1 · What the graph read from it

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.

Abstract

background and purposeThe aim was to investigate the clinical impact of the duration of artificial ventilation in stroke patients receiving mechanical thrombectomy (MT) under general anaesthesia.

methodsAll consecutive ischaemic stroke patients who had been treated at our centre with MT for anterior circulation large vessel occlusion under general anaesthesia were identified over an 8-year period. Ventilation time was analysed as a continuous variable and patients were grouped into extubation within 6 h ('early'), 6-24 h ('delayed') and >24 h ('late'). Favourable outcome was defined as modified Rankin Scale scores of 0-2 at 3 months post-stroke. Pneumonia rate and reasons for prolonged ventilation were also assessed.

resultsAmongst 447 MT patients (mean age 69.1 ± 13.3 years, 50.1% female), the median ventilation time was 3 h. 188 (42.6%) patients had a favourable 3-month outcome, which correlated with shorter ventilation time (Spearman's rho 0.39, P < 0.001). In patients extubated within 24 h, early compared to delayed extubation was associated with improved outcome (odds ratio 2.40, 95% confidence interval 1.53-3.76, P < 0.001). This was confirmed in multivariable analysis (P = 0.01). A longer ventilation time was associated with a higher rate of pneumonia during neurointensive care unit/stroke unit stay (early/delayed/late extubation: 9.6%/20.6%/27.7%, P < 0.01). Whilst stroke-associated complications represented the most common reasons for late extubation (>24 h), delayed extubation (6-24 h) was associated with admission outside of core working hours (P < 0.001).

conclusionsProlonged ventilation time after stroke thrombectomy independently predicts unfavourable outcome at 3 months and is associated with increased pneumonia rates. Therefore, extubation should be performed as early as safely possible.
