Zhou J, et al. - Researchers aimed at determining the current strength of evidence for or against digital and traditional chest drainage systems following pulmonary surgery with regards to hard clinical endpoints and cost-effectiveness in this systematic review with meta-analysis. They included a total of 10 randomized controlled trials enrolling 1,268 patients in this study. Findings emphasized on the necessity for using a digital chest drainage system for patients who underwent pulmonary surgery to reduce the duration of chest tube placement, length of hospital stay and air leak duration.
