Overview
A Penrose drain gives fluid a temporary path out of a wound, but it does not tell you how much fluid has left or whether the underlying problem is resolving.
A Penrose drain gives fluid a temporary path out of a wound, but it does not tell you how much fluid has left or whether the underlying problem is resolving. The dressing is therefore both the collection surface and the nurse's main source of output information. A wet dressing may reflect expected postoperative drainage, while a newly dry dressing may signal improvement, obstruction, displacement, or a collection forming underneath. Safe assessment connects the drainage pattern with the patient's pain, vital signs, wound findings, drain security, and clinical trajectory. In Canadian NP practice, decisions about infection, source control, antimicrobial treatment, and drain manipulation must also remain within orders, provincial scope, competence, and local policy.
