Aldaghlawi F, Kurman JS, Lilly JA, et al. - By analyzing relevant data from Ovid MEDLINE, PubMed, Embase, the Cochrane Library, Scopus, and Google Scholar, researchers evaluated how digital drainage influences chest tube duration as well as hospital length of stay (LOS) after pulmonary surgery and spontaneous pneumothorax. The abovementioned sources were explored from inception through January 2019. The included studies comprised randomized controlled trials, cohort investigations, and case series of adult patients utilizing digital or traditional drainage devices for air leaks of either postsurgical or spontaneous pneumothorax origin. They reviewed 1,272 references, of these, 23 articles were included. Findings from most of the analyzed studies revealed that digital vs analog drainage systems did not differ significantly in terms of chest tube duration and hospital LOS in patients with air leak following pulmonary resection. For post spontaneous pneumothorax air leak, analog drainage systems resulted in shorter chest tube duration and hospital LOS, as suggested by the limited published evidence.
