Numerical and experimental investigation of air distribution in a full-scale experimental barn-integrated operating room for general thoracic surgery.

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
backgroundBarn-integrated operating rooms have been used in an effort to save space and improve operating room efficiency during orthopedic surgeries. This study aimed to investigate the feasibility of performing several thoracic surgeries in a barn-integrated operating room simultaneously.
methodsBoth numerical simulation and field measurement approaches were applied to evaluate the performance of the ventilation system for the barn-integrated operating room. Computational fluid dynamics (CFD) method was applied to simulate airflow velocity field and particle concentration field. On-site test of airflow velocities were measured with a thermal anemometer. Bacteria-carrying particle (BCP) deposition and distribution was estimated using passive air sampling (PAS) and active air sampling (AAS) methods during mock surgeries.
resultsThe airflow distribution and concentration contours showed the barn-integrated operating room to be highly effective in controlling the concentration of airborne bacteria in the operating fields. The airflow and bacteria count met the current standard of GB50333-2013 Specifications, and there was no evidence of air mixing between cabins.
conclusionsA barn-integrated operating room with several ultraclean operating tables in a single room would be a viable proposition for general thoracic surgeries in the future. As well as achieving a satisfactory level of contamination control, such an approach would reduce operating costs.
