Thoracentesis is an invasive procedure to remove fluid or air from the pleural space for diagnostic or therapeutic purposes. A cannula, or hollow needle, is carefully introduced into the thorax, generally after administration of local anesthesia.
One can end up in the Emergency Room from side effects like a collapsed lung.
An X-Ray and CAT scan indicated the lung was not collapsed and there was no mass in the abdomen. A new treatment will hopefully arrest the fluid accumulation.
She feels better now.
