was assessed using the JBI Critical Appraisal tool. To account for heterogeneity, a 3-level random-effects model was constructed using the Der Simonian and Laird method with an arcsine transformation.Setting and ParticipantsPatients undergoing thyroidectomy for benign mediastinal goiters.Intervention and ExposuresAwake or asleep intubation.Main Outcome(s) and Measure(s)Rate of failed intubations in asleep intubation and proportion of uncomplicated intubations in asleep and awake populations.ResultsTwelve of 490 identified studies, involving 1002 patients, were included. Three cases of failed intubations were found in the asleep intubation group, with an overall incidence of failed intubation of 0.3%. Meta-analysis demonstrated an overall uncomplicated intubation rate of 91% (95% CI 77%-98%, n = 1002). Subgroup analyses showed a 96% success rate (95% CI 73%-100%, n = 60) for awake intubations and 88% (95% CI 69%-98%, n = 942) for asleep intubations. Further refined analyses showed uncomplicated intubation rates of 98% (95% CI 93%-100%, n = 469) for asleep, and 92% (95% CI 78%-99%, n = 48) for awake groups.Conclusions and RelevanceThe risk of failed intubation in patients with mediastinal goiters remains low, and awake intubation may require more attempts than asleep intubation. Further research with standardized definitions of intubation difficulty is needed.
