Real-world effectiveness and safety of handheld ultrasound in pleural procedures

The use of ultrasound for pleural procedures is associated with a decreased risk of complications. Handheld ultrasounds allow for easier evaluation of the pleural space. Limited data exists for the use of such devices for pleural procedures. The primary objective of our study was to assess the effectiveness and safety of handheld ultrasound for pleural procedures. We performed a prospective observational study, including all consecutive patients who underwent pleural procedures using the handheld ultrasound between September 2021 and November 2023. A total of 332 pleural procedures were attempted with handheld ultrasound, of which 329 pleural procedures (99.1%) were successfully performed. The median volume of fluid drained was 500 (interquartile range: 300-800). Thoracentesis was performed in 127 patients (38.5%), tube thoracostomy in 179 patients (54.4%), and medical thoracoscopy in 23 patients (7.0%). Exudative pleural effusions were found in 264 patients (80.0%), of which 152 (46.2%) were determined to be due to infectious etiologies. A total of 4 (1.2%) patients had a complication due to the procedure. 2 patients (0.6%) had a pneumothorax, while 2 patients (0.6%) developed a hemothorax. A total of 101 patients had either low platelets (<50×109/L) or use of anti-platelet or anti-coagulant drugs. 128 patients (38.8%) were on positive pressure support during the pleural procedure. Our study shows that handheld ultrasounds are effective and safe for pleural procedures, including cases with septated pleural effusions and patients on anti-platelet or anti-coagulant drugs.
