Hypocapnia is associated with increased in-hospital mortality and 1 year mortality in acute heart failure patients.

Aims: Both hypercapnia and hypocapnia are common in patients with acute heart failure (AHF), but the association between partial pressure of arterial carbon dioxide (PaCO) and AHF prognosis remains unclear. The objective of this study was to investigate the connection between PaCO within 24 h after admission to the intensive care unit (ICU) and mortality during hospitalization and at 1 year in AHF patients.

Methods And Results: AHF patients were enrolled from the Medical Information Mart for Intensive Care IV database.

A novel drainage strategy using chest tube plus pleural catheter in uniportal upper lobectomy: A randomized controlled trial.

Background: In this study we explored whether one pleural catheter plus single chest tube drainage could achieve a noninferior drainage effect when compared with the traditional two chest tubes in uniportal video-assisted thoracoscopic surgery (VATS) for an upper pulmonary lobectomy.

Methods: Patients that underwent an upper pulmonary lobectomy from January to November 2020 were enrolled in this single-center, randomized, open-label, noninferiority trial. Prior to closure, patients were randomized to an intervention group who received an improved drainage strategy involving one pleural catheter with one chest tube (24 Fr), while traditional double chest tube drainage was applied for the control group.
