Numerous surgeries require active, closed wound, surgical drains and evacuators (reservoirs). These surgeries can include, but are not limited to, general thoracic (heart, lung), lymph node, breast (mastectomy, explant, reconstruction), thyroid, abdominal, and some cosmetic surgeries (tummy tuck, face lift, breast augmentation, neck lift, arm lift). We suggest that you ask your doctor or surgeon if your surgery will require drains and evacuators (reservoirs). If the answer is yes and your surgery will require drains, then it is recommended that you purchase the C.U.D.D.L. Pouch for your healing journey.
