Measures to prevent acute airway obstruction after anterior cervical spine surgery: a retrospective cohort study from Japan and a review of the literature.
Article in Asian spine journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
STUDY
designA retrospective cohort study and literature review. PURPOSE: We analyzed the clinical characteristics of acute airway obstruction (AAO) after anterior cervical spine surgery (ACSS), evaluated the effectiveness of newly implemented preventive measures, and assessed whether extubation immediately after surgery is practical. OVERVIEW OF LITERATURE: AAO is a rare but potentially fatal complication after ACSS. Recent studies have focused on postoperative management strategies such as prolonged intubation in the intensive care unit; however, the feasibility and safety of immediate extubation have not been studied extensively. This study addressed this critical gap.
methodsWe retrospectively reviewed data from patients who underwent ACSS and then immediate extubation according to policy at our institution between April 2006 and January 2019. Patients were categorized into AAO and non-AAO groups according to whether postoperative airway compromise necessitated reintubation or hematoma evacuation. Statistical analyses identified surgery-related risk factors associated with AAO. These findings and a review of the literature prompted the implementation of 10 preventive measures in February 2019. We then analyzed outcomes from 156 subsequent cases of ACSS.
resultsAAO occurred in 7 (0.68%) of 1,036 patients. Significant risk factors included the number of fixed disc segments (p =0.031), instrumentation of a more cephalad upper vertebra (p =0.007), and use of a halo vest (p <0.001). Among 156 patients who underwent ACSS after preventive measures were implemented, no cases of AAO were observed, but statistical significance could not be determined because of the limited sample size.
conclusionsWe systematically examined AAO prevention strategies and the potential effectiveness of 10 preventive measures. Despite these preventive measures, AAO cannot be prevented entirely; thus, rigorous monitoring after extubation is essential. Although the trend toward prolonged intubation is increasing, our findings suggest that immediate extubation is suitable for most patients.
