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.

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.

Abstract

A 37-year-old male smoker with asthma presented with status asthmaticus refractory to terbutaline, intravenous magnesium, continuous bronchodilators, steroids, heliox and theophylline infusion. He was intubated on hospital day 2 and cannulated for veno-venous extracorporeal membrane oxygenation (V-V ECMO) on hospital day 3 for refractory respiratory acidosis secondary to hypercapnia and hypoxemia despite maximum medical management over 4 days. He was started on inhaled isoflurane with improvement in peak airway pressures and respiratory acidosis, allowing for prompt weaning from V-V ECMO and extubation. Inhaled volatile anaesthetics exert a direct action on bronchiole smooth muscle causing relaxation with significant effect despite severely impaired pulmonary function. This treatment in patients on ECMO may allow for earlier decannulation and decreased risk of coagulopathy, ECMO circuit failure, infection, renal failure, pulmonary haemorrhage and central nervous system haemorrhage. However, major limitations exist in delivering volatile anaesthetics, which may make use inefficient and costly despite efficacy.
