GRAvity- versus Wall suction-drIven large volume Thoracentesis: a rAndomized controlled Study (GRAWITAS study). Chest. 2024 Jul 17.
Abstract
Prior studies found no differences in procedural chest discomfort for patients undergoing manual syringe aspiration or drainage with gravity after thoracentesis. However, whether gravity drainage could protect against chest pain due to the larger negative pressure gradient generated by wall suction has not been investigated.
