What characterizes purulent drainage from a surgical wound?

Purulent drainage from a surgical wound is characterized by a yellowish and thick consistency. This type of drainage typically indicates the presence of infection, as it is composed of pus, which contains dead white blood cells, bacteria, and cellular debris. The yellowish color often results from the breakdown of hemoglobin and the accumulation of bacteria, signaling a response from the immune system to fight off infection.

Recognizing purulent drainage is crucial for nursing practice, as it guides appropriate interventions and treatments. Early identification of infected wounds can help prevent complications and promote proper wound healing. Monitoring for changes in drainage characteristics is an essential part of post-operative care, allowing healthcare providers to take action if needed.
