5-point airway (5-AIR) ultrasound protocol for confirmation of endotracheal intubation and position in paediatric patients undergoing surgery: A prospective observational study.
Article in Indian journal of anaesthesia, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background and Aims: We devised and compared the accuracy and time required for a 5-point airway (5-AIR) ultrasound (USG) protocol for confirming endotracheal intubation (ETI) and endotracheal tube (ETT) positioning (ETP) with the current reference standard of quantitative waveform capnography (QWC) and auscultation. Methods: In this prospective observational study, 75 American Society of Anesthesiologists physical status I or II children between 2 and 12 years undergoing elective surgery were recruited. ETI and ETP were confirmed clinically and sonographically using the 5-AIR USG protocol, which involves real-time tracheal USG followed by bilateral pleural and diaphragmatic ultrasonography. Results: There was no oesophageal intubation in this study; hence, the accuracy of the USG protocol for ETI could not be determined. For ETP, 68 patients had correctly placed ETTs. The 5-AIR USG protocol identified 4 out of 7 endobronchial placements, resulting in a sensitivity of 100%, specificity of 57.14%, and an overall diagnostic accuracy of 96%. The mean time for confirmation of ETI by QWC (20.77 s (standard deviation (SD): 4.11 s; 95% confidence interval (CI): 19.84, 21.70) was longer than real-time tracheal USG (2.11 s (SD: 0.31 s; 95% CI: 2.04, 2.18) ( Conclusion: The 5-AIR USG protocol was useful, fast, and demonstrated high diagnostic accuracy to confirm endotracheal intubation and position in paediatric patients. This protocol may be incorporated along with clinical signs, auscultation, and QWC to confirm endotracheal intubation and position.
